However, infective endocarditis (IE) combined with anomalous double blood supply to the anterior descending artery has not been reported. CASE PRESENTATION: A 58-year-old male previously diagnosed with IE came to the emergency department with complaints of chest tightness and dyspnea. Further examination confirmed severe aortic valve regurgitation combined with IE and anomalous double blood supply to the anterior descending artery. The cardiopulmonary bypass surgery was performed by direct perfusion through the normal left and right coronary openings. After surgery, the heart started beating again normally without any cardiogenic ischemic events. CONCLUSION: Cardiopulmonary bypass by direct perfusion was safe in the patient with anomalous double blood supply to the anterior descending artery.

Recently, we have applied TAVI to the treatment of aortic regurgitation (AR). Compared with conventional surgical procedures, TAVI is less invasive and considered a useful option for these high-risk patients. In this study, we reported a patient who underwent transapical TAVI. The patient was a 52-year-old female with Takayasu arteritis (TA) for 25 years, as well as with severe aortic regurgitation, porcelain aortas, and heart failure. Transapical TAVI successfully was accomplished without neurological complications, and heart failure immediately improved postoperatively.

Frailty first was described in the seminal "Fried" paper, which constitutes the longest-standing and most well-recognized definition. This study aimed to assess the impact of the Fried and modified Fried frailty classifications on patient outcomes following cardiac surgery. METHODS: The PUBMED, MEDLINE, and EMBASE databases were searched from January 2000 until August 2021 for studies evaluating postoperative outcomes using the Fried or modified Fried frailty indexes in open cardiac surgical procedures. Primary outcomes were one-year survival and postoperative quality of life. Secondary outcomes included postoperative complications, intensive care unit (ICU) length of stay (LOS), total hospital LOS, and institutional discharge. RESULTS: Eight eligible studies were identified. Meta-analysis identified that frailty was associated with an increased risk of one-year mortality (Risk Ratio [RR]:2.23;95% confidence interval [CI]1.17 -4.23), postoperative complications (RR 1.78;95% CI 1.27 - 2.50), ICU LOS (Mean difference [MD] 21.2 hours;95% CI 8.42 - 33.94), hospital LOS (MD 3.29 days; 95% CI 2.19 - 4.94), and institutional discharge (RR 3.29;95% CI 2.19 - 4.94). A narrative review of quality of life suggested an improvement following surgery, with frail patients demonstrating a greater improvement from baseline over non-frail patients. CONCLUSIONS: Frailty is associated with a higher degree of surgical morbidity, and frail patients are twice as likely to experience mortality within one-year post-operatively. Despite this, quality of life also improves dramatically in frail patients. Frailty, in itself, does not constitute a contraindication to cardiac surgery.

MATERIAL AND METHODS: This research contains all patients diagnosed with congestive heart failure and NOMI between January 2011 to January 2020. The patients who had angiography or CT that showed occlusion of more than 50% in any of the main branches of the mesenteric artery or patients who presented with symptoms in correlation with a total occlusion were excluded from the study. Patients who underwent coronary heart surgery but were not diagnosed with congestive heart failure and those with atrial fibrillation also were excluded from the study. Patients divided into two groups, according to a medical database. RESULTS: A significant difference was found between the surviving and non-survivor groups in minutes, in terms of median time to segmenter intestinal resection (P = 0.042). CONCLUSION: An early diagnosis and surgical segmental intestinal resection before peritonitis worsens can be the key to better prognosis for NOMI patients.

Previous studies have shown that diabetes is a key pathogenic factor. But how diabetes is related to AKI in off-pump CABG patients still is in debate. Here, we aim to study the relationship between diabetes and AKI after off-pump coronary artery bypass grafting (off-pump CABG). METHODS: Patients who underwent off-pump CABG from April 2017 to December 2020 in The First Affiliated Hospital of USTC were enrolled in this retrospective study. AKI was defined and classified, according to the criteria proposed by the Acute Kidney Injury Network. The incidence risk of acute kidney injury was measured by logistic regression and compared. RESULTS: A total of 395 patients, who underwent off-pump CABG, were included in this study. The postoperative acute kidney injury rate for a patient with diabetes was significantly higher than for patients without diabetes (x2 = 5.09, P = 0.024). Logistic regression analysis showed that patients with diabetes have a much higher risk with acute kidney injury occurring after off-pump coronary artery bypass grafting (OR 1.852, 95% CI 1.161 - 2.954, P = 0.01). CONCLUSIONS: Diabetes is an independent risk factor for postoperative AKI for patients undergoing off-pump CABG.

Patients following redo valve surgery possess many attributes that place them at risk for PMV, yet few studies particularly focused on them. The purpose of this study was to identify perioperative variables associated with PMV in redo valve surgery. METHODS: A retrospective study, including 117 patients who underwent redo valve surgery from November 2017 to September 2021, was performed. The potential perioperative risk factors for PMV were collected. PMV was defined as the need for intubation and mechanical ventilation for >24 h, after completion of the operation. The clinical data were analyzed with univariate and multivariate analyses to identify risk factors for PMV following redo valve surgery. RESULTS: The incidence of PMV was 38.5% (N = 45). Multiple logistic regression analysis showed perioperative risk factors for PMV included advanced age (age>57 years) [odds ratio (OR) 3.043, 95% confidence interval (CI) 1.172-7.905, P = 0.022], low weight (weight ≤58 kg) (OR 2.798, 95% CI: 1.088-7.199, P = 0.033), EuroSCORE II ≥6.8% (OR 3.467, 95% CI: 1.364-8.817, P = 0.009), and VIS at 12 hours post ICU admission (VIS12) >10 (OR 5.613, 95% CI: 2.211-14.249, P < 0.001). CONCLUSIONS: In adult patients undergoing redo valve surgery, advanced age, low weight, high EuroSCORE II and a high VIS at 12 hours post-ICU admission were associated with PMV. Hemodynamic status after operation were more important than preoperative and intraoperative variables in predicting PMV.

METHODS: I/R model injury was induced by temporary left anterior descending coronary artery occlusion in Sprague-Dawley (SD) rats, macrophages isolated from bone marrow-derived macrophages (BMDMs) were induced to M2 polarization, and H9C2 cells subjected to hypoxia/reperfusion (H/R) were used to establish an in vitro model. I/R-induced rats and H/R-induced H9C2 cells were treated with M2-exos in vivo and in vitro, respectively. Masson staining was performed to observe myocardial fibrosis in rats. Immunohistochemical (IHC) staining of myocardial tissues showed the expression of NLRP3 inflammasome activation and pyrolysis. Exosomes derived from IL-4-treated macrophages (M2-exos) were detected by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and western bolt. Western bolt was performed to determine the protein level, including NLRP3, pro-caspase-1, cleaved caspase-1, pro-IL-1β, cleaved IL-1β, gasdermin D (GSDMD), and N-terminus of gasdermin D (GSDMD-N). RESULTS: Activity of NLRP3 inflammasome and existence of pyroptosis in the rats subjected to MI/R were significantly higher than those in the control (P < 0.05). Moreover, we confirmed the accumulation of ROS during I/R injury in cardiomyocytes. M2-exos protected against I/R injury and reduced activity of NLRP3 inflammasome and existence of pyroptosis, accompanied with attenuating oxidative stress. In vitro studies showed similar effects, H9c2 cells co-cultured with M2-exos could attenuated H/R-induced cell injury, while M2-exos suppressed the expression of NLRP3 inflammasome and pyroptosis (P < 0.05).

The benefits of revascularization versus medical treatment for ischemic heart failure remain controversial. Thus, we assessed a patient diagnosed with ischemic heart failure before and 3 months after coronary artery bypass grafting by myocardial radionuclide imaging. Findings of Tc-99m sestamibi myocardial perfusion imaging revealed that the degree and area of ischemia were significantly reduced, and the systolic function of the left ventricle improved compared with the preoperative value. This suggests the benefit of revascularization in cases of ischemic heart failure.

This study aimed to investigate the short- and intermediate-term efficacies of a staged hybrid technique vs. CABG in treating older patients with multi-vessel CAD. METHODS: Patients, who received elective revascularization for multi-vessel CAD between May 2016 and May 2018, were recruited. They were divided into the CABG group (N = 38) and HCR group (N = 38). The major adverse cardiovascular and cerebrovascular events (MACCE), including myocardial infarction and stroke, were recorded. The results of death and second revascularization also were recorded. RESULTS: In this study, 90.1% of patients received follow up for a median time of 24 months. At 60 days after surgery, the cumulative mortality in the CABG group was significantly higher than in the HCR group, but the incidence of second revascularization in the CABG group was markedly lower than in the HCR group. The incidence of MACCE was comparable between the two groups. CONCLUSION: In older patients with multi-vessel CAD, the mortality after CABG is higher than after HCR, but the incidence of second revascularization after CABG is lower than after HCR.

Additionally, the process may lead to complications like hematoma, infection, misdirection of the artery, pneumothorax, and arteriovenous fistula. In the case described in this report, all vascular ruptures effectively were repaired because when internal jugular vein placement was adopted, a dialysis catheter would go through the right internal jugular vein into the subclavian artery, then the ascending aorta via the cephalic trunk, and finally the ectopic catheter would be surgically removed. The patient was released from the hospital on the seventh postoperative day after maintaining stable vital signs throughout the procedure.

The recovery rate of AF is very low. Moreover, it is difficult for the intervention of a giant atrial septal defect, and it also is more difficult to perform atrial septal puncture and left atrial appendage (LAA) closure after ASD occlusion. Here, we report a case of a giant ASD and permanent AF. We find that the AF is significantly improved after atrial septal defect (ASD) occlusion and left atrial appendage (LAA) occlusion, which is manifested by spontaneous restoration and maintenance of normal sinus rhythm.

We present the case of a 50-year-old asymptomatic male patient with such a condition that was diagnosed by transthoracic echocardiography, coronary computed tomography angiography, and coronary angiography. The patient was treated by surgical fistula closure under cardiopulmonary bypass. The postoperative coronary computed tomography angiography showed the patient got a complete cure, and the patient remains asymptomatic after 5-year follow up.

Two sets of blood cultures revealed bacteremia, due to Pasteurella multocida, while computed tomography (CT) revealed a 47-mm descending aortic saccular aneurysm. After transfer to our hospital, the saccular aneurysm rapidly grew to 54 mm. An emergency thoracic endovascular aortic repair was performed, due to the aneurysm immediately rupturing after the CT scan. The patient was discharged on postoperative day 28.

METHODS: A prospective randomized controlled study was conducted from June 2021 to December 2021 at a provincial children's hospital in China. The difference of nutritional status between the intervention group and the control group after short-term nutritional support was compared. RESULTS: After one month of nutritional support, the weight, STRONGkids score, albumin, prealbumin, and hemoglobin in the intervention group significantly were higher than those in the control group (P < 0.05). The postoperative intensive care time and discharge time of the two groups significantly were lower in the intervention group than those in the control group (P < 0.05). CONCLUSION: The preoperative nutritional support of 1 month for infants with non-restrictive ventricular septal defect can effectively improve their preoperative nutritional status and promote postoperative recovery.

We report the case of a high-risk patient with extremely severe mitral insufficiency and difficult-to-debride annular calcification who received mitral replacement using a chimney technique. This approach enabled not only the minimization of mitral calcification debridement but also the reduction of surgery time. Consequently, the surgery was successful with a great postoperative outcome. Thus, this technique is a safe and feasible option to deal with intractable mitral annular calcification during mitral valve surgery.

There is increasing evidence that the month of birth (MOB) has been related to different health problems during life. The aim of this study was to identify the effect of MOB on the risk of deep sternal wound infections (DSWI) in patients after open-heart surgery. METHODS: The follow-up retrospective research was performed at the Department of Thoracic, Cardiac, and Vascular Surgery of the Hospital of Lithuanian University of Health Sciences. We analyzed the MOB of 201 patients, who underwent open-heart surgery between January 2017 and December 2018. The case group consisted of 46 patients, who suffered from DSWI. Multivariate logistic regression for the association between MOB and risk of DSWI was used. RESULTS: The results showed that the risk of DSWI was by four times higher for patients born in June-September months. The risk of developing DSWI in the case group was even higher for women, patients aged 70 years and younger, those overweight or obese, and patients who underwent only CABG surgery. CONCLUSION: Due to the growing evidence that the month of birth affects the onset of diseases, it is important to assess MOB as the potential risk factor for developing DSWI.

This paper analyzed the relevant data of this technology with hopes of improving cognition and treatment. METHODS: There were a total of 60 eligible cases of secondary TAR after proximal aortic surgery in our center from 2010 to 2020. The primary surgical procedures included aortic valve replacement (AVR), ascending aortic replacement, Bentall, hemi-arch replacement, and thoracic endovascular aortic repair (TEVAR). The data were analyzed using the IBM SPSS Statistics 23.0 for Windows™ and presented as the mean ± standard deviations and direct frequencies, as appropriate. RESULTS: The interval between two operations was 44.8±53.6 months, 24 cases (40%) underwent emergency operation, the recurrence of type A dissection included 51 cases, accounting for 85% of the causes of total arch re-replacement. In the second surgical procedures, the ascending + TAR + stented elephant trunk (SET) implantation accounted for 75.0%. The overall surgical success rate was 98.3%. Postoperative respiratory complications were the most common, including infection, pneumothorax and hemothorax in 21 cases (35.6%). The second most common complication was acute kidney injury (AKI) in six cases (10.2%), and neurological complications took place in three cases (5.1%). The 30-day mortality rate was 15.3% and the 1-, 3- and 5-year survival rates were 96.0%, 84.0%, and 76.0%, respectively. CONCLUSIONS: The recurrence of dissection is the main cause of TAR after proximal aortic surgery, followed by aneurysm and the resurgical criteria for aneurysm needs to be unified. In addition to TAR, SET also is widely used. Despite high early mortality, its long-term prognosis is acceptable.

METHODS: We retrospectively reviewed data of patients admitted to the TH between September 2015 and June 2017 for cardiac surgery. The decision to transfer a patient to the QH was based on a Society of Thoracic Surgeon-Predicted Risk of Mortality (STS-PROM) score of ≥ 3%, the potential need for hemodialysis, and other risk factors. The same team of surgeons performed operations at both hospitals. We analyzed the perioperative outcomes of the patients and the referral pattern. RESULTS: A total of 116 patients met eligibility criteria; 105 underwent surgery at the TH, while 11 were transferred to the QH. Among the 11 patients transferred to the QH, eight had a score of 3% (median = 8.2 [IQR 5.7-25.0]). The patients transferred to the QH prior to surgery had a significantly higher STS-PROM score (P = ≤ .001). Overall, the mortality of patients who underwent surgery at the TH was 0.9% (1/105); while surgeries at the QH had a mortality rate of 0% (0/11). CONCLUSION: The collaborative effort between high-volume cardiac surgery programs and emerging community-based hospitals showed acceptable outcomes in perioperative cardiac surgical mortality. Elevated STS-PROM scores (>3%), previous sternotomy and anticipation of coagulopathy, and low left ventricular ejection fraction or dilated ventricles are factors that influenced the need to transfer from a TH to QH.

However, it was found in our clinical practice that the incidence of delirium in some patients with aortic dissection (AD) remained high even after using DEX. The aim of the present study was to clarify whether the protective effects of DEX against delirium were different between Stanford type A and B AD patients during ICU stay. METHODS: Data of patients with Stanford type A or B AD who were treated in the ICU of our hospital between 2015 and 2018 retrospectively were reviewed. They were divided into four groups: A1 group (Stanford type A AD patients using DEX), A2 group (Stanford type A AD patients without using DEX), B1 group (Stanford type B AD patients using DEX), and B2 group (Stanford type B AD patients without using DEX). Patients in A1 and B1 groups received intravenous administration of DEX within 1 h admission to the ICU and after surgery or stent implantation at a loading dose of 1 µg/kg, followed by continuous infusion of 0.2-0.7 µg/(kg·h) for >24 h. The mortality rate, delirium incidence, length of ICU stay, and drug administration were compared between the four groups. RESULTS: After intravenous administration of DEX, the delirium incidence in B1 group was reduced significantly compared with that in B2 group (2.8% vs. 17.8%, P = 0.04), while there was no significant difference between A1 and A2 group (20.8% vs. 24.3%, P = 0.7). However, DEX administration significantly reduced the use of anti-hypertensive drugs (P = 0.04) and morphine (P = 0.02) in Stanford type A AD patients. CONCLUSION: The use of DEX reduced the incidence of delirium in Stanford type B AD patients during ICU stay, therefore reducing the risk of medical accidents and risk of rupture of the aortic dissecting aneurysm. The preventive effect of DEX against delirium in Stanford type A AD patients was not obvious, and whether increasing the dosage of DEX could enhance the therapeutic efficacy in this group of patients needs to be further observed in future studies.

Then we explored the relationship between hemodynamic data and short-term residual pseudolumen after thoracic endovascular aortic repair (TEVAR) and predict the latter through the former. METHODS: We collected the relevant data of 53 patients who underwent TEVAR in our hospital. They were divided into the A group (residual false lumen group) and B group (closed false lumen group), according to whether there was a residual false cavity around the stent recently after TEVAR. Three-dimensional reconstruction and CFD analysis of the thoracic and abdominal aorta was performed by DSCTA before the operation to obtain the aortic wall shear stress (WSS) and maximum blood flow velocity of the true and false lumen at the entrance, middle point of the long axis, and distal decompression port at the peak time of ventricular systolic velocity. Through the statistical analysis, we further studied the predictive value of hemodynamic data for residual pseudolumen. RESULTS: There was no significant difference in age, male, preoperative and postoperative thoracic and abdominal aorta DSCTA interval, history of hypertension, history of diabetes, smoking, Pt and APTT at admission between the two groups (P > 0.05). The blood flow velocity and shear stress at the entrance of the false lumen and the distal decompression port in the two groups were statistically significant (P < 0.05), while the other hemodynamic indexes were not statistically significant (P > 0.05). Binary logistic regression analysis further showed that the shear stress of the false lumen at the level of the distal decompression port (OR = 1.73, P = 0.01) was an independent risk factor for the residual false lumen around the stent in the early stage after TEVAR. The ROC curve analysis showed that the AUC area of the ROC curve corresponding to the shear stress of the false cavity at the level of the distal decompression port was 0.83, the best cross-sectional value was 9.49pa, and the sensitivity and specificity were 84.60% and 72.50%. CONCLUSIONS: The residual pseudolumen after TEVAR is related to the hemodynamic factors in the aorta before TEVAR. Preoperative hemodynamic data also have good predictive value. When the shear stress of the false lumen at the level of the distal decompression port is greater than 9.49pa, the probability of residual false lumen around the stent during the perioperative period significantly increases.
