The case highlights the importance of screening for abnormalities of aortic arch and arch vessels in TOF patients for accurate presurgical planning and to predict the postoperative outcomes.

This practice is challenged by two recent randomized controlled trials (RCT). All the prior data is observational. We performed a meta-analysis of these 2 RCTs to determine if early surgical aortic valve replacement in this patient population is beneficial compared with the standard conservative therapy.

Surgical ASD closure, although still implemented, is cosmetically inferior to transcatheter closure. This study aimed to evaluate the feasibility as well as short- and long-term clinical outcomes of the right posterolateral minithoracotomy approach for surgical ASD closure. METHODS: In total, 102 consecutive patients underwent posterolateral minithoracotomy for ASD between January 2014 and December 2021 at our center. Early surgical outcomes, cosmetic findings, and skin perception were evaluated over 1 year of postoperative follow-up using a self-satisfaction survey (1: very good, 2: good, 3: normal, 4: not good, 5: bad), Cavendish score, and shoulder joint function (angles of flexion, extension, and abduction). RESULTS: No patient required conversion to median sternotomy. Only one patient required reoperation due to bleeding. Postoperative echocardiography revealed no residual shunt at discharge in all patients. The mean follow-up period was 3.7 years (range: 0.3-7.1 years), during which the questionnaire was answered by 69 of 98 patients who were evaluated after more than 1 year. The mean self-satisfaction survey scores for cosmetic findings and skin perception were 1.3 ± 0.6 and 1.2 ± 0.5, respectively. The Cavendish score was under Grade 1 in all patients. Shoulder flexion and abduction were normal at 180° in all patients, except one, while extension was normal at 50° in all patients, except three. CONCLUSIONS: Our procedure achieved not only good early surgical outcomes but also excellent long-term cosmetic and shoulder function results.

While cardiovascular ochronosis has been described resulting from alkaptonuria, it may also result from chronic minocycline use which is exceedingly rare. Cardiovascular ochronosis often presents with insidious development, often identified incidentally during aortic valve replacement (AVR). Herein, we describe the case of a 71-year-old male undergoing AVR and coronary artery bypass grafting found to have minocycline-induced ochronosis of the aortic valve and aorta. CONCLUSIONS: Given the rarity of this case, descriptions of cardiovascular ochronosis cases secondary to minocycline use are imperative in ensuring that it is on the differential diagnosis when identified by others in future cases. Additional care must be taken intraoperatively to ensure that the correct anatomy is identified as discoloration hinders visualization of the anatomy potentially resulting in unintentional consequences such as heart block or perivalvular leak as traditional visual cues for suture placement are distorted.

METHODS: A 10-year-old male patient with cranial and complicated cardiac HCD lesions that caused lower extremity peripheral arterial occlusion and aneurysmatic dilatation in the left ventricular apex is presented. RESULTS: Although the patient was in the pediatric age group, the Dor procedure was successfully applied to preserve the ventricular geometry. The Dor procedure for a ventricular aneurysm caused by a cardiac hydatid cyst (CHC) was rarely applied in the pediatric age group. CONCLUSION: In conclusion, this case differs from other CHCs previously reported in the literature due to the advanced stage of the disease, atypical clinical presentation, and rare complications despite the young age of the case. The surgical method used in treating the patient makes the subject more interesting.

After 4 months, symptoms of chest tightness and shortness of breath appeared. Electrocardiogram (ECG) revealed old myocardial infarction; color sonography and myocardial computed tomography revealed apical myocardial defect. He refused surgery and percutaneous transcatheter closure, and follow-up observation. After 22 months, the symptoms of chest tightness and shortness of breath aggravated. He recovered after percutaneous transcatheter closure, and was discharged. This case shows delayed closure is one of the possible options for patients without severe organ dysfunction or hemodynamic disturbance.

In this study, we aimed to determine the feasibility and benefits of robotic, beating heart mitral valve surgery. METHODS: From February 2019 to February 2022, 17 patients underwent robotic beating heart mitral valve surgery. Fourteen of the patients had previous cardiac surgery. The mean age was 58.1 ± 10.3. Dense periaortic adhesions, heavily calcified aorta, and low ejection fraction were retained as indications for beating heart surgery. RESULTS: Mitral valve replacement was performed in 14 patients. Mitral ring annuloplasty was performed in two patients with low ejection fraction (EF). A severe paravalvular leak was repaired in one patient. Additional tricuspid annuloplasties were performed in three patients. Cardiopulmonary bypass time were 185.6 ± 55 min. There were no cases of conversion to sternotomy or thoracotomy. No cerebrovascular event occurred in the follow-up. One patient died as a result of secondary hepatorenal syndrome and multiorgan failure. CONCLUSIONS: Robotic beating heart mitral valve surgery is a feasible and effective technique with favorable early and mid-term results, especially in patients who are not suitable for aortic cross-clamping, secondary to periaortic adhesions, severe aortic calcifications, and low ejection fraction.

We aimed to investigate the utilization of extracorporeal membrane oxygenation (ECMO) after PEA and potential risk factors. METHODS: Demographic characteristics, clinical and surgical data were collected for all patients who underwent PEA from December 2016 to June 2022. All factors were compared between patients in the ECMO group and those in the other group. The most characteristic risk factors were obtained by least absolute shrinkage and selection operator regression and support vector machine machine learning, and receiver operating characteristics (ROC) Curve analysis was performed to verify the diagnostic value of the obtained risk factors. RESULTS: A total of 117 patients underwent PEA, and 8 (6.8%) of them received ECMO treatment intraoperatively or postoperatively. There were significant differences between the two groups in terms of cardiac function, pulmonary vascular resistance (PVR), preoperative inflammation and cardiopulmonary bypass time. The PVR and neutrophil-to-lymphocyte ratio (N/L ratio) were the most characteristic risk factors with an area under the ROC curve of 0.847 (95% confidence interval [CI] = 0.7517-0.9420, p = .005) and 0.896 (95% CI = 0.803-0.989, p = .001), respectively. The ECMO group had higher PVR (1549.4 ± 600.7 vs. 952.9 ± 466.9 dyn.s.cm , p = .004) and N/L ratio (6.3 ± 5.6 vs. 2.4 ± 1.7, p = .001). CONCLUSIONS: PVR and N/L ratio can correctly predict who is likely to receive ECMO treatment after PEA. Therefore, addressing the preoperative inflammatory status might be beneficial but further research is needed.

The aim of this study is to assess the effectiveness of a new length measuring technique. METHODS: All consecutive patients with anterior leaflet prolapse/flail who underwent MVr using the described method between January 2020 and January 2022 at our institution were included in the analysis. Clinical and transesophageal echocardiography data were collected postoperatively and at 1-year follow-up. The primary outcome was freedom from mitral regurgitation (MR). Secondary outcomes were presentation with New York Heart Association (NYHA) class <2 and leaflet coaptation length ≥10 mm. RESULTS: Of 25 patients, 16 (64%) were males. A total of 15 (60%) had isolated anterior leaflet disease, while 10 (40%) had concomitant posterior involvement. Twenty patients with isolated MR (80%) underwent right anterior mini-thoracotomy, while 5 (20%) with associated valvular or coronary disease underwent sternotomy. The median number of chordae implanted was 2 [1-4]. Postrepair intraoperative MR grade was 0 in 23 patients (92%) and 1 in 2 (8%). Thirty-day mortality was 0%. De novo atrial fibrillation was 20%. At follow-up, mortality was 0%. No patients presented with moderate or severe MR. A total of 22 patients (88%) were in NYHA class I, while 3 (12%) in class II. The coaptation length was 11 ± 1 mm. CONCLUSIONS: The short-term outcomes of the described technique are good with adequate leaflet coaptation in all treated patients. Long-term results are needed to assess the stability and durability of this repair technique.

Median sternotomy remains the gold standard for most cardiac surgeries. To tackle certain risks with a re-sternotomy, alternative procedures such as the right anterolateral minithoracotomy have been explored. This review aims to compare the clinical outcomes of re-sternotomy (MS) versus right mini thoracotomy (MT) in mitral valve surgery. METHODS: A systematic, electronic search was performed according to Preferred Reporting items for Systematic Reviews and Meta-analysis guidelines to identify relevant articles that compared outcomes of the MS versus MT procedures in patients who have had cardiac surgery via a MS approach. RESULTS: Twelve studies were identified, enrolling 4514 patients. Length of hospital stay(MD = -3.71, 95% confidence interval [CI] [-4.92, -2.49]), 30-day mortality(odds ratio [OR] = 0.59, 95% CI [0.39, 0.90]), and new-onset renal failure(OR = 0.38, 95% CI [0.22, 0.65]) were statistically significant in favor of the MT approach. Infection rates(OR = 0.56, 95% CI[0.25, 1.21]) and length of intensive care unit (ICU) stay (MD = -0.55, 95% CI[-1.16, 0.06]) was lower in the MT group; however, the difference was not significant. No significant differences were observed in the CPB time(MD = -2.33, 95% CI [-8.15, 3.50]), aortic cross-clamp time MD = -1.67, 95% CI[-17.07, 13.76]), and rates of stroke(OR = 1.03, 95% CI[0.55, 1.92]). CONCLUSION: Right MT is a safe alternative to the traditional re-sternotomy for patients who have had previous cardiac surgery. The approach offers a reduced length of hospital stay, ICU stay, and a lower risk of new-onset renal failure requiring dialysis. This review calls for robust trials in the field to further strengthen the evidence.

As the population ages, patients undergoing valve degeneration and therefore considered for mitral valve surgery will naturally be getting older. We sought to evaluate whether mitral repair retained a survival advantage over replacement in patients ≥80 years old. METHODS: A retrospective cohort study was performed using data acquired from the United Kingdom National Adult Cardiac Surgery Audit for the outcomes of in-hospital mortality and postoperative cerebrovascular event (CVA). Individual multivariable logistic regression models were created to investigate adjusted associations between these outcomes and type of mitral valve operation, repair or replacement. Additionally, associations between the individual model parameters and in-hospital mortality and CVA were investigated. RESULTS: A total of 1140 patients underwent mitral repair (66.4%, median age 82.3), and 577 patients underwent mitral replacement (33.6%, median age 82.1). The overall age range was 80-92. The incidence of in-hospital mortality favored the repair group (4.4% vs. 8.3%, p = .001). Multivariable logistic regression modeling demonstrated an increased adjusted odds of in-hospital mortality for mitral valve replacement (MVR) (odd ratio [OR]: 2.01, 1.15-3.50, p = .01). The only other parameter associated with an increased adjusted odds of in-hospital mortality was postoperative dialysis (OR: 14.2, 7.67-26.5, p < .001). There was not a demonstrated association between MVR and perioperative CVA (OR: 1.11, 0.49-2.4, p = .8). CONCLUSIONS: In patients ≥80 years old, mitral valve repair (MVr) was shown to be associated with a decreased adjusted odds of mortality, with a null association with CVA. These results suggest that, if feasible, MVr should remain the preferred management strategy, even in the very elderly.

MATERIALS AND METHODS: The use of thoracoabdominal normothermic regional perfusion with extracorporeal membrane oxygenation device has allowed to perform HT after cDCD in our country. We present a successful case of heart transplantation using a graft from cDCD with 201 min cold ischemia time. DISCUSSION AND CONCLUSION: HT from cDCD could be a good alternative to brain dead donation. This experience suggests than nonlocal cardiac from cDCD could tolerate long periods of cold ischemia time and break the main barriers with this technique.

In this report, we describe a new technique for TAAA open repair that aims to minimize visceral organ ischemia times. Unlike typical Crawford extent II TAAA open repair, which begins with aortic clamping and proceeds from the proximal to the distal anastomoses, our method reverses the anastomosis order and minimizes aortic clamping. Between January 2016 and December 2020, we used this approach in 29 patients undergoing TAAA repair. We present one of these cases, a 29-year-old patient with progressive aneurysmal dilatation of a DeBakey type III chronic aortic dissection that extended beyond the aortic bifurcation. Our technique reduced aortic cross-clamping, left heart bypass, and internal organ and spinal cord ischemia times and appears to be safe and effective.

Endovascular thrombectomy (EVT) is a potentially life-saving intervention. We examined patients at our institution who had EVT to treat AIS post cardiac surgery. METHODS: We retrospectively reviewed a stroke database from January 1, 2016 to October 31, 2021 to identify patients who had undergone EVT to treat AIS following cardiac surgery. Demographic data, operation type, stroke severity, imaging features, management and outcomes (mortality and modified Rankin Score (mRS)) were assessed. RESULTS: Of 5022 consecutive patients with AIS, 870 underwent EVT. Seven patients (0.8%) had EVT following cardiac surgery. Operations varied: two coronary artery bypass grafting (CABG), two transcatheter AVR, one redo surgical aortic valve replacement (AVR), one mitral valve repair and one patient with combined aortic and mitral valve replacements and CABG. Meantime postsurgery to stroke symptoms onset was 3 days (range 0-9 days). Median NIHSS was 26 (range 10-32). Five patients had middle cerebral artery occlusion and two internal carotid artery (n = 2). Median time between onset of symptoms and recanalization was 157 min (range 97-263). Two patients received Intra-arterial Thrombolysis. All patients survived and were discharged to another hospital (n = 3), home (n = 2), or rehabilitation facility (n = 2). Median 3-month mRS was 3 (range 0-6). CONCLUSION: We report the largest case series of EVT after cardiac surgery. EVT can be associated with excellent outcomes in these patients. Close neurological monitoring postoperatively to identify patients who may benefit from intervention is key.
