Background and Aim: Attempting to place an aortic cross-clamp may complicate surgery and postoperative outcomes in patients who have mediastinal adhesions or in those with extensive aortic calcification. Although right-sided cardiac surgery via thoracotomy is not a new technique in these patients, robotic-assisted intracardiac repair without cross-clamping was not reported in a large group of patients previously. In this study, the safety of robotic-assisted cardiac surgery without aortic cross-clamping was examined. Methods: From January 2010 to March 2020, 304 patients underwent roboticassisted cardiac surgery in our center and in 25 of these patients (8.2%) with a mean age of 65.5 ± 20 years myocardial protection was succeeded with moderate hypothermic ventricular fibrillatory arrest. Severe pericardial adhesions or existence of highly calcified ascending aorta were the indications for fibrillatory arrest during robotic assistant surgery. Results: Most patients were in New York Heart Association Class ≥II (88.0%) and the mean logistic Euroscore value was 18.5 ± 22.3. The type of operations were mitral/tricuspid valve repair/replacement, cryoablation, atrial septal defect closure, and pericardiectomy. Cardiopulmonary bypass times were 141.5 ± 47 (minimum 77-maximum 252) min. There was no case of conversion to open thoracotomy or sternotomy. Hemiparesis was observed in one patient. Two patients with 78.2 and 81.9 Euroscore values had mesenteric ischemia and multiorgan failure, respectively, and died at postoperative period. Conclusions: Robotic-assisted cardiac surgery without cross-clamping may provide reasonable outcomes in patients with severe aortic calcification or mediastinal adhesions undergoing intracardiac repair. These acceptable outcomes may encourage surgeons to perform this approach in appropriate group of patients.
Atrial septal defect (ASD) is one of the most common congenital cardiac diseases. This pathology can be treated with percutaneous devices. However, some of the ASDs are not suitable for device closure. Also, there may be device-related late complications of transcatheter ASD closure. Currently, robotic surgical techniques allow surgeons to close ASDs in a totally endoscopic fashion with a high success rate and a low complication rate. This study demonstrates the basic concepts and technique of robotic ASD closure.
The relationship between epicardial adipose tissue (EAT) and coronary artery disease has been predominantly demonstrated in the last two decades. The aim of this study was to investigate the predictive value of EAT thickness on ST-segment resolution that reflects myocardial reperfusion in patients undergoing primary percutaneous coronary intervention (pPCI) for acute ST-segment elevation myocardial infarction (STEMI). The present study prospectively included 114 consecutive patients (mean age 54 ± 10 years, range 35-83, 15 women) with first acute STEMI who underwent successful pPCI. ST-segment resolution (ΔSTR) <70 % was accepted as ECG sign of no-reflow phenomenon. The EAT thickness was measured by two-dimensional echocardiography. EAT thickness was increased in patients with no-reflow (3.9 ± 1.7 vs. 5.4 ± 2, p = 0.001). EAT thickness was also found to be inversely correlated with ΔSTR (r = -0.414, p = 0.001). Multivariate logistic regression analysis demonstrated that EAT thickness independently predicted no-reflow (OR 1.43, 95 % CI 1.13-1.82, p = 0.003). Receiver operating characteristic curve analysis demonstrated good diagnostic accuracy for EAT thickness in predicting no-reflow [area under curve (AUC) = 0.72, 95 % CI 0.63-0.82, p < 0.001]. In conclusion, increased EAT thickness may play an important role in the prediction of no-reflow in STEMI treated with pPCI.
All patients undergoing cardiac surgery suffer deterioration in pulmonary functions. Pleurotomy seems to compound this with increased rates of atelectasis and pleural effusions. Moreover, preserving pleural integrity provides beneficial effects on pain score after coronary operations especially in the early postoperative period.
The hallmark feature of aortic interruption that is useful in differentiating it from aortic coarctation is the "complete absence" of continuity between both parts of the interrupted segment. In this study, we reviewed the 28 patients diagnosed with isolated interrupted aortic arch (IAA) who reached adult age (> 20 years), aimed to review the validity of the Celoria-Patton classification in the literature, and reported the first microscopic pathology of the IAA in an adult.
AimTo investigate the relation between use of bone wax and postoperative sternal dehiscence after cardiac surgery.Material and methodsFive thousnad three hundred and eighteen consecutive patients who underwent cardiac surgery between 1999 and 2009 were evaluated prospectively. Perioperative use of bone wax, perioperative data and outcome parameters were recorded. Multivariate logistic regression analysis was performed to define independent risk factors for postoperative sternal dehiscence.ResultsBone wax was used in a total of 1151 (21%) patients. Postoperative sternal dehiscence was detected in 88 (1.6%) patients. The postoperative sternal dehiscence rate was 1.4% in patients without bone wax and 2.5% in patients with bone wax (p = 0.001). The rate of bone wax use was 36.4% in patients with sternal dehiscence and 21.4% in patients without sternal dehiscence (p < 0.001). Independent risk factors for postoperative sternal dehiscence were defined as: age > 70 (OR = 1.9, 95% CI: 1.2-3.1, p = 0.005), chronic obstructive lung disease (OR = 2.4, 95% CI: 1.5-3.9, p < 0.001), use of bone wax (OR = 1.6, 95% CI: 1.03-2.5, p = 0.03), nonelective operation (OR = 2, 95% CI: 1.1-3.4, p = 0.009), and body mass index > 30 (OR = 2.2, 95% CI: 1.4-3.5, p < 0.001).ConclusionsOur findings suggest that use of bone wax may be associated with increased postoperative sternal dehiscence after cardiac surgery. Thus liberal use of bone wax should be restricted.
