66±13 h and 401±297 ?g at 24 h, respectively p less then 0.05). Partial pressure of oxygen levels at 10 and 16 h during the postoperative intensive care unit stay were lower, while partial pressure of carbon dioxide levels at 24 h was higher in Group 1 than Group 2 (p less then 0.05). Conclusion The bupivacaine protocol is a relatively more useful analgesic method which produces improved results in blood gas analysis by reducing the effects of pain and shortens the length of intensive care unit stay. Low levels of free cortisol also confirm this finding.

Methods Between January 2010 and December 2015, a total of 231 consecutive patients (78 males, 153 females; mean age 50.3±15.9 years; range, 34 to 66 years) who underwent tricuspid valve annuloplasty using three different techniques were retrospectively analyzed. Tricuspid valve r epair w as p erformed w ith d e Vega a nnuloplasty t echnique (n=62, 26.8%), flexible ring (n=76, 32.9%) or Teflon strip (n=93, 40.3%). Postoperative data including vital signs, echocardiographic reports, functional status, and the rate of re-do surgeries were recorded. Pimicotinib in vitro Results Cardiopulmonary bypass times were statistically significantly shorter in the de Vega annuloplasty group (p less then 0.001). There was no significant difference among the groups in terms of the in-hospital mortality. Late postoperative tricuspid regurgitation grades, systolic pulmonary artery pressure, and right atrial diameters showed significant improvements, compared to baseline, in ring and strip annuloplasty groups. Conclusion Our study results demonstrate that suture-based approaches should be avoided. Instead of performing routine tricuspid ring annuloplasty, Teflon strip annuloplasty may be considered an alternative method in most cases, particularly due to controversy in selection of true ring size and high cost of this surgical material in the real-life setting.

Methods Between January 2012 and May 2017, a total of 44 patients (8 males, 36 females; mean age 33.86 years; range, 14 to 63 years) who underwent atrial septal defect repair through mini-thoracotomy or median sternotomy in our clinic were retrospectively analyzed. Pre-, intra-, and postoperative data of the patients were recorded. Results There was no significant difference in the cardiopulmonary bypass and cross-clamp times between the groups, although the duration of operation was shorter in the mini-thoracotomy group (p=0.001). No significant difference was observed between the groups in terms of early mortality, neurological complications, and residual atrial septal defect. The mean mechanical ventilation time and length of intensive care unit and hospital stay were statistically significantly shorter, and the amount of bleeding was statistically significantly lower in the mini-thoracotomy group (p=0.001 for all). Conclusion Mini-thoracotomy should be kept in mind as a favorable alternative to sternotomy following a satisfactory learning curve period with less cost and higher patient benefit.

Methods Medical data of a total of seven patients (4 females, 3 males; median age 11.7 years; range, 1 to 24 years) who underwent transcatheter occlusion of the antegrade pulmonary blood flow following Glenn shunt or Fontan operation between September 2014 and January 2017 were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, type of surgery, echocardiographic and cardiac catheterization findings were recorded. Results Four patients had a previous pulmonary artery banding operation, while three had pulmonary stenosis. Two patients had facial and upper extremity edema after Glenn operation, one had prolonged pleural effusion, one had prolonged pleural effusion after Fontan operation, and one developed dyspnea and effort intolerance several years after Fontan operation. In two patients, antegrade pulmonary blood flow was occluded to decrease systemic ventricular load before surgery. The Amplatzer Septal Occluder was used in five patients and the Amplatzer Vascular Plug-2 was used in two patients. Two patients developed transient, complete atrioventricular block during the procedure and the procedure was terminated early in one of these patients. Transient hemolysis was observed in one patient following the operation. Conclusion Transcatheter occlusion of antegrade pulmonary blood flow is an effective alternative to surgery in patients with hemodynamic compromise after Glenn shunt or Fontan operation.

Methods Between November 2010 and December 2016, a total of 100 consecutive arterial switch operations in 42 pediatric patients (25 males, 17 females; median age 17 days; range, 2 to 210 days) were performed in two centers. Among them, 42 patients had associated ventricular septal defect and were diagnosed with Taussig-Bing anomaly (n=15) or transposition of the great arteries and ventricular septal defect (n=27). Aortic arch anomalies were present in six patients (40%) with Taussig-Bing anomaly and two patients (7.4%) with transposition of the great arteries and ventricular septal defect (p=0.016). Coronary anomaly was observed in five (33.3%) and six (22.2%) patients, respectively. All patient had a large defect (multiple n=4), except for eight patients who had moderate defect in the transposition of the great arteries group. Results Early mortality was 13.
