Background:Ventricular septal defects (VSD) is one of the most frequent congenital cardiac malformations and cardiac conduction disorders are still one of the serious postoperative complications in this surgery.Objectives:This study aimed to compare the incidence of conduction disorders with the use of continuous compared to interrupted suturing techniques in VSD surgical repair.Patients and Methods:Previously recorded data of 231 patients who underwent surgical closure of VSD between January 2009 and January 2012 at the Rajaie cardiovascular medical and research center were retrospectively reviewed. VSD surgical repair was performed using continues suturing technique in group A patients (n = 163, 70.6%) and interrupted suturing technique in group B patients (n = 68, 29.4%).Results:The most common concomitant congenital anomaly was Tetralogy of Fallot (27.3%). Twenty-four (10.4%) patients had intraoperative cardiac arrhythmia, including 19 (8.2%) transient and 5 (2.2 %) permanent arrhythmia. During their ICU stay, ventricular arrhythmia and complete heart block were observed in 34 (14.7%) and 5 patients (2.2%), respectively. At the time of the last follow-up, incomplete right bundle branch block (RBBB), complete RBBB, RBBB with left anterior hemi-block, and complete heart block were identified in 84 (36.4%), 42 (18.2%), 29 (12.6%), and 5 patients (2.2%), respectively. The results revealed that group A patients were most likely to have had cardiac arrhythmias during their ICU stay and at the time of last follow-up (P < 0.001), while the intraoperative incidence of cardiac arrhythmia during surgery was not statistically significant between the two groups (P = 0.06).Conclusions:In the absence of any statistical differences in the other risk factors between the two groups, the difference in the incidence of conduction disorders can be attributed to the type of suturing used during the procedure.

Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a very rare congenital heart defect. Herein, we describe three cases of ARCAPA in an 8 months old, 18 months old, and 4 year old child. Two cases were incidentally diagnosed using a computed tomographic angiograph, and the other was incidentally diagnosed using a coronary angiograph. These cases underwent a reimplantation technique on diagnosis and resulting in positive clinical outcomes during the follow-up period which was a mean of 1.5 years.

Introduction:Left ventricular free wall rupture (LVFWR) is a frequent cause of death after acute myocardial infarction, and its repair remains a surgical challenge.Case Presentation:TachoSil® is a ready-to-use equine collagen patch which has been successfully used for hemostasis in cardiovascular surgery. However, a limited number of studies have reported its application for LVFWR repair. In this study, we describe our initial experience using TachoSil® for LVFWR repair.Conclusions:A hemodynamic study was acceptable at a 12-month follow-up, and no complication was seen.
