Background:There are few studies for detecting rhythm abnormalities among healthy children and adolescents. The aim of the study was to investigate the prevalence of abnormal electrocardiographic findings in the young Iranian population and its association with blood pressure and obesity. Methods:A total of 15084 children and adolescents were exami...

Background: Structural heart disease (SHD) has great impacts on healthcare systems, creating further public health concerns. Proper data are scant regarding the magnitude of the affected population by SHD. Objectives: This study aimed to determine the prevalence of SHD among children and adolescents in an Iranian population. Methods: In this p...

Introduction: The autologous pericardium, treated or fresh, is used in reconstructive cardiovascular surgery. We aimed to describe the features of fresh pericardium utilized in right ventricular outflow tract (RVOT) reconstruction, years after the initial surgery. Methods: This cross-sectional study was performed on 72 patients (65.3% male, mean ag...

Background The standard transthoracic echocardiography has some limitations in emergent and community-based situations. The emergence of pocket-sized ultrasound has led to influential advancements. Methods In this prospective study, in the hospital-based phase, children with suspected structural heart diseases were enrolled. In the school-based ph...

Objectives Previous small-sized studies have demonstrated the safety and efficacy of mechanical pulmonary valve replacement (mPVR) in patients with congenital heart disease; however, the predictors of major complications and reoperation remained unclear. Methods In a retrospective study, we reported the mid-term outcomes of a large-scaled series o...

Introduction The superior cavopulmonary connection operation is one of the stages of the palliative surgical management for patients with functionally single ventricle. After surviving this stage, the patients are potential candidates for the final palliative procedure: the Fontan operation. Objectives This study aimed to analyze the outcomes of s...

Background: Anomalous origin of left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital malformation. We sought to evaluate in-hospital and mid-term outcomes of patients with a diagnosis of ALCAPA who underwent surgical repair. Objectives: The objective of this study is to evaluate the mid-term outcomes of surgical repair of AL...

Quadricuspid aortic valve is a rare anomaly, and most patients require surgery for aortic regurgitation in the 5th or 6th decades of life; only a few cases of aortic valve repair in childhood have been reported. A 3-year-old boy was scheduled for ventricular septal defect closure and aortic valve repair. Quadricuspid aortic valve was an incidental...

Abstract Introduction: The surgeons and their patients are now seeing the benefits and extendedpossibilities of minimally invasive cardiac surgery. Anterior mini-thoracotomy approach is agood alternative to median sternotomy since it reduces operative trauma, accelerates recoveryand yields a better cosmetic outcome. Our purpose is to explain the de...

Background A tissue valve is the prosthesis of choice in the majority of children and adults requiring pulmonary valve replacement (PVR). Mechanical valves, on the other hand, are more durable but require anticoagulation therapy and carry the elevated risk of thrombosis. The aim of this study was to investigate the long-term outcomes of mechanical...

Posterior root enlargement provides the implantation of suitable-sized prosthetic valves in patients with a small aortic root. The aim of this study was to evaluate the long-term results of posterior root enlargement in patients undergoing aortic valve replacement. Between 1997 and 2011, 103 patients with a small aortic annulus (indexed effective o...

Objectives This study aimed to develop new models for prediction of short-term mortality risk in on-pump CABG surgery using decision tree (DT) methods. Methods Between September 2005 and April 2006, 948 consecutive patients underwent CABG surgery at Rajaie Heart Center. Potential risk factors were reviewed and univariate and multivariate analysis...

Sub-valvular apparatus preservation (SAP) during mitral valve replacement (MVR) is not a new concept. Some surgeons prefer to excise the apparatus. The aim of this study was to reduce the risk of prosthetic valve dysfunction. This retrospective study included 151 patients with the mean age of 46 years who underwent MVR (Female/male = 93/58). In the...

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious and under diagnosed disorder with significant morbidity and mortality. For reasons that are still unclear, the lyses of blood clots does not occur in some survivors with acute pulmonary thromboemboli, which then evolve into the organization of the clot inside the pulmona...

From 2004 to 2008, 64 infants with large ventricular septal defects were managed using a two-stage surgical approach. In the first stage, banding of the main pulmonary trunk was performed. The defect was then repaired months later. Debanding of pulmonary artery was accomplished without the need for pulmonary artery reconstruction.

The main goal of this study was to assess the frequency of recurrent coarctation after repair using different surgical methods. Surgical results of repairs for coarctation of aorta (Co-A) in 188 patients under the age 14 years who were treated in Rajaee Heart Center, Tehran, Iran, were evaluated retrospectively. The most common methods included pat...

Left ventricular free wall rupture is responsible for up to 10% of in-hospital deaths following myocardial infarction. It is mainly associated with posterolateral myocardial infarction, and its antemortem diagnosis is rarely made. One of the medical complications of myocardial infarction is the rupture of the free wall, which occurs more frequently...

J Cardiovasc Thorac Res / 23 Background: Pulmonary thromboendarterctomy is a curative surgery. However, it is associated with high mortality and morbidity. It's accomplished under a period of circulatory arrest, thereby increasing the risk of surgical complications, especially neurologic sequelae. In present study, the surgical result of this proce...

The present study was aimed to identify the preoperative, intraoperative, and postoperative predictors of AF in a pure cohort of the patients with coronary artery disease who underwent CABG surgery. Between November 2005 and May 2006, 302 consecutive patients were included in this prospective study. All the relevant clinical, electrocardiographic,...

Coronary artery bypass grafting (CABG) is one of the leading operations performed worldwide. This treatment modality has been performed in Iran for several years; however, little is known about the current risk profile of Iranian cardiac surgical patients. The authors investigated the relationship between risk factors and mortality assessed by logi...

Behçet's disease is an uncommon multisystemic disorder that appears most often in the third or fourth decade of life. It is characterized by recurrent orogenital ulcers and ocular and cutaneous inflammatory lesions. Cardiovascular involvement, which may be arterial or venous, is rare but carries a particularly poor prognosis. Arterial involvement i...

Interrupted aortic arch is a complete luminal and anatomical discontinuity between two segments of the aortic arch. According to the site of interruption there are three types of this anomaly. As the nature of this anomaly is life threatening and that the complex corrective operation utilizing CPB and/or total circulatory arrest is associated with...
