the most frequent congenital heart defects in the neonatal period are ventricular septal defects. ventricular septal aneurysms can rarely develop from an interventricular septal (ivs) defect in adults. we describe a 47-year-old man with an aneurysm in the ivs growing towards the right ventricle, which was confirmed by cardiac computed tomographic angiography and was missed by echocardiography.

pulmonary arterial hypertension (pha) is a frequent complication of congenital heart disease (chd), most commonly in systemic-to-pulmonary shunt lesions. in patients with an uncorrected left-to right shunt, pah will end up to eisenmenger’s syndrome, which is contraindication of surgery. what about patients with moderate to severe pah, who do not have criteria of eisenmenger’s syndrome; immediat...

Background: We investigated whether the lungheart ratio parameter (LHR) can be used to identify the optimum cut off frequency for Butterworth filter in 99mTc myocardial SPECT imaging. Materials and Methods: This study involved a cardiac phantom system consisting of cardiac insert in which 1.10 cm cold defect was inserted into its myocardium wall and filled with 4.0 μCi/ml (0.148 MBq/ml...

Introduction: Along with advances occurring in cardiopulmonary bypass (CPB) including improved anesthesia intubation and early surgical interventions, it has become possible to correct life-threatening congenital heart anatomic abnormalities in patients. Our study aimed to collect information from one of the most important centers of pediatric cardiac surgery in Iran since there is limited info...

Objective: Although coronary artery disease (CAD) is the leading cause of death in type 2 diabetic patients, it is frequently asymptomatic. Myocardial perfusion imaging (MPI) is reported to show ischemia in a significant number of asymptomatic diabetic patients. We studied the prevalence and severity of myocardial perfusion defects in asymptomatic diabetic patients and its clinical impact. Meth...

Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...
