OBJECTIVES The starting hypothesis was that some perimembranous ventricular septal defects can be closed safely and effectively with a Bard Rashkind double umbrella introduced through a long transvenous sheath. DESIGN A descriptive study of all patients who underwent attempted transcatheter umbrella closure of a perimembranous ventricular septal defect. Those patients selected for the study h...

BACKGROUND AND AIM In Congenital Heart Disease (CHD), shunting of blood occurs through the anatomical defects which lead to mixing of oxygenated and deoxygenated blood. Chronic hypoxia which occurs due to the above said mechanism has the potency to cause DNA damage in children with CHD. In chronic hypoxia, there is a liberation of Reactive Oxygen Species (ROS) due to tissue injury as a result o...

BACKGROUND Septal atrial tachycardia (AT) can occur in patients without structural heart disease and in patients with previous catheter ablation of atrial fibrillation. We aimed to assess septal AT that occurs after open-heart surgery. METHODS AND RESULTS This study comprised 20 consecutive patients undergoing catheter ablation of macroreentrant AT after open-heart surgery. Relevance to surgi...

The septal angle, an angle between the interventricular septum and the line connecting the sternum midpoint and thoracic vertebral spinous process, as measured by computed tomographic pulmonary angiography (CTPA), has been observed to be increased in patients with pulmonary hypertension (PH), but its meaning remains unclear. The aim of this study was to investigate the potential role of the sep...

abstract a 49-year-old man with lutembacher's syndrome associated with frontal meningioma referred to our hospital. he also suffered from exertional dyspnea. transthoracic echocardiography demonstrated mitral valve area of 1.48 cm2, moderate mitral stenosis, and left atrial dimension (lad) of 5.6 cm with no clot. tee revealed severe mitral stenosis, mitral valve area of 1.05 cm2 with wilki...

introduction pulmonary vein stenosis includes narrowing of one or more pulmonary veins that may have congenital or acquired causes. congenital pulmonary vein stenosis is a rare condition and also a rare cause for pulmonary hypertension. since identifying the etiology of pulmonary hypertension plays a crucial role in medical and surgical planning, we decided to introduce a rare case of pulmonary...

conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...

introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...
