BACKGROUND Transcatheter closure of coronary artery fistulas has emerged as a successful alternative to surgery. We describe various techniques and short-term findings in 15 patients who were taken up for transcatheter closure of these fistulas. METHODS AND RESULTS Fifteen patients (aged 2-55 years; 12 males) with coronary artery fistulas underwent(More)
OBJECTIVE Renin-angiotensin system gene polymorphisms are associated with essential hypertension; angiotensinogen gene variants are considered potential genetic risk factors. The aim of this study was to investigate the contribution of the G-6A, T174M, M235T polymorphisms, genotypic interactions, and haplotypes toward essential hypertension. METHODS In a(More)
PURPOSE Takayasu arteritis (TA) is a rare form of inflammatory arteriopathy affecting the aorta and its major branches. Obstructive lesions of all arch vessels may lead to disabling neurologic symptoms. There is limited experience with endovascular revascularization in this situation. The present report describes immediate and follow-up results with(More)
BACKGROUND Phosphodiesterase-5 inhibitors produce a significant decrease in pulmonary vascular resistance in patients with idiopathic pulmonary arterial hypertension. We studied the effects of tadalafil, a phosphodiesterase-5 inhibitor, on short-term hemodynamics, tolerability, and efficacy over a 12-week period in patients of Eisenmenger syndrome having a(More)
BACKGROUND Studies on genes of endothelial and vascular homeostasis are inadequate in females. METHODS We investigated the role of 7 variants of ACE, AGT and NOS3 and their correlation with NO(x) levels and ACE activity in hypertension susceptibility in 910 case-controls of both genders. RESULTS Prevalence of alleles D of ACE I/D; -6A of AGT -6G/A;(More)
INTRODUCTION Chronological age, dental development, height and weight measurements, sexual maturation characteristics and skeletal age are some biological indicators that have been used to identify time of growth. Many researchers have agreed that skeletal maturity is closely related to the craniofacial growth, and bones of hand and wrist are reliable(More)
BACKGROUND The genes FTO and GNB3 are implicated in essential hypertension but their interaction remains to be explored. This study investigates the role of interaction between the two genes in the pathophysiology of essential hypertension. METHODS/PRINCIPAL FINDINGS In a case-control study comprising 750 controls and 550 patients, interaction between the(More)
Nitric oxide (NO), a potent vasodilator, plays a pivotal role in blood pressure regulation. Endothelial NO synthase gene (NOS3) polymorphisms influence NO levels. Here, we investigated the role of the -922A/G, -786T/C, 4b/4a, and 894G/T polymorphisms of the NOS3 and NO(x) levels in 800 consecutive unrelated subjects comprising 455 patients of essential(More)
