Balloon angioplasty of native coarctation of the aorta was performed in 35 consecutive adolescents and young adults, aged 14 to 37 years (mean 22.6 +/- 7.1). Twenty-eight (80%) patients had isolated discrete coarctation, six (17.1%) had tubular hypoplasia of the aortic isthmus, and one (2.9%) had hypoplasia of the post-coarctation aorta. The peak systolic(More)
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)
Purpose: To compare the early and long-term outcomes of subclavian artery angioplasty in patients with aortoarteritis and atherosclerosis. Methods: Sixty-one subclavian artery angioplasties were performed in 55 consecutive patients with aortoarteritis (n=32) and atherosclerosis (n=23) between 1986 and 1995. An arch aortogram followed by a selective(More)
Accelerated coronary and peripheral vascular atherosclerosis is one of the most common and chronic complications of diabetes mellitus. A relatively recently analysed aspect of coronary artery disease in this condition is its silent or asymptomatic nature. We studied silent/asymptomatic myocardial ischaemia in unselected consecutive middle aged asymptomatic(More)
Four patients with aortitis and stenotic lesions of the aorta were successfully treated by percutaneous transluminal balloon angioplasty. The peak systolic gradient across the constrictions decreased from 82.5 +/- 35.7 to 37.5 +/- 18.5 mm Hg immediately after dilatation. Repeat angiography in the first three patients performed 2 months later showed a(More)
Conventional risk factors for coronary heart disease (CHD) do not completely account for the observed increase in premature CHD in people from the Indian subcontinent or for Asian Indians who have immigrated to the USA. The objective of this study was to determine the effect of immigration to the USA on plasma levels of lipoprotein [a] (Lp[a]) and other(More)
OBJECTIVES The purpose of this study was to explore the association between lipoprotein (a) [Lp(a)] levels, apo(a) isoforms and family history of premature coronary artery disease (CAD) in young Asian Indians. DESIGN AND METHODS 220 patients (age <40 years) with angiographic evidence of CAD and 160 age matched healthy controls were enrolled for the study.(More)
Between January 1997 to May 1998, 37 consecutive patients underwent high speed rotational atherectomy with adjunctive balloon angioplasty for the management of first-time diffuse variety of in-stent restenosis in the native coronary arteries. Their age ranged from 38 to 71 years (mean 54.3 +/- 9.7 years). All the patients underwent initial stent(More)
