Percutaneous reconstruction of aortic isthmus atresia using coronary total occlusion technique.

Aortic isthmus atresia is an extreme form of coarctation presenting in adults and usually calls for surgical correction. In this report, we present our initial experience with the first four cases successfully treated percutaneously using dedicated coronary total occlusion wires and techniques. < This case series shows a technique to cross totally occluded coarctation using the coronary chronic total occlusion technique which has not been described in the literature till date.

A unique and unexplained ricochet leak post PCI - successfully treated with intra-coronary glue.

We herein describe a unique case of coronary artery perforation treated with covered stent with repeat cardiac tamponade resulting out of a fresh unexplained leak from a remote vessel (Ricochet) and successfully treated with intra-coronary injection of sterile synthetic glue, cyanoacrylate.

Cardiovascular dysfunction in symptomatic primary hyperparathyroidism and its reversal after curative parathyroidectomy: results of a prospective case control study.

Background: Cardiovascular mortality in primary hyperparathyroidism (PHPT) is attributed to myocardial and endothelial dysfunction. In this prospective, case-control study we assessed cardiovascular dysfunction in patients with symptomatic PHPT and its reversal after successful parathyroidectomy.

Methods: Fifty-six patients with symptomatic PHPT underwent two-dimensional echocardiography, tissue Doppler (diastolic function assessment), serum N-terminal pro-brain natriuretic peptide (s-NTproBNP, a myocardial damage marker), and endothelial- and smooth muscle-dependent vasodilatory response (vascular dysfunction) studies before, 3, and 6 months after parathyroidectomy; 25 age-matched controls were studied similarly.

Comparison of transradial and transfemoral artery approach for percutaneous coronary angiography and angioplasty: a retrospective seven-year experience from a north Indian center.

Background: With the increasing prevalence of coronary artery disease, percutaneous coronary artery procedures have become even more important. Our study has compared transradial to transfemoral artery approach for coronary procedures in Indian population.

Aims And Objective: Comparison of transradial and transfemoral artery approach for percutaneous coronary procedures.

Vitamin D deficiency, coronary artery disease, and endothelial dysfunction: observations from a coronary angiographic study in Indian patients.

Background And Methods: Vitamin D deficiency has been linked to an increased risk of coronary artery disease (CAD) and cardiovascular (CV) death. Endothelial dysfunction plays an important role in pathogenesis of CAD and vitamin D deficiency is postulated to promote endothelial dysfunction. Despite rising trends of CAD in Asians, only limited data are available on the relationship between vitamin D, CAD, and endothelial dysfunction.
