Chronic kidney disease (CKD) is a major contributor to morbidity and mortality in India. CKD often coexists with heart failure (HF), diabetes, and hypertension. All these comorbidities are risk factors for renal impairment.

Twiddler's syndrome is a rare cause of pacemaker lead dislodgement. A 61-year-old female patient was implanted with a defibrillator capable of cardiac re-synchronization therapy (CRT-D); 10 months later, she presented with uneasiness and vibratory sensations in the chest. Fluoroscopy revealed rotation of the pulse generator along its longitudinal axis and dislodgement of all three leads.

Methods: Eleven consecutive patients with acute ST-elevation MI underwent primary percutaneous coronary intervention (PCI) using a bio-engineered GENOUS EPC stent.
Results: Procedural success was 100%.
Diffuse pulmonary arteriovenous fistulae are rare, more so when unilateral. This article describes a 12-year-old boy with diffuse right-sided pulmonary arteriovenous fistula in whom prior percutaneous transcatheter coil occlusion has been attempted without success.The patient was subjected to ligation and transection of the right pulmonary artery and he is presently doing well.

The COSTAR I trial represents the first-in-man study of the CoStar Paclitaxel-Eluting Coronary Stent System evaluating three dose release formulations of paclitaxel in a bioresorbable polymer matrix in the treatment of de novo coronary lesions.
Methods: The COSTAR I Trial was a prospective, multi-center registry enrolling 87 patients in four Indian centers for treatment of up to two de novo lesions = 25 mm in length in a reference vessel 2.
Coronary aneurysm after stent implantation is a rare complication. Coronary aneurysms have been reported after drug-eluting stent implantation, but there has been no clear elucidation of time course, mechanism and therapeutic implications. We report two patients who developed coronary aneurysms within two weeks of the procedure and required surgical intervention to treat the complication.

M potential is a very useful guide during radiofrequency ablation of Mahaim pathway. During ablation, an accelerated rhythm with ORS morphology, identical to fully pre-excited QRS complex is observed, and has been labeled as Mahaim automatic rhythm.

It is usually possible to localize the earliest site of endocardial activation by conventional or newer three-dimensional mapping techniques. We report a case of ectopic atrial tachycardia, wherein the tachycardia was being repeatedly interrupted by mechanical trauma.

The activation of the coronary sinus from the left atrium occurs through muscle bridges, which may be discrete or form an intermingled continuum. These muscle bridges, if disconnected, may dissociate the coronary sinus from the left atrium, in which case the coronary sinus electrograms do not represent left atrial activation, and do not help to understand, or may cause misinterpretation of, the mechanism of supraventricular tachycardia.

There are, however, no data available with the use of eptifibatide, a more cost-effective, small-molecule GP IIb/IIIa blocker with a shorter half-life. In a prospective multicenter feasibility and efficacy study, we assigned 55 consecutive patients with AMI being taken up for primary stenting to receive eptifibatide just before the procedure (two boluses of 180 microg/kg 10 min apart and a 24-hr infusion of 2 microg/kg/min).
