Clopidogrel resistance and its effect on clinical outcomes in acute coronary syndrome.

Aim: The genetic polymorphism of CYP2C19 influences clopidogrel metabolism and resistance. Aim was to assess the association between CYP2C19 loss of function variation, clopidogrel resistance based on platelet reactivity units and clinical outcomes.

Methods: A total of 668 patients of Acute Coronary Sundrome (ACS) who underwent Percutaneous Coronary Intervention (PCI) were subjected to genetic screening and 143 patients undrewent platelet function test to study the association between drug metabolization and its effects based on platelet reactivity unit values.

Transcatheter aortic valve implantation using coplanar and cuspal overlap techniques in Indian patients.

Introduction: Transcatheter Aortic Valve Implantation (TAVI) techniques gradually evolved since 2002 and have undergone various refinements. Achieving optimal implantation depth has become crucial for good long term outcome. High implantation decreases the likelihood of conduction disturbances.

Percutaneous Extraction of Deployed Coronary Stent During Retrieval of Jailed Buddy Wire.

Retrieval of a buddy wire following coronary stenting of long, tortuous, and calcified lesions runs the risk of wire entrapment and stent deformation. We report a case of successful percutaneous extraction of a longitudinally deformed coronary stent during retrieval of jailed buddy wire from the left anterior descending artery. ().

Preliminary genome wide screening identifies new variants associated with coronary artery disease in Indian population.

Aim: Coronary artery disease (CAD) is a major health problem in developed and developing nations. Development of CAD involves a complex interaction between genetics and lifestyle factors. Individuals with high-risk genetic predisposition along with poor lifestyle are more inclined to the development of CAD.

Minimizing scattered radiation dose in cardiac catheterization laboratory during interventional procedures using lead free drape - MILD study.

Objective: RADPAD is a lead-free sterile drape that reduces scattered radiation during fluoroscopic procedures. We aimed to study the effect of using RADPAD on primary operator (PO) and secondary operator (SO) during coronary angiography (CAG) as well as percutaneous coronary intervention (PCI).

Methods: 137 patients undergoing elective CAG and PCIwere randomized in a 1:1 pattern with or without the RADPAD.

Spontaneous closure of grade IV coronary perforation.

Previous coronary artery bypass surgery (CABG) is an independent risk factor for coronary perforation (CP) during percutaneous coronary intervention (PCI) because of complexity of the cases. However in patients with prior CABG surgery, cardiac tamponade is rare because of local or regional pericardial adhesions.

Assessing safety of leadless pacemaker (MICRA) at various implantation sites and its impact on paced QRS in Indian population.

Background: In this study we report our experience in implanting MICRA TPS (transcatheter pacing system) at various RV sites; observing its safety, and impact on paced QRS in Indian population.

Material & Methods: 35 patients with MICRA TPS deployed from March 2017 to December 2019 at Army Hospital Research and Referral, New Delhi, at RVOT, apical septum and mid septum of RV were enrolled in the study. These patents were followed up and impact of implantation site, procedure related complications, change in pacing parameters, left ventricular ejection fraction and duration of paced QRS were monitored.

Giant right atrial myxoma presenting as right heart failure: a rare manifestation.

A 37-year-old man was presented in outpatient clinic of cardiology department with symptoms of easy fatigability and progressive increasing generalised anasarca since 5 months. Echocardiogram showed large mass of 9.8×7.

Left Atrial Myxoma from Anterior Mitral Valve.

Primary cardiac tumors are relatively rare, and myxoma, the most common variety, is found predominantly in the left atrium. Clinical presentation varies from asymptomatic incidental masses to serious life-threatening cardiovascular complications. Some cases are difficult to diagnose, as symptoms can be nonspecific.
