Clinical and Angiographic Profiles of Myocardial Infarction in a Young South Indian Population.

Introduction Myocardial infarction (MI) in young South Indians presents a shifting epidemiological landscape, challenging traditional perceptions of cardiovascular diseases. This study investigates the clinical and angiographic profiles of MI in this subgroup of the population in detail, emphasizing the interaction between lifestyle, environmental, and genetic factors that contribute to the incidence of MI in younger people. Methodology Utilizing a descriptive observational design, the study analyzed data from 70 young adults (aged 18-45 years) admitted to Frontier Lifeline Hospital, Chennai, with acute MI over six months.

Early multicenter experience of Melody valve implantation in India.

Background: Transcatheter valves provide a safe and effective alternative to surgery for treating dysfunctional right ventricular outflow tracts (RVOTs). We present our early multicenter experience of percutaneous pulmonary valve implantation (PPVI) using Melody valve (Medtronic Inc., Minneapolis, MN).

A multicentre retrospective study on quality and outcomes of cardiac rehabilitation programs in India.

Cardiac rehabilitation (CR) programs in India are comprehensive in nature, consist of multidisciplinary teams and demonstrate significant improvement in various clinical parameters. However, there is a disparity in patient evaluation, risk assessment, data collection and documentation. CR programs in India need to be streamlined to meet the quality indicators outlined by the international guideline recommendations.

MitraClip and mitral annuloplasty device as a bridge to transplantation.

A 42-year-old man with dilated cardiomyopathy and endstage heart failure was evaluated for heart transplantation. He received a MitraClip and Carillon annuloplasty device for functional mitral regurgitation as palliation for his heart failure. Subsequently, he underwent successful heart transplantation.

Percutaneous closure of symptomatic large tricuspid paravalvular regurgitation using two muscular VSD occluders.

Paravalvular leaks are common following valve replacement surgery. Majority are benign and do not require any active intervention. However, occasionally severe paravalvular regurgitation can produce heart failure and/or hemolysis, needing closure of the defect.

Spontaneous coronary artery dissection in men presenting with acute coronary syndrome, successfully managed by intravascular ultrasound-guided percutaneous coronary intervention.

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome. It is most commonly seen in young women, without atherosclerosis, in the peripartum period. Management options include conservative medical treatment, percutaneous coronary intervention or a surgical approach depending on the presentation, extent of dissection and luminal stenosis.

Use of IABP in contrast media-induced anaphylactic shock: the ultimate lifesaver.

Anaphylactic reaction to contrast media during selective coronary angiography is a rare occurrence. It can be occasionally resistant to medical treatment leading to cardiovascular collapse and death. The use of intra-aortic balloon pump (IABP) counter-pulsation when the supportive medical treatment fails during anaphylactic shock is not well documented in the literature.

Outcomes following PCI in patients with previous CABG: a multi centre experience.

Background: Limited data is available to guide operators as to the optimal revascularisation strategy in patients with previous CABG representing with angina.

Method: Retrospective analysis of 161 patients with prior CABG undergoing PCI in two centres between September 2005 and April 2008.

Results: 161 patients (132 male, 68 ± 8 years) underwent PCI at 126 ± 65 months after index CABG.

Telescoping catheter technique for enlarged aortas.

Selective coronary angiography in severely dilated ascending aorta is technically challenging and sometimes impossible. The Terumo "five-in-six" system uses an extra long 5Fr guide catheter in a standard 6Fr guide catheter, so that the tip of the 5Fr guide catheter protrudes beyond the tip of the 6Fr catheter allowing an extra reach. This system has been used successfully to advance balloon catheters across chronic total occlusions (Takahashi et al, Catheter Cardiovasc Interv 2004;63:452-456) and stent delivery beyond proximal obstruction point (Mamas et al, Catheter Cardiovasc Interv 2008;71:358-363).

Combined catheter ventricular septal defect closure and multivessel coronary stenting to treat postmyocardial infarction ventricular septal defect and triple-vessel coronary artery disease: a case report.

Ventricular septal defect following acute myocardial infarction is a rare but life-threatening complication. Early surgical closure improves survival but carries a considerable risk. Percutaneous transcatheter closure is an alternative but experience to date is limited.
