Long-term outcomes of percutaneous coronary intervention in patients with prior coronary artery bypass graft - A retrospective experience.

Objective: To evaluate the long-term clinical outcomes of percutaneous coronary intervention (PCI) in patients who had previously undergone coronary artery bypass grafting (CABG).

Method: A total of 219 patients who had a history of CABG and underwent PCI at tertiary care centre were retrospectively enrolled in this study. Clinical endpoints such as major adverse cardiac events (MACE; cardiac death, non-fatal myocardial infarction [MI], and target vessel revascularization), any death, cardiac death, MI, target vessel revascularization (TVR), and target lesion revascularisation (TLR) were reported at long-term follow-up.

Programmed ventricular stimulation in structural heart disease: Implications of patterns of ventricular arrhythmias induced to long-term outcomes.

Introduction: Currently available data gives some credence to utility of VT induction studies in patients with stable ischemic cardiomyopathy, there are some unresolved questions as to define sensitive threshold for low-risk and the prognostic relevance of ill sustained or non-specific tachycardia on induction study. We evaluated potential ability of VT inducibility to predict likelihood of SHD (Structural heart disease) patients for subsequent arrhythmic or adverse cardiac events.

Material And Methods: All consecutive patients with syncope/documented arrhythmia who had VT induction done were included and patients with VT storm, ACS,uncontrolled HF were excluded.

First-in-human evaluation of a novel balloon-expandable transcatheter heart valve in patients with severe symptomatic native aortic stenosis: the MyVal-1 study.

Aims: The aim of this study was to demonstrate the safety and efficacy of the next-generation balloon-expandable Myval transcatheter heart valve (THV) in an intermediate- or high-risk patient population with severe symptomatic native aortic stenosis.

Methods And Results: MyVal-1 was a first-in-human, prospective, multicentre, single-arm, open-label study. Between June 2017 and February 2018, a total of 30 patients were enrolled at 14 sites across India.

Three-year clinical and two-year multimodality imaging outcomes of a thin-strut sirolimus-eluting bioresorbable vascular scaffold: MeRes-1 trial.

Aims: Although the proof of concept of the bioresorbable vascular scaffold (BRS) is well documented, device-related adverse outcomes with first-generation BRS indicate longer-term surveillance. The current study provides insights into the safety and performance of the MeRes100, a novel second-generation sirolimus-eluting BRS, beyond one-year up to three-year follow-up (FU).

Methods And Results: A total of 108 enrolled patients with de novo coronary artery lesions who underwent implantation of MeRes100 as part of the first-in-human MeRes-1 trial were followed up clinically beyond one year at two and three years and with multiple modality imaging at six months and two years.

Comparison of Morphologic Findings in Patients with Dextrocardia with Situs Solitus vs Situs Inversus: a Retrospective Study.

Background: Studies on dextrocardia have been limited by low numbers. Hence, it is very difficult to find the most common diagnosis in patients with dextrocardia, who are seeking medical attention in tertiary care center.

Aims And Objective: To identify the most common diagnostic pattern in patients with dextrocardia with different situs.

Clinical Outcomes of patients with coronary artery disease who underwent FFR evaluation of intermediate coronary lesionS- COFFRS study.

Background: We undertook this study to validate the impact of FFR-guided coronary interventions among Indian patients, which is not readily available as of date. Our patients differ from their western counterparts, both in terms of risk profile (younger, more metabolic syndrome, lipid rich diet) as well as their coronary size.

Methods: We retrospectively evaluated 282 patients with intermediate stenosis in their coronary arteries, who underwent FFR to assess the functional severity of the lesion.

Flecainide challenge test: Predictors of unmasking of type 1 Brugada ECG pattern among those with non-type 1 Brugada ECG pattern.

Background: Many subjects in community have non-type 1 Brugada pattern ECG with atypical symptoms, relevance of which is not clear. Provocative tests to unmask type 1 Brugada pattern in these patients would help in diagnosing Brugada Syndrome. However sensitivity and specificity of provocating drugs are variable.

Radiofrequency Ablation of Left Atrial Reentrant Tachycardias in Rheumatic Mitral Valve Disease: A Case Series.

Background: Left atrial (LA) reentrant tachycardias are not uncommon in regions where rheumatic heart disease is prevalent. Some of these arrhythmias may be curable by radiofrequency ablation (RFA). However, there are limited data pertaining to this in existing literature.

Percutaneous valvuloplasty for mitral valve restenosis: postballoon valvotomy patients fare better than postsurgical closed valvotomy patients.

Aim: To compare the results of percutaneous mitral valvuloplasty (BMV) for mitral restenosis in post-BMV versus postclosed mitral valvotomy (CMV) patients.

Methods And Results: Ninety-two patients who underwent BMV for mitral restenosis were followed up prospectively. Of these, 28 patients had undergone previous percutaneous mitral valvuloplasty (PRIOR BMV) and 64 patients had undergone previous closed mitral valvotomy (PRIOR CMV).

Mahaim fiber accelerated automaticity and clues to a mahaim fiber being morphologically an ectopic or a split AV node.

Mahaim Fiber tachycardia characteristically causes a wide QRS tachycardia with left bundle branch morphology and left axis deviation, especially in young patients, having no structural heart disease. Mahaim fiber automaticity further cements the proposition of Mahaim fiber, due to its Atrioventricular (AV) node like property, being called as an ectopic AV node.

Efficacy and safety of combination of extended release niacin and atorvastatin in patients with low levels of high density lipoprotein cholesterol.

Objective: We investigated the safety and efficacy of combination therapy of extended release (ER) niacin and atorvastatin in patients with low HDL-C and compared the results with atorvastatin monotherapy.

Methods: This open label study recruited consecutive men and women who had coronary artery disease with HDL-C levels <35 mg/dL. These patients were already on atorvastatin therapy targeted to lower low density lipoprotein cholesterol (LDL-C), for a minimum period of 6 months.

Left hemothorax: a presentation of a late ventricular perforation caused by an active fixation pacing lead.

Ventricular perforation, late after ventricular lead placement at the right ventricular apex is rare, and though, commonly presents with chest pain, loss of pacing and/or sensing, and hemodynamic instability caused by cardiac tamponade, it can rarely cause left sided hemothorax needing surgical exploration.
