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.

Rheumatic Mitral Stenosis with Incidental Wolff-Parkinson-White Syndrome: A Rare Association. Treated by Percutaneous Transmitral Commissurotomy and Radiofrequency Ablation.

The combination of Wolff-Parkinson-White (WPW) syndrome and rheumatic mitral stenosis (MS) is rare in clinical practice. The management of this condition primarily depends on the clinical picture. We describe a 26-year-old male patient with no significant previous medical history and who came for a routine medical assessment before entrance to a police academy service.

Long-term effects of cardiac resynchronization therapy on electrical remodeling in heart failure-A prospective study.

Introduction: Effects of cardiac resynchronization therapy (CRT) on arrhythmogenicity and sudden death have not been fully ascertained. CRT has been shown to increase transmural dispersion of repolarization (TDR) immediately on implantation, which may favorably remodel on long-term follow-up. However, such a hypothesis has not been prospectively evaluated.

Narrow QRS Tachycardia in a Patient with Tachycardiomyopathy: What Is the Mechanism?

A 50-year-old female presented with incessant palpitation of 2 weeks duration. She was hemodynamically stable and there was no evidence of heart failure. A transthoracic echocardiogram showed mild left ventricular (LV) dysfunction with LV ejection fraction of 45%.

Bundle branch reentry: A rare mechanism of ventricular tachycardia in endomyocardial fibrosis, without ventricular dilation.

Introduction: Bundle branch reentry as a mechanism of ventricular tachycardia (VT) in endomyocardial fibrosis (EMF) is not described.

Case Report: A 52-year-old woman with left ventricular (LV) EMF had VT needing cardioversion. She had mitral regurgitation and left bundle branch block, but no LV dilation or heart failure.

Acute outcome of treating patients admitted with electrical storm in a tertiary care centre.

Background: Electrical storm (ES) is a life threatening emergency. There is little data available regarding acute outcome of ES.

Aims: The study aimed to analyze the acute outcome of ES, various treatment modalities used, and the factors associated with mortality.

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.

Left sympathetic cardiac denervation in managing electrical storm: acute outcome and long term follow up.

Purpose: Left sympathetic cardiac denervation (LSCD) may be beneficial in treating electrical storm (ES) of varied aetiologies. The present study analyse the outcome and long term follow up of LSCD in treating ES.

Methods: This is a retrospective study of patients with ES who underwent LSCD.
