Heart failure (HF), characterized by excessive exertional dyspnea, is a common complication within the broad clinical spectrum of hypertrophic cardiomyopathy (HCM). HF has become an increasingly prominent management issue with the reduction in sudden deaths due to use of implantable defibrillators in this disease. Exertional dyspnea ranges in severity from mild to severe (New York Heart Association functional classes II to IV) and not uncommonly becomes refractory to medical management, leading to progressive disability, but largely in the absence of pulmonary congestion and volume overload requiring hospitalization...

Chronic heart failure (HF) is one of the main causes of mortality and morbidity worldwide and represents a growing challenge in interventional cardiology. Its prevalence is recently increasing due to the improvements in cardiac care with subsequent significant reduction in the HF acute mortality. HF may occur with either a reduced left ventricular ejection fraction (LVEF) (LVEF<40%, HFrEF) or a preserved EF (typically LVEF≥50%, HFpEF) indicative of diastolic dysfunction. Despite recent advances in drug therapies as well as in nonpharmacological strategies, including defibrillators, cardiac resynchronization therapy, LV assist devices (LVAD), mortality in HF remains high...

The tricuspid valve has historically received less attention than any other cardiac valve with regard to pathophysiology and surgical management. The tricuspid valve is part of a complex functional apparatus that includes the right atrium, right ventricle, and pulmonary circulation. Functional tricuspid regurgitation is the most common tricuspid valve disease and it occurs secondary to dilatation of tricuspid annulus and/or tethering of valve leaflets from right ventricular dilatation and dysfunction. However, recent expansion in the use of right-sided transvenous devices such as pacemakers and implantable defibrillators has been met with a parallel increase in the risk of organic tricuspid disease...

Patients with Duchenne muscular dystrophy (DMD) often have systemic manifestations with comorbid involvement of the cardiac and respiratory systems that increase the risk of anesthetic and perioperative morbidity. These patients frequently develop progressive myocardial involvement with cardiomyopathy, depressed cardiac function, and arrhythmias. The latter may necessitate the placement of an automatic implantable cardioverter defibrillator (AICD) insertion. As a means of avoiding the need for general anesthesia and its inherent potential of morbidity, regional anesthesia may be used in specific cases...

Hypertrophic cardiomyopathy (HCM) is a genetic myocardial disease usually characterized by asymmetric ventricular septal hypertrophy. HCM is an important cause of sudden cardiac death in adolescents and young adults. We are presenting a case report, ten years boy came in emergency with sudden loss of consciousness (witness cardiac arrest). Child was revived after cardiopulmonary resuscitation and send to coronary care unit. Echocardiography findings were suggestive of HCM. There was history of sudden death of her mother and maternal uncle...

A cardiac resynchronization therapy defibrillator (CRT-D) (Medtronic Inc. Protecta XT) was implanted in a 67-year-old man who had cardiac sarcoidosis with extremely low cardiac function. He had ventricular tachycardia which was controlled by catheter ablation, medication and pacing. The programmed mode was DDI, lower rate was 90 beats/minute, paced AV delay was 150 ms, and the noncompetitive atrial pacing (NCAP) function was programmed as 300 ms.After his admission for pneumonia and heart failure, we changed his DDI mode to a DDD mode because he had atrial tachycardia, which led to inadequate bi-ventricular pacing...

PURPOSE: Positive T wave polarity in lead aVR (TPaVR) is associated with a poor prognostic indicator in patients with heart failure reduce ejection fraction (HFrEF). Our aim was to investigate the relationship between positive TPaVR and mortality in patients with cardiac resynchronization therapy defibrillator (CRT-D). METHODS: We included retrospectively 224 HFrEF patients with CRT-D in sinus rhythm. Laboratory, electrocardiographic (ECG), and echocardiographic data were recorded...

INTRODUCTION: Experience with the subcutaneous implantable cardioverter-defibrillator (S-ICD) is expanding rapidly. However, data on long-term performance or complications related to elective generator replacement is lacking. METHODS: Follow-up (FU) data of all patients implanted between December 2008 and April 2011 were collected. Complications were defined as those requiring surgical intervention. Kaplan-Meier estimates for complication and shock rates, with corresponding 95% confidence intervals (CI), were calculated...

AIMS: Avoiding propofol in patients with Brugada syndrome has been suggested because of the theoretical risk of provoking ventricular arrhythmias, although propofol may be selected for conscious sedation during electrophysiological procedures in catheterization laboratories. This study aimed to document peri-procedural electrocardiographic changes and adverse events in patients with Brugada syndrome undergoing implantable cardioverter defibrillator (ICD) implantation using propofol sedation...

BACKGROUND: High-risk patients with hypertrophic cardiomyopathy (HCM) are identified by contemporary risk stratification and effectively treated with implantable cardioverter-defibrillators (ICDs). However, long-term HCM clinical course after ICD therapy for ventricular tachyarrhythmias is incompletely understood. METHODS AND RESULTS: Cohort of 486 high-risk HCM patients with ICDs was assembled from 8 international centers. Clinical course and device interventions were addressed, and survey questionnaires assessed patient anxiety level and psychological well-being related to ICD therapy...

We have previously shown a reduction in HF events with cardiac resynchronization therapy with defibrillator (CRT-D) in patients with mild heart failure (HF) and diabetes mellitus (DM). It remains unknown whether HF remission in DM patients with CRT-D translates into reduced mortality. The effects of CRT-D versus an implantable cardioverter-defibrillator (ICD) alone to reduce long-term mortality were assessed in patients with left bundle branch block with DM (n = 386) and without DM (n = 982), enrolled in the Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy (MADIT-CRT)...
