Late deterioration of left ventricular function after right ventricular pacemaker implantation.

Objectives: Right ventricular (RV) pacing induces a left bundle branch block pattern on ECG and may promote heart failure. Patients with dual chamber pacemakers (DCPs) who present with progressive reduction in left ventricular ejection fraction (LVEF) secondary to RV pacing are candidates for cardiac resynchronization therapy (CRT). This study analyzes whether upgrading DCP to CRT with the additional implantation of a left ventricular (LV) lead improves LV function in patients with reduced LVEF following DCP implantation.

Successful re-ablation of a permanent junctional reciprocating tachycardia with cryoenergy : Case report of a 19-year-old patient.

We report the case of a 19-year-old male patient who presented with a permanent junctional reciprocating tachycardia (PJRT). After a primarily successful radiofrequency ablation of a para-Hisian, midseptal, accessory pathway, recurrence of tachycardia was documented. Thereafter, successful ablation using cryoenergy was performed.

Successful intraprocedural anticoagulation with bivalirudin during pulmonary vein isolation in a patient with known heparin-induced thrombocytopenia type II.

We report the case of a 56-year-old female who presented with symptomatic paroxysmal atrial fibrillation. Anamnestic heparin-induced thrombocytopenia (HIT) type II was suspected, and a rapid diagnostic test showed antibodies against platelet factor 4. The heparin-induced platelet activation-assay was negative.

[Transseptal puncture after device closure of patent foramen ovale: Is it feasible?].

Case Report: The case of a 40-year-old woman with paroxysmal symptomatic atrial fibrillation and implanted occluder of a patent foramen ovale (PFO; AMPLATZER™ Septal Occluder, St. Jude Medical) is reported. Due to the symptomic atrial fibrillation, pulmonary vein isolation was planned.

[Recurrent microdislocation of pacemaker leads due to an aortic aneurysm of the aorta ascendens].

We report about a 79 years old female patient which was admitted due to a symptomatic AV block 3rd degree. The coronary angiography excluded a coronary artery disease and the echocardiography revealed a normal left ventricular systolic function. Therefore a dual-chamber pacemaker was implanted.

[Wide QRS complex tachycardia in a patient with ischemic cardiomyopathy and prior ventricular tachycardia ablation].

Case Report: This article reports the case of a 76-year-old patient with multiple implantable cardioverter defibrillator (ICD) interventions of the single chamber ICD. On admission the 12-lead electrocardiogram (ECG) documented a wide QRS complex tachycardia without clearly identifiable P waves. The patient had previously had two ventricular tachycardia (VT) ablations due to VT storms.

Incidence of adequate ICD interventions in patients with hypertrophic cardiomyopathy supposed to be at high risk for sudden cardiac death.

Introduction: Although the incidence of sudden cardiac death (SCD) is as low as 1%/year in un-selected patients (pts) with hypertrophic cardiomyopathy (HCM), higher-risk populations may benefit from prophylactic implantation of an ICD. Risk assessment in HCM is thus important and currently based on the presence or absence of different risk markers (RM).

Study Aim: The objective of this study is to correlate the incidence of adequate ICD interventions in HCM with the presence of different RM.

Adaptive servoventilation improves cardiac function in patients with chronic heart failure and Cheyne-Stokes respiration.

Background And Aims: Sleep disordered breathing (SDB), especially Cheyne-Stokes respiration (CSR) is common in patients with chronic heart failure (CHF). Adaptive servoventilation (ASV) was recently introduced to treat CSR in CHF. The aim of this study was to investigate the effects of ASV on CSR and CHF parameters.
