Programmed ventricular stimulation predicts arrhythmic events and survival in hypertrophic cardiomyopathy.

Background: Sudden cardiac death (SCD) risk stratification in hypertrophic cardiomyopathy (HCM) in the context of primary prevention remains suboptimal. The purpose of this study was to examine the additional contribution of programmed ventricular stimulation (PVS) on established risk assessment.

Methods: Two-hundred-and-three consecutive patients with diagnosed HCM and ≥1 noninvasive risk factors were prospectively enrolled over 19years.

Outcomes of Same Day Pacemaker Implantation after TAVI.

Background: Transcatheter aortic valve implantation (TAVI) is often associated with conduction disturbances, followed by permanent pacemaker (PPM) implantation. Because of the potential reversibility of these conduction disorders, controversy exists regarding the right timing of PPM implantation. TAVI is routinely performed under dual-antiplatelet and antithrombotic therapy, which poses an additional hemorrhagic risk on a same-day procedure.

Electrical storm is an independent predictor of adverse long-term outcome in the era of implantable defibrillator therapy.

Aims: Electrical storm (ES) is a life-threatening arrhythmia complication affecting patients treated with an implantable cardioverter defibrillator (ICD). Despite its increasing importance, existing data on prognosis and management of ICD patients affected by ES are limited and conflicting.

Methods: We prospectively studied 169 consecutive patients receiving an ICD.
