Background Cardiac resynchronization therapy (CRT) is one of the most successful heart
failure therapies to emerge in the last 25 years and is applicable to∼ 25–30% of patients …

Objectives: The goal of this study was to assess the contemporary and historical success
rates of transvenous left ventricular (LV) lead placement for cardiac resynchronization …

Aims There are limited and contradictory data on the effects of CRT with implantable
cardioverter defibrillator (CRT‐D) on mortality as compared with CRT with pacemaker (CRT …

In cardiac resynchronization therapy (CRT), the electrical impulse delivered by the left
ventricular (LV) lead may incidentally cause phrenic nerve stimulation (PNS). The purpose …

Background Cardiac resynchronization therapy (CRT) is one of the most successful heart
failure therapies to emerge in the last 25 years and is applicable to≏ 25–30% of patients …

The most frequent intraventricular conduction abnormality in heart failure is left bundle
branch block (LBBB), occurring in 25% to 30% of patients. Regionally delayed electrical …

Aims Left ventricular (LV) lead dislodgement occurs in about 10.6% of patients in the first 12
months after cardiac resynchronization therapy defibrillator implantation, and causes lack of …

Aims The aim of our study was to investigate the long-term efficacy and safety of transseptal
endocardial left ventricular lead implantation (TELVLI). Methods and results Transseptal …

Aims Suboptimal placement, phrenic nerve stimulation, and dislodgements of left-ventricular
(LV) leads are main challenges in cardiac resynchronization therapy. We investigated the …

Background Left ventricular (LV) lead implantation for cardiac resynchronization therapy
(CRT) is associated with lead dislodgement rates ranging from 3% to 10%, and some …
