Unlabelled: The aim of the SYNSEQ (Left Ventricular Synchronous vs. Sequential MultiSpot Pacing for CRT) study was to evaluate the acute hemodynamic response (AHR) of simultaneous (3P-MPP ) or sequential (3P-MPP ) multi-3-point-left-ventricular (LV) pacing vs. single point pacing (SPP) in a group of patients at risk of a suboptimal response to cardiac resynchronization therapy (CRT).

Outcomes of leadless pacemaker implantation in patients with mechanical heart valves.

Introduction: Device infections constitute a major complication of transvenous pacemakers. Mechanical heart valves (MHV) increase the risk of infective endocarditis (IE) and pacemaker infection, requiring lifelong vitamin K-antagonists (VKA), which may affect patient management. Leadless pacemakers (LP) are associated with low infection rates, posing an attractive option in MHV patients requiring permanent pacing.

Safety and efficiency of a common and simplified protocol for pacemaker and defibrillator surveillance based on remote monitoring only: a long-term randomized trial (RM-ALONE).

Aims: This trial aimed to evaluate the safety and efficiency of a common and simplified protocol for the surveillance of cardiac implantable electronic devices based on remote monitoring (RM) in patients with pacemakers (PMs) and implantable cardiac defibrillators (ICDs) for at least 24 months.

Methods And Results: The RM-ALONE is a multicentre prospective trial that randomly assigned 445 patients in two groups, both followed by RM: the home monitoring-only (HMo) based on RM + remote interrogations (RIs) every 6 months and the HM + IO that adds in-office evaluations every 6 months to RM. Four hundred and forty-five patients were enrolled in the study, 294 PMs and 151 ICDs recipients.

Background: Pulmonary vein isolation is the cornerstone of ablation for persistent atrial fibrillation (AF). The role of balloon catheters in this patient population remains ill defined.

Cardiac Resynchronization Therapy With a Quadripolar Electrode Lead Decreases Complications at 6 Months: Results of the MORE-CRT Randomized Trial.

Objectives: The aim of this study was to test the hypothesis that a quadripolar left ventricular (LV) lead results in fewer LV lead-related events than a bipolar cardiac resynchronization therapy (CRT) system in a prospective randomized trial.

Background: Bipolar LV leads cannot be implanted at the optimal site in up to 10% of patients who need CRT, because of anatomic or technical challenges (pacing threshold, phrenic stimulation, or mechanical instability).

Methods: The MORE-CRT (More Options Available With a Quadripolar LV Lead Provide In-Clinic Solutions to CRT Challenges) trial enrolled 1,078 patients.

Usefulness of echo-guided cardiac resynchronization pacing in patients undergoing "ablate and pace" therapy for permanent atrial fibrillation and effects of heart rate regularization and left ventricular resynchronization.

An acute comparative study of right ventricular (RV) pacing and echocardiographically guided cardiac resynchronization pacing (CRP) was performed in patients who underwent "ablate and pace" therapy for permanent atrial fibrillation. It was hypothesized that optimized CRP guided by tissue Doppler echocardiography would exert an additive beneficial hemodynamic effect to that of rate regularization achieved through atrioventricular junction ablation. An acute intrapatient comparison of echocardiographic parameters was performed between baseline preablation values and RV pacing and CRP (performed <24 hours after ablation) in 50 patients.

Pacemaker malfunction or non-physiological ventricular pacing?

Pacemaker manufacturers have developed new algorithms to preserve intrinsic conduction in order to reduce unnecessary stimulation and looking for physiological pacing. This case report highlights some of the new challenges related to these algorithms which include possible ECG misinterpretations and inaccurate programming leading to potential negative consequences.
