Comparison of left bundle branch area pacing between patients with pacing-induced cardiomyopathy and non-ischemic dilated cardiomyopathy.

Introduction: Left bundle branch area pacing (LBBAP) seems to be an alternative to coronary sinus pacing in patients with non-ischaemic dilated cardiomyopathy (NI-DCM) with left bundle branch block (LBBB) and in pacing-induced cardiomyopathy (PICM). The aim of the study was to compare the response of LBBAP in severe forms of both entities.

Material And Methods: Prospective study of patients with severe forms of PICM and NI-DCM in NYHA II-IV who underwent LBBAP.

Spanish catheter ablation registry. 23rd official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2023).

Introduction And Objectives: We report the results of the 2023 Spanish catheter ablation registry.

Methods: Procedural data were collected and incorporated into the REDCap platform by all participating centers through a specific form.

Results: There were 104 participating centers in 2023 compared with 103 in 2022.

A novel approach for venous occlusion after endocavitary leads. The balloon-assisted tracking technique.

The balloon-assisted tracking technique can be useful in short venous occlusions that conventional venoplasty fails. This technique could be feasible and with an expected low complication rate.

Impact on daily clinical practice of the latest evidence on percutaneous closure of patent foramen ovale after cryptogenic stroke: a single-center experience.

Introduction And Objectives: At the end of 2017, three clinical trials demonstrated that, in selected patients, percutaneous closure of patent foramen ovale (PFO) after cryptogenic stroke (CS) reduces the risk of recurrence. Our aim was to determine the impact of these findings on routine clinical practice in a tertiary hospital.

Methods: Patients with CS and percutaneous closure of PFO during 2001-2020 were included.

Effect of New-Onset Left Bundle Branch Block After Transcatheter Aortic Valve Implantation (CoreValve) on Mortality, Frequency of Re-Hospitalization, and Need for Pacemaker.

New-onset conduction disturbances are common after transcatheter aortic valve implantation (TAVI). The most common complication is left bundle branch block (LBBB). The clinical impact of new-onset LBBB after TAVI remains controversial.

Atrioventricular Conduction Changes After CoreValve Transcatheter Aortic Valve Implantation.

Introduction And Objectives: Conduction disturbances often occur after CoreValve transcatheter aortic valve implantation. The aim was to analyze which cardiac conduction changes occur in patients with aortic stenosis treated with this type of prosthesis.

Methods: A total of 181 patients with severe aortic stenosis treated with this prosthesis and studied by electrocardiography between April 2008 and December 2013 were selected.

Optical coherence tomography evaluation of late strut coverage patterns between first-generation drug-eluting stents and everolimus-eluting stent.

Objectives: To compare strut coverage patterns between everolimus-eluting stent (EES) and first-generation drug-eluting stents (DES) at more than 12 months after successful implantation, using optical coherence tomography (OCT).

Background: No sufficient OCT data has been reported comparing late strut coverage patterns between EES and first-generation DES. The favorable late results after EES implantation could be related to lower rates of uncovered and malapposed struts.
