Clinical impact of right ventricular pacing burden in patients with post-transcatheter aortic valve replacement permanent pacemaker implantation.

Aims: Patients who undergo permanent pacemaker (PPM) implantation after transcatheter aortic valve replacement (TAVR) have a worse outcome. The aim of this study was to identify risk factors of worse outcomes in patients with post-TAVR PPM implantation.

Methods And Results: This is a single-centre, retrospective study of consecutive patients who underwent post-TAVR PPM implantation from 11 March 2011 to 9 November 2019.

Risk Stratification of New Persistent Left Bundle Branch Block After Transcatheter Aortic Valve Implantation.

Previous studies reported that new-onset persistent left bundle branch block (NOP-LBBB) was related to worse outcomes after transcatheter aortic valve implantation (TAVI). However, these results can be confounded by the presence of permanent pacemaker (PPM) implantation before and after TAVI. Long-term outcomes and the risk stratification of NOP-LBBB not having PPM implantation before and after TAVI have not been fully investigated.

First case report: Late-onset coronary artery spasm after radiofrequency catheter ablation for atrial fibrillation in a Caucasian patient.

Most of the coronary vasospasms were found intraprocedurally, and it is very rare to see late-onset vasospasms that happened a few hours after uncomplicated ablations. The recognition of this rare but potentially life-threatening complication is important to improve the conventional practice of catheter ablation for patients with drug-refractory atrial fibrillation.

Risk Prediction Model for Cardiac Implantable Electronic Device Implantation After Transcatheter Aortic Valve Replacement.

Objectives: The aim of this study was to develop and validate a risk prediction model for high-grade atrioventricular block requiring cardiac implantable electronic device (CIED) implantation after transcatheter aortic valve replacement (TAVR).

Background: High-grade atrioventricular block requiring CIED remains a significant sequelae following TAVR. Although several pre-operative characteristics have been associated with the risk of post-operative CIED implantation, an accurate and validated risk prediction model is not established yet.

Sequential Use of Aminophylline and Theophylline for Temporizing Neck Cancer-Induced Carotid Sinus Syncope.

Carotid sinus syncope due to head and neck cancer is uncommon and the management is challenging. Permanent pacemaker implantation is generally considered but malnutrition with subsequent chemo-radiation increases the risk of device infection. This is a first case report of the sequential use of aminophylline and theophylline for pharmacological temporization.

Impact of Right Ventricular Pacing in Patients Who Underwent Implantation of Permanent Pacemaker After Transcatheter Aortic Valve Implantation.

Atrioventricular conduction disturbances requiring implantation of permanent pacemaker (PPM) are a common complication following transcatheter aortic valve implantation (TAVI). Previous registry data are conflicting but suggestive of an increased risk in heart failure admissions in the post-TAVI PPM cohort. Given the expanding use of TAVI, the present study evaluates the effects of chronic right ventricular pacing (RV pacing) in post-TAVI patients.

Prognostic value of electrocardiographic measurements before and after cardiac resynchronization device implantation in patients with heart failure due to ischemic or nonischemic cardiomyopathy.

Postimplant QRS narrowing may predict clinical response after cardiac resynchronization therapy (CRT), but identification of nonresponders remains difficult. We studied the predictive value of electrocardiographic characteristics for mortality or cardiac transplantation in patients after CRT. Patients who had electrocardiograms available for review from before and after CRT device implantation were identified from a clinical database.

Novel applications in catheter ablation.

Catheter based treatment of arrhythmia has gained significant attention during the last two decades. Due to the explosive development in ablation treatment of atrial fibrillation, huge interest in new tools was born to help in the atrial fibrillation ablation procedures. The aim of this review is to describe the role of these novel techniques and tools aimed at improving the implementation of catheter based ablations of atrial arrhythmias by focusing on the use of intra-cardiac echocardiogram and robotic navigation.
