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.

Radiofrequency catheter ablation of atrioventricular nodal reentrant tachycardia in a patient with orthotopic heart transplantation by bicaval anastomosis.

Patients with orthotopic heart transplantation may have a variety of arrhythmias. There are reports of successful radiofrequency catheter ablation of some of them. Two months after orthotopic cardiac transplantation by bicaval anastomosis, a 49-year-old man developed episodes of tachycardia.
