Rhythm-Monitoring Strategy and Arrhythmia Recurrence in Atrial Fibrillation Ablation Trials: A Systematic Review.

Background: : The rhythm-monitoring strategy after catheter ablation (CA) for atrial fibrillation (AF) impacts the detection of atrial arrhythmia recurrence and is not well characterized. We performed a systematic review and meta-regression analysis to determine whether the duration and mode of rhythm monitoring after CA affects detection of atrial arrhythmia recurrence.

Methods: Databases were systematically searched for randomized controlled trials of adult patients undergoing first CA for AF from 2007 to 2021.

A Strategy of Lead Abandonment in a Large Cohort of Patients With Sprint Fidelis Leads.

Objectives: This study sought to examine outcomes of our approach to managing a large cohort of patients with Sprint Fidelis (Medtronic, Minneapolis, Minnesota) leads.

Background: The optimal management approach for patients with leads under advisory is unknown. Concerns regarding the risk of device infection and complications associated with delaying lead extraction have recently been suggested to argue against abandoning leads under advisory.

Bioprosthetic tricuspid valve dysfunction in patients with transvalvular or epicardial pacing leads.

Background: Dysfunction of native tricuspid valves due to transvenous pacing leads is well described. Patients with bioprosthetic tricuspid valve (BTV) who need ventricular pacing are often advised epicardial lead placement to avoid potential damage to the BTV although there are no data to support this.

Objective: The aim of the study was to assess the frequency of BTV dysfunction in patients with permanent transvenous right ventricular pacemaker lead and compare it to patients with epicardial leads.

Spectral Doppler interrogation of the pulmonary veins in atrial septal defect.

The various components of the pulmonary venous (PV) flow are linked to physiological and pathological changes that predominantly occur in the left heart. Thus, spectral Doppler interrogation of the PVs provides hemodynamic insight mainly into left-sided cardiac function. An exception to the dependence of PV flow on left heart events occurs in the setting of an atrial septal defect (ASD).
