Summary
Pulsed field ablation (PFA) combined with left atrial appendage (LAA) occlusion is a safe and feasible treatment for atrial fibrillation (AF) in patients with dextrocardia. This approach effectively manages rhythm and reduces stroke risk.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Dextrocardia presents unique challenges for atrial fibrillation (AF) interventions.
- Combined ablation and left atrial appendage (LAA) occlusion offer a single-procedure solution for AF management and stroke risk reduction.
- Pulsed field ablation (PFA) shows potential for AF procedures in dextrocardia, but data are limited.

01:29Disturbances in Heart Rhythm
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
