radiofrequency atrial fibrillation ablation technique in patients with mitral valve surgery and left atrial reduction procedures
background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...
متن کاملMorphological features of the left atrial appendage in consecutive coronary computed tomography angiography patients with and without atrial fibrillation
The majority of intracardiac thrombi form in the left atrial appendage (LAA). Enlargement of this structure, together with certain morphological features, may indicate a predisposition to the formation of thrombi and subsequent cardioembolic stroke. Thus far, studies on LAA morphology have largely focused on those patients with atrial fibrillation (AF). Taking a different approach, we investiga...
متن کامل3D Intracardiac Echocardiography/CartoSound™ Imaging of Esophagus Guided Left Atrial Posterior Wall Ablation for Atrial Fibrillation.
Two imaging cases highlight the important role of 3D ICE/Cartosound™ in the intracardiac echocardiographic imaging of esophagus and Cartosound™ guidance of radiofrequency lesions delivered safely at the left atrial posterior wall adjacent to esophagus during atrial fibrillation ablation.
متن کاملComplete Isolation of the Left Atrial Posterior Wall (Box Lesion) to Treat Longstanding Persistent Atrial Fibrillation.
INTRODUCTION The left atrial posterior wall has been shown to play na important role in AF pathophysiology. OBJECTIVE Evaluate the efficacy of an ablation strategy designed to completely isolate the LA posterior wall, on top of PV isolation. Methods and Results: 25 pts (72% male age 65 ± 12 years) undergoing AF ablation for persistent or long term persistent AF. Mean AF duration was 11 ± 3 mo...
متن کاملLimited posterior left atrial cryoablation in patients with chronic atrial fibrillation undergoing valvular heart sugery.
OBJECTIVES We sought to evaluate whether a limited surgical cryoablation of the posterior region of the left atrium was safe and effective in the cure of atrial fibrillation (AF) in patients with associated valvular heart disease. BACKGROUND Extensive surgical ablation of AF is a complex and risky procedure. The posterior region of the left atrium seems to be important in the initiation and m...
