Surgical treatment of atrial tachycardia arising from left atrial appendage
Key result
Surgical radiofrequency isolation and external closure of the left atrial appendage successfully restored sinus rhythm and improved ejection fraction from 35% to 65% in a patient with refractory atrial tachycardia.
Why the study?
Surgical radiofrequency isolation plus external closure of the appendage is an option in focal atrial tachycardia from the left atrial appendage refractory to catheter ablation.
Does surgical radiofrequency isolation and external closure of the left atrial appendage restore sinus rhythm in patients with refractory focal atrial tachycardia?
Population

Structured PICO
Does surgical radiofrequency isolation and external closure of the left atrial appendage restore sinus rhythm in patients with refractory focal atrial tachycardia?
P
Population
18-year-old male patient with tachycardia-induced cardiomyopathy (ejection fraction 35%) due to focal atrial tachycardia arising from the left atrial appendage, refractory to catheter ablation.
I
Intervention
Surgical radiofrequency isolation using AtriCure Synergy Ablation Clamp through left anterior mini-thoracotomy, plus external exclusion using AtriClip PRO device.
O
Outcome
Restoration of sinus rhythm
Surgical ablation and LAA exclusion is a viable option for focal atrial tachycardia arising from the LAA that is refractory to catheter ablation.
Cite This Study
Zengin et al. (2020) conducted a case report in Atrial tachycardia arising from left atrial appendage (n=1). Surgical radiofrequency isolation and external closure of the left atrial appendage was evaluated on Restoration of sinus rhythm and improvement in ejection fraction. Surgical radiofrequency isolation and external closure of the left atrial appendage successfully restored sinus rhythm and improved ejection fraction from 35% to 65% in a patient with refractory atrial tachycardia.
