Structured PICO
Does phased-array intracardiac echocardiography monitoring improve long-term cure and reduce PV stenosis in patients with atrial fibrillation undergoing pulmonary vein isolation?
P
Population
Patients with atrial fibrillation undergoing cooled-tip pulmonary vein isolation
I
Intervention
Phased-array intracardiac echocardiography monitoring with power adjustment guided by direct visualization of microbubble formation
O
Outcome
Risk of pulmonary vein (PV) stenosis and long-term cure
Intracardiac echocardiography monitoring during PVI allows for power adjustment that reduces PV stenosis and improves long-term cure.
Abstract
Intracardiac echocardiography improves the outcome of cooled-tip PVI. Power adjustment guided by direct visualization of microbubble formation reduces the risk of PV stenosis and improves long-term cure.
