Transeptal approach to ablation of left-sided arrhythmias does not lead to persisting interatrial shunt: a transesophageal echocardiographic study.

In experienced hands, antegrade left heart catheterization via a transeptal puncture is a safe and effective method of performing radiofrequency ablation on the left side of the heart. Persistence of atrial septal defect following transeptal puncture for mitral valvuloplasty has been widely reported although hemodynamically significant shunts are rare. To… CONTINUE READING
