Successful catheter ablation above aortic sinus cusp approach
eliminating the ventricular arrhythmia arising from the myocardial
crescent beneath the interleaflet triangle : LGE-MRI assessment
Abstract
A 61-year-old female with 50000 ventricular premature contractions and
reduced left ventricular ejection fraction of 35% referred to our
center. Although the origin was considered to be originated from the
junction between the left and right coronary cusp, a single
radiofrequency application above the aortic sinus cusp could eliminate
it.
