Objective To discuss the clinical effects and security of transcatheter closure of ruptured aneurysm of valsalva sinus (RAVS).   Methods A 28-year-old male patient admitted in our hospital on September 7

2007

was diagnosed as ruptured aneurysm of right valsalva sinus drained into right atrium

and accepted transcatheter closure. During the regular one-month interval follow-up

echocardiography and ECG were performed. Cardiac murmur

pressure and size of each chamber before and after transcatheter closure were analyzed retrospectively.   Results Cardiac murmur disappeared right after successful occlusion with a 12/14 mm domesticmade PDA occluder

and the pressure of right atrium

right ventricle and pulmonary artery decreased respectively from 21/10 mmHg

52/2 mmHg and 50/14 mmHg to 14/5 mmHg

24/0 mmHg and 33/15 mmHg. Left ventricular internal diameter decreased from 57 mm before transcatheter occlusion to 49 mm three days after occlusion. No complications occurred.   Conclusion Transcatheter closure of RAVS is safe and effective

and can substitute surgical operation in some patients of RAVS.
