OBJECTIVEThe present study was conducted to investigate the feasibility and efficacy of transcatheter closure of ruptured sinus of Valsalva aneurysm (RSVA).

METHODSFour patients (3 females) aged 7-57 years with RSVA (3 congenital RSVA and 1 post-surgery RSVA) were involved in the present study. Two-dimensional and color Doppler echocardiography revealed the ruptures of right coronary sinus into right ventricle in all cases. The echo estimated size of the defect was 2-10 mm. After the establishment of the arterio-venous wire loop, Amplatzer Duct Occluder (ADO) was successfully deployed by antegrade venous approach in all patients. The diameter of the occluder was chosen to be at least 1 to 2 mm larger than defect.

RESULTSThe defects were successfully occluded without any complications. On the follow-up 3 months after operation, there was no device embolization, infective endocarditis and aortic regurgitation.

CONCLUSIONTranscatheter closure is a feasible and effective modality for RSVA without other anomalies.
