Objective:To investigate the clinical effects,security and the recently follow-up outcomes of transcatheter occlusion of ruptured sinus of Valsalva aneurysm(RSVA).Methods:Seven patients including six with the rupture of the right coronary sinus of Valsalva and one with the rupture of the nonecoronary sinus of Valsalva shunting into the right atrial were involved in the study and had been undergone transcatheter interventional occlusion.Observvation on echocardiography,electrocardiography,blood and ruine routine test,liver and kidney function test were performed instantly and on the follow-up 1,7 days after operation,and also echocardiography,electrocardiography,X-rays on the follow-up 30,90,180 days.Results:The width size of ruptured basic/top of RSVA of seven patients’ was(9.286±1.604/5.914±1.078)mm on ehocardiography,and(10.286±1.496/6.5±1.384)mm on assending aorta angiography.The seven patients were all accepted PDA occluder.And the diameter of occluders’ was(12±1.623)mm.Five patients han been undergone successful transcatheter closure without residual shunt.There were no hemolysis and aortic regurgitation postoperatively.Left ventricular diameter had been decreased significaterly at 7,30,90,180 days after operation than before.The occluder had no influence on the aneurysm,the ostil of the coronary artery,aortic valve.Conclusion:Transcatheter closure with PDA occluder is feassible,safe and effective for RSVA.
