Value of echocardiography in transcatheter closure of ruptured sinus of Valsalva aneurysm / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the value of echocardiography in transcatheter closure of ruptured sinus of Valsalva aneurysm(TC-RSVA).Methods TC-RSVA was attempted in 11 patients.The location,shape,size of defects and its relationship with the neighbor structures were revealed before the procedure.Then the deployment of occluder was monitored during the procedure,and the effectiveness was observed in the follow-up.Results Eleven patients were diagnosed as the isolated RSVA by echocardiography.The size of defects was 2 - 13 mm estimated by echo.The procedures were successful in all patients.Usually the Amplatzer duct occluders were chosen to be 1 to 5 mm larger than the size of defects.Three patients had mild residual shunt during the procedure,which all dispeared in the first month of follow-up,but one of them demonstrated recurrent mild residual shunt in the 32nd month of follow-up.There was no aggravating aortic regurgitation in the follow-up.Conclusions TC-RSVA is relatively safe and effective.Observation of long-term effectiveness is still necessary.Echocardiagraphy plays an important role in TC-RSVA.
