Abstract:
Objective To review and summarize the experiences of transcatheter closure of left ventricular-right atrium communication,and discuss the feasibility of interventional therapy for this kind of cardiac abnormalitis.Methods 22 patients who suffered from left ventricular-right atrium communication underwent transcatheter interventional therapy with ventricular septal defect(VSD) occluder.The operating procedures were performed as like as the transcatheter closure of VSD:established the pathway from femoral artery to femoral vein through left ventricle,VSD,right atrium (or from left ventricle to right atrial through the communication) and inferior vena cava,then inserted the polysheath from femoral vein,introduced by the pathway to left ventricle,and implanted VSD occluder through the polysheath to close the shunt.Results The operation succeeded in 21 patients.The cardiac murmur was disappeared in all patients,and there was no residual shunt or aortic regurgitation that conformed by postoperative ventriculography and echocardiography in follow up phase,and the tricuspid regurgitation was lessened than preoperative.The operation abort in 1 patient because of aortic regurgitation after implanting occluder.Conclusions Transcatheter closure of left ventricular-right atrium communication is feasible as the selected occluder is accordant,and atrioventricular block,aortic regurgitation and tricuspid regurgitation can be avoided.
