Abstract:
Objective To evaluate the value of echocardiography in investigation the failure of interventional therapy of VSDs and to increase the successful rate. Methods 15 cases with failure of VSD closure through interventional approach were undertaken measurement of major parameters of the defect on left ventriculography and then followed by Philips 5500 color Doppler US for repeated multi-direction tangential measuring of the size, morphologic change, relation with peripheral structure and individual valvular regurgitation. Results (1) Marginal membranous VSD 10 cases; membranance aneurysm 8 cases, ≥2 outlets 6 cases. Width of basal part of membranous aneurysm was 8 ～ 18 (10 ?2) mm with depth of 3 ～ 10 (6 ? 2) mm, distance from aortic valve was 0 ～ 6 (2 ? 1) mm and from tricuspid valve was 2 ～ 5 (2 ?1) mm; associated with slight tricuspid valvular regurgitation. Aortic valvular regurgitation 5 cases showed slight to mild amount and without membranous aneurysm occurred in 2 cases. (2) Intracristal VSD 5 cases showed the size of defect as 6 ～ 10 (7 ? 1) mm, with distances of 2 ～ 3 (1 ? 0.8) mm from pulmonary valve and 1 ～ 2 (1 ? 0.6) mm from aortic valve associated with slight regurgitation in 4 cases, slight tricuspid valvular regurgitation in 5 cases and aortic valvular prolapse in 4 cases. Conclusions Many factors can influence the direction tangential continuous scanning should be taken for accurate localization and measurement of VSD in order to select the very sight occludor providing high successful rate of occlusion and long term efficacy.
