The Damus-Stansel-Kaye procedure. Should the aortic valve or subaortic valve region be closed?

摘要: Two patients (one with transposition of the great arteries and another Taussig-Bing anomaly) underwent Damus-Stansel-Kaye procedure (Group I). Significant aortic valve insufficiency developed postoperatively in both patients. In contrast, seven a univentricular heart subaortic stenosis from variety reasons creation an aortopulmonary window II), very similar to proximal main pulmonary artery–aortic root anastomosis procedure. Aortic had not after up 7 years follow-up this group (average 43 months). Postoperative angiograms suggest that incompetence Group I may have been caused by prolapse valve. The valvular structures are subjected high systolic pressures face dilated, low-pressure right ventricle. distortion contributed, as well.
