Surgical anatomy of double-outlet right ventricle—A reappraisal

摘要: Abstract In light of the recent developments in surgical treatment double-outlet right ventricle, anatomic observations on this lesion were reevaluated. For review, ventricle was diagnosed when more than half both arterial valves connected to same although appreciating reasons for using, a clinical context, “90% rule” rather “50% used review. Although ventriculo-arterial connection can exist with any segmental combination, most often it is found setting usually arranged atrial chambers (solitus) and atrioventricular concordance. Categorization subset then done basis relationships trunks. Three main groups stand out: Intertwining trunks “normally related” valves, parallel trunks, but aortic valve side or left side. These groupings give information concerning site ventricular septal defect, which group may be perimembranous, muscular doubly committed subarterial. Infundibular morphology also variable, proximity roof defect largely determined by extent ventriculo-infundibular fold.
