Operative interventions over the years have evolved because the intervening outcomes proved to be unsatisfactory. The resection for subvalvar aortic stenosis has progressed from a fibrous \u201cmembrane\u201d resection to a more extensive fibromuscular resection. Operative solutions for valvar aortic stenosis and regurgitation have resulted in operative interventions that depend on simple commissurotomy, leaflet extensions, prosthetic mechanical valve replacement, biologic valve replacement, including the pulmonary autograft, and operations to treat aortic annular stenosis. Although there are enthusiastic proponents for all of these strategies, the fact remains that none have proven to be curative; patients can expect to undergo further procedures during their lifetimes. The short- and mid-term solutions to these left ventricular outflow tract abnormalities have improved based on operations that have been attended by increasing operative complexity. The purpose of this review is to chronicle the operative steps of the Ross operation, the Konno\u2013Rastan operation, the modified Konno operation, the Ross\u2013Konno operation, and the modified Ross\u2013Konno operation.<\/jats:p>","DOI":"10.1017\/s1047951114002042","type":"journal-article","created":{"date-parts":[[2014,12,29]],"date-time":"2014-12-29T11:28:05Z","timestamp":1419852485000},"page":"1121-1133","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":13,"title":["The
