Coronéo extra-aortic annuloplasty ring could stabilize even the pulmonary autograft annulus in a Ross operation


Vojacek, Jan; Spatenka, Jaroslav; Holubec, Tomas; Zacek, Pavel (2013). Coronéo extra-aortic annuloplasty ring could stabilize even the pulmonary autograft annulus in a Ross operation. European Journal of Cardio-Thoracic Surgery, 43(2):431-433.

Abstract

The Ross procedure is an alternative technique to mechanical prosthesis and recent evidence suggests that it is associated with improved long-term survival and quality of life. However, late pulmonary autograft failure can occur more frequently in patients with significant dilation of the aortic annulus. Here, we present a technical modification of the Ross procedure--a case report of a patient who underwent a Ross procedure in which the gross dilation of the aortic annulus was reduced by implantation of an extra-aortic Coronéo annuloplasty ring. Before discharge, we performed a multidetector computed tomography (MDCT) to verify the effect of extra-aortic annuloplasty on the geometry of the neoaortic root and particularly on the dimension of the aortic annulus. The result of the MDCT demonstrated that the ring sits in the optimal position at the level of aortoventricular base and that aortic annulus is significantly reduced.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
