Abstract
The Ross-Personalized External Aortic Root Support procedure is a surgical aortic valve replacement technique in which the autologous pulmonary valve is transposed in the aortic position to replace the malfunctioning aortic valve and a homograft is implanted in the pulmonary position. To prevent autograft dilatation, a Personalized External Aortic Root Support prosthesis is included in the proximal autograft anastomosis and wrapped around the ascending aorta. The aorta is transected transversely, the aortic valve is resected, and the coronary arteries are mobilized and cut out of the sinuses, leaving a rim. The pulmonary autograft is harvested by transecting the pulmonary artery and part of the right ventricular outflow tract. The autograft is approximated to the aortic root and inverted inside the ventricle. The proximal anastomosis is performed including the prosthesis between the aortic root and the autograft. The coronary buttons are threaded through appropriately positioned and sized holes in the prosthesis and reimplanted into the autograft. The ascending aorta is appropriately adapted and anastomosed with the distal autograft. When the patient is off cardiopulmonary bypass, the prosthesis can be closed longitudinally and is anchored to the distal aortic adventitia.
期刊介绍:
The Multimedia Manual of Cardio-Thoracic Surgery (MMCTS) is produced by The European Association for Cardio-Thoracic Surgery (EACTS). MMCTS is the world’s premier video-based educational resource for cardiovascular and thoracic surgeons; freely accessible - and essential - for all. MMCTS was launched more than ten years ago under the leadership of founding editor Professor Marko Turina. It was Professor Turina’s vision that the European Association for Cardio-Thoracic Surgery (EACTS), already the world-leader in CT surgery education, should take advantage of the Internet’s rapidly improving video publication capabilities and create a new step-by-step manual of surgical procedures. Professor Turina and EACTS agreed that the manual, MMCTS, should be freely accessible to all users, regardless of association membership status, nationality, or affiliation. MMCTS was self-published by EACTS for some years before being transferred to Oxford University Press, which hosted it until the end of 2016. In November 2016, the Manual returned home to EACTS and it has now relaunched in a completely new format. Since its birth in 2005, MMCTS has published some 400 detailed, video-based demonstrations of cardio-thoracic surgical procedures. Tutorials published prior to 2012 have been archived and we are working with the authors of these tutorials to update their work pending republication on the new site. Our mission is to make MMCTS the best online reference for cardio-thoracic surgeons – residents and experienced surgeons alike. Our aim is to include tutorials presenting procedures at both a fundamental and an advanced level. Truly innovative procedures are also included and are identified as such.
