Early Morbidity and Mortality Within 30 days of hospitalization, morbidity and mortality after Bentall procedure are associated with complications stemming from cardiac arrhythmia, pneumonia, acute respiratory distress syndrome (ARDS), sepsis, graft infection, wound infection, neurologic/ cerebrovascular accident and stroke, hemorrhage/ bleeding, myocardial infarction, pericardial effusion ...
Dr. Juan C. Parodi introduced the minimally-invasive endovascular aneurysm repair (EVAR) to the world and performed the first successful endovascular repair of an abdominal aortic aneurysm on 7 September 1990 in Buenos Aires on a friend of Carlos Menem, the then President of Argentina. The first device was simple, according to Parodi: "It was a ...
Open surgery typically involves exposure of the dilated portion of the aorta and insertion of a synthetic (Dacron or Gore-Tex) graft (tube). Once the graft is sewn into the proximal (toward the patient's head - and more specifically, towards their aortic valve) and distal (toward the patient's foot) portions of the aorta, the aneurysmal sac is ...
The graft is then sutured to the cusp insertion lines. Some surgeons combine this procedure with an annuloplasty. [12] [21] For the procedure according to Tirone David, [17] the aortic valve is mobilized even further from the surrounding tissues. The avascular graft is then positioned around the valve, and the valve is fixed inside the graft ...
Common features of both techniques of the replacement process are the clamping of the aorta and the use of a length of Dacron tube (also known as an "aortic graft"), typically 5 cm, to constrict the aortic root to the normal diameter, while the patient is cooled to 20°C and placed on life support. The procedure typically takes 4 to 6 hours in ...
Advisers to the U.S. Food and Drug Administration on Tuesday backed an approval for Abbott Laboratories' heart valve repair device that is designed for patients who are at risk of complications or ...
If the left sided outflow root needs to be enlarged to fit the pulmonary autograft, the procedure is called Ross-Konno. [3] An alternative to a pulmonary homograft is the stentless xenograft roots such as the Freestyle Porcine Aortic Root by Medtronic. [2] [12] An external Dacron graft can be used to reinforce the pulmonary autograft. [2]
Acute graft occlusion is the occlusion (blockage) of a vascular bypass graft shortly after the bypass is performed. Its causes, which are distinct from those of chronic graft occlusion , include technical failure (e.g. anastomotic stricture, incomplete valve lysis in non-reversed vein) and thrombosis.
