Replacement procedures in patients with aortic root dilatation became more important with increasing information about the dynamic nature and physiology of the aortic root. Especially, valve sparing aortic root replacement and reimplantation procedures are more preferred in normal valve function. In our study, we evaluated early and mid term results in patient with valve sparing aortic root reimplantation.
29 patients with aortic root aneurysm were included to our study between April 2009 and December 2012. Avarage age was 58.3±12.8 (30-79) years. 21 (72.5%) patient were male and 8 (27.5%) patients were famale. David V procedure was performed in patients. Native aortic valve was kept in 19 patient because of normal structure and function. Aortic valve was repaired in 9 patients. Stentless bioprosthetic aortic valve was replaced to an elderly patient due to degenerative aortic valve regurgitation. In addition that coronary artery bypass grafting was performed in 9 patients and mitral valve repair was performed in one patient.
There was no operative mortality. One patient died due to renal and respiratory failure and one patient died due to myocardial stunning in early term. Aortic valve function is normally in 26 (89.6%)patients (≤1°regurgitation) in the early postoperative period. 2nd degree of aortic regurgitation was detected in 3 (10.4%) patients. There was no mortality postoperative late period. Aortic reoperation was not required due to procedural failure in the late period.
Valve sparing aortic root reimplantation improves quality of life in patients. Patients are kept from complication of mechanical valve and anticoagulant therapy. If necessary to replace the aortic valve in elderly patient, the stentless biological aortic valve can be used in these patients. So left ventricular outflow tract gradient can be reduced and left ventricular function can be kept. Therefore may avoided from complications of anticoagulant therapy in these patients.
