The Surgical Treatment Of Adult Bicuspid Aortic Valve Deformity

Objective:To summarize the clinical experience of using Retrograde Cor onary Sinus Perfusion in Beating Heart Surgery for treatment of Bicuspid-Aortic Valve Deformity.Method:35Bicuspid-Aortic Valve Deformity cases were treated from January2009to May2012in Guangxi Medical University, First Affiliate d Hospital, Department of Cardiothoracic Surgery. Traditional Hypothermic Non-Beating Heart Surgery and Retrograde Coronary Sinus Perfusion in Beating Heart Surgery were performed and the results were compared.Results:The operating duration, cardiopulmonary bypass duration and post-operative drainage volume of the two different groups were compared and the results had no statistical difference (P>0.05); Dopamine amount injected and post-operative ICU stay period were compared in the two groups and showed statistical difference (P<0.05).Beating Heart Surgery group did not present with ventricular fibrillation, whereas Non-Beating Heart Surgery group had10patients presenting with ventricular fibrillation requiring defibrillation.2patients died,1in Beating Heart Surgery group and1in Non-Beating Heart Surgery group. Non-Beating Heart Surgery group did not present any Low Cardiac Output Syndrome whereas Non-Beating Heart Surgery group presented2cases who were treated properly. Beating Heart Surgery group presented2 cases of renal dysfunction post-surgery whereas Non-Beating Heart Surgery had only1case but patients were promptly managed using dialysis.Discussion:Retrograde Coronary Sinus Perfusion in Beating Heart Surgery for treatment of adult Bicuspid-Aortic Valve Deformity has very good prognosis in protecting cardiac muscles and with some surgical techniques makes the surgery safer.
