Surgical results of Konno and Ross procedures in children and Bentall and David procedures in adults

: The surgical management of complex aortic root lesions has developed over 3 decades both in pediatric and adults patients. To avoid permanent anticoagulation and prosthetic materials as much as possible, we had introduced Ross procedure as an alternative to Konno procedure in pediatric patients and David procedures in adults patients. We sought to evaluate the surgical results of Konno, Ross, Bentall and David procedures. The Konno procedure has excellent long term results and anticoagulation-related complication and endocarditis were major causes of re-operation. Ross procedure has excellent long term results, and autograft failure and right ventricular outflow tract (RVOT) obstruction were causes of re-opertion Bentall procedure is certainly effective and has excellent long term results. Pseudoaneurysmal formation in coronary reconstruction was a major cause of reoperation. David procedure is certainly an attractive option especially for young patients. Early result was satisfactory but durability of this operation should be reevaluated.
