Objectives: The aim of the study was to evaluate operative and long-term results of valve-sparing aortic root surgery in acute type A dissection. The repair consisted of selective replacement of all dissected and pathological sinuses.
Methods: Forty-six patients (mean age 62 ± 14; range 29-88 years, 3 with Marfan syndrome), operated on between August 2001 and July 2011 due to acute type A aortic dissection, underwent valve-sparing root repair, resulting in a valve preservation rate of 56% in acute aortic dissection surgery involving the aortic root.
Valve-sparing aortic root repair without down-sizing of the annulus.

Objectives: The study was conducted to evaluate the intermediate results after patient-tailored aortic root repair with replacement of isolated sinuses adjusted to the existing aortic annulus diameter rather than annulus downsizing.
Methods: Between 2000 and 2009, 236 patients with aortic root disease underwent patient-tailored restoration of the aortic root according to its anatomopathologic condition with repair of 1, 2, or all 3 sinuses in 73, 94, and 69 patients, respectively. Concomitant cusp repair was performed in 106 patients.
Objective: Biological aortic valve conduits are rarely used because of the concern that possible structural valve deterioration would require complete conduit replacement in a technically demanding operation. The aim of the study was to evaluate the 10-year experience with complete aortic-root replacement using a modified composite graft in which biological valve prosthesis was located inside the vascular graft allowing its replacement within the tube and leaving the coronary ostia untouched.
Methods: Self-assembled composite grafts as described have been used in our clinic since 1998 as the standard for patients needing a biological aortic-root replacement.
