Abstract:
Ninety-nine patients underwent valve sparing aortic root replacement, mostly using reimplantation technique. Mean age was 56.1±13.4 years. Indication of this type of operation was extended to patients with significant aortic regurgitation (AR) accompanied by sinus Valsalva diameter more than 40 mm. Bicuspid valve presented in 17 patients. The proportion of severe AR was 55%. Valve plasty technique included central plication (n=61) and pericardial patch (n=7). Operative mortality was 1%. AR grade at discharge was none or trivial in 87 patients (88%). Five-year survival rate was 96%. There were 5 reoperation and 2 patients underwent re-repair. Five-year reoperation free rate was 96%.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
