BACKGROUND: There has been no report observing the LV function of Konno incision. We examined the outcomes of the Konno operations over 20 years.
METHODS: We investigated 63 Konno operations with mechanical valves performed from 1984. This study aimed to evaluate the effects of Konno incision including LV function changes and the long-term outcomes of patient survival and reoperation rate (RVOT and LVOT complications).
RESULTS: The postoperative follow-up period was 20.6 ± 6.2 years. Early death occurred in 1 case and late death occurred in 9 cases. The cumulative survival rate was 89.6, 87.5, and 84.5% in the 5th, 10th, and 20th follow-up years. Five patients required reoperation for the aortic valve. The recurrence avoidance rate for LVOT reoperation was 96.6, 94.7, and 92% in the 5th, 10th, and 20th follow-up years of the Konno operation. Konno incision did not show significant decline in postoperative LV ejection fraction. (Pre, 62% vs 20 years later, 58%; P = 0.052.) There were no cases requiring intervention at the event of ventricular arrhythmia, but 13 cases were Complete Right bundle branch block, and 11 cases were Left bundle branch block.
CONCLUSIONS: The survival rate associated with Konno operation throughout 20 years was excellent. Konno incision can secure sufficient LV outflow tract and is a safe treatment for complex LVOTO without deteriorating LV ejection fraction.
