Abstract 16029: Twenty-Year Outcome After the Ross Operation in Neonates, Infants and Children: Results From the Italian Pediatric Ross Registry

Objective: To define current outcome after Ross operation in children a nation-wide multi-center study covering 22 years of experience was undertaken. Methods: Between 1990-2013, 305 (178 male) patients underwent the Ross operation in 11 Italian Pediatric Cardiac Surgery units. Age at surgery was 9.4±5.7 years (2 days-18 years). Indication was aortic stenosis with or without subaortic stenosis in 103 patients, regurgitation in 109 and mixed lesion in 93. One-hundred-sixteen (38%) patients had prior cardiac operations. Root replacement was performed in 201 patients, inclusion cylinder in 14, sub-coronary grafting in 17 and Ross/Konno in 73. Results: There were 10 (3.2%) hospital and 12 late deaths, during a median follow-up of 7 years (2 months-22 years). Survival was 93±2% and 85±8% and freedom from any reoperation was 75±3% and 42±10%, at 10 and 20 years respectively. Twenty-two of 34 (65%) left-heart-reoperations were autograft replacement, while 12 had repair. Three patients required heart transplantat...
