Abstract

Objective Children undergoing Ross operation were expected to have longer autograft, but shorter homograft durability compared with adults. In order to define the outcome in the second decade after Ross operation in children, a nationwide review of 23 years of experience was undertaken.

Methods 305 children underwent Ross operation in 11 paediatric units between 1990 and 2012. Age at surgery was 9.4±5.7 years, indication aortic stenosis in 103 patients, regurgitation in 109 and mixed lesion in 93. 116 (38%) patients had prior procedures. Root replacement was performed in 201 patients, inclusion cylinder in 14, subcoronary grafting in 17 and Ross–Konno in 73.

Results There were 10 (3.3%) hospital and 12 late deaths (median follow-up 8.7 years). Survival was 93±2% and 89±3% and freedom from any reoperation was 76±3% and 67±6% at 10 and 15 years. 34 children had autograft 37 reoperations (25 replacement, 12 repair): three required transplantation after reoperation. Freedom from autograft reoperation was 86±3% and 75±6% at 10 and 15 years. 32 children had right heart redo procedures, and only 25 (78%) conduit replacements (15-year freedom from replacement, 89±4%). Prior operation (p=0.031), subcoronary implant (p=0.025) and concomitant surgical procedure (p=0.004) were risk factors for left heart reoperation, while infant age (p=0.015) was for right heart. The majority (87%) of late survivors were in NYHA class I, 68% free from medication and six women had pregnancies.

Conclusions Despite low hospital risk and satisfactory late survival, paediatric Ross operation bears substantial valve-related morbidity in the first two decades. Contrary to expectation, autograft reoperation is more common than homograft.
