Re-operation of RVOT (table 3):
Re-operation of RVOT has been performed in 8 patients (7.8%). Mean time
before re-operation was 5.48 ± 5.04 years. Among these patients, 4
(3.9%) had PH failure. Four patients (3.9%) were re-operated of RVOT
without PH dysfunction: 1 patient for PH injury during pace maker
implantation and 3 patients for stenosis of the pulmonary artery
branches. Re-operation of the RVOT consisted in PH replacement with an
other PH in 5 patients, percutaneous transcatheter valve implantation in
pulmonary position (Edwards Lifesciences Sapien XT, Irvine, CA, USA) in
2 patients and 1 RV-PA conduit implantation. Surgical enlargement of the
branches of the pulmonary arteries was performed in 3 patients who
presented stenosis of the pulmonary artery branches. Freedom from
re-operation of PH during follow-up at 1, 5 and 10 years was
respectively 100%, 95.7% and 90.0% (Figure 1). Bentall procedures
were associated with PH replacement in 2 patients (1 ascending aorta
aneurysm, 1 ascending aorta wound during surgery).
