Pulmonary valve replacement late after repair of tetralogy of fallot

Clinical Outcomes of Surgical Pulmonary Valve Replacement After Repair of Tetralogy of Fallot and Potential Prognostic Value of Preoperative Cardiopulmonary Exercise Testing

“…When the deleterious effects of pulmonary regurgitation were more fully appreciated circa 2000, asymptomatic patients with pulmonary regurgitation were considered for PVR, including patients with lower or declining peak V . Our data confirm that surgical PVR is a low-risk operation, 10,14,[17][18][19][20][21][22][23][24][25][26][27][28][29][30] despite the fact that symptomatic patients and patients with multiple previous sternotomies were included in our report. All 5 patients who died early, however, died of right heart failure, suggesting that despite our modified, proactive approach for PVR, we still operate too late in some cases.…”

“…In contrast to improvement in NYHA class, there was no significant change in peak V . o 2 at a median follow-up of 3.0 years (1.7-4.7 years) from the index PVR (baseline versus latest CPEX, 21 …”

Outcomes of prenatally diagnosed tetralogy of Fallot: Implications for valve-sparing repair versus transannular patch

“…Interestingly, both interventional groups in follow-up revealed significant pulmonary insufficiency (71% of the valve-sparing repair group and 92% of the transannular patch repair group; P=0.69). While other studies have found significantly reduced rates of pulmonary insufficiency in the valve-sparing procedure (1,10,14), our study was not powered to illustrate this difference. Furthermore, a greater understanding of the natural history of pulmonary insufficiency and its deleterious sequelae is likely to be of value.…”

“…Factors associated with optimal surgical repair Previous studies have suggested that sparing the PV represents the best surgical outcome for patients with tetralogy of Fallot (1,10,14). The focus of our study was to determine echocardiographic factors associated with postnatal outcome.…”
