Surgical treatment of pulmonic stenosis in dogs under cardiopulmonary bypass: outcome in nine dogs

Abstract: Expanded polytetrafluoroethylene patch grafting of the right ventricular outflow tract for treatment of severe pulmonic stenosis in dogs is feasible and can be an effective method to reduce the severity of right ventricular outflow tract obstruction.

“…Right heart function is challenging to determine with echocardiography due to the complex geometry of the right ventricle 35,36 ; however, the presence of R-CHF is suggestive of secondary right-sided myocardial F I G U R E 3 Kaplan-Meier curves to explore the difference in median survival time between dogs treated with sildenafil and those not treated with sildenafil in dogs with bidirectional or right-to-left shunting patent ductus arteriosus (PDA) F I G U R E 4 Kaplan-Meier curves to explore the difference in median survival time between dogs receiving sildenafil dose <3 mg/kg/d and those receiving sildenafil dose ≥3 mg/kg/d in dogs with bidirectional or right-to-left shunting patent ductus arteriosus (PDA) F I G U R E 5 Kaplan-Meier curves to explore the difference in median survival time between dogs in right-sided congestive heart failure (R-CHF) compared to those without R-CHF in dogs with bidirectional or right-to-left shunting patent ductus arteriosus (PDA) dysfunction in these animals (although the impact of concurrent rightsided congenital disease, such as TVD, cannot be excluded). The development of R-CHF is also a poor prognostic indicator in dogs with pulmonic stenosis (rather than PH), [37][38][39] and worse outcomes are similarly reported in people with R-CHF due to Eisenmenger's physiology. 40 Interestingly, in this study, median survival time in dogs with bidirectional and right-to-left PDA without R-CHF at the time of presentation was greater than 5 years, suggesting that dogs without R-CHF can have a good prognosis despite having reverse PDA.…”

“…Moreover, CPB is considered a high morbidity and mortality approach, with several intraoperative and postoperative complications (eg, hemorrhage, embolism, infection) that could lead to patient death. 31 However, the use of CPB in dogs has increased considerably in the last 10 years, [32][33][34][35][36][37] as has safety, because of improvement in surgical and perfusion techniques, specialized equipment, and operator expertise. Finally, our group had already started using CPB with success for surgical treatment of other cardiac diseases in dogs and therefore had experience with this technique.…”
