First experience with sildenafil after Fontan operation: short-term outcomes

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Pharmacology

Background:

• Retrospective study on single ventricle physiology post-Fontan operation.
• Investigating oral sildenafil as monotherapy in pediatric patients.
• Focus on extracardiac conduit Fontan procedures.

Purpose of the Study:

• To determine the effect of oral sildenafil on postoperative outcomes.
• To evaluate sildenafil's impact on hemodynamic parameters.
• To assess the safety and efficacy of sildenafil monotherapy.

Main Methods:

• Retrospective analysis of 30 pediatric patients (2008-2012).
• Sildenafil group (13 patients) received specific dosage and timing.
• Control group (17 patients) received no other vasodilators.

Main Results:

• Sildenafil group showed significantly lower drainage loss (P<0.001).
• Improved hemodynamic parameters including lower mean pulmonary artery pressure (mPAP) (P<0.0001).
• Reduced inotropic score and intubation time, with no reported complications.

Conclusions:

• Sildenafil demonstrates positive effectiveness in postoperative Fontan operation.
• Oral sildenafil monotherapy is a potentially beneficial treatment option.
• Further research may support sildenafil use in single ventricle patients.
