Surgical pulmonary valve replacement: a benchmark for outcomes comparisons

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Medical Devices

Background:

• Right heart obstructive lesions often lead to pulmonary valve (PV) dysfunction.
• Surgical pulmonary valve/conduit replacement (PVR) has been the standard treatment.
• Catheter-based interventions are emerging as alternatives for PV dysfunction.

Purpose of the Study:

• To evaluate the outcomes of surgical PVR in a pediatric population.
• To establish contemporary benchmark data for comparison with emerging catheter-based technologies.

Main Methods:

• Retrospective review of 148 PVR procedures between July 1995 and December 2010.
• Inclusion criteria: age ≥5 years and weight ≥30 kg, excluding complex concomitant procedures.
• Focus on patients with prior interventions for conditions like tetralogy of Fallot and pulmonary atresia.

Main Results:

• No hospital deaths; low intensive care unit and hospital length of stay.
• Excellent freedom from PV reintervention at 1, 3, and 5 years (99%, 99%, 94%).
• Younger age (<13 years) and smaller valve size were associated with increased reintervention risk.

Conclusions:

• Surgical PVR demonstrates safety with low in-hospital and midterm mortality.
• Reoperation rates are low, providing a valuable benchmark for treatment strategy comparisons.
• Outcomes support surgical PVR as a viable option for pediatric patients with PV dysfunction.
