Key result
Right ventricular outflow tract reconstruction using ePTFE valved patches with a bulging sinus achieved 87.9% freedom from reoperation at 15 years, with no patch-related deaths.
Why the study?
Late outcomes of right ventricular outflow tract reconstruction using expanded polytetrafluoroethylene valved patches with bulging sinuses and a fan-shaped valve required evaluation.
Does RVOT reconstruction using ePTFE valved patches with a bulging sinus provide satisfactory long-term freedom from reoperation and hemodynamic outcomes in patients requiring RVOT reconstruction?
Observational (n=690)
Does RVOT reconstruction using ePTFE valved patches with a bulging sinus provide satisfactory long-term freedom from reoperation and hemodynamic outcomes in patients requiring RVOT reconstruction?
RVOT reconstruction using ePTFE valved patches with a bulging sinus demonstrates excellent long-term freedom from reoperation and favorable hemodynamics across a wide age range.
No takes yet. Share an insight, caveat, or question.
May support ePTFE patches for RVOT reconstruction; extends observational durability data while leaving randomized confirmation open.
Miyazaki et al. (2019) conducted an observational in Right ventricular outflow tract reconstruction (n=690). Expanded polytetrafluoroethylene (ePTFE) valved patches with bulging sinuses and a fan-shaped valve was evaluated on Freedom from reoperation at 15 years. Right ventricular outflow tract reconstruction using ePTFE valved patches with a bulging sinus achieved 87.9% freedom from reoperation at 15 years, with no patch-related deaths.
