Aortic Root Distortion and Aortic Insufficiency During Balloon Angioplasty of the Right Ventricular Outflow Tract Prior to Transcatheter Pulmonary Valve Replacement
Key result
Aortic root distortion or insufficiency was noted in 33% (6/18) of patients during RVOT balloon angioplasty, with no progression of aortic insufficiency observed post-TPV implantation.
Why the study?
Does RVOT balloon angioplasty prior to TPV implantation cause significant aortic root distortion or aortic insufficiency?
Population
118 patients undergoing catheterization with intent for transcatheter pulmonary valve implant, mean age 24.5…

Implication
AD/AI during pre-TPV RVOT ballooning may occur; retrospective data leaves open incidence and clinical relevance.

118 patients (mean age 24.5 years) undergoing catheterization with intent for transcatheter pulmonary valve implantation.

Exposure
RVOT balloon angioplasty with simultaneous aortography prior to TPV implantation

Outcome
Aortic root distortion (AD) and/or aortic valve insufficiency (AI) during balloon angioplastysurrogate
Aortic root distortion and aortic insufficiency are common during RVOT balloon angioplasty prior to TPV implantation but appear benign in most cases, though careful evaluation is needed in certain anatomic subtypes.
Cite This Study
Torres et al. (2016) conducted an observational in Transcatheter pulmonary valve replacement candidates (n=118). Balloon angioplasty of the right ventricular outflow tract was evaluated on Aortic root distortion (AD) and/or aortic valve insufficiency (AI). Aortic root distortion or insufficiency was noted in 33% (6/18) of patients during RVOT balloon angioplasty, with no progression of aortic insufficiency observed post-TPV implantation.
