Simplified art of balloon pulmonary valvuloplasty: Does the presence of mild supravalvular pulmonary stenosis preclude successful balloon pulmonary valvuloplasty?

Abstract

We present a case of successful balloon pulmonary valvuloplasty (BPV) in a 37-year-old female with severe valvular pulmonary stenosis with peak gradient of 82 mmHg with history of exertional presyncope. The crux of our case was that patient also had associated mild supravalvular pulmonary stenosis which did not preclude a successful BPV outcome. The patient had rare Bombay negative blood group, and the requisite units were not available across all the blood banks in the state to subject the patient for surgical correction. Although the art of BPV is dying among budding young interventionists, this simple procedure is as good as surgical pulmonary valvotomy so far as the immediate and late outcome is concerned and the presence of mild supravalvular pulmonary stenosis does not preclude a successful outcome. Our case is a unique illustration of feasibility of successful balloon pulmonary valvuloplasty in the presence of associated mild supravalvular stenosis.
