Pulmonary valve stenosis (PS) could be treated efficiently by balloon valvuloplasty. Severe PS with high gradient(PG) or moderate symptomatic PS are considered for valvuloplasty. The success of valvuloplasty is estimated by reduction of PG. Right ventricular (RV) affection with PS could occur even with non-severe PG. Markers of myocardial damage due to increased afterload such as troponin are hypothesized to increase with severe RV strain.
