Symptoms of pulmonary valve disease are bluish tint to the skin, chest pain, fainting, heart palpitations, unexplained fatigue, failure to thrive, difficulty breathing.
Disease statistical analysis in Russia on pulmonary valve disease gave the result as the spirometric parameters showed significant correlation with increasing New York Heart Association (NYHA) functional class (FC): forced vital capacity (FVC, r = −0.4*, p = 0.04), forced expiratory volume in one second (FEV1, r = −0.5*, p = 0.01), FEV1/FVC (r = −0.44*, p = 0.02), and with pulmonary venous congestion (PVC): FVC (r = −0.41*, p = 0.04) and FEV1 (r = −0.41*, p = 0.04).
