摘要：We encountered a pre-operative patient with hypertrophic cardiomyopathy who needed a careful evaluation of heart failure by Doppler echocardiography. On echocardiographic examination, mitral inflow showed an abnormal relaxation pattern, suggesting normal left atrial pressure. However the pulmonary capillary wedge pressure by a Swan-Ganz catheter was elevated. In echocardiographic parameters, mitral E velocity to mitral annular E velocity ratio(E/E') suggested high left atrial pressure. Doppler echocardiographic evaluation of heart failure needs to be performed carefully, especially in patients with hypertrophic cardiomyopathy and advanced diastolic left ventricular relaxation.
