Types of Cardiovascular Complication Congenital heart disease先心: the most frequent 1. Left to right shunting左向右分流型 1) Atrial septal defect(ASD)房缺: most common asymptomatic (most patients); pulmonary blood fow↑(eson≥2cm2)→ pulmonary hypertension- Eisenmenger's syndrome 2) Ventricular septal defect(VSD)室缺 tolerated(small lesion); left ventricular hypertrophy- pulmonary hypertension biventricular hypertrophy
