title: [Clinical studies on cases of cardiovascular disease during pregnancy (author's transl)].
abstract: The long term follow up studies on cases of cardiovascular diseases during pregnancy or delivery were reviewed in 181 patients administrated in our clinic. The results as follows: 1. An incidence of patients with cardiovascular disease during pregnancy was 1.46 per cent as a whole, and there was increasing tendency in congenital heart disease. 2. An accidental heart failure during pregnancy was seen in 7.7 per cent and all cases with NYHA III grade had an incidence of 100 per cent. 3. The occurrence of toxicosis and SFD pregnancy were more frequently seen in group of heart disease than in controls. But, no difference was observed in spontaneous abortion or neonatal asphyxia. 4. 28 patients with Starr-Edwards prosthetic heart valves became pregnant in our clinic. In these pregnancies, 5 cases receiving with warfarin therapy resulted in 3 anomalies of new born and in 2 spontaneous abortion. So, the use of warfarin seemed to have the risk to the fetus. But omission of the anticoagulant therapy on the other hand, increased the danger of systemic embolization to the mother. 5. The follow up study by mail in some cases revealed that, as a general, pregnancy and delivery may aggravate the condition of patients, especially who had mitral heart failures.
