[Intraventricular thrombosis complicating peri-partum idiopathic myocardiopathy]

Ventricular thrombosis can complicate the development and worsen the prognosis in any case of hypokinetic dilated cardiomyopathy. In the present article, a study has been made of 6 reports of ventricular thrombosis selected out of 58 medical files on women with peri-partum idiopathic cardiomyopathy. Patient age ranged from 22 to 55 years. The clinical picture showed hypokinetic dilated cardiomyopathy, complicated by cardiac failure; with its onset during the last trimester of gestation or in the 6 months post-partum. In all patients, overall cardiac failure was observed, and in all cases the diagnosis of intracardiac thrombosis was made by echocardiography. In all 6 patients, a left ventricular apical thrombosis was detected. In 2 subjects, 2 and 3 left ventricular thrombi were respectively found. In 1 case, a left ventricular thrombosis was present. In another case, a right thrombosis associated with a left ventricular thrombosis was detected. Treatment was initiated with a combination of anticoagulants (heparin and K antivitamins), diuretic and vasodilatory treatment. The clinical outcome was favorable, with the disappearance of thrombi and signs of cardiac failure (between the 15th and 54th day). No embolic complication was observed. These findings clearly show the importance of prescribing an anticoagulant treatment as a preventive measure during PPICM. Even if severe embolic complications are a potential risk, anitcoagulant treatment can ensure a favorable outcome.
