[Ventricular septal rupture after blunt chest trauma].
METHODS
Case 1: a 20-year-old previously healthy man sustained multiple nonvascular injuries without visible chest trauma in a car accident. Four days later a loud systolic murmur was heard over the heart. Case 2: a 21-year-old man similarly sustained in a car accident multiple injuries without visible chest involvement but causing haemorrhagic shock. A loud systolic heart murmur was heard and after shock treatment he developed left heart failure requiring catecholamine infusions.


METHODS
Echocardiography demonstrated posttraumatic ventricular septal rupture in both patients. Cardiac catheterisation revealed a small left to right (1 : 1.6) shunt in case 1, and a large one, 1 : 3, with markedly elevated pulmonary artery pressure in case 2.


RESULTS
In case 1, no treatment was needed as the intracardiac shunt was small and there were no symptoms. But in case 2 the large shunt with pulmonary hypertension required operative closure with a Dacron patch 2 days after the diagnosis had been established.


CONCLUSIONS
Ventricular septal rupture after blunt trauma to the chest is a rare occurrence. Even though in general the prognosis is good, a large intracardiac shunt may require early surgical repair.
