The authors report the case of an acquired left ventricle-right atrial comm
unication after open chest trauma. The initial clinical presentation was a
haemothorax and haemopericardium responding well to emergency surgical drai
nage. Secondarily, a systolic murmur suggesting a ventricular septal defect
and signs of right heart failure were observed.
Colour Doppler echocardiography led to the diagnosis of a left ventricle-ri
ght atrial communication associated with tricuspid regurgitation with dilat
ation of the right heart chambers and pulmonary hypertension. At surgery, a
defect in the membranous interventricular septum was confirmed with ruptur
e of the septal tricuspid leaflet causing tricuspid regurgitation. The surg
eon closed the defect with a patch and performed a De Vega tricuspid valvul
oplasty. The postoperative outcome was uneventful.
