Ruptured left ventricular pseudoaneurysm penetrating into the left pleural cavity.
We experienced a rare case of ruptured left ventricular pseudoaneurysm penetrating into the left pleural cavity. A 77-year-old woman was first diagnosed with unstable angina due to sudden chest pain onset and abnormal electrocardiographic findings. In 2 days, massive left pleural effusion was recognized by chest X-ray, though subsequent computed tomographic scans did not show any aortic pathology. We observed her with left thoracentesis alone. Two days later, cardiac arrest suddenly occurred and emergency surgery was undertaken after resuscitation by percutaneous cardiopulmonary support. In surgery, a moderate amount of intrapericardial hematoma caused by rupture of a left ventricular pseudoaneurysm penetrating into the left pleural cavity was found and successfully repaired. This rare rupture of a left ventricular pseudoaneurysm penetrating into the left pleural cavity generated massive hemo-hydrothorax.
