title: Two-dimensional echocardiographic recognition of complications of cardiac invasive procedures.
abstract: Two-dimensional echocardiography allowed prompt recognition of a major complication of a cardiac invasive procedure in 6 patients. In 5 cases, a preinvasive echocardiographic study was available for comparison. In 1 patient with perforation of the ventricular septum by a temporary pacemaker, the catheter was visualized as it passed through the ventricular septum, with the tip located against the left ventricular posterolateral wall. In another patient, the intimal flap caused by aortic dissection after left-sided heart catheterization was clearly visualized. In 2 patients with hemopericardium secondary to cardiac perforation during right-sided cardiac catheterization, 2-dimensional echocardiography revealed pericardial effusion not noted in studies performed before the invasive procedure. Two patients in whom hemopericardium occurred from injury by the pericardiocentesis needle also were studied by 2-dimensional echocardiography. Postpericardiocentesis images revealed new intrapericardial abnormalities (a thrombus-like mass and fibrinous strands) not present in the echocardiographic studies performed before pericardiocentesis. Real-time 2-dimensional echocardiography appears to be a good tool in the recognition of the emergencies secondary to cardiac invasive procedures.
