RESUMO
Two cases are described wherein right atrial compression from a dilated and elongated ascending aorta caused intermittent positional hypoxia. Extrinsic compression of the right atrium caused shunting though a patent foramen ovale.

Left ventricular pseudoaneurysms are a rare complication of myocardial rupture. The diagnosis is paramount because of the propensity of pseudoaneurysms to rupture. Color flow imaging has been reported to be an aid in the diagnosis of pseudoaneurysms. We recently studied a patient with a myocardial infarction who developed a left ventricular pseudoaneurysm. Diagnosis was made by two-dimensional imaging with color flow imaging. He subsequently had a repair procedure with a gortex graft. One week after repair, repeat echocardiography with color flow imaging showed flow into the aneurysmal sac at multiple sites, consistent with recurrence of the pseudoaneurysm. Echocardiography with color flow imaging provides a safe noninvasive diagnostic tool for evaluating pseudoaneurysms preoperatively and in assessing the competency of the repair postoperatively.
