ABSTRACT
BACKGROUND: Myxomas arising from the eustachian valve are exceedingly rare. CASE REPORT: A 72-year-old Jamaican-Chinese woman was evaluated for worsening dyspnea. The 2-dimensional and real time 3-dimensional transesophageal echocardiogram showed a 75 mm length × 44 mm width, multilobulated, mobile mass arising from the eustachian valve occupying the entire right atrial and right ventricular cavities extending into the coronary sinus, right ventricular outflow tract, and proximal inferior vena cava. The patient underwent successful resection of the mass and replacement of the tricuspid valve. Histopathologic examination confirmed the diagnosis of atrial myxoma. CONCLUSIONS: This is the largest myxoma found on a Eustachian valve.
ABSTRACT
Pseudoaneurysms in the ascending aorta most commonly occur as a complication of surgical procedures at this site. They have also been reported in association with trauma, infection, aortitis, and other disorders. Pseudoaneurysm formation in the descending aorta or arch may occur as a result of penetrating ulcers in the presence of severe atherosclerotic plaque. Pseudoaneurysm as a result of atherosclerotic disease has only rarely been noted in the ascending aorta, where complex plaque is less common. We report here the finding with transesophageal echocardiography of a pseudoaneurysm in the ascending aorta as a result of atherosclerotic disease and penetrating ulcer.
