Three-dimensional echocardiography can overcome the obstacle of the thebesian valve.

A 77-year-old woman presented with pulmonary edema 2 weeks after experiencing an acute inferior ST-segment–elevation myocardial infarction treated successfully with primary coronary angioplasty with bare metal stent implantation in the right coronary artery. On admission, she experienced marked dyspnea, and on physical examination, she had tachypnea, her peripheral pulse was irregular with an average rate of 86 bpm, her blood pressure was 152/77 mm Hg, she had elevated jugular vein pressure, her heart sounds were irregular and attenuated, and her breathing sounds were decreased bilaterally with crepitations. The rest of the physical examination was not revealing. The ECG …
