Abstract/OtherAbstract:
Background: Cardiac pheochromocytoma is extremely rare. Previous papers usually are reports of a single case. Transthoracic echocardiography (TTE) offers a useful option, but the features of cardiac pheochromocytoma on TTE have not been favorably reported. In this study, the findings of cardiac pheochromocytoma on TTE in nine cases were presented. Methods: TTE images (especially two-dimensional ultrasound) of nine patients with cardiac pheochromocytomas were analyzed retrospectively and compared with the findings from surgery. Results: Among the nine patients with cardiac pheochromocytomas identified in Peking Union Medical College Hospital (PUMCH) clinical and echocardiographic database, TTE identified one cardiac tumor in seven cases (77.8%), two cardiac tumors in one case (11.1%), and a false-negative result in another (11.1%). Cardiac pheochromocytomas were usually located on the base of the heart, near the origin of great arteries. The tumors were usually round or ovoid, ranging from 1.4 cm to 7.7 cm in diameter, with homogeneous and moderate echoes and low activity. They could press or invade surrounding cardiac structures and influence hemodynamics. In this study the majority of cardiac pheochromocytoma seemed marginated and appeared to be encapsulated on TTE. Apical four-chamber view and parasternal short-axis view of the aortic valve were most effective in identifying cardiac pheochromocytomas. The findings on TTE were similar to those from surgical procedures. Conclusion: Cardiac pheochromocytomas presented characteristic TTE appearances in aspect of location, size, texture, and shape of tumors. Understanding of these characteristics on TTE can help correctly recognize this extremely rare disease. (Echocardiography ****;**:1-5).
