title: Right ventricular outflow tract obstruction by lymphoma: case series and review of the literature.
abstract: External compression of the right ventricular outflow tract (RVOT) by lymphoma is a rare clinical entity. We present a series of three adult patients with varying clinical presentations, in which RVOT compression by lymphoma was diagnosed using echocardiogram. Review of the literature identified a total of 13 prior cases of RVOT obstruction by lymphoma diagnosed with echocardiogram. We have summarized the clinical features and echocardiographic findings of this disorder, and comment on the role of echocardiography in diagnosis and follow-up.
