title: Diagnosis and surgical correction of cor triatriatum in an adult: combined use of transesophageal echocardiography and catheterization.
abstract: This is an unusual case of a 37-year-old male whose initial presentation to medical care was for dyspnea. A transthoracic echocardiogram was suspicious for cor triatriatum, which was confirmed by transesophageal echocardiography. Since the resting transmembrane gradient was low, a cardiac catheterization with exercise hemodynamics was performed and demonstrated a marked increase in pulmonary capillary wedge and pulmonary artery pressures. The cor triatriatum was successfully resected at surgery. We have reviewed the English literature and find this to be a unique approach to diagnosis and management.
