Cor triatriatum with Partial Anomalous Pulmonary Venous Connection: Role of Multimodal Imaging.

Both cor triatriatum (CorT) and partial anomalous pulmonary venous connection (PAPVC) come under the rare spectrum of congenital heart diseases. These entities may coexist in a patient or may appear independent of each other. The diagnosis is established routinely by echocardiography. Here, we describe the case of a 45-year-old female presenting with exertional dyspnea and palpitations. She was diagnosed to have CorT in the preoperative echocardiography; later, intraoperatively, transesophageal echocardiography revealed the additional presence of PAPVC with CorT. This case report highlights the limitations of echocardiographic findings in the patient and the importance of multimodal imaging techniques in such situations. [ABSTRACT FROM AUTHOR]
