Transesophageal two-dimensional echocardiography in the diagnosis of cor triatriatum in the adult

Abstract

Two adult patients with left ventricular inflow obstruction are presented. Conventional two-dimensional echocardiography had failed to yield a definite diagnosis, whereas transesophageal two-dimensional echocardiography clearly documented a membraneous echo structure within the left atrium, diagnostic of cor triatriatum. On the basis of the transesophageal echocardiographic findings, left heart catheterization and angiocardiography were not performed and both patients successfully underwent cardiac surgery.

Cor triatriatum sinistrum: Diagnosis by Doppler Echocardiography

“…6], 2-D echocardiography appears to be a reliable and accurate method to detect this malformation [4,7], In the past few years however, there have been a num ber of reports concerning the misdiagnosis of CTT by 2-D echocardiography stemming either from its confusion with supravalvular mitral ring or with ultrasonic artefacts [4,[7][8][9], Schluter et al [4] recommended the use of transesophageal 2-D echocardiography as a unique tool for the confident diagnosis of CTT in adults. Rumancik et al [10] reported the use of magnetic resonance imaging in the diagnosis of CTT.…”

“…In adults transesophageal 2-D echo has been suggested as the most accurate procedure in diagnosing and evaluating the morphology of CTT [4], Doppler echocardiography is a relatively new technique that has become an integral part of the cardiovascular ultra sound examination. The hemodynamic in formation provided by this technique is complementary to the tomographic anatomy depicted by the 2-D examination.…”

Adult Cor Triatriatum Presenting as Cardioembolic Stroke

“…Although the diagnosis is commonly suspected on transthoracic study, transesophageal echocardiography (TEE) is frequently needed to precisely define the anatomy of the membrane, and the degree of obstruction caused by this structure (13)(14)(15). The cardiac MDCT, a new and powerful non-invasive imaging modality, provides a comprehensive anatomic evaluation of cor triatriatum (15). It can help the clinician to see a distinct septum in the LA, to evaluate the size and number of fenestrations, and to identify associated congenital cardiovascular anomalies (16).…”

Echocardiographic Finding of Non-Obstructive Fibromuscular Band in Right Atrium

“…It leads to questions for further research, whether to call it Cortriatrium dexter or not? IT was an important and rare disease which was diagnosed accidentally [31][32][33][34][35][36][37][38][39][40][41].…”
