Asymptomatic Cor Triatriatum Incidentally Revealed by Computed Tomography

Cor triatriatum: The utility of cardiovascular imaging

“…At least two previous cases (16,17) of cor triatriatum have been diagnosed incidentally using CT. Our case is unique in that it is the first report of 64-slice multislice detector computed angiography revealing cor triatriatum.…”

Adult Cor Triatriatum Presenting as Cardioembolic Stroke

“…The hemodynamics of the cor triatriatum is similar to that of mitral stenosis and the most common presenting symptoms of cor triatriatum in adults are dyspnea, hemoptysis, and orthopnea as a result of the obstructive function of the intra-atrial membrane (2). In almost all cases, it is diagnosed in childhood, whereas adult cases are very rare (3)(4)(5). In this report, we present an unusual case of cor triatriatum in a 55-year-old woman initially presenting with embolic cerebral infarction in whom the diagnosis was delayed until adulthood.…”

Coexistence of coronary cameral fistulae and cor triatriatum sinister in an elderly patient

“…Depending on the size of the opening in the membrane, the obstruction to left ventricular inflow can manifest clinically from infancy to late adulthood, with symptoms of pulmonary venous congestion that imitate mitral stenosis. In rare cases, patients with cor triatriatum may remain asymptomatic and be diagnosed incidentally, 7 whereas others may have late onset of symptoms, possibly related to fibrosis and calcification of the orifice in the anomalous membrane, or the development of mitral regurgitation or atrial fibrillation. 8 Importantly, in our patient with non-obstructive cor triatriatum, exertional dyspnoea was probably related to the development of significant mitral regurgitation and atrial fibrillation/flutter.…”
