Fulltext PDFIntroduction: Cor triatriatum is a rare congenital cardiac anomaly in which a fibro muscular membrane divides the left (sinistrum) or the right (dextrum) atria into a total of 3 chambers and hence ‘triatriatum’. We present a case of 60-year-old female with cor triatriatum sinister (CTS) with concomitant coronary artery disease (CAD) who underwent CABG and successful repair of CTS.
Case Description: A 60-year-old Caucasian woman with h/o dyslipidemia presented with progressive dyspnea and fatigue for 1 year. Physical examination was unremarkable. Transthoracic echocardiogram showed an EF of 65%, moderately dilated Left Atrium (LA) and no valvular abnormalities. However, a diastolic gradient was present across a structurally normal mitral valve, hence CTS was suspected. Findings of CTS were confirmed by a TEE. Cardiac catheterization prior to surgery showed two-vessel disease. On surgical exploration, a 3.9 cm × 3.1 cm × 0.1 cm membrane was seen in the LA with a nickel sized opening. After CABG and removal of membrane, her symptoms improved.
Discussion: Cor triatriatum is a rare congenital abnormality, found in 0.1% of diagnosed congenital cardiac malformations. Mal-incorporation of the common pulmonary vein into the LA is the most common cause of CTS, creating two chambers that may or may not be separated by an opening. CTS is usually diagnosed in the pediatric age group, causing LA outflow obstruction mimicking mitral stenosis, or due to its association with other cardiac malformations. CTS rarely remains asymptomatic till adulthood. Our patient presented at 60 years with exertional dyspnea, diagnosed with CTS with CAD which is very rare, and not previously reported.
