Case Reports
Cor triatriatum sinistrum presenting as cardioembolic stroke: an unusual cause of adolescent hemiparesis.
Cor triatriatum sinistrum is a rare congenital cardiac malformation, in which the left atrium (LA) is divided into two distinct chambers by a fibromuscular membrane. Classically, the proximal (upper or superior) chamber of the LA receives pulmonary venous connections, whereas the distal (lower or inferior) chamber contains LA appendage and true atrial septum containing fossa ovalis. ⋯ The majority of reported cases of cor triatriatum occur in infants with symptoms of pulmonary venous obstruction, with adult cases being rare. Herein, we describe an unusual case of cor triatriatum in a 17-year-old boy who presented for the first time with embolic cerebral infarction with left hemiparesis.

Malignant pulmonary edema in a pregnant woman caused by cor triatriatum.
Undiagnosed maternal congenital heart disease can result in significant risks to both mother and fetus. When maternal symptoms and signs are atypical of preeclampsia, broadening the differential diagnosis and multidisciplinary consultation can lead to improved outcomes. ⋯ A complete differential diagnosis for edema, hypertension, and dyspnea near term will allow for recognition of more rare conditions. Referral to cardiology in cases in which work-up is negative for preeclampsia may aid in earlier diagnosis and management. A team approach to management involving obstetrics and medicine will improve the rapidity with which rare conditions can be managed effectively.

Review Case Reports
Isolated cor triatriatum sinistrum and pregnancy: case report and review of the literature.
Isolated cor triatriatum sinistrum (CTS) is a heart malformation in which a perforated fibromuscular membrane divides the left atrium into two chambers. When communication between these chambers is restricted, a patient may have signs and symptoms of mitral stenosis. The later stages of pregnancy are associated with tachycardia and increases in intravascular volume. We describe how this altered physiology may affect pregnant women with asymptomatic CTS. We also review the literature relating to pregnancy in patients with CTS. ⋯ While our patient with isolated CTS and an unrestrictive intra-atrial membrane had an asymptomatic pregnancy and an uneventful labour, the literature review suggests that the increase in intravascular volume and heart rate that occurs during late pregnancy and after delivery may result in cardiac decompensation, even in patients with asymptomatic CTS.

Case ReportsExtracorporeal membrane oxygenation as a bridge to diagnosis in a 20-month old girl with pulmonary hypertension and right ventricular failure.
A 20-month old girl with severe pulmonary hypertension and cardiomegaly was admitted to the paediatric intensive care unit with right ventricular failure of unknown origin. Only after decompression of the heart chambers under extracorporeal membrane oxygenation (ECMO), did the pathognomonic membrane of Cor triatriatum become visible on echocardiography. ⋯ This case illustrates that ECMO can serve not only as a bridge to diagnosis, but can also facilitate correct diagnosis. Given the excellent outcome after surgical treatment, it is crucial that cardiologists rule out the possibility of cor triatriatum when assessing a child with unexplained pulmonary hypertension.
