The authors encountered a 4-month-old, female Shiba dog weighing 4.0 kg, who had been exhibiting abdominal distension and increasing ascites for 2 months. She was brought for further examination and treatment with the chief complaints of ascites and dyspnoea during sleep. The dog was diagnosed with ascites caused by cor triatriatum dexter based on the physical and imaging findings. Under general anaesthesia, she was treated with hybrid balloon dilation under transoesophageal echocardiography guidance. Her postoperative recovery was quite rapid and uneventful. This method appears to be a useful, new, and less-invasive treatment option for cor triatriatum dexter.

Cor triatriatum is a rare congenital malformation of the heart characterized by a fibromuscular membrane dividing the atrium into two distinct chambers. In the majority of cases, it is diagnosed in early childhood, whereas adult cases are extremely rare [1,2]. The hemodynamics of cor triatriatum are similar to those of mitral stenosis, which sometimes cause embolic infarction. We describe an unusual case of cor triatriatum sinistrum in a 48-year-old man who presented with relapsed embolic infarction.

We herein present a case of a successful correction of cor triatriatum associated with thrombotic pulmonary hypertension diagnosed in an adult female patient. We confirmed diagnosis using transthoracic and transesophageal echocardiography in addition to cardiac computed tomography and magnetic resonance imaging. Surgical repair comprised excision of the fibromuscular membranous septum in the left atrium, patch closure of an atrial septal defect, and reconstruction of the pulmonary arteries with a vascular graft. Cor triatriatum complicated pulmonary thrombotic hypertension with atrial septal defect is amenable to surgical correction with satisfactory results.

A 45-year-old woman with cor triatriatum sinister was admitted for laparoscopic resection of an ovarian tumor. Her medical history was benign with the exception of a single episode of syncope one year ago. A 1.5-cm membrane fenestration was found on echocardiography, but there were no other cardiac structural anomalies. General anesthesia was established with etomidate, sevoflurane, and remifentanil; no notable events occurred during the anesthesia. As cor triatriatum shows a clinical picture of mitral stenosis (MS), careful anesthetic management is required.

OBJECTIVE: To review the clinical data of pathological morphology, diagnosis, surgical treatment of cor triatriatum in 15 patients. METHODS: Fifteen patients with a mean age of (14.6+/-10.3) years (range from 6 months to 40 years) were performed operations under extracorporeal circulation. Fourteen of the patients had cor triatriatum sinister, and 1 had cor triatriatum dexter; 12 of the 15 patients had other cardiac abnormalities. The excision of the fibromuscular membrane was accomplished through a right atrial incision in all of the 14 cases, and the associated abnormalities were corrected at the same time. RESULTS: One patient died after the operation, and the other survivors had good outcome. CONCLUSION Operation is necessary if the diagnosis is clear. The patients generally have good prognosis. Surgical results of cor triatriatum depend on the complexity of associated defects and the adequacy of the repair.

The LEOPARD syndrome is an acronym and serves as a mnemonic for the features of this autosomal dominant syndrome : L - lentigines (multiple), E - electrocardiographic conduction abnormalities, O - ocular hypertelorism, P - pulmonary stenosis, A - abnormalities of genitalia, R - retardation of growth, and D - deafness (sensoryneural). The main features of the syndrome are multiple lentigines in combination with congenital heart malformations. These frequently accompanied cardiac abnormalities are pulmonary stenosis, hypertrophic cardiomyopathy, and various ECG abnormalities. It is advisable to make cardiac evaluation in a patient with LEOPARD syndrome in spite of no clinical symptoms or signs, since cardiac dysfunction may be progressive or developed later. We experienced a case of this syndrome in a 31 year-old female, presenting multiple lentigines, ocular hypertelorism, and congenital cardiac abnormalities of incomplete right bundle branch block and cor triatriatum. We report the case with brief literature review.

We report an unusual case of asymptomatic cor triatriatum found in a 30-year-old female suffering form Bechect's syndrome. Cor triatriatum was suspected from a routine echocardiography. The left atrium was divided into a posterior superior chamber and an anterior inferior chamber (true left atrium) by an echo-dense membrane. Two turbulent jet flows were demonstrated on transesophageal echocardiography. Catheterization and angiography demonstrated a mild increase in the pulmonary artery, and capillary wedge, pressures no associated anomalies, and with four pulmonary veins draining into the posterior chamber. The membrane was successfully resected by surgery.

We report one case of an 18-day-old female patient, weighing 3.4 kg, with severe cyanosis. The diagnosis was made with only transthoracic echocardiography, which revealed cor triatriatum with an atretic small opening of fibromuscular membrane, obstructive infracardiac total anomalous pulmonary venous drainage(TAPVD), severely restrictive interatrial communication, and scanty mitral inflow and aortic forward flow. The preoperative decision-making for biventricular repair was not easy due to collapsed left heart system caused by remarkably reduced blood flow. An emergent operation was performed due to severe cyanosis. All left heart structures were somewhat hypoplastic but thought to be adequate for systemic circulation. Biventricular repair was done without specific intraoperative problems. The postoperative course was uneventful. The patient has been doing well with no evidence of pulmonary vein stenosis or mitral regurgitation for 4 months after operation.
