Abstract Introduction Cor triatriatum dexter, or partitioning of the right atrium (RA) to form a triatrial heart, is an extremely rare congenital anomaly that is caused by the persistence of the right valve of the sinus venosus. The incidence of cor triatriatum is approximately 0.1% of congenital heart malformation. Typically, the right atrial partition is due to exaggerated fetal eustachian and the besian valves, which together form an incomplete septum across the lower part of the atrium. This septum may range from a reticulum to a substantial sheet of tissue Case report: 45-years old female patient with history of surgical closure of an atrial septal defect at the age of 14 years .She presented to our medical facility complaining of exertional dyspnea and bilateral lower limb edema for 4 years. On clinical examination, she had bilateral congested neck veins, a pansystolic murmur over the tricuspid area and a tender hepatomegaly. 2D Transthoracic Echocardiography revealed an unusual membranous structure that stretched across the right atrium with attachments superiorly at the free wall and inferiorly at the inter-atrial septum with a severe tricuspid regurgitation (Panel A)Intravenous agitated saline injection revealed an incomplete membrane. (Panel B).2D Transesophageal echocardiography showed an unusually prominent eustachian valve arose normally from the ostium of the inferior vena cava (IVC) and was pointing towards the interatrial septum just below the level of the fossa ovalis and no residual ASD could be seen. (Panel C) . 3D transesophageal echocardiography with zoomed mode from right atrial perspective confirmed the presence of an incomplete membrane extending transversely from the ostium of IVC and interatrial septum immediately below the fossa ovalis but not reaching RA free wall (arrow), no obstruction to the flow of the IVC, superior vena cava (SVC) , coronary sinus (CS) and the tricuspid valve (TV) was seen .(Panels D,E,F). Conclusion Since many patients are asymptomatic, the diagnosis of cor triatriatum dexter often is determined at postmortem examination. Antemortem diagnosis can be determined by echocardiography. 3D transesophageal echocardiography was able to detect cor triatriatum dexter that can be easily missed by 2D echocardiography.

SummaryWe describe the symptoms, the techniques for imaging and the surgical therapy in a patient with divided right atrium (‘cor triatriatum dexter’) combined with atresia of the superior caval vein. In addition to peripheral venous congestion and cyanosis, macrocephaly was the most prominent sign, the high pressure in the superior caval vein disturbing the circulation of cerebrospinal fluid. Transesophageal echocardiography was the optimal technique for imaging the dividing shelf in the right atrium. Cardiac catheterization after surgical excision of the shelf and reconstruction of the junction between the superior caval vein and the right atrium excluded any residual gradient or shunt.

Background: Although various synthetic materials and pericardium have been used for atrial septal defect (ASD) closure, investigators are continuing to search for an ideal material for this procedure. We report and evaluate a case in which autologous right atrial wall tissue was used for ASD closure. Case: In this case, we closed a secundum ASD of a 22-year-old woman who also had right atrial enlargement due to the defect. After establishing standard bicaval cannulation and total cardiopulmonary bypass, we opened the right atrium with an oblique incision in a superior position to a standard incision. After examining the secundum ASD, we created a flap on the inferior rim of the atrial wall. A stay suture was stitched between the tip of the flap and the superior rim of the defect, and suturing was continued in a clockwise direction thereafter. Considering the size and shape of the defect, we incised the inferior attachment of the flap, and suturing was completed. Remnants of the flap on the inferior rim were resected, and the right atrium was closed in a similar fashion. Results: During an echocardiographic examination, neither a residual shunt nor perigraft thrombosis was seen on the interatrial septum. The patient was discharged with complete recovery. Conclusion: Autologous right atrial patch is an ideal material for ASD closure, especially in patients having a large right atrium. A complete coaptation was achieved because of the muscular nature of the right atrial tissue and its thickness, which is a closer match to the atrial septum than other materials.

Hepatocellular carcinoma usually metastasizes to regional lymph nodes, lung, and bones but can rarely invade the inferior vena cava with intravascular extension to the right atrium. We present the case of a 75-year-old man who was admitted for generalized oedema and was found to have advanced HCC with invasion of the inferior vena cava and endovascular extension to the right atrium. In contrast to the great majority of hepatocellular carcinoma, which usually develops on the basis of liver cirrhosis due to identifiable risk factors, none of those factors were present in our patient.

Purpose. This study aimed to retrospectively review the diagnosis and surgical treatment of uterine intravenous leiomyomatosis (IVL). Methods. The clinical data of 14 patients with uterine IVL admitted to our hospital between 2013 and 2018 were retrospectively analyzed, including their demographics, imaging results, surgical procedures, perioperative complications, and follow-up results. Results. The tumors were confined to the pelvic cavity in 7 patients, 1 into the inferior vena cava, 4 into the right atrium, and 2 into the pulmonary artery (including 1 into the superior vena cava). Only one case was misdiagnosed as right atrial myxoma before the operation, which was found during the surgery and was treated by staging surgery; all the other patients underwent one-stage surgical resection. Three patients underwent complete resection of the right atrial tumor through the abdominal incision, and one patient died of heart failure in the process of resection of heart tumor without abdominal surgery. During the 6–60 months of follow-up, 4 patients developed deep venous thrombosis of the lower extremity, and 1 patient developed ovarian vein thrombosis and pulmonary embolism. After anticoagulation treatment, the symptoms disappeared. One patient refused hysterectomy and the uterine fibroids recurred 4 years after the operation. Conclusion. Specific surgical plans for uterine IVL can be formulated according to cardiac ultrasound and computed tomography (CT). For the first type of tumor involving the right atrium, the right atrium tumor can be completely removed through the abdominal incision alone to avoid thoracotomy. The disease is at high risk of thrombosis and perioperative routine anticoagulation is required.

AbstractWe report the case of a child with cor triatriatum dexter masquerading as Ebstein's anomaly on transthoracic echocardiography. This was attributed to a floppy membrane arising from the right atrium, protruding into the tricuspid valve and pushing the leaflets downwards, giving an impression of Ebstein's anomaly. The importance of recognising this pitfall will prevent misdiagnosis of Ebstein's anomaly.

Chiari network occurs due to incomplete resorption of right valve of sinus venosus. It is often noticed as fenestrated membranous structure or reticular network like structure in the valve of inferior vena cava and coronary sinus. The remnant of left venous valve is observed as trabeculae over the fossa ovalis. The incidence of Chiari network and the remnant of left venous valve were studied in 80 cadaveric hearts utilized for teaching the undergraduates. The right atrium was opened anterior to sulcus terminalis and the interior was examined for the presence of these embryological remnants. The incidence of Chiari network and left venous valve in the present study is 3.75% and 7.5%, respectively. Chiari network was observed as a fenestrated membranous structure in 2 specimens and a reticular network in 1 specimen, with variable extension to coronary sinus opening and right atrial wall. The remnant of left venous valve was observed as multiple fine strands in 3 specimens and trabecular structure in 3 specimens. These structures may create diagnostic confusion, difficulty in interventional procedures, and complications like thromboembolic events. Hence, the knowledge about the incidence, morphology, and clinical manifestations of these rare embryological remnants is mandatory.

A 37-year-old immunocompromised woman was admitted with palpitations, fevers and myalgias. An echocardiogram demonstrated a mass in the right atrial walls and interatrial septum. Endovascular biopsy of the myocardium revealed neutrophilic necrotising myocarditis isolated to the right atrium. Multiple blood, urine and stool cultures were negative but a high anti-streptolysin O antibody titre was detected. The combination of these findings led to the working diagnosis of necrotising myocarditis. Without a positive culture, it was not possible to definitively state the cause of this condition. She was treated with intravenous antibiotics and continued to improve physically and biochemically on discharge.

Background During tricuspid valve replacement in a patient with previous mitral valve surgery, we made an incidental observation that the right atrium can be opened without caval snaring and without air entering the venous reservoir. We tested this hypothesis on an animal model. Methods Two patients underwent right atrial surgery using percutaneous cannulation, and no air was entrained without caval snaring. This principle was tested in an animal model using 2 pigs weighing 80 kg each. Percutaneous cannulae were placed under epicardial echo guidance with their tips 4 cm from the right atrium. A “collapsible bag with air drainage system” was introduced into the venous return system to quantify air return from the superior vena cava (SVC) and inferior vena cava (IVC). Two types of percutaneous cannulae with (Cardiovations Quick Draw) and without (Biomedicus) proximal side holes were tested. Results In the animal model using Biomedicus cannulae, upon opening the right atrium, air was entrained from the SVC cannula at 60 mL/minute with no air in the IVC. There was no difference in the amount of air between the two cannulae. Pressures measured were 5 cm of water in the IVC and −20 cm water in the SVC. Epicardial ultrasound demonstrated complete collapse of both vena cavae. Partial clamping of the SVC cannula reduced the amount of air to 60 cc/min, and placing a small straight clamp at the SVC atrial junction eliminated the air. No air was noted in IVC cannula. Conclusions Inferior vena caval drainage by percutaneous cannula does not entrain air with either type of cannula and without snaring (both in clinical cases and animal model). This might be explained by the presence of a competent Eustachian valve. However, the SVC is not immune to air. Minimal air (approximately 60 mL/minute) could be managed by partial clamping or completely be avoided by placing a small straight clamp without snaring.

Background and Objectives: A rare case of cor triatriatum sinistrum in combination with anomalies in the atrial septum and in the right atrium of a 60-year-old female body donor is described here. Materials and Methods: In addition to classical dissection, ultrasound and magnetic resonance imaging, computer tomography and cinematic rendering were performed. In a reference series of 59 regularly formed hearts (33 men, 26 women), we looked for features in the left and right atrium or atrial septum. In addition, we measured the atrial and ventricular wall thickness in 15 regularly formed hearts (7 men, 8 women). Results: In the case described, the left atrium was partly divided into two chambers by an intra-atrial membrane penetrated by two small openings. The 2.5 cm-high membrane originated in the upper level of the oval fossa and left an opening of about 4 cm in diameter. Apparently, the membrane did not lead to a functionally significant flow obstruction due to the broad intra-atrial communication between the proximal and distal chamber of the left atrium. In concordance with this fact, left atrial wall thickness was not elevated in the cor triatriatum sinistrum when compared with 15 regularly formed hearts. In addition, two further anomalies were found: 1. the oval fossa was deepened and arched in the direction of the left atrium; 2. the right atrium showed a membrane-like structure at its posterior and lateral walls, which began at the lower edge of the oval fossa. It probably corresponds to a strongly developed eustachian valve (valve of the inferior vena cava). Conclusions: The case described suggests that malformations in the development of the atrial septum and in the regression of the valve of the right sinus vein are involved in the pathogenesis of cor triatriatum sinistrum.
