A 15-year-old male patient presented with a 3-year history of recurrent dizziness and headaches and was initially diagnosed with patent foramen ovale. A transcatheter closure procedure was planned and conducted under general anesthesia, utilizing ultrasound guidance through the femoral vein. Preadmission echocardiography confirmed the presence of a patent foramen ovale. However, further investigation with transesophageal echocardiography (TEE) performed under general anesthesia, revealed that the observed atrial septal anomaly was not a patent foramen ovale. Instead, real-time TEE identified it as the left atrial opening of the coronary vein. Subsequent detailed TEE tracking confirmed a rare case of coronary sinus ostium atresia with left atrial reflux of the coronary vein, leading to a significant revision of the initial diagnosis and planned treatment., (© 2024 Wiley Periodicals LLC.)

A coronary sinus (CS) interatrial connection is a rare congenital anomaly which can be in various types from atrial septal defect type unroofing CS to the total absence of the CS. The pathology usually accompanies the left superior caval vein (LSCV) draining to CS and in case of its absence directly to the left atrium (LA). We present a 53-year-old woman after surgical correction of a secundum atrial septal defect in 1974, with a CS interatrial connection and paroxysmal atrial fibrillation (PAF). She gave a history of PAF and was admitted to our clinic due to progressive exertional intolerance, peripheral edema, and mild hypoxia (SatO 2 92%) with subsequent cyanosis. Transthoracic echocardiography showed a left-to-right shunt in the posteroinferior part of the atrial septum. Computed tomography revealed a persistent LSCV draining directly into the LA, the absence of the CS, and cardiac veins draining into the LA. The right atrium (RA) and the LA were connected via a tunnel with a visible contrast passage from the left to the right side-the persisting mouth of the coronary sinus. The patient was qualified for surgical correction. A glutaraldehyde-treated autologous pericardial patch was used to construct the tunnel connecting the LSVC and the RA. The second part of the patch was used to close the atrial communication at the inferior vena cava level. The patient had an uncomplicated postoperative course and is now classified in New York Heart Association Class II., (© 2020 Wiley Periodicals LLC.)

In the spectrum of congenital heart diseases, anomalies involving the venous coronary sinus have received relatively little attention, although they are often associated with major congenital defects, such as atrioventricular septal defects. In cases of mitral surgery in patients with these conditions, it is mandatory to keep the problem in mind and to respect the coronary sinus when approaching the left atrium and the mitral valve., (© 2019 Wiley Periodicals, Inc.)

We present a 32-year-old patient with cortriatriatum sinister with Raghib's complex (a left persistent superior vena cava draining into the left atrium with an absent coronary sinus and an atrial septal defect [ASD]) who underwent successful surgical correction with excision of the cortriatriatum, closure of the ASD, and establishing the drainage of the persistent left superior vena cava to the right atrium via interposition of an extracardiac 13-mm ringed polytetrafluoroethylene conduit., (© 2017 Wiley Periodicals, Inc.)

We report the management of an acquired Gerbode defect, from the left ventricle to the coronary sinus, following mechanical mitral valve replacement. Following a failed percutaneous closure, surgical patch closure of the defect was performed., (© 2017 Wiley Periodicals, Inc.)

Background: Repair of unroofed coronary sinus defect in the presence of left superior vena cava is challenging and requires prosthetic graft material to redirect flow to the right atrium. This may potentially cause a supra-mitral gradient or pulmonary venous obstruction., Methods: Three patients with unroofed coronary sinus in the presence of a left superior vena cava (LSVC) underwent modified cavo-atrial anastomosis (Warden technique) to achieve reimplantation of the LSVC in a retro-aortic fashion to the right atrial appendage., Results: Three patients recovered well with no evidence of an intracardiac shunt. Postoperative echocardiography demonstrated normal venous flows in the LSVC., Conclusion: This modified technique offers correction of this systemic venous anomaly without the need for any additional graft material., (© 2016 Wiley Periodicals, Inc.)

In a 76-year-old female undergoing coronary artery bypass surgery, a persistent left hepatic vein was observed. Draining of this vein into the coronary sinus is an extremely rare embryological malformation and this is the first case to be reported as a solitary malformation in absence of other cardiac malformations., (© 2015 Wiley Periodicals, Inc.)

A 30-month-old female was admitted with recurrent spells and severe cyanosis. Preoperative echocardiography was diagnostic of tetralogy of Fallot with an atrial septal defect of the primum type, unroofed coronary sinus, and a left superior vena cava draining into the left atrium. At surgery the patient was found to have a complete atrioventricular septal defect in addition to these anomalies. Complete anatomical correction was achieved through the right atrial approach., (© 2015 Wiley Periodicals, Inc.)

Total anomalous pulmonary venous connection can be encountered in patients with a univentricular heart and must be addressed to at the time of univentricular palliation. We present an alternative technique of re-channeling of the pulmonary venous return toward the left heart in these patients., (© 2013 Wiley Periodicals, Inc.)

Background: Partially unroofed coronary sinus (PUCS) is a rare congenital cardiac anomaly and prone to be misdiagnosed. The purpose of this study was to explore the value of transesophageal echocardiography (TEE) in CS imaging for the detection of PUCS and to develop a special two-dimensional TEE-based en face view of CS., Methods: Twenty adult patients with suspected PUCS, showing a dilated coronary sinus and an enlarged right heart on transthoracic echocardiography (TTE), underwent TEE examination. In the mid-esophageal plane and close to an angle of 120°, the en face view of the CS successfully imaged the roof of the CS, which was beyond the realm of the atrial septum, and the interatrial septum was obtained simultaneously in the same view. Meanwhile, the 3D zoom mode could clearly display the comprehensive volume image and the adjacent structures of the PUCS. The results of TEE were compared with the findings of surgery or catheterization., Results: En face view of the CS was obtained successfully by 2DTEE in 20 patients. In addition, 3DTEE was used for imaging of PUCS in 11 of the 20 patients. PUCS was ultimately confirmed in 13 patients either by surgery or catheterization. The TEE for PUCS diagnosis was consistent with the surgical findings., Conclusion: Transesophageal echocardiography can be successfully applied to obtain the comprehensive view of CS and its surrounding structures. The en face view of CS provided by 2DTEE may be helpful in better understanding PUCS and discriminating it from associated atrial septal defects., (© 2013 The Authors.

Unroofed coronary sinus (UCS) is a rare cardiac anomaly that results in communication between the coronary sinus and the left atrium. We described an unusual presentation of UCS in a 48-year-old female that was not corrected during an initial secundum ASD repair 22 years ago., (© 2012 Wiley Periodicals, Inc.)

We present a rare case of a patient with a dilated unroofed coronary sinus mimicking cor triatriatum that altered mitral inflow in a cardiac-type total anomalous pulmonary venous connection. The membranous tissue in the left atrium, thought to be cor triatriatum tissue preoperatively, was actually a remnant of a dilated coronary sinus tissue. Although this tissue did not create a significant pressure gradient and merely induced a turbulent mitral inflow, we resected it to avoid future problems with mitral leaflet function., (© 2012 Wiley Periodicals, Inc.)

Coronary sinus type of atrial septal defect (ASD CS) is a rare cardiac anomaly and is rarely diagnosed by only transthoracic echocardiography prior to surgical operation. We now describe a technique to treat this defect with the aid of two-dimensional echocardiography, which prevents trauma to the conduction system and maintains drainage from the coronary sinus into the right atrium (RA)., (© 2011 Wiley Periodicals, Inc.)

We, herein, report a patient with persistent left superior vena cava with enlarged coronary sinus and absent right superior vena cava. This anomaly, diagnosed intraoperatively during the third open-heart surgery in the course of transesophageal echocardiography examination, was not mentioned during the patient's previous two cardiac operations. Challenges in intraoperative management and implications for subsequent treatments are discussed.
