Introduction: Sinus of Valsalva aneurysm (SOVA), a rare cardiac malformation, is usually congenital and rarely acquired and most commonly occurring in the right coronary sinus. The clinical presentation of patients with SOVA varies. It is usually asymptomatic when it has not ruptured, and when it compresses neighboring structures or ruptures, it can lead to heart failure or shock, at which point urgent surgical intervention is usually required. Rupture of the sinus of Valsalva aneurysm (RSOVA) during pregnancy is really hard to come by, especially if the clinical presentations resemble that of an acute myocardial infarction. This report describes a pregnant woman with severe chest pain and hypotension with aVR and V1 ST-segment elevation due to RSOVA., Patient Concerns: Effects of RSOVA on the fetus, disease survival, and prognosis., Diagnosis: RSOVA., Interventions: Open SOVA repair., Outcomes: The patient's blood pressure returned to normal range and clinical symptoms disappeared after the surgery. After 3 months of follow-up, the patient was hemodynamically stable without chest discomfort, and an echocardiogram showed a normal aortic sinus., Conclusion: Progressive aneurysm dilatation or rupture has a poor prognosis. A thorough history and physical examination are fundamental, with echocardiography being the initial diagnostic tool of choice, and other ancillary tests (e.g., computed tomography) being used to complement and confirm the diagnosis. Surgery remains the current treatment of choice for patients with RSOVA, while the continuation of pregnancy in pregnant patients with RSOVA remains a case-by-case measure., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Imaging of the coronary sinus and its tributaries has gained increasing significance consequent to the development of an array of electrophysiological and interventional procedures using the cardiac venous system, including ablation for arrhythmias, left ventricular pacing, and in the administration of retrograde cardioplegia. Knowledge of the normal anatomy and the possible anomalies and their clinical significance is imperative to circumvent possible complications. A number of coronary sinus (CS) anomalies, both symptomatic and asymptomatic, have been observed with the widespread use of noninvasive cross-sectional imaging for the imaging of the heart. However, it should be kept in mind that even clinically occult lesions of the CS can cause disastrous complications in specific interventions. Hence, a thorough knowledge of the expected anatomy and the possible anomalies involving the CS along with their clinical significance is imperative for the reporting radiologists and the concerned physicians. In this review, we briefly describe the relevant anatomy and embryology and describe the gamut of anomalies pertaining to the CS and its draining veins on multidetector computed tomography angiography along with their clinical importance.

An 8-year-old asymptomatic child was referred for surgical repair of coronary sinus atrial septal defect resulting in significant left-to-right shunt and right chamber volume overload. The septal fenestration was located near to its drainage site into the right atrium. Due to this seemingly favourable anatomy, transcatheter closure of the septal defect was performed using an Amplatzer Septal Occluder device. The echocardiographic postprocedural evaluation imaged the occluding device almost perpendicular to the atrial septum, seemingly floating above the mitral valve orifice, like an alien spaceship inside the heart.

A classification is presented of anomalies involving the coronary sinus. These anomalies are classified into four anatomic groups on the basis of (1) enlargement of the coronary sinus, (2) absence of the coronary sinus, (3) atresia of the right atrial coronary sinus ostium, and (4) hypoplasia of the coronary sinus. Anomalies involving the coronary sinus often are associated with other venous anomalies, either of the systemic or the pulmonary circulation. In some there is no basic disturbance of the circulation. Those conditions involving the coronary sinus which are of major functional significance participate in shunts, either left-to-right or right-to-left in nature. Enlargement of the coronary sinus in the absence of a shunt usually indicates that a systemic venous channel joins the coronary sinus anomalously.
