Background Unroofed coronary sinus syndrome (UCSS) is rare and often associated with the left superior vena cava (LSVC). We report our experience of the clinical features, diagnosis, associated anomalies, surgical procedures, and late outcomes of UCSS during a 20‐year period. Methods One hundred and fifty‐nine patients with UCSS were treated surgically and followed up between May 1998 and May 2019. UCSS was confirmed by preoperative echocardiography or computerized tomography (CT) scan in 97 patients and by the surgeons intraoperatively in 62 cases, and 100 cases were associated with LSVC. Among these patients, eight cases underwent ligation, and the intracardiac tunnel or baffle was reconstructed in 71 cases to ensure drainage of the LSVC into the right atrium (RA), and the extracardiac procedure was to lead the LSVC into the RA in three patients. Coronary sinus opening was diverted to the RA by the atrial septal patch in three cases. Thirteen patients underwent the reroof procedures, and two patients had untreated LSVC. The associated cardiac lesions were corrected concomitantly. Results There were five in‐hospital deaths. Follow‐up of 143 patients of early survivors was done, and no deaths were reported. No serious complications were observed, with the exception of avulsion of the internal tunnel patch in one patient. Conclusion UCSS is often misdiagnosed during preoperative evaluation of congenital heart diseases. Preoperative transthoracic echocardiography remains the most important method in the diagnosis of UCSS. We adopted multiple surgical approaches to manage the different types of UCSS with LSVC with good results.
