ABSTRACT
AIM:
To analyse the multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) findings in patients with atresia of the coronary sinus orifice (CSA). MATERIALS ANDMETHODS:
MDCT findings of 15 consecutive adult patients with CSAs were retrospectively analysed. The patients underwent contrast-enhanced electrocardiography-gated MDCT (n = 13) or both CT and MRI (n = 2).RESULTS:
The mean size of the coronary sinus (CS) was 14.2 mm (range 5.5-24 mm) and 11 patients (73.3%) showed CS dilatation (diameter ≥12 mm). The mean length of the atretic CS segment was 2.9 mm (range 0-8 mm). Different forms of venous collateral pathways were observed in the CSA patients. Nine (60%) of the 15 CSA patients had communication between the right atrium (RA; n = 6) or LA (n = 5) and CS via intraseptal veins; six patients (40%) had persistent left superior caval veins; communications were also observed between the CS and RA (n = 4) or LA (n = 4); two patients had collateral venous pathways between dilated cardiac veins with RA; two patients had unroofing of the CS as outlet channels. Nine patients (60%) had cardiac anomalies coronary artery fistula to the pulmonary artery (n = 6) or left ventricular base and CS (n = 1), atrial septal defects (n = 2), and a ventricular septal defect (n = 1).CONCLUSION:
CSA patients have venous collateral pathways and a high incidence of associated cardiovascular anomalies such as coronary artery fistulae and atrial septal defects.
