Abstract:
Objective To conclude the diagnostic methodology of unroofed coronary sinus (UCS) by two-dimensional echocardiography(2DE). Methods By analyzing the echocardiographic results of 16 UCS patients who were diagnosed by 2DE and confirmed by operation, the diagnostic methodology of UCS by 2DE was summarized. Results Sixteen patients with UCS were involved in this study. Among them, 12 cases were diagnosed as complete UCS,others were partial UCS(PUCS). Twelve patients were complicated with persistence of left superior vena cava (LSVC) that was connected to left atrium (LA) through UCS. All of preoperative diagnosis conducted by 2DE were finally confirmed to be consistent with the results of operation. With the analysis of acquired echo images,key points of diagnosis were concluded as follow: 1) normal coronary sinus (CS) could not be detected in the routine 2DE views referring CS. PUCS showed partial absence of CS roof,while complete UCS displayed as total absence of CS. 2)Inter-atrial shunt would definitely be found in UCS and the opening to right atrium must be coronary sinus orifice. The shunt direction was depended on the combined cardiac malformations. 3) With the occurrence of UCS,LSVC would be in junction with LA through UCS. 4) The inter-atrial shunt resulted in cardiac morphologic and hemodynamic changes. Conclusions Better understanding of the anatomic, morphological and hemodynamic characteristics of UCS would greatly contribute to accurate diagnosis on UCS.
