Successful Surgical Closure of a Coronary Sinus Atrial Septal Defect Using a Heart-Shaped Patch.

Abstract

A 21-year-old man with coronary sinus atrial septal defect (ASD) was treated successfully. This case had been diagnosed as an ASD without a lower margin preoperatively but we confirmed this to be a coronary sinus ASD intraoperatively, and this case was classified as partially unroofed coronary sinus without PLSVC.The diagnosis of coronary sinus ASD before operation is sometimes difficult. Therefore we should pay attention to the location of the defect and the dilated coronary sinus in echocardiography, and the course of the cardiac catheter entering into the left atrium, for a correct diagnosis. In this case, the defect was located in the vicinity of the ostium of a large coronary sinus, therefore we could close the defect between the CS and the LA using a heart-shaped patch without any damage to the AV node.

A Surgical Case of Partially Unroofed Coronary Sinus Atrial Septal Defect in an Elderly Patient Diagnosed by Preoperative Contrast-Enhanced Computed Tomography

“…1) It is often difficult to have a distinct preoperative diagnosis of unroofed CSASD, and is often confirmed intraoperatively. [2][3][4][5] The complete surgical repair inevitably requires the precise detection of anatomical characteristics of unroofed CSASD, because detailed surgical decision making is mandatory for such a complex operative procedure to be safely performed. Therefore, it is considered essential to establish the diagnostic methodology to delineate the precise anatomical features of unroofed CSASD.…”

“…It is often difficult to make an accurate diagnosis of unroofed CSASD with conventional echocardiography. [2][3][4][5] However, preoperative precise detection of unroofed CSASD is considered essential for the surgical repair to be safely performed. Herein, we report a case with unroofed CSASD in which preoperative contrast-enhanced CT was useful to determine the operative procedure.…”
