Unroofed Coronary Sinus Atrial Septal Defect Misdiagnosed as Ostium Primum Defect

چکیده
https://e-kcj.org A 42-year-old woman presented with a 2-year history of shortness of breath. She was evaluated via transthoracic echocardiography at another institution and diagnosed with ostium primum atrial septal defect and advised to undergo surgery. Transthoracic echocardiography revealed a mildly enlarged right ventricle and mild tricuspid regurgitation with an estimated systolic pulmonary artery pressure of 40 mmHg. However, unroofed coronary sinus (UCS) was suspected when detailed reexamination was performed. Twoand three-dimensional (3D) transesophageal echocardiography (TEE) confirmed the diagnosis. The defect was repaired surgically. Enhanced temporal and spatial resolution 3D imaging enabled us to delineate the complex anatomy of an UCS without additional imaging modalities.

Nomenclature and Classification There are 3 major types of ASDs or interatrial communications: ostium secundum, ostium primum, and sinus venosus (Figure 1A) defects. The ostium secundum is a true defect of the atrial septum and involves the region of the fossa ovalis. The ostium primum defect is within the spectrum of the atrioventricular (AV) septal defects (Figure 1B; also known as AV canal d...

Defects in the atrial septum cause left to right shunt because the left atrial pressure is higher than that in the right atrium. This causes volume overloading of the right ventricle. While this is generally well tolerated in infancy and childhood, development of exercise intolerance and arrhythmias in later childhood and adolescence, and the risk for development of pulmonary vascular obstructi...

ATRIAL SEPTAL DEFECTS (ASD) ACCOUNT FOR 5% TO 10% OF ALL CASES OF CONGENITAL heart disease and as many as 30% of cases of congenital heart disease presenting in adulthood. These defects make up a spectrum of interesting and distinct entities. The ostium secundum ASD accounts for 70% to 80% of all adult ASDs. Other less common forms of adult ASDs include ostium primum ASD (15% of ASDs), sinus ve...
