- W4311755286 abstract "Abstract A 72-year-old woman who had been diagnosed with pulmonary emphysema and permanent atrial fibrillation was admitted to our emergency department with signs and symptoms of heart failure (NYHA class III). Transthoracic echocardiography (TTE) revealed dilatation of both right and left atria, dilatation and systolic dysfunction of the right ventricle (RV) and severe pulmonary hypertension. Combined severe mitral and tricuspid regurgitation was also noted and, after clinical stabilization, transesophageal echocardiography (TEE) was performed to better assess valvular anatomy and function. TEE revealed clear evidence of a pre-tricuspid left-to-right shunt with signs of significant RV volume overload, but with difficulties in defining the characteristics of a suspected atrial septal defect (ASD). CMR confirmed the presence of a large coronary sinus ASD (Panel A) as responsible for a significant left-to-right shunt (Qp/Qs ∼ 3,5, measured by phase-contrast imaging after correcting for the combined mitral and tricuspid regurgitation; Panel B), as well as severe RV dilatation and dysfunction. Pulmonary venous drainage was normal. Persistent left superior vena cava (SVC; Panel C) draining directly into the left atrium (LA) and a completely unroofed coronary sinus were unveiled. The extremely rare combination of an unroofed coronary sinus with abnormal systemic venous drainage from double SVC circulation (usually as a persistent left SVC) is also known as Raghib syndrome (or Raghib complex). In the ASD with completely unroofed coronary sinus there is no common wall separating the coronary sinus from the LA, making the depiction of the shunt anatomy particularly difficult to assess with echocardiography. When unrecognized in the perinatal age, clinical natural course of Raghib syndrome can vary based on the severity of RV volume overload, and late (or very late) clinical presentations have been rarely reported. CMR, with its large field-of-view capability and multiparametric approach, provides accurate definition of cardiac and great vessels anatomy and function allowing the full non-invasive depiction of most congenital abnormalities. In many cases, multimodality imaging is the key to reach a full depiction of these complex conditions, particularly when adult patients with possible comorbidities need to be evaluated." @default.
