Patent Ductus Arteriosus With Eisenmenger Syndrome: Difficult Diagnosis Made Easily With Saline Contrast Echocardiography

摘要

The diagnosis of patent ductus arteriosus (PDA) with Eisenmenger syndrome is difficult. We report a case of 35-year-old male who came to our outpatient department (OPD) for evaluation of repeated hemoptysis and dyspnea on exertion. He had already completed two courses of ATT. On examination, grade 3 ejection systolic murmur was audible over precordium. Transthoracic echocardiography (TTE) showed enlargement of right atrium (RA) and right ventricular (RV) with severe tricuspid regurgitation (TR). On agitated saline contrast injection, agitated saline was seen in pulmonary artery followed by filling of abdominal aorta without filling of ascending aorta, thus confirming the diagnosis of right to left shunt with PDA.
