Adult patent ductus arteriosus : An unusual cause of heart failure in an octogenarian female.

Patent ductus arteriosus (PDA) is the third most common congenital abnormality in which the arterial duct, which normally closes spontaneously after birth within 24-48 h in full-term infants, remains permanently open. Breathlessness is very common in elderly patients and can be caused by several comorbidities, mostly cardiac and pulmonary diseases. PDA as a cause of heart failure in this patient population is very rare and diagnosis depends on high clinical awareness. Here we present a case diagnosed with multimodality imaging including 3‑dimensional (3D) transthoracic and transesophageal echocardiography and 3D-volume rendering technique (VRT) computed tomography.
