Calcified patent ductus arteriosus diagnosed following aortic valve replacement

Incidental Finding on MDCT of Patent Ductus Arteriosus: Use of CT and MRI to Assess Clinical Importance

“…Detailed anatomic and physiologic information is necessary to consider the appropriate clinical management. Both MDCT angiography and cardiac MRI can depict the precise anatomy of this abnormality [5][6][7]. The purpose of this study is to outline the imaging features of incidental PDAs on MDCT angiography and to emphasize the unique contribution of cardiac MRI in hemodynamic cardiac evaluation that is necessary for clinical interventional decisions.…”

“…MDCT enables precise visualization of the location, size, presence and extent of calcification, and the relationship to adjacent anatomic structures. Cardiac-gated MDCT has been previously shown to identify these defects in patients with known PDAs detected by echocardiography or catheter angiography [6,7]. The axial source images should first be assessed for the caliber of the main pulmonary artery (Fig.…”

Patent Ductus Arteriosus in Older Adults: Incidental Finding or Relevant Pathology?

“…PDA is a rare diagnosis in older adults that was first reported in a postmortem of a 66‐year‐old woman in 1897 . Symptoms and signs of heart failure, whether or not there is a murmur, require further investigation, but small PDAs can escape detection to the echocardiographer and the cardiac surgeon …”

A Silent Patent Ductus Arteriosus

“…Transesophageal echocardiography has provided for better visualization and flow interrogation of posterior cardiac tissues and has allowed for the detection of PDAs missed by magnetic resonance imaging (MRI) 11 and cardiac catheterization. 12 In these reports, the diagnosis was made incidentally during the TEE examination of patients undergoing cardiac surgery, and the finding proved essential to intraoperative management. One patient had undergone a prior Bentall procedure without a TEE, and the PDA was undetected until the second aortic surgery.…”
