Dual Coronary-Pulmonary Artery Fistula in a Patient with Severe Bicuspid Aortic Valve Stenosis.
Methodist Debakey Cardiovasc J
April 2023
A 62-year-old male presented to the emergency department with acute viral bronchitis and worsening of his chronic dyspnea on exertion. Incidentally, a murmur was detected on physical examination. Extensive work-up, including coronary computed tomography angiography, revealed a rare combination and potential association between severe bicuspid aortic valve stenosis and coronary-pulmonary artery fistulas.

- Tissue Doppler imaging (TDI) patterns from the left atrial appendage (LAA) were assessed using transesophageal echocardiography, revealing characteristic triphasic or biphasic tissue velocities similar to LAA flow.
- TDI velocities showed a strong correlation with flow measurements and were effective in patients with atrial fibrillation.
- Patients who experienced an embolic cerebrovascular incident had higher TDI velocities from the LAA compared to those without events, suggesting that TDI may enhance assessment of LAA function for thromboembolism risk.
