Abstract

We report a rare case of a direct communication-forming fistula between the left main pulmonary artery and left atrial appendage detected on computed tomography and color Doppler echocardiography.

Figure

• 

  Fig. 1 A 23-year-old woman with a continuous cardiac murmur. A transthoracic color Doppler echocardiography was performed on the pulmonary trunk in systole (A) and diastole (B). Note the dilatation and regurgitant flow (red color flow, arrow) in the pulmonary trunk in diastole on the parasternal view Note.-PT = pulmonary trunk, LAA = left atrial appendage area

• 

  Fig. 2 A 23-year-old woman with a continuous cardiac murmur. Oblique maximum intensity projection (MIP) and axial images of computed tomography show an abnormal direct communication (arrow) from the inferior aspect of the LMPA, close to the bifurcation site of the pulmonary trunk, to the left atrial appendage (A-C). The maximum diameter of the communicating fistula vessel was 6 mm in size. Note.-Ao = ascending aorta, LMPA = left main pulmonary artery, LA = left atrium, LV = left ventricle, RV = right ventricle
