Case ReportsAortic dissection with fistula to left atrium: diagnosis by transesophageal echocardiography with successful repair.
The aorta-atria fistula is an infrequent complication of aortic dissection, and it is rarely diagnosed before death. A 41-year-old man who 8 years previously had undergone prosthetic aortic valve replacement had an aortic dissection complicated by aorta-left atrial fistula. This patient had acute left heart failure associated with a systolic and diastolic murmur at the lower left sternal border suggesting an aortic prosthetic malfunction. ⋯ On the basis of the echocardiographic findings, the patient underwent successful emergency replacement of the dissecting ascending aorta with closure of the aorta-left atrial fistula. Transesophageal echocardiography is the procedure of choice for defining this abnormality. In this case a prompt surgical repair consisting of replacement of the affected segment of the aorta with the prosthesis and closure of the fistula provided optimum resolution of the clinical situation.
