title: [Congenital coronary artery fistulae in adults: diagnosis and surgical treatment].
abstract: OBJECTIVE
  To summarize the clinical characteristics, diagnosis and surgical in-treatment results of congenital coronary artery fistulas (CAF) in adults.
  
  
  METHODS
  Fourteen patients (8 men, 6 women), aged from 18 to 60 years with a mean of 32 +/- 13 years, underwent surgical correction of CAF between March 1985 and April 2002. Eleven of the 14 patients (78.57%) were symptomatic. The diagnosis of CAF was made by echocardiography or angiocardiography preoperatively. The fistulae originated from the right, left and double coronary arteries in 10 (71%), 3 (21%) and 1 (7%) patient(s), respectively. The fistulae drained into the right ventricle (8 patients), left ventricle (4), right atrium (1) and pulmonary artery (1), respectively. The diameter of fistulae ranged from 0.30 to 1.80 cm with a mean of (1.16 +/- 0.49) cm. There were 6 CAF patients associated with coronary artery aneurysms and 4 CAF patients with other coexisting cardiac defects. The distal fistulae were closed in 10 patients with cardiopulmonary bypass (CPB) and 4 patients without CPB. The coexisting defects were corrected simultaneously.
  
  
  RESULTS
  There was no early and late death. One patient had low cardiac output syndrome and cured during early postoperative period. Twelve patients (85.71%) were followed up for a mean period of 3.35 +/- 4.28 years without myocardial ischemia or infarction and recurrent fistulae. Heart function was improved to NYHA functional class I in 11 patients and class II in 1 patient.
  
  
  CONCLUSIONS
  All adult patients with CAF who have demonstrable hemodynamic and cardiovascular morphological changes should be surgically treated as early as possible. The appropriate surgical management and reliable myocardial protection are key points of good surgical results.
