Coronary artery fistulas (CAFs) are infrequent congenital malformations, although some may be acquired: iatrogenic (during thoracic surgery or PCI) or traumatic. The incidence of CAFs has not been well defined but it is found in less than 0.2% of angiographic examinations. CAFs, even if rarely, may cause heart failure, spontaneous intrapericardial rupture or myocardial ischemia due to coronary "steal phenomenon". The literature reports very few cases of patients where a CAF was associated with a coronary artery disease (CAD). The consequences of this association on coronary haemodynamics and myocardial blood flow (BF) was poorly investigated.

Abstract
Coronary artery fistulas (CAFs) are infrequent congenital malformations, although some may be acquired: iatrogenic (during thoracic surgery or PCI) or traumatic. The incidence of CAFs has not been well defined but it is found in less than 0.2% of angiographic examinations. CAFs, even if rarely, may cause heart failure, spontaneous intrapericardial rupture or myocardial ischemia due to coronary "steal phenomenon". The literature reports very few cases of patients where a CAF was associated with a coronary artery disease (CAD). The consequences of this association on coronary haemodynamics and myocardial blood flow (BF) was poorly investigated.File | Dimensione | Formato | |
