“…They demonstrated that the fistula was insensitive for adenosine administration and therefore concluded that there was no evidence for bstealQ phenomenon. It was clearly shown by Bitar et al, that basic coronary velocity was elevated in the fistula-bearing vessel [25].…”

“…Published papers on Caucasian population regarding CAFs and PAP between 1955 and 2014 were included for evaluation: 1955-1961[70-75], 1964-1967[5,76-78], 1971-1976[2,79-82], 1981-1989[11,83-85], 1990-1991[3,6,10,86,87], 1992-1994[88-92], 1995-1997[4,9,31,93-95], 2000-2002[12,13,96-101], 2003-2004[102-106], 2005-2006[7,15,107-113], 2007-2009[14,114-124], 2010-2012[8,125-130], and 2013-2014[131-134].

“…However, some can be sizeable and lead to shunting of blood from the coronary circulation to low-pressure pulmonary vascular bed, resulting in pulmonary hypertension (PHT)[1]. CAFs may be associated with normal[2-4] pulmonary artery pressure (PAP) in unilateral[5-8] or bilateral[9,10] fistulas, or may sometimes be accompanied with elevated PAP[11-14]. Rarely, in octogenarians with bilateral CAFs, PAP may remain normal[15].…”

AIMTo compare the behavior of pulmonary hypertension (PHT) associated with coronary artery fistulas (CAFs) between the Asian and Caucasian subjects.METHODSCAFs may be complicated with PHT secondary to left-to-right shunt. Literature review limited to the English language. A total of 211 reviewed patients were collected. Of those, 111 were of Asian and 100 were of Caucasian ethnic origin. The mean age of the Asian and the Caucasian groups of patients were 48.9 (range 19-83) and 49.9 years (range 16-85), respectively. In both groups, right heart catheterization was the most commonly (95%) used method for determining pulmonary artery pressure.RESULTSFrom all of the reviewed subjects, PHT was found in 49 patients (23%), of which 15 were Asian and 34 were Caucasian. In 75% of PHT subjects, mild to moderate PHT was reported and 76% of the fistulas had a vascular mode of termination. Treatment was surgical in 61%, followed by percutaneous therapeutic embolization (27%) and finally conservative medical management in 12% of PHT subjects. PHT was associated with a slight female gender predominance. The majority demonstrated mild to moderate PHT. PHT was reported more frequent in the Caucasian compared with the Asian ethnicity group. The majority of fistulas in patients with PHT had a vascular mode of termination. The results of this review are intended to be indicative and require cautious interpretation.CONCLUSIONThe likelihood for a CAF patient to develop PHT is presented when possessing the following features, with a Caucasian female having a fistula with a vascular mode of termination.

“…To explain this phenomenon it has been postulated that coronary steal is responsible for inducing ischemia. This has been previously demonstrated using coronary flow velocities , stress thallium scintigraphy , and fractional flow reserve (FFR) . It has been speculated that the interaction of CAF and mild‐moderate coronary artery stenosis may result in premature development of angina pectoris and ischemia .…”

Coronary artery fistulae are rare anomalous connections arising from the coronary circulation. We report a case of anterior wall myocardial ischemia caused by the combination of sequential coronary-to-pulmonary artery fistula and moderate (50-60%) stenosis of the left anterior descending coronary artery. Ischemia was demonstrated by myocardial stress perfusion imaging as well as fractional flow reserve. Percutaneous coronary intervention of the lesion resulted in resolution of ischemia.
