[Clinical and angiographic characteristics of left coronaroventricular microfistula].
OBJECTIVE
To investigate the clinical and angiographic characteristics of left coronaroventricular microfistula.


METHODS
In his retrospective review, clinical, electrocardiogram, echocardiography and coronary angiography data were analyzed for patients with left coronaroventricular microfistula.


RESULTS
Left coronaroventricular microfistula was identified in 9 out of 8300 patients underwent coronary angiographies from 1998 to 2008 in our center. Seven patients were female (77.8%) and the average age was 71.5 years. All 9 patients had presenting symptoms of chest distress or dyspnea, coronary artery disease was documented in 5 (55.6%), hypertension in 2 (22.2%), valve disease in 1 (11.1%)and cardiomyopathy in 1 (11.1%) patient. Microfistula originated from one single coronary artery was seen in 1 patient (11.1%), from two coronary arteries in 6 patients (66.7%), from three coronary arteries in 2 patients (22.2%). The diagonal artery was involved in all patients. The characteristic sign of microfistula from CAG was intracavitary staining.


CONCLUSIONS
Microfistula between coronary arteries and left ventricle is a rare disease, often originates from two coronary vessels and diagonal artery is involved in most cases.
