Larger fistulas can cause coronary artery steal resulting in ischemia of segment of myocardium perfused by coronary artery distal to fistula. Uechi Y, Higa K. More on this topic Candida sepsis with intramyocardial abscesses mimicking left ventricular noncompaction. Arterio-luminal subtype, as in our case can be successfully closed by surgery, whereas arteri-sinusoidal type is less amenable to surgery and use of beta-blocker is described in the literature.

Oxford University Press is a department of the University of Oxford. Angiographic and clinical manifestations of coronary fistulas in Chinese people: Small fistulas are usually silent and are discovered incidentally on angiography [ 2 ], while large fistulas are diagnosed secondary to the complications. Coronary cameral fistula is a rare entity and is characterized by an abnormal communication between coronary artery and a cardiac chamber.

Left anterior descending artery; LCA: Chronic obstructive pulmonary disease; Cx: In this case, the diagnosis was established by conventional coronary angiography, though the coronary anatomy may alternatively be delineated using computed tomography coronary angiography.


A contrast enhanced multislice spiral computer tomography MSCT with retrospective ECG gated reconstruction was performed to delineate the site of origin and termination of the fistula. Eur J Cardiothorac Surg. Coronary arteries were angiographically normal.

Coronary–cameral fistula

Fistula connecting the left main coronary artery with the right atrium in a marathon runner. Shunt characteristics The magnitude of the shunt of MMFs may be considerable.

The origin of the fistula from the LAD was not clearly seen from multiple views and it appeared to drain into the coronary sinus. Brussee H, Gasser R. Heper G, Kose S. Abstract This is camerwl case series and review of the literature adding 11 new cases. Said SA, van der Werf T. Sinus rhythm was demonstrated in 22, atrial flutter in 1 and supraventricular tachycardia in 2 of the patients.

It also ruled out any coronary atherosclerosis as reason for chest pain and ischemic symptoms on exercise treadmill test.

The mitral valve ring is visible hollow arrow. Percutaneous therapeutic embolization; RA: In view of the stable angina, absence of fisstula murmur, and no objective evidence of coronary artery steal, the patient was managed conservatively.

These arterio-venous or arterio-arterial connection, giving rise to left-right or left-left shunts, respectively. One patient refused further treatment.

Journal List Heart Views v. Our findings were similar and in accordance with the findings of others[ 1 ]. For adult patients with congenital coronary artery-ventricular multiple micro-fistulas, conservative medical management is the treatment of choice. Inferior myocardial infarction; LAD: Increased myocardial ischemia during nitrate therapy: Two-dimensional and color Doppler echocardiography may reveal the dilated coronary artery and on color mapping may reveal the site of drainage; however, it is difficult to delineate the detailed anatomy of the fistula.

Multimodality non-invasive imaging of a coronary cameral fistula. J Thorac Cardiovasc Surg. Mitral valve plasty; MVR: The magnitude of the shunt of MMFs may be considerable. Autopsy findings Autopsy of patients with congenital multilateral MMFs to both ventricles depicted insignificant atherosclerotic coronary artery disease, cardiac dilatation and hypertrophy, and dilated coronary arteries with histologically, numerous small vessels of various diameters across the myocardium with patchy subendocardial fibrosis[ 5152 ].

Clinical and angiographic analysis of congenital coronary artery fistulae in adulthood.

Unilateral fistulas were present in 15, bilateral fistulas in 8 and multilateral fistulas in 1 coronady the patients. Three-vessel left-ventricular microfistulization syndrome: During the preparation of the manuscript, the assistance of the librarian, Mrs.

These fistulas are rare clinical entities that either usually result from congenital abnormalities or are acquired from trauma or invasive cardiac procedures.
