Nonatherosclerotic Coronary Angina: Lung Steals Blood From the Heart (original) (raw)

Atypical Presentation of Coronary Artery Fistula: Case Report and Review of the Literature

Cureus, 2020

Chest pain is one of the common complaints a patient presents to the healthcare provider. It needs prompt evaluation to determine the cause and origin. Angina occurs when myocardial oxygen demand exceeds oxygen supply; the clinical manifestation is often chest discomfort. Atherosclerotic disease is the major cause of angina. However, several non-atherosclerotic conditions have been studied and reported in the literature that causes angina in rarity. We describe a case of coronary artery fistula (CAF) likely causing angina.

Acquired left coronary artery fistula draining to the cardiac vein system after acute myocardial infarction revealed by CT scan

Clinical imaging

Coronary artery fistula (CAF) is a congenital condition characterized by a pathological communication between a coronary artery and a systemic vein or one of the cardiac chambers. Iatrogenic CAFs were reported to develop secondary to the rupture of coronary aneurysm. Instances of acquired CAF draining into the cardiac chambers have been described after acute myocardial infarction. Angiography is the gold standard in diagnosing CAF. We describe the case of a patient who developed a fistula draining into the middle cardiac vein on the posterior interventricular sulcus, after acute myocardial infarction, revealed by CT scan.

Rare case of coronary to pulmonary vein fistula with coronary steal phenomenon

World journal of cardiology, 2014

Coronary artery fistulas are abnormal connections between coronary artery territories and cardiac chambers or major vessels, most of them are congenital. Patients with coronary artery fistula can be asymptomatic or present with different symptoms like angina. Cardiac computed tomography (CT) is one of the best modalities for diagnosis. We present an elderly patient that presented with angina symptoms, non invasive stress test was positive for ischemic heart disease, coronary angiogram could not reveal any obstructive lesions, but an abnormal branch of the left descending coronary artery (LAD), cardiac CT showed fistula that connect left anterior descending coronary artery to left superior pulmonary vein. Our case is extremely rare as most of the reported cases were fistulas between LAD and pulmonary artery, but in our case the fistula between LAD and left superior pulmonary vein. In addition, our patients' symptoms resolved with anti-ischemic medical treatment without any surgic...

Coronary Artery Fistula: Single-Center Experience Spanning 17 Years

Journal of Interventional Cardiology, 2007

Coronary artery fistula (CAF) is an uncommon form of congenital heart disease. It is often diagnosed incidentally during angiograms. We have reported on clinical characteristics, diagnosis, and management of CAF. Retrospective review of a tertiary referral institution's database identified 30 patients with CAF between 1987 and 2004. Mean follow-up was 31.61 +/- 48.03 months. Mean age was 60 +/- 12.7 years. Most common site of CAF origin was the left anterior descending artery (LAD) (14, 46.7%). The most common site of drainage was the main pulmonary artery (15, 50%). Therapeutic strategies were based on symptoms and shunt size. Conservative management was the option in 17 patients (56.7%) with small shunts and mild or no symptoms. Patients with moderate/severe symptoms and/or large shunts were treated with either percutaneous embolization (6, 20%) or surgical ligation (7, 23.3%). Four patients (13.3%) died during follow-up. No deaths were reported in the embolization group, two patients died of cancer in the conservative management group, and two patients died in the surgical group due to cardiac tamponade and cancer, respectively. Origin of CAF was predominantly from the left system. Clinical presentations were variable depending on type, size of fistula, and the presence of other cardiac conditions. Management of CAF is still controversial and treatment of adult asymptomatic patients with nonsignificant shunting is still a matter of debate. Newer imaging modalities may enhance noninvasive diagnosis. A national registry is necessary for further insights into optimal treatment for large fistulae and the natural history of smaller fistulae.

Coronary-pulmonary fistula: long-term follow-up in operated and non-operated patients

International Journal of Cardiology, 1990

Eleven cases with 13, incidentally found coronary-pulmonary fistulous communications were discovered out of about 11000 diagnostic coronary angiograms performed in different patients, over the period 1968 to 1989. These patients were followed-up for an average period of 4.4 years (range 2-11 years). The majority had a fistuious malformation originating from the proximal part of the left anterior descending artery and terminating in the pulmonary trunk. In three subjects, the right coronary artery participated in formation of the shunt. The fistulas consisted either of a convoluted mass of serpentive vessels, sometimes with aneurysmal formation, or of a solitary single vessel. Angina pectoris, atypical chest pain and fatigue were the most common symptoms. All patients were treated conservatively except one, who underwent ligation of the fistula and coronary arterial bypass grafting. Two subjects are still free of symptoms. No death occurred. None of the patients developed subacute bacterial endocarditis, acute myocardial infarction or left ventricular failure during the period of follow-up of more than four years. Three individuals, prior to the follow-up period, had suffered myocardial infarction contralateral to the shunt. They had no recurrence.

Coronary artery fistula: An unusual cause of chest pain in a young adult

Catheterization and Cardiovascular Interventions, 2011

Coronary artery fistula, usually congenital in origin, is an abnormal communication between a coronary artery and a cardiac chamber or great vessel [coronary sinus, pulmonary artery, pulmonary vein, or super vena cava (SVC)]. A coronary fistula can produce high-output heart failure from volume overload and/or myocardial ischemia from coronary steal phenomenon. A 35-year-old man was found to have a large fistula from the left circumflex coronary artery to the SVC-right atrium junction, an extremely rare anomaly. This patient developed right ventricular dysfunction and chest pain due to myocardial ischemia in the left circumflex coronary artery distribution for several months before evaluation. Because of the large size of the fistula, surgical ligation was chosen instead of coil embolization to close the fistula. The patient was free of chest pain postprocedure. Coronary artery fistulas, though rare, should be considered in the differential diagnosis when a young patient presents with chest pain and/or heart failure. V

Coronary-to-bronchial artery fistula in a patient with angina

Journal of Cardiology Cases, 2013

Coronary-to-bronchial artery fistulae are the most common found in adulthood and have often been associated with bronchiectasis and other abnormalities of pulmonary parenchyma. In this study we describe an unusual case in which circumflex coronary artery-to-left bronchial artery fistula was associated with the presence of extensive aneurysmatic dilatation of thoracic arteries. <Learning objective: This report deals with the case of a coronary-to-bronchial artery fistula (CAF) as the cause of atypical angina in a patient with normal coronary arteries. The concomitant finding of aneurysmatic dilatation of thoracic arteries controindicated an invasive approach. Medical therapy with vasodilators and anti-anginal drugs was soon started proving to be efficacious in symptoms relief.>
