Symptoma

Coronary Arteriovenous Fistula

We present a case of syncope in a young woman with a CAVF and no anatomic substrate for coronary steal. [ncbi.nlm.nih.gov]

  • Congestive Heart Failure

    Patients may present with congestive heart failure, ischemic chest pain, or endocarditis. [ncbi.nlm.nih.gov]

    Patients with such fistulas often have loud continuous cardiac murmurs and may have congestive heart failure, myocardial ischemia (due to a coronary-artery ”steal” phenomenon), and pulmonary hypertension. [nejm.org]

  • Loss of Appetite

    Nelson a, Adil Rajwani a a Cardiac Magnetic Resonance Imaging Department, Royal Adelaide Hospital, Adelaide, Australia Article A nonagenarian man with previously excellent functional status presented with progressive dyspnoea and loss of appetite. [revespcardiol.org]

  • Heart Disease

    This center, one of the most respected in Europe, has experience of a wide range of congenital heart diseases both in their diagnosis and management. [books.google.de]

    Furthermore, it may be useful for the detection of shunt cases, such as congenital heart disease. [ncbi.nlm.nih.gov]

  • Continuous Murmur

    The clinical symptoms and signs were feeding problem, continuous murmur, tachycardia, tachypnea, cardiomegaly, and exertional chest pain. Myocardial enzyme was elevated in 1 patient. [ncbi.nlm.nih.gov]

    Abstract In local experience coronary arteriovenous fistula or aortic sinus of Valsalva aneurysm rupture into the right heart are the two common causes of continuous murmurs with systolic accentuation which are maximum over the lower sternum. [annals.org]

    A loud continuous murmur heard at the lower or midsternal border of the heart suggests a coronary arteriovenous fistula; the diagnosis may be confirmed by coronary arteriography or aortography. [medical-dictionary.thefreedictionary.com]

    CAVF should otherwise produce a continuous murmur. Reference Sunil Roy TN, Sajeev CG, Francis J, Krishnan MN, Venugopal K. Three major coronary artery-to-left ventricular fistula: an unusual cause of a diastolic murmur at the apex. [cardiophile.org]

  • Exertional Chest Pain

    The clinical symptoms and signs were feeding problem, continuous murmur, tachycardia, tachypnea, cardiomegaly, and exertional chest pain. Myocardial enzyme was elevated in 1 patient. [ncbi.nlm.nih.gov]

    관상 동맥 중재술 중 Wire 손상에 합병되어 발생한 관상동맥루 1예 Abstract We report the case of a 51-year-old man who presented with worsening exertional chest pain in whom subsequent percutaneous coronary intervention resulted in a coronary arteriovenous fistula. [ekjm.org]

    The patient was suffering from retrosternal exertional chest pain for six months which relieved with rest. Previous medical history revealed hypertension and diabetes mellitus. [openaccessjournals.com]

  • Left Ventricular Dysfunction

    We repot a unique case with a fistulae originating from right coronary artery and draining into the right atrium via coronary sinus although Takotsubo-like left ventricular dysfunction or acute myocardial infarction was initially thought to have occurred [ncbi.nlm.nih.gov]

  • Suggestibility

    Noninvasive evaluation, including transesophageal echocardiography and magnetic resonance imaging, suggested the diagnosis. Angiographic diagnosis of concomitant atherosclerotic coronary disease may be difficult, and can require postoperative study. [ncbi.nlm.nih.gov]

    Cardiac catheterization is not diagnostic, although when correlated with the clinical picture it may strongly suggest the diagnosis. Angiocardiography, particularly retrograde aortography, is diagnostic. [pediatrics.aappublications.org]

    A loud continuous murmur heard at the lower or midsternal border of the heart suggests a coronary arteriovenous fistula; the diagnosis may be confirmed by coronary arteriography or aortography. [medical-dictionary.thefreedictionary.com]

  • Short Neck

    In our case, selective coronary arteriography showed that the CAVF from the left anterior descending coronary artery (LAD) was very close to the native coronary artery and had a very broad and short neck. [ncbi.nlm.nih.gov]

  • Incontinence

    A very violent attack can result in fistula- a tear in the walls separating the vagina and the bladder or the rectum, causing incontinence and strong odours, often leading to the victim being excluded from her community. [hujiang.com]

  • Sinus Arrest

    Sick sinus syndrome type III was diagnosed by paroxysmal atrial fibrillation (longest sinus arrest 9.0 sec) on 24-h Holter ECG recording. [ncbi.nlm.nih.gov]

Diagnosis and treatment implications are discussed. [ncbi.nlm.nih.gov]

With obliteration of the fistula by suturing, the prognosis is usually excellent. Figure 1 Coronary Arteriovenous Fistula on Coronary Angiography. [nejm.org]

Patients who have undergone a closure procedure tend to have an excellent prognosis 4. [radiopaedia.org]

Once patients become symptomatic, coronary AV fistulae result in a poor prognosis [ 7 ]. Early closure is recommended for symptomatic patients at all ages [ 8, 9 ]. [clinmedjournals.org]

Prognosis: Recent results of both transcatheter and surgical approaches indicate a good prognosis. Approximately 4% of patients may require additional surgery for recurrence. Life expectancy is considered normal. [rjmatthewsmd.com]

Etiology CAVFs are most commonly congenital, but can also be rarely acquired 3,4. [radiopaedia.org]

In this case, given the absence of localising findings, potential etiologies include isolated congenital fistulae or atherosclerotic aneurysm. [revespcardiol.org]

The coronary artery fistula’s etiology is not very well known, but most of the fistulas have a congenital origin. [romanianjournalcardiology.ro]

The objective of this study was to describe aspects of the natural history and pathophysiology of CAVF and to propose potential treatment strategies. [cardiothoracicsurgery.biomedcentral.com]

This contrasts with coronary arteriovenous fistulae in the absence of outflow obstruction, in which coronary steal is the primary pathophysiologic problem. [emedicine.medscape.com]

Transthoracic echocardiography could be used to diagnose CAVF, but poor acoustic penetration and low preoperative suspicion may prevent the identification of this uncommon coronary artery anomaly ( 2 ). [journals.lww.com]

Free wire tip motions are important to avoid catching the tip on plaque and to prevent vessel trauma, such as dissection ofperforation of the vessel. After acrossing the lesion, it is important to monitor the distal position of the wire tip. [ekjm.org]
