Mell How is myocardial bridging treated?
Treatment of symptomatic patients with myocardial bridging consists primarily of pharmacologic therapy although percutaneous coronary intervention (PCI), myotomy, or coronary artery bypass grafting surgery (CABG) can be considered for selected patients refractory to maximal medical therapy.
What causes myocardial bridge?
Myocardial ischemia means that the heart muscle is not getting enough oxygen-rich blood. When the heart “squeezes” (contracts) during the heartbeat, the bridge of heart muscle can “tighten down” on the artery, pinching it and decreasing the blood flow.
Are myocardial bridges hereditary?
Dear Sondra: Myocardial bridging is present in 10 to 15% of autopsies. It is more frequent when the cardiac muscle is thick (like in hypertension). It is usually benign and as far as I know, not hereditary. Consult with your doctor about getting blood pressures under control – an important factor in everyone’s health.
How common is myocardial bridging?
The myocardial bridge is an anomaly characterized by a typical intramyocardial route of a segment of one of the major coronary arteries. This anomaly is more frequent than previously thought, and its reported incidence varies from 1.5% to 16% (1).
Is a myocardial bridge considered heart disease?
A myocardial bridge is a usually harmless condition in which one or more of the coronary arteries goes through the heart muscle instead of lying on its surface. Most bridges don’t seem to cause symptoms. However, some people with myocardial bridges can experience angina, or chest pain.
Can you Stent a myocardial bridge?
The patient remains free from angina and arrhythmias. To our knowledge, coronary stent implantation in myocardial bridging without angiographic evidence of arteriosclerotic lesions has been reported in only two patients who had acute myocardial infarction caused by the bridge.
Is a myocardial bridge a birth defect?
A myocardial bridge (MB) is a congenital heart defect in which one of the coronary arteries tunnels through the heart muscle itself (myocardium). In normal patients, the coronary arteries rest on top of the heart muscle and feed blood down into smaller vessels (ex.
Can myocardial bridging cause arrhythmia?
A myocardial bridge (MB) has been associated with ventricular arrhythmia and sudden death during exercise. QT dispersion (QTd) is a measure of abnormal repolarization and may predict ventricular arrhythmia.
Is myocardial bridge a heart disease?
A myocardial bridge is a usually harmless condition in which one or more of the coronary arteries goes through the heart muscle instead of lying on its surface. Most bridges don’t seem to cause symptoms.
Is myocardial bridge a heart defect?
What are the symptoms of myocardial bridge?
A myocardial bridge is a usually harmless condition in which one or more of the coronary arteries goes through the heart muscle instead of lying on its surface. Most bridges don’t seem to cause symptoms. However, some people with myocardial bridges can experience angina, or chest pain.
What is the treatment for myocardial bridge?
In most patients, a myocardial bridge is not treated if it is not causing any symptoms. In patients with symptoms, medicines such as beta-blockers and calcium channel blockers are usually the first line of treatment. In rare cases, patients need surgery to relieve their symptoms.
What is a cardiac bridge?
The bridge refers to the band of heart muscle (myocardium) that stretches over that section of the artery. A myocardial bridge shows up in fewer than 5% of people who undergo a cardiac catheterization, in which a doctor snakes a thin, flexible tube into a large blood vessel leading to the heart.
What is myocardial bridge surgery?
Unroofing the myocardial bridge entails cutting through the heart muscle to uncover the tunneled artery, thus relieving compression on the artery caused by the bridging. The surgery is known to be effective, Boyd said .
