Myocardial bridge

What IS and the SIGNIFIGANCE of a LAD myocardial bridge ??

[mcgkcc1234]

Interesting I do tend to get angina symptoms more frequently when my HR exceeds 80bpm..I guess why I was placed on a beta blocker in addition to nitrates and CCBs as well. Also diagnosed with vasospastic angina and mild CAD..all affecting LAD. Severe LAD vasospasm caught on cath with acetylcholine , reversed with intracoronary Nitro.
My cardios tell me to exercise ..yet won't clear me for the gym..I am frustrated.

A bridge may not affect blood flow as the blood flows when the heart is at rest.  Usually a myocardial bridge is harmless. Patients with a myocardial bridge will have had it since birth, and most patients live their whole lives without ever knowing they have the condition.

Texas Heart Institute: For some insight and another perspective, "most of the blood flow through the heart happens during the "rest" phase of the heartbeat, not during the pumping phase. Even so, the tightening of the bridge on the artery can decrease blood flow enough that myocardial ischemia develops, especially during exercise or when the heart is beating quickly".

Some myocardial bridges cover longer sections of arteries, others are thinner and compress the vessel much less, so the ranges of bridges are huge. If the compression of the artery is not enough to give you symptoms, then nothing needs to be done. There are surgical options, such as removal of the bridge to free up the artery or putting a stent in the artery to hold it open, if the bridge is not so thick it will crush it.

As far as I understand it, a myocardial bridge is a malformation that makes that a part of the myocardial muscle cover a part of a coronary artery.

As a consequence, every time that the heart pulsate, it compress the artery stopping the flow of blood.

As per the significance of it, I suppose it will depend of the symptoms that you have.
