Myocardial bridge of proximal LAD

[Riderfan3169]

Hello,
I am 34 y.o. Make hx if pacemaker due to a fib and heart block. Last week I went to hospital with severe chest pain. Had ct angio. Calcium score 0 and no cad. Thank god but I did have a vasospasm due to what was called a severe myocardial bridge of my proximal LAD. My cardiologist blew it off and said you have had it since birth only rarely will it be fatal.   Well rarely is enough for me. Anyone in canada know of someone willing to take this seriously? I asked if I have no cad why angina then and got well the bridge can cause that.  After researching I found bridges are not as "benign" as I was lead to believe. That my fib and my av blocks could actually be caused by this as well as increase in sudden cardiac death. I am very active but was told to " be active but don't exercise" not sure what that means, I just want this treated so I can live. I have 2 kids I would love to ensure I see them grow up without dropping on a bike ride. If anyone has any resource or info on a place that may take these seriously please message me
Thanks for your time
Chris

If the cause of your arrhythmias are due to the bridge, then they should perhaps consider surgery more seriously. Perhaps they could also do this through minimally invasive procedure because it doesn't involve grafting.

Well I have had issues my whole life Ed I have a pacemaker just to blocks and arrhythmias amd I have been cardioverted many times!!!! Guess I would just like a fix to stop the shocks and all thanks for your input though much appreciated

Well to put things into perspective, it is rare for these to be fatal and after 34 years without knowing the bridge was there, this is obviously being shown as correct. There are procedures to overcome this, but it depends on whether the cardiologist can weigh up your risk to be greater if nothing is done. What can be done? 1. In some cases where the muscle mass above the artery is small enough, stents can be inserted to hold the artery open. However, if you have no artery disease, I would highly recommend this option is avoided. You don't want anything put into your arteries which can cause endothelium damage and start disease. 2. Surgery to free the artery. This would involve cutting along the bridge, raising the artery, then tucking the muscle back under the artery. I can see this is a worrying time for you but just keep in mind that nothing has happened in 34 years. Are you waiting for the cardiologists to discuss your case and come up with a plan?
