How serious is a circumflex artery blockage that is 90%? Would this likely be fatal and if so, how long before one would have that result on average?

How serious is a circumflex artery blockage that is 90%?  Would this likely be fatal and if so, how long before one would have that result on average?

Coronary artery : High grade circumflex disease coul be the cause of angina or infarction. It could be fatal but less likely than lad disease. If well treated you could live a long time with that disease and something else could get you. Smoke and don't work on your condition and chances in infarction are excellent. ...Read more

Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more

Have relatively short 100% blockage in mid LAD &100% posterolateral branch of circumflex artery (both relatively small targets).Will stent help or ris?

stent: There are technical factors in deciding whether stenting is possible and physiologic predictions of whether successful stenting will yield benefit. Your doctors including interventional cardiologist are best to advise you regarding your specific situation. ...Read more

Can you do angioplasty stent on restively short 100% blockage in mid LAD and 100 % posterolateral branch of circumflex artery & both relatively small.

Can you do angioplasty stent on restively short 100% blockage in mid LAD and 100 % posterolateral branch of circumflex artery & both relatively small.

Generally yes: The real question is do they need to be done. An artery that has been closed for some time (cto), is usually no longer threatening to you. In some cases, with unacceptable symptoms despite appropriate meds, an attempt at opening the vessels may be considered. Ask an interventional cardiologist with experience in doing ctos to review your cath. ...Read more

How serious is an occlusion of the left circumflex artery if your heart is left-side dominant? Would an MI from that likely be fatal?

How serious is an occlusion of the left circumflex artery if your heart is left-side dominant?  Would an MI from that likely be fatal?

Serious: Left dominance means the circumflex artery supplies the major back portion of the heart rather than the right artery So occlusion of this artery compromise a large area of heart muscle that can lead to death by fatal arrhythmia or by heart failure ...Read more

Will a 3-D MRI show blockage in the proximal and distal circumflex arteries; also, the level of RCA disease? Murrell

Will a 3-D MRI show blockage in the proximal and distal circumflex arteries; also, the level of RCA disease? Murrell

MRI or MRA? CTA angi: The question's somewhat vague. Are you asking about 3-D vs. 2-D MRI? Or MRI vs. MRA (Magnetic resonance angiogram)? MRI can show changes in tissue that are effects of arterial blockage. The actual arteries themselves are seen by MRA. The size of artery blocked determines whether or not it can be seen. More proximal = larger artery = easier to see blockage. The heart moves, & MRI pics often blurry. ...Read more

Can there be a specific medical test to determine blockage in arteries?

Location?: The best test for detecting blockage in your arteries depends on the location of the blockage. Ultrasound can be used to detect blockage in the carotid (neck) and leg arteries, for example. ...Read more
