Left Circumflex Artery Blockage
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?
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
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.
When 100% blockage in mid LAD and 100 % posterolateral branch of circumflex artery & both relatively small. What that means. Would it hinder bcag.
Yes: Smaller targets can be a challenge. But we can do coronary artery by bass grafting CABG for most.See 1 more doctor answer
Have relatively short 100% blockage in mid LAD &100% posterolateral branch of circumflex artery (both relatively small targets).Will stent help or ris?
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.See 1 more doctor answer
My mother had CABG surgery but the surgeon was unable to bypass left circumflex lcx artery 90% block. Rest 2 were bypassed. What is the risk for lcx?
Depends: It depends on the particular anatomy of the branches from that part of the left coronary artery to the back of the heart. Small blood vessel branches will not keep bypass grafts open because the flow through them is insufficient. Collateral (feeding) branches from other adjacent arteries may feed that area. In some cases, angioplasty (ballooning) with stents could be considered.
Middle LAD & circumflex artery are 100% blocked. Blockages, while severe, short in length. Both arteries receive collateral. Can angioplasty/stent help?
Yes if symptoms: From ischemia are not responsive to medical therapy.
I have 100% blocked circumflex artery and all other arteries are reassuringly normal with heart muscle intact, what are the complications in my case?
See below: Keep the BP and the lipids to ideal levels. Do not smoke, so u would not have any complications!
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.
Carotid blockage: If asymptomatic with use of proper medical therapy a moderate carotid blockage is fairly low risk. Many vascular surgeons would favor no intervention in this situation. If symptomatic, would recommend repair of this. Options include stenting or open surgery, carotid endarterectomy. Best data suggests that stenting over age 65 -70 has higher risk of stroke than endarterectomy.See 2 more doctor answers
My dad had a CABG in 2008. In 2013, during yearly checkup, the angiogram indicated 70% blockage of the left circumplex artery. Should he redo CABG?
No: Circumflex is seldom a reason for single bypass or redo. Also seventy % is borderline for angioplasty or stent unless other methods show it is flow limiting (ultrasound or pressure wire)
I have 69% blockage in the left carotid artery. I also have dizzy fainting spells. What should I do?
Be evaluated: A 69% carotid artery blockage on one side isn't enough to cause dizziness/ fainting spells. Is it low blood pressure, anemia, a middle ear problem? It's best to have your internist work through the possible causes. With regard to your cerebral circulation, it would be helpful to know how your vertebral arteries look. A simple ultrasound can evaluate these arteries which supply the balance center.See 1 more doctor answer
What part of the heart would receive less blood if the were a blockage in the left main coronary artery?
Left main: Most of the blood to the left ventricle passes thru the left main. That is why it is such a serious lesion.
I am going in for a blockage on my right kidney I am stage 4 renal failure w/ coranary artery disease and am going in for a surgical procedure remove a 60% blockage on my right kidney and 2 large stones on my left how serious is this procedure
Very important: Most important is to understand that with stage 4 renal failure and coronary artery disease you are fairly likely to develop kidney failure in the future. The question is how long. Your job is to address factors in your control such as weight, blood sugar, blood pressure, medications, smoking. The procedure sounds like it is not "open", and will use balloons + lithotripsy. Some risk but reasonable.See 1 more doctor answer
What do you recommend if I had a heart angiogram with 70% blockage in my left main coronary artery. No stint. Dr afraid he would block. Why?
Bypass surgery: Everything is a balance between risk/benefit. Often with a > 50% left main blockage, a bypass surgery is the safest choice. Medical therapy alone carries a high risk of sudden death due to the severity of the blockage. A stent placement there, though relatively simple - might have a catastrophic outcome if any slight thing went wrong. A stent is indicated if surgery is higher than usual risk.
I have been occasionally waking up with dim vision in left eye. I have a 60% blockage of my carotid artery on the left. Could this be the cause?
Maybe: Amaurosis fugax is what you are referring to. The plaque in the carotid artery can shed particulate matter upstream, and when this enters the artery going to the same side eye, typical symptom of "shade coming over the eye" is experienced. Visiting an eye doctor may help make this diagnosis.See 2 more doctor answers
Would left coronary artery blockage produce ischemia of left ventricle and right axis deviation on ekg?
It could: You should discuss this with your doctor to see how severe the ischemia is and w to manage it
