Angiogram and heart stent the same thing?

Angiogram and heart stent the same thing?

No: They are often performed at the same time, but the angiogram is much safer, just injecting liquid dye into the artery (a diagnostic procedure). The stent is a therapeutic procedure that is higher risk of complications (death, bleeding, heart attack, and stroke). ...Read more

How does the rate of restenosis of coronary arteries compare with medical therapy over stents?

How does the  rate of restenosis of coronary arteries compare with medical therapy over stents?

Not sure: I am not sure what is meant here. If there was no stent or balloon angioplasty to begin with, the term "restenosis" is sort of irrelevant here. On the other hand, if one is talking about treating in-instent restenosis with medical therapy; if the patient is asymptomatic, there is no reason to not try medical therapy for a while at least. ...Read more

Can cardiac ablation for atrial fibrillation cause damage to the coronary arteries close to the ablation site

Can cardiac ablation for atrial fibrillation cause damage to the coronary arteries close to the ablation site

Yes but it's rare: The coronary arteries, most specifically a branch of the left circumflex artery run directly beneath a structure called the left atrial appendage. Ablation in that region, or just behind it puts rf energy near that artery. However, the artery has very high flow (relatively speaking) and is thus protected from damage the majority of the time. ...Read more

Is there ensurance of no heart attack after bypass surgery of heart for 80% blockage on all vessels?

Is there ensurance of no heart attack after bypass surgery of heart for 80% blockage on all vessels?

No: At one operation, we fix all we can. Some people persist with the same high risk behaviors. Future blockage can occur in the native arteries or the grafts. No guarantee, but good results. ...Read more

Does a quadruple bypass treat all the major heart arteries?

Does a quadruple bypass treat all the major heart  arteries?

Possibly: Although there are three main coronary arteries, these arteries themselves may have significant branches that themselves may need bypassing. So 4 grafts do not necessarily treat all the major arteries, but will treat the 4 that are blocked. ...Read more

Catheter Angiography of Heart for Mitral Valve Prolapse. Cardiologist said all Artery's are very good . would this mean the Carotid Artery's also?

Catheter Angiography of Heart for Mitral Valve
Prolapse. Cardiologist said all Artery's are very good .
would this mean the Carotid Artery's also?

Very likely: There is a good correlation between coronary artery disease and carotid artery disease - almost 60% . So a normal coronary artery is likely to indicate a low probability of carotid artery disease. If you absolutely need to know you can get a simple carotid artery ultrasound .( this is a non invasive simple test) ...Read more

What is likelyhood of having heart attack or angina after angioplasty (balloon) & stent placed on main artery?

What is likelyhood of having heart attack or angina after angioplasty (balloon) & stent placed on main artery?

Angioplasty/stent : Heart attack is not necessarily prevented by angioplasty or stent. We do treat the underlying disease aggressively as well as dual anti platelet therapy to prevent stent thrombosis. If you smoke it negates much of the treatment. Most people do well after angioplasty and stenting. ...Read more

What are the risks with regards to angioplasty for angina after bypass?

What are the risks with regards to angioplasty for angina after bypass?

Several: Depends on what vessel? A graft an unbypassed native artery whatever is thought to be instrumental to the angina symptom how long since the bypasses? If the bypases are open and generally perfusing the major coronaries the risk should be quite low. If not, the usual risks of dissecting, clotting, embolizing a vessel or graft are there. The general list is; death bleeding, recurrence, stroke. ...Read more

If it is symptomatic (angina) medicines such as nitroglycerin, beta-blockers, and sometimes calcium channel blockers can be used. ...Read more
