How often do cardiac ablation surgeries result in complications requiring pacemakers implantation?

How often do cardiac ablation surgeries result in complications requiring pacemakers implantation?

It depends: It depends on the ablation type: almost never for wpw, atrial fibrillation/flutter or ventricular tachycardia; 1% or less for avnrt (atrioventricular nodal reentry tachycardia). In avnrt, there is an extra 'lane' in the av node that conducts electrical impulses leading to tachycardia and the ablation can unintentionally damage the whole av node resulting in heart block and need for pacemaker. ...Read more

Pacemaker (Definition)

A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more

I can't decide: implantable cardioverter defibrillator or heart bypass surgery?

I can't decide: implantable cardioverter defibrillator or heart bypass surgery?

Different things: Bypass surgery (CABG) treats the blockages in the heart vessels, while the defibrillator (icd) treats dangerous heart beats such as ventricular tachycardia or fibrillation. A person may need both, depending on their medical condition. ...Read more

Is an implantable cardioverter defibrillator removed in heart bypass surgery?

Is an implantable cardioverter defibrillator removed in heart bypass surgery?

No: The defib. Device is implatnted in the inner chambers of the heart and bypass is on the out side of the heart where the coronary arteries lie.Unless theres another reason to remove the device ie an infection the device is left in. ...Read more

Risks during the ablation and pacemaker implantation?

Risks during the ablation and pacemaker implantation?

Risks of ablation: Mostly the risks are the same as for other procedures, including infection and bleeding, but also rhythm disturbances of the heart and the development of fluid around the heart. In addition, the risks for pacemakers include pneumothorax or the presence of air around the lung. These are usually safe procedures which are performed by trained cardiologists. ...Read more

Are there aortic valve repair surgeries that don't replace the valve with an artificial one?

Are there aortic valve repair surgeries that don't replace the valve with an artificial one?

Yes: There are several operations that in fact repair the aortic valve or preserve the native valve tissue while replacing the diseased aorta where the valve attaches. ...Read more

Are artificial valves better than animal valves for replacement operations?

Are artificial valves better than animal valves for replacement operations?

Depends: Not a straightforward answer since it would depend on the valve needing replacement, the degree of injury, and type of valve to be used. Often mechanical valves need longer and more intense anti-coagulation to keep them going. Best to discuss options with the cardiac surgery team contemplating the procedure. ...Read more

What are the risks and benefits of stenting diseased blood vessels / heart bypass surgery / heart transplant / artificial heart valve transplant?

Way too complex: This question is way to complex for a short text Q&A. Individual patient information is needed to really discuss risks and benefits. This discussion needs to be with a live cardiologist and/or cardiac surgeon. ...Read more

How safe are artificial heart valves?

How safe are artificial heart valves?

Analyse risk/benefit: Artificial heart valves came on the medical scene in 1961. Prior to these life savers, open heart surgeons could repair damaged heart valves. A valve repair might last 1 to 6 years. The question you need answered is... Without a heart valve how will my health be? From that point you can get the risk of implanting and maintaining your new valve. Take a friend/family with you to help decide. ...Read more

Can pacemaker fix all cases of atrial fibrillations?

No: Atrial fibrillation is an irregular heartbeat of the upper chambers of the heart. Its greatest danger is the formation of bloodclots within the heart which can trravel up to the brain and cause a stroke. Patients with af are generally treated with anticoagulants or blood thinners like aspirin, warfarin (coumadin) or dabigatran (pradaxa) to prevent strokes and medication to control the heart rate. ...Read more

Complications from having open heart surgery and getting aortic valve replacement?

There are several: The complications of aortic valve replacement include bleeding, blood transfusions, stroke, infection, renal failure, reoperation, atrial fibrillation and death. Therre are more as well. Fortunately the risks of aortic valve surgery are relatively small for most patients. The exact risks vary from patient to patient. The average risk of death is about 1-2% for most aortic valve replacements. ...Read more

What are fixed rate pacemaker and demand type pacemaker?

What are fixed rate pacemaker and demand type pacemaker?

Pacemakers: Fixed rate pacemakers stimulate the heart to beat all the time at a specified rate. Demand pacemakers only pace the heart if the rate falls below a certain set rate or irregularity in heartbeat occurs. ...Read more

Warfarin user refused neck surgery too dangerous need warfarin friendly pain management medicine artificial aorotic heart valve?

Second Opinion: This is not an unusual problem. You cam be transitioned to another anti-coagulant with the help of your cardiologist prior to the operation. The surgeon can then do the surgery and you can be placed back on your coumadin (warfarin). Discuss with your cardiologist about recommendations for another surgeon. ...Read more
