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

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

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

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

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

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

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

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 can be done for implantable cardioverter defibrillator versus heart bypass surgery?

What can be done for implantable cardioverter defibrillator versus heart bypass surgery?

Different indication: Aicd for arrhythmias and ventricular tachycardia and does not revascularize. Bypass for coronary blockage (which can have arrhythmias) to improve circulation and sometimes stops arrhythmias induced by ischemia- low flow. ...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

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

Are there additional risks to having an artificial heart over a natural heart?

Are there additional risks to having an artificial heart over a natural heart?

Blood clots can form: All artificial surfaces are more likely to cause blood to clot than the natural lining (called endothelium) of blood vessels or the heart. If a clot forms in the heart, a piece may break off + travel to the brain, causing a stroke. To prevent clotting, blood thinners are used with an artificial heart, + there is risk of bleeding. Natural is always better than artificial, if there is a choice. ...Read more

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

Is it common to remove an implantable cardioverter defibrillator during heart bypass surgery?

Is it common to remove an implantable cardioverter defibrillator during heart bypass surgery?

No: It was put in for a reason so unless something has changed, it will ordinarily be left in place unless the battery is failing, in which case it would be replaced. ...Read more

Are there alternatives to an implantable cardioverter-defibrillator?

Are there alternatives to an implantable cardioverter-defibrillator?

Usually not: The indications for icd placement indicate it should not be performed if there is are reversible causes. In all of the trials comparing icd therapy to alternatives in the absence of a reversible cause, the outcome with icd was much better. ...Read more

How are eecp & heart bypass surgery different?

How are eecp & heart bypass surgery  different?

Both for angina: They're both for angina. Bypass is a major open chest surgery. Eecp is non-invasive. Bypass provides lasting benefit and, in carefully selected patients, improves life expectancy. Neither is true for eecp. ...Read more

What things interfere with pacemakers and implantable defibrillators?

What things interfere with pacemakers and implantable defibrillators?

Not much: Common household appliances and cellular phones are generally safe to use near an implantable defibrillator. It is best to avoid sources of significant electric current. For example, you should keep your icd 2 feet from an arc welder. You should not lean over your car engine while it is running. It is best to also keep large magnets off your device as well since this can affect its performance. ...Read more

Bypass heart surgery risks?

Bypass heart surgery risks?

Many but uncommon: Bypass surgery is major surgery. There are risks although the majority of patients don't get them or at most one. Rhythm disturbances, bleeding, and infection are the commonest. Congestive failure, collapsed lung, torn sternal wire from coughing occasionally occur. Nerve damage, stroke, heart attack, death are rare but sometimes occur (<1-2% generally). ...Read more

Are there any risks or side effects to multifocal lens implant surgery?

Are there any risks or side effects to multifocal lens implant surgery?

Multifocal IOL risks: MIOLs have many advantages: improve the reading, distance, & intermediate vision in the vast majority of patients (assuming macula, optic nerve, brain are functioning normally). Halos, glare (usually improves with time), need for reading glasses/distance Rx from residual astigmatism biggest risk after MIOLs aside from general surgery risks. ...Read more
