Artificial Pacemaker Risks
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
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
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 moreSee 1 more doctor answer
What are the risks and benefits of stenting diseased blood vessels / heart bypass surgery / heart transplant / artificial heart valve transplant?
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 moreSee 1 more doctor answer

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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
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 moreSee 3 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 3 more doctor answers
