What patients should get an implantable cardioverter-defibrillator (icd) for heart failure?

New Guidelines. This is somewhat complex and will not all fit in 400 characters so I am creating initials. 1. Ischemic cardiomyopathy, i.C., with ejection fraction, ef, >30% but <35%, newyork heartassoc, nyha, class ii or iii, and >30 days post mi/revascularization. 2. Ic, ef <30%. 3. Ic, ef between 36-40% with inducible ventricular fibrillation or tachycardia, 4. Non-ic with ef <35% and nyha class ii or greater.

What benefit does the implantable cardioverter-defibrillator give to patients who have had a cardiac arrest or heart attack?

Prevent recurrence. Depending on the reason for cardiac arrest, an automatic implantable defibrillator can be very effective in preventing a second cardiac arrest in the future.
It may prevent death. Implantable cardioverter-defibrillators (icds) are used to treat ventricular tachycardia or ventricular fibrillation, which if untreated, may cause a fatal cardiac arrest. Icds can often quickly treat these conditions before permanent brain or heart damage can be done. Icds are not used to treat or prevent heart attacks, which are a "plumbing" issue.

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.
Nope. We just turn it off so it doesn't go off during the case from cautery noise.

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

Specialist Needed. This is a type of question you should take up with a physician who specializes in heart disease. There is no answer applicable to the general population. The ansewr to this question must be individualized to you and your circumstances.
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.

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.

Can you tell me which is your experience with your implantable cardioverter-defibrillator (icd)?

ICD. Icds are implanted to monitor the electrical activity of very abnormal hearts to see if a life threatening rhythm occurs. If it detects one of these rhythms, it will charge its capacitor and fire a shock to defibrillate the heart back to stable rhythm. In appropriate patients these devices save lives.

When is an implantable cardioverter defibrillator used to treat patients with arrhythmias?

IC + EF btwn 36-40% When the patient has ischemic cardiomyopathy, ejection fraction between 36-40% with inducible ventricular fibrillation or tachycardia, .
It depends. When the risk for cardiac arrest is high enough, a physician may recommend a patient get an icd. This might be for patients with a weak heart, genetic disease (like hocm, long qt, arvd), or someone who has survived a cardiac arrest already.
Sudden cardiac death. Icd's are utilized in patients who are at risk for sudden cardiac death or ventricular arrhythmias. These can be patients who already have significant structural heart disease or may have already suffered a sudden death episode. Also they are utilized in patient's who have certain familial conditions which may predispose them to sudden death.

What patients need an implantable cardioverter defibrillator?

Ventricular Arrhythm. Patients that have dangerous arrhythmias such as ventricular tachycardia or ventricular fibrillation are the usual candidates for an implanted cardio-verter defibrillator or icd.
VT/VF, certain other. In addition to preventing dangerous ventricular arrhythmias (which can cause sudden cardiac death) in people who have had these, in certain select cases cardioverter defibrillators have use for prevention of these heart rhythms in people who are at high risk for them. This can include certain cardiomyopathies, also some cases of congestive heart failure (combined with a biventricular pacemaker).
