Automatic Implantable Cardiac Defibrillator (AICD) placement
The role of AICD (automatic implantable cardiac defibrillator) placement in HCM is controversial. It offers the best potential benefit for survival and should probably be implanted in survivors of SCD and those deemed at high risk by clinical parameters. Nonetheless, the impact on prognosis is unclear because tachyarrhythmias may not always be the mechanism for syncope and sudden death. In addition, older patients may be self-selected “survivors” that stand to gain less from ICD placement. One recent retrospective study showed that at an average follow-up of 128 patients at 3.1 years, 23 percent had shocks for VT (ventricular tachycardia) and 25% had inappropriate shocks. Of those receiving the ICD prophylactically, 5% were shocked per year. This study did not evaluate the role of clinical predictors, evaluate total mortality and was a non-randomized retrospective design that does not establish the need for ICD placement in all patients with HCM or superiority to amiodarone therapy.
