Long-term follow-up of patients with cardiac sarcoidosis and implantable cardioverter-defibrillators
Heart Rhythm, 05/24/2012
Betensky BP et al. – Ventricular tachyarrhythmias requiring ICD therapy were common in patients with cardiac sarcoidosis, with an estimated incidence rate of 15% per year. Longer follow–up, left ventricular systolic dysfunction, and complete heart block were associated with VT/VF. Patients with primary prevention implantable cardioverter–defibrillators (ICDs) had high rates of appropriate ICD therapy but not as high as did secondary prevention patients. In the absence of reliable risk stratification techniques, consideration should be given to prophylactic ICD implantation in patients with cardiac sarcoidosis.
