title: Loeffler endocarditis: silent right ventricular myocardium!
abstract: We present the case of a 54-year-old male patient with Loeffler endocarditis. It is a rare disorder characterized by fibrous thickening of the endocardium leading to apical obliteration and restrictive cardiomyopathy resulting in heart failure, thromboembolic events or atrial fibrillation. To the best of our knowledge, this is the first case reporting the electrical silence of the right ventricular (RV) apex caused by fibrothrombotic thickening of this area. Under these circumstances RV apical implantation of an implantable cardioverter defibrillator (ICD) or pacemaker electrode may lead to unsuccessful stimulation of these devices.
