Syncope in elderly patients--is there a place for endomyocardial biopsy?

Abstract

Syncope in the aging population has two characteristics--it always has a multifactorial origin and age by itself is a predictor of a worse outcome even in syncope with an apparent benign mechanism. Therefore, it is worthwhile investigating extensively the cardiac substrate in selected cases when the initial evaluation demonstrates its presence. In the cases where the usual workup fails to unveil the cause for the decompensating heart substrate, morphological examination with endomyocardial biopsy should be taken into account, after matching every particular case with one of the clinical scenarios listed in the Scientific Statement on the role of endomyocardial biopsy in the management of cardiovascular disease.
