title: Intraoperative transmural myocardial biopsy: a simple technique.
abstract: A Tru-cut disposable biopsy needle was used in 10 pigs, 3 cadavers and 63 humans to obtain transmural ventricular myocardium for diagnostic and research purposes. The technique proved simple and safe. In every case an adequate amount of full-thickness myocardium was obtained which was examined by light and electron microscopy and used for enzyme studies and glycogen measurement.
