[Right endoventricular biopsy using the femoral percutaneous approach: a simple procedure, harmless, reliable and repetitive. Modification of the Konno technic]

The technique of right endoventricular biopsy by femoral percutaneous path is described based on 300 incident-free samples. Ability to multiply and then repeat sampling supports a method which can be performed at the same time as examination of the conduction channels. This is of diagnostic, prognostic, therapeutic and research interest.
