<unk>  of the right ventricle via the internal jugular vein is standard after heart transplant. A bioptome is used to gain access to the heart via a sheath inserted into the right internal jugular or less commonly the femoral vein. Monitoring during the procedure consists of performing ECGs and blood pressures. Guidance and confirmation of correct positioning of the bioptome is made by echocardiography or fluoroscopy before the<unk>  specimen is taken and in the case of transplants, usually three or four or more samples are taken.<unk>  fibrosis can occur if<unk> es are performed repeatedly. This risk is reduced if the operator is experienced. Unlike for rejection detection, for diagnosing heart disease, different<unk>  sites within the heart are targeted. It is possible but less common to<unk>  the left ventricle via the femoral arteries.
