Endomyocardial biopsy (EMB) is a valuable method for diagnosing a range of cardiac conditions, but there is a risk of complication due to its invasive nature. Researchers have now found a way to combine right ventricular (RV) septal EMB, exploiting the benefit of 3D curved conduction system pacing (CSP) sheaths, with subsequent cardiac implantable electronic device (CIED, devices like pacemakers or defibrillators to regulate heart rhythm) implantation, using the same sheath.
