A compressible regurgitation drum lets a large-diameter tricuspid valve deploy through the vena cava without an oversized catheter.
Selected current sources steer pacing pulses through a multi-pole lead to improve cardiac capture while limiting energy use and unwanted tissue stimulation.
Wireless sensing coordinates leadless stimulation and defibrillation for safer cardiac therapy.
This case uses coincident pacing near the His bundle to correct Brugada conduction abnormalities with multimodal waveforms.
