A State-of-the-Art on transcatheter interventions for heart failure that provides an in-depth exploration of the physiology, rationale, and the current stages of clinical development of existing procedures. In Interventions for valvular disease and heart failure: direct wire pacing without the need for a temporary venous pacemaker using the Electroducer sleeve; a study on long-term changes in coronary physiology after aortic valve replacement; the impact of the timing of bioprosthetic valve fracture on the durability of transcatheter heart valves. In coronary interventions: safety and efficiency with a standardised OCT-guided workflow; coronary artery calcification with drug-eluting stents; the 5-year outcomes of the BIOFLOW-IV trial. In peripheral interventions: mechanical thrombectomy for pulmonary embolism with the FlowTriever system; and more...
