Tricuspid and pulmonary valve intervention
09 Feb 2025 – From PCR Tokyo Valves 2025
Delve into the challenges and innovations in tricuspid and pulmonary valve interventions. Discover cases involving imaging nightmares for treating severe tricuspid regurgitation, transcatheter pulmonary valve implantation for heavily calcified lesions, and the use of the "zipping technique" for massive tricuspid valve flail gaps. Explore the strategies...

26 Nov 2024 – From PCR London Valves 2024
Explore this session featuring a selection of compelling clinical cases from PCR London Valves 2024, focusing on innovative percutaneous interventions for complex pulmonary valve pathologies. Discover how clinicians are simplifying the challenge of treating dilated main pulmonary arteries, dealing with premature balloon rupture, and tackling giant...
TAVI in bicuspid stenosis: complex situations
14 May 2024 – From EuroPCR 2024
This session comprises selected clinical case submissions focused on TAVI (Transcatheter Aortic Valve Implantation) in patients with bicuspid aortic stenosis. Participants will learn about complex scenarios, including fusion raphe, hostile bicuspid anatomy, large annulus, and early TAVR dysfunction. The session features case presentations followed by audience...
TAVI in bicuspid anatomy
18 Feb 2024 – From PCR Tokyo Valves 2024
Delve into the complexities of TAVI within bicuspid anatomy through this selection of cases: learn about the challenges and techniques involved in overcoming the horizontal aorta, explore how to size the transcatheter aortic valve in severely calcified bicuspid anatomy, and more!
Learn the procedure strategy - Lifetime management of aortic stenosis therapy with self-expandable valve
17 Feb 2024 – From PCR Tokyo Valves 2024
This special session sponsored by Medtronic focuses on learning what characteristic valves should be used to treat aortic stenosis patients with low calcification or with extremely small native aortic annuluses, and what to pay attention to during the procedure.
Prevention and treatment of left ventricular outflow tract obstruction
19 Nov 2023 – From PCR London Valves 2023
Explore intriguing cases in this session and gain a deeper understanding of preventing and managing LVOT obstruction: uncover innovative approaches such as Valve-in-Valve TMVR with Lampoon, learn about the nuances of TMVR after re-section of the anterior leaflet, and more!
