Challenging TAVI
09 Feb 2025 – From PCR Tokyo Valves 2025
Delve into this captivating session that explores challenging TAVI procedures. Witness the management of a patient with pure aortic regurgitation and previous mitral valve replacement, an extremely challenging transfemoral TAVI, the management of bradycardia before TAVI in a patient with MVR and TVR, a case of...
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...
TAVI in small annulus - LIVE case
08 Feb 2025 – From PCR Tokyo Valves 2025
A 79-year-old female with CAD (stenosis in the mid-LAD), asthma, and diabetes presented with symptomatic severe aortic stenosis. Left ventricular function was preserved, with an annulus measuring 355 mm², and the valves were heavily calcified.
A Navitor Vision valve was implanted with predilatation (18 mm balloon) under...
TAVI and future coronary access - LIVE case
18 Feb 2024 – From PCR Tokyo Valves 2024
An 81-year-old woman, with a history of breast cancer surgery, stroke, and lymphoma remission, presented a severe symptomatic aortic stenosis associated with a suspicion of right coronary artery disease on the CT. The operators decided to perform TAVI first and then control the RCA by angiography...
