TAVI: complex vascular access
17 Nov 2025 – From PCR London Valves 2025
This session addresses the challenges of complex vascular access in transcatheter aortic valve implantation (TAVI). It discusses strategies for navigating difficult thoraco-abdominal aortic anatomies, managing double aortic arches, and overcoming hostile femoral access. Case studies illustrate meticulous planning and innovative solutions essential for successful TAVI in...
TAVI: challenging anatomies
17 Nov 2025 – From PCR London Valves 2025
This session explores the management of challenging anatomical conditions in TAVI procedures. Topics include strategies for difficult self-expandable valve delivery angles, addressing complications occurring during and after TAVI, and approaches for patients with severe kyphosis or complex structural abnormalities such as aneurysms and septal anomalies.
Challenging tricuspid TEER
16 Nov 2025 – From PCR London Valves 2025
This session focuses on the intricacies of transcatheter tricuspid edge-to-edge repair (TEER) addressing iatrogenic tricuspid regurgitation, failed surgical valve repair, and approaches for patients unsuitable for valve replacement. It also examines the management of multiple clip detachments and the procedural nuances required to navigate complex tricuspid...
Clinical impact of mechanical circulatory support
22 May 2025 – From EuroPCR 2025
Explore the clinical impact of mechanical circulatory support through a series of detailed presentations covering protocols and training effects on outcomes in left-sided micro-axial flow-supported shock patients, practice variations between Sweden and the U.S., six-month outcomes post coronary intervention with VA-ECMO, and the prognostic value of...
Peripheral interventions: the hidden key for complications
22 May 2025 – From EuroPCR 2025
Uncover the critical role of peripheral interventions in managing complications. This session shares case stories of lost stents, unusual TAVI access complications, percutaneous removal of misplaced devices, revascularisation of iatrogenic pseudoaneurysms, and challenges when multiple closure devices are insufficient.
TAV-in-TAV complications
21 May 2025 – From EuroPCR 2025
Focus on the complexities and challenges of TAV-in-TAV procedures in this session. Topics include planning valve-in-valve TAVI for aortic bioprosthetic valve regurgitation, managing anatomical challenges such as left ventricular outflow tract calcium and large annulus, and addressing severe bicuspid valve stenosis with impaired ventricular function. The...
Non-antiplatelet drugs interventionalists should be aware of
21 May 2025 – From EuroPCR 2025
Gain essential knowledge on non-antiplatelet drugs relevant to interventional cardiology. Topics include the effects of empagliflozin on oxidative stress, the impact of midazolam on radial spasm during primary PCI, pharmacological cocktails to prevent radial spasm, and hydration strategies in patients with kidney disease during cardiac catheterisation.
