Relation Between Left Ventricular Outflow Tract Calcium and Mortality Following Transcatheter Aortic Valve Implantation.

Left ventricular outflow tract (LVOT) calcium is known to be associated with adverse procedural outcomes after transcatheter aortic valve implantation (TAVI), yet its effect on midterm outcomes has not been previously investigated. The aim of this study was to determine the influence of LVOT calcium on 2-year mortality after TAVI. A total of 537 consecutive patients underwent TAVI and 2 groups were established, stratified based on the severity of the LVOT calcium.

Comparison of SAPIEN 3 and SAPIEN XT transcatheter heart valve stent-frame expansion: evaluation using multi-slice computed tomography.

Aims: Stent-frame morphology of the newer-generation, balloon-expandable transcatheter heart valve (THV), the SAPIEN 3 (S3), after transcatheter aortic valve implantation (TAVI) is unknown. We evaluated the THV stent-frame morphology post TAVI of the S3 using multi-slice computed tomography (MSCT) compared with the prior-generation THV, SAPIEN XT (S-XT).

Methods And Results: A total of 94 consecutive participants of RESOLVE registry (NCT02318342) had MSCT after balloon-expandable TAVI (S3 = 39 and S-XT = 55).

Outcomes in Patients With Transcatheter Aortic Valve Replacement and Left Main Stenting: The TAVR-LM Registry.

Background: A percutaneous approach with transcatheter aortic valve replacement (TAVR) and percutaneous coronary intervention (PCI) of the left main coronary artery (LM) is frequently used in high-risk patients with coexisting aortic stenosis and LM disease. Outcomes of TAVR plus LM PCI have not been previously reported.

Objectives: The primary objective of the TAVR-LM registry is to evaluate clinical outcomes in patients undergoing TAVR plus LM PCI.

Feasibility and safety of balloon-expandable transcatheter aortic valve implantation with moderate or without predilatation.

Aims: Aortic valve preparation by performing balloon aortic valvuloplasty (BAV) has always been considered mandatory during transcatheter aortic valve implantation (TAVI) procedures. We aimed to investigate the feasibility and safety of performing balloon-expandable TAVI with moderate or with no predilatation (PD).

Methods And Results: Overall, 121 patients underwent TAVI with no PD and 392 with moderate PD.

Balloon-expandable transcatheter aortic valve replacement in patients with extreme aortic valve calcification.

Objectives: To assess the procedural and short-term clinical outcome of performing balloon-expandable TAVR in patients with extremely calcified aortic valves.

Background: Quantity of aortic valve calcification predicts rates of paravalvular regurgitation (PVR) post transcatheter aortic valve replacement (TAVR). Nonetheless, short-term outcomes of balloon-expandable TAVR in patients with extremely high calcified aortic valves have not been previously described.
