Endothelialization of an Amplatzer Septal Occluder Device 6 Months Post Implantation: Is This Enough Time? An In Vivo Angioscopic Assessment

Shingo Kuwata , MD, PhD;

We describe a cut-down method that is useful in cases with calcification restricted to the region surrounding the puncture site in transcatheter aortic valve implantation patients with severe aortic stenosis.

We describe a cut-down method...

(A) Angioscopic system evaluating surface of the atrial septal occluder (ASO): low-molecular-weight dextran is infused from the guiding catheter and the tip of the GuideLiner extension catheter during observation. (B) Neointima covering most of the 22 mm ASO 6 months post implantation. (C) Around the central part of the device, the struts were exposed with marked thrombus formation. Guidewire marked by asterisks (*) in panels B and C.

Comparison in Clinical Outcomes Between Leadless and Conventional Transvenous Pacemaker Following Transcatheter Aortic Valve Implantation

This report evaluates endothelialization in vivo and demonstrates that 6 months of postimplantation prophylactic therapy may not provide sufficient time for adequate endothelialization.

This report evaluates...

Comparison in Clinical Outcomes Between Leadless and Conventional Transvenous Pacemaker Following Transcatheter Aortic Valve Implantation

Toshiki Kaihara , MD, PhD;

Patients with leadless PM following TAVI may have shorter hospital stays, and clinical outcomes can be comparable with DDD-PMs.

Patients with leadless PM...
