Despite demonstrating better patient safety, acceptance of TRA as an access site of choice has remained low, with geographical variations. One of the relative contraindications to performing PCI through TRA is an abnormal Allen’s test (AT), in which…
Patients with atrial fibrillation and contraindications to anticoagulation have limited options for left atrial appendage (LAA) closure until approval of dedicated closure devices; off-label use of available cardiac devices represents one option. Thi…
We conducted a retrospective investigation of all TRIs performed at Sendai Kousei Hospital from January 2004 to December 2013 to evaluate the efficacy and safety of sheathless TRI in a large population (n=9658).
This study investigates the relationship of OCT-derived intrastent lumen dimensions and FFR-derived hemodynamic relevance immediately after stent implantation and evaluates the clinical impact of these parameters at follow-up. Post-stenting FFR and O…
Peripheral vascular interventions have been traditionally performed in the inpatient setting. We evaluate the safety and efficacy of peripheral vascular interventions performed in a private outpatient catheterization laboratory by performing a retros…
This study compares both the feasibility and outcomes of “off-label” transcatheter aortic valve replacement (TAVR) patients (n=156) with a standard “on-label” TAVR population (n=435) at a single institution. 
Use of the retrograde approach significantly improves the success rate of chronic total occlusion (CTO) percutaneous coronary intervention. We describe the “tip-in” technique, which involves intubation of the retrograde guidewire with an antegrade mi…
We describe the new Viabahn-in-Viabahn technique for treating acute stent-graft thrombosis by “relining” the thrombosed graft with a second stent-graft. Ten patients were treated with this technique and have been free of any repeat intervention for u…
We describe the case of a patient with NSTEMI where oral clopidogrel loading prior to PCI was directly visualized on angiography, implying a very low likelihood of adequate absorption or antiplatelet effect. This observation raises the concern that d…
The authors provide their insights on the Allen’s test and its lack of clinical usefulness in transradial interventions, and expound on whether or not a randomized trial is truly necessary to decide the issue.
