One-year outcomes of the pivotal clinical trial of a balloon-expandable transcatheter aortic valve implantation in Japanese dialysis patients
CONCLUSIONS: TAVR using SAPIEN 3 is safe and effective for the treatment of Japanese dialysis patients with symptomatic severe aortic valve stenosis.PMID:34348863 | DOI:10.1016/j.jjcc.2021.07.006

Discrepancy of Aortic Valve Area Measurements by Doppler vs. Biplane Stroke Volume Measurements and Utility of Combining the Different Areas in Aortic Valve Stenosis 　- The Asian Valve Registry.
CONCLUSIONS: Discrepancy in AVAI by Doppler vs. biplane method was significantly more pronounced with increased LV outflow tract flow velocity, shorter height, lower weight, older age and smaller LV cavity dimensions. Combining the AVAIs enabled mutual and incremental value in predicting events. PMID: 33208592 [PubMed - as supplied by publisher]

Clinical outcome after surgical aortic valve replacement in low-risk Japanese patients with severe aortic stenosis
AbstractTwo randomized control trials demonstrated that transcatheter aortic valve implantation was associated with 1 –2 year clinical outcomes comparable or even superior to surgical aortic valve replacement (SAVR) in low surgical risk patients with severe aortic stenosis (AS). However, no previous study has reported the clinical outcomes after SAVR in Japanese patients with low surgical risk. From 3815 consecu tive patients enrolled in the CURRENT AS registry, we retrieved 220 patients who underwent SAVR in reference to the inclusion and exclusion criteria of the PARTNER 3 trial. Age and surgical risk score in the cur...

Differences in Flow-Gradient Patterns Between Severe Bicuspid Aortic Stenosis and Severe Tricuspid Aortic Stenosis 　- Mechanistic Insight From Multimodal Imaging.
CONCLUSIONS: Flow-gradient patterns in bicuspid AS differ from those of tricuspid AS and are associated with the structural and functional characteristics of the aorta. PMID: 31787664 [PubMed - as supplied by publisher]

Cerebral Infarction after Transcatheter Aortic Valve Implantation in Japan: Retrospective Analysis at a Single High-Volume Center
Perioperative cerebral infarction is one of the concerning complications after transcatheter aortic valve implantation in patients with aortic stenosis. Several studies have reported on this complication; however, those included only Caucasians and analyzed a small number of cases. Here, we report on the characteristics and risk factors of symptomatic cerebral infarction after transcatheter aortic valve implantation in a single, high-volume center in Japan.

DangasTranscatheter aortic valve implantation, also called transcatheter aortic valve replacement (TAVR), is the treatment of choice for patients with severe aortic stenosis and intermediate to high operative risk. A significant portion of TAVR patients have atrial fibrillation (AF) requiring chronic oral anticoagulation. In moderate...

Prognostic value of paradoxical low-gradient severe aortic stenosis in Japan: Japanese Multicenter Aortic Stenosis Study, Retrospective (JUST-R) Registry.
CONCLUSIONS: In Japanese patients, the prognoses of PLG-SAS and PLFLG-SAS were better than that of HG-SAS and similar to that of MAS, being better than that in Western populations. PMID: 25687368 [PubMed - as supplied by publisher]

The Case Files: When a Spade is Not a Spade
Turrin, Danielle DO; Sattler, Steven DO; Amodeo, Dana DO A 25-year-old Hispanic man presented to the emergency department with a complaint of three days of left-sided precordial chest pain. He described the pain as a constant 6/10 with pressure-like discomfort radiating to his left arm and the left side of his neck. He also experienced nausea, but denied any provocative or palliative factors. He said he had not experienced anything similar to this before. He had no family history of heart disease, acute myocardial infarction, or sudden cardiac death. He admitted to a 1.5 pack-per-day smoking history and social alcohol us...
