SummaryAs Japan has one of the most rapidly aging populations in the world, transcatheter aortic valve implantation (TAVI) is likely to be performed in increasing numbers of older people. There is little information on either the efficacy or the safety of TAVI in nonagenarians in Asia.From October 2013 to June 2015, 112 consecutive patients underwent TAVI with Edwards SAPIEN XT valves in our institution. We compared 25 patients aged at least 90 years (mean 91.6 ± 1.7 years) with 87 patients aged under 90 years (mean 82.5 ± 6.0 years) at the time of TAVI. All definitions of clinical endpoints and adverse events were based on the Valve Academic Research Consortium 2 definitions.The median follow-up interval was 561.5 days (the first and third quarters, 405.0 and 735.8 days). Nonagenarians had a higher logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE), Euro II score, and the Society of Thoracic Surgeons predictive risk of mortality (STS) score, and a prevalence of clinical frailty scale !4. The rate of device success, and the 30-day and 6-month mortalities were not different between patients aged !90 years and < 90 years (96.0% versus 92.0%, P = 0.68; both 0%, P = 1.00; 4.0% versus 3.5%, P = 0.32, respectively). At six months, clinical efficacy and time-related valve safety were also similar in the two groups (12.5% versus 13.4%, P = 1.00; 4.5% versus 10.3%, P = 0.68, respectively). The cumulative 1-year mortalities were not significantly different between the two groups (8.4% versus 9.4%, P = 0.94, respectively).TAVI can contribute to acceptable clinical results and benefits in a carefully selected group of nonagenarians in Asia.(Int Heart J 2017; 58: 900-907)

Background The usefulness of preprocedural nutritional status to stratify prognosis after transcatheter aortic valve implantation has been evaluated; however, the studies conducted so far have been relatively small and/or focused on a single nutritional index. This study sought to assess the prevalence and prognostic impact of malnutrition in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation. Methods and Results We applied the Controlling Nutritional Status score, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index to 1040 consecutive older Japanese patients at high surgical risk who underwent transcatheter aortic valve implantation. According to the Controlling Nutritional Status score, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index, 16.6%, 60.5%, and 13.8% patients had moderate or severe malnutrition, respectively; 89.3% were at least mildly malnourished by at least 1 score. Worse nutritional status was associated with older age, lower body mass index, higher degree of frailty, worse symptoms and renal function, atrial fibrillation, and anemia. During a median follow‐up of 986 days (interquartile range, 556–1402 days), 273 (26.3%) patients died. Compared with normal nutrition, malnutrition was associated with an increased risk for all‐cause death (adjusted hazard ratio for moderate and severe malnutrition, respectively: 2.19 (95% CI, 1.45–3.31; P <0.001) and 6.13 (95% CI, 2.75–13.70; P <0.001) for the Controlling Nutritional Status score, 2.02 (95% CI, 1.36–3.02; P =0.001) and 3.24 (95% CI, 1.86–5.65; P <0.001) for the Geriatric Nutritional Risk Index, and 1.60 (95% CI, 1.06–2.39; P =0.024) and 2.32 (95% CI, 1.50–3.60; P <0.001) for the Prognostic Nutritional Index). Conclusions Malnutrition is common in patients undergoing transcatheter aortic valve implantation and is associated with increased mortality.

MEP monitoring was not significantly associated with motor deficits at discharge.

The sensitivity of CBF in CO2 remained but CMRO2 was reduced markedly in COPD patients.
