Abstract
Transcatheter aortic valve implantation (TAVI) was originally devised as a treatment for patients with aortic stenosis (AS). It has since emerged as a beneficial alternative to surgical aortic valve replacement (SAVR), extending its reach to a broader array of patients. Our objective was to illustrate the developmental trends and focus areas in TAVI research. We sourced a total of 11,480 research papers on TAVI, published between 1994 and 2022, from the Web of Science Core Collection (WoSCC) database. We conducted a bibliometric analysis of these publications, generating cooperation maps, performing co-citation analysis of journals and references, and carrying out a cluster analysis of keywords. Our findings indicate that TAVI research grapples with numerous clinical challenges. We created knowledge maps that highlight contributing countries/institutions, authors, journals with high publication and citation rates, and notable references in this domain. North America and Europe have been at the forefront of research within the TAVI field. The institutions and authors from these regions exert significant influence in this area of study. Beginning in 2009, China has progressively expanded its research on TAVI over the past two decades. We anticipate that future research will increasingly focus on three key areas: implementation scope, lifelong management, outcomes and predicting the risk of TAVI. Research on TAVI is flourishing. Cooperation among different countries and institutions in this field must be strengthened in the future, especially for developing counties.

J Card Surg 2022; 37:1263-1271. [PMID: 35179249 DOI: 10.1111/jocs.16335] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 01/11/2022] [Accepted: 01/19/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND The aim of this study was to analyze perioperative results and long-term survival of re-sternotomy for surgical aortic valve replacement (SAVR) in octogenarians in age of transcatheter therapies. METHODS This is a retrospective, single-center study (April 2000 to December 2019). Perioperative data were compared for re-sternotomy with isolated SAVR (Isolated redoSAVR) and re-sternotomy with SAVR and concomitant cardiac procedure (Associated redoSAVR). Regression analyses were performed to identify predictors of in-patient mortality. Hazard ratios and Kaplan-Meier survival curves were compared for groups. RESULTS There were 163 patients (Isolated redoSAVR; 69, Associated redoSAVR; 94). Emergency/salvage cases were excluded. The median age was 83 (81-85) years and the median logEuroSCORE was 19.2 (13.0-26.7)%. The follow-up was 4.2 ± 3.5 years. Inpatient mortality was 4.9% (1.4% vs. 7.4% for Isolated redoSAVR and Associated redoSAVR respectively, p = .08). TIA/stroke rate was 8% (9% vs. 7% for Isolated redoSAVR and Associated redoSAVR, respectively, p = .78). COPD was a predictor of inpatient mortality (odds ratio: 8.86; 95% confidence interval: 1.19-66.11, p = .03). Survival was 88.7%, 86.4%, 70.1%, 49.5%, and 26.3% at 1, 2, 5, 7, and 10 years. There was no survival difference between Isolated redoSAVR and Associated redoSAVR (log rank p = .36, Wilcoxon p = .84). Significant adverse predictors of long-term survival were COPD, postoperative TIA/stroke, and length of stay. Survival was lower than age and gender-matched first-time SAVR and general population of the United Kingdom. CONCLUSION RedoSAVR in octogenarians is associated with significant morbidity and mortality. Shared decision-making should consider emerging transcatheter therapies as a valuable option in selected patients.

IJC HEART & VASCULATURE 2019; 23:100375.

Abstract
TAVR has become the standard treatment in patients at increased surgical risk (STS or EuroSCORE II ≥4% or logistic EuroSCORE I ≥ 10% or other risk factors not included in these scores such as frailty, porcelain aorta, sequelae of chest radiation) and it is increasingly being performed in patients at intermediate to low (STS or EuroSCORE II <4% or logistic EuroSCORE I < 10%) surgical risk. Although non-inferiority has been demonstrated in intermediate and low-risk patients, several challenges need to be addressed before expansion to younger patients. Current trends, trials results, and remaining challenges are summarized and discussed in this review.

Abstract
Survival of symptomatic patients with severe aortic stenosis (AS) is very poor, with an average mortality reaching up to 2% per month. Approach to diagnosis and treatment of patients with AS was conservative; patients were referred to surgery only if the AS-induced symptoms become apparent and significantly limit the quality of patient' life. In the past 15 years, the novel treatment strategy in subgroups of symptomatic patients with AS have been the subject of extensive research, starting from introduction of transcatheter aortic valve implant (TAVI) in inoperable symptomatic patients with severe AS and continuing further to patients with very high and high operative risk. In the past few years, the focus has further shifted toward the patients with lower operative risk, as well as to asymptomatic patients with severe AS. In the former group, the question relates to whether TAVI is beneficial when compared to SAVR in intermediate- to low-risk patients with symptomatic AS. In the latter group, the main issue is if and when the SAVR should be performed. This article analyzes current status and evidences regarding treatment strategies in symptomatic high, intermediate, low-risk, and asymptomatic patients with isolated severe AS.
