[PMID: 38788303 DOI: 10.1016/j.hrtlng.2024.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 05/10/2024] [Accepted: 05/10/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND Transcatheter aortic valve replacement (TAVR) is a preferred treatment for patients with highly critical aortic stenosis (AS), which is a difficult and complicated procedure, leaving a heavy economical burden on patients and national health insurance. Minimalist TAVR can simplify a part of the operation procedures, but the surgical efficacy and safety are still under debated. OBJECTIVES Explore the effectiveness and safety of minimalist TAVR in the treatment of patients with aortic stenosis. METHODS A systematic search of PubMed, Web of Science, and Embase databases was conducted for studies involving application of minimalist TAVR in patients with severe aortic stenosis, two researchers independently screened the literature, extracted data and Meta-analysis was performed using STATA 16.0 software. RESULTS Nine studies, involving a total of 3,148 AS patients, were included. Minimalist TAVR has similar surgical success rates compared to standardized TAVR, intraoperative fluoroscopy time, dosage of contrast agent, and total operative time were superior to standard TAVR. Regarding surgical complications, the incidence of permanent pacemaker placement and moderate to severe paravalvular leakage were similar for both TAVR, the risk of major vascular complications and major bleeding events in the minimalist TAVR was significantly lower than the standard TAVR. The risk of overall death, stroke, and cardiovascular-related readmission within 30 days was similar in both procedures. CONCLUSION Patients with severe aortic stenosis treated with minimalist TAVR have similar short-term efficacy as well as 30-day clinical outcomes to standard TAVR, while minimalist TAVR could reduce the risk of major vascular complications and bleeding complications.

Impact of proficiency in the transcatheter aortic valve implantation procedure on clinical outcomes: a single center retrospective study. BMC Anesthesiol 2024; 24:209. [PMID: 38907200 PMCID: PMC11191309 DOI: 10.1186/s12871-024-02594-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Accepted: 06/10/2024] [Indexed: 06/23/2024] Open
Abstract
BACKGROUND We used transcatheter aortic valve implantation (TAVI) procedure time to investigate the association between surgical team maturity and outcome. METHODS Among patients who underwent TAVI between October 2015 and November 2019, those who had Sapien™ implanted with the transfemoral artery approach were included in the analysis. We used TAVI procedure time and surgery number to draw a learning curve. Then, we divided the patients into two groups before and after the number of cases where the sigmoid curve reaches a plateau. We compared the two groups regarding the surveyed factors and investigated the correlation between the TAVI procedure time and survey factors. RESULTS Ninety-nine of 149 patients were analysed. The sigmoid curve had an inflection point in 23.2 cases and reached a plateau in 43.0 cases. Patients in the Late group had a shorter operating time, less contrast media, less radiation exposure, and less myocardial escape enzymes than the Early group. Surgical procedure time showed the strongest correlation with the surgical case number. CONCLUSION The number of cases required for surgeon proficiency for isolated Sapien™ valve implantation was 43. This number may serve as a guideline for switching the anesthesia management of TAVI from general to local anesthesia.

Abstract
OBJECTIVE A paucity of data exists on how transcatheter aortic valve implantation (TAVI) practice has evolved in Ireland. This study sought to analyse temporal trends in patient demographics, procedural characteristics, and clinical outcomes at an Irish tertiary referral centre. METHODS The prospective Mater TAVI database was divided into time tertiles based on when TAVI was performed: Group A, November 2008-April 2013; Group B, April 2013-September 2017; and Group C, September 2017-February 2022. Patient and procedural characteristics and clinical outcomes were compared across groups. RESULTS A total of 1063 (Group A, 59; Group B, 268; and Group C:, 736) patients were treated with TAVI during the study period (mean age 81.1±7.4, mean Society of Thoracic Surgeons score 5.9±5.1).Conscious sedation (Group A, 0%; Group B, 59.9%; and Group C, 90.2%, p<0.001) and femoral artery access (Group A, 76.3%; Group B, 90.7%; and Group C, 96.6%, p<0.001) were used more frequently over time. The median length of hospital stay reduced from 9 days (IQR 7, 18) in Group A to 2 days (IQR 2, 3) in Group C. In-hospital death was numerically higher in Group A compared with Group C (6.8% vs 1.9%, p=0.078). At 1-year follow-up, the rate of death and/or stroke was similar in Group A and Group C (20.3% vs 12.0%, adjusted HR 1.49, 95% CI (0.59 to 3.74)). CONCLUSION There was exponential growth in TAVI procedural volume during the study period. A minimalist approach to TAVI emerged, and this was associated with significantly shorter procedure duration and hospital stay. Clinical outcomes at 1-year follow-up did not change significantly over time.

General Anesthesia Versus Local Anesthesia in Patients Undergoing Transcatheter Aortic Valve Replacement: An Updated Meta-Analysis and Systematic Review. J Cardiothorac Vasc Anesth 2023; 37:1358-1367. [PMID: 37120319 DOI: 10.1053/j.jvca.2023.03.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 01/07/2023] [Accepted: 03/06/2023] [Indexed: 05/01/2023]
Abstract
OBJECTIVES For patients with aortic stenosis, transcatheter aortic valve replacement (TAVR) offers a less invasive treatment modality than conventional surgical valve replacement. Although the surgery is performed traditionally under general anesthesia (GA), recent studies have described success with TAVR using local anesthesia (LA) and/or conscious sedation. The study authors performed a pairwise meta-analysis to compare the clinical outcomes of TAVR based on operative anesthesia management. DESIGN A random effects pairwise meta-analysis via the Mantel-Haenszel method. SETTING Not applicable, as this is a meta-analysis. PARTICIPANTS No individual patient data were used. INTERVENTIONS Not applicable, as this is a meta-analysis. MEASUREMENTS AND MAIN RESULTS The authors comprehensively searched the PubMed, Embase, and Cochrane databases to identify studies comparing TAVR performed using LA or GA. Outcomes were pooled as risk ratios (RR) or standard mean differences (SMD) and their 95% CIs. The authors' pooled analysis included 14,388 patients from 40 studies (7,754 LA; 6,634 GA). Compared to GA TAVR, LA TAVR was associated with significantly lower rates of 30-day mortality (RR 0.69; p < 0.01) and stroke (RR 0.78; p = 0.02). Additionally, LA TAVR patients had lower rates of 30-day major and/or life-threatening bleeding (RR 0.64; p = 0.01), 30-day major vascular complications (RR 0.76; p = 0.02), and long-term mortality (RR 0.75; p = 0.009). No significant difference was seen between the 2 groups for a 30-day paravalvular leak (RR 0.88, p = 0.12). CONCLUSIONS Transcatheter aortic valve replacement performed using LA is associated with lower rates of adverse clinical outcomes, including 30-day mortality and stroke. No difference was seen between the 2 groups for a 30-day paravalvular leak. These results support the use of minimally invasive forms of TAVR without GA.

Abstract
Purpose of Review This review summarizes current data supporting a minimalist TAVR approach and identifies the need for additional study to optimize TAVR care. The authors discuss future directions of the TAVR landscape and how this necessitates evolution of minimalist care pathways. Recent Findings Transcatheter aortic valve replacement (TAVR) has become a mainstay in the treatment of aortic stenosis since the initial procedure in 2002. Recently, attention has shifted to TAVR optimization and the minimalist approach with a focus on minimizing procedural sedation, protocolization of perioperative management, and prioritization on early discharge. This approach has been shown to be safe and reduce procedure time, length of stay, and overall cost for hospital systems. Summary The minimalist care pathway avoids general anesthesia, shortens procedure time and length of stay, and reduces cost without changing mortality or readmission rates at 30 days. A variety of protocols have been proposed without a clear consensus on specific components or patient eligibility. There is a continued need for data regarding patient risk stratification, valve selection, and discharge strategy as TAVR becomes increasingly common.

Abstract
Background This study is aimed at comparing the clinical outcomes of unprotected left main coronary artery disease (ULMCAD) treatment with contemporary percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in a "real-world" population. Methods and Results Overall, 558 consecutive patients with ULMCAD (mean age 71 ± 9 years, male gender 81%) undergoing PCI or CABG were compared. The primary endpoint was the composite of death, nonfatal myocardial infarction, or stroke. Diabetes was present in 29% and acute coronary syndrome in 56%; mean EuroSCORE was 11 ± 8. High coronary complexity (SYNTAX score >32) was present in 50% of patients. The primary composite endpoint was similar after PCI and CABG up to 4 years (15.5 ± 3.1% vs. 17.1 ± 2.6%; p=0.585). The primary end point was also comparable in a two propensity score matched cohorts. Ischemia-driven revascularization was more frequently needed in PCI than in CABG (5.5% vs. 1.5%; p=0.010). By multivariate analysis, diabetes mellitus (HR 2.00; p=0.003) and EuroSCORE (HR 3.71; p < 0.001) were the only independent predictors associated with long-term outcome. Conclusions In a "real-world" population with ULMCAD, a contemporary revascularization strategy by PCI or CABG showed similar long-term clinical outcome regardless of the coronary complexity.

Abstract
BACKGROUND The change in practice of transcatheter aortic valve replacement (TAVR) to a minimalist approach is a debate. METHODS Online database search for studies that compared the minimalist approach with the standard approach for TAVR were searched from inception through September 2020. We calculated pooled odds ratios (ORs) and 95% confidence intervals (CIs) using the fixed or random-effects model. RESULTS A total of 9 studies with 2,880 TAVR patients (minimalist TAVR;1066 and standard TAVR; 1,814) were included. Compared to standard approach, there were no significant differences in in-hospital mortality, 30-day mortality, or hospital readmissions. However, there was a reduced risk of acute kidney injury (OR0.49;95%CI0.27-0.89), major bleeding (OR0.21;95%CI0.12-0.38) and major vascular complications (OR0.60,95%CI0.39-0.91) associated with the minimalist TAVR group. There was comparatively shorter hospital length of stay (mean difference -2.41;95%CI-2.99,-1.83) days, procedural time (mean difference -43.99;95%CI-67.25,-20.75) minutes, fluoroscopy time (mean difference -2.69;95%CI-3.44,-1.94) minutes and contrast volume (mean difference -26.98;95%CI-42.18,-11.79) ml in the minimalist TAVR group. CONCLUSIONS This meta-analysis demonstrated potential benefits of the minimalist TAVR approach over the standard approach regarding some adverse clinical outcomes as well as procedural outcomes without significant differences in mortality or readmission rates.

Abstract
PURPOSE Several types of structural heart intervention (SHI) use information from multiple imaging modalities to complete an interventional task. For example, in transcatheter aortic valve replacement (TAVR), placement and deployment of a bioprosthetic aortic valve in the aorta is primarily guided by x-ray fluoroscopy (XRF), and echocardiography provides visualization of cardiac anatomy and blood flow. However, simultaneous interpretation of independent x-ray and echo displays remains a challenge for the interventionalist. The purpose of this work was to develop a novel echo/x-ray co-registration solution in which volumetric transthoracic echo (TTE) is transformed to the x-ray coordinate system by tracking the three-dimensional (3D) pose of a probe fiducial attachment from its appearance in two-dimensional (2D) x-ray images. METHODS A fiducial attachment for a commercial TTE probe consisting of rings of high-contrast ball bearings was designed and fabricated. The 3D pose (position and orientation) of the fiducial attachment is estimated from a 2D x-ray image using an algorithm in which a virtual point cloud model of the attachment is iteratively rotated, translated, and forward-projected onto the image until the average sum-of-squares of grayscale values at the projected points is minimized. Fiducial registration error (FRE) and target registration error (TRE) of this approach were evaluated in phantom studies using TAVR-relevant gantry orientations and four standard acoustic windows for the TTE probe. A patient study was conducted to assess the clinical suitability of the fiducial attachment prototype during TTE imaging of patients undergoing SHI. TTE image quality for the task of guiding a transcatheter procedure was evaluated in a reviewer study. RESULTS The 3D FRE ranged from 0.32 ± 0.03 mm (mean ± SD) to 1.31 ± 0.05 mm, depending on C-arm orientation and probe acoustic window. The 3D TRE ranged from 1.06 ± 0.03 mm to 2.42 ± 0.06 mm. Fiducial pose estimation was stable when >75% of the fiducial markers were visible in the x-ray image. A panel of reviewers graded the presentation of heart valves in TTE images from 48 SHI patients. While valve presentation did not differ significantly between acoustic windows (P > 0.05), the mitral valve did achieve a significantly higher image quality compared to the aortic and tricuspid valves (P < 0.001). Overall, reviewers perceived sufficient image quality in 76.5% of images of the mitral valve, 54.9% of images of the aortic valve, and 48.6% of images of the tricuspid valve. CONCLUSIONS Fiducial-based tracking of a commercial TTE probe is compatible with clinical SHI workflows and yields 3D target registration error of less than 2.5 mm for a variety of x-ray gantry geometries and echo probe acoustic windows. Although TTE image quality with respect to target valve anatomy was sufficient for the majority of cases examined, prescreening of patients for sufficient TTE quality would be helpful.
