Abstract
The purpose of this first-in-human (FIH) study was to determine the safety and feasibility of the transfemoral premounted dry-pericardium Vienna Self-Expandable Supra-Annular Aortic Valve System. This novel system is repositionable and retrievable and comes already premounted on the delivery system, eliminating the need for assembly and crimping of the device before valve implantation. This is a prospective, nonrandomized, single-arm, single-center, first-stage FIH feasibility study, which will be followed by a second-stage pivotal, multicenter, multinational study in symptomatic patients with severe aortic stenosis. The first-stage FIH study evaluated the safety and feasibility of the device in 10 patients with severe aortic stenosis based on recommendations by the Valve Academic Research Consortium-2 for transcatheter aortic valve implantations. The mean patient age was 79 ± 5 years, 60% were male, and all patients were in New York Heart Association functional class II to III. The primary safety end point was successful when all patients were alive at 30-day follow-up. Device and technical success were observed in all patients. Two patients had a stroke, 1 of which occurred 5 days after the procedure. New permanent pacemakers were implanted in 2 patients (22.2%), of which only 1 was because of complete heart block. Only 1 patient (10%) had moderate paravalvular leak at 30 days. After the procedure, the mean aortic valve gradient decreased from 48.7 ± 10.8 mm Hg to 8.8 ± 4.3 mm Hg. In conclusion, this FIH feasibility study demonstrates successful procedural feasibility, with no 30-day mortality and favorable valve hemodynamic performance, leading to an improvement in quality of life. ClinicalTrials.gov identifier NCT04861805.

Abstract
OBJECTIVE Monitored anesthesia care (MAC) has been increasingly used in lieu of general anesthesia (GA) for transcatheter aortic valve replacement (TAVR). We sought to compare outcomes and in-hospital costs between MAC and GA for TAVR at a Veterans Affairs Medical Center. METHODS A single-center retrospective review was performed of 349 patients who underwent transfemoral TAVR (MAC, n = 244 vs GA, n = 105) from January 2014 to December 2019. Baseline patient characteristics, operating room (OR) time, intensive care unit (ICU) length of stay (LOS), and cost, total LOS, hospital cost, total cost, and complication rates were collected. Propensity matching was performed and resulted in 83 matched pairs. RESULTS In the unmatched TAVR cohort, MAC TAVR was associated with reduced OR time (146 vs 198 min, P < 0.001), ICU LOS (1.4 vs 1.8 days, P < 0.001), total hospital LOS (3.4 vs 5.4 days, P < 0.001), and lower index total cost ($81,300 vs $85,400, P = 0.010). After propensity matching, MAC TAVR patients had reduced OR time (146 vs 196 min, P < 0.05), ICU LOS (1.2 vs 1.7 days, P = 0.006), total LOS (3.5 vs 5.1 days, P = 0.001), and 180-day mortality (2.4% vs 12%, P < 0.03). There was no difference in total hospitalization cost or total cost. CONCLUSIONS In propensity-matched groups, TAVR utilizing MAC is associated with improved OR time efficiency, decreased LOS, and a reduction in 180-day mortality but no significant difference in cost.

Abstract
Computational Fluid Dynamics (CFD) is used to assist in designing artificial valves and planning procedures, focusing on local flow features. However, assessing the impact on overall cardiovascular function or predicting longer-term outcomes may requires more comprehensive whole heart CFD models. Fitting such models to patient data requires numerous computationally expensive simulations, and depends on specific clinical measurements to constrain model parameters, hampering clinical adoption. Surrogate models can help to accelerate the fitting process while accounting for the added uncertainty. We create a validated patient-specific four-chamber heart CFD model based on the Navier-Stokes-Brinkman (NSB) equations and test Gaussian Process Emulators (GPEs) as a surrogate model for performing a variance-based global sensitivity analysis (GSA). GSA identified preload as the dominant driver of flow in both the right and left side of the heart, respectively. Left-right differences were seen in terms of vascular outflow resistances, with pulmonary artery resistance having a much larger impact on flow than aortic resistance. Our results suggest that GPEs can be used to identify parameters in personalized whole heart CFD models, and highlight the importance of accurate preload measurements.

Abstract
Aortic stenosis has a high mortality rate in patients who do not receive aortic valve replacement. Previously, transcatheter aortic valve replacement (TAVR) was an intervention reserved for individuals deemed high-risk for surgery. Since that time, TAVR has increasingly been offered to lower risk patients, yet it is unclear whether TAVR will meet an acceptable cost-effectiveness threshold in this group. In this cost-effectiveness study, we employed a decision tree model with Monte Carlo probability sensitivity analysis to determine the incremental cost (in US$) per quality-adjusted life year (QALY) and life year (LY) of performing the TAVR procedure using the resource-intensive approach versus the minimally invasive strategy in high-risk surgical patients.

Abstract
BACKGROUND Systemic inflammation has been identified as a major cardiovascular risk factor in patients undergoing transcatheter aortic valve replacement (TAVR), yet currently, it is not adequately portrayed in scores for pre-interventional risk assessment. The aim of this study was to investigate the predictive ability of TNF-α in TAVR. METHODS A total of 431 patients undergoing transfemoral TAVR were enrolled in this study. Blood samples were drawn prior to intervention, 24 h post-intervention, 4, 5, and 7 days post-intervention, and 1, 3, and 6 months post-TAVR. RESULTS In a univariate Cox proportional hazard analysis, plasma concentrations of TNF-α after 24 h and after 5 days were associated with mortality after 12 months (after 24 h: HR 1.002 (1.000-1.004), p = 0.028; after 5d: HR 1.003 (1.001-1.005), p = 0.013). This association remained significant even after correction for confounders in a multivariate Cox regression analysis. Additionally, cut-offs were calculated. Patients above the cut-off for TNF-α after 5d had a significantly worse 12-month mortality than patients below the cut-off (18.8% vs. 2.8%, p = 0.046). CONCLUSION Plasma levels of TNF-α after 24 h and 5 days were independently associated with 12-month mortality in patients undergoing TAVR. Thus, TNF-α could represent a novel biomarker for enhanced risk stratification in these patients.

Abstract
Objective We sought to investigate real-world outcomes of patients with degenerated biological aortic valve prostheses who had undergone valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) or reoperative surgical aortic valve replacement (redo-SAVR) in the Netherlands. Methods Patients who had undergone ViV-TAVI or redo-SAVR for a degenerated biological aortic valve prosthesis in the Netherlands between January 2014 and December 2018 were eligible for this retrospective study. Patients with a prior homograft, active endocarditis or mechanical aortic valve prosthesis were excluded. Patients were matched using the propensity score. The primary endpoint was a composite of 30-day all-cause mortality and in-hospital postoperative stroke. Secondary endpoints were all-cause mortality at different time points, in-hospital postoperative stroke, pacemaker implantation and redo procedures within one year. Baseline characteristics and outcome data were collected from the Netherlands Heart Registration. Results From 16 cardiac centres, 653 patients were included in the study (374 ViV-TAVI and 279 redo-SAVR). European System for Cardiac Operative Risk Evaluation I (EuroSCORE I) was higher in ViV-TAVI patients (19.4, interquartile range (IQR) 13.3–27.9 vs 13.8, IQR 8.3–21.9, p < 0.01). After propensity score matching, 165 patients were matched with acceptable covariate balance. In the matched cohorts, the primary endpoint was not significantly different for ViV-TAVI and redo-SAVR patients (odds ratio 1.30, 95% confidence interval 0.57–3.02). Procedural, 30-day and 1‑year all-cause mortality rates, incidence of in-hospital postoperative stroke, pacemaker implantation and redo procedures within one year were also similar between cohorts. Conclusion Patients with degenerated aortic bioprostheses treated with ViV-TAVI or redo-SAVR have similar mortality and morbidity.

Abstract
Background The aim of this study was to evaluate the safety and efficacy of transcatheter aortic valve implantation (TAVI) program in a Tertiary care hospital in Karachi, Pakistan. Methodology This study was conducted by interventional cardiology department of the National Institute of Cardiovascular Diseases (NICVD), Karachi from July 2015 to February 2020. All patients of severe aortic stenosis (AS) who underwent TAVI were included. Baseline characteristics, in-hospital course and one-month follow-up data were collected. Results This study included 100 consecutive patients with severe AS undergoing TAVI. Sixty-three (63.0%) patients were males and the mean age was 67.38 ± 10.73 years. Eighty-five (85%) patients were in the New York Heart Association (NYHA) class III-IV. Aortic valve mean gradient was 51.33±10.47 mmHg and 50% of patients had bicuspid aortic valves. Core valve was implanted in 86 (86%) and evolute-R aortic valve was implanted in 14 (14%) patients. TAVI was successfully done in 94% of patients. Post-deployment aortic valve mean gradient was 5.33±4.13 mmHg. Major vascular access site complications were noted in 14% and atrioventricular (AV) blocks were seen in 22% of cases. There was a significant difference in symptoms of patients before and after the procedure. Overall, eight (8%) patients expired during hospital stay. At one-month follow-up, 76% of patients were found to have no limitation of physical activities. Conclusions Results of this study showed that TAVI is a safe procedure in these high-risk patients and is an alternative to surgery for AS patients in the region.

Abstract
Cardiovascular diseases are still among the first causes of death worldwide with a huge impact on healthcare systems. Within these conditions, the correct diagnosis of coronary artery disease with the most appropriate imaging-based evaluations is of utmost importance. The sustainability of the healthcare systems, considering the high economic burden of modern cardiac imaging equipments, makes cost-effective analysis an important tool, currently used for weighing different costs and health outcomes, when policy makers have to allocate funds and to prioritize interventions, getting the most out of their financial resources. This review aims at evaluating cost-effective analysis in the more recent literature, focused on the role of Calcium Score, coronary computed tomography angiography and cardiac magnetic resonance.

Abstract
PURPOSE OF REVIEW Highlight the difficulties patients, physicians, and the global economy face in relation to treatment of structural heart diseases. It is easy to be carried away by the excitement of medical advancement; however, it is difficult to demonstrate restraint. Transcatheter aortic valve replacement (TAVR) is a modern marvel that can help many patients when utilized appropriately. This article highlights the work that has been done to facilitate decision-making in this challenging patient population. RECENT FINDINGS Patient selection is of paramount importance as TAVR remains a costly intervention. Currently, our gold standards for preprocedural patient evaluation are inadequate. Apropos, several objective tools are being developed to help clinicians evaluate frailty. Giving patients a more accurate postprocedure prognosis allows them to make informed decisions on whether this intervention is appropriate for their respective goals. SUMMARY In order for us to fully embrace shared decision-making and cost-effectiveness, we must continue to work on our prognostic tools and have honest conversations with patients and their families to formulate individualized treatment plans. This becomes even more important when factors like economic impact of intervention are considered. In an era where cost-effective care has garnered more attention than ever before, we must do our best to make sure our interventions are in line with patient goals and offer the maximum amount of benefit, given the current cost of TAVR.

Abstract
Transcatheter aortic valve implantation (TAVI) has emerged as one of the most popularly deployed interventional innovations of recent times. After addressing the inoperable and high-risk patients, it is application is being extended to intermediate and low-risk category. There is some disquiet about the strength of evidence on which the clinical application is based. Durability and pacemaker requirement are also areas of concern. This review highlights the areas of concern on these aspects. There is also a need to address these deficiencies in future trials and also bring updated database reports in the public domain.

Abstract
A growing number of nonagenarians is recorded as life expectancy increases. Unfortunately, this extreme-aged group is plagued by increased prevalence of aortic stenosis amidst a higher occurrence of comorbidities that pose dilemmas to cardiologists and cardiac surgeons when having to choose a conservative or interventional treatment modality, and a surgical or transcatheter aortic valve implantation (TAVI) approach. TAVI is an expensive procedure, which also confers a higher mortality and morbidity risk in nonagenarians, compared to younger patients. Considering the physiologic rather the chronologic age alone, and adopting a shared-decision making approach (participatory medicine), it may be more realistic to determine a patient's candidacy for this non-surgical therapeutic modality. Thus, it comes down to the patient selection process by having the heart team review each nonagenarian case individually and getting the patient and the family involved, always aiming to prolong and improve patient's quality of life (QoL), but also taking into consideration patient preferences and values, sharing and respecting goals, realistic expectations, and end-of-life views and ideas. One should keep in mind that there is always the possibility that TAVI may be clinically futile for patients who have a multitude of comorbidities and extreme frailty, for whom a transition to palliative care might be prudent. Selecting nonagenarian patients with low comorbidity index and with no extreme frailty, adopting a minimalistic approach and paying attention to vascular access hemostasis may provide the elements that may lead to a successful, desirable and hopefully cost-effective outcome.
