Abstract
OBJECTIVE Transcatheter aortic valve replacement (TAVR) has arisen as a viable alternative to surgery. Similarly, minimally invasive surgical aortic valve replacement (mini-SAVR), such as ministernotomy and minithoracotomy, have also gained interest. We conducted a pairwise meta-analysis to further investigate the efficacy of TAVR versus mini-SAVR. METHODS Medical databases were comprehensively searched for studies comparing TAVR with a mini-SAVR modality, defined as minimally invasive aortic surgery, ministernotomy, minithoracotomy, or rapid-deployment or sutureless SAVR. Random-effects meta-analysis was conducted using the generic inverse variance method. Primary outcomes included 30-day mortality, midterm mortality, 30-day stroke, acute kidney injury (AKI), paravalvular leak (PVL), new permanent pacemaker (PPM), new-onset atrial fibrillation, and postintervention mean and peak valve pressure gradients and were pooled as risk ratio (RR), mean difference (MD), or hazard ratio (HR) with 95% confidence interval (CI). RESULTS A total of 5,071 patients (2,505 mini-SAVR vs 2,566 TAVR) from 12 studies were pooled. Compared with TAVR, mini-SAVR showed significantly lower rates of both 30-day (RR = 0.63, 95% CI: 0.42 to 0.96, P = 0.03) and midterm mortality at 4 years of follow-up (HR = 0.76, 95% CI: 0.67 to 0.87, P < 0.001). Furthermore, mini-SAVR was protective against 30-day PVL (RR = 0.07, 95% CI: 0.04 to 0.13, P < 0.001) and new PPM (RR = 0.25, 95% CI: 0.11 to 0.57, P < 0.001). Conversely, TAVR was protective against 30-day AKI (RR = 1.67, 95% CI: 1.20 to 2.32, P = 0.002) and postinterventional mean gradients (MD = 1.65, 95% CI: 0.25 to 3.05, P = 0.02). No difference was observed for 30-day stroke (RR = 0.84, 95% CI: 0.56 to 1.24, P = 0.38), new-onset atrial fibrillation (RR = 1.79, 95% CI: 0.93 to 3.44, P = 0.08), or postinterventional peak gradients (MD = 3.24, 95% CI: -1.10 to 7.59, P = 0.14). CONCLUSIONS Compared with TAVR, mini-SAVR was protective against 30-day and midterm mortality, 30-day PVL, and new permanent pacemaker, while TAVR patients had lower 30-day AKI. Future randomized trials comparing the efficacy of mini-SAVR approaches with TAVR are needed.

Management of aortic stenosis: a systematic review of clinical practice guidelines and recommendations. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2021; 7:340-353. [PMID: 33751049 DOI: 10.1093/ehjqcco/qcab016] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/12/2020] [Revised: 02/27/2021] [Accepted: 03/03/2021] [Indexed: 02/06/2023]
Abstract
Multiple guidelines exist for the management of aortic stenosis (AS). We systematically reviewed current guidelines and recommendations, developed by national or international medical organizations, on management of AS to aid clinical decision-making. Publications in MEDLINE and EMBASE between 1 June 2010 and 15 January 2021 were identified. Additionally, the International Guideline Library, National Guideline Clearinghouse, National Library for Health Guidelines Finder, Canadian Medical Association Clinical Practice Guidelines Infobase, and websites of relevant organizations were searched. Two reviewers independently screened titles and abstracts. Two reviewers assessed rigour of guideline development and extracted the recommendations. Of the seven guidelines and recommendations retrieved, five showed considerable rigour of development. Those rigourously developed, agreed on the definition of severe AS and diverse haemodynamic phenotypes, indications and contraindications for intervention in symptomatic severe AS, surveillance intervals in asymptomatic severe AS, and the importance of multidisciplinary teams (MDTs) and shared decision-making. Discrepancies exist in age and surgical risk cut-offs for recommending surgical aortic valve replacement (SAVR) vs. transcatheter aortic valve implantation (TAVI), the use of biomarkers and complementary multimodality imaging for decision-making in asymptomatic patients and surveillance intervals for non-severe AS. Contemporary guidelines for AS management agree on the importance of MDT involvement and shared decision-making for individualized treatment and unanimously indicate valve replacement in severe, symptomatic AS. Discrepancies exist in thresholds for age and procedural risk used in choosing between SAVR and TAVI, role of biomarkers and complementary imaging modalities to define AS severity and risk of progression in asymptomatic patients.

Abstract
Minimally invasive cardiac surgery options, which originated with off-pump coronary artery bypass grafting and aortic valve procedures, continue to evolve in order to address complex conditions, including those requiring mitral and tricuspid valve repair. Although these procedures are primarily indicated for high-risk patient populations, favorable patient outcomes have resulted in recommendations being expanded to include intermediate-risk groups. This article increases nursing-related knowledge of minimally invasive cardiac procedures, providing an overview of current minimally invasive cardiac surgeries and their associated risks and benefits.

Abstract
INTRODUCTION Cor-Knot automated fastener has been used as an adjunct in heart valve surgery to eliminate the need for manual tying during valve implantation. Although reduced operative time and facilitation for minimally invasive surgery are clear benefits, whether their use translates to improved patient outcome remains debatable. This study aims to review the safety and efficacy of automated fasteners in heart valve surgeries. METHOD Specific searches were conducted via online medical databases (Pubmed, Embase, Ovid) between 1950 and June 2019. Longitudinal studies were included that provided operative parameters. RESULTS The initial literature search identified 3773 articles, but only eight met the inclusion criteria and were used for analysis: four studies related to aortic valve replacement (AVR), four related to mitral valve (MV) intervention (total n = 810). The meta-analysis revealed the significantly shorter aortic cross-clamp time in the Cor-knot group compared to manual tying, both in AVR and MV surgeries (P < .05). Cardiopulmonary bypass time was significantly shorter in the Cor-knot group when analyzing studies in MV surgery (weighted mean difference [WMD]: 110.0; 95% confidence interval: 12.3-207.7; P = .027) The use of Cor-Knot did not increase the risk of permanent pacemaker implantation, paravalvular leak, and 30-day mortality. The majority of studies reported no change in the length of intensive unit care and total hospital stay. CONCLUSION We confirmed that the majority of existing literatures indicated the safety and intraoperative efficacy with automated fastener application. Nevertheless, there is currently no evidence to support automated fastened sutures can translate its intraoperative advantages to improved patient outcome.

Abstract
Objectives Limited aortic annulus exposure during minimal invasive aortic valve replacement (mini-AVR) proves to be challenging and contributes to procedure complexity, resulting in longer procedure times. New innovations like sutureless valves have been introduced to reduce procedure complexity. Additionally, preoperative imaging could also contribute to reducing procedure times. Therefore, we hypothesize that Computed Tomography (CT)-image based measurements are associated with mini-AVR complexity. Methods One hundred patients who underwent a mini-sternotomy and had a preoperative CT scan were included. With a CT-based mini-AVR planning tool, we measured access distance, access angle, annulus dimensions, and calcium volume. The associations of these measurements with cardiopulmonary bypass (CPB) time and aortic cross-clamp (AoX) time were assessed using univariable and multivariable regression models. In the multivariable models, these measurements were adjusted for age and suture technique. Results In the univariable regression models, calcium volume and annulus dimensions were associated with longer CPB and AoX time. After adjusting for age and suture technique, increasing calcium volume was still associated with longer CPB (adjusted β-coefficient 0.002, 95%-CI (0.005, 0.019), p-value = 0.002) and AoX time (adjusted β-coefficient 0.010, 95%-CI (0.004, 0.016), p-value = 0.002). However, after adjusting for these confounders, the association between annulus dimensions and procedure times lost statistical significance. Conclusion Increase in calcium volume are associated with longer CPB and AoX times, with age and sutureless valve implantation as independent confounders. In contrast to previous studies, access angle was not associated with procedure complexity.

Abstract
OBJECTIVES Aortic valve disease is prevalent in the veteran population. Transcatheter aortic valve replacement (TAVR) and minimally invasive surgical aortic valve replacement (MIAVR) are minimally invasive approaches predominantly performed at higher-volume cardiac centers. The study aim was to evaluate our experience with minimally invasive techniques at a Veterans Affairs Medical Center (VAMC), since outcomes from lower-volume federal facilities are relatively unknown. METHODS This study examined retrospective data from 228 consecutive patients who underwent treatment for isolated aortic valve disease with MIAVR or TAVR via intent-to-treat at a VAMC between January 2011 and July 2017. Perioperative outcomes were analyzed using Stata version 15. RESULTS Operative mortality was 1.1% for MIAVR and 0.7% for TAVR (Χ² P=.79). Median length of hospital stay was 10 days (interquartile range [IQR], 7-14 days) for MIAVR and 4 days for TAVR (IQR, 3-6 days; Mann-Whitney P<.001). Postoperative new-onset atrial fibrillation occurred in 52% of MIAVR patients and 5.2% of TAVR patients (Χ² P<.001). Stroke occurred in 2.2% of MIAVR patients and 3.0% of TAVR patients (Χ² P=.71). In patients who underwent MIAVR, 5.4% required placement of a permanent pacemaker postoperatively, compared with 14% of TAVR patients (Χ² P=.04). Mild paravalvular leak (PVL) affected 2.2% of MIAVR and 28% of TAVR patients, with moderate PVL reported in 2.2% of MIAVR and 3% of TAVR patients (Χ² P<.001). CONCLUSIONS The VAMC heart team offers MIAVR and TAVR to veterans with isolated aortic valve disease, and has achieved excellent outcomes despite relatively lower case volumes. Both offer excellent hemodynamic results, with low mortality in a complex population.
