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.

Differences in circulating blood volume changes during emergence from general anesthesia in transcatheter aortic valve implantation and MitraClip implantation. J Anesth 2024:10.1007/s00540-024-03345-1. [PMID: 38761239 DOI: 10.1007/s00540-024-03345-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 03/31/2024] [Indexed: 05/20/2024]
Abstract
PURPOSE We aimed to compare changes in the circulating blood volume (CBV) during emergence from general anesthesia in patients undergoing transcatheter aortic valve implantation (TAVI) and MitraClip implantation. METHOD We included 97 patients who underwent TAVI or MitraClip implantation. The primary outcome was the rate of change in the estimated CBV associated with emergence from general anesthesia. The secondary outcomes were hemoglobin and hematocrit values before and after emergence from anesthesia for each procedure. Additionally, the independent factors associated with changes in the estimated CBV were assessed using multiple regression analysis. RESULTS In the TAVI group, the hemoglobin concentration increased from 9.6 g/dL before emergence from anesthesia to 10.8 g/dL after emergence (P < 0.001; mean difference, 1.2 g/dL, 95% confidence interval [CI] 1.1-1.3 g/dL). Conversely, no statistically significant change was observed in the hemoglobin concentration before and after emergence from anesthesia in the MitraClip group. The mean rate of change in the estimated CBV was - 15.4% (standard deviation [SD] 6.4%) in the TAVI group and - 2.4% (SD, 4.7%) in the MitraClip group, indicating a significant decrease in the estimated CBV in the former than in the latter (P < 0.001; mean difference, 13.0%; 95% CI 9.9-16.1%). CONCLUSION Emergence from general anesthesia increased the hemoglobin concentration and decreased the estimated CBV in patients undergoing TAVI but did not elicit significant changes in patients undergoing MitraClip implantation. These results may provide a rationale for minimizing blood transfusions during general anesthesia in patients undergoing these procedures.

Abstract
BACKGROUND The comparison between sedation and general anesthesia (GA) in terms of all-cause mortality remains a subject of ongoing debate. The primary objective of our study was to investigate the impact of GA and sedation on all-cause mortality in order to provide clarity on this controversial topic. METHODS A systematic review and meta-analysis were conducted, incorporating cohort studies and RCTs about postoperative all-cause mortality. Comprehensive searches were performed in the PubMed, EMBASE, and Cochrane Library databases, with the search period extending until February 28, 2023. Two independent reviewers extracted the relevant information, including the number of deaths, survivals, and risk effect values at various time points following surgery, and these data were subsequently pooled and analyzed using a random effects model. RESULTS A total of 58 studies were included in the analysis, with a majority focusing on endovascular surgery. The findings of our analysis indicated that, overall, and in most subgroup analyses, sedation exhibited superiority over GA in terms of in-hospital and 30-day mortality. However, no significant difference was observed in subgroup analyses specific to cerebrovascular surgery. About 90-day mortality, the majority of studies centered around cerebrovascular surgery. Although the overall pooled results showed a difference between sedation and GA, no distinction was observed between the pooled ORs and the subgroup analyses based on RCTs and matched cohort studies. For one-year all-cause mortality, all included studies focused on cardiac and macrovascular surgery. No difference was found between the HRs and the results derived from RCTs and matched cohort studies. CONCLUSIONS The results suggested a potential superiority of sedation over GA, particularly in the context of cardiac and macrovascular surgery, mitigating the risk of in-hospital and 30-day death. However, for the longer postoperative periods, this difference remains uncertain. TRIAL REGISTRATION PROSPERO CRD42023399151; registered 24 February 2023.

Abstract
Transcatheter aortic valve implantation (TAVI) is a common practice for severe aortic stenosis, but the choice between general (GA) and local anesthesia (LA) remains uncertain. We conducted a comprehensive literature review until April 2023, comparing the safety and efficacy of LA versus GA in TAVI procedures. Our findings indicate significant advantages of LA, including lower 30-day mortality rates (RR: 0.69; 95% CI [0.58, 0.82]; p < 0.001), shorter in-hospital stays (mean difference: -0.91 days; 95% CI [-1.63, -0.20]; p = 0.01), reduced bleeding/transfusion incidents (RR: 0.64; 95% CI [0.48, 0.85]; p < 0.01), and fewer respiratory complications (RR: 0.56; 95% CI [0.42, 0.76], p<0.01). Other operative outcomes were comparable. Our findings reinforce prior evidence, presenting a compelling case for LA's safety and efficacy. While patient preferences and clinical nuances must be considered, our study propels the discourse towards a more informed anaesthesia approach for TAVI procedures.

Abstract
Background To compare the merits and safety between conscious sedation/monitored anesthesia (CS/MAC) and general anesthesia (GA) for patients receiving transcatheter aortic valve replacement (TAVR). Measurements Databases including EMBASE, MEDLINE, and the Cochrane Library databases were searched from inception to October 2022 to identify studies investigating the impact of CS/MAC on peri-procedural and prognostic outcomes compared to those with GA. The primary outcome was the association of CS/MAC with the risk of 30-day mortality, while secondary outcomes included the risks of adverse peri-procedural (e.g., vasopressor/inotropic support) and post-procedural (e.g., stroke) outcomes. Subgroup analysis was performed based on study design [i.e., cohort vs. matched cohort/randomized controlled trials (RCTs)]. Main results Twenty-four studies (observational studies, n = 22; RCTs, n = 2) involving 141,965 patients were analyzed. Pooled results revealed lower risks of 30-day mortality [odd ratios (OR) = 0.66, p < 0.00001, 139,731 patients, certainty of evidence (COE): low], one-year mortality (OR = 0.72, p = 0.001, 4,827 patients, COE: very low), major bleeding (OR = 0.61, p = 0.01, 6,888 patients, COE: very low), acute kidney injury (OR = 0.71, p = 0.01, 7,155 patients, COE: very low), vasopressor/inotropic support (OR = 0.25, p < 0.00001, 133,438 patients, COE: very low), shorter procedure time (MD = -12.27 minutes, p = 0.0006, 17,694 patients, COE: very low), intensive care unit stay (mean difference(MD) = -7.53 h p = 0.04, 7,589 patients, COE: very low), and hospital stay [MD = -0.84 days, p < 0.00001, 19,019 patients, COE: very low) in patients receiving CS/MAC compared to those undergoing GA without significant differences in procedure success rate, risks of cardiac-vascular complications (e.g., myocardial infarction) and stroke. The pooled conversion rate was 3.1%. Results from matched cohort/RCTs suggested an association of CS/MAC use with a shorter procedural time and hospital stay, and a lower risk of vasopressor/inotropic support. Conclusion Compared with GA, our results demonstrated that the use of CS/MAC may be feasible and safe in patients receiving TAVR. However, more evidence is needed to support our findings because of our inclusion of mostly retrospective studies.

Abstract
It remains controversial to choose anesthesia for transcatheter aortic valve implantation (TAVI). A meta-analysis of cohort studies was conducted to assess the efficacy and safety of local anesthesia (LA) compared to general anesthesia (GA) in TAVI. All relevant studies published from 1 January 2002, to 31 June 2022, were searched in Ovid, PubMed, Embase, Web of Science, and Cochrane Library. A total of 34 studies involving 23,480 patients were included in the meta-analysis. TAVI with LA was associated with a significant reduction in hospital stay [WMD = −2.48, 95% CI (−2.80, −2.16), p < 0.00001], operative [WMD = −12.25, 95% CI (−13.73, −10.78), p < 0.00001] and fluoroscopy time [WMD = −3.30, 95% CI (−5.40, −1.19), p = 0.002], and an increased risk of acute kidney injury [OR = 1.31, 95% CI (1.01, 1.69), p = 0.04] and a reduced incidence of major bleeding [OR = 0.59, 95% CI (0.46, 0.75), p < 0.0001] and the use of cardiovascular drugs [OR = 0.17, 95% CI (0.05, 0.57), p = 0.004]. No differences were found between LA and GA for 30-day mortality, procedural success rate, myocardial infarction, permanent pacemaker implantation, paravalvular leak, shock, and cerebrovascular events. Overall, 4.4% of LA converted to GA. Based on current evidence, our results suggested that LA strategies reduced hospital stay, operative time, fluoroscopy time, cardiovascular drug consumption, and major bleeding rates in patients undergoing TAVI but led to increased acute kidney injury rates. Further studies and randomized trials are required to verify the presented findings and to identify patients who might benefit from LA.

Abstract
Background and Objectives: In patients with severe aortic stenosis (sAS), it is crucial to maintain hemodynamic stability during the induction and maintenance of general anesthesia for transcatheter aortic valve implantation (TAVI). In this study, we assessed the efficacy and safety of remimazolam in maintaining hemodynamic stability during anesthetic induction and maintenance. Cases: TAVI was performed on seven patients with sAS, and remimazolam was administered for total intravenous anesthesia (TIVA) of general anesthesia with induction (3.0 mg/kg/h) and maintenance (1.0 mg/kg/h). All patients underwent TAVI without major hemodynamic concerns and later recovered. Conclusions: Remimazolam can be safely used for induction and maintenance of general anesthesia in patients with sAS when performing TAVI.

Abstract
OBJECTIVES Transcatheter aortic valve replacement (TAVR) has become an alternative treatment for patients with symptomatic aortic stenosis not eligible for surgical valve replacement due to a high periprocedural risk or comorbidities. However, there are several areas of debate concerning the pre-, intra- and post-procedural management. The standards and management for these topics may vary widely among different institutions and countries in Europe. DESIGN Structured web-based, anonymized, voluntary survey. SETTING Distribution of the survey via email among members of the European Association of Cardiothoracic Anaesthesiology working in European centers performing TAVR between September and December 2018. PARTICIPANTS Physicians. MEASUREMENTS AND MAIN RESULTS The survey consisted of 25 questions, including inquiries regarding number of TAVR procedures, technical aspects of TAVR, medical specialities present, preoperative evaluation of TAVR candidates, anesthesia regimen, as well as postoperative management. Seventy members participated in the survey. Reporting members mostly performed 151-to-300 TAVR procedures per year. In 90% of the responses, a cardiologist, cardiac surgeon, cardiothoracic anesthesiologist, and perfusionist always were available. Sixty-six percent of the members had a national curriculum for cardiothoracic anesthesia. Among 60% of responders, the decision for TAVR was made preoperatively by an interdisciplinary heart team with a cardiothoracic anesthesiologist, yet in 5 countries an anesthesiologist was not part of the decision-making. General anesthesia was employed in 40% of the responses, monitored anesthesia care in 44%, local anesthesia in 23%, and in 49% all techniques were offered to the patients. In cases of general anesthesia, endotracheal intubation almost always was performed (91%). It was stated that norepinephrine was the vasopressor of choice (63% of centers). Transesophageal echocardiography guiding, whether performed by an anesthesiologist or cardiologist, was used only ≤30%. Postprocedurally, patients were transferred to an intensive care unit by 51.43% of the respondents with a reported nurse-to-patient ratio of 1:2 or 1:3, to a post-anesthesia care unit by 27.14%, to a postoperative recovery room by 11.43%, and to a peripheral ward by 10%. CONCLUSION The results indicated that requirements and quality indicators (eg, periprocedural anesthetic management, involvement of the anesthesiologist in the heart team, etc) for TAVR procedures as published within the European guideline are largely, yet still not fully implemented in daily routine. In addition, anesthetic TAVR management also is performed heterogeneously throughout Europe.

Abstract
PURPOSE Transcatheter aortic valve implantation (TAVI) has become a widely used technique for treating aortic stenosis. Subclavian access may be warranted in the presence of poor vasculature that precludes femoral access. Conscious sedation is increasingly being adopted with some evidence suggesting better outcomes compared with those of general anesthesia. We describe the use of two regional anesthetic techniques to facilitate subclavian access for TAVI. CLINICAL FEATURES Our case report involves the successful management of a challenging patient with severe peripheral vasculopathy and respiratory compromise undergoing a trans-subclavian TAVI. Surgical anesthesia was provided by low-dose local anesthetic titrated via an interscalene perineural catheter and a single-shot superficial cervical plexus block while preserving respiratory function. CONCLUSIONS The interscalene catheter in situ allowed for low-dose local anesthetic titration without further jeopardizing the pulmonary function throughout the procedure. Unlike other interfascial plane blocks, combined low-dose superficial cervical plexus and interscalene brachial plexus blocks offer surgical anesthesia and limb immobility, thus providing optimal condition for subclavian TAVI to be performed with minimal sedation.

A retrospective study of conscious sedation versus general anaesthesia in patients scheduled for transfemoral aortic valve implantation: A single center experience. Health Sci Rep 2019; 2:e95. [PMID: 30697594 PMCID: PMC6346987 DOI: 10.1002/hsr2.95] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2018] [Revised: 09/04/2018] [Accepted: 09/17/2018] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVES The current 2017 ESC/EACTS guidelines recommend transcatheter aortic valve implantations (TAVIs) as the therapy of choice for inoperable patients with severe symptomatic aortic stenosis. Most of the TAVIs worldwide are performed under general anaesthesia (GA). Although conscious sedation (CS) concepts are increasingly applied in Europe, it is still a matter of debate which concept is associated with highest amount of safety for this high-risk patient population. The aim of this single center, before-and-after study was to investigate feasibility and safety of CS compared with GA with respect to peri-procedural complications and 30-day mortality in patients scheduled for transfemoral TAVI (TF-TAVI). METHODS From March 2012 until September 2014, patients scheduled for the TF-TAVI procedure were included in a prospective, observational manner. From the 200 patients finally included, 107 procedures were performed under GA, using either an endotracheal tube or a laryngeal mask, and balanced anaesthesia. CS was performed in 93 patients using low-dose propofol and remifentanil. RESULTS Conversion to GA was needed 4 times due to procedural-related complications (4.3%), in one patient due to ongoing agitation (1.1%). The CS-group showed significantly shorter key time courses: anaesthesia time (105 [95-120] minutes vs 115 [105-140] minutes, P-value = 0.009, Mann-Whitney-U-test) and length of stay in the intensive care unit (1.6 [1.0-1.5] d vs 2.1 [1.0-2.0] d, P-value = 0.002, Mann-Whitney-U-test). The lowest mean arterial pressure was significantly higher in the CS-group compared with the GA-group (74.3 mmHg vs 55.2 mmHg, P-value <0.0001, t-test). CS was associated with less requirements of norepinephrine (0.1 μg/kg vs 2.3 μg/kg, P-value <0.0001, Mann-Whitney-U-test). CONCLUSIONS Our single-center data demonstrate that CS is a feasible and safe alternative, especially with respect to a higher degree of intra-procedural haemodynamic stability, and a reduced length of stay in the intensive care unit.

Abstract
There is currently significant controversy regarding the best anesthesia management for patients undergoing transcatheter aortic valve replacement (TAVR). Some institutions primarily use general anesthesia (GA) but many institutions primarily use moderate sedation. Much of the controversy is due to the limited evidence base available to inform this decision and the strong feelings and pre-conceived notions about the optimal anesthesia technique which exist amongst anesthesiologists, cardiologists, and cardiac surgeons. In this article and in the context of TAVR, we will define the salient differences between GA and sedation, review the results and limitations of the currently available data, and discuss the priority questions for future research.

Abstract
OBJECTIVES The use of monitored anesthesia care (MAC) for transcatheter aortic valve replacement (TAVR) is gaining favor in the United States, although general anesthesia (GA) continues to be common for these procedures. Open surgical cutdown for transfemoral TAVR has been a relative contraindication for TAVR with MAC at most centers. The objective of this study was to review the authors' results of transfemoral TAVR performed in patients with open surgical cutdown with the use of MAC. DESIGN Retrospective study design from a prospectively recorded database. SETTING Tertiary academic (teaching) hospital. PARTICIPANTS Two hundred eighty-two patients undergoing transfemoral TAVR with open surgical cutdown under MAC from 2015 to 2017. INTERVENTIONS Transfemoral TAVR under MAC with surgical cutdown for femoral vascular access. MEASUREMENTS AND MAIN RESULTS The study cohort consisted of 282 patients with severe aortic stenosis (mean area 0.65 [± 0.16] cm2, mean gradient of 48.9 [±13.3] mmHg, and mean age of 82.7 [± 7.31] years). Eleven (3.9%) patients required conversion to GA. First postoperative pain score (0-10) was 2.9 and highest postoperative pain score was 4.6. Major and minor vascular complications occurred in 2 (0.7%) and 6 (2.1%) patients, respectively. Twenty-nine (10.3%) patients were readmitted within 30 days, and 6 (2.1%) patients had in-hospital mortality. CONCLUSIONS Open surgical cutdown for transfemoral TAVR can be performed safely using MAC and ilioinguinal block with low rates of conversion to general anesthesia and acceptable postoperative outcomes and pain scores.

Abstract
ObjectivePerforming transfemoral transcatheter aortic valve implantation (TAVI) without general anaesthesia (GA) has been increasingly adopted. We sought to study the impact of GA and non-GA approaches on procedural outcome and 30-day and 1-year mortality in transfemoral TAVI.MethodsThe UK TAVI registry holds information for every TAVI procedure in the UK. We analysed the data for patients implanted during 2013–2014 using either an Edwards Sapien or a Medtronic CoreValve prosthesis. Propensity score-matching analysis was performed to adjust for confounding factors.Results2243 patients were studied (aged 81.4±7.5 years, 1195 males). 1816 (81%) underwent TAVI with GA and 427 (19%) without GA. Transoesophageal echocardiography (TOE) was used in 92.3% of GA and 12.4% of non-GA cases (p<0.001). There was no significant difference in the rate of successful valve deployment (GA 97.2% vs non-GA 95.7%, p=0.104) and in the incidence of more than mild aortic regurgitation (AR) at the end of the procedure (GA 5.6% vs non-GA 7.0%, p=0.295). However, procedure time was longer (131±60 vs 121±60mins, p=0.002) and length of stay was greater (8.0±13.5 vs 5.7±5.5 days, p<0.001) for GA cases. 30-day and 1-year mortality rates did not differ between the GA and non-GA cases. After propensity matching, these results remained unchanged. A second propensity analysis (adjusted for mode of anaesthesia) did not show an association between use of TOE and rate of successful valve deployment or frequency of significant AR. Neither was TOE associated with a longer procedural time or greater length of stay.ConclusionProcedure outcome, and 30-day and 1-year mortality are not influenced by mode of anaesthesia. However, GA is associated with longer procedure duration and greater length of stay.

Abstract
OBJECTIVES The importance of thrombocytopenia (TP) has been discussed previously. However, data are still limited, especially on predictors of TP. We sought to investigate predictors of TP after transcatheter aortic valve replacement (TAVR), in particular, clinically significant TP. METHODS We reviewed a total of 123 consecutive patients undergoing TAVR in our medical center. They were stratified into 3 groups according to the nadir platelet count post-TAVR: no/mild TP, moderate TP, and severe TP. Clinically significant TP, also known as major TP, was defined as moderate-to-severe TP (a nadir platelet count <100 × 109/L and a >50% decrease in platelet count). RESULTS Baseline platelet, baseline hemoglobin, general anesthesia (GA), valve malpositioning and post-TAVR left ventricular ejection fraction were found to be predictors of post-TAVR nadir platelet count. Major TP was associated with a higher risk of major bleeding (OR 3.524, 95% CI 1.546-8.031) and 1-month mortality (OR 11.226, 95% CI 1.208-104.328). Age (OR 1.110, 95% CI 1.014-1.215) and GA (OR 6.494, 95% CI 2.058-20.408) were predictors of major TP. CONCLUSION Post-TAVR nadir platelet count can be predicted based on baseline and procedural data. Old age and GA contribute to clinically significant TP.

Abstract
OBJECTIVES We conducted a systematic review and meta-analysis to identify the potential favourable effects of local anaesthesia plus sedation (LAS) compared with general anaesthesia (GA) in transcatheter aortic valve implantation (TAVI). METHODS Electronic databases (PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials) and the reference lists of eligible publications were screened for randomised controlled trials (RCTs) and observational studies published between 1 January 2006 and 26 June 2016 that compare LAS to GA in an adult study population undergoing TAVI. We conducted study quality assessments using the Cochrane risk of bias tool and structured the review according to PRISMA. A meta-analysis calculating the pooled risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs) under the assumption of a random-effects model was performed. Statistical heterogeneity was evaluated using the I² statistic and Cochran's Q-test. RESULTS After database screening, one RCT and 19 observational studies were included in the review. We found no differences between LAS and GA in terms of 30-day mortality, in-hospital mortality and other endpoints that addressed safety and complication rates. LAS was associated with a shorter ICU and hospital stay and with lower rates of catecholamine administration and red blood cell transfusion. New pacemaker implantations occurred more frequently under LAS. The overall conversion rate from LAS to GA was 6.2%. CONCLUSION For TAVI, both LAS and GA are feasible and safe. LAS may have some benefits such as increased haemodynamic stability and shorter hospital and ICU stays, but it does not impact 30-day mortality. Since there is a paucity of randomised trial data and the findings are mainly based on observational study data, this review should be considered as a hypothesis-generating article for subsequent RCTs that are required to confirm the potential favourable effects we detected for LAS.

Abstract
OBJECTIVE Transcatheter aortic valve implantation (TAVI) is a minimally invasive therapy for elderly patients with severe aortic valve stenosis who were refused surgical aortic valve replacement because of the high perioperative risk. Traditionally, this procedure has been done under general anesthesia, but more recently local anesthesia and sedation have become popular. This research assessed the effectiveness of transfemoral TAVI under bispectral index (BIS)-guided sedation. METHODS In this single-center retrospective control analysis, clinical data, including demographic characteristics, echocardiography, periprocedural data, and main complications, were collected and assessed in 113 patients undergoing TAVI through the femoral artery under general anesthesia (GA group, n=36) and under BIS-guided sedation (SED group, n=77). RESULTS The demographic characteristics and echocardiographic parameters between the two groups were similar (P>0.05). Two (2.6%) of patients were moved from BIS-guided sedation to general anesthesia for surgical reasons. Procedures were significantly shorter in the SED group than in the GA group ((127.10±44.43) min vs. (165.90±71.62) min, P=0.004). Patients in the SED group lost less blood and received significantly fewer red blood cells and catecholamines than those in the GA group (5.19% vs. 22.22%, P=0.017 and 67.53% vs. 97.22%, P<0.001). The length of hospital stay was significantly shorter and there were fewer pulmonary complications in the SED group than in the GA group. Thirty-day mortality was similar between the two groups. CONCLUSIONS BIS-guided sedation is a feasible and safe approach for transfemoral TAVI. The anesthesiologist should choose the best anesthetic method according to the team's experience.

Improved costs and outcomes with conscious sedation vs general anesthesia in TAVR patients: Time to wake up? PLoS One 2017; 12:e0173777.

Abstract
Background Transcatheter aortic valve replacement (TAVR) has become a commonplace procedure for the treatment of aortic stenosis in higher risk surgical patients. With the high cost and steadily increasing number of patients receiving TAVR, emphasis has been placed on optimizing outcomes as well as resource utilization. Recently, studies have demonstrated the feasibility of conscious sedation in lieu of general anesthesia for TAVR. This study aimed to investigate the clinical as well as cost outcomes associated with conscious sedation in comparison to general anesthesia in TAVR. Methods Records for all adult patients undergoing TAVR at our institution between August 2012 and June 2016 were included using our institutional Society of Thoracic Surgeons (STS) and American College of Cardiology (ACC) registries. Cost data was gathered using the BIOME database. Patients were stratified into two groups according to whether they received general anesthesia (GA) or conscious sedation (CS) during the procedure. No-replacement propensity score matching was done using the validated STS predicted risk of mortality (PROM) as a propensity score. Primary outcome measure with survival to discharge and several secondary outcome measures were also included in analysis. According to our institution's data reporting guidelines, all cost data is presented as a percentage of the general anesthesia control group cost. Results Of the 231 patients initially identified, 225 (157 GA, 68 CS) were included for analysis. After no-replacement propensity score matching, 196 patients (147 GA, 49 CS) remained. Overall mortality was 1.5% in the matched population with a trend towards lower mortality in the CS group. Conscious sedation was associated with significantly fewer ICU hours (30 vs 96 hours, p = <0.001) and total hospital days (4.9 vs 10.4, p<0.001). Additionally, there was a 28% decrease in direct cost (p<0.001) as well as significant decreases in all individual all cost categories associated with the use of conscious sedation. There was no difference in composite major adverse events between groups. These trends remained on all subsequent subgroup analyses. Conclusion Conscious sedation is emerging as a safe and viable option for anesthesia in patients undergoing transcatheter aortic valve replacement. The use of conscious sedation was not only associated with similar rates of adverse events, but also shortened ICU and overall hospital stays. Finally, there were significant decreases in all cost categories when compared to a propensity matched cohort receiving general anesthesia.

Abstract
Transcatheter aortic valve implantation (TAVI) is an alternative, less invasive method to use for aortic valve replacement in high-risk patients. This operation allows a faster recovery, reduced tissue damage, less postoperative pain, increased patient satisfaction, reduced intensive care unit (ICU) stay, avoidance of ICU admission, reduced hospital stay, and reduced wound infection rates. A retrograde transfemoral approach is commonly used in TAVI procedures. The role of the anaesthetist is important for a successful outcome. General or local anaesthesia, with or without conscious sedation, may be used according to patient characteristics, the presence of comorbidities, and the preference of the surgical team. There is no general consensus regarding which patients should receive general or local anaesthesia during TAVI operations; therefore, the surgical team’s preference has an important influence on the selection of anaesthetic technique. There are many studies in the literature relating to the anaesthesia technique used in TAVI operations. No matter which technique is used, anaesthetists should provide and maintain optimal haemodynamic stability during the procedure. On the other hand, anaesthetists should be cautious of possible procedural complications, such as hypotension, ventricular fibrillation, permanent pacemaker requirement, and emergency aortic valve replacement requirement.

Abstract
BACKGROUND Percutaneous valve therapies represent one of the most innovative areas within interventional cardiology in the past 10 years. AIM The aim of this work is to give an overview of current and upcoming therapeutic options. MATERIALS AND METHODS In this manuscript, the results of a retro- and prospective literature research are summarized. RESULTS AND DISCUSSION With the introduction of percutaneous therapies for valvular heart disease, patients who were previously considered too ill for surgery can now be treated. The percutaneous treatment of aortic or mitral valve disease has become standard therapy. Likewise, promising results have been obtained for percutaneous treatment options for pathologies of the tricuspid valve, which are still under intense investigation.
