Abstract
BACKGROUND Data on valve reintervention after transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) are limited. OBJECTIVES The authors compared the 5-year incidence of valve reintervention after self-expanding CoreValve/Evolut TAVR vs SAVR. METHODS Pooled data from CoreValve and Evolut R/PRO (Medtronic) randomized trials and single-arm studies encompassed 5,925 TAVR (4,478 CoreValve and 1,447 Evolut R/PRO) and 1,832 SAVR patients. Reinterventions were categorized by indication, timing, and treatment. The cumulative incidence of reintervention was compared between TAVR vs SAVR, Evolut vs CoreValve, and Evolut vs SAVR. RESULTS There were 99 reinterventions (80 TAVR and 19 SAVR). The cumulative incidence of reintervention through 5 years was higher with TAVR vs SAVR (2.2% vs 1.5%; P = 0.017), with differences observed early (≤1 year; adjusted subdistribution HR: 3.50; 95% CI: 1.53-8.02) but not from >1 to 5 years (adjusted subdistribution HR: 1.05; 95% CI: 0.48-2.28). The most common reason for reintervention was paravalvular regurgitation after TAVR and endocarditis after SAVR. Evolut had a significantly lower incidence of reintervention than CoreValve (0.9% vs 1.6%; P = 0.006) at 5 years with differences observed early (adjusted subdistribution HR: 0.30; 95% CI: 0.12-0.73) but not from >1 to 5 years (adjusted subdistribution HR: 0.61; 95% CI: 0.21-1.74). The 5-year incidence of reintervention was similar for Evolut vs SAVR (0.9% vs 1.5%; P = 0.41). CONCLUSIONS A low incidence of reintervention was observed for CoreValve/Evolut R/PRO and SAVR through 5 years. Reintervention occurred most often at ≤1 year for TAVR and >1 year for SAVR. Most early reinterventions were with the first-generation CoreValve and managed percutaneously. Reinterventions were more common following CoreValve TAVR compared with Evolut TAVR or SAVR.

Abstract
BACKGROUND Adequate valve performance after surgical mitral valve repair with an annuloplasty ring is not always sustained over time. The risk of repeat mitral valve surgery may be high in these patients. Transcatheter mitral valve-in-ring (MViR) is emerging as an alternative for high-risk patients. OBJECTIVES The authors sought to assess contemporary outcomes of MViR using third-generation balloon-expandable aortic transcatheter heart valves. METHODS Patients who underwent MViR and were enrolled in the STDS/ACC TVT (Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy) Registry between August 2015 and December 2022 were analyzed. RESULTS A total of 820 patients underwent MViR at 236 sites, mean age was 72.2 ± 10.4 years, 50.9% were female, mean STS score was 8.2% ± 6.9%, and most (78%) were in NYHA functional class III to IV. Mean left ventricular ejection fraction was 47.8% ± 14.2%, mean mitral gradient was 8.9 ± 7.0 mm Hg, and 75.5% had ≥ moderate mitral regurgitation. Access was transseptal in 93.9% with 88% technical success. All-cause mortality at 30 days was 8.3%, and at 1 year, 22.4%, with a reintervention rate of 9.1%. At 1-year follow-up, 75.6% were NYHA functional class I to II, Kansas City Cardiomyopathy Questionnaire score increased by 25.9 ± 29.1 points, mean mitral valve gradient was 8.4 ± 3.4 mm Hg, and 91.7% had ≤ mild mitral regurgitation. CONCLUSIONS MViR with third-generation balloon-expandable aortic transcatheter heart valves is associated with a significant reduction in mitral regurgitation and improvement in symptoms at 1 year, but with elevated valvular gradients and a high reintervention rate. MViR is a reasonable alternative for high-risk patients unable undergo surgery who have appropriate anatomy for the procedure. (STS/ACC TVT Registry Mitral Module [TMVR]; NCT02245763).

Abstract
BACKGROUND The next generation supra-annular, self-expanding Evolut FX transcatheter aortic valve (TAV) system was designed to improve catheter deliverability, provide stable and symmetric valve deployment, and assess commissural alignment during the procedure. The impact of these modifications has not been clinically evaluated. METHODS Procedural information was collected by survey in 2 Stages: Stage I comprised 23 centers with extensive experience with Evolut TAV systems, and Stage II comprised an additional 46 centers with a broad range of balloon- and self-expanding system experience. Operators were to compare the experience with the Evolut FX to the predicate Evolut PRO+ system. RESULTS There were 285 cases during Stage I from June 24 to August 12, 2022, and 254 cases during Stage II from August 15 to September 11, 2022. Overall, the cusp overlap technique was used in 88.6 %, and commissural alignment was achieved in 96.1 % of these cases. Compared to implanter's previous experience with the Evolut PRO+ system, less resistance was noted with the Evolut FX system: in 83.0 % of cases during vascular insertion, in 84.7 % of cases while tracking through the vasculature, in 84.4 % of cases while traversing over the arch, and 76.1 % of cases in advancing across the valve. Better symmetry of valve depth was observed in 423 of 525 cases (80.6 %). CONCLUSION Evolut FX system design modifications translated into improvements in catheter deliverability, deployment symmetry and stability, and commissural alignment as assessed by experienced self-expanding and balloon expandable operators.

Abstract
BACKGROUND The fourth-generation mitral transcatheter edge-to-edge repair (M-TEER) device introduced an improved clip deployment sequence, independent leaflet grasping, and 2 wider clip sizes to tailor the treatment of patients with mitral regurgitation (MR) for a broad range of anatomies. The 30-day safety and effectiveness of the fourth-generation M-TEER device were previously demonstrated. OBJECTIVES The aim of this study was to evaluate 1-year outcomes in a contemporary, real-world cohort of subjects treated with the MitraClip G4 system. METHODS EXPAND G4 is an ongoing prospective, multicenter, international, single-arm study that enrolled subjects with primary and secondary MR. One-year outcomes included MR severity (echocardiographic core laboratory assessed), heart failure hospitalization, all-cause mortality, functional capacity (NYHA functional class), and quality of life (Kansas City Cardiomyopathy Questionnaire). RESULTS A total of 1,164 subjects underwent M-TEER from 2020 to 2022. At 1 year, there was a durable reduction in MR to mild or less in 92.6% and to none or trace in 44.2% (P < 0.0001 vs baseline). Few subjects had major adverse events through 1 year (<2% for myocardial infarction, surgical reintervention, or single-leaflet device attachment). The 1-year Kaplan-Meier estimates for all-cause mortality and heart failure hospitalization were 12.3% and 16.9%. Significant improvements in functional capacity (NYHA functional class I or II in 82%; P < 0.0001 vs baseline) and quality of life (18.5-point Kansas City Cardiomyopathy Questionnaire overall summary score improvement; P < 0.0001) were observed. CONCLUSIONS M-TEER with the fourth-generation M-TEER device was safe and effective at 1 year, with durable reductions in MR severity to ≤1+ in more than 90% of patients and concomitant improvements in functional status and quality of life.

Abstract
BACKGROUND Coronary accessibility following redo-transcatheter aortic valve replacement (redo-TAVR) is increasingly important, particularly in younger low-risk patients. This study aimed to predict coronary accessibility after simulated Sapien-3 balloon-expandable valve implantation within an Evolut supra-annular, self-expanding valve using pre-TAVR computed tomography (CT) imaging. METHODS A total of 219 pre-TAVR CT scans from the Evolut Low-Risk CT substudy were analyzed. Virtual Evolut and Sapien-3 valves were sized using CT-based diameters. Two initial Evolut implant depths were analyzed, 3 and 5 mm. Coronary accessibility was evaluated for 2 Sapien-3 in Evolut implant positions: Sapien-3 outflow at Evolut node 4 and Evolut node 5. RESULTS With a 3-mm initial Evolut implant depth, suitable coronary access was predicted in 84% of patients with the Sapien-3 outflow at Evolut node 4, and in 31% of cases with the Sapien-3 outflow at Evolut node 5 (P<0.001). Coronary accessibility improved with a 5-mm Evolut implant depth: 97% at node 4 and 65% at node 5 (P<0.001). When comparing 3- to 5-mm Evolut implant depth, sinus sequestration was the lowest with Sapien-3 outflow at Evolut node 4 (13% versus 2%; P<0.001), and the highest at Evolut node 5 (61% versus 32%; P<0.001). CONCLUSIONS Coronary accessibility after Sapien-3 in Evolut redo-TAVR relates to the initial Evolut implant depth, the Sapien-3 outflow position within the Evolut, and the native annular anatomy. This CT-based quantitative analysis may provide useful information to inform and refine individualized preprocedural CT planning of the initial TAVR and guide lifetime management for future coronary access after redo-TAVR.

Abstract
BACKGROUND With increasing numbers of patients undergoing transcatheter aortic valve replacement (TAVR), data on management of failed TAVR, including repeat TAVR procedure, are needed. The aim of this study was to assess the safety and efficacy of redo-TAVR in a national registry. METHODS This study included all consecutive patients in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry from Nov 9, 2011, to Dec 30, 2022 who underwent TAVR with balloon-expandable valves in failed transcatheter heart valves (redo-TAVR) or native aortic valves (native-TAVR). Procedural, echocardiographic, and clinical outcomes were compared between redo-TAVR and native-TAVR cohorts using propensity score matching. FINDINGS Among 350 591 patients (1320 redo-TAVR; 349 271 native-TAVR), 1320 propensity-matched pairs of patients undergoing redo-TAVR and native-TAVR were analysed (redo-TAVR cohort: mean age 78 years [SD 9]; 559 [42·3%] of 1320 female, 761 [57·7%] male; mean predicted surgical risk of 30-day mortality 8·1%). The rates of procedural complications of redo-TAVR were low (coronary compression or obstruction: four [0·3%] of 1320; intraprocedural death: eight [0·6%] of 1320; conversion to open heart surgery: six [0·5%] of 1319) and similar to native-TAVR. There was no significant difference between redo-TAVR and native-TAVR populations in death at 30 days (4·7% vs 4·0%, p=0·36) or 1 year (17·5% vs 19·0%, p=0·57), and stroke at 30 days (2·0% vs 1·9%, p=0·84) or 1 year (3·2% vs 3·5%, p=0·80). Redo-TAVR reduced aortic valve gradients at 1 year, although they were higher in the redo-TAVR group compared with the native-TAVR group (15 mm Hg vs 12 mm Hg; p<0·0001). Moderate or severe aortic regurgitation rates were similar between redo-TAVR and native-TAVR groups at 1 year (1·8% vs 3·3%, p=0·18). Death or stroke after redo-TAVR were not significantly affected by the timing of redo-TAVR (before or after 1 year of index TAVR), or by index transcatheter valve type (balloon-expandable or non-balloon-expandable). INTERPRETATION Redo-TAVR with balloon-expandable valves effectively treated dysfunction of the index TAVR procedure with low procedural complication rates, and death and stroke rates similar to those in patients with a similar clinical profile and predicted risk undergoing TAVR for native aortic valve stenosis. Redo-TAVR with balloon-expandable valves might be a reasonable treatment for failed TAVR in selected patients. FUNDING Edwards Lifesciences.

Abstract
BACKGROUND The CLASP IID (Edwards PASCAL TrAnScatheter Valve RePair System Pivotal Clinical) trial is the first randomized controlled trial comparing the PASCAL system and the MitraClip system in prohibitive risk patients with significant symptomatic degenerative mitral regurgitation (DMR). OBJECTIVES The study sought to report primary and secondary endpoints and 1-year outcomes for the full cohort of the CLASP IID trial. METHODS Prohibitive-risk patients with 3+/4+ DMR were randomized 2:1 (PASCAL:MitraClip). One-year assessments included secondary effectiveness endpoints (mitral regurgitation [MR] ≤2+ and MR ≤1+), and clinical, echocardiographic, functional, and quality-of-life outcomes. Primary safety (30-day composite major adverse events [MAE]) and effectiveness (6-month MR ≤2+) endpoints were assessed for the full cohort. RESULTS Three hundred patients were randomized (PASCAL: n = 204; MitraClip: n = 96). At 1 year, differences in survival, freedom from heart failure hospitalization, and MAE were nonsignificant (P > 0.05 for all). Noninferiority of the PASCAL system compared with the MitraClip system persisted for the primary endpoints in the full cohort (For PASCAL vs MitraClip, the 30-day MAE rates were 4.6% vs 5.4% with a rate difference of -0.8% and 95% upper confidence bound of 4.6%. The 6-month MR≤2+ rates were 97.9% vs 95.7% with a rate difference of 2.2% and 95% lower confidence bound (LCB) of -2.5%, for, respectively). Noninferiority was met for the secondary effectiveness endpoints at 1 year (MR≤2+ rates for PASCAL vs MitraClip were 95.8% vs 93.8% with a rate difference of 2.1% and 95% LCB of -4.1%. The MR≤1+ rates were 77.1% vs 71.3% with a rate difference of 5.8% and 95% LCB of -5.3%, respectively). Significant improvements in functional classification and quality of life were sustained in both groups (P <0.05 for all vs baseline). CONCLUSIONS The CLASP IID trial full cohort met primary and secondary noninferiority endpoints, and at 1 year, the PASCAL system demonstrated high survival, significant MR reduction, and sustained improvements in functional and quality-of-life outcomes. Results affirm the PASCAL system as a beneficial therapy for prohibitive-surgical-risk patients with significant symptomatic DMR.

Abstract
Transaxillary access has been the most frequently used nonfemoral access route for transcatheter aortic valve replacement (TAVR) with a self-expanding valve. Use of transcarotid TAVR is increasing; however, comparative data on these methods are limited. We compared outcomes following transcarotid or transaxillary TAVR with a self-expanding, supra-annular valve. Methods The Transcatheter Valve Therapy Registry was queried for TAVR procedures using transaxillary and transcarotid access between July 2015 and June 2021. Patients received a self-expanding Evolut R, PRO, or PRO + valve (Medtronic) and had 1-year follow-up. Thirty-day and 1-year outcomes were compared in transcarotid and transaxillary groups after 1:2 propensity score-matching. Multivariable regression models were fitted to identify predictors of key end points. Results The propensity score-matched cohort included 576 patients receiving transcarotid and 1142 receiving transaxillary access. Median procedure time (99 vs 118 minutes; P < .001) and hospital stay (2 vs 3 days; P < .001) were shorter with transcarotid versus transaxillary access. At 30 days, patients with transcarotid access had similar mortality (Kaplan-Meier estimates 3.7% vs 4.3%, P = .57) but significantly lower stroke (3.1% vs 5.9%; P = .017) and mortality or stroke (6.0% vs 8.9%; P = .033) compared with patients receiving transaxillary access. Similar differences were observed at 1 year. Transaxillary access was associated with increased risk of 30-day stroke (hazard ratio, 2.14; 95% confidence interval, 1.27-3.58) by multivariable regression analysis. Conclusions Transcarotid versus transaxillary access for TAVR using a self-expanding valve is associated with procedural benefits and significantly lower stroke and mortality or stroke at 30 days. In patients with unsuitable femoral anatomy, transcarotid access may be the preferred delivery route for self-expanding valves.

Abstract
BACKGROUND Real-world applicability of the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) randomized controlled trial (RCT) has been debated because of careful patient selection and the contrasting results of the MITRA-FR (Multicentre Study of Percutaneous Mitral Valve Repair MitraClip Device in Patients with Severe Secondary Mitral Regurgitation) RCT. OBJECTIVES The COAPT-PAS (COAPT Post-Approval Study) was initiated to assess the safety and effectiveness of the MitraClip in patients with secondary mitral regurgitation (SMR). METHODS COAPT-PAS is a prospective, single-arm, observational study of 5,000 consecutive patients with SMR treated with the MitraClip at 406 U.S. centers participating in the TVT (Transcatheter Valve Therapy) registry from 2019 to 2020. The 1-year outcomes from the COAPT-PAS full cohort and the COAPT-like and MITRA-FR-like subgroups who met RCT inclusion/exclusion criteria are reported. RESULTS Patients in the COAPT-PAS had more comorbidities, more severe HF and functional limitations, and less guideline-directed medical therapy than those in the COAPT or MITRA-FR RCTs. Patients in the COAPT-PAS full cohort and the COAPT-like (n = 991) and MITRA-FR-like (n = 917) subgroups achieved a 97.7% MitraClip implant rate, a similar and durable reduction of mitral regurgitation to ≤2+ at 1 year (90.7%, 89.7%, and 86.6%, respectively), a large improvement in quality of life at 1 year (Kansas City Cardiomyopathy Questionnaire +29 COAPT-PAS, +27 COAPT-like, and +33 MITRA-FR-like), faster procedure times, similar or lower clinical event rates compared with the RCTs' MitraClip arms, and lower clinical event rates than the RCTs' guideline-directed medical therapy only arms. One-year heart failure hospitalizations was 18.9% in COAPT-PAS, 19.7% in COAPT-like compared with 24.9% in COAPT-RCT, and 28.7% in COAPT-PAS-MITRA-FR-like compared with 47.4% in MITRA-FR-RCT. CONCLUSIONS This large, contemporary, real-world study reinforces the safety and effectiveness of the MitraClip System in patients with SMR, including those who met the COAPT or MITRA-FR RCT inclusion/exclusion criteria and patients excluded from the RCTs.

Abstract
BACKGROUND Anatomical and clinical criteria to define mitral transcatheter edge-to-edge repair (TEER) "unsuitability" have been proposed on the basis of a Heart Valve Collaboratory consensus opinion from physician experience with early-generation TEER devices but lacked an evidence-based approach. OBJECTIVES The aim of this study was to explore the spectrum of TEER suitability using echocardiographic and clinical outcomes from the EXPAND G4 real-world postapproval study. METHODS EXPAND G4 is a global, prospective, multicenter, single-arm study that enrolled 1,164 subjects with mitral regurgitation (MR) treated with the MitraClip G4 System. Three groups were defined using the Heart Valve Collaboratory TEER unsuitability criteria: 1) risk of stenosis (RoS); 2) risk of inadequate MR reduction (RoIR); and 3) subjects with baseline moderate or less MR (MMR). A TEER-suitable (TS) group was defined by the absence of these characteristics. Endpoints included independent core laboratory-assessed echocardiographic characteristics, procedural outcomes, MR reduction, NYHA functional class, Kansas City Cardiomyopathy Questionnaire score, and major adverse events through 30 days. RESULTS Subjects in the RoS (n = 56), RoIR (n = 54), MMR (n = 326), and TS (n = 303) groups had high 30-day MR reduction rates (≤1+: RoS 97%, MMR 93%, and TS 91%; ≤2+: RoIR 94%). Thirty-day improvements in functional capacity (NYHA functional class I or II at 30 days vs baseline: RoS 94% vs 29%, RoIR 88% vs 30%, MMR 79% vs 26%, and TS 83% vs 33%) and quality of life (change in Kansas City Cardiomyopathy Questionnaire score: RoS +27 ± 26, RoIR +16 ± 26, MMR +19 ± 26, and TS +19 ± 24) were safely achieved in all groups, with low major adverse events (<3%) and all-cause mortality (RoS 1.8%, RoIR 0%, MMR 1.5%, and TS 1.3%). CONCLUSIONS Patients previously deemed TEER unsuitable can be safely and effectively treated with the mitral TEER fourth-generation device.

Abstract
BACKGROUND The fourth-generation MitraClip G4 System builds on the previous NTR/XTR system with additional wider clip sizes (NTW and XTW), an independent grasping feature, and an improved clip deployment sequence. OBJECTIVES The primary objective of this study was to assess the safety and performance of the MitraClip G4 System within a contemporary real-world setting. METHODS EXPAND G4 is a prospective, multicenter, international, single-arm, postapproval study that enrolled patients with primary (degenerative) mitral regurgitation (MR) and secondary (functional) MR at 60 centers. Follow-up of the full cohort has been conducted through 30 days. Echocardiograms were analyzed by an echocardiography core laboratory. Study outcomes included MR severity, functional capacity measured by NYHA functional class, quality of life measured using the Kansas City Cardiomyopathy Questionnaire, major adverse event rates, and all-cause mortality. RESULTS In EXPAND G4, 1,141 subjects with primary MR and secondary MR were treated from March 2021 to February 2022. Implantation and acute procedural success rates were 98.0% and 96.2%, respectively, with a mean of 1.4 ± 0.6 clips implanted per subject. MR was significantly reduced at 30 days compared with baseline (98% achieved MR ≤ 2+, and 91% achieved MR ≤ 1+; P < 0.0001). Functional capacity and quality of life were substantially improved, with 83% of patients achieving NYHA functional class I or II. Likewise, an 18-point improvement was observed in Kansas City Cardiomyopathy Questionnaire summary scores compared with baseline. The composite major adverse event rate was 2.7%, and the all-cause death rate was 1.3% at 30 days. CONCLUSIONS This study demonstrates for the first time the effectiveness and safety of MitraClip G4 System at 30 days in a cohort of >1,000 patients with MR in a contemporary, real-world setting.

Abstract
An increasing number of patients with mitral valve disease are high risk for surgery and in need of less invasive treatments including transcatheter mitral valve replacement (TMVR). Left ventricular outflow tract (LVOT) obstruction is a predictor of poor outcome after TMVR, and its risk can be accurately predicted using cardiac computed tomography analysis. Novel treatment strategies that have shown efficacy in reducing risk of LVOT obstruction after TMVR include pre-emptive alcohol septal ablation, radiofrequency ablation, and anterior leaflet electrosurgical laceration. This review describes recent advances in the management of LVOT obstruction risk after TMVR, provides a new management algorithm, and explores forthcoming studies that will further advance the field.

Abstract
INTRODUCTION There is a need for quality medical care for children injured in conflict, but a description of injuries and injury burden from blast and ballistic mechanisms is lacking. The radiology records of children imaged during the war in Afghanistan represent a valuable source of information about the patterns of paediatric conflict injuries. METHODS The UK military radiological database was searched for all paediatric presentations to Camp Bastion during 2011. Reports and original images were reviewed to determine location and severity of injuries sustained. Additional information was obtained from imaging request forms and the Joint Theatre Trauma Register, a database of those treated at UK medical facilities in Iraq and Afghanistan. RESULTS Radiology was available for 219 children. 71% underwent CT scanning. 46% suffered blast injury, 22% gunshot wounds (GSWs), and 32% disease and non-battle injuries (DNBIs). 3% had penetrating head injury, 11% penetrating abdominal trauma and 8% lower limb amputation, rates far exceeding those found in civilian practice. Compared with those with DNBI, those with blast or GSW were more likely to have serious (Abbreviated Injury Score, AIS, ≥3) injuries (median no. AIS ≥3 injuries were 1 for blast, 1 for GSW and 0 for DNBI, p<0.05) and children exposed to blast were more likely to have multiple body regions with serious injuries (OR for multiple AIS ≥3 injuries for blast vs DNBI=5.811 CI [1.877 to 17.993], p<0.05). CONCLUSIONS Paediatric conflict injuries are severe, and clinicians used only to civilian practice may be unprepared for the nature and severity of injuries inflicted on children in conflict. Whole-body CT for those with conflict-related injuries, especially blast, is hugely valuable. We recommend that CT is used for paediatric assessment in blast and ballistic incidents and that national imaging guidelines amend the threshold for doing so.

Abstract
BACKGROUND Procedural success and clinical outcomes after transcatheter aortic valve replacement (TAVR) have improved, but residual aortic regurgitation (AR) and new permanent pacemaker implantation (PPI) rates remain variable because of a lack of uniform periprocedural management and implantation. OBJECTIVES The Optimize PRO study evaluates valve performance and procedural outcomes using an "optimized" TAVR care pathway and the cusp overlap technique (COT) in patients receiving the Evolut PRO/PRO+ (Medtronic) self-expanding valves. METHODS Optimize PRO, a nonrandomized, prospective, postmarket study conducted in the United States, Canada, Europe, Middle East, and Australia, is enrolling patients with severe symptomatic aortic stenosis and no pre-existing pacemaker. Sites follow a standardized TAVR care pathway, including early discharge and a conduction disturbance management algorithm, and transfemoral deployment using the COT. RESULTS A total of 400 attempted implants from the United States and Canada comprised the main cohort of this second interim analysis. The mean age was 78.7 ± 6.6 years, and the mean Society of Thoracic Surgeons predictive risk of mortality was 3.0 ± 2.4. The median length of stay was 1 day. There were no instances of moderate or severe AR at discharge. At 30 days, all-cause mortality or stroke was 3.8%, all-cause mortality was 0.8%, disabling stroke was 0.7%, hospital readmission was 10.1%, and cardiovascular rehospitalization was 6.1%. The new PPI rate was 9.8%, 5.8% with 4-step COT compliance. In the multivariable model, right bundle branch block and the depth of the implant increased the risk of PPI, whereas using the 4-step COT lowered 30-day PPI. CONCLUSIONS The use of the TAVR care pathway and COT resulted in favorable clinical outcomes with no moderate or severe AR and low PPI rates at 30 days while facilitating early discharge and reproducible outcomes across various sites and operators.

Abstract
BACKGROUND The third-generation MitraClip NTR/XTR transcatheter edge-to-edge repair system was introduced to assist in leaflet grasping with the longer clip arms of MitraClip XTR and to improve ease of use with the modified delivery catheter. OBJECTIVES The EXPAND study evaluated contemporary real-world outcomes in subjects with mitral regurgitation (MR) treated with the third-generation MitraClip NTR/XTR transcatheter edge-to-edge repair system. METHODS EXPAND is a prospective, multicenter, international, single-arm study that enrolled patients with primary MR and secondary MR at 57 centers. Follow-up was conducted through 12 months. Echocardiograms were analyzed by an echocardiographic core laboratories. Study outcomes included: MR severity, functional capacity measured by New York Heart Association functional class, quality of life measured by Kansas City Cardiomyopathy Questionnaire, heart failure hospitalizations, all-cause mortality. RESULTS 1,041 patients were enrolled from April 2018 through March 2019, of which 50.5% had primary or mixed etiology. Implant success was 98.9%; 1.5 ± 0.6 clips were implanted per subject. Significant MR reduction from baseline (≥MR 3+: 56.0%) to 30 days (≤MR 1+:88.8%) was maintained through 1 year (MR ≤1+: 89.2%). A total of 84.5% and 93.0% of subjects in primary MR and secondary MR, respectively, had ≤1+ MR at 1 year. Significant improvements were observed in clinical outcomes (New York Heart Association functional class I/II in 80.3%, +21.6 improvement in Kansas City Cardiomyopathy Questionnaire score) at 1 year. All-cause mortality and heart failure hospitalizations at 1 year were 14.9% and 18.9%, respectively, which was significantly lower than previous studies. CONCLUSIONS The study demonstrates treatment with the third-generation system resulted in substantial reduction of MR in a contemporary real-world practice, compared with the results of earlier EVEREST and COAPT trials.(The MitraClip® EXPAND Study of the Next Generation of MitraClip® Devices [EXPAND]; NCT03502811).

Abstract
AIMS Mitral valve transcatheter edge-to-edge repair is a guideline-recommended treatment option for patients with secondary mitral regurgitation (SMR). The purpose of this analysis was to report contemporary real-world outcomes in SMR patients treated with third-generation MitraClip systems. METHODS AND RESULTS EXPAND is a prospective, multicentre, international, single-arm study with 1041 patients treated for mitral regurgitation (MR) with MitraClip NTR/XTR, with 30-day and 1-year follow-up. All echocardiograms were analysed by an independent echocardiographic core lab. Study outcomes included procedural outcomes, durability of MR reduction, and major adverse events including all-cause mortality and heart failure hospitalizations (HFH). A subgroup of 413 symptomatic patients (age 74.7 ± 10.1 years, 58% male) with severe SMR were included. MR reduction to MR ≤ 1+ and MR ≤ 2+ was achieved in 93.0% and 98.5% of patients, respectively, which was sustained at 1-year follow-up. All-cause mortality was 17.7% at 1-year- follow-up, and the combined endpoint of all-cause mortality or first HFH occurred in 34% of patients. This combined endpoint was significantly less frequently observed in MR ≤ 1+ patients (Kaplan-Maier estimates: 29.7% vs. 69.6% for MR ≤ 1+ vs. MR ≥ 2 +; p < 0.0001). New York Heart Association (NYHA) functional class improved significantly from baseline (NYHA ≤ II: 17%) to 1-year follow-up (NYHA ≤ II: 78%) (p < 0.0001). While MR reduction was comparable between NTR-only vs. XTR-only treated patients, less XTR clips were required for achieving MR reduction. CONCLUSIONS Under real-world conditions, optimal sustained MR reduction to MR ≤ 1+ was achieved in a high percentage of patients with third-generation MitraClip, which translated into symptomatic improvement and low event rates. These results appear to be comparable with recent randomized clinical trials.

Abstract
OBJECTIVES The aim of this study was to compare transcaval and transaxillary artery access for transcatheter aortic valve replacement (TAVR) at experienced medical centers in contemporary practice. BACKGROUND There are no systematic comparisons of transcaval and transaxillary TAVR access routes. METHODS Eight experienced centers contributed local data collected for the STS/ACC TVT Registry (Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry) between 2017 and 2020. Outcomes after transcaval and axillary/subclavian (transaxillary) access were adjusted for baseline imbalances using doubly robust (inverse propensity weighting plus regression) estimation and compared. RESULTS Transcaval access was used in 238 procedures and transaxillary access in 106; for comparison, transfemoral access was used in 7,132 procedures. Risk profiles were higher among patients selected for nonfemoral access but similar among patients requiring transcaval and transaxillary access. Stroke and transient ischemic attack were 5-fold less common after transcaval than transaxillary access (2.5% vs 13.2%; OR: 0.20; 95% CI: 0.06-0.72; P = 0.014) compared with transfemoral access (1.7%). Major and life-threatening bleeding (Valve Academic Research Consortium 3 ≥ type 2) were comparable (10.0% vs 13.2%; OR: 0.66; 95% CI: 0.26-1.66; P = 0.38) compared with transfemoral access (3.5%), as was blood transfusion (19.3% vs 21.7%; OR: 1.07; 95% CI: 0.49-2.33; P = 0.87) compared with transfemoral access (7.1%). Vascular complications, intensive care unit and hospital length of stay, and survival were similar between transcaval and transaxillary access. More patients were discharged directly home and without stroke or transient ischemic attack after transcaval than transaxillary access (87.8% vs 62.3%; OR: 5.19; 95% CI: 2.45-11.0; P < 0.001) compared with transfemoral access (90.3%). CONCLUSIONS Patients undergoing transcaval TAVR had lower rates of stroke and similar bleeding compared with transaxillary access in a contemporary experience from 8 US centers. Both approaches had more complications than transfemoral access. Transcaval TAVR access may offer an attractive option.

Abstract
OBJECTIVES We report the 30-day outcomes from the roll-in cohort of the CLASP IID trial, representing the first procedures performed by each site. BACKGROUND The currently enrolling CLASP IID/IIF pivotal trial is a multicenter, prospective, randomized trial assessing the safety and effectiveness of the PASCAL transcatheter valve repair system in patients with clinically significant MR. The trial allows for up to three roll-in patients per site. METHODS Eligibility criteria were: DMR ≥3+, prohibitive surgical risk, and deemed suitable for transcatheter repair by the local heart team. Trial oversight included a central screening committee and echocardiographic core laboratory. The primary safety endpoint was a 30-day composite MAE: cardiovascular mortality, stroke, myocardial infarction (MI), new need for renal replacement therapy, severe bleeding, and non-elective mitral valve re-intervention, adjudicated by an independent clinical events committee. Thirty-day echocardiographic, functional, and quality of life outcomes were assessed. RESULTS A total of 45 roll-in patients with mean age of 83 years and 69% in NYHA class III/IV were treated. Successful implantation was achieved in 100%. The 30-day composite MAE rate was 8.9% including one cardiovascular death (2.2%) due to severe bleeding from a hemorrhagic stroke, one MI, and no need for re-intervention. MR≤1+ was achieved in 73% and ≤2+ in 98% of patients. 89% of patients were in NYHA class I/II (p < .001) with improvements in 6MWD (30 m; p = .054) and KCCQ (17 points; p < .001). CONCLUSIONS Early results representing sites with first experience with the PASCAL repair system showed favorable 30-day outcomes in patients with DMR≥3+ at prohibitive surgical risk.

Abstract
BACKGROUND Prospective bicuspid low-risk transcatheter aortic valve replacement (TAVR) registries' data demonstrated encouraging short-term results. Detailed data on transcatheter heart valve (THV) geometry after deployment using contemporary devices are lacking. This study sought to examine valve geometry after TAVR in patients with bicuspid aortic stenosis (AS). METHODS The study population was patients from the LRT (Low Risk TAVR) trial who underwent TAVR using the SAPIEN 3 THV for bicuspid and tricuspid AS. THV geometry measured on 30-day computed tomography (CT) included valve height, angle, depth, and eccentricity. Additionally, THV hemodynamics and outcomes post-TAVR were compared among patients with bicuspid and tricuspid AS. RESULTS A total of 107 patients from the LRT trial using the SAPIEN 3 THV were included in our analysis. On 30-day CT, the valve height ratio (1.07 vs. 1.07; p = 0.348), depths (right [5.6 mm vs. 6.2 mm; p = 0.223], left [5.3 mm vs. 4.4 mm; p = 0.082] and non [4.8 mm vs. 4.5 mm; p = 0.589] coronary cusps), eccentricities (1.08 vs. 1.07; p = 0.9550), and angles (except the right [3.9 degrees vs. 6.3 degrees; p = 0.003] and left [3.6 degrees vs. 6.0 degrees; p = 0.007]) were similar between bicuspid and tricuspid patients. Hemodynamics, stroke, and mortality were similar at 1 year. CONCLUSION Despite challenging bicuspid anatomy of the aortic valve, our comprehensive CT analysis supports similar THV geometry between patients with bicuspid and tricuspid AS undergoing TAVR using the SAPIEN 3 THV in low-risk patients. This translated to excellent short-term clinical outcomes and THV hemodynamics in both aortic valve morphologies. TRIAL REGISTRY NCT02628899, https://clinicaltrials.gov/ct2/show/NCT02628899.

Abstract
OBJECTIVES This study sought to determine the safety of the BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) procedure. BACKGROUND Transcatheter aortic valve replacement causes coronary artery obstruction in 0.7% of cases, with 40% to 50% mortality. BASILICA is a procedure to prevent coronary obstruction. Safety and feasibility in a large patient cohort is lacking. METHODS The international BASILICA registry was a retrospective, multicenter, real-world registry of patients at risk of coronary artery obstruction undergoing BASILICA and transcatheter aortic valve replacement. Valve Academic Research Consortium-2 definitions were used to adjudicate events. RESULTS Between June 2017 and December 2020, 214 patients were included from 25 centers in North America and Europe; 72.8% had bioprosthetic aortic valves and 78.5% underwent solo BASILICA. Leaflet traversal was successful in 94.9% and leaflet laceration in 94.4%. Partial or complete coronary artery obstruction was seen in 4.7%. Procedure success, defined as successful BASILICA traversal and laceration without mortality, coronary obstruction, or emergency intervention, was achieved in 86.9%. Thirty-day mortality was 2.8% and stroke was 2.8%, with 0.5% disabling stroke. Thirty-day death and disabling stroke were seen in 3.4%. Valve Academic Research Consortium-2 composite safety was achieved in 82.8%. One-year survival was 83.9%. Outcomes were similar between solo and doppio BASILICA, between native and bioprosthetic valves, and with the use of cerebral embolic protection. CONCLUSIONS BASILICA is safe, with low reported rates of stroke and death. BASILICA is feasible in the real-world setting, with a high procedure success rate and low rates of coronary artery obstruction.

Abstract
OBJECTIVES The purpose of this study was to evaluate tip-to-base intentional laceration of the anterior mitral leaflet to prevent left ventricular outflow tract obstruction (LAMPOON) in patients undergoing transcatheter mitral valve replacement (TMVR) in annuloplasty rings or surgical mitral valves. BACKGROUND LAMPOON is an effective adjunct to TMVR that prevents left ventricular outflow tract obstruction (LVOTO). Laceration is typically performed from the base to the tip of the anterior mitral leaflet. A modified laceration technique from leaflet tip to base may be effective in patients with a prosthesis that protects the aortomitral curtain. METHODS This is a multicenter, 21-patient, consecutive retrospective observational cohort. Patients underwent tip-to-base LAMPOON to prevent LVOTO and leaflet overhang, or therapeutically to lacerate a long anterior mitral leaflet risking or causing LVOTO. Outcomes were compared with findings from patients in the LAMPOON investigational device exemption trial with a prior mitral annuloplasty. RESULTS Twenty-one patients with a annuloplasty or valve prosthesis-protected mitral annulus underwent tip-to-base LAMPOON (19 preventive, 2 rescue). Leaflet laceration was successful in all and successfully prevented or treated LVOTO in all patients. No patients had significant LVOTO upon discharge. There were 2 cases of unintentional aortic valve injury (1 patient underwent emergency transcatheter aortic valve replacement and 1 patient underwent urgent surgical aortic valve replacement). In both cases, the patients had a supra-annular ring annuloplasty, and the retrograde aortic guiding catheter failed to insulate the guidewire lacerating surface from the aortic root. All patients survived to 30 days. Compared with classic retrograde LAMPOON, there was a trend toward shorter procedure time. CONCLUSIONS Tip-to-base laceration is a simple, effective, and safe LAMPOON variant applicable to patients with an appropriately positioned mitral annular ring or bioprosthetic valve. Operators should take care to insulate the lacerating surface from adjacent structures.

Abstract
BACKGROUND The optimal antithrombotic regimen after transcatheter aortic valve replacement remains unclear. METHODS In this randomized open-label study, low-risk patients undergoing transfemoral transcatheter aortic valve replacement at 7 centers in the United States were randomized 1:1 to low-dose aspirin or warfarin plus low-dose aspirin for 30 days. Patients who could not be randomized were enrolled in a separate registry. Computed tomography or transesophageal echocardiography was performed at 30 days. The primary effectiveness end point was a composite of the following at 30 days: hypoattenuated leaflet thickening, at least moderately reduced leaflet motion, hemodynamic dysfunction (mean aortic valve gradient ≥20 mm Hg, effective orifice area ≤1.0 cm2, dimensionless valve index <0.35, or moderate or severe aortic regurgitation), stroke, or transient ischemic attack. RESULTS Between July 2018 and October 2019, 94 patients were randomly assigned, 50 to aspirin and 44 to warfarin plus aspirin, and 30 were enrolled into the registry. In the intention-to-treat analysis of the randomized cohort, the composite primary effectiveness end point was met in 26.5% for aspirin versus 7.0% for warfarin plus aspirin (P=0.014; odds ratio, 4.8 [95% CI, 1.3-18.3]). The rate of hypoattenuated leaflet thickening was 16.3% for aspirin versus 4.7% for warfarin plus aspirin (P=0.07; odds ratio, 4.0 [95% CI, 0.8-20.0]). There was no excess bleeding at 30 days with anticoagulation. In the as-treated analysis of pooled randomized and registry cohorts, the rate of hypoattenuated leaflet thickening was 16.7% for aspirin versus 3.1% for warfarin plus aspirin (P=0.011; odds ratio, 6.3 [95% CI, 1.3-30.6]). CONCLUSIONS In low-risk transcatheter aortic valve replacement patients, anticoagulation with warfarin may prevent transcatheter heart valve dysfunction in the short term without excess bleeding.

Abstract
BACKGROUND Multiple alternative access routes have been employed for patients with contraindications to standard transfemoral transcatheter aortic valve replacement (TAVR); however, the optimal route for alternative access approaches is not established. In order to better understand possible differences in alternative access routes, we compared the procedural efficacy and outcomes at 30 days and 1 year in patients who underwent TAVR via subclavian (SC) or transcaval (TC) access route at a single, tertiary-care center. METHODS This retrospective analysis included all TAVR procedures performed via SC or TC approaches between December 2011 to January 2020, with outcomes reported to 1 year post procedure. Additional safety and feasibility studies, including successful device deployment, procedural time, blood loss, and total hospitalization length, are included as part of this study. RESULTS A total of 41 patients underwent SC access and 22 patients underwent TC access for TAVR. Between both cohorts, SC patients were older at the time of TAVR (83.2 ± 3.7 years for SC vs 80.7 ± 3.9 years for TC; P=.03) and all patients were previously deemed high or prohibitive surgical risk (Society of Thoracic Surgeons score, aortic valve replacement only: 10.4 ± 2.6% for SC vs 9.0 ± 1.9% for TC; P=.12), with similar preoperative hemodynamic profiles. PROCEDURAL SAFETY Device deployment was successful in all patients in both groups, with longer procedural times noted in the SC cohort (62.1 ± 12.1 minutes for SC vs 39.8 ± 12.5 minutes for TC; P<.05). There were no in-hospital deaths in the SC group and 1 intraoperative death in the TC group that was unrelated to access route. Average length of hospital stay was consistent between the two groups (3.8 ± 1.4 days for SC vs 3.4 ± 1.1 days for TC; P=.06). More cerebrovascular accidents were noted in the SC group at 30 days (6 for SC vs 1 for TC), 6 months (3 for SC vs 0 for TC), and 1 year (2 for SC vs 0 for TC), with more postprocedural permanent pacemakers implanted in the SC group at 30 days (9 for SC vs 3 for TC; P<.05, but with fewer at 6 months (2 for SC vs 3 for TC) and 1 year (1 for SC vs 2 for TC). Mortality rate was not statistically different between the two groups at 30 days, 6 months, and 1 year (P>.05 for all). CONCLUSION Both SC and TC access routes can be safe and feasible options for TAVR in patients at increased or prohibitive surgical risk with contraindications to standard transfemoral access.

Abstract
Hypertrophic cardiomyopathy (HCM) is frequently associated with abnormalities of the mitral valve; these commonly include systolic anterior motion (SAM) of anterior mitral leaflets that contribute to dynamic left ventricular outflow tract (LVOT) obstruction and secondary mitral regurgitation (MR). In patients with severe HCM, LVOT obstruction due to SAM, and debilitating symptoms refractory to medical therapy, the current standard of care involves a surgical approach. This involves targeting the ventricular septum through resection or ablation, combined at times with mitral valve replacement or plication of the valve leaflet to relieve LVOT obstruction. In patients with symptoms refractory to medical management who are at prohibitive surgical risk, additional options for less-invasive approaches for the management of HCM are needed. We describe here the successful non-surgical catheter-based management of a 72-year-old woman at high surgical risk, debilitating symptoms refractory to maximal medical management, and severe, diffuse-type HCM. Edge-to-edge repair with MitraClip (Abbott Vascular) was used to target SAM causing dynamic LVOT obstruction, with resulting significant reduction in LVOT gradient and dramatic clinical improvement. Her postprocedure outcomes to 2 years are reported herein. Additionally, we review the current management strategies for HCM management, and include a discussion of minimally invasive options.

Abstract
OBJECTIVES The aim of this study was to characterize the safety profile of an intra-annular self-expanding valve with a next-generation low-profile delivery system (DS). BACKGROUND Key design modifications to the FlexNav DS include the addition of a hydrophilic-coated, integrated sheath and stability layer to facilitate gradual, controlled deployment in vessels with diameter ≥5 mm. METHODS Patients were pooled from 2 concurrent prospective, multicenter, single-arm studies (FlexNav DS arm of PORTICO IDE [Portico Re-Sheathable Transcatheter Aortic Valve System U.S. IDE Trial] [n = 134] and the FlexNav EU CE Mark Study [n = 46]) for the analysis. The primary endpoint was Valve Academic Research Consortium-2-defined major vascular complications at 30 days. Clinical outcomes and valve performance were assessed through 30 days by an independent clinical events committee and an echocardiography core laboratory, respectively. RESULTS One hundred forty high-risk and 40 extreme-risk subjects enrolled between October 15, 2018, and December 10, 2019, from 28 sites in the United States, Australia, and Europe who underwent attempted transfemoral Portico valve implantation were included. The mean age was 85.1 ± 5.6 years, 60% were women, the mean Society of Thoracic Surgeons score was 5.3%, and 96.1% presented with ≥1 frailty factor. Technical device success was 96.7%. At 30 days, the rate of major vascular complications was 5.0%, with 4.4% of complications adjudicated as access site-related (3.3% transcatheter aortic valve replacement DS access site-related). Death (0.6%) and disabling stroke (1.1%) were rare. The rate of new permanent pacemaker implantation was 15.4%. Echocardiography revealed a mean gradient of 7.1 ± 3.2 mm Hg, mean valve area of 1.77 ± 0.41 cm2, and a 4.1% rate of moderate paravalvular leak at 30 days. CONCLUSIONS Portico valve implantation with the FlexNav DS was associated with an excellent safety profile at 30 days.

Abstract
BACKGROUND Patient prosthesis mismatch (PPM) is an iatrogenic complication that occurs in patients who undergo surgical aortic valve replacement (SAVR). PPM occurs when the implanted surgical valve has an effective orifice area (EOA) that is too small for the patient, resulting in a gradient across the valve despite an otherwise normally functioning prosthesis. PPM has been associated with mid- and long-term increased morbidity and mortality. When this occurs, repeat SAVR with root enlargement and implantation of a larger prosthesis is traditionally employed; however, this approach involves the risks of morbidity and mortality of redo surgery, which may be prohibitive in critically ill or medically complex patients. Bioprosthetic valve fracture (BVF), where high-pressure balloon inflation is employed to fracture the surgical valve sewing ring to increase the EOA, has been used as an adjunct for valve-in-valve (transcatheter aortic valve in surgical aortic valve [TAV in SAV]) procedures for degenerated surgical valves to increase EOA, but has not yet been reported as standalone therapy for early PPM after SAVR. CASE PRESENTATION We present a case of a 41-year-old male (body surface area, 2.3 m²) who presented 4 months after SAVR with a 21 mm surgical valve (Magna Ease, true inner diameter, 19 mm) with severe PPM (mean gradient, 43 mm Hg) despite normal functioning valvular prosthetic leaflets, associated with debilitating symptoms. This patient was deemed high risk by the heart team, and was successfully treated with TAV in SAV (26 mm Evolut R) and concomitant high-pressure bioprosthetic valve fracture (BVF) with a 22 mm high-pressure balloon. The patient tolerated the procedure well; mean gradient was 5 mm Hg post BVF and prompt resolution of symptoms was seen. His postprocedure recovery was uneventful and his symptoms resolved, allowing him to return to work within a week of his hospital discharge. BVF associated with TAV in SAV appears to be a feasible approach for treatment of severe symptomatic PPM even in the early postoperative period with otherwise normally functioning prosthesis.

Abstract
In patients with increased surgical risk and hemodynamically significant mitral disease, a transcatheter strategy for mitral valve replacement (TMVR) may be suitable; however, is also not without procedure risk. Obstruction of the left ventricular outflow tract (LVOT) is one of the most dreaded complications of TMVR, requiring careful consideration of potential candidates with preprocedural imaging and ex vivo valvular fit simulation as part of risk assessment for postprocedure obstruction. In patients at high risk of LVOT obstruction, early studies have shown that alcohol septal ablation or electrosurgical laceration of the anterior mitral leaflet (LAMPOON) procedure prior to TMVR may mitigate the risk of LVOT obstruction. We describe the recent successful management of a patient with severe mitral valve disease, mitral annular calcification (MAC), and high risk of post-TMVR LVOT obstruction, who underwent a sequential strategy of ASA followed by electrosurgical leaflet resection with the LAMPOON procedure prior to TMVR to successfully prevent LVOT obstruction. To our knowledge, this is the first time this dual strategy has been reported, and it may allow more patients with severe mitral valve disease to undergo TMVR in the future.

Abstract
BACKGROUND For patients with severe aortic stenosis and coronary artery disease, the completely percutaneous approach to aortic valve replacement and revascularization has not been compared with the standard surgical approach. METHODS The prospective SURTAVI trial (Safety and Efficiency Study of the Medtronic CoreValve System in the Treatment of Severe, Symptomatic Aortic Stenosis in Intermediate Risk Subjects Who Need Aortic Valve Replacement) enrolled intermediate-risk patients with severe aortic stenosis from 87 centers in the United States, Canada, and Europe between June 2012 and June 2016. Complex coronary artery disease with SYNTAX score (Synergy Between PCI with Taxus and Cardiac Surgery Trial) >22 was an exclusion criterion. Patients were stratified according to the need for revascularization and then randomly assigned to treatment with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Patients assigned to revascularization in the TAVR group underwent percutaneous coronary intervention, whereas those in the SAVR group had coronary artery bypass grafting. The primary end point was the rate of all-cause mortality or disabling stroke at 2 years. RESULTS Of 1660 subjects with attempted aortic valve implants, 332 (20%) were assigned to revascularization. They had a higher Society of Thoracic Surgeons risk score for mortality (4.8±1.7% versus 4.4±1.5%; P<0.01) and were more likely to be male (65.1% versus 54.2%; P<0.01) than the 1328 patients not assigned to revascularization. After randomization to treatment, there were 169 patients undergoing TAVR and percutaneous coronary intervention, 163 patients undergoing SAVR and coronary artery bypass grafting, 695 patients undergoing TAVR, and 633 patients undergoing SAVR. No significant difference in the rate of the primary end point was found between TAVR and percutaneous coronary intervention and SAVR and coronary artery bypass grafting (16.0%; 95% CI, 11.1-22.9 versus 14.0%; 95% CI, 9.2-21.1; P=0.62), or between TAVR and SAVR (11.9%; 95% CI, 9.5-14.7 versus 12.3%; 95% CI, 9.8-15.4; P=0.76). CONCLUSIONS For patients at intermediate surgical risk with severe aortic stenosis and noncomplex coronary artery disease (SYNTAX score ≤22), a complete percutaneous approach of TAVR and percutaneous coronary intervention is a reasonable alternative to SAVR and coronary artery bypass grafting.

Abstract
BACKGROUND Transcatheter aortic valve replacement (TAVR) has been widely adopted, but outcomes in end-stage renal disease (ESRD) patients on hemodialysis (HD) have not been extensively studied. METHODS A total of 1260 TAVRs were performed at our center between December 2011 and October 2018, including 86 patients (6.82%) with ESRD on HD. Comparisons were made between baseline demographics, preoperative risk, hemodynamics, and reintervention, as well as survival at 30 days, 1 year, and 2 years. RESULTS Age at TAVR was 62.7 ± 12.1 years in the ESRD-HD group vs 72.3 ± 5.9 years in the non-ESRD group (P<.01). STS scores were 10.2 ± 1.3% in the ESRD-HD group vs 8.1 ± 1.1% in the non-ESRD group (P<.01). Mortality rates were different between the ESRD-HD group and the non-ESRD group (30-day mortality, 5.8% vs 3.1%, respectively [P=.05]; 1-year mortality, 25.1% vs 13.6%, respectively [P<.01]; 2-year mortality, 51.6% vs 23.0%, respectively [P<.01]). Baseline aortic valve areas (AVAs) were comparable; however, ESRD-HD patients had higher gradients than non-ESRD patients at every postprocedural interval assessed (30-day AVA, 1.47 ± 0.2 cm² vs 1.32 ± 0.1 cm², respectively [P<.001]; 1-year AVA, 1.39 ± 0.1 cm² vs 1.05 ± 0.1 cm², respectively [P<.01]; 2-year AVA, 1.28 ± 0.1 cm² vs 0.77 ± 0.05 cm² , respectively [P<.01]). Repeat TAVR was needed within 2 years in 5 ESRD-HD patients (6.8%) and 1 non-ESRD patient (0.01%). CONCLUSIONS In our single-center cohort, the ESRD-HD TAVR group demonstrated significantly higher rates of need for valvular reintervention (6.8% vs 0.01%) at 2 years, as well as higher mortality rates at 30 days, 1 year, and 2 years.

Abstract
Case summary A 14-year-old neutered female Burmese cat was referred for investigation of a caudal oropharyngeal mass. CT showed a thin walled cyst-like structure filling and expanding from the right tympanic bulla. Histopathology showed fragments of mildly dysplastic squamous epithelium and aggregates of keratin. These findings were considered consistent with a diagnosis of cholesteatoma. Relevance and novel information To the best of our knowledge, this is the first reported case of a cholesteatoma in a cat. Cholesteatoma should be considered a differential diagnosis for cats presenting with a caudal oropharyngeal mass, a history of chronic ear disease or a history of previous, surgically managed middle ear disease. Advanced imaging and biopsies should be considered important in the diagnosis of these lesions.

Abstract
IntroductionThis paper examines the pain management, from surgery to specialist rehabilitation, of the first seven military transfemoral amputee patients treated in the UK with femoral osseointegration. All the patients had sustained complex ballistic injuries on the battlefield. The patients were characterised by long-standing problems with functional rehabilitation due to limitations with conventional prostheses, including stump soft tissue issues and impaired biomechanics.MethodsA prospective service investigation was undertaken to evaluate the effectiveness of the pain management of patients undergoing osseointegration. Data were collected by daily direct patient contact, supplemented by a focused review of perioperative and rehabilitation case notes. Physiological and medication details were recorded with specific reference to systemic and regional analgesia and the impact of postoperative complications, including infection and accidental injury.ResultsSeven patients underwent femoral osseointegration and were followed up for a period of up to 3 years following surgery. The perioperative recovery was associated with significant escalation of analgesic requirements. Postoperative systemic inflammatory response syndrome was identified in six patients, with wound infection persisting in some cases into the rehabilitation phase. Three patients suffered femoral fractures following accidental injuries secondary to increased mobilisation following surgery.ConclusionsSuccessful surgical outcomes were achieved in a difficult patient cohort disadvantaged by previously restricted functional recovery from complex injuries. The importance of supporting the operative and recovery phases with a multidisciplinary pain service is emphasised. We offer this data and the lessons learnt to assist clinicians contemplating the establishment and service development of osseointegration services.

Abstract
Percutaneous approaches have become routine in transcatheter aortic valve replacement (TAVR). Despite numerous advantages, vascular complications associated with percutaneous access can occur during and after TAVR, and increase morbidity and mortality significantly. Effective management of potentially catastrophic vascular complications often requires prompt recognition, diagnosis, and management by multidisciplinary teams.

Abstract
A methodology has been demonstrated to consolidate Ti-6Al-4V powder without taking it to the liquid state by novel combination of the electron beam melting additive manufacture and hot isostatic pressing processes. This results in improved static mechanical properties (both strength and yield) in comparison to standard EBM processed material. In addition, the ability to generate microstructurally graded components has been demonstrated by generating a component with a significant change in both microstructure and mechanical properties. This is revealed by the use of electron backscattered diffraction and micro hardness testing to produce maps showing a clear distinction between materials consolidated in different ways. The variation in microstructure and mechanical properties is attributed to the different thermal history experienced by the material at different locations. In particular, it is found that the rapid cooling experienced during EBM leads to a typical fine α lath structure, whereas a more equiaxed α grains generated by diffusion is found in HIP consolidated powder.

Abstract
Transcatheter Aortic Valve Replacement (TAVR) has evolved as a strategy for managing aortic stenosis in a growing proportion of patients considered at high or intermediate surgical risk. Though early data has demonstrated excellent durability and life span of transcatheter valves up to five years, there is an absence of case based studies in the literature regarding transcatheter valve failure after TAVR, and outcomes of subsequent redo TAVR Valve-in-Valve (VIV) procedures. We report here a successful case of emergent, catheter-based treatment for severe, highly symptomatic valve in valve restenosis of a 5 year old Sapien valve.

Abstract
BACKGROUND Transcatheter mitral valve-in-valve (TMVIV) or valve-in-ring (TMVIR) replacement has shown early promise in patients deemed poor surgical candidates as a less invasive alternative to conventional reoperative mitral valve (MV) replacement. OBJECTIVE This retrospective, single-center study reviewed the procedural outcomes of all TMVIV and TMVIR procedures between 2013-2018 at a large tertiary referral center serving the southeastern United States. An analysis of patient safety measures was also performed, with a retrospective assessment of relative procedural safety that included preoperative risk stratification and postoperative mortality predictors, operative time, average blood loss, length of hospital stay, and readmission rates. METHODS This study included 24 patients with severe MV disease and medical comorbidities who were considered too high risk for conventional MV replacement. All patients underwent TMVIV or TMVIR with Edwards Sapien XT or S3 transcatheter valves (Edwards Lifesciences). A secure database of patient demographics, preoperative risk assessment, and procedural data was created and included technical success rates, blood loss, operative time, and intraoperative and immediate postoperative complications. Subsequent follow-up of patient outcomes reported here include those collected at 30 days, 180 days, and 1 year. RESULTS Of the 24 patients in our study, 16 received TMVIV and 8 received TMVIR implantation. Each procedure was performed successfully under general anesthesia via transseptal approach (n = 17) or transapical approach (n = 7), with only 1 patient (8.2%) requiring late operative reintervention 252 days post op. Average procedural time was 76 min and average blood loss was <75 mL, with 20/24 patients (83%) successfully extubated on postoperative day 0. Length of Intensive Care Unit stay was 1.7 ± 1.4 days and length of total inpatient stay was 2.8 ± 1.8 days. Echocardiograms were collected immediately post op, at 30 days, at 180 days, and subsequently at yearly intervals; follow-up demonstrated excellent prosthetic valve function with low transvalvular gradients, and no evidence of valve embolization or thrombosis. In patients with follow-up data available at 1 year (n = 13), there were no readmissions at 30 days or 180 days, and only 1 admission (8.3%) during the first postoperative year for symptoms related to congestive heart failure (CHF). CONCLUSION TMVIV and TMVIR can be safe and effective in a patient population considered at prohibitive risk for conventional surgery. These procedures can be performed efficiently in a hybrid operating room, with relatively short procedural times and high rates of early extubation. Procedural complications, mortality, and readmission rates for CHF at 30 days, 180 days, and 1 year were very low in this high-risk cohort.

Abstract
The Defence Medical Services (DMS) of the United Kingdom (UK) assumed command of the Role 3 Medical Treatment Facility field hospital during Operation HERRICK in Afghanistan from April 2006 until the final drawdown in November 2014. The signature injury sustained by coalition personnel during this period was traumatic amputation from improvised explosive devices. Many patients who had suffered extensive tissue damage experienced both nociceptive and neuropathic pain (NeuP). This presented as a heterogeneous collection of symptoms that are resistant to treatment. This paper discusses the relationship of NeuP in the context of ballistic injury, drawing in particular on clinical experience from the UK mission to Afghanistan, Operation HERRICK. The role of this paper is to describe the difficulties of assessment, treatment and research of NeuP and make recommendations for future progress within the DMS.

Abstract
The UK Defence Medical Service's Pre-Hospital Emergency Care (PHEC) capability includes rapid-deployment Medical Emergency Response Teams (MERTs) comprising tri-service trauma consultants, paramedics and specialised nurses, all of whom are qualified to administer emergency care under extreme conditions to improve the survival prospects of combat casualties. The pre-deployment training of MERT personnel is designed to foster individual knowledge, skills and abilities in PHEC and in small team performance and cohesion in 'mission-specific' contexts. Until now, the provision of airborne pre-deployment MERT training had been dependent on either the availability of an operational aircraft (eg, the CH-47 Chinook helicopter) or access to one of only two ground-based facsimiles of the Chinook's rear cargo/passenger cabin. Although MERT training has high priority, there will always be competition with other military taskings for access to helicopter assets (and for other platforms in other branches of the Armed Forces). This paper describes the development of an inexpensive, reconfigurable and transportable MERT training concept based on 'mixed reality' technologies-in effect the 'blending' of real-world objects of training relevance with virtual reality reconstructions of operational contexts.

Abstract
Primary blast lung injury frequently complicates military conflict and terrorist attacks on civilian populations. The fact that it occurs in areas of conflict or unpredictable mass casualty events makes clinical study in human casualties implausible. Research in this field is therefore reliant on the use of some form of biological or non-biological surrogate model. This article briefly reviews the modelling work undertaken in this field until now and describes the rationale behind the generation of an in silico physiological model.

Abstract
OBJECTIVE To (i) correlate B-mode ocular ultrasound (US) and computed tomography (CT) (prospective pilot study), (ii) establish a reliable method to measure the normal canine eye using CT, (iii) establish a reference guide for some dog breeds, (iv) compare eye size between different breeds and breed groups, and (v) investigate the correlation between eye dimensions and body weight, gender, and skull type (retrospective study). PROCEDURE B-mode US and CT were performed on ten sheep cadaveric eyes. CT biometry involved 100 adult pure-bred dogs with nonocular and nonorbital disease, representing eleven breeds. Eye length, width, and height were each measured in two of three planes (horizontal, sagittal, and equatorial). RESULTS B-mode US and CT measurements of sheep cadaveric eyes correlated well (0.70-0.71). The shape of the canine eye was found to be akin to an oblate spheroid (a flattened sphere). A reference guide was established for eleven breeds. Eyes of large breed dogs were significantly larger than those of medium and small breed dogs (P < 0.01), and eyes of medium breed dogs were significantly larger than those of small breed dogs (P < 0.01). Eye size correlated with body weight (0.74-0.82) but not gender or skull type. CONCLUSIONS Computed tomography is a suitable method for biometry of the canine eye, and a reference guide was established for eleven breeds. Eye size correlated with breed size and body weight. Because correlation between B-mode US and CT was shown, the obtained values can be applied in the clinical setting, for example, for the diagnosis of microphthalmos and buphthalmos.
