Abstract
Background Postoperative delirium (POD) is a frequently observed complication after transcatheter aortic valve replacement (TAVR). The effects of intraoperative hypotension (IOH) on POD occurrence are currently unclear. Methods A retrospective observational cohort study of patients who underwent TAVR was conducted. We predefined IOH as area under the threshold (AUT) of five mean arterial blood pressures (MBP), varying from <100 to <60 mmHg. The AUT consisted of the combination of duration and depth under the MBP thresholds, expressed in mmHg*min. All MBP AUTs were computed based on the complete procedure, independent of procedural phase or duration. Results This cohort included 675 patients who underwent TAVR under general anesthesia (n = 128, 19%) or procedural sedation (n = 547, 81%). Delirium occurred mostly during the first 2 days after TAVR, and was observed in n = 93 (14%) cases. Furthermore, 674, 672, 663, 630, and 518 patients had at least 1 min intraoperative MBP <100, <90, <80, <70, and <60 mmHg, respectively. Patients who developed POD had higher AUT based on all five MBP thresholds during TAVR. The penalized adjusted odds ratio varied between 1.08 (99% confidence interval [CI] 0.74–1.56) for the AUT based on MBP < 100 mmHg and OR 1.06 (99% CI 0.88–1.28) for the AUT based on MBP < 60 mmHg. Conclusions Intraoperative hypotension is frequently observed during TAVR, but not independently associated with POD after TAVR. Other potential factors than intraoperative hypotension may explain the occurrence of delirium after TAVR.

[PMID: 34416227 DOI: 10.1016/j.athoracsur.2021.07.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 06/11/2021] [Accepted: 07/08/2021] [Indexed: 11/01/2022]
Abstract
BACKGROUND Differences in left ventricular mass regression (LVMR) between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) have not been studied. We present clinical and echocardiographic data from veterans who underwent TAVR and SAVR, evaluating the degree of LVMR and its association with survival. METHODS We retrospectively reviewed TAVR (n = 194) and SAVR (n = 365) procedures performed in veterans from 2011 to 2019. After 1:1 propensity matching, we evaluated mortality and secondary outcomes. Echocardiographic data (median follow-up 957 days, interquartile range 483-1652 days) were used to evaluate LVMR, its association with survival, and predictors of LVMR. RESULTS There was no difference between SAVR and TAVR patients in mortality (for up to 8 years), stroke at 30 days, myocardial infarction, renal failure, prolonged ventilation, reoperation, or structural valve deterioration. SAVR patients (67.3% [101 of 150]) were more likely to have LVMR than TAVR patients (55.7% [44 of 79], P = .11). The magnitude of LVMR was greater for the SAVR patients (median, -23.3%) than for the TAVR patients (median, -17.8%, P = .062). SAVR patients with LVMR had a survival advantage over SAVR patients without LVMR (P = .016). However, LVMR was not associated with greater survival in TAVR patients (P = .248). CONCLUSIONS SAVR patients were more likely to have LVMR and had a greater magnitude of LVMR than TAVR patients. LVMR was associated with better survival in SAVR patients, but not in TAVR patients.

J Stroke Cerebrovasc Dis 2021; 30:105912. [PMID: 34130105 DOI: 10.1016/j.jstrokecerebrovasdis.2021.105912] [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: 02/02/2021] [Revised: 05/05/2021] [Accepted: 05/23/2021] [Indexed: 10/21/2022] Open
Abstract
BACKGROUND/OBJECTIVE While postoperative stroke is a known complication of Transcatheter Aortic Valve Implantation (TAVI), predictors of early stroke occurrence have not been specifically reviewed. The objective of this study was to estimate the predictors and incidence of stroke during the first 30 days post-TAVI. METHODS A cohort of 506 consecutive patients having undergone TAVI between January 2017 and June 2019 was extracted from a prospective database. Preoperative, intraoperative and postoperative characteristics were analyzed by univariate analysis followed by logistic regression to find predictors of the occurrence of stroke or death within the first 30 days after the procedure. RESULTS Incidence of stroke within 30 days post-TAVI was 4.9%, [CI 95% 3.3-7.2], i.e., 25 strokes. Four out of the 25 patients (16%) with a stroke died within 30 days post-TAVI. After logistic regression analysis, the predictors of early stroke related to TAVI were: CHA2Ds2VASc score ≥ 5 (odds ratio [OR] 2.62; 95% CI: 1.06-6.49; p = .037), supra-aortic access vs. femoral access (OR: 9.00, 95%CI: 2.95-27.44; p = .001) and introduction post-TAVI of a single vs. two or three antithrombotic agents (OR: 5.13; CI 95%: 1.99 to 13.19; p = .001). Over the 30-day period, bleeding occurred in 28 patients (5.5%), in 25 of whom, it was associated with femoral or iliac artery access injury. Anti-thrombotic regimen was not associated with bleeding; two patients out of 48 (4.1%) bled with a single anti-thrombotic regimen vs. 26 patients out of 458 (5.6%) with a dual or triple anti-thrombotic regimen (p = 0.94). The overall 30-day mortality rate was 3.9%, [95% CI 2.5-6.0]. Patients with a single post-TAVI antithrombotic agent (OR: 44.07 [CI 95% 13.45-144.39]; p < .0001) and patients with previous coronary artery bypass surgery or coronary artery stenting (OR: 6.16, [CI 95% 1.99-21.29]; p = .002) were at significantly higher risk of death within the 30-day period. CONCLUSION In this large-scale single-center retrospective study, a single post-TAVI antithrombotic regimen independently predicted occurrence of early stroke or death. Dual or triple antithrombotic regimen was not associated with a higher risk of bleeding and should be considered as an option in patients undergoing TAVI.

Abstract
Acute coronary artery obstruction is a rare but life-threatening complication of transcatheter aortic valve implantation. In patients at risk of coronary artery obstruction, pre-emptive coronary artery protection with a coronary wire, balloon or stent provides a bailout treatment option. The authors describe the steps involved in performing chimney stenting and summarise the short- and long-term outcome data associated with this technique.

Abstract
Aortic valve disease is one of the most common valvular heart diseases in the cardiovascular category. Surgical replacement of the diseased aortic valve remains the definitive intervention for most diseases. There is a clear consensus that in young patients who require aortic valve replacement, a mechanical prosthesis is the preferred choice due to its durable prosthesis without fear of wear and tear over time. However, this comes at the expense of increased risk of bleeding and thromboembolic events; in addition, there is a lack of strict evidence in using bioprosthesis in patients younger than 50 years. The objective of this review article is to assess the current evidence behind using bioprosthetic aortic valve in this young cohort.

Abstract
BACKGROUND The emergence of catheter-based techniques questioned existing treatment strategies for patients with aortic stenosis. The increasing effectiveness of transcatheter aortic valve implantation therapies justifies a renewed evaluation of the results in terms of survival rate as well as the quality of life (QoL) after surgical aortic valve replacement (SAVR) in the elderly. The aim of this study is the assessment of QoL in octogenarians undergoing isolated SAVR. METHODS A retrospective observational and descriptive study between January 2015 and January 2018, was conducted. Eighty-four Caucasians patients over 80 years of age undergoing aortic valve replacement in a single unit were, finally, followed-up. The patients' medical records were reviewed and QoL after a median 22-month follow-up time was evaluated by administering the EQ-5D questionnaire on the telephone. RESULTS Mean European System for Cardiac Operative Risk Evaluation II was 2.1%. The 30-day mortality was 0% and the 1-year mortality was 3.6%. On the assessment of QoL within mean follow-up time of 22 months, performed in 81 patients (survivors), a remarkable improvement was recorded in 76.5% of patients (62 patients), while 12.3% (10 patients) reported aggravation of their health status and 11.1% (9 patients) had no change. CONCLUSIONS Mortality rates after SAVR can be kept at very low levels, especially in experienced high-volume centers, even in the elderly. Furthermore, it must be pointed out that the majority of these patients achieve a good functional status and a satisfactory QoL after the operation. Therefore, SAVR should not be withheld on the grounds of age alone.

Abstract
Transcatheter aortic valve implantation (TAVI) has become the standard treatment for advanced age and high risk patients with severe aortic stenosis. The incidence of life-threatening complications during TAVI has significantly decreased over the last decade due to advanced current surgical experience. However, there is a risk of perioperative life-threatening complications which can require emergency hemodynamic support. Veno-arterial extracorporeal membrane oxygenation (ECMO) may represent an effective strategy for immediate hemodynamic stabilization until further treatment of the underlying complication. It is presented case report of TAVI under ECMO performed at the Kemerovo Research Institute for Complex Issues of Cardiovascular Diseases. Emergency ECMO represents a feasible strategy for stabilization until further treatment of life-threatening complications during TAVI.

Abstract
Background Acute kidney injury (AKI) is a common complication of aortic valve replacement. However, comparative on the incidence of (AKI) following transcatheter (TAVR) versus surgical valve replacement (SAVR) is sparse. Methods We performed a meta-analysis of the randomized controlled trials (RCT) and propensity-matched observational studies comparing (A) incidence of AKI and (B) incidence of dialysis-requiring AKI at 30 days after TAVR and SAVR. Results Twenty-six studies (20 propensity-matched studies; 6 RCTs) including 19,954 patients were analyzed. The incidence of AKI was lower after TAVR than after SAVR (7.1% vs. 12.1%, OR 0.52; 95%CI, 0.39-0.68; p<0.001, I2=57%), but the incidence of dialysis-requiring AKI was similar (2.8% vs. 4.1%, OR 0.78; 95%CI, 0.49-1.25; p=0.31, I2=70%). Similar results were observed in a sensitivity analysis including RCTs only for both AKI ([5 RCTs; 5,418 patients], 2.0% vs. 5.0%, OR 0.39; 95%CI, 0.28-0.53; p<0.001, I2=0%), and dialysis-requiring AKI ([2 RCTs; 769 patients]; 2.9% vs. 2.6%, OR 1.1; 95%CI, 0.47-2.58; p=0.83, I2=0%). However, in studies including low-intermediate risk patients only, TAVR was associated with lower incidence of AKI ([10 studies; 6,510 patients], 7.6% vs. 12.4%, OR 0.55, 95%CI 0.39-0.77, p<0.001, I2=57%), and dialysis-requiring AKI, ([10 studies; 12,034 patients], 2.0% vs. 3.6%, OR 0.57, 95%CI 0.38-0.85, p=0.005, I2=23%). Conclusions TAVR is associated with better renal outcomes at 30 days in comparison with SAVR, especially in patients at low-intermediate surgical risk. Further studies are needed to assess the impact of AKI on long-term outcomes of patients undergoing TAVR and SAVR.

Abstract
Due to the absence of annular calcification for device anchoring, it is presumed that transcatheter aortic valve replacement (TAVR) is not suitable for the treatment of native aortic valve regurgitation (NAVR) resulting in very limited data and experience concerning its safety and efficacy. We sought to review published data on the safety and efficacy of TAVR in high-risk patients with NAVR. Studies including case reports, case series and original articles published between 2002 and 2016 on TAVR in patients with NAVR were identified with a systematic electronic search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Only studies reporting data on demographic and procedural characteristics, management and follow up outcomes were analyzed. A total of 30 publications describing 182 patients were identified. Most patients (54%) were men, with a mean age of 70.1±2.6 years, mean logistic European System for Cardiac Operative Risk Evaluation score (EuroSCORE) of 21.8%±4.5% and mean Society of Thoracic Surgeons (STS) score of 8%±1.8% for mortality. The majority (87%) of patients had severe NAVR with no valvular calcification. TAVR was mostly performed through the femoral (58.8%) and apical (33.1%) approach. Device success, defined by VARC-2, was achieved in 86.3% of our study population. A second valve was required in 17 patients (9.3%) during the index procedure for residual aortic regurgitation or malposition. Post-procedure aortic regurgitation of grade 1 or less was present in 80 patients (81%). Pacemaker implantation was required post procedure in 17 patients (9.3%). The 30-day and 1-year mortality was 11.9% and 16.2%, respectively. TAVR is associated with favorable pacemaker implantation and 1-year mortality rates with a high 30-day mortality among selected patients with NAVR.

Abstract
BACKGROUND The Society of Thoracic Surgeons (STS) surveyed cardiothoracic surgeon participants in its Adult Cardiac Surgery Database (ACSD) to learn the extent of surgeon involvement in transcatheter aortic valve replacement (TAVR) procedures. METHODS An electronic survey was delivered to 2,594 surgeons in June 2016. When the survey closed 2 weeks later, 487 completed surveys had been submitted for a response rate of 18.8%. RESULTS Among the 487 participants in the ACSD who responded to the survey, 410 (84.2%) reported that TAVR was performed at their institutions. Approximately three-quarters reported that they performed TAVR procedures as part of a heart team (77.5%; 313 of 404), cardiologists and cardiothoracic surgeons were jointly responsible for TAVR referrals (83.7%; 339 of 405), and TAVR programs were administered either jointly by the cardiology and cardiac surgery departments or exclusively by the cardiac surgery department (73.3%; 297 of 405). A majority were involved in the pre-, intra-, and postoperative care of patients undergoing TAVR, with 91.4% (370 of 405) reporting participation in multidisciplinary meetings, at least 50% regularly performing technical aspects in 10 of 11 conduct of operation categories, and 86.6% (266 of 307) caring for patients undergoing TAVR after the procedure. CONCLUSIONS Cardiac surgeons in the United States are active participants in the management of patients with aortic stenosis as part of the heart team. The STS survey found that not only were they actively involved in the treatment decision-making process but they also played a significant role in the valve procedure, including deployment and postprocedural care. The heart team model continues to evolve and should be expanded into other areas of structural heart disease.

Abstract
As structural heart disease interventions continue to evolve to a sophisticated level, accurate and reliable imaging is required for pre-procedural selection of cases, intra-procedural guidance, post-procedural evaluation, and long-term follow-up of patients. Traditionally, cardiovascular procedures in the catheterization laboratory are guided by fluoroscopy and angiography. Advances in echocardiography can overcome most limitations of conventional imaging modalities and provide successful completion of each step of any catheter-based treatment. Echocardiography's unique characteristics rendered it the ideal technique for percutaneous catheter-based procedures. The purpose of this review is to demonstrate the use of the most common and up-to-date echocardiographic techniques in recent non-coronary percutaneous interventional procedures, underlining its inevitable and growing role, as well as illustrating areas of weakness and limitations, and to provide future perspectives.

Abstract
BACKGROUND In patients with symptomatic severe aortic stenosis, advanced age is often a reason for a transcatheter rather than surgical aortic valve replacement. In this pre-transcatheter cohort we had the unique opportunity to study outcomes after surgical aortic valve replacement for severe aortic stenosis in patients who might currently be triaged to a percutaneous approach. METHODS In a prospective single-center cohort study we compared the incidence of peri-operative complications, mortality, and health-related quality of life in octogenarians versus patients aged <80 years. The quality of life was measured using the SF-36 questionnaire and expressed as a physical and mental component score (PCS and MCS respectively); a score of 50 equals the average score in the age-matched general population. The association between age and the component scores at one-year follow-up was studied with the use of linear regression, corrected for a set of confounding variables. RESULTS We included 762 patients, of whom 21.4 % was aged >80 and 49.0 % underwent concomitant revascularization. In octogenarians, the incidence of post-operative delirium was 11.0 %, which was higher than in patients aged below 80 (6.2 %, p = 0.034); the operative mortality (1.9 % vs. 2.9 %; p = 0.59) and long-term survival were not different however (log-rank p = 0.75). In octogenarians, the quality of life was impaired 30-days after surgery (PCS 45.01, p < 0.001; MCS 48.21, p = 0.04), which improved towards or above normal values at one-year follow-up (PCS: 49.92, p = 0.67, MCS: 52.55, p < 0.001). After correction for confounding, age was not significantly associated with the one-year PCS (β 0.08 per year, p = 0.34) or MCS (β 0.08 per year, p = 0.32). CONCLUSIONS This pre-transcatheter study showed that surgical aortic valve replacement in octogenarians could be performed with very low mortality, and with a relevant and significant increase of the quality of life towards normal values. Also, age was not associated with a lower PCS or MCS one-year after surgery.

Abstract
BACKGROUND The aim of this study was to analyze the angle between the left ventricular (LV) long axis and the LV outflow tract (αLV-LVOT) on cardiac computed tomography and to describe its effect on the occurrence of paravalvular leakage (PL), fluoroscopy time, and postoperative creatine kinase-MB levels in transapical transcatheter aortic valve replacement (TA-TAVR). METHODS High-risk patients with severe aortic stenosis scheduled for TA-TAVR using an Edwards SAPIEN (Edwards Lifesciences, Irvine, CA) prosthesis were retrospectively included. The αLV-LVOT was measured during systole and diastole as far as retrospectively gated data sets were available. The αLV-LVOT was correlated with the occurrence of PL, total fluoroscopy time, and postoperative creatine kinase-MB levels. Interobserver variability was assessed in all cases. RESULTS The study included 81 patients (57 women [70.4%], 24 men [29.6%]) with an average age of 81.9±5.8 years. The mean αLV-LVOTs were 61.8±9.9 degrees during systole and 61.1±10.0 degrees during diastole. There was a minimal, nonsignificant change in the αLV-LVOT between systole and diastole of 0.2±4.1 degrees (p=0.7). PL was found in 39 patients: grade 0 in 42 (51.9%), grade I in 30 (37.0%), and grade II in 9 (11.1%). Patients with a clinically significant PL (grade≥II) showed a significantly greater mean αLV-LVOT than patients with grade I or without PL (mean difference, 13.8±3.2 degrees; p<0.001). No significant correlation was found between the αLV-LVOT and total fluoroscopy time (r=-0.17, p=0.16) and postoperative creatine kinase-MB levels (r=-0.1, p=0.44). CONCLUSIONS During TA-TAVR, greater αLV-LVOTs were associated with significantly higher grades of PL. Thus, the αLV-LVOT might influence the selection of the transapical implantation path and could have a significant effect on designs for future stents or novel delivery devices.

Abstract
AIMS Transcatheter aortic valve implantation (TAVI) is increasingly considered as a viable alternative to conventional aortic valve replacement (AVR) in high-risk patients. Long-term results, however, are still scarce and medical community hesitates in enlarging indications to lower-risk patients. Moreover, available devices are expensive and a strict potential candidate selection is necessary. METHODS From April 2008 to August 2012, a total of 212 patients, originally referred for percutaneous treatment, were thoroughly evaluated by the aortic team of our department in order to choose the optimal procedure. Of them, 55 patients (35 women; 20 men) were considered as still acceptable candidates for conventional AVR. RESULTS Mean age was 80.7 ± 4.7 years; mean additive and logistic Euroscore I were 9.7 ± 1.8 and 17.8 ± 9.5%, respectively. Mean Euroscore II was 7.9 ± 5.5%. Mean New York Heart Association class was 2.9 ± 0.5. The majority of patients (87.2%) presented a geriatric frailty score of 0-1. Four patients showed a heavily calcified ascending aorta, and five patients (9%) underwent reoperations. Hospital mortality was 10.9% (six patients). Mean follow-up was 535.9 ± 407.4 days (range: 6-1365 days). Six other patients died during this period for a mean survival of 74.4 ± 6.9% at 2 years. Mean New York Heart Association class at 1 year was 1.25 ± 0.5 (P < 0.01 vs. preoperative value). CONCLUSION AVR should be indicated with caution in high-risk patients originally referred for TAVI. Despite medium-term results being good, with excellent functional status, hospital mortality is not negligible.

Abstract
This paper describes "how to" examine cardiac valves with computed tomography, the normal, diseased valves, and prosthetic valves. A review of current scientific literature is provided. Firstly, technical basics, "how to" perform and optimize a multislice CT scan and "how to" interpret valves on CT images are outlined. Then, diagnostic imaging of the entire spectrum of specific valvular disease by CT, including prosthetic heart valves, is highlighted. The last part gives a guide "how to" use CT for planning of transcatheter aortic valve implantation (TAVI), an emerging effective treatment option for patients with severe aortic stenosis. A special focus is placed on clinical applications of cardiac CT in the context of valvular disease.

Abstract
Transcatheter valve implantation (TAVI) is becoming a routine procedure to treat severe symptomatic aortic stenosis. It is associated with complications different from those of conventional aortic valve surgery. We describe an 80-year old man who developed an apical left ventricular (LV) false aneurysm 3 months after transapical TAVI (TA-TAVI) complicated postoperatively by a surgical site infection (SSI). Three months earlier, an Edwards Sapien bioprosthesis no. 29 had been successfully inserted transapically because of severe comorbidities and a very large aortic annulus. His postoperative course was complicated by acute respiratory failure, gastrointestinal bleeding and a surgical site infection of the thoracic incision; Escherichia coli and Klebsiella pneumonia were isolated. After surgical debridement drainage and prolonged antibiotic therapy, the wound healed correctly. His emergency chest computed tomography upon readmission for the acute onset of a beating tumefaction at the TA-TAVI site showed a false aneurysm of the LV apex. The apex was closed directly during emergency surgery. The postoperative course was uneventful. Surgical site infection after TA-TAVI, its frequency, treatment and potential role as an underlying cause of this severe complication are discussed.

Abstract
Present prosthetic heart valves, while hemodynamically effective, remain limited by progressive structural deterioration of tissue valves or the burden of chronic anticoagulation for mechanical valves. An idealized valve prosthesis would eliminate these limitations. Polymeric heart valves (PHVs), fabricated from advanced polymeric materials, offer the potential of durability and hemocompatibility. Unfortunately, the clinical realization of PHVs to date has been hampered by findings of in vivo calcification, degradation and thrombosis. Here, the authors review the evolution of PHVs, evaluate the state of the art of this technology and propose a pathway towards clinical reality. In particular, the authors discuss the development of a novel aortic PHV that may be deployed via transcatheter implantation, as well as its optimization via device thrombogenicity emulation.

Abstract
Transcatheter aortic valve implantation (TAVI) has emerged as a highly effective minimally invasive treatment symptomatic for severe calcific aortic stenosis in patients at high or prohibitive surgical risk. The success of TAVI has been determined by a number of factors, but in particular by appropriate patient selection. Appropriate patient selection involves identifying patients with the potential to benefit most from TAVI and individualizing the bioprosthesis type and size, and the vascular access site for each case. We present herein, our critical appraisal on patient selection for TAVI: an interventional cardiology perspective.

Abstract
BACKGROUND Transcatheter aortic valve implantation (TAVI) through a transapical approach (TAAVI) for severe aortic stenosis becomes the procedure of choice in cases where patients have peripheral artery disease and unfeasible access due to excessive atherosclerotic disease of the iliofemoral vessels and aorta. The present systematic review aimed to assess the safety, success rate, clinical outcomes, hemodynamic outcomes, and survival benefits of TAAVI. METHODS Electronic searches were performed in 6 databases from January 2000 to February 2012. The primary end points included feasibility and safety. Other end points included echocardiographic findings, functional class improvement, and survival. RESULTS After applying the inclusion and exclusion criteria, 48 out of 154 shortlisted potentially relevant articles were selected for assessment. Of these, 26 studies from 24 centers including total number of 2,807 patients were included for appraisal and data extraction. The current evidence on TAAVI for aortic stenosis is limited to observational studies. Successful TAAVI implantation occurred in >90% of patients. On average, the procedure took between 64 to 154 minutes to complete. The incidence of major adverse events included 30-day mortality (4.7-20.8%); cerebrovascular accident (0-16.3%); major tachyarrhythmia (0-48.8%); bradyarrhythmia requiring permanent pacemaker insertion (0-18.7%); cardiac tamponade (0-11%); major bleeding (1-17%); myocardial infarction (0-6%); aortic dissection/rupture (0-5%); moderate to severe paravalvular leak (0.7-24%); cardiopulmonary bypass support (0-15%); conversion to surgery (0-9.5%); and valve-in-valve implantation (0.6-8%). Mean aortic valve area improved from 0.4-0.7 cm(2) before TAAVI to 1.4-2.1 cm(2) after TAAVI. The peak pressure gradient across the aortic valve decreased from >70 mmHg to <20 mmHg after TAAVI. One-year survival ranged from 49.3% to 82% and the 3-year survival was 58% in 2 series. CONCLUSIONS TAAVI appears to be feasible with a reasonable safety and efficacy portfolio. Randomised controlled trials are required to compare transapical vs. transfemoral TAVI when both techniques are equally feasible.

Abstract
Aortic stenosis affects many people worldwide with a significant impact on morbidity and mortality with uncorrected, symptomatic aortic valve stenosis carrying mortality of 50% at one year. Degenerative calcific pathology, the most common cause of aortic stenosis, increases in prevalence with age; estimated prevalence of 5% in individuals over 75 years of age. Despite the malignant prognosis without valve replacement, many patients are not offered surgery due to advanced age and co-existing medical conditions; reported to be a third of symptomatic patients. In the last several years, transcatheter aortic valve replacement has emerged as an alternative treatment in patients with high or prohibitive open surgical risk. The PARTNER cohort B data, employing the Sapien valve, demonstrated a 20% absolute mortality benefit at one year compared with medical therapy. In this review, we provide an update of this technology and discuss patient selection, procedural planning, complications, and look toward the future of transcatheter heart valves in the treatment of aortic stenosis.

Abstract
OBJECTIVES The aim of the current Valvular Academic Research Consortium (VARC)-2 initiative was to revisit the selection and definitions of transcatheter aortic valve implantation (TAVI)- clinical endpoints to make them more suitable to the present and future needs of clinical trials. In addition, this document is intended to expand understanding of patient risk stratification and case selection. BACKGROUND A recent study confirmed that VARC definitions have already been incorporated into clinical and research practice and represent a new standard for consistency in reporting clinical outcomes of patients with symptomatic severe aortic stenosis (AS) undergoing TAVI. However, as the clinical experience with this technology has matured and expanded, certain definitions have become unsuitable or ambiguous. METHODS AND RESULTS Two in-person meetings (held in September 2011 in Washington, DC, USA, and in February 2012 in Rotterdam, The Netherlands) involving VARC study group members, independent experts (including surgeons, interventional and non-interventional cardiologists, imaging specialists, neurologists, geriatric specialists, and clinical trialists), the United States Food and Drug Administration (FDA), and industry representatives, provided much of the substantive discussion from which this VARC-2 consensus manuscript was derived. This document also provides an overview of risk assessment and patient stratification that needed to be considered for accurate patient inclusion in studies. Working groups were assigned to define the following clinical endpoints: mortality, stroke, myocardial infarction, bleeding, acute kidney injury, vascular complications, conduction disturbances & arrhythmias, and a miscellaneous category including relevant complications not previously categorized. Furthermore, comprehensive echocardiographic recommendations are provided for evaluation of prosthetic valve (dys)function. Definitions for quality of life assessments are also reported. These endpoints formed the basis for several recommended composite endpoints. CONCLUSIONS This VARC-2 document has provided further standardization of endpoint definitions for studies evaluating the use of TAVI, which will lead to improved comparability and interpretability of study results, supplying an increasingly growing body of evidence with respect to transcatheter aortic valve implantation and/or surgical aortic valve replacement. This initiative and document can furthermore be used as a model during current endeavors of applying definitions to other transcatheter valve therapies (for example, mitral valve repair).

Abstract
The Edwards SAPIEN transcatheter heart valve (THV) is approved for aortic stenosis patients considered inoperable because of high surgical risk. Based on the high-risk arm of the PARTNER trial, the Food and Drug Administration's Circulatory System Devices Panel reviewed an additional indication for use in high-risk, operable patients. Although several concerns were raised regarding safety, trial misconduct, and several subgroup analyses, most panel members agreed that the Edwards SAPIEN THV (Edwards Lifesciences LLC, Irvine, CA), when used in high-risk patients, is noninferior to surgical aortic valve replacement. The panel voted 11 to 0 (with 1 abstention) that the benefits of the Edwards SAPIEN THV do outweigh the risks for use in the indicated patient population. This summary aims to describe the discussions and recommendations made during the meeting. Based on the panel recommendation, the device was approved by the Food and Drug Administration.

Abstract
Little is known about transcatheter aortic valve implantation (TAVI) in patients with bicuspid aortic valve stenosis, which usually represents a contraindication. The aim of this study was to assess the feasibility and the results of TAVI in this patient subset. Of 316 high-risk patients with severe aortic stenosis who underwent TAVI from January 2009 to January 2012, 15 (5%) had documented bicuspid aortic valves. They were treated using a transarterial approach, using the Medtronic CoreValve system. Patients were aged 80 ± 10 years, in New York Heart Association functional classes III and IV. The mean aortic valve area was 0.8 ± 0.3 cm(2), and the mean gradient was 60 ± 19 mm Hg. The mean calcium score, calculated using multislice computed tomography, was 4,553 ± 1,872 arbitrary units. The procedure was successful in all but 1 patient. Major adverse events, according to Valvular Academic Research Consortium definitions, were encountered in 1 patient (death). The mean postimplantation prosthetic gradient was 11 ± 4 mm Hg, and ≤1+ periprosthetic leaks were observed in all but 2 patients. The mean prosthetic ellipticity index was 0.7 ± 0.2 at the level of the native annulus and 0.8 ± 0.2 at the level of the prosthetic leaflets. After a mean follow-up period of 8 ± 7 months, 1 patient had died from aortic dissection; there were no additional adverse events. All but 2 hospital survivors were in New York Heart Association class I or II. In conclusion, the present series suggests that transarterial Medtronic CoreValve implantation is feasible in selected patients with bicuspid aortic valve and may lead to short-term hemodynamic and clinical improvement.
