RESUMO

INTRODUCCIÓN: La estenosis aórtica (EAo) es la valvulopatía más frecuente en adultos mayores de 75 años, con una población estimada en Argentina de 2.011.511. Sin tratamiento quirúrgico o percutáneo, una vez iniciados los síntomas la sobrevida de estos pacientes se acorta drásticamente. Hasta hace unos años, la cirugía de reemplazo valvular aórtico (CRVAo) ha sido el tratamiento de elección, en aquellos pacientes que por sus condiciones clínicas podían afrontar este procedimiento. DESCRIPCIÓN DE LA TECNOLOGÍA: La implantación de la válvula aórtica transcatéter (TAVI) tiene como objetivo proporcionar una alternativa menos invasiva a la cirugía cardíaca abierta para tratar la EAo, evitando la necesidad de esternotomía y bypass ardiopulmonar. OBJETIVO: El objetivo del presente informe es evaluar la evidencia actualizada de la EFICACIA, la SEGURIDAD de la TAVI en el tratamiento de pacientes con estenosis aórtica severa sintomática. En pacientes de altísimo riesgo (inoperables) comparado con el tratamiento de sostén (farmacológico / valvuloplastia) y en pacientes de alto / intermedio / Bajo riesgo quirúrgico comparado con la Cirugía de Reemplazo Valvular aórtico (CRVAo).También se evaluará el impacto presupuestario, políticas de cobertura y los criterios para acreditación de centros especializados en la colocación de los TAVI. MÉTODOS: Se realizó una búsqueda bibliográfica en las principales bases de datos, en buscadores genéricos de internet, y financiadores de salud. Se dio prioridad a las Revisiones Sistemáticas (RS), evaluaciones de tecnologías sanitarias (ETS), evaluaciones económicas (EE), guías de práctica clínica (GPC), políticas de cobertura (PC) de diferentes sistemas de salud y ensayos clínicos aleatorizados (ECA). Se tomó como base el documento de ETS de Alfie V y col. RESULTADOS: Se decidió estratificar la búsqueda bibliográfica en subgrupos según el riesgo quirúrgico de los pacientes con estenosis aórtica severa, ya se interpretó que podría tener diferente impacto la tecnología analizada. Se incluyeron cinco Revisiones sistemáticas / Meta-análisis, tres Guías Practicas Clínicas, tres Consensos. En pacientes con EAo severa inoperables, evidencia de moderada calidad, sugiere que el tratamiento con TAVI comparado con tratamiento de sostén, presenta mejor eficacia (reduzca la mortalidad por todas las causas y mortalidad cardíaca con un seguimiento a 5 años). Presenta un perfil de seguridad con el cual es probable que reduzca la rehospitalización pero aumente las complicaciones vasculares mayores, y que podría no presentar diferencias en los desenlaces de infarto agudo de miocardio, accidente cerebro vascular, insuficiencia renal, colocación de marcapasos permanente, sangrado mayor y endocarditis. No se encontró evidencia sobre función ventricular, durabilidad de la válvula. El impacto económico de la tecnología en esta población se consideró no favorable. El impacto en la equidad se consideró como negativo y en la salud pública se consideró probablemente negativo. En pacientes con EAo severa de alto riesgo quirúrgico, evidencia de baja calidad, sugiere que la tecnología no logró demostrar diferencias estadísticamente significativas en los puntos críticos (mortalidad por todas las causas y cardiovascular) con un seguimiento a 5 años, presenta un perfil de seguridad que podría reducir los desenlaces de hemorragias graves, desajuste protésico severo, insuficiencia renal aguda pero podría aumentar la regurgitación aórtica moderada-severa, además podría no presentar diferencias en los desenlaces de accidente cerebro vascular, complicaciones vasculares mayores, infarto agudo de miocardio, colocación de marcapasos. No se encontró evidencia sobre función ventricular, durabilidad de la válvula, re-hospitalización, endocarditis. El impacto económico de la tecnología en esta población se consideró no favorable. El impacto en la equidad se consideró como negativo y en la salud pública se consideró probablemente negativo. En pacientes con EAo severa de intermedio riesgo, evidencia de baja calidad en el tratamiento TAVI comparado con la CRVAo, sugiere que la tecnología no logro demostrar diferencias estadísticamente significativas en los puntos críticos (mortalidad por todas las causas y cardiovascular, con un seguimiento mayor a 2 años). Presenta un perfil de seguridad que podría reducir los desenlaces de fibrilación auricular e insuficiencia renal aguda, pero podría aumentar las complicaciones vasculares y colocación de marcapaso permanente, además podría no presentar diferencias en los desenlaces de accidente cerebro vascular, complicaciones vasculares mayores, infarto agudo de miocardio, regurgitación aórtica severa. No se encontró evidencia sobre calidad de vida, clase funcional, función ventricular, durabilidad de la válvula, re-hospitalización, desajuste protésico y endocarditis. El impacto económico de la tecnología en esta población se consideró no favorable. El impacto en la equidad se consideró como negativo y en la salud pública se consideró probablemente negativo. En pacientes con EAo severa de bajo riesgo, evidencia de baja calidad sugiere que el tratamiento TAVI comparado con la CRVAo, sugiere que la tecnología no logro demostrar diferencias estadísticamente significativas en los puntos críticos (mortalidad por todas las causas), con un seguimiento 1 a 3 años. Presenta un perfil de seguridad que podría reducir los desenlaces de fibrilación auricular, insuficiencia renal aguda, pero podría aumentar las complicaciones vasculares y colocación de marcapaso permanente. No se encontró evidencia sobre calidad de vida, clase funcional, función ventricular, durabilidad de la válvula, re-hospitalización, desajuste protésico y endocarditis. El impacto económico de la tecnología en esta población se consideró no favorable. El impacto en la equidad se consideró como negativo y en la salud pública se consideró probablemente negativo. Al analizar lo que ocurre en otras regiones en Latinoamérica únicamente Chile acepta la cobertura del TAVI en pacientes inoperables por cirugía convencional, el resto de los países no informan acerca de su cobertura o no lo recomiendan como es el caso de Brasil. En EE.UU. Medicare y Medicaid acepta la cobertura de TAVI en pacientes de riesgo inoperables y alto, sin embargo, definen ciertos criterios como, la indicación de TAVI debe ser realizada por un Heart Team a su vez establece rigurosos parámetros de control donde establecen la complejidad que deben tener los centros habilitados y cuál es el mínimo volumen anual de un servicio para realizar TAVI con estos financiadores. Australia y Francia no lo recomiendan es uso de TAVI por el momento. En riesgo intermedio y bajo únicamente Anthem de EE.UU. recomienda su cobertura.

RESUMO

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the preferred treatment option for older patients with symptomatic severe aortic stenosis. Differences in the properties of available TAVR systems can affect clinical outcomes. Among patients undergoing TAVR, we compared the self-expanding ACURATE neo TAVR system with the balloon-expandable SAPIEN 3 TAVR system with regard to early safety and efficacy. METHODS: In this randomised non-inferiority trial, patients (aged ≥75 years) undergoing transfemoral TAVR for treatment of symptomatic severe aortic stenosis, and who were deemed to be at increased surgical risk, were recruited at 20 tertiary heart valve centres in Germany, the Netherlands, Switzerland, and the UK. Participants were randomly assigned (1:1) to receive treatment with the ACURATE neo or the SAPIEN 3 with a computer-based randomly permuted block scheme, stratified by study centre and Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) category. The primary composite safety and efficacy endpoint comprised all-cause death, any stroke, life-threatening or disabling bleeding, major vascular complications, coronary artery obstruction requiring intervention, acute kidney injury (stage 2 or 3), rehospitalisation for valve-related symptoms or congestive heart failure, valve-related dysfunction requiring repeat procedure, moderate or severe prosthetic valve regurgitation, or prosthetic valve stenosis within 30 days of the procedure. Endpoint assessors were masked to treatment allocation. Non-inferiority of ACURATE neo compared with SAPIEN 3 was assessed in the intention-to-treat population on the basis of a risk-difference margin of 7·7% for the primary composite endpoint, with a one-sided α of 0·05. This trial is registered with ClinicalTrials.gov (number NCT03011346) and is ongoing but not recruiting. FINDINGS: Between Feb 8, 2017, and Feb 2, 2019, up to 5132 patients were screened and 739 (mean age 82·8 years [SD 4·1]; median STS-PROM score 3·5% [IQR 2·6-5·0]) were enrolled. 30-day follow-up was available for 367 (99%) of 372 patients allocated to the ACURATE neo group, and 364 (99%) of 367 allocated to the SAPIEN 3 group. Within 30 days, the primary endpoint occurred in 87 (24%) patients in the ACURATE neo and in 60 (16%) in the SAPIEN 3 group; thus, non-inferiority of the ACURATE neo was not met (absolute risk difference 7·1% [upper 95% confidence limit 12·0%], p=0·42). Secondary analysis of the primary endpoint suggested superiority of the SAPIEN 3 device over the ACURATE neo device (95% CI for risk difference -1·3 to -12·9, p=0·0156). The ACURATE neo and SAPIEN 3 groups did not differ in incidence of all-cause death (nine patients [2%] vs three [1%]) and stroke (seven [2%] vs 11 [3%]); whereas acute kidney injury (11 [3%] vs three [1%]) and moderate or severe prosthetic aortic regurgitation (34 [9%] vs ten [3%]) were more common in the ACURATE neo group. INTERPRETATION: TAVR with the self-expanding ACURATE neo did not meet non-inferiority compared to the balloon-expandable SAPIEN 3 device in terms of early safety and clinical efficacy outcomes. An early composite safety and efficacy endpoint was useful in discriminating the performance of different TAVR systems. FUNDING: Boston Scientific (USA).

RESUMO

BACKGROUND: Despite the worldwide development of transcatheter aortic valve implantation (TAVI) over the last decade, strategies that take patient characteristics into account to guide the choice of transcatheter heart valve have not been evaluated. AIM: To evaluate the immediate results of TAVI using a tailored choice of balloon-expandable or self-expanding transcatheter heart valve, according to each patient's clinical and anatomical characteristics. METHODS: This single-centre observational study included all patients treated with TAVI from 2012 to 2017. The 30-day results were reported according to Valve Academic Research Consortium-2 criteria. A total of 502 patients were included (mean age, 81±9 years; 52% men; mean EuroSCORE II, 7.0±6.5%). Three main variables guided the choice of transcatheter heart valve: the anatomy of the iliofemoral arteries and of the aortic root, and the general condition of the patient. RESULTS: A SAPIEN™ balloon-expandable transcatheter heart valve was used in 275 patients (55%) and a CoreValve™ self-expanding transcatheter heart valve in 227 patients (45%). The approach was transfemoral in 427 patients (85%), and only 29 patients (6%) required transthoracic access. At 30-day follow-up, the rates of adverse events were as follows: mortality, 3.2%; stroke, 3.0%; major bleeding, 5.9%; and major vascular complications, 6.0%. Rates of complications at 30 days were similar in the SAPIEN™ and CoreValve™ groups, except for a higher rate of pacemaker implantation in the latter group (29.5% vs. 14.5%; P<0.001). CONCLUSION: The choice of balloon-expandable or self-expanding transcatheter heart valve tailored to the patient's clinical and anatomical characteristics allows for maximal use of the transfemoral approach, and is associated with low 30-day rates of major complications and mortality.

RESUMO

AIMS: The aim of this study was to evaluate the impact of a horizontal aorta (HA) on device success and short-term clinical outcomes of transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: We retrospectively assessed 547 consecutive patients treated with transfemoral second-generation non-balloon-expandable (NBE) (n=447) and balloon-expandable (BE) (n=100) TAVI for symptomatic severe aortic stenosis. Aortic angulation (AA) was evaluated with preprocedural computed tomography. Patients were dichotomised according to a previously established AA cut-point: HA group (AA ≥48°, n=230) and normal aorta (NA) group (AA <48°, n=317). Endpoints were considered according to the Valve Academic Research Consortium-2 definitions. Fluoroscopy time (32.8±16.4 vs 30.3±13.9 minutes, p=0.060) and radiation dose (kerma area product 120.8±99.7 vs 103.7±81.1 Gy·cm2, p=0.033) were higher in the HA group as compared to the NA group. No difference in device success was observed between patients with and without an HA (88.3% vs 88.0%, p=0.929). No differences in device success and 30-day outcomes were observed when comparing HA and NA patients, according to BE and NBE prostheses. CONCLUSIONS: The presence of an HA has no impact on device success and short-term clinical outcomes of TAVI with either second-generation NBE or BE devices.

RESUMO

The combination of aortic and mitral regurgitation is a typical example of a frequent yet understudied multiple valve disease scenario. The aetiology is often rheumatic or degenerative; less frequently it can be induced by drugs or radiation, or caused by infective endocarditis or congenital valvular lesions. Aortic regurgitation resulting in secondary mitral regurgitation is also not uncommon. There are limited data to guide the management of combined aortic and mitral regurgitation. Left ventricular dysfunction is frequent at initial presentation, and even more so postoperatively, suggesting that surgical management should not be delayed, particularly when symptoms occur or when there is evidence of even subtle left ventricular dysfunction. The decision to operate on one or both valves not only depends on the severity of each lesion, but also on several other factors, including age, co-morbidities and frailty, the increased operative risk of double valve surgery, the increased risk of long-term thrombotic and bleeding complications with multiple mechanical valves, the risk of leaving one valve unoperated and the probability of requiring redo surgery. The role of a multidisciplinary heart valve team is critical in this setting to optimize management and outcomes. The role of transcatheter approaches is currently limited, but technological advances will probably soon change the management paradigm.

RESUMO

The prevalence of combined severe aortic stenosis and abdominal aortic aneurysm is increasing with the aging of the population. Both conditions are associated with adverse outcome if not adequately managed. The choice of the optimal treatment of these patients is challenging and no clear recommendations are available. We report 2 cases of patients with concomitant severe symptomatic aortic stenosis and infrarenal abdominal aortic aneurysm successfully treated with combined transfemoral transcatheter aortic valve implantation (TAVI) and endovascular aortic aneurysm repair (EVAR). The reported cases demonstrate the versatility of transcatheter techniques and suggest that, in carefully selected patients, the combined procedure of TAVI plus EVAR, if performed by multidisciplinary expert operators, is safe and effective.

RESUMO

Aortic valve surgery in non-elderly patients represents a very challenging patient population. The younger the patient is at the point of aortic valve intervention, the longer their anticipated life expectancy will be, with longer exposure to valve-related complications and risk for re-operation. Although the latest international guidelines recommend aortic valve repair in patients with aortic valve insufficiency, what we see in the real world is that the vast majority of these aortic valves are replaced. However, current prosthetic valves has now been shown to lead to significant loss of life expectancy for non-elderly patients up to 50% for patients in their 40s undergoing mechanical aortic valve replacement. Bioprostheses carry an even worse long-term survival, with higher rates of re-intervention. The promise of trans-catheter valve-in-valve technology is accentuating the trend of bioprosthetic implantation in younger patients, without yet the appropriate evidence. In contrast, aortic valve repair has shown excellent outcomes in terms of quality of life, freedom from re-operation and freedom from major adverse valve-related events with similar life expectancy to general population as it is also found for the Ross procedure, the only available living valve substitute. We are at a time when the paradigm of aortic valve surgery needs to change for the better. To better serve our patients, we must acquire high quality real-world evidence from multiple centers globally - this is the vision of the AVIATOR registry and our common responsibility.

RESUMO

BACKGROUND: Access-site bleeding is a common complication of transfemoral transcatheter aortic valve implantation (TAVI). Percutaneous stent-graft implantation within the femoral artery may achieve hemostasis and avert the need for more invasive surgical vascular repair; however, failure to advance a guidewire antegradely via the injured vessel may preclude stent delivery. While retrograde stent-graft delivery from the distal vasculature may potentially enable percutaneous control of bleeding, this approach has not been reported. OBJECTIVES: To assess the feasibility of a retrograde approach for stent-graft implantation in the treatment of access-site bleeding following transfemoral TAVI. METHODS: A prospective TAVI registry was analyzed. Of 349 patients who underwent TAVI, transfemoral access was used in 332 (95%). Access-site injury requiring stent-graft implantation occurred in 56 (17%). In four patients (7%), antegrade wiring across the site of vascular injury was not possible and a retrograde approach for stent delivery was used. RESULTS: Distal vascular access was achieved via the superficial femoral or profunda artery. Retrograde advancement of a polymer-coated 0.035" wire to the abdominal aorta, followed by stent-graft delivery to the common femoral artery, achieved hemostasis in all cases. During a median (interquartile range) follow-up period of 198 (618) days (range 46-2455) there were no deaths and no patient required additional vascular interventions. CONCLUSIONS: A retrograde approach for stent-graft delivery is feasible and allows percutaneous treatment of a common femoral artery injury following TAVI in patients who are not suitable for the conventional antegrade approach.

RESUMO

The Portico™ transcatheter aortic valve implantation (TAVI) system (Abbott Vascular, Santa Clara, CA, USA) was specifically designed to reduce some of the limitations associated with first-generation TAVI devices. Most of the currently available clinical evidence was obtained from randomized studies that compared TAVI to aortic valve replacement using first-generation transcatheter heart valve devices. The aim of this review is to describe the characteristics of the repositionable and retrievable Portico™ system and the technique of implantation, as well as to provide an overview of the most recent outcomes in the literature, along with our institutional experience.

RESUMO

BACKGROUND: In transcatheter aortic valve implantation (TAVI), prosthesis over-sizing prevents paravalvular leak (PVL). Strategies of over-sizing for self-expanding bioprostheses are not well established at present. METHODS: Patients with aortic valve stenosis scheduled for TAVI underwent preprocedural multislice computed tomography. Based on the degree of over-sizing, a ROC curve was drawn to define the optimal value of valve sizing for reducing PVL after TAVI. RESULTS: A total of 152 consecutive patients were included in the study (mean age, 79.95 ± 7.71 years; log EuroScore: 23.87 ± 8.93%). Based on the ROC curve, sizing of 14% was the optimal that would lead to less moderate/severe PVL (P<.01). Group 1 was defined as sizing <14% (n = 49 patients) and group 2 was defined as sizing ≥14% (n = 103 patients). During a follow-up period of 36 ± 14 months, a total of 9 patients died from group 1 vs 4 patients from group 2 (P<.01). Two of the patients who died had moderate/severe PVL and 11 had no/mild PVL (P=.27). From the population, a total of 49 patients (32%) were found to be in the "borderline" zone. Patients who received the smaller valve had lower mean left ventricular outflow tract diameter (P=.048), higher rate of calcium load (mild: 10 [32%] vs 13 [72%]; moderate: 16 [52%] vs 3 [17%]; severe: 5 [16%] vs 2 [11%]; P=.02) and lower mean of sinus of Valsalva diameter (P=.046) compared with patients who received the bigger valve. CONCLUSIONS: In patients undergoing TAVI, over-sizing the prosthesis at least 14% reduces PVL. In borderline cases, taking into consideration additional anatomical parameters may result in low rates of PVL.

RESUMO

BACKGROUND: Among patients with aortic stenosis who are at intermediate or high risk for death with surgery, major outcomes are similar with transcatheter aortic-valve replacement (TAVR) and surgical aortic-valve replacement. There is insufficient evidence regarding the comparison of the two procedures in patients who are at low risk. METHODS: We randomly assigned patients with severe aortic stenosis and low surgical risk to undergo either TAVR with transfemoral placement of a balloon-expandable valve or surgery. The primary end point was a composite of death, stroke, or rehospitalization at 1 year. Both noninferiority testing (with a prespecified margin of 6 percentage points) and superiority testing were performed in the as-treated population. RESULTS: At 71 centers, 1000 patients underwent randomization. The mean age of the patients was 73 years, and the mean Society of Thoracic Surgeons risk score was 1.9% (with scores ranging from 0 to 100% and higher scores indicating a greater risk of death within 30 days after the procedure). The Kaplan-Meier estimate of the rate of the primary composite end point at 1 year was significantly lower in the TAVR group than in the surgery group (8.5% vs. 15.1%; absolute difference, -6.6 percentage points; 95% confidence interval [CI], -10.8 to -2.5; P<0.001 for noninferiority; hazard ratio, 0.54; 95% CI, 0.37 to 0.79; P = 0.001 for superiority). At 30 days, TAVR resulted in a lower rate of stroke than surgery (P = 0.02) and in lower rates of death or stroke (P = 0.01) and new-onset atrial fibrillation (P<0.001). TAVR also resulted in a shorter index hospitalization than surgery (P<0.001) and in a lower risk of a poor treatment outcome (death or a low Kansas City Cardiomyopathy Questionnaire score) at 30 days (P<0.001). There were no significant between-group differences in major vascular complications, new permanent pacemaker insertions, or moderate or severe paravalvular regurgitation. CONCLUSIONS: Among patients with severe aortic stenosis who were at low surgical risk, the rate of the composite of death, stroke, or rehospitalization at 1 year was significantly lower with TAVR than with surgery.

RESUMO

BACKGROUND: Transcatheter aortic-valve replacement (TAVR) is an alternative to surgery in patients with severe aortic stenosis who are at increased risk for death from surgery; less is known about TAVR in low-risk patients. METHODS: We performed a randomized noninferiority trial in which TAVR with a self-expanding supraannular bioprosthesis was compared with surgical aortic-valve replacement in patients who had severe aortic stenosis and were at low surgical risk. When 850 patients had reached 12-month follow-up, we analyzed data regarding the primary end point, a composite of death or disabling stroke at 24 months, using Bayesian methods. RESULTS: Of the 1468 patients who underwent randomization, an attempted TAVR or surgical procedure was performed in 1403. The patients' mean age was 74 years. The 24-month estimated incidence of the primary end point was 5.3% in the TAVR group and 6.7% in the surgery group (difference, -1.4 percentage points; 95% Bayesian credible interval for difference, -4.9 to 2.1; posterior probability of noninferiority >0.999). At 30 days, patients who had undergone TAVR, as compared with surgery, had a lower incidence of disabling stroke (0.5% vs. 1.7%), bleeding complications (2.4% vs. 7.5%), acute kidney injury (0.9% vs. 2.8%), and atrial fibrillation (7.7% vs. 35.4%) and a higher incidence of moderate or severe aortic regurgitation (3.5% vs. 0.5%) and pacemaker implantation (17.4% vs. 6.1%). At 12 months, patients in the TAVR group had lower aortic-valve gradients than those in the surgery group (8.6 mm Hg vs. 11.2 mm Hg) and larger effective orifice areas (2.3 cm2 vs. 2.0 cm2). CONCLUSIONS: In patients with severe aortic stenosis who were at low surgical risk, TAVR with a self-expanding supraannular bioprosthesis was noninferior to surgery with respect to the composite end point of death or disabling stroke at 24 months.

RESUMO

Endovascular treatment of arterial diseases has become first-line in most cases due to improved technology. However, until recently, excessive atherosclerotic calcification has been a major limiting factor in the endovascular management of peripheral arterial disease, as well as vascular access for endovascular aneurysm repair (EVAR) and transcatheter aortic valve replacement (TAVR). The Peripheral Intravascular Lithotripsy (IVL) System (Shockwave Medical, Inc., Fremont California) applies pulsatile mechanical energy under fluoroscopic guidance to disrupt calcified lesions. The purpose of this paper is to introduce IVL in the treatment of calcific access vessels in preparation for EVAR and TAVR, as well as peripheral arterial disease applications to enhance luminal gain. Using the IVL System, angioplasty can be performed with lower pressures, which may minimize arterial dissection. Further, the lithotripsy effect on calcium will enhance vessel compliance. We describe several cases where IVL was applied successfully and present additional cases that may have benefitted from the use of this technology.

RESUMO

BACKGROUND: Obstruction of the left or right coronary artery is a rare but lethal complication during transcatheter aortic valve implantation (TAVI). The new J-Valve™ prosthesis is a new second generation TAVI device which has several features to avoid the coronary obstruction such as low profile design and clip fixation of the native leaflets. The aim of this study is to report our initial experience of using this valve in treating patient with high risk factors for coronary obstruction during TAVI procedure. CASE PRESENTATION: Three high surgical risk patients (All females with 77, 76, and 75 years old) with symptomatic aortic stenosis were enrolled. All patients have the common feature of low coronary ostium height (< 10 mm) with narrowed aortic sinus (< 30 mm) on CT angiogram and marked leaflet calcification. Three 25 mm J-Valve prostheses were successfully implanted through trans-apical approach. No coronary obstruction was noted for these patients. Effective aortic open area was significantly increased after valve implantation (Preoperative 0.7, 0.7 and 0.65 cm2 - Postoperative 1.8, 1.9 and 2.0 cm2). Only one patient was noted to have trivial degree paravalvular leakage. CONCLUSION: The new J-Valve prosthesis is a new second generation TAVI device. This system may provide another safety treatment option for patient with high risk factor for coronary obstruction underwent TAVI procedure.

RESUMO

AIMS: To compare transcatheter aortic valve replacement TAVR with self-expandable first-generation Medtronic CoreValve with new-generation Evolut R devices in patients with aortic stenosis. METHODS: Multiple databases were screened for all available reports directly or indirectly comparing CoreValve vs Evolut R. Primary endpoint was device success. Procedural, functional and clinical outcomes were assessed as well. RESULTS: Ten retrospective series including 12 294 pts. were found. Overall device success rate was 95.5% and was statistically higher in the Evolut R treated patients as compared with CoreValve: 96.6 vs. 94.8%, respectively; RR (risk ratio) 95%CIs (confidence intervals): 1.02 (1.00-1.04); P = 0.01. There were no statistical differences with regard to postoperative mean aortic gradients 8.5 +/- 5.3 vs 7.9 +/- 4.6 with Evolut R and CoreValve. Evolut R valve demonstrated nearly 50% reduction of the risk for moderate-to-severe paravalvilar leak 0.55 (0.39-0.79); P = 0.001; 60% statistically significant lower risk of developing myocardial injury 0.40 (0.22-0.72); P = 0.002 and numerical reductions in the risk of acute kidney injury, vascular complications and bleeding. Together with significantly reduced risk of permanent pacemaker implantation (0.80 [0.67-0.96]; P = 0.02) the above benefits were associated with 40% reduction in the risk of 30-day all-cause mortality with Evolut R as compared to CoreValve: 0.60 (0.37-1.00); P = 0.05. CONCLUSIONS: The use of new-generation Evolut R was associated with improved procedural, functional and clinical outcomes compared with the CoreValve device.

RESUMO

BACKGROUND: The mechanically expandable Lotus Valve System is a fully repositionable and retrievable valve with an adaptive seal to minimize paravalvular leak (PVL). The aim of this study was to evaluate the short- and long-term safety and efficacy of the new device with focus on a new implantation technique to reduce the need for a permanent pacemaker (PPM) post procedure. METHODS: We performed a prospective single-center, non-randomized evaluation of the Lotus Valve System. The first 100 consecutive Lotus Valve implantations were included in the analysis. Outcome was assessed according to VARC2-criteria. Postoperative pacemaker rates were assessed using the national pacemaker registry and electronic medical records. Mortality at 30 days and 12 months were acquired from the national population registry. RESULTS: Mean age was 82.7 ± 5.6 years, mean Euroscore I was 25.3 ± 14.5%, mean STS-score was 6.5 ± 4.1% and mean aortic valve area was 0.6 ± 0.1 cm2. There were no cases of valve embolization, ectopic valve deployment or additional valve implantation. Device success according to the VARC2-criteria was 97%. The 30-day mortality rate was 3%. Two deaths occurred due to stroke and one due to a ventricular rupture. Major stroke rate was 2% and major vascular complication rate was 2%. The 12-month mortality rate was 14%. At discharge 87% of patients had no/trace PVL, 12% had mild PVL and one patient had a moderate PVL. A total of 13% received a new PPM post valve implantation. Among patients who did not have a PPM before the procedure, the PPM rate was 15.3%. CONCLUSIONS: This single-center evaluation of the Lotus Valve System demonstrated a good clinical outcome with a low mortality, in a high-risk population. Introduction of a new implantation technique resulted in lower PPM rates than previously reported without negatively affecting PVL.

RESUMO

Cirrhosis is a significant adverse factor of cardiac surgeries. Transcatheter aortic valve implantation (TAVI) has evolved as a less invasive therapy for aortic stenosis, whereas detailed case analysis of TAVI in cirrhotic patients is limited.Among 444 consecutive patients who underwent TAVI in the Sakakibara Heart Institute between October 2013 and January 2018, we retrospectively reviewed 11 patients (2.5%) with cirrhosis. All outcomes were defined according to the Valve Academic Research Consortium-2 criteria.The median age of the patients was 82 years, and eight (73%) were female. Seven patients (64%) were Child-Turcotte-Pugh class A, and four patients (36%) were class B. The Model for End-Stage Liver Disease score was 10 (7.0-13). TAVI was performed using Edwards SAPIEN XT/SAPIEN3 in nine patients (82%), and Medtronic CoreValve/Evolut R in two patients (18%), via transfemoral (n = 8, 73%) or transapical (n = 3, 27%) approach. The device success rate was 100% and no extracorporeal circulation had been inducted. No death, stroke, life-threatening bleeding, and acute kidney injury stage 2 or 3 occurred within 30 days, but three major bleeding events (27%) were documented (two access-site bleeding in transapical approach, and one pulmonary hemorrhage caused by transient mitral regurgitation). During a median follow-up of 493 days, four deaths had occurred, and the mid-term survival rate was 81% and 65% at one and two years each.TAVI is a promising therapeutic option for patients with cirrhosis. Further study should be needed regarding optimal patient selection and procedures in patients with cirrhosis.

RESUMO

BACKGROUND: Very little is known about long-term valve durability after transcatheter aortic valve replacement (TAVR). OBJECTIVES: This study sought to evaluate the incidence of structural valve degeneration (SVD) 5 to 10 years post-procedure. METHODS: Demographic, procedural, and in-hospital outcome data on patients who underwent TAVR from 2007 to 2011 were obtained from the U.K. TAVI (United Kingdom Transcatheter Aortic Valve Implantation) registry. Patients in whom echocardiographic data were available both at baseline and ≥5 years post-TAVR were included. Hemodynamic SVD was determined according to European task force committee guidelines. RESULTS: A total of 241 patients (79.3 ± 7.5 years of age; 46% female) with paired post-procedure and late echocardiographic follow-up (median 5.8 years, range 5 to 10 years) were included. A total of 149 patients (64%) were treated with a self-expandable valve and 80 (34.7%) with a balloon-expandable valve. Peak aortic valve gradient at follow-up was lower than post-procedure (17.1 vs. 19.1 mm Hg; p = 0.002). More patients had none/trivial aortic regurgitation (AR) (47.5% vs. 33%), and fewer had mild AR (42.5% vs. 57%) at follow-up (p = 0.02). There was 1 case (0.4%) of severe SVD 5.3 years after implantation (new severe AR). There were 21 cases (8.7%) of moderate SVD (mean 6.1 years post-implantation; range 4.9 to 8.6 years). Twelve of these (57%) were due to new AR and 9 (43%) to restenosis. CONCLUSIONS: Long-term transcatheter aortic valve function is excellent. In the authors' study, 91% of patients remained free of SVD between 5 and 10 years post-implantation. The incidence of severe SVD was <1%. Moderate SVD occurred in 1 in 12 patients.
