Sex-Related Differences in Life Expectancy Compared to General Population after Surgery for Ascending Aortic Aneurysm.

Background/Objectives: Understanding sex-based differences in cardiovascular outcomes is paramount to improving clinical outcomes. Surgery is an aggressive but effective therapy for ascending aortic aneurysm. We sought to determine if being a woman is a risk factor for long-term mortality after this surgery. We compared their life expectancy with a general population of the same age, sex, year, and region. Methods: We compared men and women undergoing AAA surgery at our institution from 2000 to 2019. After balancing the population with propensity score (PS) matching, we compared long-term mortality control with a Cox regression. We determined the RS using the Ederer II method and compared it to a healthy reference population of the same age, sex, and region. Results: From 2000 to 2019, 232 women and 506 men underwent ascending aortic aneurysm surgery. After a mean follow-up of 51.5 ± 34.5 months, sex was not an independent risk factor for long-term mortality in the multivariable analysis [HR: 0.68 (95% CI 0.43-1.07, p = 0.23)]. Matching by baseline characteristics, 196 pairs were analyzed with no differences regarding mortality in the Cox regression [HR: 1.11 (95% CI 0.65-1.9, p = 0.23)]. Men and women who survived the postoperative period presented a relative survival of 100.3% (95% CI 97.4-101%) and 100.3% (95% CI 98.9-101.1%), respectively, similar to the reference population without the disease. Conclusions: For patients undergoing AAA surgery, sex was not an independent predictor of mortality. Men and women who survived the postoperative period presented a similar life expectancy to that of the reference population (people free from the disease of the same age, sex, year, and region).

Late bleeding events in TAVI patients receiving vitamin K antagonists or direct oral anticoagulants.

INTRODUCTION AND OBJECTIVES: The optimal chronic antithrombotic regimen for patients with atrial fibrillation undergoing transcatheter aortic valve implantation (TAVI) remains uncertain. Our aim was to compare the incidence of late bleeding events between patients on direct oral anticoagulants (DOACs) and those on vitamin-K antagonists (VKA). METHODS: This single-center observational study included TAVI patients requiring oral anticoagulation at discharge between 2015 and 2021. The primary endpoint was any clinically significant bleeding event. Secondary endpoints were stroke, heart failure, and all-cause mortality. RESULTS: A total of 702 TAVI procedures were performed, with 297 patients requiring oral anticoagulation at discharge. Among them, 206 (69.4%) received VKA and 91 (30.6%) received DOAC. Baseline clinical, procedural and in-hospital characteristics did not significantly differ between groups, except for better renal function among DOAC patients. The median length of follow-up was 2.8 years. The risk of bleeding events was higher in patients receiving DOACs than in those receiving VKA (HR, 2.27; 95%CI, 1.21-4.26; incidence of 9.7 and 4.2 events per 100 patient-years of follow-up for DOAC and VKA patients, respectively). There were no statistically significant differences in the rates of stroke (HR, 1.28; 95%CI, 0.4-4.3), heart failure hospitalization (HR, 0.92; 95%CI, 0.46-1.86), or all-cause mortality (HR, 1.02; 95%CI, 0.68-1.55). CONCLUSIONS: In older patients undergoing TAVI and receiving anticoagulant therapy for atrial fibrillation, the use of DOAC was associated with a higher risk of late bleeding events than VKA.

Hemodynamic performance of self-expandable transcatheter aortic valve replacement systems during valve deployment.

OBJECTIVES: Little is known about valve hemodynamic performance during the Evolut and Neo deployment course. We aimed to evaluate transvalvular mean and peak-to-peak gradients over several intraprocedural timepoints during TAVR with Evolut PRO+ (Medtronic) and Neo (Boston Scientific) systems. METHODS: This was single-center pilot sub-study from the SavvyWire EFficacy and SafEty in Transcatheter Aortic Valve Implantation Procedures (SAFE-TAVI) trial. Participants received either the Evolut PRO+ or Neo for native valve severe aortic stenosis and the SavvyWire (OpSens Medical) was used for device delivery, pacing, and continuous left ventricular and aortic pressure measurements. For the Evolut, evaluation was done for baseline, two-thirds of valve deployment (still recapturable), 90% of valve deployment (no longer recapturable), and post-deployment hemodynamics. For the Neo, analysis was done at baseline, after the first step (top-crown deployment), and at final status. RESULTS: Nineteen patients were included (Evolut = 15; Neo = 4). There were no statistically significant changes in peak-to-peak gradients (44 mm Hg [IQR:33-69] vs 43 mm Hg [IQR:26-62], P = .41) between baseline and two-thirds of valve deployment in the Evolut patients. There was a significant decrease in mean (40 mm Hg [IQR:32-54] vs 14 mm Hg [IQR:10-18], P less than .001) and peak-to-peak (43 mmHg [IQRS:26-62] vs 9 mm Hg [IQR:8-13], P less than .001) transvalvular gradients between two-thirds and 90% of valve deployment for Evolut. Neo patients exhibited a decrease in transvalvular gradients after top-crown deployment (42.5 mm Hg baseline vs 13 mm Hg). CONCLUSIONS: Transvalvular gradients did not vary between the point of "no-recapture" compared to baseline values in patients receiving the Evolut, whereas a significant reduction in transvalvular gradients was observed when the valve was deployed at 90% and fully deployed. The Neo valve was slightly obstructive after the first step of deployment.

IAMCEST en mujeres. Recuperación de la expectativa de vida tras la intervención coronaria percutánea / STEMI in women. Life expectancy recovery after primary percutaneous coronary intervention

Introducción y objetivos: La mortalidad tras un infarto agudo de miocardio con elevación del segmento ST (IAMCEST) sigue siendo alta a pesar de los avances médicos. Las mujeres están poco representadas en los estudios, lo que limita el conocimiento sobre su tratamiento y su pronóstico. Se desconoce si las mujeres tratadas con intervención coronaria percutánea (ICP) primaria recuperan una esperanza de vida similar a una población de referencia. El objetivo del estudio es determinar si las mujeres sometidas a ICP primaria recuperan una supervivencia similar a la población general de iguales edad y región. Métodos: Se incluyeron todos los IAMCEST desde enero de 2014 a octubre de 2021. Se emparejó la muestra con una población de referencia de iguales edad y región, obtenida del Instituto Nacional de Estadística. Se determinaron las supervivencias observada y esperada y el exceso de mortalidad (EM) mediante el método Ederer II. Se repitió el análisis para mujeres de edad ≤ 65 y> 65 años. Resultados: Se reclutó a 2.194 personas; 528 casos eran mujeres (23,9%). Entre las mujeres que sobrevivieron los primeros 30 días, los EM del 1.er, el 5.o y el 7.o año fueron del 1,6% (IC95%, 0,3-4), el 4,7% (IC95%, 0,3-10,1) y el 7,21% (IC95%, 0,5-15,1) respectivamente. Conclusiones: Las mujeres con un IAMCEST tratadas con ICP primaria que sobreviven al evento agudo reducen significativamente su EM y presentan una esperanza de vida similar a la de la población de referencia de iguales edad y región.(AU)

Introduction and objectives: Despite medical advances, mortality after ST-elevation myocardial infarction (STEMI) remains high. Women are often underrepresented in trials and registries, limiting knowledge of their management and prognosis. It is unknown whether life expectancy in women of all ages treated with primary percutaneous coronary intervention (PPCI) is similar to that in a reference population free of the disease. The main objective of this study was to determine whether life expectancy in women undergoing PPCI and surviving the main event returns to a similar level to that in the general population of the same age and region. Methods: We included all patients diagnosed with STEMI from January 2014 to October 2021. We matched women to a reference population of the same age and region from the National Institute of Statistics to determine observed survival, expected survival, and excess mortality (EM) using the Ederer II method. We repeated the analysis in women aged ≤ 65 and> 65 years. Results: A total of 2194 patients were recruited, of whom 528 were women (23.9%). In women surviving the first 30 days, EM at 1, 5 and 7 years was 1.6% (95%CI, 0.3-4), 4.7% (95%CI, 0.3-10.1), and 7.2% (95%CI, 0.5-15.1), respectively. Conclusions: EM was reduced in women with STEMI who were treated with PPCI and who survived the main event. However, life expectancy remained lower than that in a reference population of the same age and region.(AU)

Current status of transcatheter mitral valve replacement: systematic review and meta-analysis.

Introduction: Mitral Regurgitation (MR) has a strong impact on quality of life and on mid-term survival. Transcatheter mitral valve replacement (TMVR) is rapidly expanding and a growing number of studies have been published recently. Methods: A systematic review of studies reporting on clinical data for patients with symptomatic severe MR undergoing TMVR was performed. Early- and mid-term outcomes (clinical and echocardiographic) were evaluated. Overall weighted means and rates were calculated. Risk ratios or mean differences were calculated for pre- and post-procedural comparisons. Results: A total of 12 studies and 347 patients who underwent TMVR with devices clinically available or under clinical evaluation were included. Thirty-day mortality, stroke and major bleeding rates were 8.4%, 2.6%, and 15.6%, respectively. Pooled random-effects demonstrated a significant reduction of ≥ grade 3+ MR (RR: 0.05; 95% CI: 0.02-0.11; p < 0.001) and in the rates of patients in NYHA class 3-4 after the intervention (RR: 0.27; 95% CI: 0.22-0.34; p < 0.001). Additionally, the pooled fixed-effect mean difference for quality of life based on the KCCQ score yielded an improvement in 12.9 points (95% CI:7.4-18.4, p < 0.001), and exercise capacity improved by a pooled fixed-effect mean difference of 56.8 meters in the 6-minute walk test (95% CI 32.2-81.3, p < 0.001). Conclusions: Among 12 studies and 347 patients comprising the updated evidence with current TMVR systems there was a statistically significant reduction in ≥ grade 3+ MR and in the number of patients exhibiting poor functional class (NYHA 3 or 4) after the intervention. Overall rate of major bleeding was the main shortcoming of this technique.

Resultados a corto y medio plazo de la reparación transcatéter de la válvula tricúspide: revisión sistemática y metanálisis de estudios observacionales / Early and mid-term outcomes of transcatheter tricuspid valve repair: systematic review and meta-analysis of observational studies

Introducción y objetivos La insuficiencia tricuspídea (IT) se asocia con un peor pronóstico si no se corrige. Se han publicado recientemente numerosos estudios sobre reparación transcatéter de la válvula tricúspide (RTT) Métodos Se llevó a cabo una revisión sistemática de estudios que publican datos clínicos de pacientes con IT significativa sometidos a RTT. Se evaluaron objetivos clínicos y ecocardiográficos a corto y medio plazo. Las razones de riesgo (RR) y las diferencias de medias (DM) se obtuvieron de la comparación de datos previos y posteriores a la intervención. Se hizo también un análisis de sensibilidad según el abordaje principal (reparación borde a borde frente a anuloplastia) Resultados Se incluyeron 19 estudios (todos observacionales o ensayos de un solo grupo) con un total de 991 pacientes sometidos a RTT sola. Las tasas de mortalidad e ictus a 30 días fueron del 2,8 y el 0,2% respectivamente. El análisis agrupado de efectos aleatorios mostró una reducción significativa de IT (RR=0,33; IC95%, 0,26-0,42; p <0,001), vena contracta (DM, 5,9mm; IC95%, 4-7,9; p <0,001), diámetro telediastólico del ventrículo derecho (DM, 3,5mm; IC95%, 2,5-4,5; p <0,001) y clase funcional de la NYHA 3 o 4 (RR=0,32; IC95%, 0,27-0,37; p <0,001) a los 30 días. Las complicaciones hemorrágicas y la IT residual al menos grave fueron numéricamente superiores en el grupo de anuloplastia percutánea en comparación con el grupo de reparación borde a borde (hemorragias, el 13,3 y el 2,8%; IT residual, el 40,4 y el 27,9%) Conclusiones En los 991 pacientes que formaron parte de la experiencia inicial de RTT, tras la intervención se observó una reducción estadísticamente significativa del grado de IT grave o peor, una mala clase funcional (NYHA 3-4), la anchura de la vena contracta y el diámetro telediastólico del ventrículo derecho. Hasta ahora, el abordaje con reparación borde a borde parece tener un mejor perfil de seguridad (AU)

Introduction and objectives Severe tricuspid regurgitation (TR) is associated with poor prognosis when left untreated, and a growing number of studies on transcatheter tricuspid valve repair (TTVr) have been published over the last few months. Methods We performed a comprehensive systematic review of published literature providing clinical data on TTVr for patients with significant TR. Early and mid-term clinical and echocardiographic outcomes were evaluated. Risk ratios (RR) or mean differences (MD) were obtained when comparing pre- and postprocedural data. A sensitivity analysis was also performed according to the main approach for repair (edge-to-edge vs annuloplasty). Results A total of 19 studies (all observational or single-arm trials) and 991 patients who underwent isolated TTVr were included. Thirty-day mortality and stroke rates were 2.8% and 0.2%, respectively. Pooled random-effects resulted in a significant reduction of ≥ severe TR (RR, 0.33; 95%CI, 0.26-0.42; P<.001), vena contracta width (MD, 5.9mm; 95%CI, 4-7.9; P <.001), right ventricular end-diastolic diameter (MD, 3.5mm; 95%CI, 2.5-4.5; P <.001), and New York Heart Association (NYHA) class III or IV at last follow-up (RR, 0.32; 95%CI, 0.27-0.37; P <.001). Bleeding complications and residual ≥ severe TR were numerically higher in the annuloplasty-like group compared with edge-to-edge repair (13.3% vs 3.8% for bleeding and 40.4% vs 27.9% for residual severe TR). Conclusions Among 991 patients comprising the early experience for several TTVr devices, there was a statistically significant reduction in ≥ severe TR, NYHA class III-IV, vena contracta width and right ventricular end-diastolic diameter after TTVr. Thus far, the edge-to-edge approach seems to be associated with a better safety profile (AU)

Leaving obstacles aside: Antegrade paravalvular leakage closure after transcatheter aortic valve replacement.

Paravalvular leakage (PVL) is yet a potential and serious complication after transcatheter aortic valve replacement. Percutaneous PVL closure may be the treatment of choice upon failure of balloon postdilation in patients with excessive surgical risk. If the retrograde approach fails, an antegrade strategy might provide the solution.

Functional continuum: independent predictor of one-year mortality and key decision-making element in older adults with severe aortic stenosis amenable to aortic valve replacement.

OBJECTIVES: The impact of functional capacity over the entire functional continuum in older adults undergoing aortic valve replacement (AVR) has not been studied to date. This study aims to analyze 1.- the distribution of a cohort of older adults presenting severe aortic stenosis (AS) amenable to AVR in the different categories of the Functional Continuum Scale (FCS); 2.- its association with decision-making regarding valve disease; and 3.- its impact upon the one-year mortality rate of surgical (SAVR), transcatheter (TAVR) aortic valve replacement, or the decision to provide conservative management (OMT). METHODS: This prospective study included patients from the FRESAS (FRailty-Evaluation-in-Severe-Aortic-Stenosis) registry evaluated by the reference Heart-Team of a region in northern Spain. All the patients underwent comprehensive geriatric assessment. RESULTS: The study comprised 257 patients aged 84.0 ± 3.9 years. MANAGEMENT: SAVR: 25.3%, TAVR: 58.0% and OMT: 16.7%. Increased patient functional capacity was associated with an increased tendency to perform more invasive valve disease treatment. The overall one-year survival rate was 81.3%. One-year all-cause mortality: FCS-1 to FCS-2 "robust" 11.5%, FCS-3 to FCS-4 "prefrail" 14.7%, FCS-5 "frail" 19.2% and FCS-6 to FCS-8 "dependent" 45.0%; p < 0.001. Adjusted mortality analysis: FCS with HR = 1.206 [95%CI, 0.999-1.451 (p = 0.051)]; EuroSCORE-II with HR = 1.071 [95%CI, 1.006-1.161 (p = 0.033)]; and OMT with HR = 2.840 [95%CI, 1.409-5.772 (p = 0.004)] were retained in the final multivariable logistic regression model. CONCLUSIONS: In older AS patients amenable to AVR, the FCS is a useful predictive tool that may aid clinical decision-making.

Transcatheter tricuspid valve interventions: Current status and future perspectives.

The development of transcatheter therapies to treat valvular heart diseases has changed the rules of the game, particularly in the case of aortic stenosis and mitral regurgitation. In the last years, the tricuspid valve has also been the focus of these percutaneous techniques for several reasons: (1) tricuspid regurgitation is a frequent disease associated with poor clinical outcomes in spite of medical treatment, leading to end-stage right ventricular heart failure, (2) surgical tricuspid valve repair or replacement has been the treatment of choice for patients with tricuspid valve disease, but high mortality rates for isolated surgical tricuspid valve intervention have been reported in the literature, and (3) most patients with tricuspid pathology are ultimately denied cardiac surgery because of their comorbidity burden. Thus, in this context the development of less invasive catheter-based therapies would be of high clinical relevance. The present review provides an overview regarding the framework of chronic tricuspid regurgitation transcatheter therapeutic options, summarizes the transcatheter systems under clinical use or clinical evaluation with their technical features, and describes the updated current evidence in this challenging and evolving field.

Bioresorbable stents: Is the game over?

Bioresorbable scaffolds (BRS) emerged as an alternative to conventional stents with a fundamental idea, to avoid a permanent metallic cage with all its harmful effects on the vessel. The Absorb BVS was the first widely studied device with the promising concept of performing a percutaneous coronary intervention, giving the necessary initial support to maintain vessel integrity and avoid acute vessel thrombosis. After a period, complete resorption of the device without leaving in the vessel any metallic structure would theoretically offer several benefits as the reduction of the inflammatory response and recovering normal vasomotor function, recovering access of jailed side-branches and segments for surgical revascularization, and the reduction of very late stent thrombosis derived from late acquired malapposition. However, cumulative evidence from the different absorb randomized trials (ABSORB II, ABSORB III, ABSORB China, ABSORB Japan) raised significant concerns, due to an elevated rate of scaffold thrombosis, target lesion failure and target vessel failure, when compared to contemporary everolimus drug-eluting stents. Several mechanisms arose explaining scaffold failure; some were strictly related to the device itself, and others related to the operator and the lesion itself. Newer generation BRS are under development targeting the main limitations of the ABSORB BVS, mainly focusing on reducing strut thickness, improving the mechanical structure with faster resorption times, and a better crossing profile. The story of BRS is not over yet, with ongoing refinements in the quest for the ideal stent.

Transseptal puncture: Review of anatomy, techniques, complications and challenges, a critical view.

Transseptal puncture (TSP) was initially described to gain access to the left heart for hemodynamic assessment. Continuous evolution from its origins allows interventionists to perform a myriad of procedures that otherwise would be impossible to accomplish. In the recent years, the number of procedures in cardiology that require TSP has grown exponentially. Namely, transcatheter mitral valve repair and replacement, pulmonary vein isolation and left atrium appendage occlusion. In skilled hands, it is a safe and straightforward procedure; however, a lack of knowledge of the materials, anatomy of the interatrial septum and the technique can be met with life-threatening complications. Therefore, it is imperative that interventional cardiologists master this technique to successfully overcome these obstacles and ensure clinical outcomes in patients requiring TSP. The purpose of the following review is to critically analyze the available evidence regarding TSP, provide a step-by-step approach to the technique, the available materials and tips and tricks to overcome difficulties and manage complications.

Permanent Pacemaker Reduction Using Cusp-Overlapping Projection in TAVR: A Propensity Score Analysis.

OBJECTIVES: The aim of this study was to determine if modifying the classical implantation technique for self-expanding (SE) transcatheter aortic valve replacement to a novel cusp-overlapping projection (COP) technique results in a higher implantation depth (ID) and subsequently reduces the rate of permanent pacemaker implantation (PPMI). BACKGROUND: The COP technique presents the potential benefit of an optimized ID to reduce the rate of PPMI. However, only a few studies have compared clinical outcomes with those achieved using the standard technique. This is the first study to systematically evaluate this approach for SE transcatheter heart valves (THVs) in different populations METHODS: Beginning in February 2015, 444 patients were consecutively included. Propensity score matching was used to control baseline characteristics because of the observational nature of the study. In total, 161 pairs of patients were analyzed. Three methods were used to measure ID (noncoronary cusp [NCC] to the THV, mean of the NCC and the left coronary cusp [LCC] to the THV, and the deepest edge from the LCC and the NCC to the THV). RESULTS: ID was significantly higher in COP cases when measuring from the NCC (4.2 mm vs 5.3 mm; P < 0.001) and the mean from the NCC and the LCC (5.3 mm vs 5.9 mm; P = 0.04), but not from the deepest edge. The PPMI rate was lower in the COP group: 19 (11.8%) vs 35 (21.7%) (P = 0.03; relative risk: 0.54; 95% CI: 0.32-0.91). CONCLUSIONS: The present study showed that the COP technique significantly reduces PPMI in SE THV implantation compared with the classical implantation technique, with similar rates of complications.

Cusp-overlapping TAVI technique with a self-expanding device optimizes implantation depth and reduces permanent pacemaker requirement.

INTRODUCTION AND OBJECTIVES: This study aimed to determine the safety and efficacy of modifying the classic implantation technique for aortic transcatheter heart valve (THV) implantation to a cusp-overlap-projection (COP) technique to achieve a higher implantation depth and to reduce the burden of new permanent pacemaker implantation (PPMI) at 30 days. Aortic self-expanding THV carries an elevated risk for PPMI. A higher implantation depth minimizes the damage in the conduction system and may reduce PPMI rates. METHODS: From March 2017, 226 patients were consecutively included: 113 patients were treated using the COP implantation technique compared with the previous 113 consecutive patients treated using the classic technique. In all patients, implantation depth was assessed by 3 methods (noncoronary cusp to the THV, mean of the noncoronary cusp and the left coronary cusp to the THV, and the deepest edge from the left coronary cusp and the noncoronary cusp to the THV). RESULTS: The COP group had a lower implantation depth than the group treated with the classic technique (4.8 mm± 2.2 vs 5.7 mm± 3.1; P=.011; 5.8 mm± 3.1 vs 6.5 mm± 2.4; P=.095; 7.1 mm± 2.8 vs 7.4 mm±3.2; P=.392). Forty patients (17.7%) required a new PPMI after the 30-day follow-up but this requirement was significantly lower in the COP group (12.4% vs 23%, P=.036). The COP implantation technique consistently protected against the main event (OR, 0.45; 95%CI, 0.21-0.97; P=.043), with similar procedural success rates and complications. CONCLUSIONS: The COP implantation technique is a simple modification of the implantation protocol and provides a higher implantation depth of self-expanding-THV with lower conduction disturbances and PPMI rates.

Frailty Assessment in a Cohort of Elderly Patients with Severe Symptomatic Aortic Stenosis: Insights from the FRailty Evaluation in Severe Aortic Stenosis (FRESAS) Registry.

BACKGROUND: Precise evaluation of the degree of frailty is a fundamental part of the global geriatric assessment that helps to avoid therapies that could be futile. Our main objective was to determine the prevalence of frailty in a specific consult of patients undergoing aortic valve replacement. METHODS: From May 2018 to February 2020, all consecutive patients ≥75 years old, with severe symptomatic aortic stenosis, undergoing valve replacement in the Principality of Asturias (Northern Spain) were evaluated. RESULTS: A total of 286 patients were assessed. The mean age was 84 ± 4.01 years old; 175 (61.2%) were female. The short performance physical battery score was 8.5 ± 2.4 and the prevalence of frailty was 19.6% (56 patients). In the multivariable analysis, age, Barthel index and atrial fibrillation were independent predictors of frailty. CONCLUSIONS: The prevalence of frailty in our sample patients undergoing aortic valve replacement, evaluated by a standardized protocol, was 19.6%.

STEMI, primary percutaneous coronary intervention and recovering of life expectancy: insights from the SurviSTEMI study.

INTRODUCTION AND OBJECTIVES: In the last few decades, there has been a continuous process of improvement in medical treatment and secondary prevention measures after ST-segment elevation myocardial infarction (STEMI). Patients older than 65 years are at increased risk of death due to this event. Our aim was to determine whether patients aged less than 65 years and 65 years and older experiencing a STEMI can recover a life expectancy similar to that of the general population of the same age, sex, and geographical region. METHODS: We included all patients experiencing a STEMI at our institution during a 6-year period in an observational-study (SurviSTEMI: survival in STEMI). We calculated their observed survival, expected survival, and excess mortality. We repeated all analyses for survivors of the acute event stratifying by 65 years. RESULTS: For patients aged <65 years who survived the STEMI, observed survival at 3 and 5 years of follow-up was 97.68% (95%CI, 96.05%-98.64%) and 94.14% (95%CI, 90.89%-96.25%), respectively. Expected survival at 3 and 5 years was 98.12% and 96.61%. For patients ≥ 65 years who survived the STEMI, observed survival at 3 and 5 years was 85.52% (95%CI, 82.23%-88.24%) and 75.43% (95%CI, 70.26%-79.83%), respectively. Expected survival at 3 and 5 years was 86.48% and 76.56%, respectively. CONCLUSIONS: For survivors of the acute event, life expectancy is fairly similar to that of the general population of the same age, sex, and geographical region.

Long term follow up of percutaneous treatment for degenerated Mitroflow prosthesis with self-expanding transcatheter aortic valve implantation.

BACKGROUND: The durability of aortic valve bioprosthesis and the structural valve deterioration (SVD) are could be treated with valve-in-valve (VIV) transcatheter aortic valve implantation (TAVI). This technique has been proven to be a feasible procedure with good results in selected patients. The aim of this work was to assess the long-term results of this TAVI with an autoexpandable valve in patients with failed Mitroflow (MF) bioprosthetic aortic valves. METHODS: Single center, observational and prospective study that included 65 consecutive patients with symptomatic failed MF bioprosthetic aortic valve, treated with VIV-TAVI. The primary endpoints were clinical long-term events including all-cause mortality, cardiovascular mortality, re-hospitalization due to heart failure, stroke/transient ischemic attack (TIA) and endocarditis. Secondary endpoints were the absence of SVD or patient-prosthesis mismatch (PPM) and valve hemodynamics analysis at follow-up. RESULTS: Between March 2012 to July 2019, 65 symptomatic patients (age 80.4±5.9 years) with degenerated MF valves (numbers 19: 27.7%; 21: 38.5%; 23: 21.5%; 25: 12.3%) underwent CoreValve (n=11) or Evolut R (n=54) implantation (23, 26 and 29 mm sizes). The STS predicted risk of mortality was 6.39%±5.62%. The primary combined endpoint occurred in 32.3% of the cases. A total of 13 patients (20%) died during follow-up, but 4 (7.3%) from cardiovascular causes. Two patients were reported of having a stroke/TIA and 5 readmissions for cardiovascular causes were reported (2 of them within the first 30 days). Twenty-five patients (38.5%) presented PPM during follow-up, being PPM severe in 15 (23.1%). CONCLUSIONS: Self-expanding TAVI for degenerated MF bioprosthesis has favourable long-term outcomes. It is a good option in order to avoid the risks of redo surgery in selected patients.
