Prognosis for Mitral Valve Repair Surgery in Functional Mitral Regurgitation.

PURPOSE: Our aim was to evaluate the development of new significant mitral regurgitation and long-term survival after mitral repair surgery in functional mitral regurgitation. METHODS: A retrospective observational analysis of the recurrence of functional mitral regurgitation (ischemic and nonischemic) and global mortality during follow-up of 176 patients who underwent mitral repair surgery between 1999 and 2018 in our center was conducted. RESULTS: The etiology of functional mitral regurgitation was ischemic in 55.7% of cases. After surgery, mitral regurgitation was 0-I in 92.3% of cases. We conducted a long-term clinical follow-up of a mean 42.2 months and an echocardiographic follow-up of a mean 41.8 months. We observed mitral regurgitation of at least grade II in 52 patients (36.9%). Survival at 1, 3, and 5 years was 78.8%, 66.7%, and 52.3%, respectively. Predictive factors for global mortality were age (hazard ratio = 1.038, p = 0.01) and a depressed preoperative ejection fraction. After a competing risk analysis, we found the only predictive factor for the recurrence of mitral regurgitation in our series to be age (sub-hazard ratio = 1.03, 95% confidence interval = 1.01-1.06, p = 0.016). CONCLUSION: Repair surgery for functional mitral regurgitation shows age as the only independent predictor of recurrence. Age and depressed ejection fraction were predictors of mortality.

Influencia de una estrategia de alerta multidisciplinaria en la mortalidad por endocarditis infecciosa izquierda / Influence of a Multidisciplinary Alert Strategy on Mortality Due to Left-sided Infective Endocarditis

Introducción y objetivos La mortalidad por endocarditis infecciosa izquierda continúa siendo muy elevada. El objetivo de este estudio es valorar el impacto en la mortalidad precoz de la endocarditis infecciosa izquierda de una estrategia de alerta multidisciplinaria (AMULTEI, basada en la alerta clínica, ecocardiográfica y microbiológica) iniciada en 2008 en un centro hospitalario de tercer nivel. Métodos Estudio de cohortes que compara nuestra serie histórica (1996-2007) con la serie de pacientes de 2008-2011 diagnosticada de endocarditis izquierda (AMULTEI).Resultados La cohorte AMULTEI incluye a 72 pacientes, frente a los 155 de la cohorte histórica. Los pacientes AMULTEI presentaron significativamente más edad (62,5 frente a 57,9 años en la cohorte histórica; p = 0,047) y más comorbilidad (índice de Charlson, 3,33 frente a 2,58 en la cohorte histórica; p = 0,023). Se observó una tendencia a más etiología enterocócica (el 20,8% del grupo AMULTEI frente al 11,6% de la cohorte histórica; p = 0,067). Se realizó cirugía sin demora durante el ingreso hospitalario más frecuentemente (el 48,6 frente al 23,2%; p < 0,001). Se redujo significativamente la incidencia de shock séptico (el 9,7 frente al 24,5%; p = 0,009) y hubo una tendencia a reducirse las complicaciones neurológicas (el 19,4 frente al 29,0%; p = 0,25) y la insuficiencia cardiaca grave (el 12,5 frente al 18,7%; p = 0,24). Las mortalidades hospitalaria y durante el primer mes de seguimiento disminuyeron significativamente (el 16,7 frente al 36,1%; p = 0,003).Conclusiones A pesar de la tendencia a mayor edad y más comorbilidad medida por índice de Charlson, los pacientes tratados con la estrategia AMULTEI presentaron una reducción significativa de la mortalidad precoz (AU)

Introduction and Objectives Mortality from left-sided infective endocarditis remains very high. The aim of this study was to assess the impact of a multidisciplinary alert strategy (AMULTEI), based on clinical, echocardiographic and microbiological findings, implemented in 2008 in a tertiary hospital. Methods Cohort study comparing our historical data series (1996-2007) with the number of patients diagnosed with left-sided endocarditis from 2008-2011 (AMULTEI).Results The AMULTEI cohort included 72 patients who were compared with 155 patients in the historical cohort. AMULTEI patients were significantly older (62.5 vs 57.9 years in the historical cohort; P=.047) and had higher comorbidity (Charlson index, 3.33 vs 2.58 in the historical cohort; P=.023). There was also a trend toward more enterococcal etiology in the AMULTEI group (20.8% vs 11.6% in the historical cohort; P=.067). In the AMULTEI group, early surgery was more frequently performed (48.6% vs 23.2%; P<.001) during hospitalization, the incidence of septic shock was significantly lower (9.7% vs 24.5%; P=.009) and there was a trend toward reductions in neurological complications (19.4% vs 29.0%; P=.25) and severe heart failure (12.5% vs 18.7%; P=.24). In-hospital mortality and mortality during the first month of follow-up were significantly lower in the AMULTEI group (16.7% vs 36.1%; P=.003).Conclusions Despite the trend toward older age and more comorbidity measured by the Charlson index, early mortality was significantly lower in patients treated with the AMULTEI strategy (AU)

Cirugía de la regurgitación tricuspídea grave: resultados a corto y largo plazo / Short- and long-term outcomes of surgery for severe tricuspid regurgitation

Introducción y objetivos. En nuestro medio hay pocos datos sobre los resultados del tratamiento quirúrgico de la insuficiencia tricuspídea grave. Nuestro objetivo es analizar los resultados clínicos y ecocardiográficos de nuestra población con insuficiencia tricuspídea grave sometida a cirugía comparándolos según el tipo de reparación o de sustitución valvular. Métodos. Realizamos un estudio retrospectivo incluyendo a 119 pacientes consecutivos con insuficiencia tricuspídea grave sometidos a cirugía de dicha válvula entre abril de 1996 y febrero de 2010. Resultados. Se realizaron 61 anuloplastias sin anillo y 23 con anillo, y se implantaron 11 prótesis biológicas y 24 mecánicas. La mortalidad perioperatoria fue del 18,5%, y se asociaron a ella la edad y el tiempo de circulación extracorpórea. Durante el seguimiento clínico (mediana, 41 [intervalo intercuartílico, 24-89] meses), el grupo anuloplastia con anillo precisó dos reoperaciones, al igual que el grupo de prótesis mecánica, en el que se diagnosticó trombosis protésica a 4 pacientes. La mortalidad total tras seguimiento fue del 29,9%, y se asociaron a ella la edad > 70 años y el tiempo de circulación extracorpórea. La aparición de nueva insuficiencia tricuspídea grave se asoció a la edad y la anuloplastia sin anillo (p = 0,04). Conclusiones. La reparación sin anillo se asoció significativamente con recurrencia de insuficiencia tricuspídea grave. El implante de prótesis mecánica se asoció a una elevada tasa de trombosis en el seguimiento. No se encontraron diferencias significativas en la mortalidad perioperatoria o total según el tipo de reparación o sustitución valvular (AU)

Introduction and objectives: There is little data available for Spain on the outcomes of surgical treatment for severe tricuspid regurgitation. The aim of this study was to analyze clinical and echocardiographic outcomes in a series of patients who received surgical treatment for severe tricuspid regurgitation and to compare outcomes according to the operative approach to valve repair or replacement. Methods: Retrospective study in 119 consecutive patients with severe tricuspid regurgitation undergoing valve surgery between April 1996 and February 2010. Results: A total of 61 ringless and 23 ring annuloplasties were performed and 11 bioprostheses and 24 mechanical prostheses were implanted. Perioperative mortality was 18.5% and was associated with age and cardiopulmonary bypass time. During clinical follow-up (median, 41 [interquartile range, 24-89] months), 2 reoperations were required in the ring annuloplasty and mechanical prosthesis groups; prosthetic thrombosis was diagnosed in 4 patients in the latter group. Total mortality after follow-up was 29.9% and was associated with age>70 years and extracorporeal circulation time. The emergence of new severe tricuspid regurgitation was associated with age and ringless annuloplasty (P=.04). Conclusions: Ringless repair was significantly associated with recurrence of severe tricuspid regurgitation. The use of mechanical prostheses was associated with a high rate of thrombosis. No significant differences in perioperative or total mortality were found between the different methods used for repair or valve replacement (AU)

Closure of perivalvular leaks using an Amplatzer occluder.

Reoperation of patients with perivalvular leaks due to heart failure or hemolysis is associated with increased morbidity and mortality. Percutaneous closure using an Amplatzer device offers a promising alternative. We describe our initial experience between 2004 and 2006, during which we used an Amplatzer device in eight patients for the percutaneous closure of perivalvular leaks (four aortic and four mitral). The patients were all symptomatic and had a high surgical risk. Device placement was successful in all patients with mitral leaks and in three with aortic leaks. There were no periprocedural complications. With four of the seven (57%) device placements, there was a significant reduction in the degree of regurgitation and, at 12-month follow-up, only these four patients showed clinical improvements. Of the other three, one required reoperation and two died of non-cardiovascular causes. Percutaneous closure of perivalvular leaks was feasible and safe and can be regarded as a treatment option in patients with a high surgical risk.

Utilización de los dispositivos Amplatzer para el cierre de fugas perivalvulares / Closure of perivalvular leaks using an amplatzer occluder

La reintervención de los pacientes con fugas perivalvulares por insuficiencia cardiaca o hemolisis está asociada a una elevada morbimortalidad. La utilización percutánea de los dispositivos Amplatzer supone una alternativa atractiva. Presentamos nuestra experiencia inicial: entre 2004 y 2006 realizamos cierre percutáneo con dispositivo Amplatzer a 8 pacientes con fugas perivalvulares (4 aórticas y 4 mitrales), sintomáticos y con alto riesgo quirúrgico. La implantación del dispositivo fue posible en todas las mitrales y en 3 aórticas. No hubo complicaciones durante el procedimiento. En 4 (57%) de los 7 implantes se logró una reducción significativa del grado de regurgitación y, tras 12 meses de seguimiento, solamente estos pacientes mejoraron clínicamente. De los 3 restantes, 1 paciente precisó reintervención y 2 fallecieron por causa no cardiovascular. El tratamiento percutáneo de las fugas perivalvulares es factible y seguro y puede considerarse como una opción terapéutica en subgrupos de alto riesgo quirúrgico (AU)
