ABSTRACT

BACKGROUND: To assess the efficacy and safety of intramyocardial autologous bone marrow mononuclear stem cells (BMMNC) grafting combined with coronary artery bypass grafting (CABG) on ventricular remodeling and global and regional wall motion after acute transmural myocardial infarction (AMI). METHODS: Randomized controlled trial including 20 patients with non-revascularized transmural AMI, left ventricular ejection fraction (LVEF) lower than 50% and surgical indication for CABG. The stem cell group was treated with BMMNC grafting by direct intramyocardial injection between the 10th and 15th days after AMI (subacute phase) combined with CABG under cardiopulmonary bypass; the control group was only treated with CABG. Magnetic resonance imaging with gadolinium and stress echocardiography were performed presurgery and 9 months postsurgery. RESULTS: Seventeen patients completed the follow-up. The baseline characteristics of both groups were homogeneous. No significant differences were found in the increase in LVEF (control: 6.99±4.60, cells: 7.47±6.61, P=0.876) or in the decrease in global (control: 0.28±0.39, cells: 0.22±0.28, P=0.759) or regional (control: 0.52±0.38, cells: 0.74±0.60, P=0.415) wall motion indices between the control and stem cell groups of AMI patients. No differences were found in the recovered non-viable segments (control: 1.29±1.11, cells: 2.50±1.41, P=0.091) or in the decrease in end-diastolic (control: 14.05±19.72, cells: 18.40±29.89, P=0.725) or end-systolic (control: 15.42±13.93, cells: 23.06±25.03, P=0.442) volumes. No complications from stem cell grafting were observed. CONCLUSIONS: The results from our study reported herein suggest that intramyocardial BMMNC administration during CABG in patients with AMI causes no medium- to long-term improvement in ventricular remodeling.

ABSTRACT

Coronary subclavian steal syndrome is an unusual cause of angina, secondary to decreased or reversed flow in patients with patent "in situ" internal mammary-to-coronary artery graft. The most frequent cause of coronary subclavian steal syndrome is ipsilateral subclavian artery stenosis. We present a 60-year-old man with cerebrovascular and peripheral artery disease and a documented massive coronary subclavian steal syndrome, which impaired cardiopulmonary bypass weaning after multiple coronary artery bypass with double T-mammary artery graft.

ABSTRACT

OBJECTIVES: Preoperative anemia has been related with adverse outcomes in elective valve replacement and CABG surgery. Impact of preoperative anemia on outcome in octogenarians submitted to cardiopulmonary bypass (CPB) has not yet been precisely described. METHODS: We analyzed association between preoperative hemoglobin level, minimum intraoperative and immediate postoperative hematocrit (HCT), and other co-morbidities and occurrence of adverse outcomes in 227 octogenarians who underwent cardiac surgery. RESULTS: Frequency of preoperative anemia was 41.9% (40.4% in male and 43.5% in female patients). Postoperative mortality was 13.2% (9% in non-anemic patients vs. 18.9% in anemic). 44.5% of patients suffered at least one postoperative adverse outcome (43.1% non-anemic vs. 46.3% anemic). In multivariate analysis (after adjusting independent preoperative risk factors for operative mortality and EuroSCORE) preoperative creatinine level [odds ratio (OR), 2.29; 95% confidence interval (CI), 1.06-4.98; P=0.035], immediate postoperative HCT <24% (OR, 2.78; 95% CI, 1.04-7.38; P=0.039), perioperative red blood cell (RBC) transfusion (OR, 1.58; 95% CI, 1.24-2.00; P=0.0001), peripheral vascular disease (OR, 4.92; 95% CI, 1.45-16.69; P=0.012) and urgent surgery (OR, 10.57; 95% CI, 2.54-43.91; P=0.0001) were identified as independent predictors for in-hospital mortality. CONCLUSIONS: Mortality and adverse postoperative outcome increase in anemic octogenarians undergoing cardiac surgery. Although mortality is directly related to immediate postoperative anemia, adverse outcomes mainly depend on associated co-morbidities.

ABSTRACT

La úlcera de Buruli, enfermedad hasta hace poco desconocida provocada por una micobacteria, M. ulcerans, ha experimentado en la última década importantes avances en su conocimiento. La enfermedad, endémica en muchos países africanos, supuso, durante tiempo, una dolencia dramática por la grave afectación y destrucción cutánea que provocaba antes de conocerse tratamiento válido para la misma. Actualmente, se han mejorado tanto los conocimientos sobre su etiología, posibilidad de vías de transmisión, patogenia, clínica y, sobre todo, tratamiento de la misma. A pesar de que en los países afectados en muchas ocasiones no existen estructuras sanitarias adecuadas para el control de estos pacientes, estos conocimientos y el apoyo de estructuras internacionales han permitido que el pronóstico de la enfermedad mejore considerablemente en todos sus aspectos. Este artículo intenta revisar los conocimientos actuales en cuanto a las diferentes facetas de esta enfermedad (AU)


Buruli ulcer until recently a practically unknown disease caused by a mycobacteria, Mycobacterium ulcerans, has experienced important scientific progress during this last decade that has significantly increased the knowledge of this disease. The disease is endemic in many African countries and was considered before the discovery of an effective treatment very stigmatizing due to its frequent disabling complications. At present, considerable advances have been accomplished in the fields of its etiology, modes of transmission, pathogenesis, clinical manifestations and treatment. Although many of the endemic countries lack the proper health systems and facilities for the control of the patients, the help of international organizations together with the new medical advances have improved the prognosis of this disease (AU)

ABSTRACT

Existe un creciente interés por realizar revascularizaciones miocárdicas y otras operaciones de cirugía cardíaca con el corazón latiendo, sin pinzamiento aórtico y siempre que sea posible sin el uso de la máquina de circulación extracorpórea (CEC), ya que se pueden obtener mejores resultados que los que se observan con las técnicas tradicionales de protección miocárdica con soluciones cardiopléjicas. Evaluar la seguridad, eficacia y los beneficios posoperatorios obtenidos en pacientes sometidos a la técnica de sustitución valvular mitral (SVM) con perfusión coronaria continua y el corazón latiendo, en relación con los operados mediante la técnica de SVM con parada cardíaca tradicional en el Instituto de Cardiología y Cirugía Cardiovascular, durante el período comprendido entre enero de 2001 y diciembre de 2002. Se diseñó un estudio de tipo prospectivo, controlado y aleatorizado, que fue sometido a evaluación y aprobación por el comité de ética de nuestra Institución, en el cual 64 pacientes de uno y otro sexos referidos a nuestro departamento para realizarles SVM aislada fueron seleccionados al azar para conformar dos grupos comparativos. Al grupo A se le realizó SVM mediante el método tradicional, y al grupo B se le realizó SVM con el corazón latiendo. La t de Student y el test de Wilcoxon Mann Whitney se utilizaron para comparar las medias de las variables cuantitativas estudiadas. En los pacientes del grupo B se observó una disminución de las concentraciones séricas de creatin-Kinasa total, creatin-kinasa MB y lactato, de las pérdidas totales de sangre y de la necesidad de transfusiones, del tiempo de soporte ventilatorio mecánico, de la estancia en el hospital y de la incidencia de complicaciones posoperatorias, entre otras variables, en relación con los pacientes del grupo A. La técnica quirúrgica evaluada constituye un método alternativo de protección miocárdica, seguro, eficaz y fácilmente reproducible, con el que se pueden alcanzar resultados... (AU)


A growing interest exists to carry out myocardial revascularisations and other beating heart surgeries, without aortic clamping and whenever it is possible without the use of the extracorporeal circulation machine (ECM), since it is possible to obtain better results than those observed with the traditional techniques of myocardial protection with cardioplegic solutions. To valuate the safety, effectiveness and the postoperative benefits obtained in patients undergoing the technique of mitral valve replacement (MVR) with continuous coronary perfusion and beating heart compared with those operated by the technique of MVR with traditional heart stop in the Institute of Cardiology and Cardiovascular Surgery between January 2001 and December 2002. A prospective, controlled and randomized study was designed and subjected to evaluation and approval by the committee of ethics of our Institution. i 64 patients of both sexes referred to our department for isolated MVR were selected at random and divided into two comparative groups. In the group A, MVR was performed by means of the traditional method, whereas in group B it was carried out with the heart beating. The Student's t test and Wilcoxon Mann Whitney's test were used to compare the means of the studied quantitative variables. In the patients of the group B, it was observed a decrease of the serum concentrations of total creatin-kinase, creatin-kinase, lactate, the total losses of blood, the need of transfusions, the time of mechanical ventilatory support, the stay in the hospital and the incidence of postoperative complications, among other variables, compared with the patients of group A. The evaluated surgical technique is an alternative method of myocardial protection, safe, effective and easily reproducible with which satisfactory clinical results can be attained(AU)

ABSTRACT

INTRODUCTION AND OBJECTIVES: Morbimortality related to cardiac surgery may be superior in patients with malignant neoplastic disease. Inflammatory phenomena and immunologic changes secondary to extracorporeal circulation use can also increase tumor recurrence. We evaluate characteristics and results of cardiac surgery in our neoplastic patients. METHODS: Out of 2146 consecutive patients who underwent cardiac surgery with extracorporeal circulation, 89 (4.2%) had been previously affected by cancer. Cancer was active (recent diagnosis or under treatment) in 33 patients (group A) and 56 (group B) were in remission. Both groups were matched with 165 patients with no tumor, according to age, gender, type of surgery, and comorbidity (group C). We retrospectively evaluated incremental risk factors for surgical morbimortality, survival and tumor recurrence. RESULTS: Median interval between cancer diagnosis and surgery was 60 months and mortality and morbidity were 4.5% and 36%, respectively, vs 5,4% and 32,7% in group C. During follow-up, 12 patients died (8 due to cancer), 16 suffered cancer recurrence and 2 new tumors were diagnosed. Statistical analysis did not permit us to identify any incremental risk factor for mortality. Postoperative morbidity was increased in case of preoperative renal failure. During follow-up, survival was significantly decreased in group A, in case of preoperative left ventricular dysfunction or pulmonary obstructive disease, and when interval between cancer diagnosis and cardiac surgery was under 2 years. CONCLUSIONS: We have not observed an increase in cardiac surgery morbimortality in cancer patients. Anyway, survival is decreased in case of active or recently diagnosed cancer.

ABSTRACT

Introducción y objetivos. La morbimortalidad de la cirugía cardiaca parece ser mayor en los pacientes neoplásicos. Los fenómenos inflamatorios y las reacciones inmunitarias secundarias a la circulación extracorpórea pueden favorecer la recidiva tumoral. Evaluamos las características y los resultados de la cirugía cardiaca en nuestros pacientes oncológicos. Métodos. De 2.146 pacientes consecutivos sometidos a circulación extracorpórea, 89 (4,2%) presentaban una neoplasia. El cáncer estaba activo (recientemente diagnosticado o en tratamiento) en 33 pacientes (grupo A) y en remisión completa en 56 (grupo B). Se pareó ambos grupos con 165 pacientes sin tumor similares en edad, sexo, tipo de cirugía y comorbilidad (grupo C). Evaluamos retrospectivamente los factores de riesgo de morbimortalidad quirúrgica, supervivencia y recidiva tumoral. Resultados. La mediana del intervalo entre diagnóstico del cáncer y cirugía fue de 60 meses, con mortalidad y morbilidad hospitalarias del 4,5 y el 36%, respectivamente, frente al 5,4 y el 32,7% en el grupo C. Durante el seguimiento, fallecieron 12 pacientes (8 por causa tumoral), 16 sufrieron recidiva y 2, tumores nuevos. El análisis estadístico no permitió identificar ningún factor de riesgo de mortalidad. La morbilidad postoperatoria aumentó en pacientes con insuficiencia renal. Durante el seguimiento, la supervivencia disminuyó significativamente en el grupo A en caso de disfunción ventricular izquierda preoperatoria y enfermedad pulmonar obstructiva crónica y cuando el intervalo entre diagnóstico de cáncer y cirugía fue < 2 años. Conclusiones. No hemos observado un incremento en la morbimortalidad de la cirugía cardiaca en pacientes oncológicos. No obstante, la supervivencia disminuye en neoplasias activas o de diagnóstico reciente

ABSTRACT

OBJECTIVES: To analyze the factors that influence outcomes of surgical myocardial revascularization in the female population. PATIENTS AND METHOD: This is a retrospective study in which 128 woman, subjected to GABC[IBM1] from January to September 2004, were enrolled in an univariate and multivariate analysis of risk factors associated with morbidity and mortality. RESULTS: The mean age was 69.19 +/- 9.05 [IBM2] years, the most frequent pathologies, comorbilities, were dyslipemia, hypertension, and myocardial infarction. Unestable angina was found in 63.28% patients and stenosis in the left main coronary artery 42.96%; NYHA III-IV in 23.43%. The EuroSCORE mean preoperative risk was [IBM3] 5.57. Twelve surgeries were emergencies. Mean of grafts was 2.57. Mortality corresponded to 5.4% in programmed surgeries, 7% global. Univariate analysis identified this risk factors releated to mortality (p < 0.05): age older than 67 years, NYHA III-IV and emergency surgery, complicated in 25.2%. Follow-up was kept in 90.8% of patients, mean follow-up time was 17.11 (+/- 14.94) months; 115 patients did not present angina. The risk factor for angina during follow-up, in the univariate analysis (p < 0.05) was not having used the left internal thoracic artery as graft for the anastomosis of the anterior descending artery. CONCLUSIONS: Emergency surgery, age older than 67 years, and NYHA III-IV, were independent risk factors associated with mortality in this group. The use of artery grafts associated to reduced angina during follow-up.

ABSTRACT

AIMS: Surgery in patients with infective endocarditis (IE) can be elective (upon completion of antibiotic treatment) or urgent (before antibiotic treatment has ended) when the clinical course is unfavourable. However, urgent surgery for left-sided endocarditis is associated with high mortality. The aims of this study were to describe the profile of patients with left-sided endocarditis who underwent urgent surgery and to analyse the factors that predicted mortality. METHODS AND RESULTS: Among 508 consecutive episodes of IE, 391 were left-sided and 89 required urgent surgery. The main reasons for urgent surgery were heart failure that did not respond to medication (72%) and persistent infection despite appropriate antibiotic treatment (31%). Thirty-two patients (36%) died during their hospital stay. Univariate analysis identified renal failure, septic shock, Gram-negative bacteria, persistent infection, and surgery for persistent infection as factors associated with mortality. Multivariate analysis confirmed only persistent infection and renal insufficiency as factors independently associated with a poor prognosis. CONCLUSION: Patients with IE who need urgent surgery have a poor clinical course. Heart failure, the main cause of urgent surgery, was not associated with higher mortality. However, persistent infection and renal failure were factors associated with higher post-surgical mortality.

ABSTRACT

Se presenta un caso de disección espontánea de la arteria coronaria descendente anterior en una mujer de 51 años, sin relación con factores desencadenantes conocidos. El inicio clínico fue un IAM no Q anterior, controlado con tratamiento médico y buena evolución clínica. El cateterismo cardíaco evidenció la disección de la arteria descendente anterior, que producía deterioro de la función sistólica. Se realizó revascularización arterial urgente mediante injerto de mamaria interna izquierda a descendente anterior sin CEC. El posoperatorio cursó sin complicaciones y a 25 meses del procedimiento la paciente se encuentra asintomática. Se realiza, además, una exposición de las consideraciones clínicas relacionadas con esta patología. (AU)

ABSTRACT

Se realizó un estudio cualitativo donde se exponen las características principales, objetivos de aplicación y las ventajas que ofrecen las diferentes soluciones coloidales y electrolíticas utilizadas en el cebado del circuito extracorpóreo. Como objetivo principal se exponen los argumentos necesarios que permiten al perfusionista combinar determinadas soluciones, para conservar la osmolaridad, la presión oncótica del plasma, mejorar el flujo microcirculatorio y evitar las transfusiones de sangre y hemoderivados innecesarias. También se mencionan diferentes técnicas para conservar el nivel del hematócrito, como son el uso de hemofiltros, concentrador de células y la aplicación de la cardioplejia sanguínea, que aunque su principal objetivo es la protección miocárdica, también sustituye los grandes volúmenes de líquido que caracteriza el uso de la cardioplejia cristaloide(AU)

The chief characteristics, objectives of application and the advantages the colloidal and electrolytic solutions used in the priming of the extracorporeal circuit offer are explained in this qualitative study. The necessary arguments that allow the perfusionist to combine certain solutions to conserve osmolarity, the oncotic pressure of plasma, to improve the microcirculatory flow and to avoid blood transfusions and unnecessary hemoderivatives, are dealt with as the fundamental aim. Reference is made to different techniques used to conserve the haematocrit level, such as: the use of haemofilters, cell concentrator and the application of blood cardioplegia, whose main goal is the myocardial protection, but it also substitutes the great volumes of fluid that characterize the use of crystalloid cardioplegia(AU)

2Se estudiaron los efectos de hemodilución extrema en 68 pacientes operados de cirugía cardíaca con derivación cardiopulmonar, así como las ventajas y complicaciones sobre diferentes factores, tales como diuresis, sangramiento posoperatorio, intercambio gaseoso y otras variables de interés que repercuten durante la fase evolutiva. La circulación extracorpórea se realizó con hipotermia moderada y elevado flujo sanguíneo, con cifras de hematócrito inferiores a 20 vol %. La saturación de oxígeno y presiones arterial y venosa, así como el equilibrio ácido-básico fueron normales. La diuresis resultó abundante durante la derivación cardiopulmonar (670 ñ 410 mL) y en el posoperatorio (2 020 ñ 770 mL), el sangramiento se mantuvo en rangos normales (351 ñ 137 mL) y en el posoperatorio (2 020 ñ 770 mL), el sangramiento se mantuvo en rangos normales (351 ñ 137 mL) y las variables de coagulograma recuperaron sus valores normales a las 24 h del posoperatorio inmediato. La evolución de los pacientes fue satisfactoria en el 90.5 % de los casos con resultados aceptables en cuanto a tiempo de recuperar la conciencia (2,6 ñ 1,38 h), intubación endotraqueal (10 ñ 5 h) y la estadía en la Unidad de Cuidados Intensivos Quirúrgicos (32 ñ 14h). Las complicaciones observadas fueron de origen multifactorial. El consumo de sangre, globulos y plasma homólogo se analizó en 5 años desde 1985 a 1989, lo que reflejó un volumen máxima de transfusiones de 3 540 unidades ($163 376) en 1987 y una reducción considerable de 777 unidades ($36 462) en 1989

ABSTRACT

Con el objetivo de caracterizar el patrón de variación de la CK-MB, se estudiaron 43 pacientes sometidos a revascularización coronaria en el Instituto de Cardiología y Cirugía Cardiovascular entre los meses de abril y noviembre de 1988, divididos en 3 categorias de acuerdo con criterios clínicos y electrocardiográficos; grupo 1, sin infarto del miocardio perioperatorio (IMPO) (28), grupo 2, con infarto probable (8) y grupo 3, con IMPO (7). La actividad catalítica de CK-MB se midió por el método inmunológico seriadamente desde el período preperfusión hasta la segunda mañana del posoperatorio, previa discriminación con análisis de CK sérica. Para el análisis estadístico se utilizaron el Anova de una sola entrada la prueba t de Student para muestras independientes. Los pacientes con IMPO se diferenciaron significativamente de los del grupo 1 (p<0,001) desde las 6 horas de su llegada a la Unidad de Cuidados Intensivos Quirúrgicos. No hubo diferencias significativas entre los grupos 1 y 2. Se concluye que la CK-MB es una prueba valiosa para detectar infarto perioperatorio de la cirugía revascularizadora coronaria

ABSTRACT

Se estudiaron 25 pacientes de ambos sexos, sometidos a cirugía cardiovascular con derivación cardiopulmonar, con el objetivo de conocer las variaciones de los niveles de inmunoglobulinas, proteínas y leucocitos, en diferentes tiempos de muestreos: el preoperatorio (A), al término de la derivación cardiopulmonar (B) y a las 48 horas de posoperatorio (C). También se analizaron los casos sépticos y su relación con los efectos deletéreos de la circulación extracorpórea. El estudio inmunológico reportó una disminución (cualitativa) de los niveles plasmáticos de inmunoglobulinas al término de la derivación cardiopulmonar. El análisis comparativo de las proteínas arrojó diferencias estadísticamente significativas (p<0,001) cuando comparamos los tres tiempos de muestreo; se encontró una disminución de sus niveles plasmáticos al final de la derivación cardiopulmonar (B), comparado con los muestreos A y C. Los leucocitos se compararon exclusivamente entre los tiempos de muestreos A y C y se incrementaron significativamente sus niveles a las 48 horas de posoperatorio (p<0,001) con valores promedios de 8,03 ñ 1,81 a 11,35 ñ 3,6 (10 L). En el 54


de los casos se observó leucocitosis. En dos pacientes se presentó sepsis superficial y tardía en la herida quirúrgica, la cual no estuvo relacionada con los efectos deletéreos de la circulación extracorpórea. No se observaron casos con endocarditis bacteriana, con lo cual quedó descartada su posible relación con las alteraciones del mecanismo defensivo durante el período de derivación cardiopulmonar. Es importante destacar que en un período de 48 horas se logra una recuperación normal de las inmunoglobulinas y del sistema defensivo en los pacientes estudiados
