ABSTRACT

Se estableció la puntuación Syntax como herramienta para determinar la complejidad de la enfermedad coronaria y como guía para tomar decisiones entre la cirugía de revascularización coronaria y el intervencionismo coronario percutáneo. El propósito de esta revisión es examinar de manera sistemática qué es la puntuación Syntax, cómo el cirujano debe integrar la información en la selección y tratamiento del paciente. Revisamos los resultados del estudio SYNTAX, las guías de práctica clínica, así como los beneficios y las limitaciones de la puntuación. Finalmente, el rumbo hacia el futuro que tomará la puntuación Syntax.


The Syntax score has been established as a tool to determine the complexity of coronary artery disease and as a guide for decision-making among coronary artery bypass surgery and percutaneous coronary intervention. The purpose of this review is to systematically examine what the Syntax score is, and how the surgeon should integrate the information in the selection and treatment of patients. We reviewed the results of the SYNTAX Trial, the clinical practice guidelines, as well as the benefits and limitations of the score. Finally we discuss the future directions of the Syntax score.

ABSTRACT

UNLABELLED: Homocysteine is implicated as an early atherosclerotic promoter, which enhances the smooth muscle cell proliferation and produces free radicals that induce cellular damage. These factors must have a role in the progression of atherosclerosis that subsequently leads to vascular mineralization. AIM: Identify a correlation between the plasma concentration of total homocysteine and the amount of minerals that accumulate in the aorta of patients with atherosclerosis. METHODS: We performed a cross-sectional study in 13 patients with three-vessel coronary artery disease, undergoing coronary artery bypass surgery. Aortic and mammary artery specimens were analyzed using a scanning electron microscope with an energy dispersive X-ray spectrometer. The homocysteine was determined using an immunonephelometry method. RESULTS: The amount of minerals in the aorta was greater (300 ± 181.6 particles per 500 µm2 than that in the mammary artery (64 ± 45 particles per 500 µm2 (p < 0.01). The average tHcy was 9.5 ± 2.3 µmol/L. The Spearman's rank correlation coefficient was positive between tHcy, and aortic iron (p < 0.05). CONCLUSIONS: Our study demonstrates that the aorta is dramatically affected by mineralization compared to the mammary artery. In addition, a direct correlation was identified between the levels of tHcy and the iron particles in the aortic wall.

ABSTRACT

BACKGROUND: In 1999 so as to decrease the list of cardiac surgery the "fast track" program was started for patients with very mortality low risk. In 2004, this program was extended to moderate risk patients. OBJECTIVES: A prospective, descriptive study to evaluate the clinical and demographic characteristics of "fast track" program patients for elective cardiac surgery. We also analyzed the hospital stay, mortality, complications and readmissions. METHODS: From March 2004 to February we included adult patients with indications for cardiac surgery, low to intermediate risk of mortality and complete preoperative requirements. RESULTS: From a total of 598 patients, 533 were analyzed, aged 47±14 years, 62.5% female. They were classified in four groups: valvular (68%), congenital (25%), coronary artery disease (5%), and mixed (2%). The average hospital stay was: preoperative 1.9, intensive care unit three, postoperative in hospitalization 6.9 and total 11.9 days. We found that 17.8% had a hospital stay longer than 14 days due to: reoperations, pulmonary complications, arrhythmias or infections. The mortality was 4.1 and 2.8% had readmissions three months after surgery. CONCLUSIONS: This program shows a low rate of mortality, hospital stay and readmissions."

ABSTRACT

Introducción: Para disminuir la lista de espera para la cirugía cardiaca electiva, en 1999 el Instituto Nacional de Cardiología Ignacio Chávez inició un programa de vía rápida para casos de muy bajo riesgo quirúrgico. En 2004, este programa se extendió a pacientes con riesgo intermedio. Objetivos: Estudio prospectivo, descriptivo, para evaluar las características clínicas y demográficas de los pacientes del programa de vía rápida en cirugía cardiaca electiva. También se analizaron la estancia hospitalaria, mortalidad, complicaciones y reingresos. Métodos: De marzo de 2004 a febrero de 2009 incluimos pacientes adultos con indicación de cirugía cardiaca y con riesgo quirúrgico de bajo a intermedio, con requisitos preoperatorios completos antes del internamiento. Resultados: De un total de 598 pacientes ingresados al programa, se analizaron 533, con edad de 47 ± 14 años, 62.5% mujeres. Se clasificaron en cuatro grupos: valvulares (68%), congénitos (25%), isquémicos (5%) y mixtos (2%). Los promedios de días de estancia hospitalaria fueron: preoperatoria 1.9, terapia tres, postoperatoria en piso 6.9 y total 11.9 días. Se evidenció que 17.8 % estuvieron más de 14 días por: reoperaciones, complicaciones pulmonares, arritmias, o infecciones. La mortalidad fue de 4.1% y hubo 2.8% de reingresos en los primeros tres meses posteriores a la cirugía. Conclusiones: Este programa conduce a bajos índices de mortalidad, estancia hospitalaria y reingresos.

ABSTRACT

Cardiac transplantation is a well defined therapy for end stage heart failure. After the first year of transplantation, allograft coronary artery disease (ACAD) is the second main cause of death. The ACAD is defined as a diffuse process affecting the entire length of epicardial vessels. Once ACAD has been established, treatments such as coronary angioplasty, coronary stenting, and coronary bypass are performed. We present a case of successful stenting of the left main coronary artery (LMCA) in a patient with ACAD. The patient's medical history was significant for heart transplantation due to ischemic heart failure. Four years after transplantation the patient was admitted again due to sudden worsening of New York Heart Association functional class and extreme fatigue. Coronary angiogram showed a severe stenosis in the proximal segment of the LMCA; we performed stenting with a paclitaxel-eluting stent (PES). Six months after the procedure, the patient had an elective angiogram, where we discovered a new severe occlusion distally to the former stent; a second PES was implanted. Fourteen months after the second stenting, a new elective angiogram was performed without evidence of in-stent restenosis. After a 8-year follow-up since transplantation, the patient is free from dyspnea, angina, and adverse cardiovascular events. Our report suggests the efficacy of PES as ACAD treatment of the unprotected LMCA.

ABSTRACT

The actual therapeutic guidelines, look to conceive reperfusion of the infarcted myocardial areas in less time with pharmacological treatment, interventionist procedures or surgery for revascularization. CABG should be consider as a therapeutic modality that can be use for the treatment of cardiogenic shock, in well selected patients, as in those who primary angioplasty could not be achieved as treatment for the acute myocardial infarction. We revised the patients characteristics, the useful modalities and benefits that CABG can offer in this pathology.

ABSTRACT

OBJECTIVE: To determine the main factors for perioperative mediastinal bleeding during coronary artery by-pass grafting and to establish the role of acetylsalicylic acid, other inhibitors of platelet adhesion, and anticoagulants in its occurrence. METHODS: A multivariate analysis was performed to the data obtained from 251 patients subjected to coronary artery by-pass grafting in the year 2002. RESULTS: There were no significant differences for the occurrence of perioperative bleeding induced by the preoperative administration of acetylsalicylic acid. No significant increment in the need for blood, platelet, or cryoprecipitates transfusion existed. Patients receiving non-fractionated or low molecular weight heparin had a significantly greater (p < 0.001) transoperative bleeding than patients without this drug. Administration of the other studied drugs did not increase either mediastinal bleeding or the need for blood derivatives. CONCLUSIONS: No statistical evidence was found to suspend administration of inhibitors of platelet adhesion in patients with coronary syndromes, subjected to coronary artery by-pass grafting. However, data obtained suggest the convenience of suspending administration of low molecular weight or non-fractionated heparin to patients subjected electively to coronary artery by-pass grafting.

ABSTRACT

Propósito del trabajo: Determinar los factores predisponentes para sangrados perioperatorios en cirugía de revascularización miocárdica y establecer el papel de ácido acetilsalicílico, otros antiagregantes plaquetarios, y anticoagulantes, en la ocurrencia de estos sangrados. Método: Se realizó un análisis multivariado de 251 pacientes sometidos a cirugía de revascularización miocárdica en el año 2002. Resultados: En la administración prequirúrgica de ácido acetilsalicílico no se encontró diferencia significativa para la ocurrencia de sangrado perioperatorio importante. No existió incremento significativo en la transfusión de unidades de paquetes globulares, plaquetas, crioprecipitados. Los pacientes con administración de heparina no fraccionada y de bajo peso molecular, tuvieron un sangrado transoperatorio significativamente mayor (p < 0.001) que los pacientes sin este fármaco. El empleo del resto de los fármacos estudiados, no incrementó la cantidad de sangrado ni la administración de hemoderivados. Conclusiones: No existe evidencia estadística que justifique suspender la administración de antiagregantes plaquetarios en los pacientes con síndromes coronarios urgentes o electivos, a quienes se les someta a cirugía de revascularización miocárdica. Sin embargo, resultaría conveniente suspender la administración de heparina no fraccionada y de bajo peso molecular, a pacientes sometidos a cirugía de revascularización miocárdica en forma electiva.

ABSTRACT

Los síndromes coronarios agudos, la angina inestable y el infarto del miocardio sin elevación del segmento S-T, continúan siendo manifestaciones comunes de la enfermedad coronaria. La diferencia entre ambas entidades es la severidad de los síntomas, fundamentalmente manifestada por la presencia de la elevación de troponinas como marcadores bioquímicos de necrosis miocárdica. Estos síndromes coronarios agudos requieren en primera instancia un tratamiento médico agresivo que logre estabilizar los síntomas anginosos. La cirugía de revascularización coronaria tiene una indicación similar a la fecha, derivada de las lesiones obstructivas coronarias; todas ellas catalogadas como de alto riesgo.

ABSTRACT

Se revisa la literatura de las heridas cardiacas. Aún en el siglo XIX, época caracterizada por el gran desarrollo de la cirugía, e inicio de los grandes descubrimientos no sólo de anatomía y fisiología, sino también de la ligadura de vasos sanguíneos, de la anestesia, asepsia y antisepsia, los grandes cirujanos pensaban que estas heridas eran el límite de lo que el hombre podía hacer con la cirugía.Se comenta el caso de un paciente que dos años antes sufrió una herida por proyectil de arma de fuego sobre el área cardiaca y que ahora recibió 3 heridas por arma punzocortante en el mismo sitio, las cuales, le lesionaron las 4 válvulas y le produjeron fístulas entre la aorta y la pulmonar y entre esta y el ventrículo izquierdo. El paciente fue operado con éxito, reparando las lesiones valvulares y cerrando las fístulas sin tener que sustituir ninguna válvula y dado de alta en buenas condiciones.

ABSTRACT

De enero 1980 a diciembre de 1992 se trataron quirúrgicamente, con procedimientos conservadores, 400 valvulopatías mitrales: 364 de origen reumático, 33 congénitos y 3 posiblemente mixomatosos. La clase funcional y la cardiomegalia, era para la mayoría de ellos III y IV, con hipertensión pulmonar. Se realizaron diferentes procedimientos, el más común la comisurotomía de una o ambas comisuras; la apertura del aparato subvalvular; la colocación de anillo y un nuevo procedimiento llamado "Punto de tensión". Los resultados fueron muy buenos; con frecuencia baja de reoperación de 9.2 por ciento, causada generalmente por reestinosis por fibrosis o que provocó disfunción. Otra causa, la dificultad fue de 2 por ciento, no debida al procedimiento, sino en general a la mala condición clínica de los pacientes. El seguimiento está por arriba de los 13 años, con una curva actuarial de sobre vida de 98 por ciento, con 90.8 por ciento libres de reoperación y una muy buena calidad de vida. Este análisis constituye un esfuerzo por atraer la atención de los cirujanos, ya que estos procedimientos son una alternativa a la colocación de prótesis en pacientes que por diversas razones no deben recibirla, puesto que no están exentas de múltiples complicaciones

ABSTRACT

Dadas las características del aumento de longevidad en la población actual, las posibilidades de llegar a someterse a una cirugía de revascularización coronaria son cada vez mayores. En forma rutinaria se ha llegado a considerar que a los enfermos octogenarios sujetos a revascularización coronaria no se les debe colocar injertos arteriales, ya que ello acarrea mayor riesgo perioperatorio, y la longevidad esperada no justifica su uso. Realizamos una revisión retrospectiva de doce años de nuestra experiencia, con un total de 148 enfermos mayores de 70 años a los que se les colocó al menos un hemoducto de arteria mamaria interna. Obtuvimos una mortalidad de 3.37 por ciento, sin observar un aumento en las complicaciones perioperatorias como lo son la mediastinitis o el sangrado posoperatorio. Con estos resultados consideramos que la edad per se no debe considerarse una contraindicación para el empleo de la arteria mamaria interna como hemoducto coronario

ABSTRACT

Es bien conocida la complicación de ruptura del espesor completo del ventrículo izquierdo, consecutivo a cambio valvular mitral, la cual ha sido ampliamente clasificada en cuanto a su localización, tratamiento y pronóstico. Sin embargo, existe la laceración incompleta, la cual se manifiesta por disfunción ventricular izquierda severa en el posoperatorio, y dicha complicación ha sido pobremente reportada. Con las actuales téncicas operatorias, la presentación de la ruptura ha disminuido, lo que probablemente traiga consigo un aumento equiparable en la frecuencia de presentación de la laceración incompleta. Describimos un caso de laceración incompleta y de su tratamiento agresivo. Realizamos también una revisión de la literatura acerca del tema

ABSTRACT

Ha sido evidente en la última década el aumento en la cantidad de enfermos octogenarios que son llevados a cirugía cardiaca; sin embargo, la edad avanzada desde siempre se ha considerado como un factor de riesgo adicional. En esta revisión se analiza la serie reciente de nuestros enfermos octogenarios llevados a cirugía de revascularización miocárdica, así como la morbi-mortalidad de estos enfermos comparativamente con un grupo equiparable de enfermos de menor edad. Se concluye que estos enfermos son susceptibles de ser tratados mediante cirugía sin un mayor riesgo, aún cuando se empleen hemoductos arteriales, siendo el beneficio mayor que mediante tratamiento médico.
