ABSTRACT

Introducción: La estenosis aórtica fibrocálcica es el tipo de valvulopatía más frecuente, especialmente en los adultos mayores, siendo el reemplazo valvular aórtico el tratamiento definitivo. Un mal resultado post operatorio puede deberse a un mal funcionamiento de la válvula protésica. Caso clínico: Paciente de 42 años de edad sometido a reemplazo valvular aórtico por presentar estenosis aórtica severa fibrocálcica en una válvula bicúspide y aorta de pared muy fina. Evoluciona asintomático durante 4 años, al cabo de los cuales y luego de abandonar su tratamiento anticoagulante consulta por disnea y dolor anginoso. Un ecocardiograma muestra estenosis severa de la válvula protésica. Dado los antecedentes de su cirugía previa se decide implantar un conducto de dacrón valvulado ápico-aórtico a través de toracotomía posterolateral izquierda. Evolución post operatoria muy satisfactoria permaneciendo asintomático, con un seguimiento de 15 meses. La recidiva de la estenosis aórtica severa post reemplazo valvular protésico tiene en el bypass ápico-aórtico una excelente alternativa de tratamiento efectivo, especialmente cuando el recambio valvular tradicional implica un alto riesgo quirúrgico.


Introduction: The most frequent surgical procedure of severe left ventricular outflow tract obstruction due to severe aortic stenosis is aortic valve replacement, but there is an alternative and less conventional method described by Cooley used in patients with previous aortic valve replacement and severe aortic wall calcification that bypasses the left ventricular outflow tract through the implant of an apicoaortic valved conduit. Clinical case: We describe the case of 42 years old patient with severe aortic stenosis due to mismatched valve prosthesis previously installed treated by of apicoaortic conduit implanted through left posterolateral thoracotomy.

ABSTRACT

We report a 30 year old female admitted with a story of right upper quadrant pain and previous hepatic surgery for hydatid disease. A thoracoabdominal angio CAT sean and transesophageal echocardiogram revealed a mass located in the right atrium. The patient was operated and the right atrial mass was excised. Pathological study of the surgical piece confirmed a hydatid cyst. Post operative recovery was uneventful.


La hidatidosis es una zoonosis parasitaria, de mayor incidencia en el sur de Chile. Su localización más frecuente es hepática y pulmonar. Sus complicaciones derivan de su crecimiento y afección de estructuras adyacentes o de su ruptura a cavidades. Presentamos un caso de quiste hidatídico hepático complicado, en una paciente que debutó con cuadro de dolor abdominal localizado en hipocondrio derecho producto de una lesión quística hepática con comunicación a vena cava inferior, siendo intervenida en su hospital de origen. Posteriormente AngioTAC y ecocardiografía transesofágica confirmaron masa intra auricular. Se realizó extracción de la masa bajo paro circulatorio con hipotermia profunda, correspondía a membranas hidatídicas y trombos adheridos a ella. La paciente evolucionó satisfactoriamente.

ABSTRACT

Background: In recent years the use of left internal mammary artery (LIMA) as a gran to anterior descending artery (DA) with the offpump technique has been associated with similar good long term results as with the on pump technique. Aún: To repon the results of LIMA to DA bypass grafting without extracorporeal circulation (EC) for isolated DA lesions. Patients and methods: Descriptive study of 80 patients subjected to coronary surgery between 1999 and 2007. Results: Mean age ofpatients was 63 + 10 years and 60 were male. There was no operative mortality or stroke. One patient with a myocardial infarction required a reoperation. Actuarial survival was 98% at 97 months. Conclusions: In this group ofpatients the use ofLIMA as a coronary bypass gran to DA with the off pump technique is a safe surgical procedure, providing a prolonged cardiac event free survival (mortality, angina, myocardial infarction, and need for a new coronary procedure).

ABSTRACT

Los tumores cardíacos son una causa rara de accidente cerebrovascular embólico. Comunicamos el caso de una paciente de 65 años quien debuta su historia con un accidente cerebrovascular. El estudio de fuente embólica con ecocardiografía transesofágica demostró un fibroelastoma de la válvula aórtica en el borde libre del velo no coronariano. El tumor fue extraído mediante circulación extracorpórea. El estudio anatomopatológico confirmó el diagnóstico y la paciente se encuentra en capacidad funcional I y sin síntomas neurológicos a 19 meses de seguimiento.


Background: Cardiac tumors are an infrequent cause of an embolic source and aortic fibroelastoma is even more rare as causative of a stroke. We report a 65 year old female with no particular clinical history admitted to the hospital with an embolic cerebrovascular accident whose embolic source study with a transesophageal echocardiogram revealed a fibroelastoma in the free edge of the non coronarian leaflet of the aortic valve. The patient was subjected to surgery by means of extracorporeal circulation and the tumor was excised. The pathological study confirmed the diagnosis. Post operative recovery was uneventful with no neurological damage and after 19 months of follow up she is in functional class I.

ABSTRACT

Background: Aortic valve surgery can be performed through a reduced mid sternotomy with excellent long term results. Aim: To report the initial results obtained with this technique. Patients and methods: Descriptive study of 20 patients aged 48±11 years, subjected to valve replacement surgery for aortic valve disease between 2004 and 2007. Arterial and venous cannulation were performed with the usual method and extracorporeal circulation was performed with a mean perfusion of 4.5 L/min. Hypothermia and cardioplegia were performed infusing the hematic cardioplegic solution at 4°C in the aortic root or coronary ostia. Results: Sixteen patients were in functional class (FC) III. Fourteen patients had aortic insufficieney and six had predominant stenosis. There was no operative mortality One patient had a left hemothorax and was reoperated. All patients were discharged between 4 and 6 days after surgery. Mean follow up was 21 ± 4 months. AU patients are in FC I and free from cardiac events. Echocardiographic assessment was done in 16 patients, showing a good motility of valve disks. Actuarial survival probability was 100 percent and probability of freedom from cardiac events was 100 percent at 42 months of follow up. Conclusions: Ministernotomy is an excellent approach for aortic valve surgery providing good visualization ofthe ascending aorta, simplifying the surgical technique.

ABSTRACT

La Endocarditis Infecciosa (El) es una enfermedad grave, dada por la agresividad del agente sobre el aparato cardiovascular y otros órganos. La cirugía de reemplazo valvular (CRV) es el tratamiento definitivo frente al fracaso del tratamiento médico, la cual está asociada a una elevada mortalidad al presentarse con daño estructural severo. Objetivo: Evaluar los factores asociados a mortalidad en pacientes sometidos a CRV por El. Pacientes y método: Estudio descriptivo de 32 pacientes consecutivos sometidos a CRV en el período 1993-2005, consignando antecedentes clínicos que determinen una probable mortalidad. Resultados: La mortalidad global fue de 25 por ciento, principalmente en los primeros 15 días (60 por ciento). Los principales factores asociados son sepsis (p =0.002), la cirugía mitro-aórtica (p <0.001) y la presencia de alcoholismo (p =0.049). La probabilidad de supervivencia actuarial es de 78 por ciento a 146 meses. Conclusión: La mortalidad de nuestra serie es semejante a otros centros, existiendo un mayor riesgo en los primeros días post CRV. El reemplazo bivalvular y la presencia de sepsis son los principales factores de riesgo precoz.


Infectious endocarditis is a severe illness related to the aggressiveness of the microbial agent to the cardiovascular system. Heart valve replacement surgery is the definitive treatment in these patients but is related to high mortality when the structural damage is severe. Objective: To assess risk factors related to mortality in patients operated for complicated endocarditis. Patients and method: Descriptive study of 32 patients operated between 1993-2005 period in which clinical factors were evaluated and related to mortality. Results: Overall mortality was 25 percent, mainly in the first two weeks after surgery (60 percent). Mortality related risk factors were sepsis (p =0.002), mitro-aortic replacement (p <0.001) and alcoholism (p =0.049). Actuarial survival probability is 78 percent to 146 months in the group. Conclusion: Mortality is similar to others cardiac centres and is higher in the first two weeks alter surgery. Mitro aortic replacement and sepsis are the main factors of early mortality risk.

ABSTRACT

Background: Surgery for active endocarditis is indicated in cases of congestive heart failure (CHF), persistent sepsis, systemic embolization and paravalvular involvement. Aim: To assess and report the long term results of surgery in adult patients. Patients and methods: Retrospective review of clinical records and operative procedures of 32 patients aged 43± 13 years (28 women) subjected to reparative surgery for complications of endocarditis between 1993 to 2005. Results: In 25 percent of cases, endocarditis presented as a prolonged sepsis syndrome and in 31 percent as a CHF or both. The causative bacteria was Gram (+) in 53 percent and blood cultures were negative in 47 percent. Preoperative echocardiography showed vegetations in 56 percent of cases. An annular abscess, aortic valve rupture and bicuspid valve, was observed in 13 percent of patients. Post operative mortality was due to persistent sepsis and multiorganic dysfunction in 16 percent. Mean long term follow up was 43.8±47.2 months. Actuarial survival was 78 percent at 146 months. Conclusion: Surgical management of active endocarditis provides a good symptomatic recovery, with an excellent long term actuarial survival.

ABSTRACT

En años recientes el uso de arteria mamaria interna izquierda (LIMA) como injerto a la arteria descendente anterior (DA) sin circulación extracorpórea (CEC) ha demostrado resultados similares a la técnica convencional. Objetivo: Comparar y comunicar los resultados obtenidos con el uso de LIMA a DA con y sin CEC en lesiones aisladas de la DA. Material y método: Estudio descriptivo de 85 pacientes en quienes se realizó cirugía coronaria entre 1992 y 2004. Resultados: Edad promedio fue 62.5 años (DE + 9.575, rango 35-77 años), 59 de sexo masculino; el test de ANOVA no demostró diferencias entre los grupos en relación a factores de riesgo preoperatorios, características angiográficas y presentación clínica. 40 pacientes fueron operados con CEC y 45 sin CEC. El tiempo quirúrgico promedio y en ventilador mecánico fue mas corto para el grupo sin CEC (p<0.005). No hubo mortalidad operatoria, infarto miocárdico, accidente cerebrovascular o necesidad de reoperación en el grupo con CEC. Se realizó una reoperación en 1 paciente sin CEC. En el seguimiento hubo 2 muertes alejadas debido a falla cardiaca y renal avanzadas en el grupo con CEC y ninguna en el grupo sin CEC. La probabilidad de sobrevida actuarial fue 96 por ciento a 139 meses en el grupo con CEC y 98 por ciento a 64 meses en el grupo sin CEC. Conclusiones: En este grupo de pacientes el uso de LIMA como injerto a la DA con ambas técnicas es un procedimiento seguro, el que provee un tiempo prolongado libre de eventos como mortalidad, angina, infarto miocárdico y necesidad de un nuevo procedimiento coronario en el seguimiento a largo plazo.

Aim: To compare and report the results of LIMA to DA bypass grafting with and without extracorporeal circulation (EC) for isolated DA lesions. Patients and methods: Descriptive study of 85 patients subjected to coronary surgery between 1992 and 2004. Results: Mean age was 62.5 years (DE+9.575, range 35-77 years), 59 were male, ANOVAtest showed no differences between groups related to preoperative risk factors, angiographic characteristics and clinical presentation. 40 patients were operated on pump and 45 off pump. Mean operative time and time in mechanical ventilator were shorter for the off pump group (p<0.005). There was no operative mortality, myocardial infarction, stroke or need of a reoperation in the on pump group. There was a reoperation in 1 patient in the off pump group. In the follow up there were 2 late deaths because of advanced cardiac and chronic renal failure in the on pump group and none in the off pump group. Actuarial survival probability was 96 percent at 139 months in the on pump group and 98 percent at 64 months in the off pump group. Conclusions: In this group of patients the use of LIMA as a coronary bypass graft to DA with both techniques is a safe surgical procedure, providing a prolonged time free from cardiac events as mortality, angina, myocardial infarction, and need of a new coronary procedure in the long term follow up.

ABSTRACT

Background: The use of left internal mammary artery (LIMA) as a graft to anterior descending artery (LAD) has been associated with better long term results in coronary surgery. Aim: To assess and report the long-term results of LIMA to LAD bypass grafting for isolated LDA lesions. Patients and methods: Retrospective analysis of the medical records and surgical protocols of 40 patients (aged 60±10 years, 28 male) subjected to coronary surgery between 1992 and 2002. Results: Thirty-four patients presented with unstable angina. On angiography, the LAD had a proximal obstruction in 35 patients. Sixteen presented with a myocardial infarction of the LAD territory. Six were managed previously with angioplasty; four had a new critical obstruction, 1 was catalogued as a procedure failure, and one was totally occluded. There was no operative mortality, myocardial infarction, stroke or need for re operation. There were two late deaths, caused by an advanced cardiac failure at 120 months in one patient, and chronic renal failure at 61 months of follow-up in another. Actuarial survival probability was 100%, 93% and 75% at 1, 5 and 10 years. Probability of freedom from angina was 98%, and freedom of suffering a new myocardial infarction was 100% at more than 10 years. The probability of no need for a new coronary procedure (angioplasty or surgery) also was 100% at more than 10 years. Conclusions: The use of LIMA as a coronary bypass graft to LAD is a safe surgical technique, with an excellent duration and permeability and also provides a prolonged time free from cardiac events as mortality, angina, myocardial infarction, and the need of a new coronary procedure.

ABSTRACT

La hidatidosis cardíaca tiene una incidencia de 0.5 a 2 por ciento, siendo la ubicación pericárdica la más frecuente. En los últimos años en nuestro hospital se han presentado 2 casos de hidatidosis intracardíaca (HI). Primer caso: varón de 15 años con diagnóstico de muerte súbita mientras realizaba ejercicio. La autopsia demostró un QH roto en músculo papilar de ventrículo izquierdo (VI). Segundo caso: mujer de 26 años con antecedente de cirugía por hidatidosis hepática. Ingresa a UCI por taquicardia supraventricular. El estudio por imágenes mostró tumor quístico intracavitario en pared inferolateral de VI. Las pruebas serológicas para hidatidosis fueron positivas. Se efectúa cirugía en julio de 1998, a través de esternotomía media bajo circulación extracorpórea, hipotermia y cardioplejía, practicándose quistectomía más capitonaje de la pared VI. La evolución postoperatoria fue favorable, no hubo complicaciones, siendo dada de alta al 8º día. El tratamiento de la HI debe ser quirúrgico con buenos resultados

ABSTRACT

Se presentan 12 casos, de un total de 164 traumatismos vasculares, en 118 pacientes con una fístula arteriovenosa traumática (FAVT) (7,3%), entre enero de 1980 y diciembre 1987. Nueve correspondieron a heridas por bala y tres a yatrogenia, todas ubicadas en las extremidades. La totalidad se manifestaron en forma tardía, presentaban soplo y la mitad insuficiencia cardiaca. Tras angiografías fueron sometidas a reparación quirúgica, con resultados excelentes en 11 casos; uno fue inabordable por lo que se efectuaron ligaduras distales y proximales, con reaparición posteriormente de la sintomatología en forma más atenuada

ABSTRACT

En este trabajo, presentamos la experiencia del Equipo de Cirugía Vascular del Hospital Regional de Temuco durante los últimos 5 años, en este lapso, fueron ingresados 65 pacientes portadores de 90 lesiones vasculares. Los vasos más frecuentemente comprometidos, fueron las aterias femoral y poplítea; el agente etiológico más comúm fueron los traumatismos abiertos, principalmente secundarios a heridas por arma blanca y de fuego; la desición sobre la intervención quirúrgica, fue basada preferentemente en hechos clínicos debido a la falta de disponibilidad inmediata de la angiografía en casos de urgencia. Los procedimientos terapéuticos más frecuentemente empleados , fueron el uso de un trozo de vena safena interna como injerto, la simple sutura de la lesión y la anastomosis T-T, luego de acondicionar los cabos vasculares. Del total de pacientes intervenidos, fue necesario amputar la extremidad, luego de intentarse la reparación en 5 pacientes, lo que representa una cifra de 11,3% de pérdida de extremidad
