Comparison of six percent hydroxyethyl starch 130/0.4 and ringer's lactate as priming solutions in patients undergoing isolated open heart valve surgery: A double-blind randomized controlled trial.

OBJECTIVES: Colloids are added to the priming solution of the cardiopulmonary bypass (CPB) pump to maintain colloid osmotic pressure and prevent fluid overload. This study aimed to compare the effects of 6% hydroxyethyl starch (HES) 130/0.4 and ringer's lactate (RL) priming solution on patients' outcomes undergoing isolated heart valve surgery with CPB. METHODS: This randomized clinical trial included one hundred and 20 patients undergoing heart valve surgery, and those were allocated into two groups. Patients in the RL group received 1500 mL of RL, and those in the RL + HES group were given 500 mL of HES and 1000 mL of RL. RESULTS: The patients' median age was 52 (IQR 42-60) and 50 (IQR 40-61) years in the RL + HES and the RL group, respectively (p = .71). The number of cases that required blood product transfusion in both the operating room and intensive care unit was also significantly higher in the RL + HES group compared to the RL group (RR 2.04, 95% CI 1.50-2.76; p < .01 and RR 1.42, 95% CI 1.01-2.01; p = .05, respectively). Declines in postoperative creatinine levels and platelet counts were higher in the RL + HES compared to the RL group (between-subjects effect p = .007 and p = .038, respectively), while the incidence of acute kidney injury was comparable between groups (RR 0.66, 95% CI 0.13-3.30; p = .55). CONCLUSIONS: Among patients undergoing heart valve surgery with CPB, 6% HES added to RL for priming compared with only RL increased the risk of the need for blood product transfusion over the hospitalization period.

Partial heart transplantation for destructive infective endocarditis.

Infective endocarditis frequently spreads beyond the valve tissue, especially in the aortic location. Invasive endocarditis may lead to abscess formation or fistula, with substantial tissue loss. Here, the case of a 31-year-old male patient with destructive aortic and pulmonary valve endocarditis and a subaortic mural defect who underwent patch closure of the ventricular septal defect and aortic and pulmonary root replacement and right coronary artery bypass graft is presented. This is an uncommon condition and stress is placed on imaging of the technical aspects of the case.

Indications and outcomes of second aortic procedures after acute type A dissection repair.

OBJECTIVES: Aortic arch or aortic root replacement is not performed in all cases of acute type A aortic dissection (ATAD), and a second aortic procedure will become necessary over time for some patients. Indications and outcomes, of second aortic procedures have not been studied extensively. METHODS: Characteristics and in-hospital outcomes of all patients undergoing surgical repair for type A acute aortic dissection were analysed and patients needing second aortic procedure during follow-up were identified. The latter group was divided in 2 subgroups: on-pump includes patients operated on using cardiopulmonary bypass and off-pump without cardiopulmonary bypass. RESULTS: A total of 638 patients underwent surgery for ATAD; 8% required a second aortic procedure. The most frequent indication for the second aortic procedure was dehiscence of suture lines (44%), followed by arch dilatation (24%). In-hospital mortality was 12%. Isolated ascending aorta replacement at the first surgery was associated with higher incidence of second aortic procedure (P = 0.006). Most patients in the on-pump group underwent a proximal reoperation (75%), with a mortality rate of 14.2%. In-hospital mortality of patients in the off-pump group was 7.7%. Long-term survival analysis showed no difference between groups (P = 0,526), Off-pump patients have greater likelihood of a second intervention during follow-up (P = 0.004). CONCLUSIONS: Extended aortic root surgery and customized aortic arch repair in ATAD could be reasonable to reduce the incidence and mortality of high-risk second aortic procedures.

Perspectives in Training and Professional Practice of Cardiac Surgery in Latin America

ABSTRACT Introduction: There is a lack of information about cardiac surgery training and professional practice in Latin American (LATAM) countries. This study is the first comparative analysis of cardiac surgical training and professional practice across LATAM and provides the fundamentals for future academic projects of the Latin American Association of Cardiac and Endovascular Surgery (LACES). Methods: International survey-based comparative analysis of the training and professional practice of cardiac surgeons across LATAM. Trainees (residents/fellows) and staf (graduated) surgeons from LATAM countries were included. Results: A total of 289 respondents (staf surgeons N=221 [76.5%]; residents/fellows N=68 [23.5%]) from 18 different countries participated in the survey. Most surgeons (N=92 [45.3%]) reported being unsatisfied with their salaries. Most respondents (N=181 [62.6%]) stated that it was difficult to obtain a leadership position, and 149 (73.8%) stated that it was difficult to find a job after completing training. Only half of the trainee respondents (N=32 [47.1%]) reported that their program had all resident spots occupied. Only 22.1% (N=15) of residents/fellows were satisfied with their training programs. The majority (N=205 [70.9%]) of respondents would choose cardiac surgery as their specialty again. Most surgeons (N=129 [63.9%]) and residents/fellows (N=52 [76.5%]) indicated that the establishment of a LATAM cardiac surgery board examination would be beneficial. Conclusion: Modernization and standardization of training, as well as greater access to opportunities, may be required in LATAM to increase professional satisfaction of cardiac surgeons and to reduce disparities in the specialty. Such changes may enhance the regional response to the dynamic challenges in the feld.

Tratamiento quirúrgico de la endocarditis infecciosa activa / Active infective endocarditis: surgical treatment

Resumen: La endocarditis infecciosa, la infección cardiovascular en general, es una enfermedad médico-quirúrgica compleja que requiere un tratamiento multidisciplinario precoz, específico y agresivo. A pesar de los avances médicos, ésta sigue siendo una enfermedad con una morbi-mortalidad elevada, por lo que el tratamiento antibiótico se complementa en un 40-50% de los pacientes mediante intervención quirúrgica. Por lo tanto, es necesario conocer las opciones que pueden llegar a ser utilizadas para extirpar el tejido infectado. El objetivo de este trabajo es discutir aspectos de interés en la cirugía de la endocarditis infecciosa.

Abstract: Infective endocarditis (IE) is a complex disease that requires a multidisciplinary approach and early and aggressive treatment. Despite médical and surgical advances, this disease still has high morbidity and mortality. The antibiotic treatment is complemented in 40-50% of the cases with surgical intervention. Thus, it is useful to be aware of the possibilities that might be contemplated in order to excise the infected tissues. The aim of this work is to discuss current surgical aspects of interest in the surgery IE.

Asociación entre la endocarditis infecciosa por Enterococcus faecalis y la neoplasia de colon: resultados preliminares a partir de una cohorte de 154 pacientes / Relationship between Enterococcus faecalis infective endocarditis and colorectal neoplasm: preliminary results from a cohort of 154 patients

Introducción y objetivos: Así como la asociación entre la endocarditis infecciosa por Streptococcus bovis y la neoplasia colorrectal (NCR) es bien conocida, no se han publicado hasta la fecha resultados de estudios que valoren dicha asociación con la endocarditis infecciosa por Enterococcus faecalis (EIEF). El objetivo de este estudio es determinar si la prevalencia de NCR es mayor en los pacientes con EIEF de foco desconocido que en la población general y en los pacientes con EIEF y foco conocido. Métodos: Análisis retrospectivo de una cohorte de 154 pacientes con EIEF definitiva (109 con foco desconocido y 45 con foco definido) de 2 hospitales universitarios españoles. Estudio de la prevalencia de NCR y otras enfermedades colorrectales. Resultados: Se realizó colonoscopia a 61 pacientes (56%) con foco desconocido, y se diagnosticó NCR a 31 (50,8%): adenoma colorrectal no avanzado en 22 casos (36%), adenoma avanzado en 5 (8,2%) y carcinoma colorrectal (CCR) en 4 (6,6%). Entre los supervivientes al episodio de endocarditis con seguimiento ≥ 2 años, se diagnosticó otro caso de CCR. Por otro lado, solo 6 colonoscopias (13,3%) se llevaron a cabo entre pacientes con foco claro de la EIEF, y se halló NCR en 1 (16,7%). La prevalencia de adenomas era ligeramente mayor que en la población general española de la misma franja de edad, mientras que la prevalencia del CCR resultó 17 veces mayor. Conclusiones: Se diagnosticó NCR a más de la mitad de los pacientes con EIEF y foco desconocido a los que se realizó una colonoscopia. Estos resultados indican que se debe recomendar la realización de una colonoscopia a todo paciente con EIEF y foco no claro (AU)

Introduction and objectives: The association between Streptococcus bovis group infective endocarditis and colorectal neoplasm (CRN) is well-known. However, no studies have assessed the association between Enterococcus faecalis infective endocarditis (EFIE) and CRN. We aimed to determine whether the prevalence of CRN is higher in patients with EFIE and an unclear source of infection than in patients with EFIE and a known source of infection or in the general population. Methods: Retrospective analysis of a cohort of 154 patients with definite EFIE (109 with an unclear source of infection and 45 with an identified source) from 2 Spanish teaching hospitals to determine the prevalence of CRN and other colorectal diseases. Results: In the group with an unknown source of infection, 61 patients (56%) underwent colonoscopy; of these, 31 (50.8%) had CRN. Nonadvanced colorectal adenoma was detected in 22 patients (36%), advanced adenoma in 5 (8.2%), and colorectal carcinoma (CRC) in 4 (6.6%). Among patients who survived the EFIE episode with ≥ 2 years of follow-up, 1 case of CRC was subsequently diagnosed. Only 6 patients (13.3%) with an identified focus of infection underwent colonoscopy; 1 of these patients (16.7%) was diagnosed with CRN. The prevalence of adenomas was slightly higher than that of the Spanish population in the same age range, whereas that of CRC was 17-fold higher. Conclusions: CRN was found in more than half of patients with EFIE and an unclear focus of infection who underwent colonoscopy. Colonoscopy should be recommended in patients with EFIE and an unclear source of infection (AU)

2016 Expert consensus document on prevention, diagnosis and treatment of short-term peripheral venous catheter-related infections in adult / Documento de Consenso sobre la prevención, diagnóstico y tratamiento de las infecciones por catéter venoso periférico en adultos

The use of endovascular catheters is a routine practice in secondary and tertiary care level hospitals. Short peripheral catheters have been found to be associated with the risk of nosocomial bacteremia resulting in morbidity and mortality. Staphyloccus aureus is mostly associated with peripheral catheter insertion. This Consensus Document has been elaborated by a panel of experts of the Spanish Society of Cardiovascular Infections in cooperation with experts from the Spanish Society of Internal Medicine, Spanish Society of Chemotherapy and Spanish Society of Thoracic-Cardiovascular Surgery and aims at define and establish the norm for management of short duration peripheral vascular catheters. The document addresses the indications for insertion, catheter maintenance and registry, diagnosis and treatment of infection, indications for removal and stresses on continuous education as a driver for quality. Implementation of this norm will allow uniformity in usage thus minimizing the risk of infection and its complications (AU)

El uso de catéteres vasculares es una práctica muy utilizada en los hospitales. El uso de catéteres venosos periféricos de corta duración se ha asociado con un elevado riesgo de bacteriemia nosocomial, lo que comporta una no despreciable morbilidad y mortalidad. La etiología de estas infecciones suele ser frecuentemente por Staphylococcus aureus, lo que explica su gravedad. En este documento de consenso, elaborado por un panel de expertos de La Sociedad Española de Infecciones Cardiovasculares con la colaboración de expertos de la Sociedad Española de Medicina Interna, La Sociedad Española de Quimioterapia y la Sociedad Española de Cirugía Torácica y Cardiovascular, pretende establecer unes normes para un mejor uso de los catéteres venosos periféricos de corta duración. El Documento revisa las indicaciones para su inserción, mantenimiento, registro, diagnóstico y tratamiento de las infecciones derivadas y las indicaciones para su retirada; haciendo énfasis en la formación continuada del personal sanitario para lograr una mayor calidad asistencial. Seguir las recomendaciones del consenso permitirá utilizar de una manera más homogénea los catéteres venosos periféricos minimizando el riesgo de infección y sus complicaciones (AU)
