RESUMO
Primary cardiac sarcomas are very aggressive, being a challenge to cardio-oncology specialty. Surgical planning and innovative techniques have enhanced the possibility of resection. We have described a case of recurrent primary left atrium angiosarcoma, successfully resected with a modified partial autotransplantation technique, planned using a 3-dimensional model created from computed tomography. (Level of Difficulty: Intermediate.).
RESUMO
BACKGROUND: Infection after cardiovascular surgery is multifactorial. We sought to determine whether the anthropometric profile influences the occurrence of infection after isolated coronary artery bypass grafting (CABG). METHODS: Between January 2011 and June 2016, 1777 consecutive adult patients were submitted to isolated coronary artery bypass grafting. Mean age was 61.7 ± 9.8 years and 1193 (67.1%) were males. Patients were divided into four groups according to the body mass index (BMI) classification: underweight (BMI < 18.5 kg/m2 ; N = 17, 0.9%), normal range (BMI: 18.5-24.99 kg/m2 ; N = 522, 29.4%), overweight (BMI: 25-29.99 kg/m2 ; N = 796, 44.8%), and obese (BMI > 30 kg/m2 ; N = 430, 24.2%). In-hospital outcomes were compared and independent predictors of infection were obtained through multiple Poisson regression with a robust variation. RESULTS: Independent predictors of any infection morbidity were female sex (relative ratio [RR], 1.47; p = .002), age > 60 years (RR, 1.85; p < .0001), cardiopulmonary bypass > 120 min (RR, 1.89; p = .0007), preoperative myocardial infarction < 30 days (RR, 1.37; p = .01), diabetes mellitus (RR, 1.59; p = .0003), ejection fraction < 48% (RR, 2.12; p < .0001), and blood transfusion (RR, 1.55; p = .0008). Among other variables, obesity, as well as diabetes mellitus, were independent predictors of superficial and deep sternal wound infection. CONCLUSIONS: Other factors rather than the anthropometric profile are more important in determining the occurrence of any infection after CABG. However, surgical site infection has occurred more frequently in obese patients. Appropriate patient selection, control of modifiable factors, and application of surgical bundles would minimize this important complication.

BACKGROUND AND AIM OF THE STUDY: In developed countries, the shortage of viable donors is the main limiting factor of heart transplantation. The aim of this study is to determine whether the same reality applies to Brazil. METHODS: Between January 2012 and December 2014, 299 adult heart donor offers were studied in terms of donor profiles and reasons for refusal. The European donor scoring system was calculated, being high-risk donors defined as more than 17 points. The donor scoring system was used to objectively determine the donor profile and correlate with donor acceptance and posttransplant primary graft dysfunction and recipient survival. Cox proportional hazard model was used in determining the predictors of long-term mortality. RESULTS: The rates of donor acceptance and heart transplants performed were 45.8% and 19.3%, respectively. Reasons for refusal were mostly nonmedical (53.7%). The majority of donors were classified as high-risk (65.5%). Hearts from high-risk donors did not impact primary graft dysfunction (14.3% vs 10%; P = .6), neither long-term survival (P = .4 by logrank test). Recipient's age was greater than 50 years (hazard ratio, 6.02; 95% confidence interval, 2.41-16.08; P < .0001) and was the only predictor of long-term mortality. CONCLUSIONS: The shortage of donors is not the main limiting factor of heart transplantation in the Mid-West of Brazil. Nonmedical issues represent the main reason for organ discard. Most of the donors are classified as high risk which indicates that an expanded donor pool is a routine practice in our region, and donor scoring does not seem to influence to proceed with the transplant.
