Renal Outcome in Patients Undergoing Cardiac Surgery Using Cardiopulmonary Bypass.

Introduction Renal dysfunction is a significant variable in determining the outcome of surgery, such as cardiopulmonary bypass graft and valvular replacement, used to treat cardiovascular diseases. In Saudi Arabia, the incidence of renal failure and diabetes is higher than in most western populations. Our aim is to determine the renal outcome of patients who underwent cardiac surgery at King Faisal Cardiac Center from 2014 to 2017. Methods This a retrospective cohort study using a non-probability consecutive sampling technique for selection of the study population to assess the renal outcome in cardiac surgery patients using cardiopulmonary bypass from May 2014 to June 2017 in King Faisal Cardiac Center, Jeddah. Patients older than 18 years of age undergoing cardiac surgery, with available data, were included. Categorical variables were summarized by percentages and frequencies, and continuous variables by means and standard deviations, or medians and interquartile ranges if their distributions were skewed. Logistic regression was done with post-op renal impairment as the dependent variable and pre-op renal dysfunction, age, gender, smoking status, diabetes, hypertension, dyslipidemia, and cardiopulmonary bypass time as independent variables. Results Our sample size included 244 patients who underwent cardiac surgery in this study period; their mean age was 60.5 (SD =7.5) with a mean body mass index (BMI) of 28.62 (SD=5.19). Among our population, 73% (n = 179) were males and 27% (n =66) were females. Two percent (2%) of patients (n = 5) died within 30 days, 4% of patients (n = 10) with temporary dialysis, 8% of patients (n = 19) with postoperative renal dysfunction, and no patients with permanent dialysis. The data showed a significant relationship between levels of creatinine preoperatively and postoperative renal dysfunction (p-value = 0.0001, OR=1.05, 95% CI of 1.031 to 1.064). Conclusion The main predictor of poor renal outcomes for cardiac surgery is preoperative creatinine. While other factors, such as age, gender, body mass index, cardiopulmonary bypass time, diabetes, hypertension, and dyslipidemia, did not show any risk to the postoperative renal outcome.

Surgical repair for persistent truncus arteriosus in neonates and older children.

OBJECTIVES: Persistent truncus arteriosus represents less than 3% of all congenital heart defects. We aim to analyze mid-term outcomes after primary Truncus arteriosus repair at different ages and to identify the risk factors contributing to mortality and the need for intervention after surgical repair. METHODS: This retrospective cohort study included 36 children, underwent repair of Truncus arteriosus in the period from January 2011 to December 2018 in two institutions. We recorded the clinical and echocardiographic data for the patients preoperatively, early postoperative, 6 months postoperative, then every year until their last documented follow-up appointment. RESULTS: Thirty-six patients had truncus arteriosus repair during the study period. Thirty-one patients had open sternum post-repair, and two patients required extracorporeal membrane oxygenation. Bleeding occurred in 15 patients (41.67%), and operative mortality occurred in 5 patients (14.7%). Patients with truncus arteriosus type 2 (p = 0.008) and 3 (p = 0.001) and who were ventilated preoperatively (p < 0.001) had a longer hospital stay. Surgical re-intervention was required in 8 patients (22.86%), and 11 patients (30.56%) had catheter-based reintervention. Freedom from reintervention was 86% at 1 year, 75% at 2 years and 65% at 3 years. Survival at 1 year was 81% and at 3 years was 76%. High postoperative inotropic score predicted mortality (p = 0.013). CONCLUSION: Repair of the truncus arteriosus can be performed safely with low morbidity and mortality, both in neonates, infants, and older children. Re-intervention is common, preferably through a transcatheter approach.

Factors Influencing Saudi Medical Student's Decision Towards Cardiothoracic Surgery as a Future Career, a Cross Sectional Study.

INTRODUCTION: There has been a progressive decline in students' interest to consider cardiothoracic surgery as future career in the distant regions in the world. There are many factors could explain declining interest in cardiothoracic surgery including diminished caseloads due to the expansive growth of interventional cardiology; length of training programs that influences medical student's perception. King Abdulaziz University student's interest to join the speciality explored in our study. We determined some factors that influence their decision making toward their cardiothoracic career. AIM: We aimed to estimate the current interests of medical students at King Abdulaziz University to pursue a career in Cardiothoracic surgery and to determine the factors that positively or negatively affect their decision. MATERIAL AND METHODS: A self-administered online survey designed on Google form was distributed through email to fourth, fifth, and sixth-year medical students. Five domains; demographics, current career intentions, previous exposure to surgery, experiences and perceptions of cardiothoracic surgery were covered in the questionnaire to identify factors affecting student decision to choose cardiothoracic surgery as a future career. RESULTS: Among 486 students at our institution, 179 (36, 83%) medical students completed the questionnaire more than half of them 91 (50.8%) were males. The percentage of students who considered cardiothoracic surgery as a future career was (4.5%); when asked if they were serious in pursuing a career in cardiothoracic surgery, (14.5%) of the student were affirmative. Of those participated in the survey, Twenty-four students believed they had adequate introduction to the cardiothoracic surgery during their undergraduate program. CONCLUSION: cardiothoracic surgery is falling away behind other specialties as career of choice for many future physicians. It is believed mainly related to inadequate introduction to the field. Increasing exposure and close mentorship is needed to attract more students to pursue a career in cardiothoracic surgery.
