ABSTRACT
Introduction The aim of this research is to evaluate the in-hospital and early outcomes of the first 100 adult cardiac surgeries performed at a newly developed satellite center in Sukkur, Pakistan. Methods This is an audit of the first 100 adult cardiac surgeries performed at a newly developed satellite center of the National Institute of Cardiovascular Diseases (NICVD) at Sukkur, Pakistan, from March 2018 to November 2018 with 12 months of post-operative follow-up. Patients were offered off-pump coronary artery bypass (OPCAB), on-pump coronary artery bypass (ONCAB), mitral valve replacement (MVR), aortic valve replacement (AVR), minimally invasive cardiac surgery (MICS), and congenital adult congenital heart disease (ACHD) procedures by expert faculty of NICVD with a minimum of five years of post-fellowship experience. Results The mean age was 47.11 ± 14.6 years, with a male predominance of 77%. Hypertension and smoking were the most common risk factors that were observed in 32% and 33%, respectively, followed by diabetes and dyslipidemia with a frequency of 20% and 9%, respectively. The mean EuroSCORE (European System for Cardiac Operative Risk Evaluation) II for this patient cohort was 1.165 ± 0.50, with a maximum score of 2.3 in one patient. Out of 100 procedures, 51 were ONCAB, 19 were OPCAB, 16 were MVR, three were AVR, nine were ACHD, and two were MICS. Survival status post-operative as well as after one year was 100%. The frequency of post-operative bleeding was 7%, mean post-operative mechanical ventilation time was 213 ± 273 hours, and in-hospital stay was 5.41 ± 0.165 days. Lost to follow-up at one year was 4% (four). During the follow-up assessment, 39.5% of the patients had complained of mild-to-moderate intensity retrosternal pain and 4.2% had superficial surgical site infection of the sternal wound. A significant improvement in functional class was observed in 38.5% of patients, whereas 4.2% (four) had a significant drop in functional class post-operatively. Conclusion Providing tertiary care and early cardiac surgical facility to the people of Sukkur at their doorstep, in a newly developed satellite center, has resulted in improved outcomes, early quality treatment facility, and avoidance of long travel time.
ABSTRACT
OBJECTIVE: To determine the early effects of Coronary Artery Bypass Grafting (CABG) on regional left ventricular wall motion abnormality in patients undergoing surgery for proven Coronary Artery Disease (CAD). DESIGN: Quasi-experimental study. PLACE AND DURATION OF STUDY: Department of Cardiac Surgery, National Institute of Cardiovascular Diseases, Karachi. from October 2005 to April 2006. PATIENTS AND METHODS: A total of a 100 adult patients who underwent elective CABG were selected. Pre-operative echocardiography was done to note if segmental left ventricular wall motion at basal, mid and apical levels were normal, hypokinetic, akinetic, dyskinetic, or aneurysmal. Postoperative echocardiography was done between 4th and 6th day and change in left ventricular segmental wall motion was noted. RESULTS: Seventy-five patients (n=75) were included in the analysis. These results showed that effect of CABG on anterior segmental wall motion abnormalities was insignificant (p=.609), the effect on the anterior IVS showed deterioration of segmental wall motion and this effect was significant (p=.001), effect is insignificant on anteriolateral segmental wall motion abnormalities (p=.078), normal pre-operative segments in posterior wall showed stability (p=.664) while disappearance of dyskinetic, reduction in akinetic segments postoperatively and inferior wall motion have same effects as of posterior wall. Comparison of pre-operative and postoperative echocardiographic data revealed early improvement in segmental wall motion of posterior and inferior wall, while alterations in segmental wall motion of anterior, anterior-lateral and septal wall. CONCLUSION: Myocardial revascularization by CABG improves early left ventricular regional wall motion abnormalities where SVG is used as conduit for revascularization whereas no significant improvement occurs in early segmental wall motion in areas revascularized by LIMA.
