Professor Woong-Han Kim's research lab specializes in pediatric and congenital cardiac surgery, with a focus on surgical outcomes, hemodynamic performance, and long-term management of complex congenital heart diseases. The lab investigates surgical techniques such as the arterial switch operation and Fontan circulation, emphasizing functional improvement, arrhythmia management, and device integration like permanent pacemakers. Key research directions include optimizing surgical strategies to reduce complications such as neoaortic valve regurgitation and improving quality of life through combined procedures. The lab integrates clinical outcomes with advanced surgical interventions to enhance patient survival and functional status.
Figures are computed from collected data and may differ slightly.
Neoaortic valve regurgitation progressed after the arterial switch operation. The degree of regurgitation was more severe in patients with a size discrepancy between the aorta and the pulmonary artery preoperatively.
Fontan conversion with concomitant arrhythmia surgery and permanent pacemaker placement is safe, improves New York Heart Association functional class, and has a low incidence of recurrent arrhythmias. In most patients, concomitant permanent pacemakers are needed.
The 16-mm polytetrafluoroethylene conduit for ECFP showed acceptable outcomes and good haemodynamic status in small-sized patients. According to our results, small patients do not require large conduits to accommodate their growth potential.
A standardized follow-up protocol including CT angiography or coronary angiography after the ASO is required to address coronary artery stenosis. Good reoperation results were observed using the unroofing and cut-back angioplasty techniques.
Mixing of autologous blood with priming volume has relatively significant effects on blood composition, especially in low-bodyweight neonates. In an effort to reduce these effects, mini-volume priming (MP) has been applied in cardiopulmonary bypass (CPB). The present study was designed to examine the effect of MP on clinical outcomes of low-bodyweight neonates undergoing open heart surgery.We retrospectively reviewed medical records of low-bodyweight (2.5 kg or less) neonates who underwent open
MV repair in paediatric patients with congenital mitral stenosis showed acceptable results. The follow-up echocardiogram also revealed satisfactory results. Close follow-up is necessary to detect the development of postoperative mitral stenosis or regurgitation.
Abstract: Interest in academic global surgery, which comprises clinical, educational, and research collaborations to improve surgical care between academic surgeons in high-income countries and low- and middle-income countries (LMICs) and their corresponding academic institutions, has grown over the years. However, there is no collective knowledge of academic global surgery. Thus, this review aims to understand the current landscape of academic global surgery and discuss future directions. A rap
