Professor Dong Seop Jeong's research lab specializes in advanced cardiovascular interventions, with a primary focus on structural and valvular heart disease, particularly tricuspid valve repair using the MC(3) ring prosthesis. The lab investigates innovative percutaneous and surgical revascularization strategies, including off-pump coronary artery bypass (OPCAB) and endovascular techniques, for patients with left main coronary artery disease. A significant emphasis is placed on optimizing outcomes in high-risk populations, such as those requiring extracorporeal life support (ECLS) or experiencing cardiac arrest due to massive pulmonary embolism, through comprehensive hemodynamic support and predictive scoring systems. The lab also explores the role of combined procedures—such as mitral annuloplasty with OPCAB—in improving functional and survival outcomes in patients with ischemic mitral regurgitation and reduced ejection fraction.

The MC(3) ring provides good mid-term clinical and echocardiographic results for TR. However, long-term follow-up is mandatory to confirm the stability of this procedure.
Compared with PCI, OPCAB is associated with a lower incidence of MACCE in patients with LMCA disease, determined mainly by the lower incidences of acute myocardial infarction and target-vessel revascularization. The incidence of stroke in the OPCAB group was similar to the PCI group.
Concomitant MAP was more effective against recurrent MR than was OPCAB alone, in patients with LVEF ≤40%. We suggest that MAP should be considered in moderate ischemic MR with low LVEF.

In patients undergoing TTA for AF, mild LAA fibrosis was associated with a lower risk of 5-year AF recurrence. LA strain was the only predictor of mild LAA fibrosis that reflects a lower risk of 5-year AF recurrence.
Off-pump CABG with mainly arterial graft revascularization may be considered a good surgical option for coronary lesions caused by KD.
The study results suggested that TAP can be considered in patients who require DVR, even if the TR grade is less than moderate, in order to prevent the late occurrence of TR.
