A/Prof Michael George Caleb graduated form National University of Singapore with MBBS in 1987. He underwent advanced cardiac specialty training at the Cleveland Clinic, Ohio, United States of America and The Peter Munk Cardiac Centre at University of Toronto, Canada from 1996 to 1998.
He was a Senior Consultant heart surgeon at The National Heart Centre, Singapore till 2005 and joined the National University Hospital in 2005, where he is currently a Senior Consultant and Director, Mechanical Heart Support.
His abilities and special interests include:
-
All aspects of mechanical heart support for acute and chronic heart failure, including the use of extracorporeal membrane oxygenation, temporary ventricular assist devices and implantable long term mechanical pumps.
-
Beating heart (off-pump) coronary bypass surgery including all arterial graft surgery.
-
Minimally invasive endoscopic vein harvesting for coronary bypass surgery.
-
Mitral valve repair for complex lesions including bileaflet repairs.
-
Radiofrequency ablation ( RFA-MAZE) for chronic and paroxysmal atrial fibrillation. RFA is added to the mitral valve repairs thereby avoiding warfarin in this group of patients.
-
Heart failure surgery for end stage heart failure as an alternative to heart transplants. This includes left ventricular reshaping(DOR) and mitral valve annular reduction.
-
Stentless aortic valve surgery for elderly patients with small aortic roots, thereby avoiding merchanical valves and warfarin anticoagulation.
-
Open thoracic aneurysm surgery including arch aneurysms, in combination with endovascular stenting, where required.
-
Transmyocardial laser revascularization.
-
All aspects of lung surgery, including Video Assisted Thoracoscopic Surgery.
-
All aspects of vascular surgery.
