Small Device with Big Impact
Retired engineer leads new life with implanted CRT-D
Mr Habibul Islam Khan hardly ventures out of his
house since he suffered from a heart attack 10 year ago. Despite a bypass operation, his heart function has continued to decline over the years. The 56-year old gets tired easily and suffered two scary episodes of breathlessness as a result of his poor heart function. He also has severe irregular heart rhythm, which puts him at risk of sudden cardiac death.
His doctors at Dhaka, Bangladesh recommended him to undergo cardiac resynchronisation therapy, where an implanted device will reduce his heart failure symptoms and improve his survival. They also advised him to seek treatment at the National Heart Centre Singapore (NHCS),where they received sub-specialty cardiology training.
Mr Habibul readily agreed to seek treatment in Singapore. He has confidence of the high standard of care available here, having worked here as an engineer before. Accompanied by his brother,
Dr Azharul Islam Khan, he saw Dr Ching Chi Keong, Co-Director of Electrophysiology and Pacing and Consultant, Department of Cardiology on 27 July 2010.
After careful review of his medical history, Dr Ching concurred with the diagnosis and recommendation of his colleagues in Dhaka. Mr Habibul was admitted and had the cardiac resynchronisation therapy defibrillator (CRT-D) implant done the following day. He was discharged three days later and went back to Dhaka soon after.
Reflecting on their experience at NHCS, Dr Azharul says, “My brother and I are very touched by the care and concern shown to us. From the doctors and nurses to Ms Su Su Htwe who assisted us with all the logistics details, everyone is great! We are especially grateful to Dr Ching, who answered our many questions patiently and is very reassuring despite his busy schedule.”

What is Cardiac Resynchronisation Therapy?
Cardiac resynchronisation therapy makes use of an implantable device called a Cardiac Resynchronisation Therapy Defibrillator (CRT-D). The implantation process involves inserting leads to the heart and connect these leads to a device which will be placed
under the skin below the collarbone. The whole process takes up to 2 hours when done by an experienced cardiologist.
The CRT-D helps to coordinate the beating of the right and left heart by pacing both ventricles at the same time. When the two ventricles are coordinated, the amount of work it takes for the heart to pump blood is reduced. If the patient developed a life-threatening heart rhythm, the device detects it and delivers an electrical shock to restore normal heart rhythm.
This therapy can improve quality of life by decreasing heart failure symptoms up to 60% of patients with congestive heart failure. Similary it will abort a sudden cardiac death episode. After the implantation procedure, patients will need regular checks to check the device.
