Dr Ko Chung Sen – Cardiothoracic Surgeon, KPJ Ipoh. We are deeply grateful to Dr Ko Chung Sen for his exceptional care and skill in performing my mom’s bypass surgery. From the very beginning, Dr Ko was calm, reassuring, and thorough in his explanations, which gave our family great confidence and peace of mind during a very stressful time. The surgery went smoothly, and mom’s recovery has been progressing well under his care. What we truly appreciate is not just his medical expertise, but also his professionalism, patience, and genuine concern for his patient’s well-being during follow-ups. Thank you, Dr Ko, for mending my mom’s heart and giving our family renewed hope.
