This is the latest technique of doing CABG where the heart lung machine is not used. This obviates the drawbacks of the heart lung machine mentioned above and makes the Bypass quicker and safer. The patient gets better earlier as compared to On Pump Bypass and may require very little blood transfusion. It is advisable to do ‘Off Pump Bypass’ in most of the cases. It is also known as ‘Beating Heart Bypass Surgery’ as the heart is beating during the operation.
Which technique to use, ‘On Pump’ or ‘Off Pump’? The final decision is made by the surgeon and depends on what he thinks is the best option for the patient on hand.
