General FAQs of Redo-CABG Surgery
• Redo Coronary Artery Bypass Graft is required only in a small percentage of patients who had previously undergone CABG but experience constant angina, progression of disease, new blocks or sometimes re-blockage of the graft or the coronary arteries.
• This generally occurs few years after the primary CABG.
• Redo CABG is required in symptomatic patients where surgical revascularization is indicated.
• In comparison to PCI, CABG Redo Surgery is preferred in patients with more disease vein grafts and/or low cardiac function.
• Redo CABG is also preferred in patients with severe symptoms or extensive ischemia.
• In patients with freshly occluded saphenous vein graft (SVG), CABG is indicated if the native artery appears unsuitable for PCI or when many of the important grafts are occluded.
Redo-CABG is superior choice of surgery than PCI in following conditions:
• Late (>5years) stenosis.
• Multiple stenotic vein grafts.
• Diffusely atherosclerotic vein grafts.
• Stenotic LAD vein graft.
• No patent ITA graft.
• Abnormal left ventricular function.
Benefits of a Redo-CABG are:
• Better chances of survival.
• Reduced chances of cardiac events and recurrent angina.
• Patient can lead a normal life with minimum medications.
• Comparably effective than other procedures in patients with co-morbid conditions.
• Redo Coronary Artery Bypass Grafting (CABG) is quite a challenging procedure than the primary CABG as it requires re-entry into the sternum as well as opening of the heart. That is why it requires far better skills and expertise of a cardiac surgeon to perform a redo by-pass surgery than a primary CABG.
• It is an extremely demanding surgery in terms of surgeon skills as well as patient care after Redo surgery.
• With growing technology, the Redo CABG procedure has become almost as safe as the primary CABG operation if performed by an experienced surgeon in a hospital with complete infrastructure.
The outcomes of Redo CABG have also been improving in recent times despite of the patients having co-morbid conditions.
