Pre-operative use of intra-aortic balloon pump has been shown to prevent this complication in high risk patients. The role of balloon pump in high risk patients has been questioned by our group. We modified the role of balloon pump in our patients, thus avoiding the conversion to cardiopulmonary bypass. Methods: 4063 off-pump coronary bypass surgeries were performed by a single surgeon in our center, over thirteen years. 130 intra-aortic balloons used between July 2002 and December 2015 were removed from the the-ater, once the distal anastomosis was performed. We studied this group of patients for—time and need for insertion, duration of balloon used, local insertion problems and survival. Results: Initially, we inserted intra-aortic balloons in high risk patients. We observed that, patients with low ejection fraction and patients with critical left main coronary artery disease were not the ones who actually needed balloon pump support. It was the patients who had ongoing ischemia, with preserved left ventricular function, and ST depression intra-operatively, who needed balloon pump support to perform complete anatomical revascularization. Conclusions: Intra-aortic balloon pump has helped us to position the heart without hemodynamic instability, thereby avoiding conversion to cardio-pulmonary bypass. This enabled us to perform off-pump surgery in virtually all areas of the heart, thus maintaining perfect hemodynamics.展开更多
We hereby report a case of Kawasaki disease in a 32 year old male, with giant aneurysm of both coronary arteries and severe LV (left ventricular) dysfunction who underwent OPCAB (off pump coronary artery bypass grafti...We hereby report a case of Kawasaki disease in a 32 year old male, with giant aneurysm of both coronary arteries and severe LV (left ventricular) dysfunction who underwent OPCAB (off pump coronary artery bypass grafting) two years ago. He presented with acute myocardial infarction of his anterior wall of left ventricle. He was stabilised with medical management and was taken up for surgery when his enzymes became normal. His LV function had improved over the time and now has a good ejection fraction.展开更多

The lack of frank pulsatility and signs of inflammation though was a bit confusing, the Doppler and CT angiogram clinched the diagnosis. We were able to surgically resect and reform the ICA using the native vessel itself, which is an unusual technique, which we thought was worth presenting.展开更多

Every time a disposable stabilizer is used and discarded, we add to the carbon footprint we leave behind. We had been working on developing such a stabilizer, and had finally come up with a simple indigenous (reusable) metallic stabilizer (SIMS). We have used it for over 600 consecutive off pump coronary artery bypass (OPCAB) with excellent results. The anatomy of the stabilizer is described here along with a comparison of this stabilizer with the commercially available one.展开更多
