Total arterial anaortic off-pump coronary artery bypass grafting in a patient with heart failure – Case report

AbstractA 69-year-old male diabetic patient of heart failure underwent successful off-pump coronary artery bypass grafting (CABG) using both internal thoracic arteries and left radial artery. There was improvement of left ventricular ejection fraction within 4 days. This is the first ever case report of off-pump CABG in a heart failure patient

Is magnesium sulfate friend or foe of off-pump coronary artery bypass surgery?

Magnesium sulfate is often used empirically in cardiac surgical settings. Magnesium sulfate may cause platelet dysfunction leading to bleeding complication. This editorial commentary discusses the published study of intra-operative use of magnesium sulfate during off-pump coronary artery bypass grafting published in this issue of Indian Heart Journal

Off-pump coronary artery bypass grafting in India

Off-pump Coronary Artery Bypass Grafting (OPCAB) is the latest innovation in cardiac surgery. However OPCAB is not adopted universally. Even there have been suggestions of abandoning OPCAB in a special report. In India, OPCAB has been successfully adopted across the board. There are various evidences which favor OPCAB and are discussed in this review. The purpose of this review is to put forward the perspective of the OPCAB surgeons of our country and critically look at the suggestion of abandoning OPCAB

A novel technique of anesthesia induction in supine position with impaled knife in the back

Current technique of airway management for impaled knife in the back includes putting the patient in lateral position and intubation. We present here a novel technique of anesthesia induction (intubation and central line insertion) in a patient with impaled knife in the back which is simple and easily reproducible. This technique can be used for single lung ventilation using double lumen tube or bronchial blocker also if desired

Anaortic off-pump bilateral internal mammary grafting in severe left ventricular dysfunction – Case report

A 64 years old male diabetic patient with ejection fraction of 16% and renal dysfunction underwent off-pump CABG using both in situ internal mammary artery grafts. Left internal mammary artery was used to bypass left anterior descending artery and right internal mammary artery was used as composite graft. Patient had uneventful recovery and left ventricular ejection fraction improved to 34% within 8 months after surgery. In presence of left ventricular dysfunction, both internal thoracic artery grafting should be preferred for better patency rate and flow reserve. This is the first ever case report of anaortic off-pump bilateral internal thoracic artery grafting in a patient with left ventricular ejection fraction less than 20%

Total arterial anaortic off-pump coronary artery bypass grafting for diffuse coronary disease – A case report

Surgical treatment of diffuse coronary artery disease remains challenging. We present here a diabetic patient, with diffuse coronary disease, revascularized using total arterial anaortic off-pump coronary artery bypass grafting. He received total nine distal grafts. He continues to be asymptomatic after more than 2 years. CT angiography follow-up shows eight out of nine grafts are patent. Anaortic off-pump coronary artery bypass grafting has the least incidence of stroke and arterial grafts have the best long-term patency rate. This is the first case report of nine arterial bypass graft performed off-pump using both internal mammary and both radial arteries. Anaortic total arterial off-pump coronary artery bypass grafting has achieved excellent intermediate term result in this patient of diffuse coronary artery disease

Off-pump coronary artery bypass grafting using continuous heparin infusion

Objectives: Levels of anticoagulation during off-pump coronary artery bypass grafting (OPCAB) remain controversial. Prolonged activated clotting time (ACT) during OPCAB increases blood loss during surgery and can also cause paradoxical increase in postoperative myocardial infarction. Shorter ACT can increase thrombotic complication. Maintaining a steady ACT level is challenging. We have used continuous heparin infusion after initial bolus during OPCAB to maintain a steady low target ACT. The objective of the present study was to assess the effectiveness and safety of heparin infusion in maintaining a steady target ACT level. Methods: This was a prospective study of consecutive OPCAB patients. ACT was measured after initial bolus dose of heparin. Once ACT of more than 200 seconds was achieved, heparin infusion was started to maintain the required level of anticoagulation. CPK-MB was measured in operation room, 6 and 24 hours postoperatively to rule out ischemic complication. Results: ACT could be maintained in target range with heparin infusion in 80.1% patients (161/201). Of the 40 patients with one or more ACT reading less than 200 seconds, 38 patients were managed by increasing the dose of heparin infusion and only 2 patients required additional bolus dose of heparin. Conclusions: Heparin infusion maintains a steady target ACT level and avoids peaks and troughs associated with bolus doses. Lower level of anticoagulation using continuous heparin infusion does not increase ischemic complications. This is the first ever study of use of heparin infusion during OPCAB. We may conclude that heparin infusion is a safe anticoagulation strategy for OPCAB
