Objective Myocardial protection is the most important in cardiac surgery. We compared our modified single-dose long-acting lignocaine-based blood cardioplegia with short-acting St Thomas 1 blood cardioplegia in patients undergoing single valve replacement.MethodsA total of 110 patients who underwent single (aortic or mitral) valve replacement surgery were enrolled. Patients were divided in two groups based on the cardioplegia solution used. In group 1 (56 patients), long-acting lignocaine based-blood cardioplegia solution was administered as a single dose while in group 2 (54 patients), standard St Thomas IB (short-acting blood-based cardioplegia solution) was administered and repeated every 20 minutes. All the patients were compared for preoperative baseline parameters, intraoperative and all the postoperative parameters.ResultsWe did not find any statistically significant difference in preoperative baseline parameters. Cardiopulmonary bypass time were 73.8±16.5 and 76.4±16.9 minutes (P=0.43) and cross clamp time were 58.9±10.3 and 66.3±11.2 minutes (P=0.23) in group 1 and group 2, respectively. Mean of maximum inotrope score was 6.3±2.52 and 6.1±2.13 (P=0.65) in group 1 and group 2, respectively. We also did not find any statistically significant difference in creatine-phosphokinase-MB (CPK-MB), Troponin-I levels, lactate level and cardiac functions postoperatively.Conclusion This study proves the safety and efficacy of long-acting lignocaine-based single-dose blood cardioplegia compared to the standard short-acting multi-dose blood cardioplegia in patients requiring the single valve replacement. Further studies need to be undertaken to establish this non-inferiority in situations of complex cardiac procedures especially in compromised patients.

The development of left atrial myxoma after coronary artery bypass graft surgery is a rare entity. A 60-year-old man with previous off-pump coronary artery bypass grafting four years ago with patent coronary grafts was diagnosed with left atrial mass. The patient underwent successful resection of the same through minimally invasive right anterolateral thoracotomy. Histopathology of the atrial mass confirmed the diagnosis of atrial myxoma.

Bilateral superior vena cava (SVC) with bilateral partial anomalous pulmonary venous connection is a very rare congenital cardiac malformation. Here, we are reporting a case of 18-year-old male who had bilateral SVC with bilateral anomalous pulmonary venous connection associated with ostium secundum atrial septal defect. The patient underwent successful surgical correction for the same.

BACKGROUNDCoronary Artery Bypass Grafting (CABG) is one of the most frequently done cardiac surgical procedures. However, with the advancements in catheter-based interventional procedures, the category of patients taken up for CABG is gradually being restricted to more high-risk group. Additional surgical procedures like Coronary Endarterectomy (CE) are needed for treating such high-risk coronary artery disease to achieve complete revascularisation. Off-pump coronary endarterectomy can be performed safely with morbidity and mortality comparable with those of conventional coronary endarterectomy.
