Article Abstract
A 57-year-old man with coronary bypass surgery experienced spontaneous rupture of a vein graft 16 months following his operation. Multislice computed tomography revealed a perforation of the saphenous vein graft to the obtuse marginal branch. 3D imaging was useful for diagnosis and in planning treatment. Hesitation to perform surgical treatment occurred due to inflammation in the patient, therefore we successfully implanted a polytetrafluoroethylene-covered stent to occlude the site of perforation. The use of a covered stent for a patient showing clear leakage of dye during angiography should be considered as an alternative to surgical intervention for a ruptured vein.
This study aimed to construct machine learning models and predict prolonged intensive care units (ICU) stay in patients receiving perioperative intra-aortic balloon pump (IABP) therapy during cardiac surgery. 236 patients were divided into the normal (≤ 14 days) and prolonged (> 14 days) ICU groups based on the 75th percentile of ICU duration across the entire cohort. Seven machine learning models were trained and validated.
Endothelial cells control the vascular tone of arterial grafts used for coronary artery bypass surgery and react to changes in local shear stress. The vascular adaptations induced by endothelial cell activation affect the outcome of surgical grafts and can be predicted based on the set-point theory. In this Hypothesis piece, it is proposed that the set-point concept should inform surgical decision making for coronary artery bypass surgery.
Coronary artery disease (CAD) remains a leading cause of morbidity and mortality worldwide, particularly among complex high-risk and indicated patients (CHIP). Revascularization is often beneficial for these patients; however, it requires thorough risk stratification and close multidisciplinary collaboration between cardiologists and cardiac surgeons to optimize outcomes. Personalized treatment plans, including percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG), are crucial in this context.
Introduction: Myocardial protection with cardioplegia is a crucial approach to mitigate myocardial damage during coronary bypass grafting surgery (CABG) with cardiopulmonary bypass (CPB). The major component of the del Nido cardioplegia solution, Plasma-Lyte A, is difficult to obtain in Iran due to high cost. The objective of the current study was to study if the lactated Ringer's solution as the base for del Nido solution (LR DN) usage is a viable option as a substitute for Plasma-Lyte A in adult patients presenting for CABG surgery.
