“…Cardiopulmonary bypass (CPB) is a standard procedure in cardiac surgery 1 , 2 . The distal ascending aorta is primarily chosen for cannulation, positioning the cannula close to the origin of the brachiocephalic trunk 2 , 3 . However, CPB is accompanied by a high incidence of neurological complications 4 , among which stroke is a major factor 5 , 6 : Generally, a 6% prevalence of stroke after cardiac surgery is reported 7 , of which 2–3% are associated specifically with CPB 8 , 9 .…”

Cardiopulmonary bypass (CPB) is a standard technique for cardiac surgery, but comes with the risk of severe neurological complications (e.g. stroke) caused by embolisms and/or reduced cerebral perfusion. We report on an aortic cannula prototype design (optiCAN) with helical outflow and jet-splitting dispersion tip that could reduce the risk of embolic events and restores cerebral perfusion to 97.5% of physiological flow during CPB in vivo, whereas a commercial curved-tip cannula yields 74.6%. In further in vitro comparison, pressure loss and hemolysis parameters of optiCAN remain unaffected. Results are reproducibly confirmed in silico for an exemplary human aortic anatomy via computational fluid dynamics (CFD) simulations. Based on CFD simulations, we firstly show that optiCAN design improves aortic root washout, which reduces the risk of thromboembolism. Secondly, we identify regions of the aortic intima with increased risk of plaque release by correlating areas of enhanced plaque growth and high wall shear stresses (WSS). From this we propose another easy-to-manufacture cannula design (opti2CAN) that decreases areas burdened by high WSS, while preserving physiological cerebral flow and favorable hemodynamics. With this novel cannula design, we propose a cannulation option to reduce neurological complications and the prevalence of stroke in high-risk patients after CPB.

“…[3] Cardiopulmonary bypass serves the purpose of acting in place of the patient's heart and lungs during a cardiac operative procedure. [4] Residents usually begin their operative journey in cardiac surgery by learning to put a patient on cardio-pulmonary bypass machine and basic surgery like ostium secundum atrial septal defect.…”

In the current era of cardiothoracic surgery, a trainiee embarks on his operative journery with learing to operate upon a patient suffering from ostium secundum atrial septal defect. This procedure involves all the essential steps required in cardiac surgery procedures and one should master the steps of this operation to be able to perform and understand other cardiac operations. OS-ASD closure is one of the first open heart procedures performed by a trainee or resident. This article deals with detailed operative steps as to how to perform sternotomy, put a patient on cardiopulmonary bypass machine, perform atrial septum defect closure and get a patient off cardiopulmonary bypass. Procedural training in current practice is often unsystematic and unstructured, and validated teaching methods have not been well integrated into clinical education. Minutest details performed during the procedure are mentioned in this article aimed for residents in cardiovascular thoracic surgery. Though there are multiple texts available in literature as how to perform the above mentioned procedure, they lack in technical details and thus residents have difficulty while operating. I would like to delineate detailed steps for ostium secundum atrial septum closure for beginners. This is meant for revision preoperatively of all the step one has to perform while doing surgery.
