Time has fascinated the history of humanity since its origins: in particular, preand post-Aristotelian philosophy, Galilean science, Albert Einstein’s theory of relativity, and Enrico Fermi’s quantum physics. The space-time in the theory of relativity is an indissoluble variable - there is no space without time and vice versa. Organ protection from ischemia is a matter of time in relation to the technique; there are many different cardioplegia solutions of varying compositions used for myocardial arrest and protection in cardiac surgery, and the choice of cardioplegia is often up to institution or surgeon preference. In our experience the use of DN solution increases temporarily hemodilution in extracorporeal circulation and is a variable that acts directly on colloid oncotic pressure (COP), determined by all plasma proteins in the intraand extravascular compartments, and plays a key role in transcapillary fluid movement. A decreased COP increases transcapillary fluid movement, which leads to tissue edema and, combined with hemodilution, may compromise peripheral tissues oxygenation and end-organ perfusion. The reduction of hemoglobin content has an impact during CPB on corrective action for red blood cell, hypothermia, and ultrafiltration uses, and it also has an impact on the oxygen delivery (DO₂) - there is ample evidence that an indexed DO₂< 280 ml/min/m2 exposes the patients to postoperative risk and incidence of acute kidney injury (AKI). The use of DN solution for the abovementioned aspects in the MiECC in particular for hemodilution variable appears in contrast, despite the literature being clearly in favor of this methodology in the context of conventional extracorporeal circulation. But there is another aspect we should ask ourselves when choosing myocardial protection solution: 1) Should it be chosen in relation to time according to the surgical technique? 2) Should it be chosen in relation to patient typology and multi-organ preservation during and after CPB? From this point of view, there is no myocardial solution that integrates the answer to these two questions, and consequently the one that meets the benefits and objectives set by MiECC is the BC solution. The literature on minimally invasive cardiac surgery, independently of the myocardial solution used, showed a significant association between cross-clamping time and mortality, low cardiac output syndrome, and AKI, so moving towards a more physiological CPB such as the MiECC is perhaps the most reliable answer.

3D Whole-Heart Imaging in Cardiovascular #MRI: Exploring the Range of Clinical Applications by Eva Nyktari, MD (Cardiovascular MRI Unit, ONASSIS CARDIAC SURGERY CENTER, Athens, Greece); et al. Initially introduced for coronary artery visualization, 3D whole-heart navigator-based acquisitions have been used especially to delineate complex congenital anatomy and morphology. The technique is superior to other imaging modalities used in congenital heart disease (#CHD), as it is free from ionizing radiation and does not require breath-holding. It also allows the acquisition of full-volume data including the entire heart and thoracic vasculature at a specific point of the cardiac cycle (usually end-diastole) with high SNR and isotropic voxel resolution that enables reconstruction in any plane during post processing. Apart from its value in anatomy and morphology, free-breathing high-isotropic-resolution 3D whole-heart LGE imaging has been established as a valid method of tissue characterization in a wide range of ischemic and non-ischemic cardiomyopathies. Recent major developments in #electrophysiology (#EP) #ablation procedures for #arrhythmia treatment have raised the need for novel 3D whole-heart high-resolution LGE techniques to image thin-wall cardiac chambers such as the atria and right ventricle. Technological progress has made it possible to both identify the arhythmogenic substrate and illustrate its underlying architecture. This information has been used to aid or even guide EP procedures, increasing both safety and success rates. The authors focus on using 3D whole-heart imaging in adult congenital heart disease and arrhythmias, and on how it helps the invasive cardiologists on the Structural Heart Disease team and on the EP team in their daily practice.

Innovative Computational Tools for Enhancing Cardiovascular Surgery Outcomes We are proud to present here Eirini Kardampiki, PhD doctoral thesis “Development of Computational Tools for Cardiovascular Applications,” discussed at the University of Rome Tor Vergata. This research develops computational tools to support cardiovascular surgeries, specifically Endovascular Aneurysm Repair (EVAR) and the modified Blalock–Taussig shunt (MBTS). EVAR is a minimally invasive procedure for treating abdominal aortic aneurysms in patients with aortic diameters over 3 cm, but it faces complications like guidewire-induced deformations and post-operative thrombus formation. To address these, a pipeline using Reduced Order Modelling (ROM) and Finite Elements (FE) simulations was created to predict aortic configurations in real-time, aiding intraoperative navigation. Additionally, a Computational Fluid Dynamics (CFD) analysis identified thrombus-prone regions in stent-grafts, finding Zenith Alpha more susceptible due to higher recirculation and shear strain rates. For MBTS, which addresses cyanotic heart diseases by implanting a synthetic shunt between the subclavian and pulmonary arteries, a static ROM trained on CFD data was developed to recommend personalized shunt morphology, improving implant sizing. The research demonstrated the ROM’s significant precision and potential clinical integration. In summary, the studies developed tools for real-time predictions and thrombus formation analysis to enhance surgical outcomes.
