Special Issue Information

Dear Colleagues,

The human cardiac cycle is a set of connected vessels in which one change disturbs blood hemodynamic in the whole system. Therefore, it is essential to predict the character of blood hemodynamic changes before and after surgical intervention. Currently, physicians and engineers are working together to address the aforementioned issues, often with the use of human or animal vessels or vascular tissue as well as their digital presentation in a numerical approach. As this approach may reduce morbidity or mortality, early diagnosis and treatment, including preoperative care and surgical intervention, is mandatory. Therefore, the topic of blood hemodynamic reconstruction in a numerical and experimental approach combines all the above-mentioned aspects and allows the dissemination of valuable results.

This Special Issue of the Journal of Clinical Medicine will be devoted to providing a focused perspective in specific areas of blood hemodynamic reconstruction, with topics including but not limited to:

- Computational fluid dynamic technique for blood hemodynamic reconstruction;

- Bioreactor for artificial vessels and human tissues;

- Optimization of the process of vascular implant placement;

- Fluid structure interaction of moving wall and blood components.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).

The aim of this study was to create a mathematical approach for blood hemodynamic description with the use of brightness analysis. Medical data was collected from three male patients aged from 45 to 65 years with acute type IIIb aortic dissection that started proximal to the left subclavian artery and involved the renal arteries. For the recognition of wall dissection areas Digital Imaging and Communications in Medicine (DICOM) data were applied. The distance from descending aorta to the diaphragm was analyzed. Each time Feret (DF) and Hydraulic (DHy) diameter were calculated. Moreover, an average brightness (BAV) was analyzed. Finally, to describe blood hemodynamic in the area of aortic wall dissection, mathematical function combining difference in brightness value and diameter for each computed tomography (CT) scan was calculated. The results indicated that DF described common duct more accurately compare to DHy. While, DHy described more accurately true and false ducts. Each time when connection of true and false duct appeared, true duct had lower brightness compare to common duct and false duct. Moreover, false duct characterized with higher brightness compare to common duct. In summary, the proposed algorithm mimics changes in brightness value for patients with acute type IIIb aortic dissection. Full article
