Rare combined variations of the celiac trunk, accessory hepatic and gastric arteries with co-occurrence of double cystic arteries: a case report.

Folia Morphol (Warsz) 2020 May 27. Epub 2020 May 27.

Department of Anatomy, Jagiellonian University Medical College, 12th Kopernika Street, 31-034 Cracow, Poland.

Many variations of the celiac trunk and hepatic or gallbladder arterial supply have been reported before in many cadaveric and radiologic studies. In this case we present combined anomalies observed in dissected cadaver of a 73-years old female. The left gastric artery arises directly from the abdominal aorta and gives two branches: the right inferior phrenic artery in the proximal part and the accessory left hepatic artery in the distal part.

Multispecies RNA tomography reveals regulators of hematopoietic stem cell birth in the embryonic aorta.

Blood 2020 May 26. Epub 2020 May 26.

University Medical Center Utrecht, Netherlands.

The defined location of a stem cell within a niche regulates its fate, behavior and molecular identity via a complex extrinsic regulation far from being fully elucidated yet. To explore the molecular characteristics and key components of the aortic microenvironment, where the first hematopoietic stem cells (HSCs) are generated during development, we performed genome-wide RNA tomography sequencing on zebrafish, chicken, mouse and human embryos. The resulting anterior-posterior and dorsal-ventral transcriptional maps provided a powerful resource for exploring genes and regulatory pathways active in the aortic microenvironment. Read More

Innovative Left Ventricular Assist Device in High-fidelity Patient Simulator.

Cureus 2020 Apr 21;12(4):e7763. Epub 2020 Apr 21.

Emergency Medicine, San Antonio Military Medical Center, San Antonio, USA.

Left ventricular assist devices (LVADs) are implantable mechanical devices that pump blood from the apex of the left ventricle to the aorta in order to assist the forward flow of blood; they are most commonly used as a bridge to transplant for patients with heart failure. As of February 2019, a total of 25,145 patients with ventricular assist devices have been reported in the Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs). As this number continues to grow, more and more of these patients will inevitably be seen in the acute care setting outside of their defined LVAD center. Read More

Fluid Structure Interaction on Paravalvular Leakage of Transcatheter Aortic Valve Implantation Related to Aortic Stenosis: A Patient-Specific Case.

Comput Math Methods Med 2020 4;2020:9163085. Epub 2020 May 4.

Department of Aerospace Engineering, Universiti Putra Malaysia, Serdang 43400, Malaysia.

This study investigated the impact of paravalvular leakage (PVL) in relation to the different valve openings of the transcatheter aortic valve implantation (TAVI) valve using the fluid structure interaction (FSI) approach. Limited studies were found on the subject of FSI with regards to TAVI-PVL condition, which involves both fluid and structural responses in coupling interaction. Hence, further FSI simulation with the two-way coupling method is implemented to investigate the effects of hemodynamics blood flow along the patient-specific aorta model subjected to the interrelationship between PVL and the different valve openings using the established FSI software ANSYS 16.

Paradoxical aortic stiffening and subsequent cardiac dysfunction in Hutchinson-Gilford progeria syndrome.

J R Soc Interface 2020 May 27;17(166):20200066. Epub 2020 May 27.

Department of Biomedical Engineering, Yale University, New Haven, CT, USA.

Hutchinson-Gilford progeria syndrome (HGPS) is an ultra-rare disorder with devastating sequelae resulting in early death, presently thought to stem primarily from cardiovascular events. We analyse novel longitudinal cardiovascular data from a mouse model of HGPS () using allometric scaling, biomechanical phenotyping, and advanced computational modelling and show that late-stage diastolic dysfunction, with preserved systolic function, emerges with an increase in the pulse wave velocity and an associated loss of aortic function, independent of sex. Specifically, there is a dramatic late-stage loss of smooth muscle function and cells and an excessive accumulation of proteoglycans along the aorta, which result in a loss of biomechanical function (contractility and elastic energy storage) and a marked structural stiffening despite a distinctly low intrinsic material stiffness that is consistent with the lack of functional lamin A.

Delta Systolic Blood Pressure (SBP) Can be a Stronger Predictor of Mortality Than Pre-Aortic Occlusion SBP in Non-Compressible Torso Hemorrhage; an Abotrauma and AORTA Analysis.

Shock 2020 May 21. Epub 2020 May 21.

Our Lady of the Lake Regional Medical Center - Baton Rouge, Louisiana.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is becoming a standardized adjunct for the management in patients with severe non-compressible torso hemorrhage (NCTH). Although guidelines have been developed to help with the best indications for REBOA utilization, no studies have addressed the significance of change in systolic blood pressure (ΔSBP) after REBOA insufflation. We hypothesized that ΔSBP would predict mortality in patients with NCTH and have utility as a surrogate marker for hemorrhage status. Read More

Ascending aorta mechanics in bicuspid aortopathy: controversy or fact?

Asian Cardiovasc Thorac Ann 2020 May 25:218492320928731. Epub 2020 May 25.

Biomechanics Laboratory, Center of Clinical, Experimental Surgery, and Translational Research, Biomedical Research Foundation of the Academy of Athens, Athens, Greece.

Bicuspid aortic valve is the most common congenital cardiovascular defect, often associated with proximal aortic dilatation, and the ideal management strategy is debated. The inconsistency in previous and present guideline recommendations emphasizes the insufficiency of the maximal diameter as the sole criterion for prophylactic repair. Our ability to guide clinical decisions may improve through an understanding of the mechanical properties of ascending thoracic aortic aneurysms in bicuspid compared to tricuspid aortic valve patients and non-aneurysmal aortas, because dissection and rupture are aortic wall mechanical failures.

Hemodynamic Instability in Heart Failure Intensifies Age-Dependent Cognitive Decline.

J Alzheimers Dis 2020 May 20. Epub 2020 May 20.

Department of Psychology, University of Texas at Austin, Austin, TX, USA.

This review attempts to examine two key elements in the evolution of cognitive impairment in the elderly who develop heart failure. First, major left side heart parts can structurally and functionally deteriorate from aging wear and tear to provoke hemodynamic instability where heart failure worsens or is initiated; second, heart failure is a major inducer of cognitive impairment and Alzheimer's disease in the elderly. In heart failure, when the left ventricular myocardium of an elderly person does not properly contract, it cannot pump out adequate blood to the brain, raising the risk of cognitive impairment due to the intensification of chronic brain hypoperfusion.

When to consider a posterolateral descending aortopexy in addition to a posterior tracheopexy for the surgical treatment of symptomatic tracheobronchomalacia.

J Pediatr Surg 2020 May 3. Epub 2020 May 3.

Department of Surgery, Boston Children's Hospital, Boston, MA. Electronic address:

Purposes: The descending thoracic aorta typically crosses posterior to the left mainstem bronchus (LMSB). We sought to evaluate patient factors that may lead one to consider a posterolateral descending thoracic aortopexy (PLDA) in addition to a posterior tracheopexy (PT) in the surgical treatment of symptomatic tracheobronchomalacia (TBM) that involves the LMSB.

Methods: Retrospective review of patients who underwent PT with or without PLDA between 2012 and 2017. Read More

Neonatal pulmonary sequestration (PS) with rhabdomyomas-like hyperplasia: A case report.

Medicine (Baltimore) 2020 May;99(20):e20052

Children's Hospital of Capital Medical University, Beijing, China.

Introduction: Pulmonary sequestration (PS) is a rare pulmonary congenital malformation characterized by disconnection with the tracheobronchial tree or the pulmonary arterial blood supply thus impeding the connection to the arterial blood supply from systemic circulation, ultimately resulting in a non-functional lung.

Patient Concerns: A 73-day-old boy with rhabdomyomatoid hyperplasia was hospitalized for cough and fever 2 months after birth.

Diagnoses: Routine B-ultrasound revealed a cystic malformation in the right lung. Read More

Cannulation of the carotid artery for minimally invasive mitral or tricuspid valve surgery.

Ann Thorac Surg 2020 May 19. Epub 2020 May 19.

From the Department of Cardiac Surgery, Medical University of Innsbruck.

Remote access perfusion for minimally invasive mitral surgery is commonly achieved by femoro-femoral bypass. We describe the use of the carotid artery as an inflow in two patients with severe calcifications of the abdominal aorta and the iliac arteries who underwent minimally invasive mitral and tricuspid valve repair. The easy and fast access to the vessel and the lack of interference with the transthoracic clamp and the scope are the major advantages of the carotid compared other alternatives such as the axillary artery.
