A compact integrated microfluidic oxygenator with high gas exchange efficiency and compatibility for long-lasting endothelialization.

Lab Chip 2021 Jul 26. Epub 2021 Jul 26.

Université Paris-Saclay, CNRS, Centre de Nanosciences et Nanotechnologies C2N, UMR9001, Palaiseau 91120, France.

We have developed and tested a novel microfluidic device for blood oxygenation, which exhibits a large surface area of gas exchange and can support long-term sustainable endothelialization of blood microcapillaries, enhancing its hemocompatibility for clinical applications. The architecture of the parallel stacking of the trilayers is based on a central injection for blood and a lateral injection/output for gas which allows significant reduction in shear stress, promoting sustainable endothelialization since cells can be maintained viable for up to 2 weeks after initial seeding in the blood microchannel network. The circular design of curved blood capillaries allows covering a maximal surface area at 4 inch wafer scale, producing high oxygen uptake and carbon dioxide release in each single unit. Read More

Int J Cardiol 2021 Jul 12. Epub 2021 Jul 12.

Division of Cardiology, UPMC Children's Hospital of Pittsburgh and Department of Pediatrics, 4401 Penn Ave, Pittsburgh, PA 15224, USA; Pediatric Institute for Heart Regeneration and Therapeutics (I-HRT), UPMC Children's Hospital of Pittsburgh and Department of Pediatrics, 4401 Penn Ave, Pittsburgh, PA 15224, USA; McGowan Institute of Regenerative Medicine, University of Pittsburgh School of Medicine, Pittsburgh, PA 15219, USA. Electronic address:

Background: Patients with Tetralogy of Fallot with pulmonary stenosis (ToF/PS), the most common form of cyanotic congenital heart disease (CHD), develop adverse right ventricular (RV) remodeling, leading to late heart failure and arrhythmia. We recently demonstrated that overactive β-adrenergic receptor signaling inhibits cardiomyocyte division in ToF/PS infants, providing a conceptual basis for the hypothesis that treatment with the β-adrenergic receptor blocker, propranolol, early in life would increase cardiomyocyte division. No data are available in ToF/PS infants on the efficacy of propranolol as a possible novel therapeutic option to increase cardiomyocyte division and potentially reduce adverse RV remodeling.

Tricuspid Regurgitation in Left Ventricular Systolic Dysfunction: Marker or Target?

Front Cardiovasc Med 2021 28;8:702589. Epub 2021 Jun 28.

Echocardiography Laboratory, Istituto di Ricerca a Cura e Carattere Scientifico (IRCCS) San Raffaele Scientific Institute, Milan, Italy.

Far from being historically considered a primary healthcare problem, tricuspid regurgitation (TR) has recently gained much attention from the scientific community. In fact, in the last years, robust evidence has emerged regarding the epidemiological impact of TR, whose prevalence seems to be similar to that of other valvulopathies, such as aortic stenosis, with an estimated up to 4% of people >75 years affected by at least moderate TR in the United States, and up to 23% among patients suffering from heart failure with reduced ejection fraction. This recurrent coexistence of left ventricular systolic dysfunction (LVSD) and TR is not surprising, considered the multiple etiologies of tricuspid valve disease. Read More
