Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

Artificial Organs, Volume 50, Issue 10, Page 1360-1371, October 2026.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

Hemodynamics of Fontan Failure

, 2017
Background Nonpulsatile pulmonary blood flow in Fontan circulation results in pulmonary vascular disease, but the potential relationships between pulmonary vascular resistance index (PVRI) and Fontan failure have not been studied.

Acute Effects of Enhanced External Counterpulsation in Adults With Fontan Circulation

JACC: Advances
Background: Patients with Fontan circulation exhibit reduced cardiac output. Objectives: The purpose of this study was to study the safety and acute hemodynamic effects of enhanced external counterpulsation (EECP) in a cohort of Fontan patients. Methods:

5D Flow MRI Reveals Respiration‐Driven Changes in Blood Flow Energetics in Congenital Heart Disease

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1342-1354, September 2026.
ABSTRACT Purpose Hemodynamic monitoring is essential for patients with right‐sided congenital heart disease (CHD). Respiration may have an increased impact on pulmonary flow in these patients that cannot be assessed by standard tools including 4D flow MRI. This study uses 5D flow MRI to assess respiratory‐cycle variations in flow energetics in patients

Closing in on the perfect Fontan [PDF]

The Journal of Thoracic and Cardiovascular Surgery, 2014
Since the introduction of the Fontan operation more than 4 decades ago, many modifications to the operation have occurred and have been debated in the name of finding the ‘‘perfect’’ Fontan. Along the way, the ‘‘Ten Commandments’’ for a Fontan have been reduced to 4 or 5.
