Myocardial biopsies are an increasingly important tool to unravel the molecular mechanisms of cardiac disease. We evaluate a novel minimally invasive trans-thoracic approach for left-ventricular (LV) intra-mural biopsies, which enables repetitive ind

A comparative study was conducted to evaluate the feasibility of a fiber-optic sensor in invasive blood pressure measurements. Static and wide-bandwidth stimuli were offered to the fiber-optic, Millar, Baxter, and Sentron devices to measure static tr

Venous cannulae undergo continuous improvements to achieve better and safer venous drainage. Several cannula tests have been reported, though cannula performance during inlet obstruction has never been a test criterion. In this study, five different

The objective of this study was to investigate venous collapse (VC) related to venous drainage during the use of an extracorporeal life support circuit. A mock circulation was built containing a centrifugal pump and a collapsible vena cava model to s

Objectives: Electrical remodeling in cardiac hypertrophy often involves the downregulation of K+ currents, including beta-adrenergic (beta-A)-sensitive I-Ks. Temporal patterns of ion-channel downregulation are poorly resolved. In dogs with complete a
