The isolated working guinea pig heart: A functional and electrophysiological characterisation

Experimental Physiology, EarlyView.
Abstract Small animal isolated perfused hearts have been used for over 150 years for the study of cardiac physiology and pharmacology. The guinea pig heart represents the smallest mammalian heart that replicates key features of the human heart – for example, with respect to cardiac action potential duration, ion channel expression, excitation ...

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

14‐3‐3 proteins: Regulators of cardiac excitation–contraction coupling and stress responses

The Journal of Physiology, EarlyView.
Abstract figure legend 14‐3‐3 protein interactions in cardiac regulation. Schematic representation of 14‐3‐3 binding partners in excitation–contraction coupling, transcriptional regulation/development and stress response pathways. Asterisks indicate targets where the exact 14‐3‐3 binding site is unknown.

Incidence, Prevention, and Management of Periprocedural Complications of Left Atrial Appendage Occlusion.

, 2018
Major procedural complications related to left atrial appendage occlusion (LAAO) are relatively infrequent but may be associated with major morbidity and mortality. LAAO operators should be knowledgeable about these potential complications.

Concomitant left atrial appendage exclusion during cardiac surgery: a single-center case series on technique profile, residual flow, and early safety

Journal of Cardiothoracic Surgery
Background Concomitant left atrial appendage exclusion is increasingly performed during cardiac surgery in patients with atrial fibrillation. However, real-world data on procedural variations, closure integrity, and early safety are limited.

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, EarlyView.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.
