Development of a Framework for the Hemodynamic Impact of Positive End-Expiratory Pressure in Normal and Heart Failure Conditions.

Positive end-expiratory pressure (PEEP) improves respiratory conditions. However, the complex interaction between PEEP and hemodynamics in heart failure patients makes it challenging to determine appropriate PEEP settings. In this study, we developed a framework for the impact of PEEP on hemodynamics considering cardiac function, by integrating the impact of PEEP in the generalized circulatory equilibrium framework, and validated the framework by assessing its ability to accurately predict PEEP-induced hemodynamics.

Background: Conduction system pacing (CSP) has been reported to improve clinical outcomes in comparison of right ventricular pacing (RVP). However, the performance between CSP and RVP on the risk of new-onset atrial fibrillation (AF) remains elusive.
Methods: Four online databases were systematically searched up to July 1, 2024.

Structural, architectural, contractile or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodeling has become a cornerstone diagnostic and prognostic marker. The structure and the function of LA and left atrial appendage (LAA) which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation (AF), cardioembolism, heart failure and mitral valve diseases.

This case report discusses the management of a 75-year-old man who developed an unusual type of atypical atrial flutter following a previous pulmonary vein isolation for paroxysmal atrial fibrillation. Despite a second attempt to re-isolate the pulmonary veins and performing cavotricuspid isthmus ablation (which was suspected to be part of the arrythmia circuit), the flutter continued and was converted to sinus rhythm through electrical cardioversion. A few weeks later, the patient's atrial tachycardia relapsed.
