Heart failure with normal ejection fraction (HeFNEF) causes significant hospital admissions. This review explores therapeutic devices aimed at reducing left atrial pressure to alleviate exertional breathlessness in HeFNEF patients.
Area of Science:
- Cardiology
- Medical Devices
- Heart Failure Research
Background:
- Heart failure with normal ejection fraction (HeFNEF) represents approximately 50% of heart failure admissions.
- The underlying pathophysiology and clear diagnostic criteria for HeFNEF remain incompletely defined, impeding effective treatment development.
- Exertional breathlessness is a primary clinical symptom, often linked to elevated left atrial pressure during physical activity.
Purpose of the Study:
- To review potential therapeutic strategies for HeFNEF, focusing on interatrial communication.
- To discuss percutaneously delivered devices currently under investigation for managing HeFNEF.
Main Methods:
- Review of current research and investigational devices for HeFNEF.
- Focus on devices designed to create an interatrial communication.
- Discussion of percutaneous delivery methods for these devices.
Main Results:
- Identified two distinct percutaneously delivered devices as promising therapeutic options.
- These devices aim to alleviate left atrial pressure, a key factor in HeFNEF symptoms.
Conclusions:
- Interatrial communication is a viable therapeutic concept for HeFNEF.
- Percutaneous devices offer a minimally invasive approach to creating this communication.
- Further investigation into these devices is warranted for effective HeFNEF treatment.
