Background: Advanced heart failure is associated with recurrent congestion, hospitalization, reduced quality of life, and high mortality. Hemodynamic monitoring technologies help detect worsening filling pressures before symptoms become severe.

Objective: To review invasive, implantable, wearable, and non-invasive hemodynamic monitoring technologies used in advanced heart failure and evaluate their clinical utility, outcomes, and safety.

Methods: This narrative review summarizes contemporary evidence, device principles, patient selection, clinical workflows, benefits, limitations, and future directions of hemodynamic monitoring in advanced heart failure.

Results: Pulmonary artery pressure monitoring, remote device-based diagnostics, echocardiography, right heart catheterization, bioimpedance, wearable sensors, and artificial intelligence–assisted platforms can improve congestion detection and guide therapy. Implantable pulmonary artery pressure sensors have shown reductions in heart failure hospitalization in selected patients.

Conclusion: Hemodynamic monitoring is increasingly central to advanced heart failure management. The greatest benefit occurs when monitoring data are integrated into structured clinical response pathways.
