Innovative transcatheter procedures for the treatment of heart failure

Area of Science:

• Cardiology
• Medical Devices
• Interventional Cardiology

Background:

• Heart failure (HF) prevalence is increasing due to population aging and better survival rates.
• Despite advances in drug therapy, HF morbidity and mortality remain high.
• Non-pharmacologic treatments like ICDs, CRT, and LVADs are standard HF care.

Purpose of the Study:

• To review main devices for HF associated with aortic and mitral valve disease.
• To describe novel transcatheter interventions for chronic HF.
• To highlight treatments targeting different pathophysiologic mechanisms in HF.

Main Methods:

• Review of existing literature and clinical data on HF devices and transcatheter interventions.
• Focus on treatments for valvular heart disease (VHD) in HF patients.
• Discussion of devices for chronic HF with specific pathophysiologic targets.

Main Results:

• Transcatheter aortic valve implantation (TAVI) aids in unloading the left ventricle for aortic stenosis (AS) and severe aortic regurgitation (AR).
• Percutaneous mitral valve repair improves outcomes for functional mitral regurgitation, serving as a bridge to LVAD or transplant.
• Novel devices are being developed for chronic HF treatment.

Conclusions:

• Transcatheter therapies and devices represent significant advancements in managing HF, especially when linked to VHD.
• These interventions offer new strategies to improve quality of life and prognosis for HF patients.
• Further development targets diverse pathophysiologic pathways in chronic HF.
