Right Heart Failure in Pulmonary Hypertension

Area of Science:

• Cardiology
• Pulmonary Medicine
• Critical Care Medicine

Background:

• Right heart failure is a significant contributor to morbidity and mortality in patients with pulmonary hypertension.
• The pathophysiology involves intricate adaptive and maladaptive changes in the right ventricle.
• Accurate diagnosis and risk stratification are crucial for effective management.

Purpose of the Study:

• To summarize the current understanding of right heart failure in pulmonary hypertension.
• To highlight diagnostic modalities and risk assessment tools.
• To outline current and emerging management strategies.

Main Methods:

• Review of current literature on right heart failure and pulmonary hypertension.
• Discussion of diagnostic techniques including right heart catheterization and echocardiography.
• Analysis of therapeutic approaches, including medical management and mechanical circulatory support.

Main Results:

• Right ventricular adaptation to pulmonary hypertension can be both beneficial and detrimental.
• Echocardiography provides valuable noninvasive insights for diagnosis and risk stratification.
• Management strategies aim to optimize hemodynamics and support right ventricular function.

Conclusions:

• Right heart failure is a complex clinical challenge in pulmonary hypertension.
• A multi-faceted approach combining diagnostics and tailored therapies is essential.
• Mechanical support offers a vital option for select patients, aiding recovery or serving as a bridge to transplant.
