Right Ventricle-Pulmonary Artery Coupling in Patients Undergoing Cardiac Interventions

Area of Science:

• Cardiovascular Physiology
• Medical Imaging
• Cardiac Surgery

Background:

• Right ventricular-pulmonary artery (RV-PA) coupling is crucial for cardiovascular health.
• Accurate assessment of RV-PA coupling is vital in managing complex cardiac conditions.

Purpose of the Study:

• To review the fundamentals of RV-PA coupling.
• To discuss non-invasive measurement techniques for RV-PA coupling.
• To summarize current understanding of RV-PA coupling in cardiac surgery, interventions, and congenital heart disease.

Main Methods:

• Review of existing literature on RV-PA coupling.
• Investigation of non-invasive assessment tools like cardiac MRI and echocardiography.
• Analysis of right-sided pressure measurements.

Main Results:

• Development and validation of non-invasive surrogates for RV-PA coupling.
• Studies focus on patients undergoing cardiac surgery/interventions and those with congenital heart disease.
• Research aims to establish cut-off values for predicting morbidity and mortality.

Conclusions:

• Accessible clinical evaluation of RV-PA coupling is a growing area of research.
• Validated surrogates are essential for integrating RV-PA coupling assessment into perioperative practice.
• This evidence supports improved patient management in cardiac surgery and congenital heart disease.
