Cardiac and Pulmonary Vascular Risk Stratification in Liver Transplantation

Area of Science:

• Cardiology
• Hepatology
• Transplant Surgery

Background:

• Cardiovascular disease complications are the primary cause of short-term mortality in liver transplant recipients.
• An aging candidate pool presents increased comorbidities, necessitating thorough cardiac and pulmonary vascular risk assessment.
• Common pretransplant cardiovascular issues include arrhythmias, heart failure, stroke, and coronary artery disease.

Purpose of the Study:

• To highlight the significance of cardiovascular risk stratification in liver transplant candidates.
• To discuss common cardiovascular comorbidities and their impact on post-transplant outcomes.
• To introduce the Cardiovascular Risk in Orthotopic Liver Transplantation (CVRIOT) score for predicting short-term complications.

Main Methods:

• Review of existing literature on cardiovascular complications in liver transplant recipients.
• Analysis of common pretransplant cardiovascular comorbidities and their association with post-transplant outcomes.
• Introduction and explanation of the CVRiot score's utility in risk assessment.

Main Results:

• Cardiovascular disease complications are the leading cause of early mortality.
• Preexisting conditions like arrhythmias, heart failure, stroke, and coronary artery disease are prevalent.
• Valvular heart disease and portopulmonary hypertension pose significant intraoperative risks.

Conclusions:

• Effective cardiovascular risk stratification is essential for optimal donor liver allocation.
• The CVRiot score aids in estimating the risk of cardiovascular complications within the first year post-transplant.
• Addressing cardiovascular comorbidities is critical for improving survival rates in liver transplant recipients.
