Structural Heart Interventions in Patients with Left Ventricular Assist Devices

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Interventional Cardiology

Background:

• Left ventricular assist devices (LVADs) have significantly improved survival and quality of life for patients with advanced heart failure (HF).
• Patients with LVADs often present with complex comorbidities and structural heart disease, necessitating specialized care.
• The native heart's function is crucial for LVAD support, making its structural integrity vital.

Purpose of the Study:

• To provide a comprehensive review of diagnosing and treating structural heart disease in patients with LVADs.
• To emphasize the importance of multidisciplinary collaboration between HF cardiologists, surgeons, and interventionalists.
• To highlight individualized transcatheter interventional strategies for LVAD-related complications.

Main Methods:

• Review of current literature and clinical practices regarding structural heart disease in LVAD patients.
• Discussion of diagnostic modalities for identifying LVAD circuit and native heart failures.
• Analysis of transcatheter intervention techniques for specific structural lesions.

Main Results:

• Multiple failure points exist in the LVAD circuit and native heart, including regurgitant valve lesions, interatrial shunts, and outflow cannula obstruction.
• Transcatheter interventions offer tailored solutions for these complex structural heart issues.
• Successful management requires a collaborative, individualized approach.

Conclusions:

• Structural heart disease poses significant risks in LVAD patients, impacting morbidity and mortality.
• Early diagnosis and prompt, tailored transcatheter interventions are key to improving outcomes.
• Multidisciplinary collaboration is essential for optimizing care in this complex patient population.
