Insights

The growing population of left ventricular assist device (LVAD) patients faces challenges with both bleeding and clotting. New prompt percutaneous therapies are needed to manage these complex complications and stabilize patients.

Area of Science:

  • Cardiology
  • Biomedical Engineering

Background:

  • The number of heart transplants is limited by donor availability, leading to an increasing reliance on left ventricular assist devices (LVADs).
  • Patients are living longer with LVADs for bridge-to-transplant or destination therapy, increasing the incidence of device-related complications.

Observation:

  • Physicians frequently encounter patients with concurrent bleeding and thrombotic complications.
  • Managing anticoagulation in LVAD patients is challenging; reducing it for bleeding increases thrombosis risk, while pump thrombosis has limited non-surgical treatment options.

Findings:

  • Surgical pump exchange is the definitive treatment for pump thrombosis but carries high risks.
  • Temporary LVAD deactivation can lead to rapid patient decline due to retrograde flow.

Implications:

  • There is a critical need for prompt, effective percutaneous therapies to manage bleeding and thrombosis in LVAD patients.
  • Developing new strategies is essential for improving outcomes and patient stability in this growing population.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
