Left ventricle reconstruction and heartmate3 implantation. The "double patch technique"

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Cardiac Reconstruction

Background:

• Heart failure treatment often involves left ventricular assist devices (LVADs).
• The HeartMate 3 is a centrifugal pump LVAD used for myocardial recovery, bridge to transplant, or destination therapy.
• Giant aneurysmal dilatation presents complex surgical challenges in heart failure patients.

Purpose of the Study:

• To describe a novel surgical technique for managing giant aneurysmal dilatation of the left ventricle.
• To evaluate the safety and reproducibility of this technique in a selected patient group.

Main Methods:

• Surgical implantation of a HeartMate 3 left ventricular assist device.
• Left ventricular reconstruction utilizing a double patch technique.
• Employing a patch with an internal bovine pericardium layer for blood contact.

Main Results:

• The bovine pericardium layer of the patch effectively minimizes thrombotic risk.
• The technique allows for the restoration of appropriate ventricular geometry.
• The described method is considered relatively reproducible and safe.

Conclusions:

• The presented surgical technique is a viable option for selected patients with giant aneurysmal dilatation.
• The combination of a high-quality LVAD and double patch reconstruction offers a safe approach.
• Restoration of ventricular geometry is achievable with this method, improving patient outcomes.
