Minimally invasive ventricular assist device implantation

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Medical Devices

Background:

• Mechanical circulatory support (MCS) is crucial for end-stage heart failure, especially with donor organ scarcity.
• Left ventricular assist devices (LVADs) are a key MCS therapy.
• Traditional LVAD implantation uses median sternotomy (MS).

Purpose of the Study:

• To review current less-invasive LVAD implantation techniques.
• To highlight advantages of minimally invasive approaches over MS.
• To focus on centrifugal pumps in less-invasive LVAD procedures.

Main Methods:

• Review of existing literature on LVAD implantation strategies.
• Analysis of minimally invasive techniques, defining their characteristics (e.g., reduced trauma, preserved pericardium).
• Comparison of less-invasive methods with traditional sternotomy.

Main Results:

• Less-invasive LVAD implantation strategies aim to minimize surgical trauma and cardiopulmonary bypass complications.
• These approaches often avoid sternal splitting and extensive pericardial manipulation.
• There is no universal consensus on the optimal LVAD implantation method.

Conclusions:

• Minimally invasive LVAD implantation is a viable alternative to sternotomy.
• Centrifugal pumps are increasingly utilized in these less-invasive procedures.
• Further research and standardization of less-invasive techniques are warranted.
