Off-pump myocardial revascularization with Impella 5.5-assisted for cardiogenic shock

Area of Science:

• Cardiology
• Cardiac Surgery
• Mechanical Circulatory Support

Background:

• Acute myocardial infarction with cardiogenic shock presents a critical challenge requiring immediate intervention.
• Off-pump coronary artery bypass grafting (OPCAB) offers benefits but can be complex in severe cases.
• Mechanical circulatory support devices can stabilize patients during high-risk cardiac procedures.

Observation:

• A patient with acute myocardial infarction and cardiogenic shock underwent emergent surgery.
• An Impella 5.5 percutaneous left ventricular assist device was inserted to provide hemodynamic support.
• Off-pump coronary artery bypass grafting was performed, accessing all three walls of the heart.

Findings:

• The Impella 5.5 device facilitated successful off-pump coronary artery bypass grafting in a patient with three-vessel disease.
• The percutaneous left ventricular assist device remained stable throughout the perioperative period.
• This demonstrates the feasibility of combining Impella 5.5 support with OPCAB in complex acute myocardial infarction scenarios.

Implications:

• Impella 5.5 assistance may be a viable strategy for high-risk patients undergoing OPCAB.
• This approach could improve outcomes for patients with acute myocardial infarction and cardiogenic shock.
• Further research is warranted to explore the broader application of this technique.
