Novel Fluoroscopic Evaluation of Incorrect Impella Placement.

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Imaging

Background:

• Percutaneous coronary intervention (PCI) is a key treatment for coronary artery disease.
• The Impella device is used to support patients during high-risk PCI, especially those with cardiomyopathy.
• Ensuring correct Impella placement is crucial for device efficacy and patient safety.

Purpose of the Study:

• To describe a novel fluoroscopic technique for assessing Impella catheter placement.
• To highlight potential complications arising from malrotation of the Impella device.

Main Methods:

• A case study of a 65-year-old man with cardiomyopathy and multivessel coronary artery disease undergoing Impella-supported PCI.
• Utilized standard single-plane fluoroscopy and additional non-standard fluoroscopic views to evaluate Impella catheter positioning.
• Identified malrotation of the Impella catheter toward the mitral apparatus.

Main Results:

• Initial assessment with standard fluoroscopy suggested correct Impella placement.
• Additional fluoroscopic views revealed malrotation of the Impella catheter.
• This malrotation was oriented toward the mitral apparatus, posing a risk for complications.

Conclusions:

• Malrotation of the Impella microaxial flow pump catheter can lead to serious complications and suboptimal hemodynamic support.
• This case demonstrates the utility of a novel fluoroscopic technique in accurately evaluating Impella placement.
• This technique can aid in preventing complications associated with incorrect Impella positioning during PCI.
