Computed tomography angiography for transcatheter aortic valve replacement.

Area of Science:

• Radiology
• Cardiovascular Imaging
• Medical Technology

Background:

• Transcatheter aortic valve replacement (TAVR) is a key alternative for severe aortic stenosis patients unsuitable for surgery.
• CT technologists are crucial for TAVR patient care.
• Complexities in CT acquisition and postprocessing for TAVR demand specialized technologist knowledge.

Purpose of the Study:

• To detail CT angiography acquisition and postprocessing for TAVR screening from a CT technologist's perspective.
• To provide insights from a single institution's workflow.

Main Methods:

• Detailed description of CT angiography acquisition protocols.
• Explanation of image postprocessing steps for TAVR planning.
• Focus on the technologist's role and responsibilities.

Main Results:

• Identification of critical imaging parameters for TAVR planning.
• Highlighting potential challenges and pitfalls in the CT workflow.
• Emphasis on the importance of standardized imaging approaches.

Conclusions:

• CT image acquisition and postprocessing are fundamental for successful TAVR interventions.
• A detailed, standardized imaging strategy is clinically essential for TAVR patients.
• Attention to clinical detail, protocols, and workflow factors ensures optimal patient outcomes.
