Diagnostic evaluation of left-sided prosthetic heart valve dysfunction.

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Prosthetic heart valve (PHV) dysfunction is a rare but serious complication.
• Accurate diagnosis of PHV dysfunction is critical for effective treatment planning.
• Current imaging techniques like echocardiography and fluoroscopy have limitations in determining the specific cause of dysfunction.

Purpose of the Study:

• To review the established imaging modalities for detecting left-sided mechanical and biological PHV dysfunction.
• To highlight the complementary role of multidetector-row CT (MDCT) in diagnosing PHV dysfunction.
• To discuss the utility of MDCT in surgical planning for reoperations.

Main Methods:

• Review of established imaging techniques: echocardiography and fluoroscopy.
• Evaluation of multidetector-row CT (MDCT) for diagnosing PHV dysfunction.
• Assessment of cardiac magnetic resonance imaging (CMR) in biological PHV dysfunction.

Main Results:

• Echocardiography and fluoroscopy are standard but sometimes insufficient for specific etiological diagnosis.
• Multidetector-row CT (MDCT) provides valuable additional information for PHV dysfunction diagnosis.
• Cardiac magnetic resonance imaging (CMR) has limited utility for biological PHV dysfunction.

Conclusions:

• MDCT serves as a crucial complementary tool for diagnosing the specific cause of prosthetic heart valve dysfunction.
• MDCT aids in surgical planning for reoperations involving prosthetic heart valves.
• A comprehensive imaging approach, including MDCT, improves diagnostic accuracy and treatment selection for PHV dysfunction.
