3-Dimensional Images of Mitral Annulus Perforation: An Alien's Mouth

Area of Science:

• Cardiology
• Medical Imaging
• Cardiac Surgery

Background:

• Infective endocarditis can lead to severe cardiac complications.
• Mitral annulus calcification is a common finding in elderly patients.
• Cardiac structure perforation is a rare but critical complication.

Purpose of the Study:

• To describe a unique case of mitral annulus perforation.
• To highlight the utility of 3D transesophageal echocardiography in diagnosing rare cardiac pathologies.
• To illustrate the appearance of a windsock-like perforation.

Main Methods:

• Case report of a patient with infective endocarditis.
• Utilized three-dimensional transesophageal echocardiography (3D-TEE).
• Detailed imaging analysis of the posterior mitral annulus.

Main Results:

• Identified a windsock-like perforation at the posterior mitral annulus.
• The perforation was associated with annular calcification and infective endocarditis.
• 3D-TEE provided striking visualization of the cardiac anatomy, resembling an "alien's mouth".

Conclusions:

• Mitral annulus perforation is a rare complication of infective endocarditis.
• Three-dimensional transesophageal echocardiography is invaluable for visualizing complex cardiac structures and diagnosing rare conditions.
• Early and accurate diagnosis is crucial for patient management.
