[Coronary thrombosis imaging in humans].

Area of Science:

• Cardiology
• Vascular Medicine
• Diagnostic Imaging

Background:

• Coronary thrombosis identification impacts prognosis and treatment.
• Invasive techniques like angioscopy, coronarography, and endocoronary ultrasound are used for diagnosis.
• Understanding the diagnostic capabilities and limitations of each technique is essential.

Purpose of the Study:

• To review the diagnostic utility of various invasive techniques for coronary thrombosis.
• To compare the sensitivity and specificity of angioscopy, coronarography, and endocoronary ultrasound.
• To discuss the potential future role of magnetic resonance imaging.

Main Methods:

• Review of existing literature on diagnostic techniques for coronary thrombosis.
• Analysis of sensitivity and specificity data for angioscopy and coronarography.
• Discussion of limitations of endocoronary ultrasound and potential of MRI.

Main Results:

• Angioscopy demonstrates high sensitivity for thrombus detection (67% unstable angina, 75% myocardial infarction).
• Coronarography offers good specificity but lower sensitivity for coronary thrombosis.
• Endocoronary ultrasound struggles with fresh, non-echogenic thrombus and differentiating old thrombus from plaque.

Conclusions:

• Angioscopy is sensitive but complex; coronarography is specific but less sensitive for coronary thrombosis.
• Current invasive methods have limitations in accurately detecting and characterizing coronary thrombus.
• Magnetic resonance imaging shows promise for future non-invasive detection of recent coronary thrombus.
