    Calcific emboli were found in 45% of hearts with severe left heart valve calcification. These emboli, particularly in the coronary arteries, are linked to mitral valve disease and ischemic heart symptoms.

    Area of Science:

    • Cardiology
    • Radiology
    • Pathology

    Background:

    • Advanced calcification of heart valves is a common condition.
    • Spontaneous calcific emboli can arise from diseased heart valves.
    • The clinical significance of these emboli is not fully understood.

    Purpose of the Study:

    • To investigate the presence and extent of spontaneous calcific emboli in hearts with advanced left heart valve calcification.
    • To determine the association between calcific emboli and specific valvular heart diseases.
    • To assess the relevance of coronary calcific emboli in patients with ischemic heart disease symptoms.

    Main Methods:

    • Examination of 31 hearts with advanced calcification of one or both left heart valves.
    • Utilized X-ray (Mammograf) to detect and quantify calcific emboli.

  • Analyzed the location and distribution of emboli within the coronary and systemic circulation.

    • Main Results:

    • Calcific emboli were detected in 45% of the studied hearts.
    • Intracoronary emboli were found in 14 cases (45%), with 205 intracoronary emboli identified.
    • Calcific particles were present in the left ventricular cavity in 23% of cases, with 60 intravenous emboli identified.
    • Embolization was most frequent and extensive in cases of postrheumatic mitral valve disease.

    Conclusions:

    • Spontaneous calcific emboli are a frequent finding in hearts with advanced left heart valve calcification.
    • Coronary calcific emboli are associated with valvular heart disease, particularly mitral valve disease.
    • Coronary calcific embolization should be considered in the differential diagnosis of ischemic heart disease in patients with valvular lesions.
