    Summary
    This summary is machine-generated.

    A rare case of variant angina was caused by a calcified aortic valve mass obstructing coronary arteries. Surgical valve replacement completely resolved the patient's symptoms.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Pathology

    Background:

    • Variant angina pectoris, also known as Prinzmetal's angina, is characterized by coronary artery spasms.
    • Aortic valve disease can present with diverse clinical manifestations, including angina.

    Observation:

    • A patient presented with variant angina due to a pedunculated calcific mass originating from the aortic valve.
    • This mass intermittently obstructed the left coronary ostia, leading to symptoms during attacks.
    • Coronary angiography revealed no signs of atherosclerotic disease.

    Findings:

    • Attacks were associated with significant ST segment elevation and tachycardia.
    • A moderate increase in pulmonary artery pressure was noted during symptomatic episodes.
    • Histopathological examination confirmed a calcified mass on the aortic valve.

    Implications:

    • Surgical aortic valve replacement is an effective treatment for variant angina caused by obstructive aortic valve masses.
    • This case highlights the importance of considering non-atherosclerotic causes of coronary obstruction in angina.
    • Accurate diagnosis and timely surgical intervention can lead to complete symptom resolution and improved patient outcomes.
