ARTICLE HIGHLIGHTS
Case characteristics

A 64-year-old female with type II diabetes and hypertension presented with worsening dyspnea on exertion that had rapidly progressed from her baseline with orthopnea and paroxysmal nocturnal dyspnea.

Clinical diagnosis

Pulmonary rales, jugular venous distension, and a loud holosystolic murmur radiating to axilla.

Differential diagnosis

New-onset heart failure due to mitral regurgitation vs cardiomyopathy.

Laboratory diagnosis

Elevated troponin and brain natriuretic peptide.

Imaging diagnosis

Transthoracic echocardiogram with ultrasound enhancing agent showed severe functional secondary mitral regurgitation and reduced left ventricle ejection fraction of 30% with inferior wall aneurysm, while delayed enhancement cardiac magnetic resonance imaging (CMR) illustrated a large mural thrombus measuring 3.0 cm x 1.3 cm adherence to the basal inferior wall aneurysm as well as two apical thrombi.

Treatment

Coronary artery bypass grafting, mitral valve replacement, removal of mural thrombus, and resection and plication of ventricular aneurysm.

Related reports

Cardiac magnetic resonance is a well suited imaging modality in detecting left ventricular thrombus due to its high resolution images and is more reproducible than transthoracic echocardiogram.

Experiences and lessons

Delayed-enhancement CMR provides the greatest sensitivity for detection of left ventricular thrombus, superior to standard transthoracic and contrast-enhanced transthoracic echocardiography.
