Implication

Supports noninvasive CMR and echo for endomyocardial fibrosis diagnosis; extends evidence for their diagnostic accuracy.

Key Points

Left ventricular dysfunction is identified with a high B-type natriuretic peptide level of 777 ng/mL, signaling heart distress.
Echocardiography reveals myocardial hypertrophy and cavity obliteration in both ventricles, indicating severe cardiac impairment.
Assessment using cardiovascular magnetic resonance confirms biatrial enlargement and biventricular dysfunction, highlighting disease complexity.
These findings stress the importance of identifying endomyocardial fibrosis early to improve patient outcomes; further studies are warranted.

Structured PICO

Population

A 65-year-old woman presenting with exertional dyspnea, palpitations, bilateral jugular vein distension, and mild lower-extremity edema.

Intervention

Cardiovascular magnetic resonance (CMR) and echocardiography

Outcome

Identification of endomyocardial fibrosis imaging characteristics

Cardiovascular magnetic resonance and echocardiography are effective in identifying the characteristic apical obliteration and 'Double V' sign of endomyocardial fibrosis.
