Atrium of stone: A case of confined left atrial calcification without hemodynamic compromise

Area of Science:

• Cardiology
• Nephrology
• Medical Imaging

Background:

• Dystrophic cardiac calcification typically presents extensively, linked to systemic inflammation.
• End-stage renal disease (ESRD) on hemodialysis is a known risk factor for cardiovascular complications.

Observation:

• A rare instance of localized dystrophic calcification solely within the left atrial walls was observed.
• The patient had end-stage renal disease undergoing hemodialysis.

Findings:

• Diagnosis was confirmed using echocardiography and computed tomography.
• Calcification was confined to the left atrium, sparing the mitral valve.
• No significant hemodynamic compromise was detected.

Implications:

• This case expands the understanding of dystrophic cardiac calcification patterns in ESRD.
• Highlights the importance of detailed imaging in diagnosing localized cardiac calcification.
• Suggests that calcification patterns may vary significantly even within the same patient population.
