Key result
Multimodality imaging detects rare left atrial NSCLC metastasis presenting with tachyarrhythmia and dyspnea.
Why the study?
Metastatic involvement of the heart is rare, often asymptomatic, and usually diagnosed only during autopsies, with limited data on clinical presentations and diagnostic approaches.
Case Report (n=1)

Symptomatic cardiac metastasis from lung adenocarcinoma may occur; this Level 5 case leaves open prospective validation of imaging and management.
We describe a man who presented at our institution with tachyarrhythmia and dyspnea. Echocardiography, magnetic resonance imaging (MRI) and computed tomography (CT) of the chest performed during hospitalization revealed a mass within the left atrium. A biopsy of the mass showed a non-small-cell lung cancer, adenocarcinoma G3. Metastatic involvement of the heart is rare; most cases are asymptomatic and diagnosed only during autopsies. Echocardiography, CT scan and MRI are complementary investigations in the evaluation of cardiac lesions. In the setting of cardiac metastatic cancer, all management is palliative.

Stroppa et al. (2011) conducted a case report in Tachyarrhythmia secondary to cardiac metastasis from non-small-cell lung cancer (n=1). Multimodality imaging (Echocardiography, MRI, CT) and biopsy was evaluated. A male patient presenting with tachyarrhythmia and dyspnea was diagnosed with a rare left atrial metastasis from non-small-cell lung cancer using multimodality imaging and biopsy.
