Key result
Global longitudinal strain on transthoracic echocardiography successfully localized a 2.7 x 2.3 cm intramyocardial metastasis in a patient with renal cell carcinoma, which was subsequently confirmed by cardiac magnetic resonance imaging.
Why the study?
There are limited reports of using global longitudinal strain on transthoracic echocardiography to identify intracardiac masses in cardio-oncology patients.

No
Reduced regional global longitudinal strain on transthoracic echocardiography can identify and localize intracardiac metastases, prompting confirmatory multimodality imaging.
Reduced regional strain on TTE may localize intracardiac metastases; extends strain imaging utility but remains hypothesis-generating.
Transthoracic echocardiography and global longitudinal strain are pivotal in evaluating myocardial structure and function in cardio-oncology patients, but there are limited reports of using global longitudinal strain to identify intracardiac masses. This case presents a patient with metastatic renal cell carcinoma and cardiac metastasis that was identified using global longitudinal strain on transthoracic echocardiography and subsequently confirmed by cardiac magnetic resonance imaging.

West et al. (2026) conducted a case report in Metastatic renal cell carcinoma with cardiac metastasis (n=1). Global longitudinal strain (GLS) on transthoracic echocardiography was evaluated on Detection and localization of intracardiac mass. Global longitudinal strain on transthoracic echocardiography successfully localized a 2.7 x 2.3 cm intramyocardial metastasis in a patient with renal cell carcinoma, which was subsequently confirmed by cardiac magnetic resonance imaging.
