Abstract:
Lung malignancy extending into left atrium is seen very infrequently. We had a patient with a fast growing symptomatic lung mass and electrocardiogram showing persistent coving ST elevation without any biomarker change. Transthoracic echocardiography showed a large left atrial mass which was fixed to the free walls and extended into the appendage. There was also a large lung mass that was compressing the heart from its lateral aspect. CT-scan of chest corroborated the lung mass & CT-guided FNAC showed small cell carcinoma.
