Key result
Chemotherapy resolves tumor-induced left atrial compression and concurrent atrial fibrillation in small cell lung cancer.
Why the study?
The relationship between left atrial compression by an extra-cardiac mass and atrial fibrillation is not well characterized.
Case Report (n=1)
Atrial fibrillation can be secondary to left atrial compression by an extra-cardiac mass and may resolve when the mass is treated.
This case report describes a patient who developed palpitations and chest pain and was found to be in atrial fibrillation, which was likely due to the presence of an extra-cardiac mass. This was compressing the left atrium. The mass was related to small cell carcinoma, which decreased significantly in size after chemotherapy. Resolution of the atrial fibrillation correlated temporally with reduction in the size of the mass and alleviation of the left atrial compression.

Ahmed et al. (2016) conducted a case report in Atrial fibrillation (n=1). Left atrial compression was evaluated on Resolution of atrial fibrillation. Left atrial compression by a small cell carcinoma mass was associated with atrial fibrillation, which resolved temporally with reduction in mass size after chemotherapy.
