Cardio-vocal syndrome - How 'benign' condition can turn 'malignant'?

Cardio-vocal syndrome (also called as Ortner's syndrome) is hoarseness of voice due to compression of left recurrent laryngeal nerve secondary to enlarged cardiac chambers and structures. We present two cases of Ortner's syndrome secondary to atrial fibrillation causing enlargement of left atrium compressing the left recurrent laryngeal nerve, and their clinical outcomes.
