Q
A year after having a stroke, I was finally diagnosed with a rare aortic valve defect called Lambl’s excrescence. It showed up on an echocardiogram, but four specialists didn’t know what it was or felt it wasn’t the cause of the clots in my brain. They thought the cause was sporadic atrial fibrillation. I finally went to an electrophysiologist for a second opinion, and he said the clots likely came from the defect. I’d like to hear what you have to say about Lambl’s excrescence.
