title: Cocking of a poppet-disc prosthesis in the aortic position. A cause of intermittent aortic regurgitation.
abstract: Intermittent aortic regurgitation due to cocking is described for the first time after replacement of the aortic valve with a poppet-disc prosthesis. A combination of disc grooving and strut thrombus produced the cocking with resultant aortic regurgitation.
