Cervical spondylosis causing vertebrobasilar insufficiency: a surgical treatment.

Although the most common aetiology of transient vertebrobasilar insufficiency is atherosclerosis, a similar syndrome may occasionally be produced by cervical osteophytes. The possibility of such a remedial lesion makes further investigation mandatory in such patients-especially if symptoms are associated with sudden movements of the head or neck. When vertebral compression results from osteophytes, it can be easily relieved by a minor modification of the usual anterior cervical fusion technique. This method has proved to be quite efficacious in two patients whose case histories are reported.

Occurrence of a left ventricular third heart sound in incompetent mitral heterografts.

Three cases of severe mitral incompetence after heterograft aortic valve replacement are described. In all cases an early third heart sound was recorded on the phonocardiograms. In two cases a prominent early diastolic peak was also recorded on the apex cardiograms. These findings do not support the widely held view that the third heart sound is produced by sudden tautening of the mitral valve structures during the rapid filling phase of the left ventricle.
