Coronary endarterectomy during off-pump coronary artery bypass surgery.

Coronary endarterectomy (CEA) is often combined with coronary artery bypass grafting (CABG), which is performed on cardiopulmonary bypass (CPB). Recent advances in off-pump surgical technique and cardioanesthesiology, along with the increasing number of patients with high risk of CPB complications made it possible and desirable to execute CEA on a beating heart. Russian scientific literature lacks reports on these interventions.

[Changes in the ultrastructure and DNA and protein content in human atrial myocytes in cardiac hyperfunction due to mitral valve defects].

Biopsies from human right auricles were obtained during open heart surgery, prior to valve replacement, from six patients (aged from 20 to 49 years) with rheumatic heart disease. DNA and the total protein contents were measured in isolated myocytes by means of the two wave-length scanning cytophotometry after the double Feulgen and Naphthol yellow S staining procedure. In all the biopsies polyploid hypertrophied myocytes predominate.
