Bovine Vectocardiography: A Comparative Study Relative to the Validity of Four Tridimensional Lead Systems

For spatial vectocardiography to become applicable for cardiac investigation in cattle, it was necessary to develop a reliable standardized electrocardiographic lead system in this species. In this study, four tridimensional lead systems, initially developed in horses, were compared when applied in calves. Fifty seven electrocardiograms were collected. The between-subject variability of the magnitude and angles of the tridimensional P, QRS and T modal vectors obtained by use of each lead system was compared. Reproducibility of vectrocardiographic measurements was analyzed by comparing results obtained in 10 calves within a one day interval. The Holmes semi-orthogonal lead system, giving the lowest between-subject variability and the highest between-day reproducibility, appeared to be the most reliable lead system in order to apply vectocardiography in the bovine species.

Brachiocephalic Arterial Reconstruction

From 1980 to 1990, 18 patients underwent trans-sternal repair for occlusive disease of the brachiocephalic artery. The mean age was 57 years (43-72). Most of the patients were women (n = 10). All but two patients had one or more symptoms related to the stenosis of the brachiocephalic trunk: right-sided upper limb ischemia (n = 7), transient ischemic attacks (n = 8), vertebrobasilar insufficiency (n = 6), left sided minor stroke (n = 1). Only two patients were asymptomatic before operation. Angiography revealed a tight stenosis (n = 14) or an occlusion (n = 3); in one patient it concerned an ulcerated non-stenotic plaque of the brachiocephalic artery. Eleven patients had coexistent involvement of other supraaortic vessels. Angiographically, clinically and intraoperatively, there was evidence of Takayasu arteritis in three female patients. All patients had direct repair by trans-sternal approach. Six patients with short lesions had thromboendarterectomy with patch angioplasty of the innominate artery. In eleven cases, aorto-brachiocephalic bypass grafting was performed. In one patient, aortic calcification precluded proximal anastomosis, and a carotid-to-carotid bypass was done. In five patients, simultaneous revascularization of subclavian (n = 3), left common carotid (n = 2) or internal carotid artery (n = 2) completed the procedure. In one patient, concomitant coronary revascularization was done. There was no operative mortality. Postoperative morbidity was limited to pulmonary infection (n = 2), transient neurologic deficit (n = 1) and renal insufficiency (n = 1). All patients had relief of symptoms. Duplex echo scan confirmed patency of all reconstructions at a mean follow-up of 46 months.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]
