Coronary-subclavian steal

Archives of Surgery
D H Tyras, H B Barner


Of 450 patients undergoing internal mammary artery grafts for coronary artery bypass, proximal subclavian artery stenosis with reversal of flow in the internal mammary and vertebral arteries ("coronary-subclavian steal") subsequently developed in two patients. Carotid-subclavian bypass successfully reestablished antegrade blood flow in the ipsilateral internal mammary and vertebral arteries in both patients. Arch aortography is indicated preoperatively in myocardial revascularization patients in the presence of cerebrovascular symptoms, upper extremity blood pressure gradients, and carotid or subclavian bruits. Should subclavian artery stenosis develop subsequent to myocardial revascularization, carotid-subclavian or acillary-axillary bypass can effectively restore antegrade blood flow and reverse the coronary-subclavian steal.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.


Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
