coronary artery bypasses grafting

this article describes coronary artery bypass grafting by avlliath jay akrishnan et al. one of the most common reason for coronary artery bypass grafting is narrowing coronary arteries because of atherosclerosis. atherosclerosis causes chest pain (angina pectoris), myocardial infarction and sudden death. the aim of coronary artery bypass grafting is to release pain, prevention of myocardial inf...

Comparison of the Graft Angles Effects on the Temporal Wall Shear Stress Gradients in the Aorto-Coronary and Coronary-Coronary Bypasses

In this theoretical study, the effect of various types of bypass graft angles on the flow field, has been investigated specially on the temporal Wall Shear Stress (WSS) on the toe, heel and some locations on the bed of the Left Anterior Descending (LAD) artery at the anastomoses areas in the Aorto-Coronary (AC) and Coronary-Coronary (CC) bypasses. Flow fields in both bypasses with angles of...

Impact of restenosis 10 years after coronary angioplasty.

AIMS The aim of the study was to compare the 10-year follow-up results of patients with or without restenosis following single-vessel percutaneous transluminal coronary angioplasty (PTCA). METHODS AND RESULTS A total of 313 patients with successful PTCA (> or = 20% reduction in luminal diameter narrowing without acute complications) and a control angiography 6 months after PTCA were included ...

Interpretation is a theory of approximation of the be— havior of dynamic discrete systems such as the formal seman­ tics ofprograms. Since such behaviors can be characterized by fixpoints, the theory essentially provides constructive and ef— fective methods for fixpoint approximation and checking by abstraction. Non—conventionalapplications of abstract interpretation in— clude the design of hie...
