摘要:

The current method of analyzing coronary flow data is the TIMI flow grade method. This method is convenient and easy to apply, but there are limitations to this categorical method of analyzing coronary artery flow. We have developed a new method of analyzing coronary blood flow called the “TIMI frame count.” Using the TIMI frame counting method, we have shown that the flow in the coronary arteries is in fact distributed as a continuous variable and that there are nondiscrete categories of slow and fast flow. This article discusses the statistical basis for the development of this new, simple, and continuous index of coronary flow and provides a “how‐to manual“ describing the practical implementation of the new TIMI frame count method. We also describe simple new techniques for measuring the distance to the landmark used for TIMI frame counting. Knowing the distance and the time from the TIMI frame count, velocity can easily be calculated. Tables are provided that can be used for these calculations on‐line in the cardiac catheterization laboratory. If the diameter is known, flow can also be calculated from these tables. We also describe new applications of marker wires to measure distance a

摘要:

Based on the experience of our in vitro examination to assess the stents for a safe and effective angioplasty through the struts, a Palmaz‐Schatz stent was implanted easily and completely from the left main trunk to the left anterior descending coronary artery through the struts of a Wiktor stent implanted from the left main trunk to the circumflex artery in two case

摘要:

We describe a patient with dextrocardia and angina pectoris in whom balloon angioplasty in the right coronary artery resulted in an obstructive dissection. Emergency bypass surgery was avoided by the successful placement of a stent (Palmaz‐Schatz

摘要:

A 62‐year‐old man sustained an anterior wall myocardial infarction 7 years following coronary artery bypass graft surgery. The patient underwent successful placement of a Palmaz‐Schatz stent within the ostium of the left internal mammary artery utilizing ultrasound guidance and was discharged in 24 hours with reduced anticoagul

摘要:

New devices for catheter‐based coronary revascularization provide substantial economic and ethical challenges. It is important for new technologies to undergo rigorous evaluation, and for the outcome assessment to include long‐term follow‐up. The outcome should include medical resource use and economic end points, as well as the traditional clinical measures, so that the cost‐effectiveness of new technology can be assessed. Society must strike a balance between uncontrolled proliferation of new technology and the stifling of innovation by restrictive regulatory and reimbursement policies. The clinical investigator and interventional cardiologist must be aware of the potential of new technology to pose ethical dilemmas, and establish checks and balances to protect against
