Abstract

Coronary heart disease (CHD) is one of the leading causes of mortality worldwide. It is primarily caused by myocardial ischemia and hypoxia resulting from atherosclerotic plaques in the coronary arteries, leading to symptoms such as angina. The severity of CHD determines the treatment approach, which may include medication or interventional therapy. Therefore, accurately assessing the severity of myocardial ischemia is crucial for effective CHD management. In recent years, fractional flow reserve (FFR), derived from the relationship between flow and pressure, has gained widespread recognition for providing valuable information to guide coronary revascularization. Pressure guidewires equipped with pressure sensors at their tips are the most commonly used tools for clinical FFR assessment. These wires measure vessel pressure to determine the severity of coronary lesions. However, during their use, issues such as signal drift, tip breakage, core wire fractures, and coating detachment may occur. This article reviews the historical development of pressure guidewires, examines the general structure of two commonly used pressure guidewires available in the market, highlights typical issues encountered during clinical use, and proposes corresponding solutions.

期刊介绍: Catheterization and Cardiovascular Interventions is an international journal covering the broad field of cardiovascular diseases. Subject material includes basic and clinical information that is derived from or related to invasive and interventional coronary or peripheral vascular techniques. The journal focuses on material that will be of immediate practical value to physicians providing patient care in the clinical laboratory setting. To accomplish this, the journal publishes Preliminary Reports and Work In Progress articles that complement the traditional Original Studies, Case Reports, and Comprehensive Reviews. Perspective and insight concerning controversial subjects and evolving technologies are provided regularly through Editorial Commentaries furnished by members of the Editorial Board and other experts. Articles are subject to double-blind peer review and complete editorial evaluation prior to any decision regarding acceptability.
