Pulsus alternans is diagnosed by first palpating the radial or femoral arteries, feeling for a regular rhythm but alternating strong and weak pulses. Next, a blood pressure cuff is used to confirm the finding: the cuff is elevated past systolic pressure and then slowly lowered cuff towards the systolic level.
Percutaneous coronary intervention (PCI) is a minimally invasive non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. [2] The procedure is used to place and deploy coronary stents , a permanent wire-meshed tube, to open narrowed coronary arteries.
With improvement in the physician's experience, radial artery access is now being used with equal efficacy to treat almost every complex coronary artery disease, including acute myocardial infarction, chronic total occlusion, bifurcation coronary artery disease and rotablation. Radial access has also been used successfully to treat peripheral ...
Myocardial stunning or transient post-ischemic myocardial dysfunction is a state of mechanical cardiac dysfunction that can occur in a portion of myocardium without necrosis after a brief interruption in perfusion, despite the timely restoration of normal coronary blood flow.
For patients who had a catheterization at the femoral artery or vein (and even some of those with a radial insertion site), in general recovery is fairly quick, as the only damage is at the insertion site. The patient will probably feel fine within 8 to 12 hours after the procedure, but may feel a small pinch at the insertion site.
Chest pain with features characteristic of cardiac origin (angina) can also be precipitated by profound anemia, brady-or tachycardia (excessively slow or rapid heart rate), low or high blood pressure, severe aortic valve stenosis (narrowing of the valve at the beginning of the aorta), pulmonary artery hypertension and a number of other ...
The utility of the modified Allen's test is questionable, [4] and no direct correlation with reduced ischemic complications of radial artery cannulation have ever been proven. In 1983, Slogoff and colleagues reviewed 1,782 radial artery cannulations and found that 25% of them resulted in complete radial artery occlusion, without apparent ...
This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282. The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
