The first coronary care unit in the US was opened at Bethany Medical Center in Kansas City, Kansas by Hughes Day, and he coined the term. [3] [4] Bethany Medical Center is also where the first "crash carts" were developed. [5] Studies published in 1967 revealed that those observed in a coronary care setting had consistently better outcomes. [6]
The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...
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. PCI is considered 'non-surgical ...
Diagram of stent placement. In A, the catheter is inserted across the lesion. In B, the balloon is inflated, expanding the stent and compressing the plaque. In C, the catheter and deflated balloon have been removed. Before-and-after cross sections of the artery show the results of the stent placement. Arterial Stenting 3D Medical Animation
Early Morbidity and Mortality Within 30 days of hospitalization, morbidity and mortality after Bentall procedure are associated with complications stemming from cardiac arrhythmia, pneumonia, acute respiratory distress syndrome (ARDS), sepsis, graft infection, wound infection, neurologic/ cerebrovascular accident and stroke, hemorrhage/ bleeding, myocardial infarction, pericardial effusion ...
These stenotic segments of the coronary arteries arise due to the buildup of cholesterol-laden plaques that form in a condition known as atherosclerosis. [3] A percutaneous coronary intervention, or coronary angioplasty with stenting, is a non-surgical procedure used to improve the blood flow to the heart. [1]
Coronary stents are placed during a coronary angioplasty. The most common use for coronary stents is in the coronary arteries, into which a bare-metal stent, a drug-eluting stent, a bioabsorbable stent, a dual-therapy stent (combination of both drug and bioengineered stent), or occasionally a covered stent is inserted. [1]
Like metal stents, placement of a bioresorbable stent will restore blood flow and support the vessel through the healing process. However, in the case of a bioresorbable stent, the stent will gradually resorb and be benignly cleared from the body, enabling a natural reconstruction of the arterial wall and restoration of vascular function.
