After the balloon inflation/deflation or the deposition of the stent, the placement device/deflated balloon are removed leaving the stent in place. [21] [22] The interventional cardiologist decides how to treat the blockage in the best way during the PCI/stent placement, based on real-time data.
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
Mechanical injury of arterials due to stretching of arterial walls with a balloon catheter results in the recruitment of cells such as monocytes, macrophages, and neutrophils to the site of injury. [ 4 ] [ 5 ] Macrophages in particular express many growth factors, cytokines, and enzymes that facilitate vascular smooth muscle cell migration and ...

Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart.This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks").
Additionally, several other devices can be advanced into the artery via a guiding catheter. These include laser catheters, stent catheters, IVUS catheters, Doppler catheter, pressure or temperature measurement catheter and various clot and grinding or removal devices. Most of these devices have turned out to be niche devices, only useful in a ...
