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").
The transfemoral (through groin) approach to perform cardiac catheterization has typically been more prevalent in invasive cardiology. But radial access has gained popularity due to technical advances with catheters and lower complication rates than transfemoral access. [ 1 ]
A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures.
Once the wire is across, a large tube is used to place the transcatheter heart valve through the femoral vein and inferior vena cava into the aorta and from there the heart. This otherwise resembles the transfemoral approach. Afterwards, the hole in the aorta is closed with a self-collapsing nitinol device designed to close holes in the heart ...
A, the catheter/DES device is inserted across the lesion. B, the balloon is inflated using saline fed through the catheter portion into the DES/Balloon component, expanding the DES and compressing it against the artery wall. C, the catheter and deflated balloon removed leaving the DES firmly embedded in the artery wall.
An incision is made in the groin, wrist, or arm, and a catheter is inserted into the artery through it. An X-ray is used to guide the catheter to the area of blockage. A dye is inserted through the catheter to make the places of blockage visible. When the catheter is in position, a thin wire with a balloon is guided to the place of blockage.

Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
