In which order should these procedures be ranked based on invasiveness, from least to most invasive?

To determine the correct ranking of procedures based on invasiveness from least to most invasive, it's important to understand what each procedure entails.

Cardiac Catheterization is typically the least invasive of the listed procedures. It involves inserting a thin tube into a blood vessel, usually in the arm or leg, and guiding it to the heart. This procedure is often diagnostic and helps to assess heart conditions but does not involve significant surgical alterations.

Angioplasty is next in invasiveness. It involves the use of a balloon that is inserted through a catheter to open up narrowed or blocked arteries, often following cardiac catheterization.

The placement of a Stent follows angioplasty in invasiveness. A stent is a small mesh tube that is placed in the artery during or after angioplasty to keep it open. While it is still minimally invasive, it introduces a foreign object into the body and requires additional procedural steps.

Finally, Coronary Artery Bypass Grafting (CABG) is the most invasive. This surgical procedure involves creating new pathways for blood to flow to the heart by bypassing clogged arteries. It requires opening the chest and is a major surgical intervention, leading to a longer recovery time.

Understanding the nature of these procedures allows for accurate ranking based on invas
