The word Angiography reminds of the graph with haphazard lines going up and down with the pulse rate of the heart. But angiography has nothing to do with graphs. It is medical photography in simple terms. Medically, it is an imaging technique using X-ray examination of blood vessels or heart chambers including veins and arteries.
The roots of this word can be traced back to Greek language with angeion meaning ‘vessel’ and graphein meaning ‘to write or record’. The process is called angiography or arteriography and the image is called angiograpgh or angiogram. This technique was first developed in 1927 by Portuguese physician and neurologist Egas Moniz.
The percentage of complications in coronary angiography is as low as 1 in 1000. Death, myocardial infarction, stroke serious ventricular arrhythmia, and major vascular complications each occur in less than 1% of patients undergoing catheterizations. These include Cardiac arrhythmias, kidney damage, blood clots (which can cause heart attack or stroke), hypotension and pericardial effusion and many more. Whatever may be the complications, the improved technology leaves negligible scope for error. The improved technology not only includes machines but also virtual online doctors who help us in many different ways.
