Risks And Complications

The overall risk for complications from cardiac catheterization is about 1 in 1000. Contrast dyes cause adverse effects in almost 1 out of 10 patients. The common side effect is nausea or vomiting. Some of the complications due to dye allergy are -

Fast heartbeat
Slow heartbeat
Nausea
Vomiting
Shock
Kidney failure
Epilepsy
Itching
Rashes

Few other complications are -

Bleeding at the insertion site
Damage to the blood vessels used for catheter entry
Infection
Ventricular arrhythmias
Pneumothorax [air collection between the chest wall and the lungs]
Cardiac tamponade [fluid collection around the heart]
Heart attack
Stroke [0.1%]
Air embolism
Death [0.1- 0.2%]

In rare cases, patients undergoing angiogram will be shifted to the operation room for an emergency bypass surgery.
