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").
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.
This is a serious condition as it affects the heart's ability to pump blood to the body and thus requires immediate intervention. Arrhythmia - the ablation procedure can result in a new rhythm disturbance in the heart. Patients may also experience a return of the arrhythmia after the procedure, requiring them to undergo further treatment.
Stage A Defined as: At high risk for heart failure but without structural heart disease (defects in the heart from aging, injury, infection, or heart defect at birth), or symptoms of heart failure.
The most serious risks are death, stroke, ventricular fibrillation (non-sustained ventricular tachycardia is common), myocardial infarction (heart attack, MI), and aortic dissection. A heart attack during or shortly after the procedure occurs in 0.3% of cases; this may require emergency coronary artery bypass surgery. [13]
Doctors conduct an electrophysiology study in the hospital's cardiac catheterization laboratory. The next step is pacing the heart, this means he/she will speed up or slow down the heart by placing the electrode at certain points along the conductive pathways of the heart and control the depolarization rate of the heart.
Timing the shock to the R wave prevents the delivery of the shock during the vulnerable period (or relative refractory period) of the cardiac cycle, which could induce ventricular fibrillation. If the patient is conscious, various drugs are often used to help sedate the patient and make the procedure more tolerable.
An external vascular closure device of radial artery following a Cardiac catheterization. The device allows for gradual release of pressure over the puncture site, reducing patient discomfort, until closure is achieved. Prior to the development of VCD's, the main method for closing the femoral artery was manual compression.
