2. Cardiac catheterization - Wikipedia

   en.wikipedia.org/wiki/Cardiac_catheterization

   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").

3. Coronary catheterization - Wikipedia

   en.wikipedia.org/wiki/Coronary_catheterization

   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.

4. Mitral stenosis - Wikipedia

   en.wikipedia.org/wiki/Mitral_stenosis

   The left heart catheterization, on the other hand, gives the pressure in the left ventricle. By simultaneously taking these pressures, it is possible to determine the gradient between the left atrium and left ventricle during ventricular diastole , which is a marker for the severity of mitral stenosis.

5. Catheterization laboratory - Wikipedia

   en.wikipedia.org/wiki/Catheterization_laboratory

   Cardiac catheterization is a general term for a group of procedures that are performed in the cath lab, such as coronary angiography. Once a catheter is in place, it can be used to perform a number of procedures including angioplasty , PCI ( percutaneous coronary intervention ) angiography, transcatheter aortic valve replacement , balloon ...

6. History of invasive and interventional cardiology - Wikipedia

   en.wikipedia.org/wiki/History_of_invasive_and...

   The history of invasive cardiology begins with the development of cardiac catheterization in 1711, when Stephen Hales placed catheters into the right and left ventricles of a living horse. [1] Variations on the technique were performed over the subsequent century, with formal study of cardiac physiology being performed by Claude Bernard in the ...

7. Percutaneous coronary intervention - Wikipedia

   en.wikipedia.org/wiki/Percutaneous_coronary...

   A heart attack during or shortly after the procedure occurs in 0.3% of cases; this may require emergency coronary artery bypass surgery. [13] Heart muscle injury characterized by elevated levels of CK-MB, troponin I, and troponin T may occur in up to 30% of all PCI procedures. Elevated enzymes have been associated with later clinical outcomes ...

8. Balloon septostomy - Wikipedia

   en.wikipedia.org/wiki/Balloon_septostomy

   Balloon septostomy is the widening of a foramen ovale, patent foramen ovale (PFO), or atrial septal defect (ASD) via cardiac catheterization (heart cath) using a balloon catheter. This procedure allows a greater amount of oxygenated blood to enter the systemic circulation in some cases of cyanotic congenital heart defect ( CHD ).

9. Electrophysiology study - Wikipedia

   en.wikipedia.org/wiki/Electrophysiology_study

   He will guide the (steerable) electrodes to the correct position inside the heart. The electrophysiologist begins by moving the electrodes along the conduction pathways and along the inner walls of the heart, measuring the electrical activity along the way. Doctors conduct an electrophysiology study in the hospital's cardiac catheterization ...
