The PDA supplies the posterior third of the interventricular septum. The remaining anterior two-thirds is supplied by the left anterior descending artery, which is a branch of left coronary artery. It is typically a branch of the right coronary artery (70%, known as right dominance).
PCI is widely practiced and has a number of risks; [9] however, major procedural complications are uncommon. PCI is performed using minimally invasive catheter-based procedures by an interventional cardiologist, a medical doctor with special training in the treatment of the heart. [10]

Patent ductus arteriosus (PDA) is a medical condition in which the ductus arteriosus fails to close after birth: this allows a portion of oxygenated blood from the left heart to flow back to the lungs from the aorta, which has a higher blood pressure, to the pulmonary artery, which has a lower blood pressure.
Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
Cardiac stress testing is used to determine to assess cardiac function and to disclose evidence of exertion-related cardiac hypoxia. Radionuclide testing using thallium or technetium can be used to demonstrate areas of perfusion abnormalities. With a maximal stress test the level of exercise is increased until the person's heart rate will not ...
The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...
It is the dilation of narrowed cardiac valves (usually mitral, aortic, or pulmonary). Congenital heart defect correction Percutaneous approaches can be employed to correct atrial septal and ventricular septal defects, closure of a patent ductus arteriosus, and angioplasty of the great vessels. Percutaneous valve replacement
