4 components make up a congenital anomaly: 1. pulmonary artery stenosis; 2. interventricular septal defect; 3. aortic transposition, in which both ventricles empty into the aorta; 4. right ventricular hypertrophy due to increased workload of the right ventricle angiography, in which two radiographic images are obtained, one without contrast material and the other after contrast material has been injected, and then c

In patients at risk of sudden cardiac death, an automatic implantable cardioverter-defibrillator (AICD) is implanted. It is a battery-powered system that detects and automatically corrects ventricular tachycardia or fibrillation by transmitting electrical impulses to the heart.
A nuclear technique that uses radioactive tracers to detect how well the heart walls shift as they contract and measures the ejection fraction rate is known as a multiple-gated acquisition (MUGA) scan (amount of blood the ventricle can pump out in one contraction)

Aorta abdominalis

Left main and complex bifurcations stenting – europcr 2019

The main branches of the aorta within the abdominal cavity, reaching from the diaphragm to the pelvis, supply the major vital organs, including the entire gastrointestinal tract, liver, and kidneys.
Aortic aneurysm in the abdomen
The abdominal aorta, the body’s largest artery, dilates (balloons) to more than 50% of its natural diameter in all three layers. The most common form of true artery aneurysm; rupture causes life-threatening internal bleeding.
AneurysmAneurysm is a “ballooning” of a blood vessel, normally an artery, caused by plaque weakening the artery wall, which then causes the artery to swell out and the artery wall to become dangerously small.
Angiography is a form of angiography that involves
Angiograms are images created by injecting a special dye (or other contrast material) into blood vessels to help visualize disease and blood flow.
Angioplasty is a procedure in which a balloon-tipped catheter is inserted into a blocked artery and inflated to compress plaque against the artery wall, reopening the narrowed artery.

Coronary microvascular dysfunction: why diagnosis in the

Fainting (syncope) is a brief loss of consciousness in which a person collapses to the ground or slumps in a chair before regaining consciousness. Anything harmful or relatively harmless may be the cause of fainting. Which of the following classes has the most dangerous causes of fainting?
Between the left ventricle and the aorta is where the aortic valve is found. When the left ventricle contracts to pump blood into the aorta, the aortic valve opens. The valve opening is narrowed when the valve flaps become thick and rigid due to a disease (stenosis). When the left ventricle relaxes, the stiffened valve often fails to close fully, allowing blood from the aorta to leak back into the heart (aortic regurgitation).
The muscular wall of the left ventricle thickens as the ventricle works harder to pump blood into the narrowed valve opening into the aorta in aortic stenosis. The thickened heart muscle requires a greater supply of blood from the coronary arteries, and the blood supply does not always meet the needs of the heart muscle, particularly during exercise. Inadequate blood flow can result in chest pain, fainting, and even sudden death. The heart muscle can deteriorate, resulting in heart failure. Infection of the abnormal aortic valve is unusual (infective endocarditis).
