How does an intra aortic balloon pump function?

How does an intra aortic balloon pump function?

Counterpulsation: The iabp fills with helium during diastole, forcing blood in the aorta to circulate around the body and then deflates quickly during systole, making it easier for the left ventricle to eject blood. ...Read more

Aorta (Definition)

The aorta is the largest artery in the body, leaving directly from the left ventricle of the heart to supply blood to the entire body. It is made of elastic tissue layers called "intima" and is subject to damage by high blood pressure, smoking, cholesterol, ...Read more

How does an intra-aortic balloon pump work?

How does an intra-aortic balloon pump work?

Intra-aortic pump: during diastole ( when the heart relaxes), the pump is inflated forcing blood to the coronary arteries, and during systole ( when the heart contract), the balloon pump deflates allowing blood to past through the aorta, the pump is used to facilitate myocardium ( heart muscle) oxygenation after severe myocardial infarction ( heart attack) ...Read more

Is mod to sever aorta stenosis with peak/mean pressure gradient of 57.06mmhg/37.30mmh requiring aorta valve replacement stat?

Is mod to sever aorta stenosis with peak/mean pressure gradient of 57.06mmhg/37.30mmh requiring aorta valve replacement stat?

It could be: It depends upon whether symptoms are present. If the aortic stenosis is causing chest pain, congestive heart failure, shortness of breath or blackouts then this is usually regarded as a reason for prompt treatment. If there are no symptoms then watchful waiting is sometimes appropriate. BTW some patients in this age group qualify to have the valve implanted through a catheter via the groin. ...Read more

Is coronary artery bypass surgery compatible with varicose veins?

Is coronary artery bypass surgery compatible with varicose veins?

Yes and No: Coronary artery bypass requires some form of conduit for bypass. Superficial veins from the lower limbs have been used for bypass. Smaller arteries from the underside of the chest wall have been used in favor of veins for the left side of the heart. Early enlarged varicose veins can still be used for bypass; however more advanced wall bulges and wall aneurysms Prohibit use of the varicosed veins. ...Read more

When shoud heart artery stenoses be stented or bypassed?

When shoud heart artery stenoses be stented or bypassed?

Depends: When blood flow is sufficiently reduced by a greater than 70% blockage of an artery or arteries, to the point of permanent damage or weaknening of the heart muscle, or when a plaque ruptures and a blood clot repeatedly forms with resulting blockage of blood flow, then an artery needs to be stented, or bypassed. ...Read more

When are aortic aneurysm repairs performed?

When are aortic aneurysm repairs performed?

Based on size: The risk of rupture of an aortic aneurysm increases with its size (diameter). When the size reaches a certain threshold, the risk of rupture becomes substantial. At this point, a repair is justified either with surgery or a percutaneous stent graft. ...Read more

Is CABG (coronary artery bypass grafting) an open heart surgery or closed heart surgery?

Is CABG (coronary artery bypass grafting) an open heart surgery or closed heart surgery?

Not necessarily: A CABG if done without cardiopulmonary bypass (cpb) does not require the heart to be opened, however most cabgs are done with cpb requires cannula placement in the heart. However, most people consider any surgery on the heart where the chest is opened open heart surgery. ...Read more

Could bilateral internal thoracic artery grafting increase surgical risk?

Could bilateral internal thoracic artery grafting increase surgical risk?

Not always : There is some evidence that in diabetic patients it can increase the risk of eternal wound infections. Not in non diabetics. This increase risk in diabetics has been debated and there is some recent data suggesting that it may not be true. ...Read more

Does a right atrium dilated, RV pressure of 25-30 mHg, IVC dynamics 5-10 mmHg subjective possibly of pulmonary hypertension or heart failure?

Does a right atrium dilated, RV pressure of 25-30 mHg, IVC dynamics 5-10 mmHg subjective possibly of pulmonary hypertension or heart failure?

If accurate, only: mildly ?ed. RA ~10 mmHg, RV systolic ~25 mmg Hg generally ~optimally healthy; similar to the values stated. Thus RA enlargement likely: mismeasurement (common, not rare; study image data yourself), marked tricuspid regurgitation, congenital variant, atrial muscle problem [eg advanced arterial disease in RA arteries; (lumens too small to see by angiography) producing RA ischemia/fibrosis], etc. ...Read more

Result of Angiography: three vessel coronary artery desease. preserved LV systolic function.what is best FOR MEAngioplasty or bypass operation?

Result of Angiography: three vessel coronary artery desease. preserved LV systolic function.what is best FOR MEAngioplasty or bypass operation?

Depends: If you're diabetic, CABG has better outcomes. If your LEFT MAIN coronary artery has >50% blockage, CABG has better outcomes. Aside from those 2 points, it depends on the skill of the team you have. If they do a lot of angioplasty, that would be preferred. If they don't but their surgical team is first rate, then that would be preferred. ...Read more

During coronary angioplasty how are catheters inserted into the femoral artery to the heart?

During coronary angioplasty how are catheters inserted into the femoral artery to the heart?

Depends: Depending on the arterial access , a single IV like catheter is placed called an arterial sheath. All catheters are fed thru the sheath using a j-shaped guide wire. Most sheaths are placed in the femoral artery others in the radial arteries. All arteries lead back to the heart in a retrograde fashion and the catheter is manipulated into the artery of intrest for repair with angioplaty and stent. ...Read more

My cardiac MRI showed persistent left sided superior vena cava drains into a dilated coronary sinus w/ mild dilation of the main pulmonary artery?

My cardiac MRI showed persistent left sided superior vena cava drains into a dilated coronary sinus w/ mild dilation of the main pulmonary artery?

Mostly a normal: Variant. Every fetus has one, but in most it involutes before birth. 0.3% of the general population has one. It is the most common variation of the thoracic venous system. Left svc draining into coronary sinus is expected 90% of the time. Discuss with your doctor the significance in your case of the mild dilation of the pulmonary artery. ...Read more

Is having a leaking aortic valve related to an aortic aneurysm?

Is having a leaking aortic valve related to an aortic aneurysm?

Sometimes: Thoracic aortic enlargement and aneurysm can dilate the aortic valve annulus and leakage can occur. Also with aortic valvular stenosis, post stenotic dilation can occur. Abdominal aneurysms are not usually related to valve issues. ...Read more
