What is the goal of IABP treatment?
The primary goal of IABP treatment is to improve the ventricular performance of the failing heart by facilitating an increase in myocardial oxygen supply and a decrease in myocardial oxygen demand.
What is the decision to initiate An IABP support?
The decision to initiate an IABP support is usually at the discretion of the interventional cardiologist and the advanced heart failure specialist after taking into consideration the short term and long term prognosis, goals of the care, age, and other comorbidities of the patient that may have an impact on the clinical outcomes.
Who should not have An IABP device?
Patients with end-stage cardiac disease should not be considered for IABP unless as a bridge to ventricular assist device or cardiac transplantation. IABP device placement should be avoided in patients with severe peripheral vascular disease. Percutaneous femoral
What is the primary goal of intra-aortic balloon pump (IABP) treatment?
The primary goal of intra-aortic balloon pump (IABP) treatment is to increase myocardial oxygen supply and decrease myocardial oxygen demand. Decreased urine output after the insertion of IABP can occur because of juxta-renal balloon positioning. Haemolysis from mechanical damage to red blood cells can reduce the haematocrit by up to 5%.
What is the primary goal of IABP?
The primary goal of IABP treatment is to improve the ventricular performance of the failing heart by facilitating an increase in myocardial oxygen supply and a decrease in myocardial oxygen demand.
What is the purpose of an IABP quizlet?
1. Mechanical cardiac assist device that benefits patients with actual or potential life-threatening circulatory problems.
Does IABP increase cardiac output?
IABP treatment during ischaemic rupture of the ventricular septum, increases the mean aortic pressure and cardiac output and decreases the right ventricular and pulmonary wedge pressure.
Which of the following is a contraindication for use of an IABP?
Contraindications to IABP include severe peripheral vascular disease as well as aortic regurgitation, dissection, or aneurysm. The potential benefits of IABP must be weighed against its possible complications (bleeding, systemic thromboembolism, limb ischemia, and, rarely, death).
What is the purpose of the IABP and where is it positioned?
The IABP is placed inside your aorta, the artery that takes blood from the heart to the rest of the body. The balloon on the end of the catheter inflates and deflates with the rhythm of your heart. This helps your heart pump blood to the body.
What is the therapeutic effect of the IABP therapy?
As it relaxes, blood flows into the coronary arteries to bring oxygen to the heart. An IABP allows blood to flow more easily into your coronary arteries. It also helps your heart pump more blood with each contraction. The balloon is inserted into your aorta.
Does IABP increase afterload?
The IABP increases diastolic blood pressure, decreases afterload, decreases myocardial oxygen consumption, increases coronary artery perfusion, and modestly enhances cardiac output. The IABP also provides modest ventricular unloading while also increasing mean arterial pressure and coronary blood flow.
How does balloon pump decrease afterload?
The intra-aortic balloon, by inflating during diastole, displaces blood volume from the thoracic aorta. In systole, as the balloon rapidly deflates, this creates a dead space, effectively reducing afterload for myocardial ejection and improving forward flow from the left ventricle.
What is IABP augmented pressure?
This refers to the point in the cardiac cycle when the chambers have filled with blood at the end of diastole – the chamber walls are building up pressure to start systolic contraction, and this is the point at which the heart is working the hardest.
What is a complication of IABP?
Diabetes, peripheral vascular disease and hypertension, as well as smoking were all identified as risk factors for complications following IABP.
Which of the following is a hemodynamic effect of IABP?
The primary hemodynamic benefits of IABP treatment are diastolic pressure augmentation and afterload reduction (Table 21.3). Diastolic augmentation can increase coronary perfusion pressure, mean arterial blood pressure, and systemic perfusion, although these effects have not been consistently found in all studies.
Why is IABP contraindicated in aortic aneurysm?
The use of an intraaortic balloon pump (IABP) for circulatory support in these patients is traditionally considered contraindicated because of concerns over extension of the residual dissection flap or aortic rupture.
What is the primary goal of IABP?
The primary goal of IABP treatment is to improve the ventricular performance of the failing heart by facilitating an increase in myocardial oxygen supply and a decrease in myocardial oxygen demand. The overall haemodynamic effects of IABP therapy are summarized in Table 1.
How effective is IABP?
IABP is also effective in stabilizing patients with refractory ventricular ectopy after myocardial infarction by increasing the coronary perfusion pressure, reducing ischaemia and trans-myocardial wall stress, and maintaining adequate systemic perfusion.
What is the effect of IAB on myocardial oxygen supply?
The haemodynamic consequence of this is an increase in coronary blood flow and, therefore, myocardial oxygen supply.
Why does IABP cause decreased urine output?
Decreased urine output after the insertion of IABP can occur because of juxta-renal balloon positioning. Haemolysis from mechanical damage to red blood cells can reduce the haematocrit by up to 5%. Suboptimal timing of inflation and deflation of the balloon produces haemodynamic instability.
Why is IABP contraindicated?
It is contraindicated in patients with aortic regurgitation because it worsens the magnitude of regurgitation. IABP insertion should not be attempted in case of suspected or known aortic dissection because inadvertent balloon placement in the false lumen may result in extension of the dissection or even aortic rupture.
What is IABP in myocarditis?
IABP has a role in managing patients with refractory ventricular failure outside the setting of acute myocardial infarction, such as those with cardiomyopathy or severe myocardial damage associated with viral myocarditis. This can aid the progression to more definitive treatments such as ventricular assist device or cardiac transplantation.
What is IABP therapy?
IABP therapy is considered to be a class I indication (ACC/AHA guidelines) for the management of cardiogenic shock not rapidly reversed by pharmacological therapy. 7
What is the primary goal of IABP treatment?
The primary goal of IABP treatment is to improve the ventricular performance of the failing heart by facilitating an. increase in myocardial oxygen supply and a decrease in myocardial oxygen demand. The overall haemodynamic effects. of IABP therapy are summarized in.
Where is the IABP inserted?
IABPs are usually inserted using the Seldinger technique via the femoral artery so that the tip of the catheter is advanced proximally into the aorta. Fluoroscopy is not essential for insertion, so an IABP can be placed emergently.
Does cardiopulmonary bypass cause low cardiac index?
cardiopulmonary bypass may be marked by hypotension and a low cardiac index despite the administration of inotropic. drugs. The use of IABP in this setting decreases LV resistance, increases cardiac output, and increases coronary and. systemic perfusion, facilitating the patient’s weaning from cardiopulmonary bypass.
What is the role of IABP in the heart?
When it relaxes, blood moves inside the coronary arteries and carries O2 to the heart. IABP facilitates blood to move quickly to the coronary arteries. This pump also helps the heart to supply more blood with each contraction.
Where do you put the IABP catheter?
Next, you or your doctor will require to insert a balloon pump catheter into the leg artery. After this, you need to bring it to your aorta. After this, the IABP will start working.
What is an intra aortic balloon pump?
An intra-aortic balloon pump (IABP) is a mechanical machine that rises the oxygen (O2) perfusion to the heart and the heart’s muscle and also increases the blood flow (cardiac output). Increased cardiac output boosts the flow of the coronary blood, which increases the supply of O2 to the heart. An intra-aortic pump is made up ...
What is the purpose of a balloon pump?
1) Balloon. The balloon uses to block the way of blood in the aorta at a specific point in time. That means it must be able to resist the pressure of the heart. It is made of a material that will not break or damage easily. This component of the intra-aortic balloon pump should be biocompatible.
How does systolic deflation affect the heart?
With the help of the vacuum effect, the systolic deflation reduces the afterload and indirectly improves the anterior blood flow to the heart. The pump inflates during the diastole process and boosts the coronary arteries’ blood flow through the retrograde blood flow.
Where is the intra aortic pump located?
An intra-aortic pump is made up of a balloon locates in the aorta (the largest vessel and main arteries in the human body, located just below the heart). As the heart ventricles tighten and release the blood, then IABP deflates. This pump reduces resistance (afterload) behind the heart and increases blood flow forward.
Can an intra aortic balloon pump cause a stroke?
It can also produce blood clots and lead to severe issues like stroke. Sometimes, the balloon can become over-inflated, due to which the aorta ruptured.
History
- Kantrowitz1 described augmentation of coronary blood flow by retardation of the arterial pressure pulse in animal models in 1952. In 1958, Harken2 suggested the removal of some of the blood volume via the femoral artery during systole and replacing it rapidly in diastole as a treatment for left ventricular (LV) failure, so called diastolic augmentation. Four years later, Moulopoulos and …
Basic Principles of Counterpulsation
- Counterpulsation is a term that describes balloon inflation in diastole and deflation in early systole. Balloon inflation causes ‘volume displacement’ of blood within the aorta, both proximally and distally. This leads to a potential increase in coronary blood flow and potential improvements in systemic perfusion by augmentation of the intrinsic ‘Windkessel effect’, whereby potential ene…

Technique of Insertion and Operation
- The IABP device has two major components: (i) a double-lumen 8.0–9.5 French catheter with a 25–50 ml balloon attached at its distal end; and (ii) a console with a pump to drive the balloon. The balloon is made of polyethylene and is inflated with gas driven by the pump. Helium is often used because its low density facilitates rapid transfer of gas from console to the balloon. It is al…
