What are three diseases that may require the use of an intra-aortic balloon pump?
Why might I need intra-aortic balloon pump therapy?
- Unstable angina.
- Heart attack.
- Certain abnormal heart rhythms.
- Heart failure.
- Heart defects.
What is diastolic augmentation IABP?
Abstract. Treatment with the intraaortic balloon pump (IABP) is the most common form of mechanical support for the failing heart. Augmentation of diastolic pressure during balloon inflation contributes to the coronary circulation and the presystolic deflation of the balloon reduces the resistance to systolic output.
What affects diastolic augmentation?
Heart rate: LV and aortic diastolic filling times are inversely proportional to heart rate; shorter diastolic time produces lesser balloon augmentation per unit time. Aortic compliance: as aortic compliance increases (or SVR decreases), the magnitude of diastolic augmentation decreases.
How long can you stay on a balloon pump?
The catheter connects to a computer that controls the rate of inflation and deflation. While most patients only use the IABP for a few days, it can stay in place for up to a month.
Why is IABP contraindicated in AR?
IABP is normally contraindicated in significant aortic regurgitation (AR). It causes and aggravates pre-existing AR while performing well in the event of mitral regurgitation (MR) .
Does IABP increase blood pressure?
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.
Does blood pressure increase with inspiration?
Systemic blood pressure is not constant but varies slightly from heart beat to heart beat and between inspiration and expiration. Normally, the systolic blood pressure decreases by less than 10 mmHg during inspiration, but a decline of this magnitude is not detectable on examination of the peripheral pulse.
Is a balloon pump a VAD?
The intra-aortic balloon pumps (IABPs) have been the gold standard for minimally invasive circulatory support for 40 years, but they were joined in recent years by percutaneously deployed ventricular assist devices (P-VADs).
