The Evaluation of Survival in Patients Who Need Intra Aortic Balloon Pump (IABP) after Cardiac Surgery

Introduction: Insome cases, assist devices are required to ensure an adequate cardiac output after cardiac surgery. Intra-aortic balloon pump (IABP) is the most commonly used cardiac assist device, which provides first-line support for patients with heart failure. The aim of this study was to determine factors affecting the mortality rate of patients receiving IABP. Materials & Methods:  In thi...

Biventricular pacing in conjunction with epicardial atrial pacing adversely affects timing of intra-aortic balloon pump.

A case of accidental triggering of an intra-aortic balloon pump during systole is presented. The patient had a cardiac resynchronization therapy device in place preoperatively for heart failure. A temporary epicardial atrial pacing wire was used during separation from cardiopulmonary bypass for rate control. An intra-aortic balloon pump was necessary for separation from bypass. Although the pac...

A randomized comparison of intra-aortic balloon pumping after primary coronary angioplasty in high risk patients with acute myocardial infarction.

AIMS Intra-aortic balloon pumping reduces afterload and may be effective in improving reperfusion in high risk infarct patients treated with primary angioplasty. METHODS High risk infarct patients referred from other centres for primary PTCA were randomized to treatment with or without an intra-aortic balloon pump. The primary end-point consisted of the combination of death, non-fatal reinfar...

Role of IABP in OPCAB - a vettath’s modification

Background In off-pump coronary artery bypass (OPCAB) surgery, the most critical complication is hemodynamic deterioration, which can occur during displacement of the heart to expose the target vessels. Pre-operative intra-aortic balloon pump (IABP) therapy has shown to improve cardiac performance and facilitates access to the target coronary artery while maintaining hemodynamic stability, espe...
