Continuous aortic flow augmentation: not enough MOMENTUM.
The study by Greenberg et al1 published in this issue of Circulation details the results of the randomized clinical trial known as the Multicenter trial of the Orqis Medical Cancion system for the ENhanced Treatment of heart failure Unresponsive to Medical therapy (MOMENTUM). The Orqis device is a new entry into the field of temporary mechanical circulatory support for severe heart failure. The...
متن کاملAugmentation of Coronary Blood Flow by Intra - aortic Balloon Pumping in Patients After Coronary
Background. Controversy exists regarding the ability of intra-aortic balloon pumping to increase coronary blood flow in patients with obstructive coronary artery disease. To assess the effects of intra-aortic balloon pumping on coronary hemodynamics, we measured coronary blood flow velocity with a 0.018-in. Doppler-tipped angioplasty guide wire in 15 patients who received an intra-aortic balloo...

متن کاملAugmentation of regional coronary blood flow by intra-aortic balloon counterpulsation in patients with unstable angina.
Intra-aortic balloon counterpulsation is capable of reducing afterload in patients with unstable angina. Whether it is also capable of augmenting coronary blood flow to poststenotic myocardium is controversial. We studied seven patients receiving maximal drug therapy and requiring balloon pumping for unstable angina as balloon volume and assist ratio were altered. All patients had greater than ...
متن کاملImages in cardiovascular medicine. Augmentation of coronary blood flow with intra-aortic balloon pump counter-pulsation.
Intra-Aortic Balloon Pump Counter-Pulsation To the Editor: The imaging of coronary flow1 during intra-aortic balloon pumping is important and might be used to adjust the timing of balloon deflation better. In the series of figures shown by Ryan and Foster,1 with intra-aortic balloon pumping assisting every second beat, there was no consistent reduction of systolic pressure in the intervening un...
