METHOD OF REDUCING MICROVASCULAR OBSTRUCTIONS BY PROVIDING VENTRICULAR SUPPORT
20260061182 · 2026-03-05 · ·

The disclosed technology relates to methods of preventing or limiting effects of heart failure in a human patient that has sustained acute myocardial infarction. The method includes determining that the patient is exhibiting acute myocardial infarction, inserting a transvalvular pump at least partially into a heart of the patient, and operating the transvalvular pump to cause blood to flow at a rate of at least 2.5 L/min for at least a support period. The method further includes performing a reperfusion of the patient's heart to restore blood flow to the heart after at least the support period has ended and reducing the amount of tissue actually comprising microvascular obstruction (MVO) of tissue that is at risk of MVO by approximately 20%.
