An intelligent “pump” helps the heart in high-risk angioplasty

by admin

Do you know a “whisk”? Inside the heart, it obviously does not serve to mix the blood. But, as a real “pump” it helps to push it into the aorta, and therefore throughout the body, while the patient is under “stress” because the cardiologist is releasing a coronary artery from a plaque with a “balloon” which occludes it. Thanks to technology, in addition to favoring the thrust of the liquid from the heart to the body, today it is also possible to constantly monitor what happens in the left ventricle, understand if it can withstand the effort, evaluate the pressure with which, also thanks to the “whisk” , pushes the blood. With this system, now also equipped with optical fibers, it is therefore possible to carry out the revascularization treatment even in subjects at very high risk because they have particularly dangerous diseases. And above all it is possible to monitor moment by moment what happens in the continuous whirlwind of blood inside the left ventricle. The figure emerges from a virtual conference organized by the De Gasperis Foundation. “Until now Chip patients (higher-risk and clinically indicated patients), that is people at high risk for comorbidities, left ventricular dysfunction linked to severe decompensation, serious heart valve disease or even severe coronary artery disease, could not be treated for the high risk of mortality during the procedure – explains the director of Cardiology 1- Hemodynamics, Cardiological Intensive Care Unit of the Cardiothoracovascular Department “A. De Gasperis” of the Niguarda Hospital in Milan Fabrizio Oliva, The reason is simple: the persistence of a dysfunction of the cardiac pump exposes the patient to a greater risk of re-hospitalization and distant mortality but also to a worse quality of life “.

In this sense, technology can profoundly change history. In fact, when a scheduled angioplasty is planned, the specialist can non-invasively insert the device into the heart of the high-risk patient, which is practically positioned in the left ventricle. “At that point two fundamental functions can be obtained: the first is to control the pressure values, made even more effective by the availability of optical fibers, the second is to favor the pump function of a ventricle which, for the reasons mentioned above, works bad – resumes Oliva. All this allows an adequate perfusion of the vital organs, from the heart itself to the brain and kidneys. Above all, the device can be “left” to control the situation in the hours following the revascularization intervention, even for a day or more “. Thanks to technology, therefore, important prospects are opening up for those who, only some time ago, could not be initiated for angioplasty treatment due to their health conditions. “Today the treatment is possible thanks to the improvement of techniques and devices such as the temporary circulation support system, an intracardiac microaxial pump that supports the left ventricle, which can be easily positioned percutaneously: with the availability of a system equipped with fibers optics, it is possible to obtain an even more precise monitoring of the pressure signals and therefore a better clinical management of the high-risk patient – concludes Jacopo Oreglia, Head of Hemodynamics of the “A. De Gasperis ”, supported by the De Gasperis foundation”.
