Here are the top 10 takeaways from the late-breaking studies on cardiovascular technologies presented at the 2021 American College of Cardiology (ACC...
Cath Lab Navigation Aids
This channel includes news and new technology innovations for navigation aids to help guide interventional procedures. These include advanced imaging, fusion imaging, rotational angiograpy, fluoro overlay images, robotic systems, and 3D printing and holograms for use in the interventional lab or cath lab.
Some of the top technology news from ACC 2021. Top left, the LAAOS III trial showed benefit when surgeons seal off the LAA during other open heart procedures. Bottom left, the ReCor Paradise renal denervation system helped lower blood pressure in patients who did not respond to medication. Top right, for patients with both heart failure and AFib it makes no difference if therapy is focused on controlling the heart rhythm or heart rate. Bottom right, the FLOWER-MI trial found no benefit to FFR-guided PCI in STEMI with multi-vessel disease.
There is a trend in interventional cardiology that is now being called “renalism,” where patients with poor renal function are being excluded from interventional procedures because they are automatically considered too high risk. However, some hospitals are also creating cardio-renal care teams so these patients can be cared for by a team of experts rather than interventional cardiologists going it alone.
Explaining the Emory TMVR angle. Discordance between mitral annular centerline (yellow lines) and valve orientation imposed by guidewire position within the LV apex (red dashed lines). (B) Valve intrinsic angle (α) is determined by external skirt height. (C) When annular-apical “Emory” angle (red curves) exceeds α (blue curve), annular skirt apposition is not possible, causing PVL (red arrows). (D) The valve is oriented perpendicular to the annual plane using an exteriorized apical guidewire (solid yellow line). Image courtesy of Kendra Grubb, M.D.
Abbott recently announced its new interventional imaging platform powered by Ultreon 1.0 Software, has gained European CE marked. This first-of-its-kind imaging software merges optical coherence tomography (OCT) intravascular imaging with the power of artificial intelligence (AI) for enhanced visualization. The new Ultreon Software can automatically detect the severity of calcium-based blockages and measure vessel diameter to enhance the precision of physicians’ decision-making during coronary stenting procedures.
SpectraWave is developing a a new intravascular imaging system that combines two currently available modalities. This likely includes optical coherence tomography (OCT), left, which can define structures within the vessel and vessel wall. Near infrared spectroscopy (NIRS), right, enables a spectral chemical analysis of the vessel walls to show areas of high lipid content, and specifically can identify lipid-core plaques that are associated with heart attack-causing plaque ruptures.
