The mitral valve (MV) separates the left atrium (LA) and left ventricle (LV). It's a bileaflet valve composed of an anterior and posterior leaflet, each with three "scallops" designated A1, A2, A3, P1, P2, and P3. The A3-P3 interface tapers…

What Is An Impella?

Impella® is a percutaneous axial heart pump placed retrograde across the aortic valve into the left ventricle (LV) utilizing fluoroscopy +/- echocardiography. Its indications include high risk percutaneous coronary intervention (PCI,…

EKG Axis Deviation

The normal cardiac electrical conduction pathway propagates from the right atrium down towards the left ventricle. In other words, the cardiac conduction axis is normally downward and leftward. Bipolar limb lead I (points to the left) and…
