  • Mitral Annulus

    Figure 2: Surgical anatomy of the mitral annulus with important surrounding structures.*The mitral valve is an atrio-ventricular valve, separating the left atrial chamber from the left ventricle. The mitral annulus constitutes the anatomical junction between the ventricle and the left atrium, and serves an insertion site for the leaflet tissue. It is often divided segmentally according to the site...

  • Chordae Tendinae

    Figure 1: Subvalvular apparatus of the mitral valve (Chordae tendinae and papillary muscles).*The chordae tendinae are the chord like structures connecting leaflets to the papillary muscle.The chordae tendinae are primarily responsible for the end-systolic position of the anterior and posterior leaflets. Arising from the papillary muscles, they are classified according to their site of insertion b...

  • Papillary Muscles and the Left Ventricle

    Subvalvular apparatus of the mitral valve (Chordae tendinae and papillary muscles).*Because the annulus resides in the left atrio-ventricular groove, and the chordae tendinae are connected to the ventricle via the papillary muscles, mitral valve function is integrally related to the ventricle. There are two papillary muscles arising from the area between the apical and middle thirds of the left v...

  • How Mitral Valve Heart Surgery Patients Can Get the Best Results

    Choosing the right surgeon to fix a leaky mitral valve - which can cause blood to flow backwards into the lungs and often leads to shortness of breath and chest pain is a critical decision.

    When patients have mitral valve disease, the small flaps that open and close to let oxygen-rich blood flow through the heart do not work as they should. Choosing the right surgeon to fix a leaky mitral valve - which can cause blood to flow backwards into the lungs and often leads to sho...

  • Assessment of longitudinal myocardial mechanics in patients with degenerative mitral valve regurgitation predicts postoperative worsening of left ventricular systolic function.

    Dimosthenis Pandis, MD, Partho P. Sengupta, MD, Javier Castillo, MD, Guiseppe Caracciolo, MD, PhD, Gregory W. Fischer, MD, Jagat Narula, MD, PhD, Anelechi C. Anyanwu, MD, and David H. Adams, MD

    The optimal timing of mitral valve repair (MVr) in patients with chronic severe degenerative mitral regurgitation (MR) remains controversial and is broadly based on either measurable loss of systolic function, as determined by left ventricular (LV) ejection fraction (LVEF) and/or LV cha...
