Mitral valve annuloplasty has been the gold standard for treatment of functional mitral valve regurgitation. However, annuloplasty for functional mitral regurgitation may cause augmented posterior leaflet tethering, which results in functional anterior prolapse. Herein we added papillary muscle heads focalization for such patients. All separated papillary muscle heads are sutured together, and the roots of chordae at each papillary muscle are unifocalized on both sides. Stitches are positioned at the same distances from corresponding leaflet edges to adjust the height of leaflet edges in each segment. This is a simple and effective technique to correct for functional anterior prolapse after annuloplasty.

A 53-year-old male individual with chronic severe mitral regurgitation presented with biventricular dysfunction, pulmonary hypertension, and atrial fibrillation. Echocardiography demonstrated a posterior leaflet prolapse with malcoaptation. Mitral valve repair and Maze procedure were performed, revealing absent chordae and direct connection from the anterolateral papillary muscle to the posterior leaflet, consistent with partial mitral arcade.

For adults, the standard procedure for mitral valve repair of Carpentier classification type II mitral regurgitation is reconstruction with artificial chordae. In children, placement of artificial chordae of precise length between the papillary muscle and prolapsed mitral leaflet in the restricted mitral subvalvular space is technically difficult. We successfully performed mitral valve repair in 3 pediatric patients using a modified fixed loop-in-loop technique.

A male in his seventies presented with lung cancer in the right lower lobe. The surgically resected specimen revealed a pleomorphic carcinoma featuring an adenocarcinoma component with lepidic, acinar, and papillary patterns, alongside a spindle cell component spreading along the pulmonary artery wall, resembling intimal sarcoma. The spindle tumor cells were positive for keratins, TTF-1, napsin A, and vimentin, but negative for p40, CK14, desmin, alpha-smooth muscle actin, CDK4, and MDM2.

Background: Secondary mitral regurgitation (SMR) is a condition affecting the left ventricle (LV) rather than the mitral valve (MV). If the MV remains structurally unchanged, enlargement of the LV or impairment of the papillary muscles can occur. Several mechanical interventions are available to dictate the resolution of MR.
