1 Quick but effective surgery for functional mitral regurgitation secondary to aortic valve disease 
Masashi Komeda, MD, PhD  The Journal of Thoracic and Cardiovascular Surgery  Volume 153, Issue 2, Pages (February 2017) DOI: /j.jtcvs Copyright © 2016 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 Modified relocation of PMs. Two papillary heads were connected by the PTFE suture in each PM, and the suture was externalized via subaortic curtain. The illustration of the posterior PM heads shows how to place a stitch to the 2 heads to connect them. PM, Papillary muscle; AH, anterior head; PH, posterior head; PTFE, polytetrafluoroethylene.

3 Figure 2 Echocardiography of a representative patient. A 64-year-old woman underwent the Bentall procedures and PHO relocation of the PMs via an aortic orifice. One year after the surgery, leaflets tethering, functional MR, and LV dilatation/sphericalization disappeared. Note that the patient did not receive mitral annuloplasty or left atriotomy. White triangular markers show artificial chordae for relocation. LV, Left ventricle; AL, anterior leaflet; PL, posterior leaflet; MA, mitral annulus; LA, left atrium; AC, artificial chordae.

5 Video 1 AR, Aortic regurgitation; Dd, diastolic diameter; DOE, dyspnea on effort; EF, ejection fraction; FMR, functional mitral regurgitation; LVA, left ventricular aneurysm; MAP, mitral annuloplasty; MR, mitral regurgitation; NCC, noncoronary cusp; NYHA, New York Heart Association; PHO, papillary heads optimization; PM, papillary muscle; PTFE, polytetrafluoroethylene; RCC, right coronary cusp; SVR, surgical ventricular restoration; TR, tricuspid regurgitation.
