Chordal cutting combined with ring annuloplasty and coronary bypass successfully eliminated severe functional mitral regurgitation and improved leaflet mobility in a patient with a severely restricted anterior leaflet.
Chordal cutting plus annuloplasty may relieve anterior leaflet tethering in functional MR; leaves open need for prospective outcome data.
Functional mitral regurgitation (MR) is usually caused by cardiomyopathy. Herein, we present chordal cutting and ring annuloplasty due to severely restricted anterior leaflet. Seventy-seven years old, male patient suffering shortness of breath had the diagnosis of severe mitral regurgitation and coronary artery disease. Preoperative echocardiography showed reduced ejection fraction and severe central jet due to tethering of secondary chordae. Restricted chordae were resected by transverse aortotomy, saphenous graft bypass was done, and semi-rigid ring was implanted. Postoperative echocardiography showed no residual regurgitation, excellent mobility of anterior leaflet. Chordal cutting seems to be an effective technique to treat functional MR caused by the restriction of anterior leaflet

Ertugay et al. (2022) conducted a case report in Severe functional mitral regurgitation (n=1). Chordal cutting and ring annuloplasty was evaluated on Residual mitral regurgitation and anterior leaflet mobility. Chordal cutting combined with ring annuloplasty successfully eliminated residual regurgitation and restored excellent mobility of the anterior leaflet in a patient with severe functional mitral regurgitation.
