commissurotomy

 [kom″ĭ-sher-ot´ah-me]
surgical incision or digital disruption of the components of a commissure to increase the size of the opening.
mitral commissurotomy the breaking apart of the adherent leaflets (commissure) of the mitral valve, a formerly common treatment for mitral stenosis.

com·mis·sur·ot·o·my

1. Surgical division of any commissure, fibrous band, or ring via an incision or disruption, for example, balloon inflation.
2. Synonym(s): midline myelotomy

commissurotomy

/com·mis·sur·ot·o·my/ (-ot´ah-me) surgical incision or digital disruption of the components of a commissure to increase the size of the orifice; commonly done to separate adherent, thickened leaflets of a stenotic mitral valve.

commissurotomy

(kŏm′ə-sho͝o-rŏt′ə-mē)
n. pl. commissuroto·mies
Surgical incision of a commissure in the body, as one made in the heart to relieve constriction of the mitral valve or one made in the brain to treat seizure disorders.

commissurotomy

[kom′ishoo͡rot′əmē]
Etymology: L, commissura, a connection; Gk, temnein, to cut
the surgical division of a fibrous band or ring connecting corresponding parts of a body structure. A commissurotomy is commonly performed to separate the thickened, adherent leaves of a stenosed mitral valve.

commissurotomy

Surgery The surgical splitting of a commissure–eg in the brain or cusps of heart valves. See Percutaneous transvenous mitral commissurotomy.

(kom'i-shŭr-ot'ŏ-mē)
1. Surgical division of any commissure, fibrous band, or ring using surgery or a balloon catheter technique.
2. Synonym(s): midline myelotomy.

Percutaneous mitral balloon valvuloplasty (PMBV) has been developed as an alternative modality to surgical closed commissurotomy for mitral stenosis (MS)(1), and excellent hemodynamic improvement with favorable outcome has been reported by many investigators (2-11).
