[Early Postoperative Hemodynamics of Mitral Valvuloplasty Using Colvin-Galloway Future Band].

ABSTRACT

The Colvin-Galloway( CG) Future annuloplasty band is a new semirigid partial band, which was introduced in 2012 in Japan. A total of 60 consecutive patients who underwent mitral valve repair with the CG Future Band were assessed by echocardiography in terms of residual mitral regurgitation and diastolic mitral function postoperatively. Intraoperative 3-dimensional echocardiography beautifully demonstrated the physiological change of the aortic curtain during the cardiac cycle. 30 mm was used in 18 patients, 32 mm in 17, 28 mm in 15, 34 mm in 5, 36 mm in 2, and 26 mm in 2. There were 2 patients with mild residual mitral regurgitation and 58 patients with less than mild. The mean gradient of diastolic mitral pressure gradient was 2.8±1.3 mmHg. Early results of mitral valve repair with a CG Future Band were acceptable in terms of residual mitral regurgitation and diastolic mitral function after repair.
