Komoda Takeshi - - 2009
When mitral annuloplasty is performed in small children, room for annular growth should be allowed. However, it has not been reported how the valve develops after mitral annuloplasty of the entire posterior annulus. We report a case showing traces of annular growth at redo surgery. A female patient suffering from ...

BACKGROUND: Management of severe ischemic mitral regurgitation remains difficult with disappointing early and intermediate-term surgical results of valve repair. METHODS AND RESULTS: Forty-four patients with severe (4+) Carpentier type IIIb ischemic mitral regurgitation underwent mitral valve repair, with or without surgical revascularization, by posterior leaflet extension with a patch of ...

Closure of a mitral valve (MV) cleft, small left-sided cardiac structures, and ventricular imbalance all may contribute to mitral stenosis (MS) after repair of atrioventricular canal (AVC) defects. MV replacement is the traditional therapy but carries high risk in young children. The utility of balloon mitral valvuloplasty (BMV) in postoperative ...
Onorati Francesco - - 2009
BACKGROUND: Despite restrictive mitral annuloplasty (RMA) being considered effective for chronic ischaemic mitral regurgitation (CIMR), few data exist on mid-term echocardiographic results with different prosthetic rings. Therefore, comparative echocardiographic analysis has been performed. METHODS: Sixty-four consecutive coronary artery bypass graft surgery (CABG) + RMA (downsizing by two-ring sizes; median size: ...

BACKGROUND: Unexpected postoperative left ventricular (LV) dysfunction after valve repair for mitral regurgitation (MR) occurs in some patients with normal preoperative LV function. Identification of factors that predispose to such LV dysfunction would enhance our understanding of the indications and outcomes of surgery. METHODS: We retrospectively analyzed pre- and postoperative ...

Cooray Shamil D - - 2009
BACKGROUND AND AIM OF THE STUDY: Annuloplasty sizing with standard valve sizers may be imprecise and difficult in minimally invasive procedures. It is hypothesized that a constant clinical conversion factor relates the echocardiographic aortic annulus diameter (AAD) and the intertrigonal distance (ITD) in patients with degenerative mitral regurgitation (MR). This ...
Sulcaj Laureta - - 2009
BACKGROUND: Repair of anterior leaflet prolapse is technically more challenging and this might influence outcomes as compared to the repair of posterior leaflet prolapse in patients undergoing surgical correction of mitral regurgitation. We investigated the association of anterior leaflet prolapse with minor residual mitral regurgitation (MR) in patients with mitral ...
Song Bong Gun - - 2009

BACKGROUND AND AIM OF THE STUDY: The initial application of repair to rheumatic mitral disease was fraught with unacceptable recurrence rates. For this reason, rheumatic valves primarily have been replaced in recent years. Early and late outcomes with replacement, however, have continued to be suboptimal, prompting a re-examination of repair. ...
