AIMS: In patients with ischaemic mitral regurgitation (MR), the impact of mitral valve surgery with concomitant coronary artery bypass grafting (CABG) on post-operative survival and left ventricular (LV) reverse remodelling remains unknown. Therefore, we investigated these outcomes following restrictive mitral annuloplasty (RMA) with and without CABG in those patients. METHODS AND RESULTS: This study included 309 patients with chronic MR and ischaemic cardiomyopathy for whom concomitant CABG was...

Abstract Re-expansion pulmonary edema (RPE) is a serious complication of minimally invasive cardiac surgery (MICS) through the right minithoracotomy. As re-expansion mechanical injury and ischemia reperfusion injury to the collapsed lung are possible mechanisms, we introduced a preventive protocol that consists of intermittent ventilation of the right lung, restoration of bilateral ventilation, administration of mannitol before unclamping the aorta, and institution of mild hypothermia. Among 469...

: We evaluated impact of a small-sized Mosaic porcine bioprosthesis on hemodynamic performance and outcomes in patients with aortic stenosis (AS) and low left ventricular ejection fraction (LVEF) in a Japan multicenter cohort. Of 1,202 patients enrolled, 105 (8.7%) who had LVEF < 50% and AS underwent aortic valve replacement (AVR). Fifty-two patients received Mosaic porcine bioprosthesis ≤ 21 mm (S-AVR), and 53 received a bioprosthesis ≥ 23 mm (L-AVR). The median follow-up period was 3.1 [1.2, 5...

Abstract Objective The aim of this study is to evaluate mitral valve hemodynamics after mitral valve repair for degenerative disease, and seek the impact of type/size of annuloplasty prosthesis on resting cardiac hemodynamics. Methods Between October 2012 and June 2019, 301 patients underwent isolated mitral valve repair for degenerative disease were enrolled. Correlation between postoperative mitral hemodynamics and type/size of annuloplasty prosthesis was evaluated. Results There were signific...

BACKGROUND: Carpentier's techniques for degenerative posterior mitral leaflet (PML) prolapse have been established with excellent long-term results reported. However, residual mitral regurgitation( MR) occasionally occurs even after a straightforward repair, though the involved mechanisms are not fully understood. We sought to identify specific preoperative echocardiographic findings associated with residual MR after a PML repair. METHODS AND RESULTS: We retrospectively studied 117 consecutive p...
Here, we demonstrate the details of annular decalcification using an ultrasonic aspirator in minimally invasive aortic valve replacement for aortic stenosis. In our debridement procedure, the aortic valve leaflets are excised with enough valve tissue left, not just at the annulus. The invisible annulus is exposed by traction of the remnant valve tissue, and the annular calcifications are scraped off using an ultrasonic aspirator. After an annular decalcification, the remnant valve tissue was com...
