A woman aged 36 years G2P1 presented at our outpatient clinic with symptoms of discomfort, dyspnoea and fever at a gestational age of 17 weeks. She was subsequently diagnosed with severe endocarditis with a large vegetation on the mitral valve. She underwent open chest mitral valve surgery while on cardiopulmonary bypass (CPB) within a few days. Such surgical intervention is not only associated with increased maternal risks, but also with severe fetal morbidity and mortality. In such patients, certain perioperative measures can diminish these risks...

BACKGROUND: Prominent mitral valve (MV) annular dilatation with only modest left ventricular (LV) dilatation in patients with MV prolapse (MVP) suggests predominant dilatation in adjacent basal LV, which may augment regional wall tension and attenuate contraction by Laplace's law. We hypothesized that MV annular dilatation in patients with MVP is associated with the basal predominance of LV dilatation and attenuated contraction, which can be altered by surgical MV plasty with annulus reduction...

We perform minimally invasive mitral valve plasty under totally endoscopic view. Skin incisions are composed of a 3 to 5 cm of main wound along the right 4th intercostal space, 1 trocar port in the 3rd intercostal space, and a camera port in the 5th intercostal space. Matal rib spreader is not used. A 3-dimensional endoscope was recently introduced. Forceps controlled by the left hand are inserted through the independent trocar port in the 3rd intercostal space. Left atrial retractor, aortic clamp, and all the cannulae are inserted through the main incision...

We performed coronary artery grafting, mitral valve plasty, and tricuspid plasty in a 75-year-old man who had double-vessel coronary disease and moderate mitral and tricuspid insufficiency. Preoperative transthoracic echocardiography revealed an ejection fraction of 34% and dyssynchronous wall motion of the septum and free wall. We placed pacing leads on the right ventricular outlet and posterior left ventricular wall for cardiac resynchronization therapy. The dyssynchrony disappeared postoperatively and the New York Heart Association functional class improved from IV to I...

The single-suture neochorda-folding plasty technique is a modification of existing mitral valve repair techniques. In the authors' experience, its simplicity, reliability, and versatility make it a useful technique for mitral valve repair, especially when a minimally invasive approach is used.

Early surgical intervention is required for sudden onset, severe mitral regurgitation (MR) due to chordal rupture in infants with normal development younger than 1 year. The condition has been recognized as idiopathic. However, the surgical options in children are limited because of their size and somatic growth. We sought to examine the efficacy of mitral valve plasty by artificial chordal reconstruction for these infants in mid-to-long term. From August 2005 through June 2012, 8 consecutive patients aged 1-7 months underwent mitral valve plasty by chordal reconstruction using expanded polytetrafluoroethylene sutures for MR, owing to leaflet prolapse...

We report the usefulness of retrograde cardioprotective(RC)-beating test as a method to evaluate mitral valve plasty (MVP). MVP has been established as an effective procedure for mitral regurgitation, but nevertheless, a problem remains as to how to reduce postoperative residual regurgitation. In order to solve this problem, it is crucial to image the 3 dimensional structures of the mitral valve and its systolic condition. However, it is quite difficult especially in cases of situs inversus totalis (SIT). RC-beating test gives a clear view of the mitral valve and precisely evaluates the performance of MVP, which is particulary helpful in SIT patients...

Fifteen consecutive prosthetic valve endocarditis (PVE) patients were operated from March 2009 to September 2014. The average age of patients was 68 years ( range 49 to 82) and 7 patients were male. The interval between initial surgery and reoperation was 62.4 months(range 2.6 to 340.9). Seven of these cases(47%) developed PVE within the 1st year after surgery were defined as early PVE. All microorganisms isolated from blood cultures in early PVE were Staphylococcus species. Generally, the infective prosthetic valve was removed 1st, then all infective tissues were excised from the periannular cavity...

Between 2003 and 2014, at Jichi Medical University Hospital, 11 patients with prosthetic valve endocarditis (PVE) underwent re-operation. There was 1 in-hospital death and 2 late deaths. The cause of death was cirrhosis, heart failure and sepsis, respectively. Emergency surgery, previous double valve replacement (DVR) and Staphylococcus infection were common risk factors for all 3 cases. Two cases of patients that survived who underwent mitral valve replacement (MVR) and DVR for PVE after DVR were treated with multiple antibiotic courses for bacteremia associated with hemodialysis and colon cancer...

OBJECTIVES: The purpose of this retrospective study was to analyse the pathogenesis and the treatment strategies of hypertrophic obstructive cardiomyopathy (HOCM) with the concomitant mitral valve abnormalities. METHODS: Between October 1996 and December 2009, 76 patients with the HOCM underwent the ventricular septal myotomy-myectomy in Fuwai hospital. There were 51 males and 25 females aged between 6 and 68 years (mean: 37.18 ± 15.85 years) old. All the patients had left ventricular outflow tract (LVOT) obstruction with a resting or physically provoked gradient of ≥50 mmHg and the systolic anterior movement (SAM) of the mitral leaflets, and 64 patients had mitral regurgitation (MR)...

Prosthetic valve replacement has mainly been performed on patients with mitral regurgitation. In such cases, prosthetic valve related complications, such as thromboembolism, bleeding, prosthetic valve infection, and structural valve deterioration, are unavoidable. With valve plasty, however, not only can such complications be avoided, but patients can also have as good a quality of life as healthy people without medications. Although mitral valve plasty requires complicated techniques like chordal reconstruction and has problems of residue, recurrence, and progression of regurgitation, patients with mitral valve prolapse are considered to be good candidates for this procedure...

OBJECTIVE: The Japanese Circulation Society recommends discontinuation of antiplatelet therapy 7-14 days before major surgery. However, reports on the relationship between the timing of clopidogrel discontinuation and the risk of postoperative bleeding in Japanese subjects are lacking. We assessed the optimal timing of clopidogrel discontinuation before elective surgery using the VerifyNow® P2Y12 assay. In addition, the relationship between preoperative platelet function and risk of postoperative bleeding was evaluated...
