OBJECTIVES: Following mitral valve repair for Barlow's disease, recurrent mitral regurgitation (MR) is believed to occur frequently and is mainly attributed to disease progression. METHODS: Between January 2000 and December 2015, 180 patients (40% women, mean age 58.7 ± 13.5 years) with Barlow's disease underwent mitral valve repair. To provide a longitudinal assessment of mitral valve repair durability, a multistate model for interval-censored observations (4 states: 1, Grade 0/1+ MR; 2, Grade 2+ MR; 3, Grade 3+/4+ MR; 4, reintervention/death) was developed...

We report the case of a 38-year-old woman who was admitted for acute cerebral infarction linked to a cardiac calcified amorphous tumor (CAT) and related mitral annular calcification (MAC). The cardiac mass was removed, and mitral valve replacement surgery was performed. Pathological examination revealed an amorphous accumulation of degenerating material within both lesions, indicating that build-up of calcium along the mitral annulus and subsequent rupture of the fibrotic tissue may be involved in the initiation and progression of CAT...

PURPOSE OF REVIEW: Despite the proven superiority of mitral repair over replacement for degenerative mitral disease, mitral valve replacement remains common. Guidelines now recommend referral of patients, particularly those whom are asymptomatic, to valve centers of excellence, although criteria that define such centers remain to be established. The purpose of this review is to define the structure of a mitral center of excellence and to review current clinical outcomes which are possible in such a center...

Objectives: Transcatheter aortic valve implantation (TAVI) and transcatheter mitral valve repair (TMVR) are increasingly used for managing patients with valvular heart disease to whom surgery presents a high-risk. As these are costly procedures, a systematic review of studies concerned with their economic assessment was undertaken. Methods: The search was performed in PubMed and the Cochrane Library and followed recommended methodological steps. Studies were screened and their data were retrieved and were synthesized using a narrative approach...

BACKGROUND: Isoflurane, a common anesthetic for cardiac surgery, reduced myocardial contractility in many experimental studies, few studies have determined isoflurane's direct impact on the left ventricular (LV) contractile function during cardiac surgery. We determined whether isoflurane dose-dependently reduces the peak systolic velocity of the lateral mitral annulus in tissue Doppler imaging (S') in patients undergoing cardiac surgery. METHODS: During isoflurane-supplemented remifentanil-based anesthesia for patients undergoing cardiac surgery with preoperative LV ejection fraction greater than 50% (n = 20), we analyzed the changes of S' at each isoflurane dose increment (1...

The outcome in functional mitral regurgitation after aortic valve replacement is unclear. A frail 82-year-old woman with severe aortic valve regurgitation and mild to moderate functional mitral valve regurgitation (NYHA functional class III) was referred to our clinic. In consideration of her frail condition, aortic valve replacement without mitral surgery was performed. She had hemodynamic instability and difficulty to wean off cardiopulmonary bypass caused by severe functional mitral valve regurgitation with left ventricular dilatation...

Background: The radiofrequency (RF) maze procedure can effectively restore sinus rhythm in most patients with persistent atrial fibrillation (AF) and mitral disease. However, long-term results and predictors for late AF recurrence are still under investigation. Methods: From December 1995 to November 2011, 207 consecutive patients with persistent AF and mitral disease underwent RF maze procedure and concomitant mitral surgery. The mean age was 54±12.4 year-old...

Transcatheter heart valve replacement technology was introduced as alternative to surgery for the growing high-risk profile population. Developed first, aortic valve replacement (TAVR) became a standard of care for patients with severe aortic stenosis at high operative risk, with a potential future use also for low-risk subjects. In the last decade, a multitude of transcatheter mitral valve replacement (TMVR) devices have been developed for the treatment of severe mitral regurgitation, with encouraging results coming from first-in-man and feasibility studies...

Parachute mitral valve (PMV) is a congenital heart anomaly which consists of a unifocal attachment of the mitral valve chordae into a single or dominant papillary muscle. This morphological anomaly determines the impairment of mitral leaflet motion, resulting in different grades of mitral stenosis. Due to its frequent association with other congenital cardiac defects requiring surgical correction, the therapy of a relevant stenotic PMV is usually represented by surgical commissurotomy. Herein is reported the case of a PMV treated by surgery in infancy, which showed a severe restenosis after 34 years and was successfully treated by percutaneous valvuloplasty with the additional creation of a restrictive atrial communication...

Background: Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. Material and Methods: A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups)...

Caseous calcification of the mitral annulus (CCMA) is a rare echocardiographic finding. It is commonly misdiagnosed as an abscess, tumor or infective vegetation on the mitral valve. Since it is a benign process, differentiating it from malignant intra-cardiac mass is primordial to avoid unnecessary surgery. Various imaging modalities can be complimentary for definitive diagnosis. We present a case of CCMA in a 71-year-old female patient. Her medical history revealed hypertension, diabetes mellitus, hyperlipidaemia and coronary artery disease...

AIMS: Mitral valve interstitial cells (MVIC) play an important role in the pathogenesis of degenerative mitral regurgitation (MR) due to mitral valve prolapse (MVP). Numerous clinical studies have observed serotonin (5HT) dysregulation in cardiac valvulopathies; however, the impact of 5HT-mediated signaling on MVIC activation and leaflet remodeling in MVP have been investigated to a limited extent. Here we test the hypothesis that 5HT receptors (5HTRs) signaling contributes to MVP pathophysiology...
