Giant Thrombus Formation Immediately After Mitral Valvuloplasty.
We report the case of a 65-year-old woman with severe mitral regurgitation (MR) and AF in whom a giant thrombus formed almost immediately after mitral and tricuspid valvuloplasty and concurrent LAA resection. No atrial thrombus or spontaneous echo contrast (SEC) was detected by TEE before the surgery. However, a giant intramural thrombus was detected in the left atrium 7 days after surgery. It was thought that the atrial dysfunction as well as the change in morphology of the left atrium resulting from the severe MR complicated by AF and congestive heart failure produced a thrombotic substrate. This case suggests that caref...

Transcatheter treatment of severe tricuspid regurgitation with the MitraClip system
Conclusions Transcatheter tricuspid valve repair by use of interventional edge-to-edge repair with the MitraClip system was feasible, and safe in three consecutive patients. Reduction of tricuspid insufficiency associates with relief of clinical symptoms for right heart failure. This strategy seems a promising treatment option for patients at prohibitive surgical risk.

Repeated Aortic Balloon Valvuloplasty in Elderly Patients With Aortic Stenosis Who Are Not Candidates for Definitive Treatment.
CONCLUSION: BAV is associated with poor long-term clinical outcome. However, when no other therapeutic options are feasible, a strategy of repeated palliative BAV appears to be safe and is potentially associated with improved clinical outcomes. PMID: 26378413 [PubMed - in process]

Surgical ventricular restoration plus mitral valve repair in patients with ischaemic heart failure: risk factors for early and mid-term outcomes ADULT CARDIAC
CONCLUSIONS MV repair combined with SVR is a complex and challenging procedure that can be performed with acceptable early and mid-term results. Interestingly, angina features predict both early and late outcome, with unstable angina at the time of surgery being a predictor of poor early outcome and the absence of angina at surgery, a predictor of favourable outcome at mid-term follow-up.

Mitral valve repair using robotic technology: Safe, effective, and durable
The most recent American College of Cardiology/American Heart Association heart valve guidelines recommend that prompt surgical correction of severe degenerative mitral valve regurgitation, ideally mitral valve repair, should be performed to decrease the risks of long-term mortality and heart failure risks associated with this condition. Mitral valve repair performed using a minimally invasive robotic approach can now be successfully carried out in nearly all cases of degenerative disease with very low risks of stroke or death.

Validated Risk Score for Predicting 6-Month Mortality in Infective Endocarditis Valvular Heart Disease
Conclusions Six-month mortality after IE is 25% and is predicted by host factors, IE characteristics, and IE complications. Surgery during the index hospitalization is associated with lower mortality but is performed less frequently in the highest risk patients. A simplified risk model may be used to identify specific risk subgroups in IE.

An approach to a patient with infective endocarditis.
Authors: Hitzeroth J, Beckett N, Ntuli P Abstract Although infective endocarditis (IE) is relatively uncommon, it remains an important clinical entity with a high in-hospital and 1-year mortality. It is most commonly caused by viridans streptococci. Staphylococcus aureus is responsible for a malignant course of IE and often requires early surgery to eradicate. Other rarer causes are various bacilli, including the HACEK (Haemophilus, Actinobacillus,Cardiobacterium, Eikenella and Kingella spp.) group of organisms and fungi. The clinical presentation varies. Patients may present with a nonspecific illness, valve dysfu...

Treatment of Chronic Functional Mitral Valve Regurgitation With a Percutaneous Annuloplasty System
ConclusionsPercutaneous direct annuloplasty is feasible and safe in high-risk FMR patients. This treatment initiates LV reverse remodeling, and provides clinical improvement during 6 months after treatment. (Mitralign Percutaneous Annuloplasty First in Man Study; NCT01852149).

Taking Risk: Early Results From Teaching Hospitals’ Participation in the Center for Medicare and Medicaid Innovation Bundled Payments for Care Improvement Initiative
The authors describe observations from the 27 teaching hospitals constituting the Association of American Medical Colleges (AAMC) cohort in the Center for Medicare and Medicaid Innovation (CMMI) Bundled Payments for Care Improvement (BPCI) initiative. CMMI introduced BPCI in August 2011 and selected the first set of participants in January 2013. BPCI participants enter into Medicare payment arrangements for episodes of care for which they take financial risk. The first round of participants entered risk agreements on October 1, 2013 and January 1, 2014. In April 2014, CMMI selected additional participants who started takin...

Atrial Fibrillation Patients Treated With Long-Term Warfarin Anticoagulation Have Higher Rates of All Dementia Types Compared With Patients Receiving Long-Term Warfarin for Other Indications Cardiovascular Surgery
Conclusions The presence of AF significantly increases risk of dementia, including Alzheimer's disease, compared with matched patients receiving warfarin anticoagulation for other reasons. Quality of anticoagulation management remains an important risk factor for dementia in all patients.

Study: TAVR safer than surgery in low-risk heart failure patients
Transcatheter aortic valve replacement procedures with self-expanding systems resulted in higher survival rates for patients at lower risk for surgery when compared to surgical aortic valve replacement procedures, according to a study released this month. Results from the study, which compared Medtronic‘s (NYSE:MDT) self-expanding CoreValve TAVR system, were published in JAMA Cardiology this month. The retrospective analysis compared patients from the CoreValve U.S. pivotal high-risk trial of patients with STS PROM scores of 7% or less who either underwent TAVR procedures or surgery, with a median STS Prom score of...

The Challenge of Timing Surgery in Degenerative Mitral Regurgitation Is B-Type Natriuretic Peptide the Solution? ∗
Degenerative mitral regurgitation (MR) with prolapse or flail of mitral leaflets has become the most frequent cause of severe primary MR in Europe and North America (1,2). In its chronic stage, even severe MR is tolerated very well for a surprisingly long time, and patients may remain asymptomatic for years. During this compensated stage of disease, pre-load, afterload, and both contractility and ejection fraction of the left ventricle (LV) remain normal, and the total stroke volume is increased as a result of the compensatory enlargement of the end-diastolic LV volume, which is enabled by an adaptive process of the LV myo...
