Stroke in Patients With Aortic Stenosis: The Simvastatin and Ezetimibe in Aortic Stenosis Study Clinical Sciences
Conclusions— In patients with aortic stenosis not prescribed oral anticoagulation, atrial fibrillation, AVR with concomitant coronary artery bypass grafting, and CHA2DS2-VASc score were the major predictors of stroke. Incident stroke was strongly associated with mortality. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00092677.

Intermediate-term rates of stroke following cardiac procedures: the Nationwide Readmissions Database (P4.305)
Conclusions:Using a large, nationally representative database of inpatient admissions from 2013, we found that 90-day stroke rates are higher after cardiac procedures compared to non-cardiac procedures and non-surgical admissions. However, these rates are likely lower than previously reported.Disclosure: Dr. Stein has nothing to disclose. Dr. Thaler has nothing to disclose. Dr. Liang has nothing to disclose.

FDA warns of high stroke, mortality risk with SynCardia TAH-t C2 controller
The FDA on Friday released a letter warning of a higher mortality risk and stroke rate than expected for patients receiving treatment from SynCardia Systems’ Temporary Total Artificial Heart Companion 2 Driver System. Data indicating the higher mortality and stroke rate came from a post-approval study conducted by the company itself, the FDA said. The study indicated that patients treated with the previous generation driver of the device, the Circulatory Support System Console, experienced a lower rate of stroke and mortality compared with the C2. The TAH-t system is designed to function as a bridge to a heart transplant...

Perioperative changes of the slope in the preload recruitable stroke work relationship by a single-beat technique after mitral valve surgery in functional mitral regurgitation with non-ischemic dilated cardiomyopathy
ConclusionsThe change of slope was dependent on surgical procedures. In functional mitral regurgitation, the slope may be a more sensitive parameter in reflecting the left ventricular contractile function than the left ventricular ejection fraction.

Perioperative risk of major non-cardiac surgery in patients with severe aortic stenosis: a reappraisal in contemporary practice
Conclusion Severe aortic stenosis is associated with increased risk of MACE. In contemporary practice, perioperative mortality of patients with SAS is lower than previously reported and the difference from controls did not reach statistical significance. Emergency surgery is the strongest predictor of post-operative death. These results have implications for perioperative risk assessment and management strategies in patients with SAS.

This year's top 10 advances in cardiovascular disease
Progress in the fight against heart disease and stroke came on many fronts during 2014, from novel drugs and procedures to improvements and newfound benefits from existing treatments. In the December 2014 Harvard Heart Letter, Editor in Chief Dr. Deepak L. Bhatt selected 10 of the most important advances. New drugs cut cholesterol levels by half. A new class of drugs, given by injection just once or twice a month, can slash harmful LDL cholesterol levels by about 50%. Studies are under way to see if any of these experimental agents, called PCSK9 inhibitors, prevent heart attacks or improve heart disease survival. Replacing...

Postoperative Atrial Fibrillation After Thoracic Aortic Surgery

What is the best approach in a patient with a failed aortic bioprosthetic valve: transcatheter aortic valve replacement or redo aortic valve replacement?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether transcatheter aortic valve-in-valve replacement (viv-TAVR) or redo aortic valve replacement (rAVR) is the best strategy in a patient with a degenerative bioprosthetic aortic valve. Altogether, 162 papers were found using the reported search, of which 12 represented the best evidence to answer the question. The authors, journal, date, country of publication, patient group, study type, outcomes and results of papers are tabulated. The results of the studies provided interesting results.

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.

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.
