Mechanical Versus Bioprosthetic Aortic Valve Replacement in Patients Aged 40 to 70 Years: A Systematic Review and Meta-Analysis
Publication date: Available online 12 January 2016 Source:The Annals of Thoracic Surgery Author(s): James J. Wu, Michael Seco, James B. Edelman, Guy D. Eslick, Michael K. Wilson, Michael P. Vallely, Michael J. Byrom, Paul G. Bannon Prosthetic valve choice for middle-aged adults undergoing aortic valve replacement is a complex decision. Database searches identified 13 studies comparing mechanical and bioprosthetic valves in aortic valve replacement patients aged 40 to 70 years. No significant difference was found at 15 years for survival, freedom from stroke, and freedom from endocarditis. Mechanical valves were a...

Moderate Ischemic Mitral Regurgitation After Posterolateral Myocardial Infarction in Sheep Alters Left Ventricular Shear but Not Normal Strain in the Infarct and Infarct Borderzone
Conclusions Moderate CIMR alters radial circumferential shear strain after posterolateral MI in sheep. Further studies are needed to determine the effect of shear strain on myocyte hypertrophy and the effect of mitral repair on myocardial strain.

Outcomes on Continuous Flow Left Ventricular Assist Devices: A Single Institutional 9-Year Experience
Conclusions These data indicate excellent survival for BTT and DT patients on long-term LVAD support. However, for LVAD therapy to become a plausible alternative to heart transplantation, we need to further decrease the incidence of postoperative complications.

Branched Endovascular Therapy of the Distal Aortic Arch: Preliminary Results of the Feasibility Multicenter Trial of the Gore Thoracic Branch Endoprosthesis
Conclusions Total endovascular repair of distal zone 2 arch aortic aneurysms can be achieved with a novel branched arch endograft. Future studies will evaluate the feasibility of this approach for aneurysms encompassing the brachiocephalic trunk and left carotid artery.

Reexploration for Bleeding and Its Association With Mortality After Cardiac Surgery
Conclusions Excessive bleeding leading to reexploration is associated with a twofold increased early postoperative mortality rate. Reexploration for bleeding is also associated with mortality beyond 90 days after operation.

Scimitar Syndrome Repair in Adults: Intermediate-Term Results Using an Extracardiac Conduit
Conclusions Correction of scimitar syndrome with an extracardiac conduit can be easily and safely performed in adults, with excellent intermediate-term durability, without graft thrombi or stenosis. This technique avoids deep hypothermic circulatory arrest when the SV is short or enters the IVC in an unusually caudad location.

Long-Term Outcome and Valve Surgery for Infective Endocarditis in the Systematic Analysis of a Community Study
Conclusions In unselected patients with IE, prognostic factors for long-term mortality were consistent with those identified in previous studies for short-term mortality. These results confirm the apparent benefit associated with valve surgical procedures on long-term prognosis.

Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement for Severe Aortic Stenosis in Patients With Chronic Kidney Disease Stages 3b to 5
Conclusions CKD stages 3b to 5 increases the risk of mortality after TAVI and SAVR. In this subset of patients, SAVR was associated with somewhat better early and late survival. The risk of acute kidney injury was higher after SAVR. These findings suggest that CKD stages 3b to 5 does not contraindicate SAVR. Strategies to prevent severe acute kidney injury should be implemented with either SAVR or TAVI.

Anterior Leaflet Augmentation With CorMatrix Porcine Extracellular Matrix in Twenty-Five Patients: Unexpected Patch Failures and Histologic Analysis
Conclusions For type III MR, a large anterior leaflet patch technique with porcine ECM was associated with a 32% recurrence rate of severe MR related directly to patch failure. Further research and development should be performed on the use of ECM materials with a goal to decrease the failure rate experienced in this study.

Prolonged Cross-Clamping During Aortic Valve Replacement Is an Independent Predictor of Postoperative Morbidity and Mortality: Analysis of the Japan Cardiovascular Surgery Database
Conclusions Prolonged ACCD offers an independent predictor of postoperative morbidity and mortality after isolated AVR for AS despite recent technologic advances and surgical refinements.

The Racial Paradox in Multiarterial Conduit Utilization for Coronary Artery Bypass Grafting
Conclusions Despite similar rates of arterial grafting for black patients and white patients in this large single-center cohort, black patients continued to have significantly worse late survival when compared with white patients. Continued evaluation as to the causes of this disparity is warranted.

Outcomes of Dialysis-Dependent Patients After Cardiac Operations in a Single-Center Experience of 483 Patients
Conclusions Patients with DD CRF undergoing cardiac operations have high perioperative and medium-term mortality, particularly in the presence of combined aortic and mitral valve pathologic conditions, active endocarditis, and poor left ventricular function.

Clinical Outcomes of the David V Valve-Sparing Root Replacement Compared With Bioprosthetic Valve-Conduits for Aortic Root Aneurysms
Conclusions VSRR and BIO result in equivalent operative mortality and morbidity with similar midterm survival and valve durability. VSRR is an effective alternative to BIO for aortic root pathologic conditions; however, careful patient selection is paramount.

Aortic Remodeling After Endovascular Repair of Complicated Acute Type B Aortic  Dissection
Conclusions TEVAR for complicated aTBAD results in low 30-day and 1-year mortality rates, with higher reintervention rates than observed with open operations. TEVAR is effective in thrombosing and stabilizing the size of the thoracic FL. The abdominal aortic FL remains patent and must be carefully scrutinized for long-term aneurysm formation.
