Transcatheter Aortic Valve Implantation in Nonagenarians
Conclusions: Transcatheter aortic valve implantation can be performed in nonagenarians despite very high preoperative risk scores and substantial multimorbidity, with acceptable outcomes.

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.

Aortic Valve Replacement in the Moderately Elevated Risk Patient: A Population-Based Analysis of Outcomes.
CONCLUSIONS: This population-based contemporary assessment suggests moderate-risk patients undergoing AVR experience favorable outcomes. Although increasing PROM is important in preoperative evaluation of risk, preexisting pulmonary hypertension and indication for operation are among other factors that should be considered as TAVR expands into this group of patients.

Simplified prediction of postoperative cardiac surgery outcomes with a novel score: R2CHADS2
Conclusion The R2CHADS2 score estimates postoperative events with acceptable accuracy and if further validated may be used as a simple preoperative risk tool calculator.

WITHDRAWN: Preoperative statin therapy for patients undergoing cardiac surgery.
CONCLUSIONS: Preoperative statin therapy reduces the odds of postoperative atrial fibrillation (AF) and shortens the patient's stay on the ICU and in the hospital. Statin pretreatment had no influence on perioperative mortality, stroke, myocardial infarction or renal failure, but only two of all included studies assessed mortality. As analysed studies included mainly individuals undergoing myocardial revascularisation, results cannot be extrapolated to patients undergoing other cardiac procedures such as heart valve or aortic surgery.

Does a Higher Society of Thoracic Surgeons Score Predict Outcomes in Transfemoral and Alternative Access Transcatheter Aortic Valve Replacement?
Conclusions As expected, non-TF patients were at a higher risk than TF patients for procedural morbidity and death. Although no differences were observed in 30-day deaths or morbidity in different STS PROM subgroups, those undergoing non-TF TAVR at a higher STS PROM (>8%) had higher 1-year mortality. When applicable, TF TAVR remains the procedure of choice in high- or extreme-risk patients undergoing TAVR.

The Midterm Impact of Transcatheter Aortic Valve Replacement on Surgical Aortic Valve Replacement in Michigan
Conclusions TAVR implementation in Michigan has dramatically increased overall SAVR volume. This phenomenon has occurred with a concomitant decrease in preoperative risk profile and has improved early SAVR outcomes, particularly at TAVR hospitals, but surprisingly not in patients considered at high preoperative risk. As TAVR use increases, these issues may be further clarified and elucidated.

Transcatheter Aortic Valve Implantation versus Surgical Aortic Valve Replacement: Meta-Analysis of Clinical Outcomes and Cost-Effectiveness.
Conclusions The present study demonstrated no significant differences in regards to mortality or stroke between the two therapeutic procedures. However, the cost-effectiveness and long-term efficacy of TAVI may require further investigation. Technological improvement and increased experience may broaden the clinical indication for TAVI for low-intermediate risk patients in the future. PMID: 26891807 [PubMed - as supplied by publisher]

Medtronic wins expanded PMA for CoreValve
The FDA cleared expanded indications for Medtronic‘s (NYSE:MDT) CoreValve TAVR devices, now cleared for use in patients with end-stage renal disease and those with low-grade, low-flow aortic stenosis. Medtronic won approval from the FDA to modify the CoreValve’s labeling in November which included both its CoreValve and CoreValve Evolut R systems. The changes to the labeling were approved based on Medtronic’s CoreValve U.S. expanded use study of high and very-high-risk subjects at need for aortic valve replacements, according to an email FierceMedicalDevices received from a Medtronic spokesperson. Data from theÂ...

Short-term and medium-term outcomes of transapical aortic valve implantation as a single-strategy approach: one center's experience.
CONCLUSIONS: The TA-TAVI approach provides good results in terms of early and midterm outcomes. This approach is feasible and safe for patients who have high surgical risk. PMID: 26336490 [PubMed]

Extra-anatomic revascularization for preoperative cerebral malperfusion due to distal carotid artery occlusion in acute type A aortic dissection AORTIC SURGERY
CONCLUSION Extra-anatomic bypass for LCCA or RCCA occlusion allows for early selective cerebral perfusion during AADA repair, and may reduce the risk of neurological complications in patients with preoperative cerebral malperfusion.
