Layer ‐specific deformation analysis in severe aortic valve stenosis, primary mitral valve regurgitation, and healthy individuals validated against invasive hemodynamic measurements of heart function
ConclusionLayer‐specific myocardial strain (LSS) patterns differed in patients with severe AS, significant MR, and healthy individuals with highest values in MR. Strain irrespective of layer assessed was associated with LV wall stress but seemed less related to contractility and unrelated to stroke work in the setting of normal LVEF.

Transubclavian approach: A competitive access for transcatheter aortic valve implantation as compared to transfemoral
ConclusionsOur study suggests that TSc approach may be, not only an alternative route to TF approach for TAVI, but even a competitive one in certain patients with increased risk of femoral injury.

Comparative outcomes of transcatheter aortic valve replacement in African American and Caucasian patients with severe aortic stenosis
ConclusionsThere was no significant difference in the utilization rates, in‐hospital outcomes, and cost of TAVR between Caucasians and AA patients in contemporary US practice. Further comparative studies of surgical and TAVR in AAs and other racial minorities are warranted.

Comparison of local versus general anesthesia in patients undergoing transcatheter aortic valve replacement: A meta ‐analysis
ConclusionOur meta‐analysis suggests that use of LA for TAVR is associated with a lower 30‐day mortality, shorter procedure time, fluoroscopy time, ICU LOS, hospital length of stay, and reduced need for inotropic support.

Comorbidities and Complications in Nonagenarians Undergoing Coronary Angiography and Intervention.
Authors: Gayed M, Yadak N, Qamhia W, Daralammouri Y, Ohlow MA Abstract Elderly people represent the fastest growing portion of cardiovascular patients. We aimed to analyze the clinical presentation, risk factors, co-morbidities, complications, and mortality in patients 90 years or more who underwent coronary angiography and intervention.We retrospectively studied 108 (0.25% of 43,385) consecutive patients ≥ 90 years undergoing cardiac catheterization and/or intervention in a tertiary specialist hospital between 2003 and 2014.Most patients (68.5%) were introduced on an emergency basis, especially with acute corona...

Direct percutaneous transaxillary implantation of a novel self ‐expandable transcatheter heart valve for aortic stenosis
ConclusionsOur study suggests that the implantation of the second‐generation self‐expandable ACURATE Neo™ via a transaxillary access is technically feasible and safe and yields excellent short‐term clinical results. © 2017 Wiley Periodicals, Inc.

End ‐stage renal disease and severe aortic stenosis: Does valve replacement improve one‐year outcomes?
ConclusionsPatients with ESRD and severe AS have a similar and higher survival with TAVR or SAVR when compared to BAV at 1‐year. These results may influence patient care decisions favoring valve replacement in AS patients with ESRD. © 2016 Wiley Periodicals, Inc.

Procedural and 30 ‐day clinical outcomes following transcatheter aortic valve replacement with lotus valve: Results of the RELEVANT study
ConclusionsRELEVANT study showed that TAVR using Lotus, in a real‐world population of patients with severe aortic stenosis at high surgical risk, was associated with excellent device success implantation and early safety according to VARC‐2 definition. The pacemaker implantation rate was about a third of patients. © 2017 Wiley Periodicals, Inc.

The Functional Significance of Paradoxical Low-Gradient Aortic Valve Stenosis: Hemodynamic Findings During Cardiopulmonary Exercise Testing
Conclusions In symptomatic patients with PLGAS, the capacity to dynamically reduce vascular and valvular loads determines the effect of exercise on PCWP, which, in turn, conditions the functional status. A critically fixed valvular obstruction may not be the main mechanism of functional impairment in a large proportion of patients with PLGAS. Exercise echocardiography is suitable to study the dynamics of PLGAS.

Prospective comparison between three TAVR devices: ACURATE neo vs. CoreValve vs. SAPIEN XT. A single heart team experience in patients with severe aortic stenosis
ConclusionsIn a “real world” registry, ACT compared favorably against the well‐studied SXT and MCV devices in both safety and efficacy. MCV implantation was associated with lower device success rates and higher rates of new permanent pacemaker implantation. © 2016 Wiley Periodicals, Inc.

CONCLUSIONS: Successful TAVR results in immediate and sizeable improvements in SV and CI, reductions in left and right ventricular filling pressures, and marked reductions in systemic and pulmonary vascular resistances. PMID: 27989060 [PubMed - in process]

The outcomes of transcatheter aortic valve replacement in a cohort of patients with end‐stage renal disease
ConclusionsPatients with ESRD who undergo TAVR are at high risk for mortality and complications. TAVR outcomes are comparable to but not substantially better than those with SAVR. Transfemoral TAVR seems to be at least as safe and effective as the current standard SAVR in patients undergoing aortic valve replacement. © 2016 Wiley Periodicals, Inc.

Efficacy and safety of transcatheter aortic valve replacement in intermediate surgical risk patients: A systematic review and meta‐analysis
ConclusionsIn this meta‐analysis we found that TAVR may be an acceptable alternative to SAVR in patients with intermediate risk for surgery. However, we must await evidence from the current large randomized trials before widespread adoption of this procedure is undertaken. © 2016 Wiley Periodicals, Inc.
