Echocardiographic determinants of LV functional improvement after transcatheter aortic valve replacement
ConclusionsIn patients undergoing TAVR with depressed LV function, those who failed to improve were more likely to have relatively higher LVEF, SV, and SVI; and lower E, E/E′, and PASP at baseline. Mortality rates were found to be higher in persistent LV dysfunction group. © 2015 Wiley Periodicals, Inc.

Transcatheter aortic valve implantation for paradoxical low‐flow low‐gradient aortic stenosis patients
ConclusionAs opposed to LEF‐LG patients, mid‐term prognosis after TAVI procedure in PLFLG patients is similar to HGAS patients despite higher perioperative mortality. © 2015 Wiley Periodicals, Inc.

A novel approach to extraction of a large thrombus on the intraventricular guide‐wire during transcatheter aortic valve replacement
We report a case where a large guide‐wire thrombus identified during TAVR was successfully removed using a novel approach, preventing a potentially major stroke in this high‐risk patient. © 2015 Wiley Periodicals, Inc.

Prognosis importance of low flow in aortic stenosis with preserved LVEF
Conclusions In patients with severe AS and preserved LVEF, LF, as assessed using cardiac catheterisation is frequent, and is an independent predictor of mortality. Consequently, the measurement of SVi should be systematically included in the assessment of these patients.

Stroke Volume Adjusted to Afterload for Assessment of Cardiac Performance in Patients with Severe Aortic Stenosis and Preserved Left Ventricular Ejection Fraction
Objectives: The aim of this study was to evaluate the relationship between valvular resistance and stroke volume (SV) and to assess SV adequacy to afterload in patients with severe aortic stenosis (AS) and normal left ventricular ejection fraction (LVEF). Methods: We assessed clinical characteristics and echocardiographic parameters in 44 patients with isolated severe AS and preserved LVEF. LV end-diastolic pressure (LVEDP) and LV mean diastolic pressure (LVMDP) were measured by cardiac catheterization. SV values were plotted in relation to valvular resistance. Patients were divided into 2 groups, with an SV that was highe...

Quantification of low-gradient severe aortic stenosis using a hybrid approach combining Doppler echocardiography and thermodilution.
CONCLUSION: The hybrid method is reasonably accurate in assessing AVA in patients with low-gradient severe AS. Although the continuity equation should be used in routine clinical practice in most patients, this method could serve as an alternative when the LVOT diameter and/or velocities seem questionable.

The Case Files: When a Spade is Not a Spade
Turrin, Danielle DO; Sattler, Steven DO; Amodeo, Dana DO A 25-year-old Hispanic man presented to the emergency department with a complaint of three days of left-sided precordial chest pain. He described the pain as a constant 6/10 with pressure-like discomfort radiating to his left arm and the left side of his neck. He also experienced nausea, but denied any provocative or palliative factors. He said he had not experienced anything similar to this before. He had no family history of heart disease, acute myocardial infarction, or sudden cardiac death. He admitted to a 1.5 pack-per-day smoking history and social alcohol use,...

Prevalence and predictors of carotid artery stenosis in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation
Conclusions: The prevalence of CAS in patients undergoing TAVI is high, exceeding that observed in patients undergoing catheterization for coronary indications. The impact of CAS on clinical outcomes following TAVI merits further research. © 2014 Wiley Periodicals, Inc.

Feasibility and efficacy of the 2.5 L and 3.8 L impella percutaneous left ventricular support device during high‐risk, percutaneous coronary intervention in patients with severe aortic stenosis
ConclusionImplantation of the 2.5 and 3.8 L Impella appears feasible in patients with severe AS and left ventricle (LV) impairment. A balloon‐assist technique may be used to facilitate device implantation when initial unassisted attempts fail. Improved hemodynamic stability may enhance the tolerability of lengthy and complex procedures. © 2014 Wiley Periodicals, Inc.

Successful management of a twice complicated case by implantation of three CoreValve prostheses
An 80year old man, diabetic on oral medication and with permanent atrial fibrillation with a single chamber pacemaker, was referred to our hospital for severe symptomatic aortic valve stenosis. His trans-thoracic echocardiography confirmed severe aortic stenosis with a mean/peak gradient of 45/85mmHg, an estimated aortic valve area of 0.7cm2 and good systolic function with an ejection fraction of 50%. His past medical history was remarkable for a minor stroke without neurological impairment and moderate kidney dysfunction with creatinine of 2.3mg/dL. A cardiac catheterization revealed no obstructive coronary heart disease.

Clinical outcomes of patients with low-flow, low-gradient, severe aortic stenosis and either preserved or reduced ejection fraction undergoing transcatheter aortic valve implantation
Conclusion TAVI in PLF-LG or LEF-LG patients is associated with overall mortality rates comparable with HGAS patients and all groups profit symptomatically to a similar extent.

Feasibility and safety of transfemoral implantation of Edwards SAPIEN XT prosthesis without balloon valvuloplasty in severe stenosis of native aortic valve
ConclusionsDirect implantation of Edwards SAPIEN XT without prior BV in selected cases is feasible and safe. The number of patients in whom this technique would be applicable, and their impact on reducing complications has to be determined. © 2013 Wiley Periodicals, Inc.
