Transcatheter treatment of native aortic valve regurgitation: Results from an international registry using the transfemoral ACURATE neo valve
ConclusionsThis multicenter study suggests good feasibility and early safety of transfemoral TAVR with the self-expandable ACURATE neo device in patients with severe NAVR refused for surgery. Rates of moderate PVL, new pacemaker implantation and need for a second valve were higher than those reported for TAVR in aortic stenosis.

Transcatheter aortic valve replacement for patients with severe bicuspid aortic stenosis
ConclusionsThis initial experience suggests TAVR can be safely performed in patients with BAV achieving similar short-term procedural and clinical outcomes when compared with patients with TAV.Condensed AbstractThe outcomes of 50 patients (8.8%) with bicuspid aortic stenosis (BAV) undergoing TAVR were compared with those of 517 patients (91.2%) with trileaflet aortic valve (TAV) stenosis. Patients with BAV were younger, had higher prevalence of COPD, lower prevalence of CAD, higher BMI and lower STS score. Major complications were similar between the groups, including stroke (2.0% vs. 1.5, P = .567), 30-day all-c...

Valve-in-Valve Transcatheter Implantation versus Redo Surgical Aortic Valve Replacement
Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) for a failing prosthesis is an appealing alternative to redo surgical AVR. We utilized data from the US National Inpatient Sample for the period 2012-2016 to identify hospitalizations for either ViV-TAVI or redo-SAVR. The primary outcomes of interest were in-hospital adverse events composite outcome (comprising of mortality, myocardial infarction, stroke, or acute kidney injury) and all-cause mortality. We used propensity score matching to adjust for the baseline differences between ViV-TAVI and redo-SAVR cohorts.

Between a Rock and a Hard Place: How to Use Antithrombotics in Patients Undergoing Transcatheter Aortic Valve Replacement
Transcatheter aortic valve replacement (TAVR) has become the preferred method for management of severe aortic stenosis in patients who are at high and intermediate surgical risk. Short-term data have been presented from two studies comparing TAVR versus surgical aortic valve replacement (SAVR) in low surgical risk patients. The Placement of Aortic Transcatheter Valves 3 (PARTNER 3) trial compared TAVR using a balloon expandable valve with standard SAVR. The primary endpoint was a composite of all-cause mortality, stroke, or re-hospitalization at 1 year post-procedure.

Transcatheter vs surgical aortic valve replacement in patients with interstitial lung disease
ConclusionsAmong ILD patients with symptomatic aortic stenosis, TAVR was associated with comparable operative and risk ‐adjusted 1‐year survival to SAVR. TAVR patients also had shorter ventilator times, ICU and hospital stay despite being at higher risk. Together, our findings suggest that TAVR may be a better option in this unique cohort.

Changes in left and right ventricular longitudinal function after pulmonary valve replacement in patients with Tetralogy of Fallot.
In conclusion, there is a clear atrioventricular coupling in patients before PVR that is lost after PVR, possibly due to loss of pericardial integrity. Impaired atrioventricular coupling complicates assessment of ventricular function after surgery using measurements of longitudinal function. Changes in atrioventricular coupling seen in patients with rToF may be energetically unfavourable and long-term effects of surgery on atrioventricular coupling is therefore of interest. Also, AVPD and GLS cannot be used interchangeably to assess longitudinal function in rToF. PMID: 31886724 [PubMed - as supplied by publisher]

Transcatheter aortic valve implantation versus surgical aortic valve replacement for severe aortic stenosis in people with low surgical risk.
CONCLUSIONS: Our meta-analysis indicates that, in the short term, TAVI probably has little or no mortality difference compared to SAVR for severe AS in individuals with low surgical risk. Similarly, there is probably little or no difference in risk of stroke, MI, and cardiac death between the two approaches. TAVI may reduce the risk of rehospitalisation, but we are uncertain about the effects on LOS. TAVI reduces the risk of atrial fibrillation, AKI, and bleeding. However, this benefit is offset by the increased risk of PPM implantation. Long-term follow-up data are needed to further assess and validate these outcomes, esp...

A Case of Successful Treatment of Cerebral Embolism Using Endovascular Thrombectomy Immediately After Transcatheter Aortic Valve Implantation
TRANSCATHETER aortic valve implantation (TAVI) is a less invasive alternative to surgical aortic valve replacement in high-risk patients with severe aortic stenosis. However, there are increasing concerns about the potential complications of TAVI now that its indications have been expanded to include patients with low-to-intermediate surgical risk.1,2 One of the serious complications of TAVI is stroke. It is known that there is an increase in 30-day mortality, rates of respiratory insufficiency and postprocedural delirium, and duration of hospital stay if stroke occurs.

The contemporary role of echocardiography in the assessment and management of aortic stenosis
AbstractAortic stenosis (AS) represents a major healthcare issue because of its ever-increasing prevalence, poor prognosis, and complex pathophysiology. Echocardiography plays a central role in providing a comprehensive morphological and hemodynamic evaluation of AS. The diagnosis of severe AS is currently based on three hemodynamic parameters including maximal jet velocity, mean pressure gradient (mPG) across the aortic valve, and aortic valve area (AVA). However, inconsistent grading of AS severity is common when the AVA is < 1.0 cm2 but the mPG is < 40 mmHg, also known as low-gradient AS (LGAS). Spec...

AbstractThe total artificial heart (TAH) is a form of mechanical circulatory support that involves resection of the native ventricles followed by placement of a device that can restore total pulmonary and systemic flow.

Research Articles Ventricular stroke work and vascular impedance refine the characterization of patients with aortic stenosis
Aortic stenosis (AS) management is classically guided by symptoms and valvular metrics. However, the natural history of AS is dictated by coupling of the left ventricle, aortic valve, and vascular system. We investigated whether metrics of ventricular and vascular state add to the appreciation of AS state above valve gradient alone. Seventy patients with severe symptomatic AS were prospectively followed from baseline to 30 days after transcatheter aortic valve replacement (TAVR). Quality of life (QOL) was assessed using the Kansas City Cardiomyopathy Questionnaire. Left ventricular stroke work (SWLV) and vascular impedance...
