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...

Comparison of expected and observed outcomes for septal myectomy in hypertrophic obstructive cardiomyopathy
ConclusionsSeptal myectomy, performed in a tertiary referral center, had a 30-day mortality rate of 0% and low morbidity rate. There was no difference between observed myectomy mortality and STS Calculator predicted risk for AVR and MV repair. It is possible that a larger sample could reveal lower mortality than STS prediction.

Rationale and design of the randomized, controlled early valve replacement guided by biomarkers of left ventricular decompensation in asymptomatic patients with severe aortic stenosis (EVOLVED) trial
ConclusionThe EVOLVED trial is the first multicenter randomized controlled trial to compare early aortic valve replacement to routine care in asymptomatic patients with severe aortic stenosis and mid-wall LGE.

Risk stratification and clinical outcomes after surgical pulmonary valve replacement
ConclusionPatients undergoing PVR at larger RV volumes had similar survival but more overall CAE. A larger study population with a longer follow-up will be required to determine if early PVR provides survival benefit in the long-term.

DangasTranscatheter aortic valve implantation, also called transcatheter aortic valve replacement (TAVR), is the treatment of choice for patients with severe aortic stenosis and intermediate to high operative risk. A significant portion of TAVR patients have atrial fibrillation (AF) requiring chronic oral anticoagulation. In moderate...

Oral anti-Xa anticoagulation after Trans-Aortic Valve Implantation for Aortic Stenosis: The randomized ATLANTIS trial
Conclusions ATLANTIS tests the superiority of an apixaban-based strategy versus the recommended standard of care strategy to reduce the risk of post-TAVR thromboembolic and bleeding complications in an all comer population.

Cardiovascular events and hospital resource utilization pre – and post–transcatheter mitral valve repair in high–surgical risk patients
Conclusions MitraClip was associated with a reduced rate of all-cause and HF hospitalizations and an increased rate of bleeding hospitalizations. One-year Medicare costs were reduced in those who survived a full year after the MitraClip procedure. Payors and providers seeking to reduce HF hospitalizations and associated Medicare costs may consider MitraClip among appropriate patients likely to survive 1 year.

Factors associated with non –vitamin K antagonist oral anticoagulants for stroke prevention in patients with new-onset atrial fibrillation: Results from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II (ORBIT-AF II)
Conclusions In contemporary clinical practice, up to three-fourths of patients with new-onset AF are now initially treated with a NOAC for stroke prevention. Those selected for NOAC treatment had lower stroke and bleeding risk profiles, were more likely treated by cardiologists, and had higher socioeconomic status.

Trial design: Rivaroxaban for the prevention of major cardiovascular events after transcatheter aortic valve replacement: Rationale and design of the GALILEO study
Conclusions GALILEO will test the hypothesis that a rivaroxaban-based antithrombotic strategy reduces the risk of thromboembolic complications post-TAVR with an acceptable risk of bleeding compared with the currently recommended antiplatelet therapy–based strategy in subjects without need of chronic oral anticoagulation.

Leon Background Co-existence of moderate aortic stenosis (AS) in patients with heart failure with reduced ejection fraction (HFrEF) is not uncommon. Moderate AS increases afterload, while pharmacological reduction of afterload is a pillar of contemporary...

Progressive Intermediate-Term Improvement in Ventricular and Atrioventricular Interaction after Transcatheter Pulmonary Valve Replacement in Patients with Right Ventricular Outflow Tract Obstruction
Conclusions Patients with RVOT obstruction had biventricular systolic and diastolic dysfunction at BL. Relieving RVOT obstruction with TPVR reduced adverse ventricular and compensatory atrioventricular interaction, resulting in progressive biventricular functional improvement and remodeling at early and mid-term FU.
