Objectives: To compare the in-hospital outcomes of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in nonagenarians.
Background: Data comparing the outcomes of TAVR versus SAVR in nonagenarians are limited.
Methods: Using the National Inpatient Sample years 2012-2014, hospitalization data were retrieved for subjects aged ≥90 years who underwent TAVR or SAVR for severe aortic stenosis. The incidence of in-hospital mortality and peri-procedural outcomes were compared using unadjusted, multivariate logistic regression, and propensity score matched analyses.
Results: The final cohort included 6,680 records of nonagenarians undergoing aortic valve replacement, among which 5,840 (87.4%) underwent TAVR. There was no difference in the incidence of in-hospital mortality between both groups in the unadjusted (5.8% versus 6.0% P = 0.95), multivariate (odds ratio [OR] 0.78, 95% confidence interval [CI] 0.35-1.74), and propensity score matched (OR 1.07, 95% CI 0.75-1.51) analyses. In the propensity-matched analysis, TAVR was associated with a lower incidence of acute kidney injury (OR 0.58, 95% CI 0.47-0.72), post-operative blood transfusion (OR 0.51, 95% CI 0.43-0.61), a higher likelihood of discharge to home (OR 4.71, 95% 3.44-5.06), and a similar incidence of pacemaker placement (OR 1.16, 95% 0.89-1.53) and stroke (OR 1.34, 0.90-1.99).
Conclusions: In this nationwide analysis, TAVR was associated with an overall similar incidence of in-hospital mortality and less morbidity compared with SAVR. These findings suggest that TAVR is effective and safe in nonagenarians.

Platform Selection for Patients Undergoing Transcatheter Aortic Valve Replacement: A Practical Approach.

Transfemoral transcatheter aortic valve Replacement (TAVR) has become the standard therapy for patients with severe aortic stenosis in patients over 75 years old in Europe or 65 years old in the United States, regardless of the surgical risk. Furthermore, iterations of existing transcatheter aortic valves (TAVs), as well as devices with novel concepts, have provided substantial improvements with respect to the limitations of previous-generation devices. Hence, treatment of a broader spectrum of patients has become feasible, and a sophisticated selection of the appropriate TAV tailored to patients' anatomy and comorbidities is now possible.

The Ross procedure continues to be the best procedure to address unrepairable aortic valve pathology, especially in young adults. The Achilles heel of this procedure has been aortic root dilation and the potential need for a reoperation that may be associated with slightly increased risks in addition to the need for intervention on the pulmonary outflow tract. Modifying the Ross procedure by autograft inclusion inside a Dacron graft seems to have the potential advantage of stabilizing the autograft diameter, which may be associated with improved durability and decrease the need for future intervention.

Background: Severe aortic stenosis (AS) stratified by sex has been increasingly studied in the European population. Sex-specific outcomes in Asian patients with AS remain poorly defined. Hence, we aimed to study the clinical characteristics and impact of sex in moderate-to-severe AS, undergoing both invasive and conservative interventions in an Asian cohort over 10 years.

Background: A staging system based on cardiac damage for severe aortic stenosis (AS) has been validated for prognosis prediction following transcatheter aortic valve replacement (TAVR). Our study aims to investigate whether TAVR can lead to changes in cardiac damage shortly after the procedure and how these changes impact prognosis.
Method: Patients in this retrospective cohort study were classified into five stages (0-4) before TAVR based on the echocardiographic findings of cardiac damage.

The use of extracorporeal membrane oxygenation (ECMO) has emerged as a rescue intervention for hemodynamically unstable patients and prophylactic intraprocedural hemodynamic support in the cardiac catheterization laboratory. The prompt initiation of ECMO provides immediate hemodynamic support and allows for the completion of bridging and/or life-saving interventions. However, there are no clinical practice guidelines for the use of extracorporeal support in this area.
