The authors, using the STS/ACC TVT Registry, analyzed the the occurrence of patient-prosthesis mismatch (PPM) in 62,215 patients enrolled between 2014 and 2017. They found that severe and moderate PPM occurred in 12% and 25% of patients, respectively.
Cost-Effectiveness of Transcatheter Versus Surgical Aortic Valve Replacement in Patients With Severe Aortic Stenosis at Intermediate Risk: Results From the PARTNER 2 Trial
December 18, 2018
This study analyzed the cost-effectiveness of TAVR versus SAVR in 3110 intermediate-risk aortic stenosis patients from the PARTNER-2 trial. Using a Markov model, the authors found that TAVR is economically dominant from the perspective of lifetime cost-effectiveness in the US healthcare system.

Patient Care and General Interest Truly remote percutaneous coronary intervention was performed in five human patients at Apex Heart Institute in Ahmedabad, India.
Clinical Leaflet Thrombosis in Transcatheter and Surgical Bioprosthetic Aortic Valves by Four-Dimensional Computed Tomography
December 10, 2018
Basra and colleagues report that among patients with bioprosthetic aortic valves who had clinical or echocardiographic indications suggestive of leaflet thrombosis, one-third of patients had this diagnosis confirmed by four-dimensional computed tomography (4DCT).

Hebeler and colleagues hypothesized that the inclusion of measures of frailty might improve the prediction of mortality one-year after transcatheter aortic valve replacement (TAVR).
Feasibility of Transcatheter Aortic Valve Implantation in Patients With Coronary Heights ≤7 mm: Insights From the Transcatheter Aortic Valve Implantation Karlsruhe Registry
November 19, 2018
Conzelmann and colleagues aimed to gain information about outcomes of transcatheter aortic valve replacement (TAVR) procedures in patients with coronary heights less than 7 mm. These procedures are not common, as one of the contraindications for TAVR is a low coronary height.
