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.

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.

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).

Coyan and colleagues report outcomes following double valve surgery in a cohort of patients who underwent operation between 2011 and 2017.

Using remodeling aortic and mitral annuloplasty rings, a double valve repair was accomplished in a young patient with Marfan syndrome.

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).

This single institution retrospective study examined the utility of using nonpledgeted sutures for aortic valve replacement. In short-term follow-up, 3.6% of patients had insignificant perivalvular leak and 0.9% had significant perivalvular leak requiring reoperation.
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.
