Modeling of Valve-in-Valve Transcatheter Aortic Valve Implantation after Aortic Root Replacement Using 3-Dimensional Artificial Intelligence Algorithm.
Aortic root replacement requires construction of a composite valve-graft and reimplantation of coronary arteries. This study assessed the feasibility of valve-in-valve transcatheter aortic valve implantation after aortic root replacement. ⋯ Following aortic root replacement, all patients were candidates for valve-in-valve procedure using 1 or both types of transcatheter heart valves. Self-expanding valves may be at higher risk for stent frame deformation at graft anastomotic lines and balloon-expandable valves may be at higher risk of coronary obstruction.

Changes in Left Ventricular-Aortic Angulation Are Associated with the Development of Obstruction in Hypertrophic Cardiomyopathy.
To characterize changes in ventricular morphology in patients with hypertrophic cardiomyopathy who develop left ventricular (LV) outflow tract obstruction. ⋯ The development of LV outflow tract obstruction in patients with hypertrophic cardiomyopathy was associated with progressive LV outflow tract angulation and increased LV hypertrophy, as reflected by LV mass. Progression to obstruction was not related to changes in the mitral valve leaflet morphology.

Late Recurrence of Completely Resected Stage I-IIIA Lung Adenocarcinoma.
Research into the risk factors associated with late recurrence (>2 years after surgery) of lung adenocarcinoma is limited. We investigated the incidence of and clinicopathologic and genomic features associated with late recurrence of resected stage I-IIIA lung adenocarcinoma. ⋯ Late recurrence of lung adenocarcinoma after resection is more common than previously reported. Patients without disease more than 2 years after surgery who had aggressive pathologic features at the time of resection have an elevated risk of recurrence and may benefit from more aggressive follow-up.

For Your Consideration: Benefits of Listing as Willing to Consider Heart Offers from Donors with Hepatitis C.
Despite excellent outcomes of heart transplants from hepatitis C virus (HCV)-positive donors (D+), many candidates are not listed to even consider HCV D+ offers. ⋯ Willingness to consider HCV D+ heart offers was associated with a 37% lower risk of waitlist mortality and a 21% higher likelihood of receiving a transplant. We urge providers to encourage candidates to list as being willing to consider offers from donors with hepatitis C to optimize their waitlist outcomes and access to transplantation.
