This is a retrospective review of 143 patients requiring reoperation after an initial AVR with a Freestyle® stentless bioprosthesis. Valve survival was 10.4 years for those with structural valve deterioration, but it was much less (4.1 years) if the initial procedure was for infective endocarditis. Operative mortality was <2%. This suggests a favourable result for reoperation.
A baby in Taiwan is the third-lightest to have undergone repair of a type A interrupted aortic arch and aortopulmonary window.

Researchers from Canada find an increased risk of cardiovascular disease in women whose infants were born with congenital heart defects.
Researchers from around the USA have reported an approach for avoiding transcatheter aortic valve replacement-induced coronary obstruction, and their technique will be evaluated in a multicenter study.
Bhatnagar and colleagues randomized patients with malignant pleural effusion in order to test an outpatient approach to pleurodesis. All patients had indwelling pleural catheters placed for drainage, and they received a daily administration of either talc slurry or placebo through the catheter on an outpatient basis. Pleurodesis was evaluated after 35 days, with 30 of 69 patients (43%) in the talc group and 16 of 70 patients (23%) in the placebo group demonstrating successful pleurodesis.
The EJCTS and ICVTS are publishing a series of Statistical Primers to help clinicians perform and interpret research. In this article, Hickey and colleagues provide a practical introduction to repeated-measures analysis. The authors focus on linear mixed models, which are more amenable to real world data than other methods given their ability to handle mistimed or randomly missing longitudinal data. This primer on a more advanced statistical method could provide crucial information to increase the impact of your next manuscript.
Gosev and colleagues evaluated the baseline characteristics and outcomes in 156 patients from 12 centers who survived at least four years on left ventricular assist device (LVAD) support. Among this group of patients, mean survival was 7.1 years (95% CI 6.7 to 7.5 years). The average readmission rate was 1.1 ± 0.9 per patient-year, and the authors suggest that this low rate of complications could be responsible for the long survival seen in these patients.
70-year-old Arnold Schwarzenegger has undergone successful redo heart surgery at Ceders-Sinai Hospital, after an initial attempt to replace his pulmonic valve percutaneously. He famously underwent an attempted Ross Procedure in 1997, and the pulmonic valve left from that operation now required repeat surgery.
Apparently everything went well, and his first words were "I'm back!"

A study of data from the German Aortic Valve Registry suggests that rapid deployment valves lead to shorter surgery duration but not to better outcomes than conventional biological valves.
An observational study from Denmark, published in JAMA Cardiology, found that the risk of thromboembolism from atrial fibrillation (AFib) that began after coronary artery bypass grafting was lower than that seen with nonsurgical, nonvalvular AFib, despite a lower rate of oral anticoagulation therapy.
Researchers in South Africa find that silver-based anticancer drugs show promise in preclinical studies, potentially representing an opportunity to design chemotherapeutic drugs on a less expensive starting material than the current platinum-based drugs.
