Heart failure

Bioprinting, the production of tissue by 3D printing, is a rapidly emerging technology with high potential for tissue engineering also in cardiac surgery. The paper provides insight in currently available techniques, opportunities for application and perspectives of this revolution in medicine.

In this multi-institution randomized trial, patients with heart failure underwent daily telemonitoring and standard care or just standard care.  At 1 year, fewer patients in the telemonitoring group had worsened composite score (19% vs 27%) and experienced fewer deaths (10 vs 27 pts).

The authors of this study investigated the effect of myectomy on pulmonary hypertension in patients with hypertrophic cardiomyopathy (HCM).

In this study, the authors identify a number of markers in cardiac stem cells obtained from 38 patients undergoing coronary artery bypass grafting which appear to predict positive myocardial remodelling at 12 months following surgery

The authors present results of surgery in 12 pts for hypertrophic cardiomyopathy extending to the papillary muscles.  Repair was performed through a detached anterior mitral leaflet, which was subsequently repaired.  The intraventricular end-diastolic gradient was decreased by 80% postop, and mitral regurgitation that was present preop was eliminated

Results of a 50 year experience with surgery for cortriatriatum sinister were summarized.  A mix of infants and adults underwent treatment, consisting of membrane excision on CPB.  10 year survival was 83%, and all patients were in NYHA class I or II at follow-up.

This video shows a female toddler with diagnosed idiopathic dilated cardiomyopathy. The patient presented with worsening symptoms of congestive heart failure and was treated with the help of a left ventricular assist device.

This study of 389 pts receiving a continuous flow LVAD evaluated the risk of thromoembolic (TE)complications associated with preop AF.   TE occured in 25% of pts; freedom from TE at 2 years was 46% in those with AF and 72% in those without AF (p<0.001).  AF did not affect late survival.

This article describes how a HeartMate XVE left ventricular assist device may be exchanged for a HeartMate II axial-flow pump with low morbidity and mortality and without a full sternotomy.
