One center is using 3-D models of aortic valves to predict how an implant would function. “We can model various therapies, positions and types of valves to better understand problems such as leakage, clotting or coronary obstruction,” a biomedical engineer there said. (Becker’s Hospital Review)
Turkish company Alvimedica hopes to manufacture stents domestically and export them to the U.S. (UrduPoint)
A new pacemapping algorithm can identify the exit site of ventricular arrhythmias based on three initial pacing points collected in the chamber of interest, according to a proof-of-concept study. It located the best pacemap site in 45 out of the 46 attempts, researchers reported in Europace.
The Chocolate percutaneous transluminal angioplasty balloon catheter was associated with improvement by 2.1 Rutherford classes 1 year after patients were treated for peripheral arterial disease (PAD). Patency was 64.1% at that point in the registry. (Catheterization and Cardiovascular Interventions)
Reperfusion delays in young ST-segment myocardial infarction patients may be predicted by female sex, positive voltage criteria for left ventricular hypertrophy, and absence of a prehospital ECG, according to a study in the Journal of the American Heart Association.
Procedural success and complication rates didn’t differ widely for left atrial appendage closure if patients had one of four typical morphologies (chicken wing, cauliflower, windsock, and cactus), investigators found from analyzing the LAARGE registry. Implantation success was less likely to be successful when patients had atypical anatomies, however. (EuroIntervention)
Blood sampling provides information on oxygen extraction fraction, which can help operators anticipate cerebral hyperperfusion syndrome occurring after carotid artery stenting, according to a report in the Journal of NeuroInteventional Surgery.
