Swiss operators described the first-in-human placement of the novel Tricento transcatheter heart valve, in a woman with severe tricuspid regurgitation. Three months after the procedure, caval vein regurgitant volume was reduced and the patient showed symptomatic and clinical improvement, they reported in EuroIntervention.
In the same journal, researchers said transaortic and transfemoral aortic valve replacement were associated with similar rates mortality rates in a propensity score-matched analysis. However, the transaortic approach was tied to more new-onset atrial fibrillation, life-threatening bleeds, and transfusions. (EuroIntervention)
Older recipients of aortic valve replacement were more likely to die within the year if they went into the surgical or transcatheter procedure malnourished. (Circulation)
Researchers are developing a micropacemaker system (5 mm × 2.4 cm) that is placed percutaneously and functions entirely in the pericardial space. They optimized the insertion method by experimenting on six pigs. (Circulation: Arrhythmia and Electrophysiology)
The Sentinel cerebral embolic protection system caught debris in 99% of patients undergoing transcatheter aortic valve replacement, according to a study that pooled patients from the SENTINEL and SENTINEL-H studies. Captured particles were especially large and more numerous when the patient got Evolut R and Lotus valves. (JACC: Cardiovascular Interventions)
Taking the quantitative flow ratio during invasive coronary angiography is feasible and better than angiographic assessment in the evaluation of intermediate coronary stenoses, a study in patients with stable angina showed. This potentially broadens “access to physiological lesion assessment in diagnostic catheterization laboratories and centers with low adoption of pressure‐wire–based diagnostic strategies,” the investigators said.

Percutaneous coronary intervention on chronic total occlusions may have a beneficial effect on left ventricular remodeling, according to a meta-analysis in the Journal of Interventional Cardiology.
