Aortic regurgitation: from mechanisms to management
The scope of treatment for aortic regurgitation has widened with the continued evolution of transcatheter aortic valve implantation (TAVI). In a state-of-the- art review, Andreas Baumbach, Alexander R. Tamm and colleagues cover the epidemiology and assessment of aortic regurgitation as well as the current treatment options and devices available today.
French experience of TAVI for AR
Robin Le Ruz, Vincent Letocart and colleagues report on procedural safety and long-term clinical events in pure aortic valve regurgitation patients treated with new-generation devices. TAVI is found
to be efficient and reasonably safe, but preventing a second valve implantation
is found to be the main challenge in this population, who remain at high risk even after a successful procedure.
OFDI vs IVUS in PCI for ACS
Hiromasa Otake, Takashi Akasaka and colleagues compare intravascular and optical frequency domain imaging (OFDI) guidance in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). With high procedural success and comparable minimum lumen areas between the two groups at 8-month follow-up, the authors suggest that OFDI may be an option for guiding PCI in ACS patients.
Coronary artery innervation in humans
Mert Tokcan, Felix Mahfoud and colleagues bring us a quantitative analysis of coronary artery innervation in humans. Analyses of nerve fibres show that their density, size and distribution vary significantly between the coronary arteries. The authors hope that a more profound understanding of these innervation patterns can help to optimise neuromodulation techniques and advance the possibility of less invasive catheter-based approaches.
PCI and acute ischaemic strokes
In a meta-analysis spanning 16 years, Benjamin Bay, Christoph Waldeyer and colleagues describe an increasing trend in acute ischaemic stroke, investigating predictors of stroke and rates of in-hospital mortality in patients undergoing PCI.
