Multicenter Study Comparative StudyLong-term follow-up and comparison of techniques in radiofrequency ablation of ventricular arrhythmias originating from the aortic cusps (AVATAR Registry).
Radiofrequency ablation (RFA) of outflow tract ventricular arrhythmia (VA) that originates from the aortic cusps can be challenging. Data on long‑ term efficacy and safety as well as optimal technique after aortic cusp ablation have not previously been reported. ⋯ Ablation of VA within the aortic cusps is safe and effective in long‑ term follow up. The ZF approach is feasible, although it requires greater expertise and more imaging modalities.

Multicenter StudyAssociation of intrarenal blood flow with renal function and target organ damage in hypertensive patients with fibromuscular dysplasia: the ARCADIA-POL study.
INTRODUCTION Data on the assessment of intrarenal blood flow parameters in patients with renal fibromuscular dysplasia (FMD) are scarce. OBJECTIVES The aim of the study was to evaluate intrarenal blood flow parameters in patients with FMD and significant or nonsignificant renal artery stenosis (RAS). PATIENTS AND METHODS We evaluated intrarenal blood flow parameters by Doppler ultrasonography in 153 patients with renal FMD enrolled in the ARCADIA‑POL study: 32 and 121 patients with and without significant RAS, respectively, compared with 60 matched patients with essential hypertension and 60 healthy controls. ⋯ In patients with significant RAS, there was a significant correlation between RRI and known duration time of hypertension, left ventricular diastolic function, and age. In a separate, "per‑kidney" analysis, renal arteries with FMD and significant RAS were characterized by lower RRI values, higher maximal blood flow velocity, higher renal aortic ratio, and longer acceleration time compared with renal arteries with FMD and nonsignificant RAS as well as renal arteries without FMD. CONCLUSIONS In contrast to atherosclerotic RAS, intrarenal blood flow in patients with FMD and RAS is preserved, confirming that renal vasculature is relatively intact in these patients.

Multicenter Study Observational StudyRelationship between infarct artery location, acute total coronary occlusion, and mortality in STEMI and NSTEMI patients.
The prevalence of total coronary occlusion of an infarct‑related artery (IRA) and its impact on the outcome can differ between patients with non‑ST‑elevation myocardial infarction (NSTEMI) and those with ST‑segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). ⋯ Totally occluded IRA (TIMI flow grade 0) on baseline angiogram was not associated with higher 36‑month mortality rates after both NSTEMI and STEMI treated with PCI in comparison with patients with patent IRA except for totally occluded LAD in STEMI.
