Impact of moderate or severe left ventricular outflow tract calcification on clinical outcomes of patients with severe aortic stenosis undergoing transcatheter aortic valve implantation with self- and balloon-expandable valves: a post hoc analysis from the SOLVE-TAVI trial.

Background: Left ventricular outflow tract (LVOT) calcification has been associated with worse outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) and may influence the selection of prosthetic valve type.

Aims: We aimed to evaluate the impact of LVOT calcification on outcomes after TAVI with a self-expanding valve (SEV) versus a balloon-expandable valve (BEV).

Methods: Patients of the SOLVE-TAVI trial, randomised to Edwards SAPIEN 3 or Medtronic Evolut R, were divided according to LVOT calcification into no/mild (≤1 calcium nodule extending <5 mm and covering <10% of the LVOT perimeter) and moderate/severe LVOT calcification groups.

Impact of implantation depth on outcomes of new-generation balloon-expandable transcatheter heart valves.

Background: Little is known about the impact of the ID on outcomes and device success using balloon-expandable devices. This study sought to analyze the impact of implantation depth (ID) on procedural outcomes.

Methods: In consecutive patients (n = 969) undergoing transfemoral TAVR with new-generation balloon-expandable prostheses, the mean ID (ID) was determined by aortography and categorized into low, correct, and high device position.

Impact of Anesthesia Strategy and Valve Type on Clinical Outcomes After Transcatheter Aortic Valve Replacement.

Background: The randomized SOLVE-TAVI (compariSon of secOnd-generation seLf-expandable vs. balloon-expandable Valves and gEneral vs. local anesthesia in Transcatheter Aortic Valve Implantation) trial compared newer-generation self-expanding valves (SEV) and balloon-expandable valves (BEV) as well as local anesthesia with conscious sedation (CS) and general anesthesia (GA) in patients undergoing transfemoral transcatheter aortic valve replacement (TAVR).

General Versus Local Anesthesia With Conscious Sedation in Transcatheter Aortic Valve Implantation: The Randomized SOLVE-TAVI Trial.

Background: In clinical practice, local anesthesia with conscious sedation (CS) is performed in roughly 50% of patients undergoing transcatheter aortic valve replacement. However, no randomized data assessing the safety and efficacy of CS versus general anesthesia (GA) are available.

Methods: The SOLVE-TAVI (Comparison of Second-Generation Self-Expandable Versus Balloon-Expandable Valves and General Versus Local Anesthesia in Transcatheter Aortic Valve Implantation) trial is a multicenter, open-label, 2×2 factorial, randomized trial of 447 patients with aortic stenosis undergoing transfemoral transcatheter aortic valve replacement comparing CS versus GA.

Comparison of newer generation self-expandable vs. balloon-expandable valves in transcatheter aortic valve implantation: the randomized SOLVE-TAVI trial.

Aims: Transcatheter aortic valve implantation (TAVI) has emerged as established treatment option in patients with symptomatic aortic stenosis. Technical developments in valve design have addressed previous limitations such as suboptimal deployment, conduction disturbances, and paravalvular leakage. However, there are only limited data available for the comparison of newer generation self-expandable valve (SEV) and balloon-expandable valve (BEV).

OCT-assessment of scaffold resorption: Analysis of strut intensity by a new resorption index for poly-l-lactic acid bioresorbable vascular scaffolds.

Background: The aim of this study was to analyze individual differences in resorption of bioresorbable vascular scaffolds (BRS) through optical coherence tomography (OCT) analysis and to identify factors potentially influencing the resorption process.

Methods: Between April 2016 and July 2017 clinically driven invasive coronary angiography and OCT examinations were performed in 36 patients who had previously been treated with a total of 48 BRS (ABSORB BVS, Abbott Vascular, Santa Clara, CA). For each scaffold, a new BRS-RESORB-INDEX (BRI) was calculated.

Barostim Implantation with Ipsilateral Carotid Endarterectomy as a One-Stage Procedure.

Clinical trials have demonstrated significant and lasting reductions in arterial pressure from baroreflex activation therapy (BAT), resulting from electrical stimulation of the carotid sinus in patients with resistant arterial hypertension. Significant carotid atherosclerosis, however, has been a contraindication for ipsilateral implantation due to a potentially increased risk of periprocedural stroke and uncertain antihypertensive efficacy. Here, we describe the first case in which BAT was applied safely and effectively in a patient with distinct cerebral arteriosclerosis after ipsilateral carotid endarterectomy as a one-stage procedure without neurologic complications.

Neutrophil gelatinase-associated lipocalin (NGAL) for the early detection of contrast-induced nephropathy after percutaneous coronary intervention.

Background: Contrast-induced acute kidney injury (CI-AKI) occurs in up to 13% of patients undergoing percutaneous coronary intervention (PCI). Neutrophil gelatinase-associated lipocalin (NGAL) is an early biomarker for renal impairment. We investigated whether increased urinary NGAL concentrations were predictive of CI-AKI within 2 days after PCI or of a higher re-hospitalization rate within 9 months.

Bauhinia bauhinioides cruzipain inhibitor reduces endothelial proliferation and induces an increase of the intracellular Ca2+ concentration.

Proteinase inhibitors, isolated from different types of Bauhinia, have an effect on apoptosis, angiogenesis and inflammation. The Bauhinia bauhinioides cruzipain inhibitor (BbCI) is a Kunitz-type inhibitor and inactivates the cysteine proteinases cruzipain and cruzain from Trypanosoma cruzi. Cruzipain and tissue kallikrein have similar biochemical properties, e.

Randomized comparison of multipolar, duty-cycled, bipolar-unipolar radiofrequency versus conventional catheter ablation for treatment of common atrial flutter.

Introduction: Radiofrequency (RF) catheter ablation has been established as an effective and curative treatment for atrial flutter (AFL). Approved methods include a drag-and-drop method, as well as a point-by-point ablation technique. The aim of this study was to compare the acute efficacy and procedural efficiency of a multipolar linear ablation catheter with simultaneous energy delivery to multiple catheter electrodes against conventional RF for treatment of AFL.
