Left atrial appendage (LAA) closure for stroke prevention in the setting of non valvular atrial fibrillation is an alternative to oral anticoagulation in patients with increased bleeding risk. It allows similar reduction in thromboembolic events, in particular stroke, compared to warfarin. A common clinical dilemma is the management of patients with peri-device leak after LAA occlusion. This has been documented in both percutaneous as well as with surgical approaches. The specific definitions of leak severity, and the longer term clinical implications are poorly understood...

AIMS: In the minimalist transcatheter aortic valve implantation (TAVI) era, the usage of transesophageal echocardiography becomes restricted. Conversely, aortography gains clinical ground in quantifying prosthetic valve regurgitation (PVR) during the procedure. In a mock circulation system, we sought to compare the contrast volume required and the accuracy of aortographic videodensitometric PVR assessment using a synchronized diastolic and standard (non-synchronized) injection aortography...

AIMS: In addition to patients with pure/predominant aortic stenosis (PAS), real-world transcatheter aortic valve implantation (TAVI) referrals include patients with mixed aortic valve disease (MAVD; severe stenosis + moderate-severe regurgitation). We sought to compare TAVI outcomes in patients with MAVD vs. PAS. METHODS AND RESULTS: Out of 793 consecutive patients undergoing TAVI, 106 (13.4%) had MAVD. Patients with MAVD were younger and had a higher operative risk, a severer adverse cardiac remodeling, and a worse functional status than patients with PAS...

AIMS: Patients with degraded bioprosthetic heart valves (BHV) who are not candidates for valve replacement may benefit from transcatheter valve-in-valve (VIV) therapy. However, at smaller sized surgical BHV the resultant orifice may become too narrow. To overcome this, the valve frame can be fractured by a high-pressure balloon prior to VIV. However, knowledge on fracture pressures and mechanics are prerequisites. The aim of this study is to identify the fracture pressures needed in BHV, and to describe the fracture mechanics...

AIMS: Transcatheter valve-in-valve (VIV) implantation in small surgical tissue valves is challenged by the problem of residual stenosis. We report our first ten cases of fracturing small dysfunctional Mitroflow bioprostheses by high-pressure balloon dilatation to increase the internal diameter of the surgical valve before VIV (BF-VIV). METHODS AND RESULTS: BF-VIV was performed in 10 patients (mean age 84±4 years) with failing Mitroflow valves size 19 mm (n=3, threshold of fracture 15 atm) and 21 mm (n=7, threshold of fracture 13 atm)...

AIMS: There are limited data on the prognosis of deferred non-culprit lesions in patients with acute coronary syndrome (ACS) based on fractional flow reserve (FFR). We investigated the prognosis of deferred non-culprit lesions in ACS patients, compared with deferred lesions in patients with stable coronary artery disease (SCAD), on the basis of FFR. METHODS AND RESULTS: The clinical outcomes of 449 non-culprit lesions (301 patients with ACS) were compared with 2,484 lesions (1,295 patients with SCAD) in which revascularization was deferred on the basis of a high FFR (>0...

AIMS: To compare the mid-term clinical outcomes of patients treated with everolimus-eluting bioresorbable scaffold (BVS) versus everolimus-eluting metallic stent (EES) for percutaneous coronary intervention. METHODS AND RESULTS: We performed a meta-analysis of aggregate data by searching Medline, EMBASE, Cochrane databases and proceedings of international meetings for randomized trials reporting the clinical outcomes beyond 1 year of patients treated with BVS versus EES...

AIMS: Device sizing for LAA closure using transesophageal echocardiography (TEE) can be challenging due to complex LAA anatomy. We investigated whether the use of 3D-printed left atrial appendage (LAA) models based on pre-procedural computed tomography (CT) permits accurate device sizing. METHODS AND RESULTS: 22 patients (73±8 years, 55% male) with atrial fibrillation requiring anticoagulation at high bleeding risk underwent LAA closure (WatchmanTM device). Pre-procedurally, LAA was sized by TEE and third-generation dual-source CT...

AIMS: The age-thrombus score-index of microcirculatory resistance (ATI) score is a diagnostic tool able to predict suboptimal myocardial reperfusion before stenting, in patients with ST elevation myocardial infarction (STEMI). We aimed to validate the ATI score against cardiac magnetic resonance imaging (cMRI). METHODS AND RESULTS: The ATI score was calculated prospectively in 80 STEMI patients. cMRI was performed within 48 hours in all patients and in 50 patients at six months follow up to assess the extent of infarct size (IS%) and microvascular obstruction (MVO%)...

AIMS: To assess in vitro the diagnostic accuracy of computed tomography angiography (CTA) for the evaluation of complex coronary lesions. METHODS AND RESULTS: Five Plexiglas phantoms with three bifurcations lesions each were designed to mimic the anatomic variations and fractal phenomenon of the coronary tree. In addition, luminal stenosis were scaled up with increases of 10%. A third generation dual-source computed tomography was used. Automated quantitative CTA analysis was performed...

AIMS: To assess clinical restenosis and its predictors after implantation bioresorbable vascular scaffolds (BVS) in everyday practice in the large scale German-Austrian ABSORB Registry (GABI-R). METHODS AND RESULTS: Between November 2013 and January 2016, 3264 patients underwent BVS implantion in 93 centers of GABI-R. At 6-month follow-up, 24 patients experienced clinically-indicated target lesion revascularization (cTLR) unrelated to BVS thrombosis (cumulative incidence 0...

AIMS: Video-motion analysis (VMA) uses fluoroscopic sequences to derive on catheter and guide-wire movement, and is able to calculate 2D catheter-tip path-length (PL) on the basis of frame-by-frame pixel coordinates. The objective of this study was to validate VMA in coronary angiography as a method of skill assessment. METHODS AND RESULTS: 47 coronary interventions performed by 10 low- (<1000 cases; group A), 5 medium- (1000-4000; group B) and 6 high- (>4000; group C) experience- volume cardiologists were prospectively recorded and analysed using this software...

AIMS: To develop a formula enabling the quantification of aortic valve calcification (AVC) on contrast-enhanced CT of patients undergoing transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: 217 consecutive patients with severe aortic valve stenosis undergoing non-enhanced (NECT) and contrast-enhanced electrocardiography-gated CT angiography (CECT) prior to TAVI were subdivided into a training (n=145) and validation cohort (n=72). AVC was semi-automatically segmented on CECT (AVCCE)...

AIMS: Fractional flow reserve (FFR) estimated from coronary computed tomography angiography (CT-FFR) offers non-invasive detection of lesion-specific ischemia. We developed and validated a fast CT-FFR algorithm utilizing the Lattice-Boltzmann Method for blood flow simulation (LBM CT-FFR). METHODS AND RESULTS: 64 patients from 3 institutions with clinically-indicated CTA and invasive FFR measurement were retrospectively analyzed. CT-FFR was performed using an on-site tool interfacing with a commercial Lattice-Boltzmann fluid dynamics cloud-based platform...

AIMS: Endovascular thrombectomy (EVT) improves outcome after acute ischemic stroke (AIS) caused by an intracranial occlusion. The aim of the present study is to determine if atrial fibrillation (AF) modifies the effect of EVT. METHODS AND RESULTS: MRCLEAN was a randomized clinical trial of EVT plus usual care vs. usual care alone for patients with an intracranial occlusion. The primary outcome was the modified Rankin scale (mRS) score at 90 days. The primary effect parameter was the adjusted common odds ratio (acOR), estimated with ordinal logistic regression and adjusted for age and stroke severity at baseline...
