[Ab] Abstract:Pulmonary arterial hypertension (PAH) is a progressive disorder characterized by remodeling of the pulmonary vasculature and a rise in right ventricular (RV) afterload. The increased RV afterload leads to right ventricular failure (RVF) which is the reason for the high morbidity and mortality in PAH patients. The objective was to evaluate the therapeutic efficacy and antiremodeling potential of the phosphodiesterase type 5 (PDE5) inhibitor sildenafil and the soluble guanylate cyclase stimulator riociguat in a model of pressure overload RV hypertrophy induced by pulmonary artery banding (PAB). Mice subjected to PAB, one week after surgery, were treated with either sildenafil (100 mg/kg/d, = 5), riociguat (30 mg/kg/d, = 5), or vehicle ( = 5) for 14 days. RV function and remodeling were assessed by right heart catheterization, magnetic resonance imaging (MRI), and histomorphometry. Both sildenafil and riociguat prevented the deterioration of RV function, as determined by a decrease in RV dilation and restoration of the RV ejection fraction (EF). Although both compounds did not decrease right heart mass and cellular hypertrophy, riociguat prevented RV fibrosis induced by PAB. Both compounds diminished TGF-beta1 induced collagen synthesis of RV cardiac fibroblasts . Treatment with either riociguat or sildenafil prevented the progression of pressure overload-induced RVF, representing a novel therapeutic approach.

[Ab] Abstract:An 18-month-old male Akita Inu dog developed fever and lameness 8 months after successful transcatheter closure of a patent ductus arteriosus with an Amplatz Canine Duct Occluder (ACDO). Corynebacterium species were cultured from 3 blood samples. Echocardiography showed a vegetative process on the aortic valves. The dog died spontaneously 3 days after development of the initial signs. Necropsy confirmed the presence of bacterial ductal arteritis and myocarditis, and revealed an incomplete endothelialization of the intraductal metal implant. The reason for the lack of (neo)endothelialization of the ACDO remains unknown. We conclude that late-onset bacterial device-related ductal arteritis can develop in dogs where the implant is incompletely covered by a protective endothelial layer.

[Ab] Abstract:INTRODUCTION: Bioresorbable coronary scaffolds (BRS) have been developed to increase the late safety of coronary angioplasty by providing transitory coronary support and then being fully incorporated to the vessel wall. In the present trial, we sought to evaluate the performance and changes over time in the DESolve™ novolimus-eluting BRS using serial intravascular ultrasound (IVUS) in patients submitted to percutaneous coronary interventions. METHODS: Single-center, prospective, non-randomized study involving 17 consecutive patients submitted to implantation of the DESolve™ scaffold and serial evaluated with IVUS at different time points (post procedure, 6 and 18 months). Primary endpoint included the variation in lumen, scaffold, and vessel diameter and area along the months. RESULTS: Angiographic success was achieved in all cases. Scaffold area and volume on IVUS were significantly greater at 6 months than at baseline (6.41 ± 1.35 mm vs. 7.35 ± 1.53 mm , P < 0.002; and 101.19 ± 20.9 mm vs. 118.51 ± 26.6 mm , P = 0.001). Late lumen loss was 0.22 ± 0.30 mm at 6 months and 0.33 ± 0.44 mm at 18 months. No major adverse cardiac events occurred. At late follow-up (18 months) the scaffold was not visualized by IVUS; therefore the evaluation was restricted to lumen and vessel at that time point. CONCLUSIONS: IVUS serial evaluation of the novel DESolve BRS showed an increase in the device dimensions between baseline and 6 months, with concomitant enlargement of lumen dimensions and effective suppression of neointimal proliferation. At 18 months, no footprint of the scaffold was detected and the initial lumen enlargement was sustained.

[Ab] Abstract:The feasibility, safety, and high technical success of robotically assisted percutaneous coronary intervention (PCI) for the treatment of both simple and complex coronary disease has been demonstrated. As the current generation robotic platform is limited to a rapid exchange system, orbital or rotational atherectomy cannot be performed robotically. However, excimer laser coronary atherectomy is performed with a rapid exchange catheter but its feasibility during robotically assisted PCI is unknown. We report the successful use of laser atherectomy during two complex robotically assisted PCI procedures using the CorPath GRX robotic system.

[Ti] Title:Novel method for radial sheath removal using manual pressure over hemostatic pad combined with ulnar compression.

[Ab] Abstract:OBJECTIVES: Study a novel method using manual pressure on a hemostatic pad and hemoband for ulnar compression as a potential alternative for radial sheath removal. BACKGROUND: The standard for transradial access site (TRA) sheath removal requires an inflatable pressure band over the radial artery and recently a band over the ulnar artery to reduce complications. We present a novel technique using a SoftSeal®-STF hemostatic pad over the radial artery combined with a hemoband over the ulnar artery after sheath removal. METHODS: All patients had activated clotting time (ACT); sheath removal was performed immediately upon transfer to the recovery room. A hemoband compressed the ulnar artery, radial artery flow was measured using plethysmography and pulse oximetry while direct pressure applied using SoftSeal-STF hemostatic pad for 15 min after radial sheath removed. Radial artery patency was measured using reverse Barbeau test. If radial artery occlusion (RAO) present, patient was asked to return in one month to repeat test. RESULTS: Fifty-nine patients were enrolled in the study, one-third with diabetes mellitus, one-third with prior coronary artery bypass surgery, and one-third with history of percutaneous coronary intervention. Mean ACT 261 ± 50 sec, all patients had 4 Fr sheaths and no PCI were performed. Three (6%) patients had minor bleeding requiring use of a pressure band and one (2%) had RAO, which re-canalized at one month. CONCLUSIONS: Manual pressure of SoftSeal-STF hemostatic pad combined with ulnar compression is a potential alternative to current practice with an inflatable pressure band.

[Ti] Title:Anomalous coronary artery originating from the opposite sinus of Valsalva (ACAOS), fractional flow reserve- and intravascular ultrasound-guided management in adult patients.

[Ab] Abstract:OBJECTIVES: To describe the use of fractional flow reserve (FFR) and intravascular ultrasound (IVUS) in the evaluation of patients with anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS). BACKGROUND: ACAOS of the right and left coronary are rare, but may lead to symptoms and impose a risk for sudden cardiac death, depending on several anatomical features. Assessment and risk estimation is challenging in (nonathlete) adults, especially if they present without symptoms or with atypical complaints. METHODS: The team retrospectively studied 30 consecutive patients with ACAOS with interarterial course, who received IVUS- and FFR-guided treatment at our institution between October 2010 and September 2017. RESULTS: FFR was abnormal in only seven patients. IVUS showed the typical slit-like anatomy of the orifice in 23 patients. Based on FFR and/or IVUS results, in conjunction with the clinical presentation, clinical decision was made. A decision for intervention was made if at least two out of three entities were abnormal. Intervention implied unroofing of the coronary artery (n = 10) or coronary artery bypass grafting (n = 1). In all other patients a conservative strategy was followed. No adverse events occurred in the total population after a median of 37 (0-62) months of follow-up. CONCLUSIONS: Conservative treatment may be justifiable in adult patients with ACAOS in the presence of normal FFR and nonsuspicious symptoms, despite the presence of an interarterial course and/or slitlike orifice on IVUS. We recommend the use of FFR and IVUS in the standard work-up for adult patients with ACAOS and propose the use of a flowchart to aid in decision-making.

[La] Language:eng
[Ab] Abstract:Percutaneous coronary intervention (PCI) of mammary artery bypass grafts through a trans-radial (TR) approach can present unique challenges, including coaxial vessel engagement of the guiding catheter, adequate visualization of the target lesion, sufficient backup support for equipment delivery, and the ability to reach very distal lesions. The GuideLiner catheter, a rapid exchange monorail mother-in-daughter system, facilitates successful interventions in such challenging anatomy. We present a case of a patient undergoing PCI of a right internal mammary artery (RIMA) graft via TR access in whom the graft could not be engaged with any guiding catheter. Using a balloon tracking technique over a guidewire, a GuideLiner was placed as an extension of the guiding catheter and facilitated TR-PCI by overcoming technical challenges associated with difficult anatomy.

[Ab] Abstract:OBJECTIVE: To examine the impact of re-entry device (RED) use on 1- and 5-year outcomes after endovascular treatment of common iliac artery (CIA) chronic total Occlusions (CTOs). BACKGROUND: There are not enough data regarding the long-term safety and efficacy of RED. METHODS: We performed a two-center retrospective study of 115 patients (140 lesions) undergoing CIA CTO endovascular intervention between 2006 and 2016. Baseline characteristics and long-term outcomes were described. A Cox proportional hazard model was developed to determine if REDs were associated with target lesion revascularization (TLR) or major adverse limb events (MALE) after 1 and 5 years. RESULTS: Among 140 lesions, 43 (31%) required use of a RED. The mean age was 63.9 years and the majority (n = 80) of patients were male. An antegrade crossing approach and treatment of restenotic lesions were less common in the RED group (10% vs. 29%, P < .05 and 0% vs. 21%, P < .05, respectively). There were no significant differences in Rutherford class, pre-procedure ABI, or patient presentation. The procedural complication rates were similar between the two groups. The 1- and 5-year TLR rates for lesions treated with re-entry device vs. standard approaches were 11% vs. 9%; P = 0.8 and 29% vs. 29%; P = 0.9 respectively. The 1 and 5-year MALE rates for lesions treated with re-entry device were 5% vs. 6%; P = 0.8 and 11% vs. 11%; P = 0.9 respectively. CONCLUSIONS: This retrospective analysis found that recanalization of CIA occlusions using a RED is safe and is associated with long-term clinical outcomes similar to that of standard crossing techniques.

[Ab] Abstract:BACKGROUND: Evolut-R 34 mm (received CE mark in January 2017) and Sapien-3 29 mm are the only options for transcatheter aortic valve replacement (TAVR) in patients with annulus ≥26 mm. We compared the short-term outcomes of these valves in these patients. METHODS: Data was collected prospectively from consecutive patients with severe aortic stenosis and annulus diameter larger than 26 mm treated by femoral approach TAVR. RESULTS: Between February 1, 2014 to August 19, 2017 Sapien-3 29 mm was implanted in 55 and Evolut-R 34 mm in 37 consecutive patients. Device success rate was 98.2% and 97.3% (P = 1.0) and the composite peri-procedural complication rate was 7.3% and 2.7% (P = .645) in Sapin-3 29 mm and Evolut-R 34 mm, respectively. Composite endpoint of early safety in-hospital did not differ significantly [5(9.2%) vs 3(8.1%), P = 1.00], respectively. Prosthetic valve Gradients were significantly lower with Evolut-R 34 mm [maximal (18.0 ± 5.8 vs 11.2 ± 4.8 mmHg, P < .001) and mean (10.0 ± 3.3 vs 6.3 ± 2.7 mmHg, P < .001)]. Pacemaker implantation rate was high in both groups, and numerically but not statistically significant higher with Evolut-R [10/50 (20.0%) vs 8/28 (28.6%), P = .389]. CONCLUSIONS: As compared to Sapien-3 29 mm the Evolut-R 34 mm is a real alternative for TAVR in patients with a large annulus with a comparable peri-procedural complication rate, better hemodynamic results but a trend for higher pacemaker rate.
