Abstract
The aim of this case study was to investigate the effects of an 8-wk combined exercise intervention, consisting of visual-coordinative and high-intensity interval training (HIIT), on the physical and visuomotor-functional capacity, performance, and physiological profile of a moderately active 29-yr-old man diagnosed with choroidal melanoma of the left eye. Data were collected on three occasions: at the initial diagnosis (T0), after hospitalization and radiotherapy treatment (T1), and following the recovery through the exercise intervention (T2), spanning a total of 17 wk. The primary outcome variables consisted of visuomotor and functional tests (VFTs), cardiorespiratory fitness (CRF), and microvascular circulation measured via flicker light-induced dilation (FiD). For visuomotor tests in general, a significant decline was observed between baseline T0 and T1 (by 6%-22%), followed by significant improvements at T2 (by 11%-36%), surpassing the initially observed T0 values. The cardiopulmonary exercise testing (CPET)-derived parameters exhibited a similar pattern, declining from T0 to T1 [by 8%-12% for peak V̇o2, peak power output (PO), and CPET duration, respectively], with a subsequent recovery observed in response to 8 wk of exercise training (T2), resulting in increases of 11%-25% for V̇o2, peak PO, and CPET duration. Interestingly, the dilation of both arteries and veins in response to the FiD stimulus exhibited a twofold increase compared with baseline levels. Our results suggest that the 8-wk exercise intervention improved patients' VFT and CRF profiles and exceeded baseline values. Additional investigation, particularly through randomized controlled trials, is needed to comprehensively explain changes in FiD.NEW & NOTEWORTHY Results presented here suggest that combined visual-coordinative and HIIT training improves the visual-functional capacity, performance, and physiological profile of choroidal melanoma patients during treatment recovery. This case study lays the groundwork for further research concerning exercise therapy in this unique patient population. In addition, further investigation is required to fully comprehend the combined effects of exercise and radiation therapy on vasculature and oxygenation in patients with choroidal melanoma.

Abstract
PURPOSE Evaluate optic nerve sheath and pial diameters (ONSD, ONPD) via sonography and computed tomography (CT) after out-of-hospital cardiac arrest (CA) and to compare their prognostic significance with other imaging and laboratory biomarkers. MATERIALS AND METHODS A prospective observational study enrolling patients after successful resuscitation between December 2017 and August 2021. ONSD and ONPD were measured with sonography. Additionally, ONSD, and also grey-to-white ratio at basal ganglia (GWRBG) and cerebrum (GWRCBR), were assessed using CT. Lactate and neuron specific enolase (NSE) blood levels were measured. RESULTS Sonographically measured ONSD and ONPD yielded no significant difference between survival and non-survival (p values ≥0.4). Meanwhile, CT assessed ONSD, GWRBG, GWRCBR, and NSE levels significantly differed regarding both, survival (p values ≤0.005) and neurological outcome groups (p values ≤0.04). For survival prognosis, GWRBG, GWRCBR, and NSE levels appeared as excellent predictors; in predicting a good neurological outcome, NSE had the highest accuracy. CONCLUSIONS CT diagnostics, in particular GWRBG and GWRCBR, as well as NSE as laboratory biomarker, appear as excellent outcome predictors. Meanwhile, our data lead us to recommend caution in utilizing sonography assessed ONSD and ONPD for prognostic decision-making post-CA.

Abstract
BACKGROUND We previously reported procedural and 30-day outcomes of a German early multicenter experience with the PASCAL system for severe mitral regurgitation (MR). This study reports 1-year outcomes of mitral valve transcatheter edge-to-edge repair with the PASCAL system according to MR etiology in a large all-comer cohort. METHODS AND RESULTS Clinical and echocardiographic outcomes up to 1-year were investigated according to MR etiology (degenerative [DMR], functional [FMR], or mixed [MMR]) in the first 282 patients with symptomatic MR 3+/4+ treated with the PASCAL implant at 9 centers in 2019. A total of 282 patients were included (33% DMR, 50% FMR, 17% MMR). At discharge, MR reduction to ≤1+/2+ was achieved in 58%/87% of DMR, in 75%/97% of FMR, and in 78%/98% of patients with MMR (P=0.004). MR reduction to ≤1+/2+ was sustained at 30 days (50%/83% DMR, 67%/97% FMR, 74%/100% MMR) and at 1 year (53%/78% DMR, 75%/97% FMR, 67%/91% MMR) with significant differences between etiologies. DMR patients with residual MR 3+/4+ at 1-year had at least complex valve morphology in 91.7%. Valve-related reintervention was performed in 7.4% DMR, 0.7% FMR, and 0.0% MMR (P=0.010). At 1-year, New York Heart Association Functional Class was significantly improved irrespective of MR etiology (P<0.001). CONCLUSIONS In this large all-comer cohort, mitral valve transcatheter edge-to-edge repair with the PASCAL system was associated with an acute and sustained MR reduction at 1-year in all causes. However, in patients with DMR, MR reduction was less pronounced, reflecting the high incidence of complex or very complex anatomies being referred for mitral valve transcatheter edge-to-edge repair.

Abstract
Background Previous trials investigating antithrombotic therapy with a direct oral anticoagulant (DOAC) and a P2Y12 inhibitor after percutaneous coronary intervention (PCI), termed dual therapy, allowed a short period of triple therapy including a DOAC, a P2Y12 inhibitor, and aspirin. Aims This study aimed to determine whether discontinuation of aspirin on the first post-procedural day is safe or causes ischemic events. Methods Ischemic and bleeding events during hospitalization were investigated retrospectively in all patients treated with dual therapy (DOAC + P2Y12 inhibitor, designated as group 1) or triple therapy (DOAC + P2Y12 inhibitor+aspirin, designated as group 2) from day 1 after PCI at our center. Results Of 4,564 consecutive PCI procedures, 1,059 (23.2%) had an indication for OAC. Of these, 322 met the inclusion criteria for group 1 and 62 for group 2. Baseline characteristics, CHA2DS2-VASc and HAS-BLED scores showed no relevant differences between the two groups, and the main indication for DOAC therapy was atrial fibrillation in both groups. Approximately ¼ of patients were treated for acute coronary syndrome. The mean length of post-procedural hospitalization was 2.1 ± 2.5 and 2.2 ± 3.0 days in group 1 and 2, respectively (p = 0.305). One patient per group suffered a TIA (p = 0.297). There were no other ischemic events and no statistically significant differences in bleeding events. A subgroup analysis of cases hospitalized for ≥2 post-procedural days (group 1: 100 cases, mean 4.4 ± 3.4 days vs. group 2: 25 cases, mean 4.0 ± 4.1 days) confirmed these results. Conclusion The initiation of dual therapy and thus discontinuation of aspirin on the first postprocedural day appears to be safe with respect to short-term ischemic events in a real-world population. Almost ¼ of patients undergoing PCI have an indication for OAC, highlighting the relevance of this issue.

Abstract
OBJECTIVE To compare the measurement of aortic diameters using a novel flow-independent MR-Angiography (3D modified Relaxation-Enhanced Angiography without Contrast and Triggering (modified REACT)) and transthoracic echocardiography (TTE) in Marfan syndrome (MFS) patients. MATERIAL AND METHODS This retrospective, single-center analysis included 46 examinations of 32 MFS patients (mean age 37.5 ± 11.3 years, 17 women, no prior aortic surgery) who received TTE and 3D modified REACT (ECG- and respiratory-triggering, Compressed SENSE factor 9 for acceleration of image acquisition) of the thoracic aorta. Aortic diameters (sinus of Valsalva (SV), sinotubular junction (STJ), and ascending aorta (AoA)) were independently measured by two cardiologists in TTE (leading-edge) and two radiologists in modified REACT (inner-edge, using multiplanar reconstruction). Intraclass correlation coefficient, Bland-Altman analyses, and Pearson's correlation (r) were used to assess agreement between observers and methods. RESULTS Interobserver correlation at the SV, STJ, and AoA were excellent for both, TTE (ICC = 0.95-0.98) and modified REACT (ICC = 0.99-1.00). There was no significant difference between TTE and modified REACT for diameters measured at the SV (39.24 ± 3.24 mm vs. 39.63 ± 3.76 mm; p = 0.26; r = 0.78) and the STJ (35.16 ± 4.47 mm vs. 35.37 ± 4.74 mm; p = 0.552; r = 0.87). AoA diameters determined by TTE were larger than in modified REACT (34.29 ± 5.31 mm vs. 30.65 ± 5.64 mm; p < 0.01; r = 0.74). The mean scan time of modified REACT was 05:06 min ± 02:47 min, depending on the patient's breathing frequency and heart rate. CONCLUSIONS Both TTE and modified REACT showed a strong correlation for all aortic levels; however, at the AoA, diameters were larger using TTE, mostly due to the limited field of view of the latter with measurements being closer to the aortic valve. Given the excellent interobserver correlation and the strong agreement with TTE, modified REACT represents an attractive method to depict the thoracic aorta in MFS patients.

Abstract
Vascular diseases like atherosclerosis and abdominal aortic aneurysm (AAA) are common pathologies in the western world, promoting various potentially fatal conditions. Here, we evaluate high-resolution (HR) ultrasound in mouse models of atherosclerosis and AAA as a useful tool for noninvasive monitoring of early vascular changes in vivo. We used Apolipoprotein E-deficient (ApoE-/-) mice as an atherosclerosis model and induced AAA development by the implementation of Angiotensin II-releasing osmotic minipumps. HR ultrasound of the carotid artery or the abdominal aorta was performed to monitor vascular remodeling in vivo. Images were analyzed by speckle tracking algorithms and correlated to histological analyses and subsequent automated collagen quantification. Consistent changes were observed via ultrasound in both models: Global radial strain (GRS) was notably reduced in the AAA model (23.8 ± 2.8% vs. 12.5 ± 2.5%, p = 0.01) and in the atherosclerotic mice (20.6 ± 1.3% vs. 15.8 ± 0.9%, p = 0.02). In mice with AAA, vessel distensibility was significantly reduced, whereas intima-media thickness was increased in atherosclerotic mice. The area and collagen content of the tunica media were increased in diseased arteries of both models as measured by automated image analysis of Picrosirius Red-stained aortic sections. Correlation analysis revealed a strong correlation of multiple parameters, predicting early vascular damage in HR ultrasound and histological examinations. In conclusion, our findings underscore the potential of HR ultrasound in effectively tracing early alterations in arterial wall properties in murine models of atherosclerosis and AAA.

Abstract
Myocardial infarction (MI) is a leading cause of morbidity and mortality worldwide. Improved survival has led to an increasing incidence of ischemic cardiomyopathy, making it a major reason for hospitalization in the western world. The inflammatory response in the ischemic myocardium determines the extent of structural remodeling and functional deterioration, with neutrophils (PMN) being a key modulator of the propagation and resolution of inflammation. The heme enzyme myeloperoxidase (MPO) is abundantly expressed in PMN and is an important mediator of their inflammatory capacities. Here, we examine the effects of PMN reduction, MPO deficiency and MPO inhibition in two murine models of MI. Reduction in PMN count resulted in less scar formation and improved cardiac function. Similar results were obtained in genetically MPO deficient mice, suggesting that MPO is a critical factor in PMN-mediated cardiac remodeling. To test our findings in a therapeutic approach, we orally administered the MPO inhibitor AZM198 in the context of MI and could demonstrate improved cardiac function and reduced structural remodeling. Therefore, MPO appears to be a favorable pharmacological target for the prevention of long-term morbidity after MI.

Abstract
OBJECTIVE The objective of this study was to investigate the long-term outcome after open repair of inflammatory infrarenal aortic aneurysms. METHODS A total of 62 patients (mean age, 68.9 ± 8.8 years; 91.9% male) undergoing open surgery for inflammatory aortic aneurysm from 1995 until 2014 in a high-volume vascular center were retrospectively evaluated. The patients' demographics, preoperative and postoperative clinical characteristics, imaging measurements, and procedural data were collected. Study end points were preoperative and postoperative sac diameter, evolution of periaortic fibrosis and development of hydroureteronephrosis detected by computed tomography (CT) scan, and mortality and morbidity after 30 days and at the time of maximum follow-up. RESULTS The mean abdominal aortic aneurysm diameter was 67.3 ± 16.7 mm. A total of 30 patients (48.4%) were asymptomatic, 27 patients (43.5%) were symptomatic, and 5 patients (8.1%) were treated for ruptured aneurysm. In 25 patients (40.3%), an aorta-aortic tube graft was implanted; in 37 patients (59.7%), an aortic bifurcation graft was used. Median operating time was 208 minutes (range, 83-519 minutes). Median aortic clamping time was 31 minutes (range, 14-90 minutes); in 25 patients (40.3%), suprarenal aortic cross-clamping was necessary. Hydroureteronephrosis was preoperatively diagnosed by CT scan in 16 patients (25.8%), with the need for a ureteral stent in 11 patients (17.7%). Aneurysm- and procedure-associated 30-day mortality was 11.3% (n = 7), with septic multiple organ failure in four patients and cardiac arrest in three patients. The overall perioperative complication rate was 33.9% (n = 21 patients). Median follow-up was 71.0 months (range, 0.2-231.6 months). At 1 year, 2 years, 4 years, and 6 years, overall survival was 83.4%, 79.6%, 79.6%, and 72.6%, respectively. Six patients (9.7%) required a reintervention during follow-up, predominantly aneurysm related and caused by aortoenteric fistula and graft infection (three of five patients). Median maximum thickness of preoperative perianeurysmal inflammation on CT was 10 mm (range, 2-22 mm), which decreased in 15 of 16 (94%) patients with available postoperative CT scans. Postoperative median thickness of perianeurysmal inflammation on CT was 6 mm (range, 0-13 mm). Hydroureteronephrosis persisted in two of nine (22.2%) patients at the end of follow-up. CONCLUSIONS Surgery in patients with inflammatory abdominal aortic aneurysms is associated with a substantial amount of perioperative complications. After surgery, the perianeurysmal inflammation decreases in most patients on follow-up CT. However, because the inflammatory process does not totally resolve, patients require lifelong surveillance for hydroureteronephrosis and development of aortoenteric fistulas.

Abstract
Objectives: The aim of this study was to evaluate short- and midterm outcomes of endovascular aneurysm repair in patients with inflammatory abdominal aortic aneurysm (IAAA) focusing on changes in perianeurysmal inflammation and hydronephrosis. Methods: A retrospective study was performed considering data prospectively gathered from 1998 to 2013 in 3 centers. Patient demographics, preoperative clinical characteristics, clinical presentation, preoperative imaging measurements, procedural, and postoperative data were collected. Main outcome was to define evolution of periaortic fibrosis and hydronephrosis at computed tomography angiography (CTA) during follow-up. Results: A total of 22 patients (male n = 20; mean age 70.9 years ± 9.3) were included (mean AAA diameter: 58 mm ± 11, symptomatic: 50%, ruptured: 9.1%). Hydroureteronephrosis was preoperatively diagnosed by CTA in 6 (27.3%) cases. Median clinical follow-up was 2.2 years (range 0.1-14.5). Nine patients died during follow-up. At 1, 2, 4, and 6 years, overall survival was 85.4%, 74.3%, 56.6%, and 49.5%, respectively. Among these 13 patients with CTA follow-up, the mean AAA diameter was 56.2 mm ± 15.5, and progression of sac diameter was detected in 1 (7.7%) patient. Median maximum thickness of perianeurysmal inflammation was 5 mm (range 2-11) and decreased/remained unchanged in 92.3% of patients. Regression of hydroureteronephrosis occurred in 3 of 5 patients available for follow-up. There were no cases of de novo hydroureteronephrosis. Conclusion: Endovascular treatment of IAAA has comparable short-term outcomes with non-IAAA. During midterm follow-up, aneurysm sac progression is rare, and perianeurysmal fibrosis decreases or remains unchanged in most cases. Hydronephrosis regression can occur in some but not all instances and thus warrants close surveillance.
