Abstract
The background of this paper is to report the mortality at 30 and 90 days and at mean follow-up after open abdominal aortic aneurysms (AAA) emergent repair and to identify predictive risk factors for 30- and 90-day mortality. Between 1997 and 2002, 104 patients underwent emergent AAA open surgery. Symptomatic and ruptured AAAs were observed, respectively, in 21 and 79% of cases. Mean patient age was 70 (SD 9.2) years. Mean aneurysm maximal diameter was 7.4 (SD 1.6) cm. Primary endpoints were 30- and 90-day mortality. Significant mortality-related risk factor identification was the secondary endpoint. Open repair trend and its related perioperative mortality with a per-year analysis and a correlation subanalysis to identify predictive mortality factor were performed. Mean follow-up time was 23 (SD 23) months. Overall, 30-day mortality was 30%. Significant mortality-related risk factors were the use of computed tomography (CT) as a preoperative diagnostic tool, AAA rupture, preoperative shock, intraoperative cardiopulmonary resuscitation (CPR), use of aortic balloon occlusion, intraoperative massive blood transfusion (MBT), and development of abdominal compartment syndrome (ACS). Previous abdominal surgery was identified as a protective risk factor. The mortality rate at 90 days was 44%. Significant mortality-related risk factors were AAA rupture, aortocaval fistula, peripheral artery disease (PAD), preoperative shock, CPR, MBT, and ACS. The mortality rate at follow-up was 45%. Correlation analysis showed that MBT, shock, and ACS are the most relevant predictive mortality factor at 30 and 90 days. During the transition period from open to endovascular repair, open repair mortality outcomes remained comparable with other contemporary data despite a selection bias for higher risk patients. MBT, shock, and ACS are the most pronounced predictive mortality risk factors.

Abstract
History of major gastrointestinal (GI) bleeding may represent a frequent clinical indication for left atrial appendage occlusion (LAAO) in patients with non-valvular atrial fibrillation (AF). This study aims to investigate the procedural safety and long-term outcome of patients with previous major GI bleeding (MGIB) who underwent LAAO. Data from the Amplatzer Cardiac Plug multicenter registry on 1,047 patients were analyzed. Patients with previous MGIB as indication for LAAO were compared with patients without previous MGIB. A total of 151 patients (14.4%) with previous MGIB were identified. Periprocedural major bleeding events were more frequent in patients with previous MGIB (4.0% vs 0.8%, p = 0.001). With an average follow-up of 1.3 years, the observed annual rate of stroke/transient ischemic attack and major bleeding for patients with previous MGIB were 2.1% (61.4% relative reduction according to the Congestive Heart failure, Hypertension, Age ≥75 (doubled), Diabetes, Stroke (doubled), Vascular disease, Age 65-74, and Sex (female) [CHA2DS2-VASc] score) and 4.6% (20.1% relative reduction according to the expected rate based on the Hypertension, Abnormal renal/liver function (1 point each), Stroke, Bleeding history or predisposition, Labile INR, Elderly (>65 years), Drugs/alcohol concomitantly (1 point each) [HAS-BLED] score), respectively. In conclusion, in patients with non-valvular atrial fibrillation and previous MGIB, LAAO was associated with a low annual rate of stroke/transient ischemic attack. Periprocedural major bleeding events were more frequent in this specific population although the annual major bleeding rate showed a 20.1% relative risk reduction according to the HAS-BLED score.

Abstract
AIMS We aimed to demonstrate the feasibility and investigate the safety of a novel, self-expanding trans-catheter heart valve in a selected patient population with severe aortic stenosis. METHODS AND RESULTS Between January and September 2013, a total of 21 patients with symptomatic severe aortic stenosis were eligible for transcatheter aortic valve implantation (TAVI) with the self-expanding NVT Allegra bioprosthesis (New Valve Technology, Hechingen, Germany) at two cardiovascular centres. Patients were elderly (age 83.8±4 years), predominantly female (95.2%), and all were considered to be at prohibitive risk for surgical aortic valve replacement (logistic EuroSCORE 30.4±11%). Procedural and device success was achieved in 95.2% and 85.7%, respectively. Echocardiographic assessment at discharge showed favourable haemodynamic results with a reduction of the mean transvalvular aortic gradient from 48.0±21 mmHg to 8.9±3 mmHg. In the majority of patients (90.5%), none or trace aortic regurgitation was recorded. Permanent pacemaker implantation was required in 23.8% of patients within the first 30 days of follow-up. Apart from one procedural death, no other serious adverse events were observed during the periprocedural period. TAVI with the NVT Allegra system was highly effective in alleviating symptoms and reducing NYHA functional class at 30-day follow-up. CONCLUSIONS The first-in-human experience with the NVT Allegra transcatheter heart valve prosthesis was associated with a high rate of procedural success. Furthermore, the NVT Allegra bioprosthesis was able to achieve favourable haemodynamic results and effectively alleviate symptoms at 30-day follow-up. The larger, multicentre NAUTILUS study will provide further information on the safety and efficacy of this novel, second-generation transcatheter aortic bioprosthesis.

Abstract
OBJECTIVES Routine device surveillance after successful left atrial appendage closure is recommended to evaluate for intermediate to late complications. The aim of this study was to assess the incidence and clinical impact of these complications on cardiovascular events. METHODS Centers participating in the Amplatzer Cardiac Plug multicenter study were requested to submit their post-procedural transesophageal echocardiograms for independent adjudication. Thirteen of 22 centers contributed all their post-procedural echocardiograms, which included 344 from 605 consecutive patients. These images were submitted to a core laboratory and reviewed by 2 independent experts for peri-device leak, device-associated thrombus, device embolization, device migration, left atrial appendage thrombus, and left atrial thrombus. Clinical events were prospectively collected by each center. RESULTS Of the 344 transesophageal echocardiograms, 339 were deemed analyzable. Patients' mean age was 74.4 ± 7.5 years, and 67.3% were men. The mean CHADS2 score was 2.7 ± 1.3, the mean CHA2DS2-VASc score was 4.3 ± 1.5, and the mean HAS-BLED score was 3.0 ± 1.2. Amplatzer Cardiac Plug implantation was successful in all patients. Periprocedural major adverse events occurred in 2.4%. Median clinical follow-up duration was 355 days (range 179 to 622 days). Follow-up transesophageal echocardiography was performed after a median of 134 days (range 88 to 227 days). Device-associated thrombus was observed in 3.2% and peri-device leak in 12.5% (5.5% minimal, 5.8% mild, 0.6% moderate, 0.6% severe). Neither device-associated thrombus nor peri-device leak was associated with an increased risk for cardiovascular events. Independent predictors of device-associated thrombus were smoking (odds ratio: 5.79; p = 0.017) and female sex (odds ratio: 4.22; p = 0.027). CONCLUSIONS Following successful left atrial appendage closure with the Amplatzer Cardiac Plug, the presence of peri-device leak was relatively low, and device-associated thrombus was infrequent. Neither was associated with increased risk for thromboembolism.

Abstract
Cardioembolic strokes are generally more lethal and disabling than other source of strokes. Data from PROTECT AF (Watchman Left Atrial Appendage Closure Technology for Embolic Protection in Patients With Atrial Fibrillation) suggest that strokes after left atrial appendage occlusion (LAAO) with the Watchman device are less disabling than those in the warfarin group. No data assessing the severity of strokes after LAAO with the AMPLATZER Cardiac Plug (ACP) are available. The objective of the study was to evaluate the severity of cerebrovascular events after LAAO with the ACP in a population mostly characterized by an absolute or relative contraindication to oral anticoagulation. Data from the ACP multicenter registry were analyzed. Disabling strokes were defined as those with a modified Rankin score of 3 to 6 at 90 days after the event. A total of 1,047 subjects were included. The mean age and CHADS2 score were 75 ± 8 years and 2.8 ± 1.3, respectively. Procedural success was achieved in 97.3% and 4.9% of the patients presented procedural major adverse events. Clinical follow-up was complete in 98.2% of patients with a median of 13 months. There were 9 strokes (0.9%), 9 transient ischemic attacks (0.9%), and no intracranial hemorrhages (0%) at follow-up. After excluding 2 patients with pre-LAAO disability, functional assessment showed disabling events in 3 (19%) of the remaining 16 patients. The median time of presentation was 420 days (interquartile range 234 to 671) after LAAO, and 17 patients (94%) were on single-antiplatelet therapy when the event occurred. According to our results, cerebrovascular events after LAAO with the ACP system were infrequent and mostly nondisabling.

Abstract
Abstract—
Heart rate (HR) lowering by β-blockade was shown to be beneficial after myocardial infarction. In contrast, HR lowering with ivabradine was found to confer no benefits in 2 prospective randomized trials in patients with coronary artery disease. We hypothesized that this inefficacy could be in part related to ivabradine’s effect on central (aortic) pressure. Our study included 46 patients with chronic stable coronary artery disease who were randomly allocated to placebo (n=23) or ivabradine (n=23) in a single-blinded fashion for 6 months. Concomitant baseline medication was continued unchanged throughout the study except for β-blockers, which were stopped during the study period. Central blood pressure and stroke volume were measured directly by left heart catheterization at baseline and after 6 months. For the determination of resting HR at baseline and at follow-up, 24-hour ECG monitoring was performed. Patients on ivabradine showed an increase of 11 mm Hg in central systolic pressure from 129±22 mm Hg to 140±26 mm Hg (
P
=0.02) and in stroke volume by 86±21.8 to 107.2±30.0 mL (
P
=0.002). In the placebo group, central systolic pressure and stroke volume remained unchanged. Estimates of myocardial oxygen consumption (HR×systolic pressure and time-tension index) remained unchanged with ivabradine.The decrease in HR from baseline to follow-up correlated with the concomitant increase in central systolic pressure (
r
=−0.41,
P
=0.009) and in stroke volume (
r
=−0.61,
P
<0.001). In conclusion, the decrease in HR with ivabradine was associated with an increase in central systolic pressure, which may have antagonized possible benefits of HR lowering in coronary artery disease patients.

Abstract
Atrial fibrillation (AF) is the most common atrial arrhythmia, with a prevalence of 1-2% in the general population. It increases with age, affecting approximately 7% of individuals age >65 years and 15-20% of octogenarians. The human left atrium has a blind sac-like remnant, called left atrial appendage (LAA). It originates from a primordial pulmonary vein. Due to its complicated structure, blind end and inner surface trabeculated by pectinate muscles, thrombi in nonvalvular AF form almost exclusively in the LAA and not in the smooth-walled left atrium. For the last 50 years, oral anticoagulation (OAC) with vitamin K antagonists (VKAs) has been the only treatment option to prevent stroke and systemic embolism from thrombi in AF. More recently, non-vitamin K-dependant oral anticoagulants (NOACs) have been shown to be noninferior or even superior to VKA with respect to efficacy and safety. In light of the limitations of indefinite OAC, particularly among patients at increased risk for bleeding and because thrombi arise predominantly from the LAA among AF patients, exclusion of the LAA with closure devices (LAAC) provides a novel treatment strategy for prevention of stroke and bleeding. Recently, LAAC has been compared with VKA therapy in prospective randomised trials with promising results. Today, the decision to provide the most appropriate treatment for a patient with AF (OAC, NOAC or LAAC) is complex and needs to be individualised. This review provides an update on the current state of LAAC in the field of stroke prevention in patients suffering from nonvalvular AF. We describe the pathophysiology of the LAA with regard to stroke. Aside from the evidence and limitations of anticoagulation as the classical treatment paradigm for stroke prevention, devices and techniques for LAAC are outlined and the current clinical evidence with regard to efficacy and safety is reviewed. Finally, contemporary recommendations for patient selection are provided.

Abstract
OBJECTIVES This study compared clinical outcomes and revascularization strategies among patients presenting with low ejection fraction, low-gradient (LEF-LG) severe aortic stenosis (AS) according to the assigned treatment modality. BACKGROUND The optimal treatment modality for patients with LEF-LG severe AS and concomitant coronary artery disease (CAD) requiring revascularization is unknown. METHODS Of 1,551 patients, 204 with LEF-LG severe AS (aortic valve area <1.0 cm(2), ejection fraction <50%, and mean gradient <40 mm Hg) were allocated to medical therapy (MT) (n = 44), surgical aortic valve replacement (SAVR) (n = 52), or transcatheter aortic valve replacement (TAVR) (n = 108). CAD complexity was assessed using the SYNTAX score (SS) in 187 of 204 patients (92%). The primary endpoint was mortality at 1 year. RESULTS LEF-LG severe AS patients undergoing SAVR were more likely to undergo complete revascularization (17 of 52, 35%) compared with TAVR (8 of 108, 8%) and MT (0 of 44, 0%) patients (p < 0.001). Compared with MT, both SAVR (adjusted hazard ratio [adj HR]: 0.16; 95% confidence interval [CI]: 0.07 to 0.38; p < 0.001) and TAVR (adj HR: 0.30; 95% CI: 0.18 to 0.52; p < 0.001) improved survival at 1 year. In TAVR and SAVR patients, CAD severity was associated with higher rates of cardiovascular death (no CAD: 12.2% vs. low SS [0 to 22], 15.3% vs. high SS [>22], 31.5%; p = 0.037) at 1 year. Compared with no CAD/complete revascularization, TAVR and SAVR patients undergoing incomplete revascularization had significantly higher 1-year cardiovascular death rates (adj HR: 2.80; 95% CI: 1.07 to 7.36; p = 0.037). CONCLUSIONS Among LEF-LG severe AS patients, SAVR and TAVR improved survival compared with MT. CAD severity was associated with worse outcomes and incomplete revascularization predicted 1-year cardiovascular mortality among TAVR and SAVR patients.

Abstract
Left atrial appendage occlusion (LAAO) is emerging as a promising alternative to oral anticoagulation. Because aged patients present a greater risk of not only cardioembolic events but also major bleeding, LAAO might represent a valid alternative as this would allow oral anticoagulation cessation while keeping cardioembolic protection. The objective of the study was to explore the safety and efficacy of LAAO in elderly patients. Data from the AMPLATZER Cardiac Plug multicenter registry were analyzed. The cohort was categorized in 2 groups (<75 vs ≥ 75 years). A total of 1,053 subjects were included in the registry. Of them, 219 were excluded because of combined procedures. As a result, 828 subjects were included (54.6% ≥ 75 years). Procedural success was high and similar in both groups (97.3%). Acute procedural major adverse events were not statistically different among groups (3.2% in <75 years vs 5.1%; p = 0.17) although stratified analysis showed a higher incidence of cardiac tamponade in elderly patients (0.5% vs 2.2%; p = 0.04). With a median follow-up of 16.8 months, no significant differences in stroke/TIA (1.9% vs 2.3%; p = 0.89) and major bleeding (1.7% vs 2.6%; p = 0.54) were observed. In conclusion, LAAO was associated with similar procedural success in patients aged <75 and ≥ 75 years although older patients had a higher incidence of cardiac tamponade. At follow-up, stroke and major bleeding rates were similar among groups.

Abstract
AIMS To evaluate the accuracy and reproducibility of aortic annulus sizing using a multislice computed tomography (MSCT) based aortic root reconstruction tool compared with conventional imaging among patients evaluated for transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS Patients referred for TAVR underwent standard preprocedural assessment of aortic annulus parameters using MSCT, angiography and transoesophageal echocardiography (TEE). Three-dimensional (3D) reconstruction of MSCT images of the aortic root was performed using 3mensio (3mensio Medical Imaging BV, Bilthoven, The Netherlands), allowing for semi-automated delineation of the annular plane and assessment of annulus perimeter, area, maximum, minimum and virtual diameters derived from area and perimeter (aVD and pVD). A total of 177 patients were enrolled. We observed a good inter-observer variability of 3D reconstruction assessments with concordance coefficients for agreement of 0.91 (95% CI: 0.87-0.93) and 0.91 (0.88-0.94) for annulus perimeter and area assessments, respectively. 3D derived pVD and aVD correlated very closely with a concordance coefficient of 0.97 (0.96-0.98) with a mean difference of 0.5±0.3 mm (pVD-aVD). 3D derived pVD showed the best, but moderate concordance with diameters obtained from coronal MSCT (0.67, 0.56-0.75; 0.3±1.8 mm), and the lowest concordance with diameters obtained from TEE (0.42, 0.31-0.52; 1.9±1.9 mm). CONCLUSIONS MSCT-based 3D reconstruction of the aortic annulus using the 3mensio software enables accurate and reproducible assessment of aortic annulus dimensions.

Abstract
BACKGROUND Transcatheter left atrial appendage (LAA) occlusion has been proven to be an effective treatment for stroke prophylaxis in patients with atrial fibrillation. For this purpose, the Amplatzer cardiac plug (ACP) was introduced. Its second generation, the Amulet, was developed for easier delivery, better coverage, and reduction of complications. AIM To investigate the safety and efficacy of first generation versus second generation Amplatzer occluders for LAA occlusion. METHODS Retrospective analysis of prospectively collected data from the LAA occlusion registries of the Bern and Zurich university hospitals. Comparison of the last consecutive 50 ACP cases versus the first consecutive 50 Amulet cases in patients with non-valvular atrial fibrillation. For safety, a periprocedural combined endpoint, which is composed of death, stroke, cardiac tamponade, and bailout by surgery was predefined. For efficacy, the endpoint was procedural success. RESULTS There were no differences between the two groups in baseline characteristics. The percentage of associated interventions during LAA occlusion was high in (78% with ACP vs. 70% with Amulet p = ns). Procedural success was similar in both groups (98 vs. 94%, p = 0.61). The combined safety endpoint for severe adverse events was reached by a similar rate of patients in both groups (6 vs. 8%, p = 0.7). Overall complication rate was insignificantly higher in the ACP group, which was mainly driven by clinically irrelevant pericardial effusions (24 vs. 14%, p = 0.31). Death, stroke, or tamponade were similar between the groups (0 vs. 2%, 0 vs. 0%, or 6 vs. 6%, p = ns). CONCLUSION Transcatheter LAA occlusion for stroke prophylaxis in patients with atrial fibrillation can be performed with similarly high success rates with first and second generations of Amplatzer occluders. According to this early experience, the Amulet has failed to improve results of LAA occlusion. The risk for major procedural adverse events is acceptable but has to be taken into account when selecting patients for LAA occlusion, a preventive procedure.

Abstract
Background Concurrent cardiac diseases are frequent among elderly patients and invite simultaneous treatment to ensure an overall favourable patient outcome. Aim To investigate the feasibility of combined single-session percutaneous cardiac interventions in the era of transcatheter aortic valve implantation (TAVI). Methods This prospective, case–control study included 10 consecutive patients treated with TAVI, left atrial appendage occlusion and percutaneous coronary interventions. Some in addition had patent foramen ovale or atrial septal defect closure in the same session. The patients were matched in a 1:10 manner with TAVI-only cases treated within the same time period at the same institution regarding their baseline factors. The outcome was validated according to the Valve Academic Research Consortium (VARC) criteria. Results Procedural time (126±42 vs 83±40 min, p=0.0016), radiation time (34±8 vs 22±12 min, p=0.0001) and contrast dye (397±89 vs 250±105 mL, p<0.0001) were higher in the combined intervention group than in the TAVI-only group. Despite these drawbacks, no difference in the VARC endpoints was evident during the in-hospital period and after 30 days (VARC combined safety endpoint 32% for TAVI only and 20% for combined intervention, p=1.0). Conclusions Transcatheter treatment of combined cardiac diseases is feasible even in a single session in a high-volume centre with experienced operators.

Abstract
Transcatheter aortic valve implantation is a feasible therapeutic option for selected patients with severe aortic stenosis and high or prohibitive risk for standard surgery. Lung transplant recipients are often considered high-risk patients for heart surgery because of their specific transplant-associated characteristics and comorbidities. We report a case of successful transfemoral transcatheter aortic valve replacement in a lung transplant recipient with a symptomatic severe aortic stenosis, severe left ventricular dysfunction, and end-stage renal failure 9 years after bilateral lung transplantation.
