Abstract
Coronary atherectomy has been around for many years, and the body of evidence for its use in complex calcified lesions has grown. Calcific coronary disease presents a particularly challenging clinical scenario in PCI, having poorer outcomes than noncalcified lesions. This study is the first to identify calcified nodules as an independent predictor of worse outcomes after atherectomy and PCI. Continued study of lesion characteristics will improve our understanding of PCI outcomes and help manage patients in the long-term after PCI and stenting.

Abstract
Identification of hypoattenuated leaflet thickening (HALT) and subacute leaflet thrombosis has become widely recognized. Patients with anatomical changes associated with moderate or greater aortic regurgitation (larger sinus of Valsalva and eccentric left ventricular remodeling) appear to have less HALT early postprocedure compared with those without. Further research on the risk factors including anatomical and hemodynamic variables should further our knowledge of these entities so we can better manage patient both pre and post TAVR.

Abstract
BACKGROUND Chest radiation therapy (CRT) for malignant thoracic neoplasms is associated with development of valvular heart disease years later. As previous radiation exposure can complicate surgical treatment, transcatheter aortic valve replacement (TAVR) has emerged as an alternative. However, outcomes data are lacking for TAVR patients with a history of CRT. METHODS We conducted a retrospective study of all patients who underwent a TAVR procedure at a single institution between September 2012 and November 2018. Among 1341 total patients, 50 had previous CRT. These were propensity-matched in a 1:2 ratio to 100 patients without history of CRT. Thirty-day adverse events were analyzed with generalized estimating equation models. Overall mortality was analyzed with stratified Cox regression modelling. RESULTS Median clinical follow-up was 24 months (interquartile range [IQR], 12-44 months). There was no difference between CRT and non-CRT patients in overall mortality (hazard ratio [HR] 0.84 [0.37-1.90], P = 0.67), 30-day mortality (HR 3.1 [0.49-20.03], P = 0.23), or 30-day readmission rate (HR 1.0 [0.43-2.31], P = 1). There were no differences in the rates of most adverse events, but patients with CRT history had higher rates of postprocedural respiratory failure (HR 3.63 [1.32-10.02], P = 0.01) and permanent pacemaker implantation (HR 2.84 [1.15-7.01], P = 0.02). CONCLUSIONS For patients with aortic valve stenosis and previous CRT, TAVR is safe and effective, with outcomes similar to those in the general aortic stenosis population. Patients with history of CRT are more likely to have postprocedural respiratory failure and to require permanent pacemaker implantation.

Abstract
Thoracic aortic disease has usually been treated with surgery. Thoracic endovascular aortic repair is challenging if supra-aortic vessels are involved. In situ fenestration of the main graft from a retrograde approach while using bare-metal stents as bridge stents appears to be a safe and practical technique.

Abstract
The transcatheter pulmonary valve replacement technique has evolved over the past decade. There is risk of injuring the tricuspid valve if the transcatheter device is advanced uncovered across the right heart. Advancing a long sheath past the landing zone and uncovering the device can help mitigate this risk, at the expense of requiring larger-caliber sheaths. Additional refinements of the technique such as the one reported here, along with improvements in device design, are likely to further reduce complications.

Abstract
Atherothrombotic burden (ATB) correlates with myocardial blush grade (MBG), a known predictor of mortality and outcome after ST-elevation myocardial infarction. Quantitative or semiquantitative analysis of ATB with optical coherence tomography may assist interventional cardiologists in post-PCI prognostication and, perhaps, in rendering more aggressive antiplatelet therapy. Future studies comparing treatment strategies for post-PCI patients with elevated ATB or depressed MBG may identify best practices after acute coronary syndromes.

Abstract
Patients with PAD have worse outcomes after TAVR. The extent and distribution of PAD are important considerations in determining TAVR feasibility and choosing an access site. Further research is needed to establish the best approaches to treating patients with aortic and iliofemoral disease severe enough to limit device delivery.

Abstract
Multimodality interventions, including both percutaneous and surgical approaches, are paramount in maintaining vascular fistula and graft patency in hemodialysis patients. Mechanical thrombectomy with Angiojet AVX or Solent Proxi of AVFs and AVGs achieved acceptable technical and clinical success rates (>90%) in combination with adjuvant percutaneous transluminal angioplasty and stenting. Future prospective studies using intravascular imaging before therapy may be useful when deciding which treatment modalities to use for AVFs and AVGs.

Abstract
Aim: This study compared real-world complication rates, hospitalization duration and costs, among patients undergoing arterial repair using the Perclose ProGlide (ProGlide) versus surgical cutdown (Cutdown). Materials & methods: Retrospective study of matched patients who underwent transcatheter aortic valve replacement/repair, endovascular abdominal aortic aneurysm repair, thoracic endovascular aortic repair or balloon aortic valvuloplasty with arterial repair by either ProGlide or Cutdown between 1 January 2013 and 24 April 2017. Results: Infections and blood transfusions were lower in the ProGlide cohort. Patients in the ProGlide cohort had a 42.5% shorter index hospitalization, which corresponded to US$14,687 lower costs. Conclusion: The use of ProGlide for arterial repair was associated with significantly lower transfusion rates, shorter index hospitalization and lower hospitalization costs compared with surgical cutdown.

Abstract
Background Perioperative health care utilization and costs in patients undergoing elective fast-track vs standard endovascular aneurysm repair (EVAR) remain unclear. Methods The fast-track EVAR group included patients treated with a 14 Fr stent graft, bilateral percutaneous access, no general anesthesia or intensive care monitoring, and next-day hospital discharge. The standard EVAR group was identified from Medicare administrative claims using a matching algorithm to adjust for imbalances in patient characteristics. Hospital outcomes included operating room time, intensive care monitoring, hospital stay, secondary interventions, and major adverse events (MAEs). Perioperative outcomes occurring from hospital discharge to 30 days postdischarge included MAE, secondary interventions, and unrelated readmissions. Results Among 1000 matched patients (250 fast-track; 750 standard), hospital outcomes favored the fast-track EVAR group, including shorter operating room time (2.30 vs 2.83 hrs, P<0.001), shorter hospital stay (1.16 vs 1.69 d, P<0.001), less need for intensive care monitoring (4.4% vs 48.0%, P<0.001), and lower secondary intervention rate (0% vs 2.4%, P=0.01). Postdischarge outcomes also favored fast-track EVAR with a lower rate of MAE (0% vs 7.2%, P<0.001) and all-cause readmission (1.6% vs 6.8%, P=0.001). The total cost to the health care system during the perioperative period was $26,730 with fast-track EVAR vs $30,730 with standard EVAR. Total perioperative health care costs were $4000 (95% CI: $3130–$4830) lower with fast-track EVAR vs standard EVAR, with $2980 in savings to hospitals and $1030 savings to health care payers. Conclusion A fast-track EVAR protocol using a 14 Fr stent graft resulted in shorter procedure time, lower intensive care utilization, faster discharge, lower incidence of MAE, lower readmission rates, and lower perioperative costs compared to standard EVAR.

Abstract
Background:
Open surgical closure and small-bore suture-based preclosure devices have limitations when used for transcatheter aortic valve replacement, percutaneous endovascular abdominal aortic aneurysm repair, or percutaneous thoracic endovascular aortic aneurysm repair. The MANTA vascular closure device is a novel collagen-based technology designed to close large bore arteriotomies created by devices with an outer diameter ranging from 12F to 25F. In this study, we determined the safety and effectiveness of the MANTA vascular closure device.
Methods and Results:
A prospective, single arm, multicenter investigation in patients undergoing transcatheter aortic valve replacement, percutaneous endovascular abdominal aortic aneurysm repair, or thoracic endovascular aortic aneurysm repair at 20 sites in North America. The primary outcome was time to hemostasis. The primary safety outcomes were accessed site-related vascular injury or bleeding complications. A total of 341 patients, 78 roll-in, and 263 in the primary analysis cohort, were entered in the study between November 2016 and September 2017. For the primary analysis cohort, transcatheter aortic valve replacement was performed in 210 (79.8%), and percutaneous endovascular abdominal aortic aneurysm repair or thoracic endovascular aortic aneurysm repair was performed in 53 (20.2%). The 14F MANTA was used in 42 cases (16%), and the 18F was used in 221 cases(84%). The mean effective sheath outer diameter was 22F (7.3 mm). The mean time to hemostasis was 65±157 seconds with a median time to hemostasis of 24 seconds. Technical success was achieved in 257 (97.7%) patients, and a single device was deployed in 262 (99.6%) of cases. Valve Academic Research Consortium-2 major vascular complications occurred in 11 (4.2%) cases: 4 received a covered stent (1.5%), 3 had access site bleeding (1.1%), 2 underwent surgical repair (0.8%), and 2 underwent balloon inflation (0.8%).
Conclusions:
In a selected population, this study demonstrated that the MANTA percutaneous vascular closure device can safely and effectively close large bore arteriotomies created by current generation transcatheter aortic valve replacement, percutaneous endovascular abdominal aortic aneurysm repair, and thoracic endovascular aortic aneurysm repair devices.

Abstract
Juxtarenal abdominal aortic aneurysms (AAAs) are difficult to treat because they often have little or no proximal aortic neck. Patients with this complex anatomy are not usually candidates for an endovascular aneurysm repair (EVAR). Chimney-graft EVAR has been introduced, but type Ia endoleak is a typical risk. We have begun using EndoAnchors to determine whether this risk can be reduced. From July 2013 through July 2014, we used the chimney-graft EVAR technique in 5 patients whose juxtarenal AAAs had a short or no proximal aortic neck. During the procedure, we implanted EndoAnchors as needed. Postprocedurally, at 30 days, and through end of follow-up (duration, 11-18 mo), all patients had patent endografts without type Ia endoleak (our primary endpoint), visceral stent-graft thrombosis, or renal complications. One patient who received 4 chimney grafts had a postprocedural type II endoleak, which was treated with embolization. We found it feasible to use EndoAnchors with the chimney-graft technique to prevent type Ia endoleaks in the treatment of juxtarenal AAAs. Further studies are needed to validate this adjunctive technique and to determine its durability.
