Stent “Hygiene”
Key Points Studies demonstrate ideal Stent expansion with prolonged inflations. Longer inflations, a mediator of greater stent expansion, lower immediate, subacute, and late stent failure. Research should focus on components of stent deployment that optimize early and late stent outcomes. (Source: Catheterization and Cardiovascular Interventions)

A novel user ‐friendly transcatheter edge‐to‐edge mitral valve repair device in a porcine model
ConclusionsIt was feasible and safe to use ValveClamp to perform a catheter ‐mediated edge‐to‐edge mitral valve repair in a porcine model. This system is potentially applicable as a novel user‐friendly system for the treatment of MR. (Source: Catheterization and Cardiovascular Interventions)

Toward predictive modeling of catheter ‐based pulmonary valve replacement into native right ventricular outflow tracts
ConclusionsThis study demonstrates that pre ‐implant modeling which assumes a rigid vessel wall may not accurately predict the degree of distal RVOT expansion following actual device placement. We suggest the potential for virtual modeling of TPVR to be a useful adjunct to procedural planning, but further development is needed. (Source: Catheterization and Cardiovascular Interventions)

Feasibility study of a synchronized diastolic injection with low contrast volume for proper quantitative assessment of aortic regurgitation in porcine models
ConclusionSynchronized diastolic injection with low contrast volume produced denser images in the aortic root and more accurate than the conventional injection; thus, may be an appealing alternative for assessment of AR post TAVR. (Source: Catheterization and Cardiovascular Interventions)

Recovery of myocardial perfusion after percutaneous coronary intervention of chronic total occlusions is comparable to hemodynamically significant non ‐occlusive lesions
ConclusionsMyocardial perfusion findings are slightly more hampered in patients with a CTO before and after PCI. Percutaneous revascularization of CTOs, however, improves absolute myocardial perfusion similarly to PCI of hemodynamically significant non ‐CTO lesions, leading to satisfying results.

Cleft mitral leaflets and severe mitral regurgitation: Testing the limits of percutaneous mitral valve repair
We present two cases of successful repair of severe MR and cleft mitral leaflets. In the first case, a 52‐year‐old male with a dilated cardiomyopathy and an ejection fraction (EF) of 15% presented in decompensated heart failure. Workup revealed a pseudo‐cleft anterior mitral leaflet and a cleft posterior leaflet. A strategy to treat the restricted po sterior leaflet lateral of the posterior cleft with a provisional second clip resulted in trace residual MR with only one clip, and an EF improvement to 50% at 2‐month follow‐up. In the second case, an 80‐year‐old male with a history of obstructive CAD with a nor...

Effect of prior stroke on long ‐term outcomes of percutaneous coronary interventions in Chinese patients: A large single‐center study
ConclusionsPrior stroke history was the only predictor of risk of post ‐PCI stroke. The noncerebrovascular adverse events were not increased after adjusted analyses of baseline characteristics and propensity analyses. (Source: Catheterization and Cardiovascular Interventions)

Hybrid transcatheter tricuspid valve ‐in‐valve placement of an Edwards Sapien XT valve in palliated hypoplastic left heart syndrome
We report successful hybrid trans ‐atrial implantation of an Edwards Sapien XT valve into a dysfunctional bioprosthetic valve in the tricuspid position of a 9‐year‐old patient with HLHS. There was an immediate fall in the Fontan pressures combined with significant clinical improvement and the valve continues to function well n early 3 years post implant. To the best of our knowledge, this is the first described implantation of a transcatheter valve in this specific position and anatomy. (Source: Catheterization and Cardiovascular Interventions)

Feasibility, safety and midterm follow ‐up of patients after nonsurgical closure of atrial septal defects using very large 40–46 mm nitinol septal occluders
ConclusionsOccluders larger than 38 mm in appropriately selected patients are feasible, successful and safe in majority and often require special deployment techniques. Complications during and after the procedure were infrequent. Very large defects with any deficient margin except retroaortic rim should be excluded from device closure.

Long ‐term results of carotid stenting and risk factors in patients with severe carotid artery stenosis undergoing subsequent cardiac surgery
ConclusionsIn this study with staged CAS followed by cardiac surgery, we confirm previously reported event ‐free survival rates and identify several risk factors for the composite outcome. Future studies are needed to confirm the importance of the identified risk factors and to assess their predictive ability. (Source: Catheterization and Cardiovascular Interventions)

Furthermore, the integrated 3D fusion image might have a potential as an intraprocedural imaging modality to contribute to the development of a safer TAVI procedure.
