Treatment of secondary mitral regurgitation by transcatheter edge-to-edge repair using MitraClip
AbstractTranscatheter edge-to-edge repair (TEER) is becoming the standard invasive treatment for ventricular functional mitral regurgitation (MR). It is necessary to determine the severity of MR before treatment with MitraClip; however, the severity of secondary MR is usually underestimated compared with that of primary MR and varies temporally. Therefore, to accurately determine the severity of MR, it is important to correctly use the algorithm of the guidelines for valvular heart disease and aggressively perform stress echocardiography. Before performing TEER, the difficulty of the procedure should be evaluated. First, m...

Use of a Steerable Sheath for Completely Femoral Access in Branched Endovascular Aortic Repair Compared to Upper Extremity Access
ConclusionUsing a commercially available steerable sheath allowed successful cannulation of all branches in this cohort and was associated with significantly shorter branch cannulation times. Potentially, this technique can lower the stroke and brachial puncture site complication risk as well as reduce total intervention time and radiation dose.Level of Evidence2b, retrospective cohort study.

Endovascular Versus Open Surgical Repair for Ruptured Descending Aortic Pathologies: A Systematic Review and Meta-Analysis of Observational Studies
ConclusionsTEVAR seems to offer advantages in terms of early mortality and complications rate. Moreover, data on late mortality and re-intervention are encouraging to consider endovascular treatment comparable to open repair for acute thoracic aorta emergency on long-term follow-up.

Impairment of left atrial function in pediatric patients with repaired tetralogy of Fallot: a cardiovascular magnetic resonance imaging study
AbstractWe aimed to assess left atrial (LA) strain before LA dilatation in patients with repaired tetralogy of Fallot (rTOF) compared with healthy controls. We also determined the effects of right atrial (RA) dilatation on LA performance using cardiovascular magnetic resonance-feature tracking (CMR-FT). Forty-nine pediatric patients with rTOF and 36 age- and sex-matched healthy controls were prospectively recruited between June 2017 and August 2019. Balanced steady-state free precession (2D b-SSFP) cine, 2D late gadolinium enhancement (LGE) and phase-contrast (PC) sequences were acquired on 1.5 and 3.0 Tesla scanners. Both...

Association of carotid ultrasonography with perioperative stroke after thoracic aortic aneurysm treatment: a retrospective study
ConclusionsLower EDV and higher RI of bilateral CCAs were significantly associated with perioperative stroke after TAA treatment. Thus, CUS findings may help predict the occurrence of perioperative stroke.

Technique-Based Evaluation of Clinical Outcomes and Aortic Remodelling Following TEVAR in Acute and Subacute Type B Aortic Dissection
ConclusionEndovascular intervention for acute and subacute TBAD is safe with a high rate of technical success. STABILISE results in higher aortic remodelling at the infra-renal aorta (82%) compared to TEVAR alone (20%) but risks aortic rupture from balloon moulding.

Aortoesophageal fistula involving the central aortic arch salvaged with emergent percutaneous TEVAR, great vessel coverage and in vivo graft fenestration.
We describe an unusual and challenging case of TEVAR coverage of an AEF involving the central aortic arch immediately followed by in vivo endograft fenestration to regain arch vessel perfusion. In vivo fenestration, currently a procedure for emergency or investigational purposes only, was shown to be life saving in our case. The main complications associated with the procedure included stroke and infection, requiring esophagectomy and cervical diversion as well as ongoing antibiotic treatment.

Grade I traumatic aortic injury progression
This case highlights the importance of diagnosing Grade I aortic injuries after trauma. Although the prognosis for minimal aortic injury is typically quite good, the patient in this case suffered the unlikely complication of minimal intimal injury progression with resultant thromboembolism and massive stroke. Due to motion artifact and CT resolution limitations, the initial aortic injury was not detected. Thus, potentially life-saving measures such as serial CT monitoring of injury, blood pressure control, and endovascular repair were unable to be performed.

Preloaded Catheters and Guide-Wire Systems to Facilitate Catheterization During Fenestrated and Branched Endovascular Aortic Repair
ConclusionThis study shows high technical success and early lower limb reperfusion using PLS with trans-brachial access. The risk of stroke, especially in female patients, should be carefully assessed by review of preoperative arch imaging.

Inadvertent Arterial Placement of Central Venous Catheters: Systematic Review and Guidelines for Treatment
Publication date: Available online 14 September 2019Source: Journal of Vascular and Interventional RadiologyAuthor(s): David L. Dornbos, Shahid M. Nimjee, Tony P. SmithAbstractInadvertent arterial placement of central venous catheters carries serious sequelae, including pseudoaneurysm development and stroke. Although numerous strategies for therapeutic repair after arterial injury have been employed, no treatment provides a definitive standard of care. All articles published between January 2000 and July 2018 involving the placement of central venous catheters in the brachiocephalic or subclavian arteries, carotid artery, ...

Successful treatment of unexpected complication during aortic stent-grafting: retrieval of broken stent-graft tip by coaxial technique.
Abstract Thoracic aortic endovascular repair (TEVAR) is increasingly preferred as a treatment of choice in thoracic aortic diseases. Intravascular foreign body is one of the TEVAR-related complications similar to the other endovascular operations. Here, to the our best knowledge for the first time in the English literature, this report presents an extremely rare complication of a broken and stuck tip part of aortic stent-graft in the intravascular space and successful removal by using the coaxial technique. Thoracic aortic endovascular repair (TEVAR) has been increasingly preferred as the treatment of choice in th...

Can stress echocardiography identify patients who will benefit from percutaneous mitral valve repair?
AbstractThe aim of the current study was to investigate whether stress echocardiography improves selection of patients who might have clinical benefit from percutaneous mitral valve repair with the MitraClip. In total, 39 patients selected for MitraClip implantation underwent preprocedural low-dose stress (dobutamine or handgrip) echocardiography from which stroke volume, ejection fraction and MR grade were measured. Outcome after MitraClip implantation was determined by New York Heart Association classification and Quality of Life questionnaires. Clinical benefit from MitraClip treatment was defined as survival and NYHA c...

Endovascular repair of an acute symptomatic carotid artery dissection through the false dissecting carotid lumen.
Authors: Befera N, Griffin AS, Hauck EF Abstract A 48-year-old woman presented with an acute ischemic stroke (National Institutes of Health Stroke Scale (NIHSS) 21) six hours after symptom onset. Workup revealed a left cervical internal carotid artery (ICA) occlusive dissection, which was emergently reconstructed with a flow-diverting stent. A routine Duplex scan one hour later suggested reocclusion of the ICA, confirmed by angiography. The true lumen of the ICA could not be accessed and therefore the "false lumen" of the ICA dissection was entered proximally. The true lumen and ultimately the flow-diverting stent ...
