Prespecified Risk Criteria Facilitate Adequate Discharge and Long‐Term Outcomes After Transfemoral Transcatheter Aortic Valve Implantation

Background Despite the availability of guidelines for the performance of transcatheter aortic valve implantation (TAVI), current treatment pathways vary between countries and institutions, which impact on the mean duration of postprocedure hospitalization. Methods and Results This was a prospective, multicenter registry of 502 patients to validate the appropriateness of discharge timing after transfemoral TAVI, using prespecified risk criteria from FAST‐TAVI (Feasibility and Safety of Early Discharge After Transfemoral [TF] Transcatheter Aortic Valve Implantation), based on hospital events within 1‐year after discharge. The end point—a composite of all‐cause mortality, vascular access–related complications, permanent pacemaker implantation, stroke, cardiac rehospitalization, kidney failure, and major bleeding—was reached in 27.0% of patients (95% CI, 23.3–31.2) within 1 year after intervention; 7.5% (95% CI, 5.5–10.2) had in‐hospital complications before discharge and 19.6% (95% CI, 16.3–23.4) within 1 year after discharge. Overall mortality within 1 year after discharge was 7.3% and rates of cardiac rehospitalization 13.5%, permanent pacemaker implantation 4.2%, any stroke 1.8%, vascular‐access–related complications 0.7%, life‐threatening bleeding 0.7%, and kidney failure 0.4%. Composite events within 1 year after discharge were observed in 18.8% and 24.3% of patients with low risk of complications/early (≤3 days) discharge and high risk and discharged late (>3 days) (concordant discharge), respectively. Event rate in patients with discordant discharge was 14.3% with low risk but discharged late and increased to 50.0% in patients with high risk but discharged in ≤3 days. Conclusions The FAST‐TAVI risk assessment provides a tool for appropriate, risk‐based discharge that was validated with the 1‐year event rate after transfemoral TAVI.

Immediate Versus Delayed Endovascular Treatment of Post-Traumatic Aortic Pseudoaneurysms and Type B Dissections: Retrospective Analysis and Premises to the Upcoming European Trial

Background Stent grafting has been reported as a viable therapeutic option for the delayed treatment of traumatic rupture of the aortic isthmus as well as reconstruction of thoracic aortic dissections. We tested the hypothesis of whether immediate endovascular management offers clinical and pathological advantages over a delayed approach in patients with post-traumatic aortic pseudoaneurysms (PAPs) and Stanford type-B dissections (TBDs). Methods Thirty-one consecutive patients who were admitted with diagnosis of either PAP (n=10; 33.4±8.7 years) or TBD (n=21; 58.2±8.4 years) were respectively divided into 2 groups according to the timing of diagnosis and endovascular treatment after the traumatic or pathologic event: immediate ([lteq]2 weeks; PAP=6 and TBD=7) and delayed (>2 weeks; PAP=4 and TBD=14). Excluder®-Gore (11 in PAP and 8 in TBD) and Talent™-Medtronic (1 in PAP and 7 in TBD) endovascular stent grafts were deployed. Follow-up was performed at 3 months, 6 months, and 1 year and based on laboratory tests; chest angio-computed tomography scans of chest, abdomen, and pelvis; and transesophageal echocardiography. Results The endovascular procedure proved uneventful in all PAP patients who underwent either immediate or delayed treatment. In 1 PAP patient with delayed treatment, surgical removal of the pseudoaneurysm was still necessary because of further compression of the airway stem. All immediately treated TBD patients were also successful. However, in 8 of 13 TBD patients with delayed treatment (61.5%), a stent graft deployment was not possible because of complicated progression of the false lumen and multiple intimal entry tears: 1 patient benefited by fenestrations of the false lumen and 7 patients underwent medical therapy. One patient (8.3%) died because of retrograde dissection involving the aortic arch. All patients treated with endovascular stent grafts were discharged within 5 days. Conclusions An immediate endovascular management of PAP and TBD patients offers important advantages such as avoidance of high-risk surgical procedures and postoperative complications with short hospital stay. Moreover, it has been observed that an immediate endovascular treatment allows a safe management of all patients with complete healing of the aortic wall and regression of the pseudoaneurysm in the PAP group and thrombosis of the false lumen in TBD patients
