ABSTRACT
PURPOSE: Abdominal aortic aneurysms (AAA) are observed in 6% of patients with concomitant aortic valve stenosis (AS) requiring aortic valve replacement. Optimal management of these concomitant pathologies is still debated. CASE REPORT: An 80-year-old man presented with acute heart failure due to a severe AS. Past medical history included AAA under regular surveillance. A thoracic and abdominal computed tomography angiography (CTA) confirmed a 6 mm increase of AAA over an 8-month period (max 55 mm). A multidisciplinary team prescribed a simultaneous endovascular approach of transcatheter aortic valve implantation (TAVI) followed by endovascular aneurysm repair (EVAR) under local anaesthesia with bilateral femoral percutaneous access. No intra or post-procedural complications were registered; technical success was confirmed by completion angiography and post-operative ultrasound. The patient was discharged on postoperative day 5. A 2-month post-operative CTA confirmed ongoing technical success. CONCLUSION: Combined TAVI and EVAR under local anaesthesia for AS and AAA was associated with reduced hospital stay and technical success at 2 months from intervention in this case report.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has proven over the years to be a viable alternative to open surgery. A rare but severe complication is represented by the valve migration. We report a case of TAVI complication due to the loss of the prosthetic valve in the abdominal aorta treated by endovascular approach. METHODS: An 88-year-old patient with severe aortic valve stenosis, symptomatic for dyspnea was proposed for a TAVI because considered at high risk for surgery. During the TAVI procedure, the undeployed device (Edwards SAPIEN 3 - Edwards Lifesciences, Irvine, CA, USA) detached from its delivery system. Several attempts to withdraw the valve fluctuating in the aorta into its supporting system were performed without success. An emergency endovascular treatment was promptly planned to obtain the exclusion from the flow of the embolized valve. Under local anaesthesia, through the percutaneous femoral access already present, a tube aortic endograft (EndurantTM II, Medtronic, Santa Rosa, CA; ETTF2828C70EE) was successfully introduced and deployed in the infrarenal aorta without any related complications. The embolized valve was completely covered by the endgraft and thus fixed to the aortic wall. The first postoperative computer tomography angiography (CTA) confirmed the correct placement of the endograft, the exclusion of the valve from the flow and the patency of the great vessels. No perioperative or postoperative complications were recorded. The patient was discharged on the ninth postoperative day with the indication to a new attempt of TAVI, through transapical access. CONCLUSIONS: In case of intraprocedural loss of an undeplyed valve during TAVI, the valve fixing through endograft deployment in infrarenal aorta is a possible solution.

BACKGROUND: The service strategy (same-day transfer between spoke hospital and hub centre with catheterisation laboratory (cath-lab) facility to perform invasive procedures) has been suggested to improve the management of patients with non-ST-segment elevation acute coronary syndrome (NSTEACS) admitted to spoke hospitals. We used data from a large prospective Italian registry to describe application, performance and outcome of the service strategy in the daily clinical practice. METHODS: This study was based on an observational, post-hoc analysis of all consecutive NSTEACS patients admitted to spoke non-invasive hospitals of the Emilia-Romagna regional network and receiving coronary artery angiography (CAA)±percutaneous coronary intervention (PCI). We evaluated: application of service strategy, time to cath-lab access, hospital stay length, 30-days occurrence of adverse events. RESULTS: From January 2011-December 2012, 2952 NSTEACS consecutive patients were admitted to spoke non-invasive hospitals and received CAA. Overall, 1765 (60%) patients were managed with a service strategy. After multivariable analysis, service strategy emerged as independent predictor of faster access to cath-lab (within 72 h: hazard ratio (HR) 2.3, 95% confidence interval (CI) 1.9-2.7, p<0.0001; within 24 h: HR 2.8, 95% CI 2.2-3.3, p<0.0001, respectively). Service strategy significantly reduced hospital stay length (-5.5 days, p<0.0001). We estimated a mean of 1590 saved for each patient managed with service strategy. Thirty-day occurrence of adverse events did not differ between patients managed with or without a service strategy. CONCLUSIONS: In our daily clinical practice, a service strategy seems to be an effective approach to optimise the invasive management of NSTEACS patients admitted to spoke hospitals.
