Transcatheter aortic valve implantation (TAVI) is the treatment of choice in patients with symptomatic severe aortic stenosis who are either inoperable or at high risk for conventional surgical aortic valve replacement. Recent data have also shown favourable outcomes in patients deemed to be at intermediate operative risk, which expands the application of this novel technology. Despite its success, TAVI has been associated with rare life-threatening complications. Of these, aortic annular rupture is considered to be the most devastating. Advances in pre-procedural screening and patient selection have reduced the incidence of annular rupture. When this complication occurs, early recognition and prompt management are essential. This article is intended to provide a comprehensive review of the predictors, management and clinical outcomes of aortic annular rupture.

Abstract Aims  Owing to new evidence from randomized controlled trials (RCTs) in low-risk patients with severe aortic stenosis, we compared the collective safety and efficacy of transcatheter aortic valve implantation (TAVI) vs. surgical aortic valve replacement (SAVR) across the entire spectrum of surgical risk patients. Methods and results  The meta-analysis is registered with PROSPERO (CRD42016037273). We identified RCTs comparing TAVI with SAVR in patients with severe aortic stenosis reporting at different follow-up periods. We extracted trial, patient, intervention, and outcome characteristics following predefined criteria. The primary outcome was all-cause mortality up to 2 years for the main analysis. Seven trials that randomly assigned 8020 participants to TAVI (4014 patients) and SAVR (4006 patients) were included. The combined mean STS score in the TAVI arm was 9.4%, 5.1%, and 2.0% for high-, intermediate-, and low surgical risk trials, respectively. Transcatheter aortic valve implantation was associated with a significant reduction of all-cause mortality compared to SAVR {hazard ratio [HR] 0.88 [95% confidence interval (CI) 0.78–0.99], P = 0.030}; an effect that was consistent across the entire spectrum of surgical risk (P-for-interaction = 0.410) and irrespective of type of transcatheter heart valve (THV) system (P-for-interaction = 0.674). Transcatheter aortic valve implantation resulted in lower risk of strokes [HR 0.81 (95% CI 0.68–0.98), P = 0.028]. Surgical aortic valve replacement was associated with a lower risk of major vascular complications [HR 1.99 (95% CI 1.34–2.93), P = 0.001] and permanent pacemaker implantations [HR 2.27 (95% CI 1.47–3.64), P < 0.001] compared to TAVI. Conclusion  Compared with SAVR, TAVI is associated with reduction in all-cause mortality and stroke up to 2 years irrespective of baseline surgical risk and type of THV system.

Severe aortic stenosis (AS) and mitral regurgitation (MR) are the two most common valvular lesions referred for surgical intervention in Europe and frequently co-exist. In patients with both severe AS and significant MR referred for surgical aortic valve replacement (SAVR), a concomitant mitral valve intervention is typically performed if the MR is severe, despite the higher associated perioperative risk. The management of moderate MR among SAVR patients is controversial and depends on a number of factors including MR aetiology (i.e., organic versus functional MR), feasibility of repair and patient risk profile. Moderate or severe MR is present in up to one-third of patients undergoing transcatheter aortic valve implantation (TAVI), is mainly of functional aetiology and is typically left untreated. Although data are conflicting, a growing body of evidence suggests that significant MR exerts an adverse effect on both short- and long-term clinical outcomes after TAVI. Moderate or severe MR improves in just over half of patients following TAVI and recent data suggest MR is more likely to improve among patients receiving a balloon-expandable as compared with a self-expandable transcatheter heart valve.

Valve Implantation

Transcatheter aortic valve implantation (TAVI) is the usual technique for patients with severe aortic stenosis who are at high risk for surgical aortic valve replacement. The transfemoral (TF) route is the most commonly used access type, and significant progress in this procedure has greatly increased the proportion of patients who can undergo it. Not all patients are suitable for TF TAVI, however, so other routes, including transapical, transaortic, subclavian, trans-subclavian/transaxillary, transcarotid and transcaval, may need to be used. Evidence on these routes shows promising results but the majority of this is registry data rather than randomised controlled trials, so TF TAVI remains the safest access route and should be considered for most patients. However, in patients who are unsuitable for TF TAVI, alternative access routes are safe and feasible. The challenges concern choosing the best route, the valve to use and skill of the specialist centre. This article provides a overview of options for alternative vascular access in TAVI, the clinical rationale for using them, current evidence and areas for clinical investigation.

Abstract Transcatheter aortic valve implantation has become a valid alternative to surgical aortic valve replacement for patients with symptomatic severe aortic stenosis, regardless of baseline surgical risk. The incidence of periprocedural complications has steadily declined over the years, thanks to technical advancement of transcatheter heart valves, delivery systems, and increased operators’ experience. Beyond the most common periprocedural complications, there are a few uncommon but potentially severe complications that more often occur during follow-up, although they may also arise in the periprocedural phase. Stroke, infective endocarditis, valve thrombosis, and cognitive decline are among them. In this brief review, we describe the incidence, predictive factors, and potential preventive measures for those events.

Transcatheter aortic valve implantation (TAVI) has become a standard treatment for severe aortic stenosis. Although this technique has reached relative maturity, further optimisation of patient selection and device implantation is essential to improve prognosis. Smaller body size is a predictor of a challenging TAVI procedure due to specific anatomical difficulty and adverse events including annulus rupture, acute coronary obstruction and vascular complications. A newer generation, lower profile TAVI system is useful for patients with smaller anatomy. Moreover, TAVI is superior to surgical aortic valve replacement in patients with a narrowing annulus because this treatement has a low incidence of prosthesis�patient mismatch.

Transcatheter aortic valve implantation (TAVI) has become the leading technique for aortic valve replacement in symptomatic patients with severe aortic stenosis with conventional surgical aortic valve replacement (SAVR) now limited to patients younger than 65–75 years due to a combination of unsuitable anatomies (calcified raphae in bicuspid valves, coexistent aneurysm of the ascending aorta) and concerns on the absence of long-term data on TAVI durability. This incredible rise is linked to technological evolutions combined with increased operator experience, which led to procedural refinements and, accordingly, to better outcomes. The article describes the main and newest technical improvements, allowing an extension of the indications (valve-in-valve procedures, intravascular lithotripsy for severely calcified iliac vessels), and a reduction of complications (stroke, pacemaker implantation, aortic regurgitation).

Abstract Background Valve-in-valve transcatheter aortic valve implantation (TAVI) has emerged as a competent alternative for the treatment of degenerated bioprosthetic valves after surgical aortic valve replacement, or during TAVI procedure as a bailout option. Herein, we report a rare case of a self-expandable Medtronic Evolut R valve into a failing Medtronic CoreValve, with the use of modern pre-TAVI imaging screening, suggesting the proper procedural design steps for so complicated implantations. Case summary A frail 78-year-old woman with a degenerated Medtronic Core Valve 26 mm bioprosthesis, implanted in 2011 due to severe aortic stenosis, was referred to our hospital due to worsening dyspnoea New York Heart Association III. The screening echocardiography documented severe aortic stenosis, while the classical risk scores were in favour of repeated TAVI (EuroSCORE II 5.67%). Computed tomography measurements and three-dimensional (3D) printing model were of great help for the proper valve selection (Medtronic Evolut R 26 mm), while the use of cerebral protection device (Claret Sentinel) was considered as a necessary part of the procedure. The simultaneous use of fluoroscopy and transoesophageal echocardiogram led to optimal haemodynamic result, confirmed by the discharge echocardiogram, with a significant clinical improvement during the first month follow-up. Discussion The main periprocedural concerns remain valve malpositioning, coronary artery obstruction, and high remaining transvalvular gradients. The multimodality pre-TAVI imaging screening may be helpful for precise procedural design. Despite the limited use of 3D models, it is necessary to adopt such tissue-mimicking phantoms to increase the possibility of optimal procedural result.
