Transcatheter valve-in-valve implantation (ViV-TAVI) has evolved as an alternative to redo surgical valve replacement (redo-SAVR) for high-risk patients with aortic bioprosthetic valve (BPV) dysfunction. The differences in procedural success and outcomes in a large number of patients who underwent ViV-TAVI compared with redo-SAVR for aortic BPV dysfunction are not known. We conducted a meta-analysis of the previously reported studies to determine outcomes after ViV-TAVI and redo-SAVR. PubMed, MEDLINE, and Google Scholar databases were searched for studies that reported comparative outcomes of patients who underwent either ViV-TAVI or redo-SAVR...

Mitroflow aortic prosthesis dysfunction in case of complex vascular disease is considered a challenging scenario. Because of the high risk for surgical reoperation and the presence of chronic aortic dissection originated from a calcified Kommerel diverticulum, we considered to perform a transapical valve-in-valve transcatheter aortic valve implantation (TAVI) procedure. Myocardial ischemia is a dreadful complication reported in valve-in-valve TAVI procedures, mainly in patients with degenerated Mitroflow aortic bioprostheses...

BACKGROUND: The extent of aortic valve calcification is an important determinant of procedural success in transcatheter aortic valve implantation (TAVI). We sought to validate device landing zone calcium volume (DLZ-CV) measurements on contrast-enhanced multidetector computed tomography (MDCT) with non-contrast-enhanced scans as reference. METHODS: We determined DLZ-CV in 141 patients undergoing transfemoral TAVI. Non-contrast-enhanced images were analyzed using a threshold of 130 HU as reference (DLZ-CV130 )...

AIMS: Long-term results of transcatheter aortic valve implantation (TAVI), in particular the incidence of bioprosthetic valve failure (BVF), are uncertain. METHODS AND RESULTS: The study prospectively included all 152 patients who had undergone TAVI with the self-expanding CoreValve™ up to December 2011 at the Heart Center, Bad Segeberg, Germany. Late BVF (>30 days) was defined as either: 1) Severe structural valve deterioration (trans-prosthetic mean pressure gradient ≥40 mmHg and/or ≥20 mmHg rise from baseline OR severe intra-prosthetic aortic regurgitation), OR 2) Bioprosthetic valve dysfunction leading to death or re-intervention...

Transcatheter aortic valve implantation (TAVI) has been established as a low-invasive therapy for aortic stenosis, but circulatory collapse necessitating mechanical circulatory support could occur during TAVI due to procedure itself or procedural complications. The purpose of this study is to describe the outcomes of patients requiring extracorporeal membrane oxygenation (ECMO) in TAVI. Among 384 consecutive patients undergoing TAVI from April 2010 to July 2017 in Sakakibara Heart Institute, we evaluated seven patients (1...

In year 2016, the American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI) updated Recommendations for the assessment and grading of diastolic dysfunction (DD). We aimed to assess the applicability of this DD grading method and its association with prognosis in patients with severe aortic stenosis (AS) who underwent transcatheter aortic valve implantation (TAVI). We retrospectively identified 237 consecutive patients with severe AS who underwent trans-femoral TAVI...

In the 16 years since the first pioneering procedure, transcatheter aortic valve implantation (TAVI) has come of age and become a routine strategy for aortic valve replacement, increasingly performed under conscious sedation via transfemoral access. Simplification of the procedure, accumulation of clinical experience, and improvements in valve design and delivery systems have led to a dramatic reduction in complication rates. These advances have allowed transition to lower risk populations, and outcome data from the PARTNER 2A and SURTAVI trials have established a clear evidence base for use in intermediate risk patients...

Acute kidney injury (AKI) following transcatheter aortic valve implantation (TAVI) is associated with increased morbidity and mortality. The biomarkers neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and interleukin-18 (IL-18) are predictive of AKI after cardiac surgery, but there is little data regarding these biomarkers after TAVI. We evaluated the associations between NGAL, KIM-1, and IL-18 levels and the incidence and severity of AKI and changes in serum creatinine after TAVI...

Transcatheter aortic valve implantation (TAVI) is indicated in severe symptomatic aortic stenosis, when there is intermediate-high surgical risk, or a condition considered inoperable, as in the case of "porcelain aorta" that could turn clamping or cannulation of the ascending aorta hazardous in open-heart surgery. Among the complications of this less invasive procedure, intraventricular conduction disorders subsequent to the procedure stand out. TAVI causes worsening of intraventricular dromotropic disorders in more than 75% of the cases, with the presence of preexisting right bundle branch block and first-degree atrioventricular block, deep prosthesis implant, male gender, size of the aortic annulus smaller than the prosthesis, and porcelain aorta being predictive of requirement for permanent pacemaker implant...

Interventions focused on ensuring safe transitions for patients from hospital to home can assist in providing continuity of care, preventing readmissions, and reducing duplication of services. Patients undergoing a Transcatheter Aortic Valve Implantation (TAVI) procedure are often frail, elderly, and have multiple co-morbidities. A pilot initiative evaluating transitional care strategies through telephone follow up was implemented in a tertiary centre with the aim to identify gaps and intervene, preventing re-admission and improving patient outcomes...

AIMS: Antithrombotic therapy after transcatheter aortic valve implantation (TAVI) is highly controversial and guideline recommendations are not evidence based. We assessed efficacy and safety of non-vitamin K antagonist oral anticoagulant (NOAC) monotherapy in patients with concomitant indications for OAC undergoing TAVI. METHODS: Among more than 1300 TAVI patients since 2008, 154 patients were identified who received postinterventional NOAC monotherapy. Outcomes were compared to 172 patients treated with vitamin K antagonist (VKA) monotherapy...

Transcatheter aortic valve implantation (TAVI) has become the method of choice for patients with severe aortic valve stenosis, who are ineligible or at high risk for surgery. In this high risk patient population, early and late mortality and rehospitalization rates after TAVI are still relatively high. In spite of recent improvements in procedural TAVI, and establishment of risk models for poor outcome, determining individual risk remains challenging. In this context, current data from several small studies strongly suggest that blood biomarkers of myocardial injury, cardiac mechanical stretch, inflammation, and hemostasis imbalance might play an important role by providing informations on patient risk at baseline, and postprocedural progression of patient clinical conditions from days up to years post-TAVI...

PURPOSE: Transcarotid transcatheter aortic valve implantation (TAVI) is one alternative approach if unfavorable femoral access. However, this approach may cause cerebral vascular accidents (CVAs) by temporarily occluding common carotid artery (CCA). The purpose of this study is to develop a new method reducing cerebral ischemia during transcarotid TAVI. METHODS: We inserted an 8- and 18-Fr. sheath in CCA with tip toward brain and aortic arch, respectively, and connected their side arms to create a bypass flow...

In patients who underwent transcatheter aortic valve implantation (TAVI), postoperative mortality risk is commonly assessed with risk scores such as the Society of Thoracic Surgeons-Postoperative Risk of Mortality (STS-PROM) and EuroSCORE II, in which age plays a dominant role. However, we reason that in the naturally selected oldest-old patients (nonagenarians), this may not be completely justified and that therefore age should play a minor role in decision-making. The objective of this study was to compare procedural outcome and mid-term mortality of transfemoral (TF)-TAVI patients aged ≥90 years with patients aged <90 years...
