Transcatheter aortic valve implantation - Top 30 Publications

Transcatheter aortic valve implantation compared with surgical aortic valve replacement in patients with anaemia.

We compared the outcome of anaemic patients undergoing transcatheter (TAVI) and surgical aortic valve replacement (SAVR) for severe aortic valve stenosis.

Longitudinal strain assessed by cardiac magnetic resonance correlates to hemodynamic findings in patients with severe aortic stenosis and predicts positive remodeling after transcatheter aortic valve replacement.

Impact of diabetes mellitus on clinical outcomes and quality of life after transcatheter aortic valve implantation for severe aortic valve stenosis.

Diabetes mellitus (DM) has been considered as a marker of poor prognosis after cardiac surgery. We sought to investigate the impact of DM on clinical outcomes and quality of life (QoL) after transcatheter aortic valve implantation (TAVI).

Quality and Safety in Health Care, Part XXX: Transcatheter Aortic Valve Therapy.

Initially, the transcatheter aortic valve replacement procedure was approved only for patients with aortic stenosis that was both severe and symptomatic who either also had too high a risk of aortic valve replacement surgery to have the surgery or who had a high risk for the surgery. Between the years 2012 and 2015, the death rate at 30 days declined from an initial rate of 7.5% to 4.6%. There has also been more use of the transfemoral approach over the years. In 2016, the transcatheter aortic valve replacement was approved for patients with aortic stenosis at intermediate risk of surgery.

Quality and Safety in Health Care, Part XXXI: Selected Risk Factors for Transcatheter Aortic Valve Replacement.

The Transcatheter Valve Therapy Registry has been very helpful in providing data to better understand patient risk factors for transcatheter aortic valve replacement (TAVR). The outcome of TAVR depends on many patient indicators, some of which are given in this article, including the age, dependence on oxygen, classification of pulmonary disease, gender, and the speed of walking. Patient characteristics also help determine which approach will be used to place the device. There are models for the outcome of the TAVR procedure now and more being developed.

Outcomes of Transcatheter Versus Surgical Aortic Valve Implantation for Aortic Stenosis in Patients With Hepatic Cirrhosis.

Current risk prediction tools for transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) do not include variables associated with clinically significant hepatic disease. Accordingly, outcome data of TAVI or SAVR in patients with liver cirrhosis are limited. We sought to assess contemporary trends and outcomes of TAVI and SAVR in patients with liver cirrhosis using a national database. The Nationwide Inpatient Sample was used to identify patients with liver cirrhosis who underwent TAVI or SAVR between 2003 and 2014. Outcomes of propensity-matched groups of patients undergoing TAVI or SAVR were assessed. The reported number of TAVI and SAVR procedures in patients with liver cirrhosis increased from 376 cases in 2003 to 1,095 cases in 2014. A total of 1,766 patients with liver cirrhosis who underwent TAVI (n = 174) or SAVR (n = 1,592) were included in the analysis. In-hospital mortality was higher in patients who underwent SAVR versus TAVI (20.2% vs 8%, p <0.001). Major adverse events were also more frequent after SAVR. Propensity matching attained 2 groups of 268 patients who underwent TAVI (n = 134) or SAVR (n = 134). Following propensity matching, in-hospital mortality remained higher in the SAVR group (18.7% vs 8.2%, p = 0.018), but major adverse events were not different between the 2 groups. Hospital length of stay was longer, and nonhome disposition rates were higher in the SAVR group. In conclusion, the number of reported TAVI and SAVR in patients with liver cirrhosis and aortic stenosis increased 3-folds between 2003 and 2014. In these patients, TAVI was associated with lower in-hospital mortality when compared with SAVR.

Emergent TAVR During TEVAR.

Utility of the guideliner catheter for percutaneous coronary interventions in patients with prior transcatheter aortic valve replacement.

The safety and utility of GuideLiner catheters in complex percutaneous coronary interventions (PCI) has been well established. Patients with prior trans-catheter aortic valve replacement especially with CoreValve, who present for PCI, pose a unique set of challenges. Not only does the operator often encounter difficulty with selective engagement of coronary ostia through the struts of the CoreValve, but also the complex nature of the underlying CAD in this high-risk population. We present a case series to illustrate the use of GuideLiner catheter as an adjunctive tool for PCI in this patient population.

Hospital teaching status and trascatheter aortic valve replacement outcomes in the United States: Analysis of the national inpatient sample.

Evidence suggests that medical service offerings vary by hospital teaching status. However, little is known about how these translate to patient outcomes. We therefore sought to evaluate this gap in knowledge in patients undergoing Transcatheter aortic valve replacement (TAVR) in the United States.

Low-Flow Severe Aortic Stenosis: Evolving Role of Transcatheter Aortic Valve Replacement.

The definition of severe aortic stenosis has classically and retrospectively been based on the natural history of patients with medically managed aortic stenosis and preserved left ventricular function in an era where surgical aortic valve replacement was the sole therapy. We now recognize that this disease is more heterogeneous and includes important subsets of patients with low stroke volume index (low flow) and low-gradient with reduced (classical) or preserved (paradoxical) ejection fraction. These patients pose diagnostic and treatment dilemmas, requiring a comprehensive assessment with integration of multimodality imaging, testing, and clinical assessment. Surgery in these patients has been associated with higher operative mortality and lower long-term survival. Transcatheter aortic valve replacement (TAVR), because of its less-invasive nature, avoidance of the detrimental effects of cardiopulmonary bypass, and larger effective orifice area, offers several potential advantages. Studies of TAVR in low-flow severe aortic stenosis patients have demonstrated that TAVR has a significant mortality benefit compared with medical therapy and a similar benefit compared with surgery. Both low flow and low ejection fraction have emerged as important factors in predicting mortality post-TAVR, with particularly poor survival when flow or ejection fraction fail to improve. The recognition, diagnosis, and treatment of patients with low-flow severe aortic stenosis remains challenging. It is likely that TAVR will play an increasingly important role in the management of these patients.

Predictors of cerebrovascular events at mid-term after transcatheter aortic valve implantation - Results from EVERY-TAVI registry.

Clinical relevant cerebrovascular events (CVE) following transcatheter aortic valve implantation (TAVI) still remain a devastating complication associated with mortality and severe impairments. Therefore, identification of particularly modifiable predictors of this complication is clinically relevant and an important step for planning preventive strategies.
