BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. METHODS: From July 2008 to May 2015, 856 transcatheter heart valves were implanted at our center (age: 80...

OBJECTIVES: The aim of this study was to evaluate the short-term safety and performance of the full range of valve sizes offered within the Portico transcatheter aortic valve replacement system. BACKGROUND: The Portico transcatheter aortic heart valve is a fully resheathable, repositionable, and self-expanding bioprosthesis designed to achieve optimal valve position and hemodynamic performance and limit conduction disturbances. METHODS: Patients (n = 222) with symptomatic (New York Heart Association functional class ≥II) severe aortic stenosis considered by a multidisciplinary heart team to be at high surgical risk were recruited between December 2011 and September 2015 in this prospective, nonrandomized, multicenter study...

OBJECTIVE: The aim of this study was to conduct a weighted meta-analysis to determine the rates of acute (≤30days) major outcomes after (TAVR) with second-generation devices. METHODS: A comprehensive search of multiple electronic databases from January 2011 to May 2017 was conducted using predefined criteria. New-generation TAVR devices were defined as any device which received CE mark approval or is still under evaluation for CE marking after CoreValve and SAPIEN XT prostheses...

Although the rate of procedural complications during transcatheter aortic valve implantation has decreased because of technological advancement and increased operator experience, device embolization remains a rare but potentially fatal complication, even with new generation devices. We report, to our knowledge, the first case of Portico valve (St Jude Medical, Minneapolis, MN) migration despite apparent optimal initial implantation depth, which was retrieved using a novel strategy after failure of a traditional retrieval technique...

BACKGROUND: Feasibility of transfemoral (TF) transcathteter aortic valve replacement (TAVR) is limited by the smallest diameter, the calcification and tortuosity of the iliofemoral access vessels. The use of the Portico system without delivery sheath results in significantly lower profile delivery system compared to standard technique. We herein report our single center experience, feasibility and safety of such an approach. METHODS: The Portico valve was implanted sheathless in 81 high-risk patients with severe aortic stenosis utilizing percutaneous femoral access...

BACKGROUND: Transcatheter valve-in-valve implantation is an established therapy for high-risk patients with failed surgical aortic bioprosthesis. There are limited data comparing outcomes of valve-in-valve implantation using different transcatheter heart valves (THV). METHODS AND RESULTS: Patients included in the Valve-in-Valve International Data registry (VIVID) and treated with self-expanding THV devices were analyzed using centralized core laboratory blinded to clinical events...

Subclinical leaflet thrombosis was recently described in a randomized trial of transcatheter aortic valve replacement. It was subsequently demonstrated in a series of registries that this was a commonly observed imaging finding seen in all transcatheter and surgical bioprostheses. The phenomenon has aroused considerable interest due to the as-yet-undefined risk for later clinical events and the possibility of pharmacological intervention with anticoagulation. Subclinical leaflet thrombosis is easily detected noninvasively by technically suitable computed tomography (CT) with a high degree of concordance to transesophageal echocardiography findings...

Transcatheter aortic valve implantation (TAVI) has become an important treatment in high surgical risk patients with severe aortic stenosis (AS), whose complications need to be managed promptly. The authors report the case of an 86-year-old woman presenting with severe symptomatic AS, rejected for surgery due to advanced age and comorbidities. The patient underwent a first TAVI, with implantation of a Medtronic CoreValve(®), which became dislodged and migrated to the ascending aorta. Due to the previous balloon valvuloplasty, the patient's AS became moderate, and her symptoms improved...

Transcatheter aortic valve implantation has been designed to treat older patients affected by severe aortic stenosis who are considered high-risk surgical candidates because of multiple comorbidities. The least invasive approach for transcatheter aortic valves implantation should be considered the transfemoral retrograde route, because it is minimally invasive and is feasible with local anesthesia and mild sedation. Despite significant technical improvements in recent years, the transfemoral approach is contraindicated in cases of severe peripheral artery disease...

AIMS: The aim of this study was to examine the short- and medium-term outcomes of transcatheter aortic valve replacement (TAVR) with the self-expanding and repositionable Portico valve (St. Jude Medical, St. Paul, MN, USA). METHODS AND RESULTS: A total of 57 patients underwent TAVR with the Portico valve between March 2012 and August 2014, representing the first-in-human experience and the entire early experience in Canada. Patients were followed up at 30 days and one year with repeat echocardiography and clinical review...

AIMS: Transcatheter heart valve (THV) implantation in failed bioprosthetic valves (valve-in-valve [ViV]) offers an alternative therapy for high-risk patients. Elevated post-procedural gradients are a significant limitation of aortic ViV. Our objective was to assess the relationship between depth of implantation and haemodynamics. METHODS AND RESULTS: Commercially available THVs used for ViV were included in the analysis (CoreValve Evolut, SAPIEN XT and the Portico valve)...

BACKGROUND: Transcatheter aortic valves can degenerate in a manner similar to surgical bioprostheses. METHODS AND RESULTS: Clinical and echocardiographic outcomes of patients who underwent redo transcatheter aortic valve replacement (TAVR) procedures >2 weeks post procedure were collected from 14 centers. Among 13 876 patients, 50 (0.4%) underwent redo TAVR procedure at participating centers. Indications for redo TAVR were moderate-severe prosthetic aortic valve stenosis (n=10, 21...

The Portico system (St. Jude Medical, Minneapolis, MN, USA) consists of a self-expanding valve prosthesis and a delivery system designed for transcatheter aortic valve replacement (TAVR). We describe this system, its 10-steps implantation procedure, and provide tips and tricks based on our personal experience with this system.

In the last years, a general shift toward the use of surgical bioprosthetic aortic valves rather than mechanical valves with subsequent less use of anticoagulant therapy has been observed. However, bioprosthetic valves have limited durability. Reoperation, the current standard of care for these patients, carries a high surgical risk, especially because patients are elderly and with numerous comorbidities. Recently, transcatheter aortic valve replacement within a failed bioprosthetic valve (valve-in-valve procedure) has proven feasible...

BACKGROUND: A finding of reduced aortic-valve leaflet motion was noted on computed tomography (CT) in a patient who had a stroke after transcatheter aortic-valve replacement (TAVR) during an ongoing clinical trial. This finding raised a concern about possible subclinical leaflet thrombosis and prompted further investigation. METHODS: We analyzed data obtained from 55 patients in a clinical trial of TAVR and from two single-center registries that included 132 patients who were undergoing either TAVR or surgical aortic-valve bioprosthesis implantation...

OBJECTIVE: Since the beginning of the transcatheter aortic valve implantation (TAVI) era, many prosthetic valves have entered clinical practice. TAVI prostheses differ regarding stent design and some may potentially interfere with diagnostic or interventional catheters. The aim of our analysis was to evaluate the feasibility of coronary angiography (CA) or percutaneous coronary intervention (PCI) in patients with prior TAVI. METHODS: From 2011 to 2014, 1,000 patients were treated by TAVI at our center using eight different valve prostheses (Symetis ACURATE TA and ACURATE TF; Medtronic CoreValve and Engager; JenaValve, SJM Portico; Edwards Lifesciences SAPIEN and SAPIEN XT)...
