As transcatheter techniques expand to younger patients, cardiac surgeons need to know a safe surgical technique to extract these kinds of prostheses. We describe here an adequate surgical strategy for the explantation of a CoreValve prosthesis that was implanted more than 5 years previously.

OBJECTIVES: This study evaluated the safety and effectiveness of self-expanding transcatheter aortic valve replacement (TAVR) in patients with surgical valve failure (SVF). BACKGROUND: Self-expanding TAVR is superior to medical therapy for patients with severe native aortic valve stenosis at increased surgical risk. METHODS: The CoreValve U.S. Expanded Use Study was a prospective, nonrandomized study that enrolled 233 patients with symptomatic SVF who were deemed unsuitable for reoperation...

Background Transcatheter aortic valve implantation has been established as a safe and effective treatment option for patients at high or prohibitive surgical risk. However, some patients may not be suitable for the transfemoral approach due to severe iliofemoral disease or aneurysmal disease of the thoracoabdominal aorta. The aim of this case series was to evaluate the feasibility and clinical outcomes of the transaortic approach. Methods From May 2015 to June 2016, 5 patients (mean age 78.4 ± 3.9 years) with severe symptomatic aortic stenosis underwent transaortic transcatheter aortic valve implantation after a heart team discussion...

OBJECTIVES: To evaluate balloon-expandable and self-expanding third-generation transcatheter aortic valve replacement (TAVR) devices according to patient selection criteria and outcomes. BACKGROUND: Two competing third-generation TAVR technologies are currently commercially available in the US. There are no published head-to-head comparisons of the relative performance of these two devices. METHODS: 257 consecutive patients undergoing TAVR with a third-generation balloon-expandable (Edwards Sapien 3) or self-expanding device (Medtronic CoreValve Evolut R) at a single US medical center were included...

BACKGROUND: Extensive evidence relating to transcatheter aortic valve replacement (TAVR) has accumulated in recent years, but mid-term outcomes are less reported. We investigated 996 patients after implantation of the CoreValve prosthesis for severe aortic stenosis in a real-world setting. OBJECTIVE: To report clinical and echocardiographic 3-year results from the ADVANCE study. METHODS: ADVANCE is a prospective, multicenter, fully monitored, nonrandomized clinical study...

: We describe the first reported case of a nose cone entrapment of the delivering catheter of a CoreValve self-expandable valve, during a transcatheter aortic valve implantation procedure. The complication was successfully treated after snaring the cone and retracting the system within the introducing sheath.

Aims: To determine the impact of permanent cardiac pacing after transcatheter aortic valve implantation (TAVI) with the CoreValveTM prosthesis in terms of all-cause mortality and morbidity [rehospitalizations for heart failure (HF) or stroke] at the long-term follow-up. Methods and results: The prospective analysis comprised 259 patients (138 women, 53.3%, age 78 ± 6 years) treated by a CoreValveTM prosthesis from April 2008 to December 2015. Forty-two patients were excluded for analysis: 9 with pre-existing permanent pacemaker (PPM) implantation, 19 who required a PPM during the follow-up and 14 patients because of hospital mortality during or after the CoreValveTM prosthesis implantation procedure...

BACKGROUND: The threshold for the optimal computed tomography (CT) number in Hounsfield Units (HU) to quantify aortic valvular calcium on contrast-enhanced scans has not been standardized. Our aim was to find the most accurate threshold to predict paravalvular regurgitation (PVR) after transcatheter aortic valve replacement (TAVR). METHODS: 104 patients who underwent TAVR with the CoreValve prosthesis were studied retrospectively. Luminal attenuation (LA) in HU was measured at the level of the aortic annulus...

BACKGROUND: Transcarotid access is an alternative route for transcutaneous aortic valve implantation (TAVI) in patients with impossible transfemoral access. AIMS: We evaluated the safety, effectiveness and early and late clinical outcomes of CoreValve(®) implantation via the common carotid artery. METHODS: Eighteen patients (10 men, 8 women; mean age 84±5 years) at high surgical risk (mean EuroSCORE II 16±13%) with significant peripheral artery disease underwent TAVI via common carotid artery access under general anaesthesia...

OBJECTIVE: Valve-in-valve procedures using transcatheter aortic valves are increasingly performed to treat degenerated bioprosthetic surgical aortic valves because they are less invasive than redo aortic valve replacement. The objective of this study is to quantify the changes in aortic sinus blood flow dynamics before and after a valve-in-valve procedure to gain insight into mechanisms for clinical and subclinical thrombosis of leaflets. METHODS: A detailed description of the sinus hemodynamics for valve-in-valve implantation was performed in vitro...

BACKGROUND: The causes of procedural deaths after transcatheter aortic valve implantation (TAVI) have been scarcely detailed. AIMS: To assess these causes and their temporal trends since the beginning of the TAVI era. METHODS: From October 2006 to April 2014, 601 consecutive high-risk/inoperable patients with severe aortic stenosis underwent TAVI using the Edwards SAPIEN or SAPIEN XT or the Medtronic CoreValve. The transfemoral route was the default approach; the transapical or left subclavian approaches were alternative options...

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...

Aims: Paravalvular aortic leakage (PVL) after transcatheter aortic valve implantation (TAVI) is a complication with potentially severe consequences. The relation between native aortic root calcium burden, stent frame eccentricity and PVL was not studied before. Methods and results: Two-hundred-and-twenty-three consecutive patients with severe aortic stenosis who underwent TAVI with a Medtronic CoreValve System© and who had available pre-discharge transthoracic echocardiography were studied...

Aims: Transcatheter aortic valve implantation (TAVI) is frequently associated with cardiac conduction defects (CCD) requiring permanent pacemaker implantation (PPI). Although new-onset left bundle branch block (LBBB) is often seen, the rate of progression to severe CCD is unclear. We aimed to find clinical and electrocardiographic (ECG) parameters associated with severe CCD requiring PPI in patients with a new-onset LBBB after TAVI and assess its effect on clinical outcome. Methods and results: All consecutive patients undergoing TAVI who developed a new-onset LBBB were retrospectively analysed...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is being increasingly performed. OBJECTIVES: From the Bicuspid AS TAVR multicenter registry, the procedural and clinical outcomes in patients with bicuspid versus tricuspid AS were compared. METHODS: Outcomes of 561 patients with bicuspid AS and 4,546 patients with tricuspid AS were compared after propensity-score matching assembling 546 pairs of patients with similar baseline characteristics...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been demonstrated to be an effective alternative to surgical aortic valve replacement (SAVR) in patients with aortic stenosis who are deemed high risk or inoperable. Currently, TAVI procedures in China mostly make use of the domestic Venus A-Valve and the CoreValve; however, there is no data on their comparative performance. METHODS: Consecutive patients undergoing TAVI with the aforementioned devices were included...

BACKGROUND: Residual aortic regurgitation (AR) following transcatheter aortic valve replacement (TAVR) is associated with adverse outcome. We sought to evaluate the efficacy and safety of second CoreValve (CV) implantation to treat residual AR following the initial CV deployment. METHODS AND RESULTS: TAVR patients treated with a second CV due to moderate and above residual AR were compared to single device implantation. Valvular function parameters were compared at baseline, post procedure, and 30 days...
