Results of transcatheter aortic valve implantation (TAVI) for treatment of severe noncalcific isolated aortic regurgitation (AR) complicated by advanced heart failure or cardiogenic shock has been previously reported only in isolated case reports. Current self-expanding transcatheter aortic valves are designed to treat aortic valve stenosis, and have also been implanted in cases of severe AR due to degenerated bioprosthesis and in very few cases of native aortic valves. We report 13 consecutive inoperable patients with noncalcific, pure AR, and advanced heart failure treated with emergency percutaneous transfemoral implantation with self-expandable CoreValves at our institution between July 2012 and September 2017...

OBJECTIVES: The aim of this study was to investigate whether balloon-expandable and self-expandable transcatheter heart valves (THVs) differ in terms of the incidence of early subclinical leaflet thrombosis (LT). METHODS: Electrocardiographic-gated cardiac dual-source computed tomography angiography was performed at a median of 5 days after transcatheter aortic valve implantation and assessed for evidence of LT. RESULTS: Of the 629 consecutive patients, 538 (86%) received a balloon-expandable THV and 91 (14%) a self-expandable THV...

BACKGROUND: This analysis evaluates the relationship of annular size to hemodynamics and the incidence of prosthesis-patient mismatch (PPM) in surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) patients. METHODS: The CoreValve US Pivotal High Risk Trial, described previously, compared TAVR using a self-expanding valve with SAVR. Multislice computed tomography was used to categorize TAVR and SAVR subjects according to annular perimeter-derived diameter: large (≥26 mm), medium (23 to <26 mm), and small (<23 mm)...

BACKGROUND: Although next-generation cardiac prostheses have shown favorable results in transcatheter aortic valve implantation (TAVI), these have mostly been documented in intermediate-risk patients. Whether this could be translated to high-risk patients is not known. Hence, the safety and clinical performance of the new, repositionable CoreValve Evolut R-System (ERS) was evaluated by comparison with a non-repositionable CoreValve-System (CVS), in 96 high-risk/inoperable (HRI) patients...

Sutureless aortic bioprostheses (SAB) provide shorter aortic cross-clamp time and cardiopulmonary bypass duration compared to conventional aortic valve replacement. Similarly to other bioprostheses, reintervention may become necessary in some cases because of long-term structural degeneration of the valve. Valve-in-valve (ViV) transcatheter aortic valve replacement may represent an effective and safe alternative to aortic valve replacement in patients with degenerated bioprostheses who carry a high risk for reintervention...

Importance: Transcatheter aortic valve replacement (TAVR) is established for selected patients with severe aortic stenosis. However, limitations such as suboptimal deployment, conduction disturbances, and paravalvular leak occur. Objective: To evaluate if a mechanically expanded valve (MEV) is noninferior to an approved self-expanding valve (SEV) in high-risk patients with aortic stenosis undergoing TAVR. Design, Setting, and Participants: The REPRISE III trial was conducted in 912 patients with high or extreme risk and severe, symptomatic aortic stenosis at 55 centers in North America, Europe, and Australia between September 22, 2014, and December 24, 2015, with final follow-up on March 8, 2017...

Transcatheter aortic valve replacement (TAVR) has been approved in the United States for intermediate and high-risk patients with severe symptomatic aortic stenosis. More than 80 000 TAVR procedures have been performed in the United States and the number is growing every year. Two valve designs are approved in the United States including the balloon expandable Edwards Sapien prosthesis and self-expanding CoreValve prosthesis. The PARTNER trial of the Sapien valve, involving patients who were considered inoperable, reported a 19% absolute risk reduction in mortality compared with medical therapy, with a number needed to treat of 5...

A 78-year-old man with a history of open sigmoidectomy for sigmoid cancer presented with abdominal pain and vomiting. Abdominal multi-detector CT revealed an obstructive ileocecal tumor with distended small bowel on the oral side. We performed emergency drainage using a transnasal decompression tube, and 2 days later, we conducted a colonoscopic examination, which lead to a provisional diagnosis of obstruction with a malignant tumor invading the ileocecal valve. We then placed a self-expanding metallic stent (SEMS) through the ileocecal valve...

OBJECTIVES: Transcatheter heart valves such as the self-expandable Portico valve (St. Jude Medical) are being developed to overcome limitations of first-generation devices. Since clinical experience with this valve is still limited in a real-world setting, we investigated its use on an all-comer basis. METHODS: Between October 2015 and October 2016, a total of 100 consecutive patients assessed for transcatheter aortic valve replacement (TAVR) and found suitable for the Portico valve were included...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is increasingly being offered to high-risk patients with symptomatic aortic valve stenosis. Recent reports have suggested a high incidence of subclinical leaflet thrombosis following bioprosthestic aortic valve replacement. We report the frequency and clinical presentation of leaflet thrombosis identified by cardiac CT in patients referred for follow-up contrast enhanced CT angiography following TAVI. METHODS: 91 consecutive patients referred for follow-up contrast-enhanced CT angiography following TAVI were screened for inclusion in this analysis...

Procedural complications following transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) are usually reported as retrospective analyses. We report the first comparison of complications following SAVR or self-expanding TAVR from a prospectively randomized study of high-risk SAVR patients. Three hundred ninety-five TAVR and 402 SAVR patients were prospectively enrolled and randomized 1:1 to TAVR with a CoreValve bioprosthesis or a surgical bioprosthetic valve. The rates of major procedural and vascular complications occurring (periprocedurally (0-3 days) and early (4-30 days)) were compared for TAVR vs SAVR patients...

INTRODUCTION AND OBJECTIVES: The SAPIEN 3 (S3) valve and the Medtronic Evolut R (EVR) are second-generation transcatheter valves, designed to further reduce the rate of paravalvular aortic regurgitation (AoR). The aim of this study was to compare the 2 devices in terms of valve performance in a case-matched study with independent echocardiographic analysis. METHODS: Of a population of 201 patients who underwent transcatheter aortic valve implantation, 144 patients (S3, n = 80; EVR, n = 64) were matched according to aortic annulus diameter and aortic valve calcium score, as assessed by computed tomography...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) using a self-expanding valve has been shown to be superior to an open operation in high-risk patients. Extensive iliofemoral peripheral vascular disease can prohibit femoral access. In these cases, direct aortic (DA) implantation may be a suitable option. METHODS: The current analysis compared outcomes in patients undergoing TAVR with the self-expanding CoreValve prosthesis (Medtronic, Minneapolis, MN) by direct aortic (DA) access vs iliofemoral (IF) access...

OBJECTIVES: Transcatheter aortic valve replacement (TAVR) is used increasingly to treat bioprosthetic valve failure. A paucity of data exists regarding valve-in-valve (ViV) TAVR in degenerated Freestyle stentless bioprostheses (FSB). This study sought to evaluate the feasibility and short-term outcomes of ViV TAVR in previously placed FSB. METHODS: From October 2014 to September 2016, 22 patients underwent ViV TAVR with a self-expanding transcatheter valve for a failing FSB at a single institution...

Although occlusion of the coronary arteries during transcatheter aortic valve replacement is rare, the mortality is high. In this review, we discuss the prevention and management of this complication. Occlusion of coronary ostia is a very rare, but serious, complication of transcatheter aortic valve replacement (TAVR). Although reported as only occurring in <1% of TAVR cases, it carries a high risk of fatality, with some series reporting a mortality rate as high as 40%. We present the management of an occluded left coronary artery after a self-expanding TAVR, and review the incidence, prevention, and management of this complication...

OBJECTIVES: We sought to assess angiographic, echocardiographic and hemodynamic grading of paravalvular leakage (PVL) after transcatheter aortic valve implantation (TAVI) with respect to prediction of 1-year mortality. BACKGROUND: Meaningful criteria for the severity of PVL are needed to allow intraprocedural guidance and patient management after TAVI. METHODS: We pooled the prospective TAVI databases of 2 German centers. During TAVI, PVL was assessed angiographically and by the aortic regurgitation index (ARI)...

OBJECTIVES: Compare final morphology of self-expanding and balloon-expandable prosthesis and association with paravalvular regurgitation (PVR). BACKGROUND: PVR after transcatheter aortic valve replacement (TAVR) remains a frequent complication. A better understanding of the prosthesis geometry may be important to improve selection of the best device for each case and possibly reduce the rates of PVR. METHODS: Retrospective study including patients consecutively submitted to transcatheter aortic valve replacement: August/2007-October/2016...
