Objectives:
We sought to document aortic cusps fluoroscopic projections and their distributions using leaflet alignment which is a novel concept to optimize visualization of leaflets and for guiding BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent coronary artery obstruction) and determine whether these projection...
Background
Eccentricity of coronary ostial positions in relation to the aortic valve cusp may influence the target laceration location in BASILICA (Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Coronary Artery obstruction). Eccentricity of the coronary ostia in relation to coronary cusps of native and valve-in-valve trans...
Objective:
To identify outcomes of patients undergoing emergency transcatheter aortic valve replacement (TAVR) and determine predictors of in-hospital mortality.
Background:
Emergency TAVR has emerged as a viable treatment strategy for patients with decompensated severe aortic stenosis and/or regurgitation; however, data on patients undergoing e...
Coronary obstruction is a life-threatening complication of transcatheter aortic valve replacement. Bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) seems to be an effective approach for preventing coronary obstruction by maintaining blood flow towards the coronary artery by a...
Coronary obstruction is a life-threatening complication of transcatheter aortic valve replacement. BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) seems to be an effective method for preventing that complication. In this article, we describe how to assess patients for their...
Objectives:
We performed a prospective, single-arm clinical trial approved under a Food and Drug Administration Investigational Device Exemption to assess safety and efficacy of Perceval, a sutureless bovine pericardial aortic valve representing the initial US experience.
Methods:
From June 2013 to January 2015, 300 patients (mean age 76.7 ± 7.7...
Objectives:
This study sought to develop a novel technique called bioprosthetic or native aortic scallop intentional laceration to prevent coronary artery obstruction (BASILICA).
Background:
Coronary artery obstruction is a rare but fatal complication of transcatheter aortic valve replacement (TAVR).
Methods:
We lacerated pericardial leaflets...
Bioprostheses are prone to structural valve degeneration, resulting in limited long-term durability. A significant challenge when comparing the durability of different types of bioprostheses is the lack of a standardized terminology for the definition of a degenerated valve. This issue becomes especially important when we try to compare the degener...
Objectives:
The aim of this study was to determine whether the association of small label size of the surgical valve with increased mortality after transcatheter valve-in-valve (ViV) implantation is, at least in part, related to pre-existing prosthesis-patient mismatch (PPM) (i.e., a bioprosthesis that is too small in relation to body size).
Back...
Introduction: Transcatheter mitral valve replacement (TMVR) using aortic transcatheter heart valves (THV) is developing as an alternative to surgery for patients with severely degenerated mitral valve (MV) bioprostheses. Retrospective self-reported registries have collected outcomes on these TMVR procedures in the STS/ACC Transcatheter Valve Therap...
Objectives:
Prosthetic leaflet thrombosis is a growing concern in transcatheter aortic valve replacement (TAVR). Given the uncertainty of best practices for antiplatelet and anticoagulation therapies in the post-TAVR period, additional evidence regarding the impact of anticoagulation on prosthetic valve function after TAVR is needed.
Methods:
Pa...
Objective:
Transcatheter heart valve implantation in failed aortic bioprostheses (valve-in-valve [ViV]) is an increasingly used therapeutic option for high-risk patients. However, high postprocedural gradients are a significant limitation of aortic ViV. Our objective was to evaluate Medtronic CoreValve Evolut R ViV hemodynamics in relation to the...
Internal thoracic arteries (ITAs) should be used to bypass the left anterior descending (LAD) artery when bypass of the LAD is indicated (class of recommendation [COR] I, level of evidence [LOE] B). As an adjunct to left internal thoracic artery (LITA), a second arterial graft (right ITA or radial artery [RA]) should be considered in appropriate pa...
Background:
Previous studies indicated that patients undergoing coronary artery bypass graft (CABG) surgery are less likely to receive guideline-based secondary prevention therapy than are those undergoing percutaneous coronary intervention (PCI) after an acute myocardial infarction. We aimed to evaluate whether these differences have persisted af...
A 74-year-old white man with unstable angina underwent an uneventful urgent four-vessel coronary bypass operation at which time a Tenkhoff catheter was placed because of renal insufficiency. Two hours following arrival in the intensive care unit, the patient demonstrated hemodynamic instability, progressive acidosis, and a fall in his hematocrit fr...
The use of vena caval filters to prevent pulmonary emboli has become routine. Although the complications have been well described, we present the first reported case of perforation of the heart and subsequent cardiac tamponade several months following placement of a Gintureo-Roehm "bird's nest" filter.
