Background: The 2020 European Society of Cardiology (ESC) guidelines recommend using the 0/1-hour and 0/2-hour algorithms over the 0/3-hour algorithm as the first and second choices of high-sensitivity cardiac troponin (hs-cTn)-based strategies for triage of patients with suspected acute myocardial infarction (AMI).
Purpose: To evaluate the diagnostic accuracies of the ESC 0/1-hour, 0/2-hour, and 0/3-hour algorithms.

The presence of left atrial thrombus is a contraindication to cardioversion or catheter ablation in patients with atrial fibrillation, due to the increased risk of systemic thromboembolism. Management of this situation includes changes in the anticoagulation regimen and repeat imaging tests. Accurate diagnosis of left atrial appendage thrombus is therefore essential but can sometimes be challenging.

Background: Transcatheter aortic valve replacement (TAVR) is associated with a significant need for permanent pacemaker implantation. Pacing rates vary according to the device used.
Transcatheter aortic valve implantation (TAVI) has become the standard treatment for aortic stenosis in high-risk patients. TAVI for native valve aortic regurgitation is technically more demanding because of a lack of anchoring calcification, a lower index incidence, heterogeneous causes, and larger anatomy. We present 3 cases in which the Lotus TAV was used to treat severe native aortic regurgitation (AR) successfully.

These procedures almost always require bursts of rapid ventricular pacing to temporarily reduce cardiac output to facilitate the procedure, usually done via a temporary pacing wire inserted into the right ventricle. We describe a case series of 132 cases of TAVI and 76 BAV done using ventricular pacing via the left ventricular lead by simply connecting one electrode to the patient's skin and one electrode through the left ventricular (LV) wire.

Report results of valve-in-valve therapy (ViV-TAVI) in failed supra-annular stentless Freedom Solo (FS) bioprostheses, which are the highest risk for coronary occlusion.
Methods: Six patients with FS valves (mean age 78.
Background: Surgical risk scoring systems are of modest value in predicting outcome following transcatheter aortic valve implantation (TAVI). There is no consensus as to which scoring system is the most useful. We examined the efficacy of all four currently available global scorings systems (Additive EuroScore [aES], Logistic EuroScore [LES], EuroScore II [ES II], Society of Thoracic Surgeons [STS] Score) in predicting outcome, both in the short (30 day) and longer term, in patients undergoing TAVI.

View Article and Find Full Text PDFObjective: To assess the success rate and safety outcomes of left atrial appendage occlusion (LAAO) procedures in a cohort of patients who had not undergone preprocedural imaging.
Background: LAAO patients usually undergo imaging with either transesophageal echocardiography (TEE) or computed tomography (CT) prior to the procedure itself. This preprocedural imaging may not be necessary.
Background: Surgical risk scoring systems are poor at predicting outcome in patients undergoing transcatheter aortic valve implantation (TAVI). Frailty indices might more accurately predict outcome.
Aims: To examine multiple frailty indices as markers of performance to see whether they predict outcomes both in the shorter (30 days) and longer terms (5 years) in patients who have undergone TAVI.
Patent foramen ovale has been identified as a conduit for paradoxical embolism resulting in cryptogenic stroke or transient ischemic attack (TIA). We aimed to establish rates of death, recurrent stroke or TIA among patients undergoing PFO closure for stroke or TIA at our unit. A retrospective analysis of all PFO closure patients was performed between May 2004 and January 2013.
