Relationship between fragmented QRS complex and early left ventricular dysfunction after mitral valve repair.

Background: Preoperative left ventricular (LV) ejection fraction (PreLVEF) and preoperative LV end-systolic diameter (PreESD) are known predictors for postoperative LV dysfunction after mitral valve repair (MVR). Fragmented QRS (fQRS) evaluated in 12-derivation electrocardiography has widely been accepted as a sign of myocardial fibrosis. In the present study, we aimed to evaluate the relationship between fQRS in preoperative 12‑lead electrocardiography (ECG) and postoperative LV dysfunction that develop after MVR in patients with severe primary mitral regurgitation (MR) due to mitral valve prolapse (MVP).

Angio-Seal Used as a Bailout for Incomplete Hemostasis After Dual Perclose ProGlide Deployment in Transcatheter Aortic Valve Implantation.

Background: The failure rate of vascular closure devices remains a significant cause of major vascular complications in contemporary transcatheter aortic valve implantation practice.

Methods: This research aimed to evaluate use of the Angio-Seal device in a bailout context in the setting of incomplete hemostasis following use of dual Perclose ProGlide devices in patients undergoing transfemoral transcatheter aortic valve implantation. A total of 185 patients undergoing transfemoral transcatheter aortic valve implantation with either dual Per-close ProGlide (n = 139) or a combination of dual Perclose ProGlide and Angio-Seal (n = 46) were retrospectively analyzed.

How accurate are manufacturers' recommendations in determining ineligibility for transfemoral transcatheter aortic valve implantation?

Introduction: Up to one-third of patients indicated for transcatheter aortic valve implantation (TAVI) may be unsuitable for transfemoral TAVI (TF-TAVI) according to manufacturers' recommendations and numerous professional societies.

Objective: This study aimed to investigate the predictive value of manufacturers' guidelines for major vascular access site complications using the Perclose ProGlide device.

Methods: Among 208 patients undergoing TF-TAVI, 144 patients (69.

Usefulness of neutrophil-to-lymphocyte ratio for predicting acute pericarditis outcomes.

Background: In daily practice, C-reactive protein (CRP) may be used to predict recurrence and treatment response in patients with acute pericarditis; however, the predictive role of CRP might be insufficient for clinical prediction in some patients. In this study, we aimed to investigate the relationship between neutrophil-to-lymphocyte ratio (NLR) and the composite endpoint of pericarditis recurrence and/or tamponade within 1 year in patients with acute pericarditis.

Methods: A total of 104 patients diagnosed with acute idiopathic pericarditis (mean age 42.

Fragmented QRS on surface electrocardiography as a predictor of cardiac mortality in patients with SARS-CoV-2 infection.

Aims: Although severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection is mainly a respiratory system disease, recent studies reported that cardiac injury is associated with poor outcomes in this population. There are few studies which assessed standard electrocardiogram (ECG) as a prognostic tool during the course of SARS-CoV-2 infection. The aim of this study is to identify the relationship between of ECG parameters and prognosis of patients infected with SARS-CoV-2.

Long-term comparison of everolimus- vs. novolimus-eluting bioresorbable vascular scaffolds in real world patients.

Introduction: Elevated risk of adverse events in comparison to metallic stents resulted in withdrawal of everolimus-eluting bioresorbable scaffolds (eBVS), known as the most intensively studied BVS. There is a paucity of data comparing the two different BVS.

Aim: To evaluate the long-term clinical outcomes of the novolimus-eluting bioresorbable vascular scaffold (nBVS) compared with eBVS.

Outcomes of the novolimus-eluting bioresorbable vascular scaffold in real world clinical practice.

Background: Most of the current data regarding the use of bioresorbable scaffolds (BRS) come from everolimus-eluting stent platforms. Adverse events with the everolimus-eluting BRSs which are the most comprehensively characterized BRS, hampered the clinical use of other BRS. There is paucity of published data regarding long term use of novolimus-eluting BRS.

The relationship between the S-wave in lead 1 and recurrence of RVOT PVC ablation.

Background: Radiofrequency catheter ablation (CA) is a common non-pharmacological treatment option for ventricular premature contractions (PVCs) originating from right ventricular outflow tract (RVOT). In this study, we aimed to investigate the relationship between recurrence after CA for RVOT-PVC and S-wave in lead 1 that was shown to be associated with RVOT depolarization.

Methodology: A total of 104 patients who were referred to our clinic for CA for idiopathic RVOT-PVC between 2012 and 2015years were enrolled.

Is bioresorbable vascular scaffold acute recoil affected by baseline renal function and scaffold selection?

Objective: The aim of the present study was to investigate the relationship between glomerular filtration rate (GFR) and acute post-scaffold recoil (PSR) in patients undergoing bioresorbable scaffold (BVS) implantation.

Methods: We included 130 patients who underwent everolimus-eluting BVS device (Absorb BVS; Abbott Vascular, Santa Clara, CA, USA) or the novolimus-eluting BVS device (Elixir Medical Corporation) implantations for single or multi-vessel disease. Clinical, angiographic variables and procedural characteristics were defined and pre-procedural GFR was calculated for each patient.
