Differential features of Infective endocarditis caused by oral streptococci in the Reina Sofia University Hospital, Córdoba (Spain): 1987-2023 period.

Introduction And Objectives: Infective endocarditis (IE) caused by oral streptococci is considered to be a 'more benign' IE than those caused by other microorganisms. Our aim is to analyse the changes in its incidence and its differential characteristics in our setting.

Methods: Observational, single-centre, prospective cohort study including all cases of IE diagnosed in our centre between 1987 and 2023.

New severity criteria for tricuspid regurgitation in a broad population of "real life" patients: Prevalence and prognostic impact.

Introduction Our objective was to determine, in "real life" patients, the prevalence of massive and torrential regurgitation among patients diagnosed with severe tricuspid regurgitation (TR), as well as its impact on long-term prognosis. Methods In a single-center retrospective study, all patients with an echocardiographic diagnosis of severe TR attended at a tertiary care hospital of an European country from January 2008 to December 2017 were recruited. Images were analysed off-line to measure the maximum vena contracta (VC) and TR was classified into three groups: severe (VC ≥ 7 mm), massive (VC 14-20 mm), and torrential (VC ≥ 21 mm).

A novel approach for venous occlusion after endocavitary leads. The balloon-assisted tracking technique.

The balloon-assisted tracking technique can be useful in short venous occlusions that conventional venoplasty fails. This technique could be feasible and with an expected low complication rate.

The effects of obesity on longitudinal ventricular and atrial strain in a rural population of Spanish children and adolescents, evaluated by a new strain software.

Background And Objectives: Research on the relationship between body mass index (BMI) and strain values in children and adolescents is limited. Our aim was to analyse the relationship between BMI and strain values of both ventricles and left atrium in children and adolescents.

Methods: Both ventricles and left atrial strain values were compared among different BMI categories in children and adolescents from a town in the South of Spain.

The Role of Left Atrial Longitudinal Strain in the Diagnosis of Acute Cellular Rejection in Heart Transplant Recipients.

Our aim was to investigate the role of left atrial longitudinal strain (LALS) in the non-invasive diagnosis of acute cellular rejection (ACR) episodes in heart transplant (HTx) recipients. Methods: We performed successive echocardiographic exams in 18 consecutive adult HTx recipients in their first year after HTx within 3 h of the routine surveillance endomyocardial biopsies (EMB) in a single center. LALS parameters were analyzed with two different software.

Relationship between overweight and obesity and cardiac dimensions and function in a paediatric population.

Unlabelled: Obesity in adults is associated with left ventricular hypertrophy, dilatation, and myocardial fibrosis, as well as heart failure and coronary heart disease. These associations have been studied to a lesser extent in the paediatric population. This study aims to investigate the relationship between obesity and cardiac structure and function in the paediatric population.

Impact on daily clinical practice of the latest evidence on percutaneous closure of patent foramen ovale after cryptogenic stroke: a single-center experience.

Introduction And Objectives: At the end of 2017, three clinical trials demonstrated that, in selected patients, percutaneous closure of patent foramen ovale (PFO) after cryptogenic stroke (CS) reduces the risk of recurrence. Our aim was to determine the impact of these findings on routine clinical practice in a tertiary hospital.

Methods: Patients with CS and percutaneous closure of PFO during 2001-2020 were included.

Spanish registry of percutaneous VSD closure with NitOcclud Lê VSD Coil device: lessons learned after more than a hundred implants.

Introduction And Objectives: The NitOcclud Lê VSD Coil was specifically designed for transcatheter occlusion of ventricular septal defects (VSD) and became available for this purpose in August 2010. Our objective was to describe the Spanish experience of this technique and analyze its reliability and short- to mid-term efficacy.

Methods: National multicenter observational study, which retrospectively recruited all patients (of any age) with VSD (of any location or type) who underwent percutaneous NitOcclud occlusion, using an intention-to-treat analysis, until January 2019.

Prosthesis-patient mismatch after transcatheter aortic valve replacement: prevalence and medium term prognostic impact.

Prosthesis-patient mismatch (PPM) occurs when the effective orifice area of the prosthesis is too small in relation to the patient's body surface area. There are few data available on the frequency and prognostic impact of PPM after transcatheter aortic valve implantation (TAVI). Our aim was to determine the prevalence of PPM and to investigate its association with medium-term clinical course of patients undergoing TAVI.

Long-term Survival in a Spanish Population With Stable Ischemic Heart Disease. The CICCOR Registry.

Introduction And Objectives: Data are lacking on the long-term prognosis of stable ischemic heart disease (SIHD). Our aim was to analyze long-term survival in patients with SIHD and to identify predictors of mortality.

Methods: A total of 1268 outpatients with SIHD were recruited in this single-center prospective cohort study from January 2000 to February 2004.

Spanish Cardiac Catheterization and Coronary Intervention Registry. 26th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology (1990-2016).

Introduction And Objectives: The Working Group on Cardiac Catheterization and Interventional Cardiology presents its annual report on the activity data for 2016.

Methods: All Spanish hospitals with catheterization laboratories were invited to voluntarily contribute their activity data. The information was collected online and was analyzed mainly by an independent company.

One Versus 2-stent Strategy for the Treatment of Bifurcation Lesions in the Context of a Coronary Chronic Total Occlusion. A Multicenter Registry.

Introduction And Objectives: There is little evidence on the optimal strategy for bifurcation lesions in the context of a coronary chronic total occlusion (CTO). This study compared the procedural and mid-term outcomes of patients with bifurcation lesions in CTO treated with provisional stenting vs 2-stent techniques in a multicenter registry.

Methods: Between January 2012 and June 2016, 922 CTO were recanalized at the 4 participating centers.

Effect of New-Onset Left Bundle Branch Block After Transcatheter Aortic Valve Implantation (CoreValve) on Mortality, Frequency of Re-Hospitalization, and Need for Pacemaker.

New-onset conduction disturbances are common after transcatheter aortic valve implantation (TAVI). The most common complication is left bundle branch block (LBBB). The clinical impact of new-onset LBBB after TAVI remains controversial.

Atrioventricular Conduction Changes After CoreValve Transcatheter Aortic Valve Implantation.

Introduction And Objectives: Conduction disturbances often occur after CoreValve transcatheter aortic valve implantation. The aim was to analyze which cardiac conduction changes occur in patients with aortic stenosis treated with this type of prosthesis.

Methods: A total of 181 patients with severe aortic stenosis treated with this prosthesis and studied by electrocardiography between April 2008 and December 2013 were selected.

Mitral regurgitation during transcatheter aortic valve implantation: the same complication with a different mechanism.

Aims: Mitral regurgitation (MR) is a complication that may occur during transcatheter aortic valve implantation (TAVI) in a certain percentage of cases and may require different treatments depending on the mechanism. Our purpose was to describe the occurrence rate of this complication during TAVI with the CoreValve prosthesis, as well as to assess the usefulness of transesophageal echocardiogram (TEE) in the detection of the mechanism of MR.

Methods And Results: We analyzed a total of 129 cases of severe aortic stenosis treated with CoreValve prosthesis from June 2008 to October 2011.

Optical coherence tomography evaluation of late strut coverage patterns between first-generation drug-eluting stents and everolimus-eluting stent.

Objectives: To compare strut coverage patterns between everolimus-eluting stent (EES) and first-generation drug-eluting stents (DES) at more than 12 months after successful implantation, using optical coherence tomography (OCT).

Background: No sufficient OCT data has been reported comparing late strut coverage patterns between EES and first-generation DES. The favorable late results after EES implantation could be related to lower rates of uncovered and malapposed struts.

Monitoring complex secundum atrial septal defects percutaneous closure with real time three-dimensional echocardiography.

Background: Atrial septal defect (ASD) is one of the most common congenital heart diseases. Nowadays, percutaneous closure is considered the treatment of choice in most of secundum ASDs. Assessment of the defect and procedure monitoring have been usually performed by angiographic balloon-sizing and/or two-dimensional (2D) transesophageal echocardiography.
