Background. The aim of this study was to compare the effectiveness ampicillin plus ceftriaxone (AC) and gentamicin (AG) combinations for treating Enterococcus faecalis infective endocarditis (EFIE). Methods. An observational, nonrandomized, comparative multicenter cohort conducted at 17 Spanish 1 Italian hospitals. Consecutive adult patients diagnosed EFIE were included. Outcome measurements death during treatment 3 months follow-up, adverse events requiring withdrawal, failure a change...

At least 5-10% of subjects surviving COVID-19 develop the post-COVID-19 condition (PCC) or "Long COVID". The clinical presentation PCC is heterogeneous, its pathogenesis being deciphered, and objective, validated biomarkers are lacking. It unknown if a single entity heterogeneous syndrome with overlapping pathophysiological basis. large US RECOVER study identified four clusters according to their presenting symptoms. However, long-term implications remain unknown.We conducted 2-year...

Evidence regarding any association of HDL-particle (HDL-P) derangements and HDL-cholesterol content with cardiovascular (CV) death in chronic heart failure (HF) is lacking. To investigate the prognostic value HDL-P size (HDL-Sz) number cholesterol molecules per for CV HF patients. Outpatient patients were enrolled. Baseline number, subfractions HDL-Sz measured using 1H-NMR spectroscopy. The HDL-C/P ratio was calculated as over HDL-P. Endpoint death, non-CV competing event. 422 included...

Background: To date, there is little information regarding management of patients with infective endocarditis (IE) that did not undergo an indicated surgery. Therefore, we aimed to evaluate prognosis these treated a long-term antibiotic treatment strategy, including oral long term suppressive in five referral centres multidisciplinary team. Methods: This retrospective, multicenter study retrieved individual patient-level data from Spain. Among total 1797, 32 consecutive IE were examined...

<h3>Objective:</h3> To assess enoxaparin as bridging anticoagulant treatment in cardiac surgery. <h3>Methods:</h3> Prospective registry of those patients who underwent surgery our centre between December 2003 and June 2004 required long-term anticoagulation. Subcutaneous was used according to a pre-established protocol. The global thromboembolic risk carefully assessed all patients. All were followed up for 3 months. <h3>Results:</h3> Of 140 included (mean (SD) age 66 (11); 49% female), 51...

Aims Purpose of this study is to compare the clinical course and outcome patients with recurrent versus first-episode infective endocarditis (IE). Methods Patients IE enrolled in EUROpean ENDOcarditis (EURO-ENDO) registry including 156 centres were identified compared using propensity score matching. Recurrent was classified as relapse when occurred ≤6 months after a previous episode or reinfection &gt;6 prior episode. Results 3106 enrolled: 2839 (91.4%) (mean age 59.4 (±18.1); 68.3% male)...

Left atrial wall haematoma is a very uncommon entity, associated mainly to cardiac surgery, interventional procedures, or trauma. Spontaneous cases are supposed be with left pathology. We present case of 53-year-old male who was admitted for prolonged chest pain, transthoracic and transesophagic echocardiography documentation mass in close proximity mitral annular calcification. Tissue characterization magnetic resonance suggested the aetiology mass, which confirmed histologically.

Ectopic thyroid tissue is a rare congenital anomaly that results from multiple events during development. The ectopic may lie in several human organs including the tongue and mediastinum. It rarely seen as an intracardiac mass. We report case of patient with mass diagnosed by echocardiography. pathology was compatible no signs malignancy.

Background: In asymptomatic severe aortic stenosis (ASAS), treatment decisions are made on an individual basis, and case management presents a clinical conundrum. Methods: We prospectively phenotyped consecutive patients with ASAS using echocardiography, exercise cardiac MRI biomarkers (NT-proBNP, high-sensitivity troponin T (hs-TnT) ST2) (n = 58). The primary endpoint was composite of cardiovascular death, new-onset symptoms, hospitalization, guideline-driven indication for valve...

Background. Transcatheter edge-to-edge repair (TEER) is a safe and effective treatment in symptomatic patients with mitral regurgitation (MR). We aimed to investigate the short-term impact of TEER on left ventricular (LV) performance identify echocardiographic prognostic indicators. Methods. Seventy-eight severe MR (organic functional etiologies) were included retrospectively. All had baseline echocardi-ography after followed up for primary composite endpoint (heart failure hos-pitalization...

Background Pulmonary hypertension ( PH ) is a common cause of right ventricular RV remodeling and functional tricuspid regurgitation FTR ), but incremental pulmonary artery systolic pressure PASP does not always correlate with anatomic changes. This study aimed to evaluate noninvasive measure vascular resistance PVR for predicting dilatation, dysfunction, severity . Methods We prospectively analyzed consecutive stable patients ≥ 35 mm Hg or any degree dilatation dysfunction secondary...
