Superior vena cava (SVC) isolation during atrial fibrillation catheter ablation is limited by the risk of collateral damage to sinus node and/or phrenic nerve. Due its tissue-specificity, we hypothesized feasibility and safety pulsed-field (PFA)-based SVC isolation.
Color Doppler imaging is an established pulsed ultrasound technique to visualize blood flow non-invasively. High-frame-rate (ultrafast) color Doppler, by emissions of plane or circular wavefronts, allows severalfold increase in frame rates. Conventional and ultrafast are both limited the range-velocity dilemma, which may result velocity folding (aliasing) for large depths and/or velocities. We investigated multiple pulse-repetition-frequency (PRF) arranged a series staggered intervals remove...
We sought to describe our experience with major coronary anomalies (MCAs) diagnosed in transthoracic echocardiography (TTE) a large adult and paediatric population. MCAs may have serious clinical consequences. No echocardiographic studies prospectively screened MCA general population.From June 2008 January 2012, systematic search for was conducted children patients, coming TTE. Three thousand five hundred two patients (84% adults 16% children) underwent Fourteen (0.39%) were diagnosed: nine...
Echocardiographic ratio of peak tricuspid regurgitant velocity to the right ventricular outflow tract time-velocity integral (TRV/TVI rvot) was presented as a reliable non-invasive method estimating pulmonary vascular resistance (PVR). Studies using this technique in patients with moderate high PVR are scarce. Left (TVI lvot) can be easier measure than TVI rvot, especially severe hypertension (PH) significant anatomical modifications structures. We wanted determine whether TRV/TVI rvot and...
Obesity may have implications in the myocardial structural change, which contribute to mechanical consequences. Using 2D speckle echocardiography, we looked for changes and investigated their relation obesity, inflammation, insulin resistance physical capacity children with isolated obesity. Standard echocardiography strain were prospectively performed obese compared them age- sex-matched controls. Z-score body mass index (BMI Z-score), ultra-sensitive C reactive protein, indices of...
Myocardial inflammation has been consistently associated with genetic arrhythmogenic cardiomyopathy (ACM) and it hypothesized that episodes mimicking acute myocarditis (AM) could represent early inflammatory phases of the disease.We evaluated temporal association between recurrent (RAM) later diagnosis a ACM.Between January 2012 December 2021, patients RAM no previous were included (Recurrent Acute Myocarditis Registry, NCT04589156). A follow-up visit including clinical evaluation, resting...
After an old myocardial infarction (MI), patients are at risk for reentrant ventricular tachycardia (VT) due to scar tissue that can be accurately identified by late gadolinium enhancement cardiac magnetic resonance (LGE-CMR). Although the ability of LGE-CMR predict sustained VT in implantable cardioverter-defibrillator (ICD) recipients has been well established, its use monomorphic (sustained or not) cycle length (CL) and so, optimize ICD programming never investigated. We included...
Abstract Aims Limited data exist concerning fragmented QRS complexes (fQRSs) on the surface electrocardiogram (ECG) of apparently healthy athletes. We aimed to study prevalence and significance fQRS in lead V1 (fQRSV1), representing right ventricular (RV) activation, regarding training-induced RV morphological remodelling. Methods results Between January 2017 August 2019, 434 consecutive non-sedentary subjects underwent preparticipation cardiovascular screening, including a 12-lead ECG....
The left ventricular ejection fraction (LVEF) is the key selection criterion for an implanted cardioverter defibrillator (ICD) in primary prevention of sudden cardiac death. LVEF usually assessed by two-dimensional echocardiography, but cardiovascular magnetic resonance (CMR) imaging increasingly used. aim our study was to evaluate whether assessment using CMR (CMR-LVEF) or echocardiography (2D echo-LVEF) may predict differently occurrence clinical outcomes.
Infective endocarditis caused by a zoonotic micro-organism is rare clinical condition. Capnocytophaga canimorsus bacterium of the normal oral flora dogs and cats. It can be transmitted to humans bite, scratch or others close contacts with dogs, occasionally has been implicated in spectrum disorders including septicemia, meningitis septic arthritis. Splenectomy alcoholism have reported risk factors, but infection may occur previously healthy patients. We case 65-year-old man bicuspid...
Pre-participation screening and management of congenital cardiac valvulopathy in competitive athletes can be challenging, particularly within the context ultra-endurance disciplines. A 55-year-old female athlete without a reported history disease exhibited clinical signs cardiogenic pulmonary edema during 156 km ultra-trail race. The echocardiographic assessment revealed presence parachute mitral valve, with no evidence stenosis or regurgitation at rest, but it demonstrated severe dynamic...
Abstract Background Cardiac resynchronization therapy has been shown to benefit selected patients with heart failure and reduced ejection fraction. Older have underrepresented in randomized trials. This study was conducted determine whether predictive factors for cardiac outcomes differ older younger than 75 years of age. Methods Consecutive who received a device between 2013 2016 our center were retrospectively included this cohort study. The primary endpoint effectiveness, which defined as...
