    • Coronavirus disease-2019 (COVID-19) outbreak has become a worldwide healthcare emergency, with continuously growing number of infected subjects. Considering the easy virus spread through respiratory droplets produced with cough, sneezes or spit or through close contact with infected people or surfaces, healthcare workers are further exposed to COVID-19. Particularly, echocardiography remains an essential diagnostic service which, due to the close contact with patients during the exam, provides echocardiographers high-risk of contagion. Therefore, the common modalities of performing echocardiography should be improved in this scenario, avoiding performing unnecessary exams, using the appropriate personal protective equipment depending on patients' status and location, optimizing time-effectiveness of the echocardiographic study and accurately sanitizing the environment and devices after each exam. This paper aims to provide a simple guide for the clinicians to balance between providing the best care to each patient and protecting themselves and other patients from the spread of the virus. It also proposes the use of the mnemonic PREVENT to resume the crucial indications to be followed for the execution of appropriate echocardiographic examination during the COVID-19 pandemic.

  • Detection of myocardial fibrosis by speckle-tracking echocardiography : from prediction to clinical applications
  • 2022

    • Myocardial fibrosis (MF) represents the underlying pathologic condition of many cardiac disease, leading to cardiac dysfunction and heart failure (HF). Biopsy studies have shown the presence of MF in patients with decompensating HF despite apparently normal cardiac function. In fact, basic indices of left ventricular (LV) function, such as LV ejection fraction (EF), fail to recognize subtle LV dysfunction caused by MF. Cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) is currently recognized as the gold standard imaging investigation for the detection of focal and diffuse cardiac chambers MF; however, its use is limited by its availability and the use of contrast agents, while echocardiography remains the first level cardiac imaging technique due to its low cost, portability and high accessibility. Advanced echocardiographic techniques, above all speckle-tracking echocardiography (STE), have demonstrated reliability for early detection of structural myocardial abnormalities and for the prediction of prognosis in acute and chronic HF. Myocardial strain of both ventricles and also left atrium has been shown to correlate with the degree of MF, providing useful prognostic information in several diseases, such as HF, cardiomyopathies and valvular heart disease. This paper aims to provide an overview of the pathophysiology of MF and the clinical application of STE for the prediction of left and right heart chambers MF in HF patients.

  • Left atrial myocardial intrinsic function remodeling response to repair of primary mitral regurgitation
  • 2022
  • Ingår i: Echocardiography. - : John Wiley & Sons. - 0742-2822 .- 1540-8175. ; 39:10, s. 1264-1268

    • Severe mitral regurgitation (MR) is a common valve disease which is associated with high mortality, if only managed medically. MR produces chronic and progressive volume overload with left atrial (LA) and left ventricular (LV) dilatation and dysfunction, atrial fibrillation (AF) and eventually myocardial fibrosis, irrespective of ejection fraction (EF). Surgical correction (mitral valve repair) of MR removes the volume overload, hence unmasks pre-operative LV structure and function disturbances, including reduced EF and global longitudinal and circumferential strain, as well as LA volume and strain. This review aims at describing LA remodeling before and after surgical repair.

  • Left atrial remodeling in response to aortic valve replacement : pathophysiology and myocardial strain analysis
  • 2022
  • Ingår i: Life. - : MDPI. - 2075-1729. ; 12:12
  • Forskningsöversikt (refereegranskat)abstract
    • Severe aortic stenosis (AS) is the most common valve disease in the elderly and is associated with poor prognosis if treated only medically. AS causes chronic pressure overload, concentric left ventricular (LV) hypertrophy, myocardial stiffness, and diastolic dysfunction. This adverse remodeling also affects the left atrium (LA), which dilates and develops myocardial fibrosis, with a reduction in intrinsic function and a consequent high risk of the development of atrial fibrillation. Speckle-tracking echocardiography is able to detect myocardial dysfunction before other conventional parameters, such as LV ejection fraction, and also predict clinical outcomes. This review aims at describing LV and LA remodeling in AS and before and after aortic valve replacement and the usefulness of myocardial strain analysis in this clinical setting.

    • Aims: In patients with heart failure (HF), chronically raised left ventricular (LV) filling pressures lead to progressive left atrial (LA) dysfunction and fibrosis. We aimed to assess the correlation of LA reservoir strain (peak atrial longitudinal strain, PALS) by speckle tracking echocardiography (STE) and LA fibrosis assessed by myocardial biopsy in patients undergoing heart transplantation (HTx).Methods and results: Forty-eight patients with advanced HF [mean age 51.2 ± 8.1 years, 29% females; LV ejection fraction ≤25% and New York Heart Association (NYHA) class III–IV] referred for HTx were enrolled and underwent pre-operative echocardiographic evaluation, right heart catheterization, and cardiopulmonary exercise testing. Exclusion criteria were non-sinus rhythm, mechanical ventilation, severe mitral/tricuspid regurgitation, or other valvular disease and poor acoustic window. After HTx, LA bioptic samples were collected and analysed to determine the extent of myocardial fibrosis (%). LA fibrosis showed correlation with PALS (R = −0.88, P < 0.0001), VO2max (R = −0.68, P < 0.0001), NYHA class (R = 0.66, P < 0.0001), LA stiffness (R = 0.58, P = 0.0002), and E/e' (R = 0.44, P = 0.005), while poorly correlated with E/A ratio (R = 0.23, P = 0.21). PALS had a good correlation with NYHA class (R = −0.64, P < 0.0001), PAoP (R = −0.61, P = 0.03) and VO2max (R = 0.57, P = 0.0001). Multivariate regression analysis identified PALS (beta = −0.91, P < 0.001) and LA Volume (beta = −0.19, P = 0.03) as predictors of LA Fibrosis, while E/e’ was not a significant predictor (beta = 0.15, P = 0.08).Conclusion: Emerging as a possible index of myocardial fibrosis in patients with advanced HF, PALS could help to optimize the management and the selection of those patients with irreversible LA structural damage for advanced therapeutic strategies.

  • Novel approaches in cardiac imaging for non-invasive assessment of left heart myocardial fibrosis
  • 2021
  • Ingår i: Frontiers in Cardiovascular Medicine. - : Frontiers Media SA. - 2297-055X. ; 8
  • Forskningsöversikt (refereegranskat)abstract
    • In the past, the identification of myocardial fibrosis was only possible through invasive histologic assessment. Although endomyocardial biopsy remains the gold standard, recent advances in cardiac imaging techniques have enabled non-invasive tissue characterization of the myocardium, which has also provided valuable insights into specific disease processes. The diagnostic accuracy, incremental yield and prognostic value of speckle tracking echocardiography, late gadolinium enhancement and parametric mapping modules by cardiac magnetic resonance and cardiac computed tomography have been validated against tissue samples and tested in broad patient populations, overall providing relevant clinical information to the cardiologist. This review describes the patterns of left ventricular and left atrial fibrosis, and their characterization by advanced echocardiography, cardiac magnetic resonance and cardiac computed tomography, allowing for clinical applications in sudden cardiac death and management of atrial fibrillation.
