CLINICAL INVESTIGATIONS • Passive Leg Raise Stress Echocardiography in Severe Paradoxical Low-Flow, Low-Gradient Aortic Stenosis

Management of aortic stenosis (AS) – the most common valvular heart disease in Europe and North America – is done by catheter intervention or surgery; in severe symptomatic AS, valve replacement is the treatment of choice. Diagnosis of severe AS, which is defined as an aortic valve area (AVA) �...

THE HEMODYNAMIC CORNER • Aortic Stenosis Severity: Rhythm Makes a Difference

The assessment of aortic valve stenosis (AS) severity based on Doppler velocity and pressure gradient is ﬂow dependent. Both velocity and pressure gradient increase with elevated transaortic ﬂows and decrease with reduction in ﬂow rates for a given aortic valve oriﬁce area. In this case repo...

REVIEW • Cardiac Imaging for Diagnosis and Management of Infective Endocarditis

In-hospital mortality of infective endocarditis (IE) remains approximately 20%, and 1-year mortality approaches 40%. Decision-making in patients with IE is often complex, requiring collaboration among cardiologists, cardiac surgeons, and infectious disease specialists, among others. Although echocar...

CASE REPORT • A Simple Algorithm for Differential Diagnosis in Hemodynamic Shock Based on Left Ventricle Outflow Tract Velocity–Time Integral Measurement: A Case Series

Pericardial effusions represent a clinical spectrum of disease ranging from asymptomatic to obstructive shock and can be the etiology of nonspeciﬁc cardiopulmonary symptoms, unrecognized shock, and abrupt clinical deterioration. Therefore, identiﬁcation of pericardial effusion remains challengin...

CASE REPORT • A Simple Algorithm for Differential Diagnosis in Hemodynamic Shock Based on Left Ventricle Outflow Tract Velocity–Time Integral Measurement: A Case Series

Echocardiography has been used in the critical care setting for a long time. Several echocardiographic algorithms have been developed with the aim to guide in the assessment of hemodynamic shock in critically ill patients. These algorithms, however, focus mainly on the heart structural and do not of...

STRAIN ECHOCARDIOGRAPHY IN AORTIC STENOSIS • Multichamber Strain Characterization Is a Robust Prognosticator for Both Bicuspid and Tricuspid Aortic Stenosis

Bicuspid aortic valve (BAV) is the most common congenital cardiac abnormality. It is detected in up to 50% of patients requiring aortic valve replacement (AVR) because of signiﬁcant aortic stenosis (AS). Patients with BAV-AS are two decades younger, have fewer comorbidities, and exhibit significan...

CLINICAL INVESTIGATIONS • Left Ventricular Global Longitudinal Strain in Patients with Moderate Aortic Stenosis

Recent data shows poor long-term survival in patients with moderate aortic stenosis, challenging traditional definitions of AS severity and timing of intervention in these patients. The presence of moderate AS in patients with reduced left ventricular ejection fraction (LVEF; ...

CLINICAL INVESTIGATIONS • Comparison of Mitral Regurgitant Volume Assessment between Proximal Flow Convergence and Volumetric Methods in Patients with Significant Primary Mitral Regurgitation: An Echocardiographic and Cardiac Magnetic Resonance Imaging Study

Assessment of primary mitral regurgitation (MR) severity is of paramount importance for clinical decision-making to determine the optimal timing of surgical intervention in these patients. Current guidelines recommend determination of mitral regurgitant volume (RVol) as part of the thorough assessme...

Right Ventricular Postsystolic Strain Curve Morphology before and after Vasodilator Treatment in Idiopathic Pulmonary Arterial Hypertension

The authors discussed the current guidelines for diagnostic workup of pulmonary hypertension, which include right heart catheterization to establish diagnosis, a transthoracic echocardiography to rule out left heart disease, a ventilation/perfusion lung scan to exclude chronic thromboembolic pulmona...

ECHOCARDIOGRAPHY AND PULMONARY HYPERTENSION • Echocardiographic Biventricular Coupling Index to Predict Precapillary Pulmonary Hypertension

Right heart catheterization (RHC) remains the gold standard in the diagnostic workup. However, transthoracic echocardiography is currently part of the screening process and is increasingly used in the longitudinal follow-up of patients with PH. Estimated systolic pulmonary artery pressure (sPAP) is ...
