Right heart strain can often occur as a result of pulmonary arterial hypertension (and its underlying causes such as massive pulmonary emboli). Patients with . See more
The reported sensitivity and specificity of CT in demonstrating right heart dysfunction are around 81% and 47% respectively 5. Described features include: 1. . See moreAccording to the latest European Society of Cardiology (ESC) guideline, a right ventricle–to–left ventricle (LV) diameter ratio >1.0 is the most appropriate method for determining dysfunction . the right ventricular outflow tract is considered enlarged when the measured diameter in the parasternal long axis exceeds 3.3 cm, or when the measured diameter . Consequently, although the normal RV has a lower ratio of volume to surface area and a thinner wall than the LV, 8 the low cavity pressure determines a lower wall stress and .
Evaluation of the right ventricle (RV) is a key component of the clinical assessment of many cardiovascular and pulmonary disorders. There are many ways to evaluate the RV, .

rv Lv ratio pulmonary embolism
The right ventricular to left ventricular diameter (RV:LV) ratio measured at CT pulmonary angiogram (CTPA) has been shown to provide valuable information in patients with .The echocardiographically derived RV/LV endsystolic ratio (RV/LVes ratio) and the LV endsystolic eccentricity index (LVes EI), both measured in the parasternal short axis view, are potentially .The right ventricle (RV) is constructed to accommodate a low-resistance afterload. Increases in afterload from acute massive and submassive PE and CTEPH may markedly compromise the .The primary aim of the study was to evaluate the accuracy of assessing the presence or absence of RV dilatation, defined as an RV/LV diameter ratio of ≥1.0, by three residents in internal .
An increased ratio between the size of the right and left ventricles (RV/LV ratio) is a biomarker of RV dysfunction. This study evaluated the reproducibility of RV/LV ratio . right ventricle/ left ventricle end diastolic basal diameter ratio >1. the right ventricular outflow tract is considered enlarged when the measured diameter in the parasternal long axis exceeds 3.3 cm, or when the measured diameter exceeds 2.7 cm in the distal RVOT, as measured in the basal parasternal short axis view. Right ventricular enlargement (also known as right ventricular dilatation (RVD)) can be the result of a number of conditions, including: pulmonary valve stenosis. pulmonary arterial hypertension. atrial septal defect (ASD) ventricular septal defect (VSD) tricuspid regurgitation. dilated cardiomyopathy. anomalous pulmonary venous drainage.
Right ventricular dysfunction usually results from either pressure overload, volume overload, or a combination. It occurs in a number of clinical scenarios, including: pressure overload. cardiomyopathies: ischemic, congenital. valvular heart disease. arrhythmias. sepsis. It can manifest as right heart strain. Pre-capillary pulmonary hypertension is considered if the pulmonary artery wedge pressure (PAWP) is ≤15 mmHg, pulmonary vascular resistance (PVR) is ≥ 3 Wood units (WU) and mPAP is >20 mmHg. Post-capillary pulmonary hypertension is now defined as mPAP >20 mmHg and PAWP >15 mmHg.

classical definition based on the ratio between non-compacted vs compacted myocardium. increased thickness of the non-compacted layer with a non-compacted/compacted ratio >2.3 consistent with the diagnosis. regional increase in left ventricular trabeculation. predominantly affects the inferolateral walls and the apex. The parasternal long axis and apical four-chamber views on transthoracic echocardiography are often the primary views used to gain both a qualitative and quantitative appreciation of left ventricular enlargement. Features include 4: increased left ventricular internal end-diastolic diameter (LVIDd)
Left ventricular aneurysms are discrete, dyskinetic areas of the left ventricular wall with a broad neck (as opposed to left ventricular pseudoaneurysms), thus often termed true aneurysms. Ventricular dP/dt is the rate of pressure change (dP) with time (dt) during isovolemic contraction of the cardiac ventricles i.e. in the period before the aortic valve and/or pulmonic valve opens, when there is no considerable change in left atrial and or right atrial pressure 1,2.Radiopaedia.org, the peer-reviewed collaborative radiology resource Ventricular dP/dt is the rate of pressure change (dP) with time (dt) during isovolemic contraction of the cardiac ventricles i.e. in the period before the aortic valve and/or pulmonic valve opens, when there is no considerable change in left atrial and or right atrial pressure 1,2.
