“…166 Estes achados têm implicações prognósticas relativamente importantes para os pacientes com embolia pulmonar, 167 e são totalmente reversíveis à medida que ocorre melhora do padrão hemodinâmico pulmonar.36 Em pacientes com doença vascular pulmonar de longa data ou outras formas de hipertensão pulmonar secundária (incluindo DPOC, enfisema e outras formas de doença parenquimatosa) o VD tende a se hipertrofiar e normalizar os volumes inicialmente, seguido eventualmente de dilatação progressiva. 168 O tamanho do VD pode ser influenciado ainda por doenças intrínsecas ao VE. Pacientes com disfunção secundária a infarto do miocárdio ou insuficiência cardíaca apresentam maior risco de dilatação e disfunção do VD.…”

“…Thus, the usefulness of this technique lies not only in predicting the presence or absence of pulmonary hyper tension, but it should also become valuable in detecting its progression. Because it is now recognized that many divergent conditions frequently predispose to elevated pulmonary pressures and associated right ventricular dysfunction [20], an accurate noninvasive technique (such as ours), which allows initial evaluation followed by serial noninvasive re-evaluations, should become a valuable new clinical tool. Doppler flow dynamics, particularly pertaining to the laminar or nonturbulent flow, are perhaps more reflec tive of the vascular impedance, hence a better correla tion with PVR rather than MPAP.…”

We examined a pulsed Doppler index between the acceleration time and right ventricular ejection time (derived from the pulmonic flow velocity pattern) for noninvasive evaluation of pulmonary hypertension. Ninetyeight patients were analyzed prospectively prior to cardiac catheterization; invasive pressure data were then compared to this Doppler index. Using a mean pulmonary arterial pressure >20 mm Hg, and pulmonary vascular resistance > 120 dyn•s•cm^–5 to define the presence of pulmonary hypertension, it was found that the best noninvasive correlation with the extent of pulmonary hypertension occurs when the Doppler index is compared to the logio of pulmonary vascular resistance. An index of <0.29 correctly identified all patients with increased pulmonary vascular resistance, and an index of >0.39 always correctly predicted subjects having normal pulmonary vascular resistance. This Doppler index is, therefore, quite useful to accurately and noninvasively monitor pulmonary arterial pressures in patients who need frequent sequential evaluations.

“…Assessment of right ventricular (RV) performance is of interest, not only in conditions affecting the RV, but also for evaluation of interaction of both ventricles in left ven tricular (LV) disease, such as dilated cardiomyopathies [1][2][3]. Thermodilution techniques are readily available at bedside, repeatable and require minimum equipment and interpretative skill while exposing the patient to minimal risk [4], Recently, the development of fast response ther mistors stimulated the interest in evaluation of RV vol umes and ejection fraction (EF) by this method.…”

Comparative Assessment of Right Ventricular Volumes and Ejection Fraction by Thermodilution and Magnetic Resonance Imaging in Dilated Cardiomyopathy

et al. 1995

Measurements of right ventricular (RV) ejection fraction (EF) and volumes using a new thermodilution technique were compared to serially performed magnetic resonance imaging (MRI) in 21 patients with dilated cardiomyopathy. For RVEF (%) and RV volume indices (ml/m²) the following correlation coefficients were found: RVEF r = 0.82; end-diastolic volume index (EDVI) r = 0.45; end-systolic volume index (ESVI) r = 0.65; stroke volume index (SVI) r= 0.61; all p < 0.05. However, RVEF by thermodilution was significantly lower (RVEF thermo = 31 ± 14 vs. RVEF MRI = 50 ± 14, p < 0.01) and RV EDV and ESVI were significantly higher compared to MRI, while SVI showed no significant difference. Exclusion of patients with atrial fibrillation (n = 8) improved the correlations (RVEF r = 0.94, EDVI r = 0.77, ESVI r = 0.87, SVI r = 0.65, all p < 0.05), but did not reduce the mean difference between both methods.
