“…Meluzin et al (2001), reported that an S' velocity less than 11.5 cm/s was predictive of a RV dysfunction with a sensitivity of 90% and a specificity of 85%. [29] MPI was found to correlate with radionuclide derived RVEF in earlier studies [30].…”

“…In a study done by Fan et al in (2005), S' found to be significantly reduced in patients with proximal RCA lesion and RV-MI as compared to those with non-proximal RCA lesion (7.0 ± 2.0 cm/s vs. 8.7 ± 1.9 cm/s, p < 0.01). RV Tei index in patients with proximal RCA lesion and RV-MI also increased as compared to those with non-proximal RCA lesion (0.65 ± 0.19 vs. 0.40 ± 0.15; p< 0.01) [31].…”

IntroductionRight ventricular (RV) infarction is one of the major causes of RV contractile dysfunction. RV involvement occurs in 20-50% of inferior infarctions [1]. Patients with RV infarction associated with inferior infarction have much higher rates of significant hypotension, bradycardia requiring pacing, and in-hospital mortality compared to isolated inferior infarction [2] Occlusion of proximal dominant RCA is usually responsible for RV infarction in inferior wall myocardial infarction [3] Results: There were 35 patients with first episode of IWMI, group A (n =14 patients) and group B (n =21patients), There were significant differences between groups in TAPSE (1.28cm vs 1.98 p < 0.001), MPI-TDI (0.69±0.12 vs 0.38±0.05 p < 0.001), and in S'velocity from RV free wall ( 0.09m/s±0.02 vs 0.12m/s ±0.02 p < 0.001). It was found that S'<10cm/s is a predictor of proximal RCA lesion with sensitivity of 92.86% and specificity of 85.71%, ppv 81.25, npv 94.74. MPI-TDI>0.55 had a sensitivity of 92.86 % and a specificity of 100%, 100% PPV and 95.45% NPV. TAPSE<16mm had a sensitivity of 93%, and a specificity of 100%. Conclusion: RV indices (S' velocity, MPI-TDI and TAPSE ) are useful in predicting proximal RCA as infarct related artery in IWMI.

“…The ability of MPI to quantitatively assess RV function is validated in adults and patients with congenital heart disease [85,86]. In addition, MPI has demonstrated prognostic power in differentiating outcome in RV failure [87][88][89][90]. Care should be taken in using MPI for congenital heart disease with altered loading conditions.…”

Reliable assessment of ventricular function is an essential for management of patients with heart disease. Noninvasive echocardiographic evaluation is indispensable for repeated assessment of ventricular function in the clinical setting. Alterations of left and right ventricular geometry and loading conditions are the property of congenital heart disease; therefore, quantitative assessment of ventricular function is technically challenging. Systolic ventricular function is pump activity for the generation of an adequate cardiac output with filling pressure as low as possible. A wide variety of different echocardiographic parameters and indices are developed for the assessment of systolic ventricular function; however, no single parameter adequately provides all the necessary information. One should integrate information from different parameters to comprehensively describe systolic function. Echocardiographic assessment of diastolic function is based on Doppler method of mitral inflow and the pulmonary veins with supplemental assessment by tissue Doppler, strain, and strain rate. Although several indices are available, no single indices adequately evaluate diastolic function. Therefore, a comprehensive examination is mandatory as well as in systolic ventricular function. This chapter will discuss traditional and newer echocardiographic techniques for the evaluation of ventricular function and, in addition, vascular function in patients with congenital heart disease.

“…Its comparison with invasive measurements makes the index a sensitive indicator of RV function. This index, also named Tei index, is not influenced by heart rate, body weight, and aging and is correlated with %RVEF obtained by nuclear ventriculography [30]. Tei index can be also obtained using tissue doppler imaging (TDI) [31].…”

The aim of this review was to describe the different ultrasonic modalities to non-invasively evaluate right cardiac chambers and pulmonary vascular bed function. M-Mode, 2-D, conventional pulsed doppler, tissue doppler imaging (TDI), strain rate imaging (SRI) and 3D echocardiography are illustrated in order to obtain both regional and global right heart and pulmonary function. The results have a good correlation with other invasive and non-invasive diagnostic techniques, as magnetic resonance imaging (MRI). All these echocardiograpic techniques can be employed to evaluate the morphologic and functional pictures of right heart and pulmonary circulation in presence of pulmonary hypertension (PH). The hemodynamic profile obtained consent to anatomically and functionally characterize PH. But, other experiences performed on more wide range of healthy and PH patients are necessary to confirm the described results.

Myocardial Performance Index Correlates with Right Ventricular Ejection Fraction Measured by Nuclear Ventriculography

Abstract: MPI greater than 0.50 indicates that RV function is abnormal and a value of PTASV > 17.25 cm/sec indicates normal RV function.
