Background: The prognostic importance of right ventricular (RV) dysfunction has been suggested in patients with systolic heart failure (due to primary or secondary dilated cardiomyopathy - DCM). Tricuspid annular plane systolic excursion (TAPSE) is a simple, feasible, reality, non-invasive measurement by transthoracic echocardiography for evaluating RV systolic function. Objectives: To evaluate TAPSE in patients with primary or secondary DCM who have left ventricular ejection fraction ≤ 40% and to find the relation between TAPSE and LVEF, LVDd, RVDd, RVDd/LVDd, RA size, severity of TR and PAPs. Materials and Methods: 61 patients (36 males, 59%) mean age 58.6 ± 14.4 years old with clinical signs and symtomps of chronic heart failure which caused by primary or secondary DCM and LVEF ≤ 40% and 30 healthy subject (15 males, 50%) mean age 57.1 ± 16.8 were included in this study. All patients and controls were underwent echocardiographic examination by M-mode, two dimentional, convensional Dopler and TAPSE. Results: TAPSE is significant low in patients compare with the controls (13.93±2.78 mm vs 23.57± 1.60mm, p<0.001). TAPSE is linearly positive correlate with echocardiographic left ventricular ejection fraction (r= 0,43; p<0,001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation was found with LVDd and PAPs. Conclusions: 1. Decreased RV systolic function as estimated by TAPSE in patients with systolic heart failure primary and secondary DCM) compare with controls. 2. TAPSE is linearly positive correlate with LVEF (r= 0.43; p<0.001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation is found with LVDd and PAPs. 3. TAPSE should be used routinely as a simple, feasible, reality method of estimating RV function in the patients systolic heart failure DCM (primary and secondary).

Abstract Background The right atrium (RA) is a highly dynamic chamber with 3 mechanical functions (reservoir, conduit, booster pump) and prognostic implications in heart failure (HF) and pulmonary hypertension (PH). However, RA function and its interplay with the right ventricular (RV) performance in patients (pts) with reduced left ventricular ejection fraction (LVEF) and without PH remain to be clarified. Methods We used three-dimensional echocardiography to study 55 pts (61 ± 14 years, 43 men) with LVEF &lt; 40% no more than mild tricuspid regurgitation (TR), and maximum velocity of the TR jet &lt; 3 m/s. We measured the three-dimensional RA total, passive, active ejection volumes (EV) and the respective emptying fractions (EF). In addition, we compared RV volumes and ejection fraction (RVEF) between patients with normal and abnormal RA function. Results Mean LVEF was 30 ± 7%. Mean echo-derived pulmonary vascular resistance was 1.64 ± 0.54 Wood units. 28 pts (51%) had reduced RA reservoir function (total EF = 34 ± 9%), 34 pts (62%) had reduced RA conduit function (passive EF = 15 ± 4%), and 10 pts (18%) had reduced RA pump function (active EF = 11 ± 3%). Pts with reduced RA reservoir function showed larger RV end-systolic volume (RVESV 124 ± 48ml vs. 90 ± 32ml; p = 0.004) and lower RVEF (38 ± 8% vs. 46 ± 6%; p &lt; 0.001) than pts with normal RA function. Pts with reduced RA conduit function showed smaller RV stroke volume (RVSV 65 ± 19 ml vs. 80 ± 22ml; p = 0.009). Pts with impaired RA pump function showed larger RVESV (142 ± 45ml vs. 99 ± 41ml; p = 0.02) and lower RVEF (36 ± 6% vs. 43 ± 8%; p = 0.006). RVESV was positively correlated with total (r2 = 0.47, p &lt; 0.001), passive (r2 = 0.29, p = 0.03) and active (r2 = 0.39, p = 0.003) RAEV, while it was negatively correlated with total (r2=-0.41, p = 0.002), passive (r2=-0.34, p = 0.01) and active (r2=-0.31, p = 0.02) RAEF. RVSV showed a positive correlation with both total (r2 = 0.4, p = 0.002) and passive (r2 = 0.41, p = 0.002) RAEV. Finally, RVEF was positively correlated with total (r2 = 0.51, p &lt; 0.001), passive (r2 = 0.47, p &lt; 0.001), and active (r2 = 0.36, p = 0.007) RAEF. Conclusions RA dysfunction is not uncommon in pts with reduced LVEF, even in the absence of PH. In these pts, RA function is associated with significant changes in RV function. The RA acts as a dynamic modulator of RV pump function by redistributing RV filling and ejection force among reservoir, conduit and pump functions in the setting of altered hemodynamics. The clinical and prognostic significance of RA function in pts with reduced LVEF warrant further studies.

Ventricular thrombus is an uncommon, severe condition with high morbidity and mortality. Simultaneous left and right ventricular thrombi caused by lupus myocardiopathy have not been previously reported in the literature. This case presents a 42-year-old woman who has bilateral ventricular thrombi with reduced left ventricular ejection fraction (35.4%) and acute kidney injury. Pro-brain natriuretic peptide was >35000 pg/mL. Systemic lupus erythematosus was confirmed based on multiorgan injuries including malar rash, anemia, renal injury, positive antinuclear, anti-Smith antibodies, and decreased complements. Renal biopsy revealed lupus nephritis class III + V. Low molecular weight heparin, steroids, and mycophenolate mofetil were initiated, after which the patient experienced transient numbness in the right limbs and hemoptysis. She then recovered quickly and improved significantly with recovery of left ventricular systolic function (left ventricular ejection fraction 46%) and the eventual disappearance of thrombi. Simultaneous left and right ventricular thrombi are rare but life-threatening condition, prompting consideration of myocardiopathy caused by autoimmune diseases such as lupus. Timely treatment with immunosuppressants and anticoagulants may resolve the thrombi and improve cardiac function.
