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).

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.
