Abstract Background Restrictive cardiomyopathy (RCM) is a common myocardial disease in cats, characterized by diastolic dysfunction and atrial enlargement without myocardial hypertrophy. Especially, endomyocardial form of RCM, one of the subtypes in RCM, is characterized by endocardial fibrosis, endocardial scar bridging the interventricular septum and left ventricular (LV) free wall, and deformation and distortion of the LV. However, it is unclear how the myocardial dysfunction and the endocardial scar contribute to the pathophysiology of RCM disease progression. Case presentation A 3 years and 2 months old, intact male, Domestic shorthaired cat was presented for consultation of cardiac murmur. At the first visit (day 0), the notable abnormal finding was echocardiography-derived chordae tendineae-like structure bridging the interventricular septum and the LV free wall, resulting high-speed blood flow in the left ventricle. Electrocardiography, thoracic radiography and noninvasive blood pressure measurements were normal. No left atrial enlargement was observed, and LV inflow velocity showed an abnormal relaxation pattern. Although there was no abnormality in tissue Doppler imaging-derived myocardial velocity, two-dimensional speckle tracking echocardiography (2D-STE) revealed a decrease in the LV longitudinal strain and an increase in endocardial to epicardial ratio of the LV circumferential strain on day 0. On day 468, obvious left atrium enlargement and smoke like echo in the left atrium were observed. The LV inflow velocity was fused, and the tissue Doppler imaging-derived early-diastolic myocardial velocity of the septal mitral annulus decreased. Regarding 2D-STE, LV circumferential strain was further decreased, and right ventricular strain was additionally decreased. Although the general condition was good, we made a clinical diagnosis of endomyocardial RCM based on the above findings. On day 503, the cat showed the radiographic evidence of pulmonary edema and congestive heart failure signs. Conclusions Cats with abnormal LV structure and associated myocardial dysfunction like this case needs careful observation. Additionally, 2D-STE indices may be useful for early detection of myocardial dysfunction in feline RCM.

The Impact

Despite efforts to treat obstructive sleep apnea syndrome (OSA), the condition remains an important risk factor in the development of cardiovascular disease. Early detection of RV dysfunction with novel echocardiographic techniques (speckle tracking echocardiography) may be useful in preventing progression to pulmonary hypertension, with subsequent heart failure and cardiovascular death. Echocardiography is the method of choice for the evaluation of OSA consequences on the heart. Although standard echocardiographic parameters are routinely used in these patients, there are several limitations in the early detection of RV dysfunction. The main concerns are the complex geometry of RV and the impact of pre- and afterload on RV myocardium, which cannot be assessed through standard measurements. The aim of this review is to highlight the utility of advanced echocardiographic parameters in the identification of OSA patients with subclinical myocardial dysfunction, which are at risk of developing heart failure and later adverse events. Speckle tracking echocardiography might provide higher sensitivity in unmasking alterations in RV function when conventional echocardiographic methods cannot detect them. Therefore, this method has a major role in the detection of early stages of RV dysfunction, along with better risk stratification and better timing in the initiation of therapy.

The aim: To improve efficacy of the right ventricle functional condition evaluation in children with tetralogy of Fallot after surgical correction by estimation of instrumental markers of myocardial dysfunction. Materials and methods: We completely examined 35 children with tetralogy of Fallot after their surgical correction at the age of 3 – 17 years. For all the patients was presented tissue doppler. We evaluated peak myocardial velocities of right ventrical in different phases of the heart cycle (S, E`, A`), tricuspid annular plane systolic excursion (TAPSE), diastolic myocardial velocities ratio (E/E`), peak myocardial velocity during isovolumic contraction (IVV), isovolumic relaxation time (IVRT). Results: All children of the study group had pulmonary insufficiency of different severity with main predominance of mild pulmonary regurgitation (20 patients, 57,14±8,36 %). Children with tetralogy of Fallot after surgical correction were admitted with: decreased TAPSE up to 1,39±0,28 cm, decreased S` up to 8,00±1,90 cm/s, and decreased IVV up to 5,69±0,95 cm/s that is significantly lower results of the healthy children. Severe pulmonary regurgitation usually followed by high chances of the right ventricle systolic dysfunction, exactly with: decresed TAPSE<1,5 cm (OR=0,500; 95% CI 0,323 – 0,775), S`<8,1 cm/s (OR=0,600; 95% CI 0,420 – 0,858) and IVV<5,9 cm/s (OR=0,250; 95% CI 0,117 – 0,534). As well we admitted significant decline of the velocities in earl and end diastole periods to compare with the results of the control group (E`= 12,11±1,22, A`= 4,56±0,92 cm/s (Р=0,009 and P=0.0002)), boost of the E/E` ratio – 7,96±2,33 (P=0.01) and decline of the RV IVRT up to 43,49±6,04 ms (P=0.017). Severe pulmonary regurgitation followed by high chances of the right ventricle systolic dysfunction development with TAPSE <1,5 cm (OR=0,500; 95% CI 0,323 – 0,775), S`<8,1 cm/s (OR=0,600; 95% CI 0,420 – 0,858) and IVV<5,9 cm/s (OR=0,250; 95% CI 0,117 – 0,534). As well we noticed high chances of the E/E`ratio > 6,0 in 1,5 times (95% CI 1,072 – 1,903) and decreased E` <12,2 cm/s (OR=0,200; 95% CI 0,083 – 0,481). Conclusions: Apart of clinical symptoms of the heart failure in children with tetralogy of Fallot after surgical correction markers of the right ventricle myocardial dysfunction are presented by indices of myocardial velocities, received during tissue doppler in different phases of the heart cycle.
