Abstract Aims Venous thromboembolism represents frequent complication of patients with severe COVID-19 disease. Several reports about atypical thrombosis are described, rarely it has been described a right venticular thrombus during the course of infection. We report a case of right endoventricular thrombosis in a patient with SARS-Cov-2 pneumonia. Methods and results A 58-year-old man was admitted to our ward for severe respiratory failure in interstitial pneumonia. The nasopharyngeal swab for COVID-19 resulted positive. Steroids and prophylaxis with LMWH were started, associated to CPAP to maintain good gas exchange. During hospitalization a venous ECD was performed with evidence of left popliteal thrombosis despite the therapy. d-Dimer was 4463  ng/ml. A new onset AF was documented at the telemetry, without troponin elevation. A cardiac ultrasound was performed showing a right endoventricular lesion of 1.8  cm adhering to the free wall of the right ventricle. A CT-pulmonary angiogram (CTPA) resulted negative for pulmonary embolism and confirmed suspected right ventricular thrombus. Treatment with fondaparinux 7.5 mg was started. After 10 days, cardiac ultrasound shown complete resolution of thrombosis, and CT confirmed the disappearing of the mass. Dabigatran 150  mg twice/day was started. Patient clinically improved and he was discharged after 20 days of hospitalization. Conclusions SARS-CoV-2 infection may cause inflammation with cytokine storm and hypercoagulability leading to venous thromboembolism. Atypical thrombus formation was reported, including right-ventricle free wall. Early caridac ultrasound was critical to make diagnosis and starting prompt treatment, therefore routine cardiac ultrasound is mandatory in severe COVID-19 patients.

A 46-year-old woman presented with sudden onset of shortness of breath and pleuritic chest pain. A CT pulmonary angiogram identified a 5 cm cement pulmonary embolus within the right main pulmonary artery with a surrounding thrombus. She had undergone an L4 vertebroplasty 3 years prior to presentation for a benign lytic lesion. Cement embolus is a known complication of cement vertebroplasty with incidence rates of approximately 0.9%. Management is usually conservative and associated morbidity and mortality rates are low. It is not known whether a previous cement embolus could provide a nidus for thrombus formation.

Abstract Introduction Precapillary pulmonary hypertension (pPH) causes right ventricular (RV) pressure overload inducing RV remodeling, often resulting in dysfunction and dilatation, heart failure, and ultimately death. The ability of the right ventricle to adequately adapt to increased pressure loading is key for patients' prognosis. RV ejection fraction (RVEF) by cardiac magnetic resonance (CMR) is related to outcome in pPH patients, but this global measurement is not ideal for detecting early changes in RV function. Strain analysis on CMR using feature tracking (FT) software provides a more detailed assessment, and might therefore detect early changes in RV function. Aim 1) To compare RV strain parameters in pPH patients and healthy controls, and 2) to compare strain parameters in a subgroup of pPH patients with preserved RVEF (pRVEF) and healthy controls. Methods In this prospective study, a CMR was performed in pPH patients and healthy controls. Using FT-software on standard cine images, the following RV strain parameters were analyzed: global, septal, and free wall longitudinal strain (GLS, sept-LS, free wall-LS), time to peak strain (TTP, as a % of the whole cardiac cycle), the fractional area change (FAC), global circumferential strain (GCS), global longitudinal and global circumferential strain rate (GLSR and GCSR, respectively). A pRVEF is defined as a RVEF >50%. To compare RV strain parameters in pPH patients to healthy controls, the Mann-Whitney U test was used. Results 33 pPH-patients (55 [45–63] yrs; 10 (30%) male) and 22 healthy controls (40 [36–48] yrs; 15 (68%) male) were included. All RV strain parameters were significantly reduced in pPH patients compared to healthy controls (see table), except for GCS and GCSR. Most importantly, in pPH patients with pRVEF (n=8) GLS (−26.6% [−22.6 to −27.3] vs. −28.1% [−26.2 to −30.6], p=0.04), sept-LS (−21.2% [−19.8 to −23.2] vs. −26.0% [−24.0 to −27.9], p=0.005), and FAC (39% [35–44] vs. 44% [42–47], p=0.02) were still significantly impaired compared to healthy controls. The RV TTP was significantly increased in pPH patients compared to healthy controls (47% [44–57] vs. 40% [33–43], p≤0.001). Conclusions Several CMR-FT strain parameters of the right ventricle are impaired in pPH patients when compared to healthy controls. Moreover, even in pPH patients with a preserved RVEF multiple RV strain parameters (GLS, sept-LS, and FAC) remained significantly impaired, and TTP significantly prolonged, in comparison to healthy controls. This suggests that RV strain parameters may be used as an early marker of RV dysfunction in pPH patients. Funding Acknowledgement Type of funding source: None

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Chronic thromboembolic pulmonary hypertension (CTEPH) leads to a progressive increase in pulmonary vascular resistance (PVR) and pulmonary artery pressure (PAP) with the development of severe dysfunction of the right heart and heart failure. Mortality for three years with an average pressure in the pulmonary artery (PA) of more than 50 mmHg is more than 90%. Balloon pulmonary angioplasty (BPA) has a significant advantage over other methods of surgical treatment, but it requires the determination of additional non-invasive markers of effectiveness. Transthoracic echocardiography (TTE) remains the main method for assessing the morphology and function of the heart. Purpose Compare different indicators reflecting the severity of CTEPH with TTE indicators before and after BPA. To evaluate the effectiveness of using BPA for the treatment of patients with CTEPH using routine TTE and speckle tracking mode. Materials and methods For 18 months 30 patients without concomitant cardiovascular pathology were subjected to several BPA sessions. Before treatment, 50% of patients belonged to the 3 CTEPH functional class (FC), 40% to 2 FC, 10% to 1 FC. The average number of sessions was 4.7 ± 1.3. Before the first BPA and after the last, all the patients were performed: six-minute walk test (6MWT, metres), Borg scale (in points), test for NT-proBNP (pg/ml); TTE with assessment of the right ventricle (RV) and left ventricle (LV) including areas of the right atrium (aRA, cm2), mean pulmonary artery pressure (PUPM,mmHg),RV free wall strain (GLSFW, %), RV free wall strain rate (GLSRFW, sm/sec), RV free wall postsystolic shortening (PSSFW, %), tricuspid annular plane systolic excursion (TAPSE, sm), tricuspid annulus systolic velocity (TASV, sm/sec). Results. Before the first BPA session, the 6MWT in the patient group averaged 315.9 ± 9.08 metres, after - 439.5 ± 11.45 m; the Borg from 5.4 ± 0.94 points decreased to 4 ± 1.01 points; NT-proBNP before the treatment was 1513 ± 13.01 pg/ml, after - 171 ± 6.09; according to TTE the ratio of RV/ LV before and after treatment was 1.31 ± 0.02 and 0.97 ± 0.04; aRA was 29.3 ± 4.87 and 22.3 ± 3.53 cm2; basal RV - 52 ± 5.11 and 44 ± 7.26 mm; PUPM decreased from 76.6 ± 7.65 to 31.3 ± 3.78 mmHg; GLSFW from -14.69 ± 2.33 came to 17.5 ± 3.45 %; GLSRFW with -0.9 ± 0.09 to -1.7 ± 0.11 cm/sec; TAPSE from 16.7 ± 1.87 to 18.2 ± 2.34 cm; TASV from 10.11 ± 1.45 to 12.25 ± 1.98 cm/s, PSSFW before treatment was -18.4 ± 1.2%, after treatment in 66% of patients disappeared, in 34% became an average of 17.4 ± 0.9% The distribution of STEPH FC has also changed. Conclusion. BPA leads to an improvement in the tolerance of physical activity, clinical indicators, and parameters of central hemodynamics in the pulmonary circulation, evaluated according to direct manometry, and leads to reverse remodeling of the RV in the long term. Performing a staged BPA leads to an improvement in the functional parameters of contractility of the RV.

Introduction. Sickle cell hemoglobin D disease (HbSD) is a rare variant of sickle cell disease (SCD). Incidence of pulmonary thromboembolism (PE) and deep venous thrombosis (DVT) in children with HbSD is unknown. PE and DVT are known complications of SCD in adults but have not been reported in the literature in children with HbSD.Case Report. We are reporting a case of a 12-year-old boy with HbSD with acute chest syndrome (ACS) complicated by complete thrombosis of the branch of the right pulmonary artery and multiple small pulmonary artery emboli seen on computed tomography (CT) pulmonary angiogram and thrombosis of the right brachial vein seen on Doppler ultrasound. Our patient responded to treatment with anticoagulant therapy.Conclusion. There are no cases reported in children with HbSD disease presenting as ACS with pulmonary thromboembolism. We suggest that PE should be suspected in patients presenting with ACS who do not show improvement with standard management. CT pulmonary angiogram should be utilized for early diagnosis and appropriate management as there is no current protocol for management of PE/DVT in pediatric patients with SCD.

To analyze the interaction between the right and left ventricle, we developed a model that consists of three functional elastic compartments (left ventricular free wall, septal, and right ventricular free wall compartments). Using 10 isolated blood-perfused canine hearts, we determined the end-systolic volume elastance of each of these three compartments. The functional septum was by far stiffer for either direction [47.2 +/- 7.2 (SE) mmHg/ml when pushed from left ventricle and 44.6 +/- 6.8 when pushed from right ventricle] than ventricular free walls [6.8 +/- 0.9 mmHg/ml for left ventricle and 2.9 +/- 0.2 for right ventricle]. The model prediction that right-to-left ventricular interaction (GRL) would be about twice as large as left-to-right interaction (GLR) was tested by direct measurement of changes in isovolumic peak pressure in one ventricle while the systolic pressure of the contralateral ventricle was varied. GRL thus measured was about twice GLR (0.146 +/- 0.003 vs. 0.08 +/- 0.001). In a separate protocol the end-systolic pressure-volume relationship (ESPVR) of each ventricle was measured while the contralateral ventricle was alternatively empty and while systolic pressure was maintained at a fixed value. The cross-talk gain was derived by dividing the amount of upward shift of the ESPVR by the systolic pressure difference in the other ventricle. Again GRL measured about twice GLR (0.126 +/- 0.002 vs. 0.065 +/- 0.008). There was no statistical difference between the gains determined by each of the three methods (predicted from the compartment elastances, measured directly, or calculated from shifts in the ESPVR). We conclude that systolic cross-talk gain was twice as large from right to left as from left to right and that the three-compartment volume elastance model is a powerful concept in interpreting ventricular cross talk.

Primary pulmonary angiosarcoma is a rare type of malignant vascular tumour with poor prognosis. Diagnosis is often late due to non-specific symptoms and low clinical suspicion for angiosarcoma. A 72-year-old man presented to hospital with a 6-month history of mild progressive dyspnoea, with associated cough, episodes of presyncope and weight loss. CT pulmonary angiogram (CTPA) was reported as a large saddle pulmonary embolism extending into both the right and left pulmonary arteries. Further Multidisciplinary team meeting (MDM) discussion, and review of CTPA and subsequent investigations revealed a large primary pulmonary artery sarcoma which was later confirmed histology. The patient was referred to the cardiothoracic surgeons and underwent left radical pneumonectomy.

Abstract Introduction Right sided heart failure (RVF) is recognized as a major cause of morbidity and mortality after left ventricular assist device (LVAD) implantation. Despite the publication of several risk scores and predication models, identifying patients at risk for RVF after LVAD implantation remains a challenge. The right ventricle is complex in structure and not possible to fully assess from one echocardiographic 2D plane. Our centre previously introduced a novel multi-plane approach whereby four different RV free wall segments (lateral, anterior, inferior and inferior coronal – figure 1) can be imaged from the same echocardiographic position using electronic plane rotation. Purpose The aim of the study was to determine the feasibility of using multi-plane echocardiography to quantify right ventricular function in a small cohort of advanced heart failure patients prior to LVAD implantation. Methods Twelve advanced heart failure patients underwent detailed RV assessment by multi-plane echocardiography prior to LVAD implantation (median -15 [6.3–29.8] days before). Feasibility and values of the established RV functional echo parameters tricuspid annular plane systolic excursion (TAPSE) and tissue Doppler imaging derived tricuspid annular peak systolic velocity (TDI S') were assessed by an experienced sonographer on each of the 4 free wall segments. Mean values were calculated from an average of 3 measurements. Conventional 2D echo parameters and clinical outcome data post LVAD implantation were also collected. Results Feasibility of TAPSE and TDI measurements in all four RV free wall segments was 100%, with the exception of the inferior coronal wall (91.7% – TDI S' only). Mean 4 wall averaged TAPSE was 13.9±5.1mm, whilst mean TDI S' was 9.4±2.6cm/s. Mean TAPSE and TDI values were lower in the inferior and inferior coronal walls (13.3±5.8mm; 8.8±3.1cm/s and 10.9±5.7mm; 8.9±3.7cm/s) than those of the lateral and anterior walls (15.6±5.1mm; 9.9±2.3cm/s and 15.9±5.1mm; 10.1±2.6cm/s). The cohort was split by using a four wall averaged TAPSE value of 16mm as a cutoff. Mean 4 wall averaged TAPSE was 20.6±1.9mm in the >16mm group compared to 10.5±1.7mm for the <16mm group, whilst mean TDI S' was 9.4±2.6cm/s vs 7.7±0.7cm/s. Post LVAD implantation, there were 3 (25%) deaths and 6 (50%) incidences of acute kidney injury. Median length of stay in ICU and hospital was 4 (1–13.5) and 42.5 (30.3–65) days respectively. The <16mm group had higher incidences of negative outcomes and longer stay in both ICU and hospital following LVAD implantation (p: 0.07). Conclusion Multi-plane echocardiographic evaluation of the right ventricle appears feasible in advanced heart failure with potential for a more comprehensive quantification of right ventricular function pre-LVAD implantation. Larger, ideally multi-centre studies are required to further assess these preliminary findings.
