Pulmonary metastatic chondrosarcoma with massive extension into left atrium and left ventricle: outcome of surgical management in emergency

Abstract Introduction Various minimally invasive mitral valve (MV) repair techniques are available to treat degenerative mitral regurgitation (MR). Transapical implantation of artificial chordae on a beating heart is performed using the NeoChord DS1000 device with real-time TEE guidance. Purpose 1)To assess preoperative and the mid-term follow-up echocardiographic data in patients after MV repair using the NeoChord DS1000 device; 2)to investigate the changes of left ventricle (LV), left atrium (LA) and mitral annulus dimensions during the follow-up period; 3)to assess the difference of baseline echocardiographic parameters between successful and not-successful (severe residual MR) MV repair groups; 4)to identify the preoperative echocardiographic variables that may be associated with recurrence of MR at mid-term follow. Methods All patients after transapical MV repair with Neochord implantation in Vilnius University hospital were prospectively entered into the study. The acquired preoperative and follow-up echocardiographic datasets were analysed. According to the residual MR at follow-up, patients were stratified to 2 groups: group A – successful durable MV repair (residual MR ≤2); group B – MV repair failure (recurrence of severe MR or reintervention). Values were expressed as Mean±SD. Univariable regression analysis was used to identify anatomical predictors of residual MR. Results 53 (70.67%) patients had a residual MR ≤2 (Group A) and 22 (29.33%) residual MR≥2+ (Group B) at 26±6 months follow-up. At baseline, Group B patients had significantly larger left ventricle end diastolic diameter (LVEDD) (mean difference 5.67±1.29mm, p<0.0001) left ventricle end systolic diameter (LVESD) (mean difference 4.08±1.57mm, p=0.012), LA volume index (mean difference 21.57±5.003 p<0.0001) and higher systolic pulmonary pressure values (mean difference 10.46±3.34, p<0.003) compared with group A. Overall, a significant reduction in LA volume index (mean change 15.69±4.15ml/m2, p<0.001), LA diameter (mean change 3.15±1.24, p=0.012), LV diameter (mean change in LVEDD 4.78±0.88mm p<0.000) was observed at 24 months follow up. There was no significant changes in MV annular parameters at follow up. Left atrium volume (OR 1.018; 95% CI 1.006–1.035; p=0.009), left atrium volume index (OR 1.038; 95% CI 1.013–1.072; p=0.010), LVEDD (OR 1.201; 95% CI 1.088–1.353; p=0.0008), LVESD (OR 1.122; 95% CI 1.02–1.248); p=0.0236) and sPAP (OR 1.418; 95% CI 1.139–2.016; p=0.0014) were all significantly associated with the worse outcome (MR >2) after mini-invasive MV repair in univariable regression analysis. Conclusions Minimaly invasive MV repair with Neochord system on beating heart is effective in patients with degenerative MR. Baseline echocardiographic characteristics predictive for a worse middle term outcome are mainly related to LV and LA remodeling. Reverse remodeling of LV and LA is observed during the follow-up period with no significant changes in MV annulus. Funding Acknowledgement Type of funding source: None

High Level

Endomyocardial fibrosis is a rare cardiomyopathy. There has to be a high level of suspicion to make the diagnosis. The treatment is based on symptomatic relief and surgical management is based on the exact pathology found in the left ventricle apex. MRI is a robust investigation which can confirm diagnosis and provide management options and prognosis.

Cascaded Regression

The creation of 3D models for cardiac mapping systems is time-consuming, and the models suffer from issues with repeatability among operators. The present study aimed to construct a double-shaped model composed of the left ventricle and left atrium. We developed cascaded-regression-based segmentation software with probabilistic point and appearance correspondence. Group-wise registration of point sets constructs the point correspondence from probabilistic matches, and the proposed method also calculates appearance correspondence from these probabilistic matches. Final point correspondence of group-wise registration constructed independently for three surfaces of the double-shaped model. Stochastic appearance selection of cascaded regression enables the effective construction in the aspect of memory usage and computation time. The two correspondence construction methods of active appearance models were compared in terms of the paired segmentation of the left atrium (LA) and left ventricle (LV). The proposed method segmented 35 cardiac CTs in six-fold cross-validation, and the symmetric surface distance (SSD), Hausdorff distance (HD), and Dice coefficient (DC), were used for evaluation. The proposed method produced 1.88 ± 0.37 mm of LV SSD, 2.25 ± 0.51 mm* of LA SSD, and 2.06 ± 0.34 mm* of the left heart (LH) SSD. Additionally, DC was 80.45% ± 4.27%***, where * p < 0.05, ** p < 0.01, and *** p < 0.001. All p values derive from paired t-tests comparing iterative closest registration with the proposed method. In conclusion, the authors developed a cascaded regression framework for 3D cardiac CT segmentation.

Abstract Funding Acknowledgements Type of funding sources: None. Background. New COVID-19 disease is well known by its primary damage of respiratory system. However, it is also possible to involve other organs and systems. Purpose. To determine the cardiac involvement in patients with COVID-19 pneumonia. Materials and methods. We performed echocardiography with speckle tracking in 48 patients. All of them had serologically verified COVID-19 pneumonia with lung involvement 5-60% on CT. None of them were treated by antimalarial drugs. 28 of them were men and 20 women, mean age - 45 ± 4,4 years old. We performed echocardiography in 1 month period from onset of the disease. Results. Most of the patients (30 patients) had enlargement of right heart chambers. Despite of right ventricle enlargement, in none of the patients had reduced right ventricle function (TAPSE 22 ± 2 mm, right ventricle strain -21,2 ± 1,5%). The mean systolic pulmonary artery pressure was slightly elevated (38 ± 2 mm Hg). Left ventricle was enlarged in 9 patients (with mean end diastolic volume 82 ± 5 ml/m2). In 25 of them, the ejection fraction was decreased (44 ± 4%). In all patients with COVID-19 pneumonia, the changes in circumferential and longitudinal strain were observed. Both parameters were decreased. The mean value of circumferential strain was -16,3 ± 1,9%. The longitudinal strain parameter was -14,2 ± 1,4%. 25 patients had enlargement of left atrium (>40ml/m2) and the reservoir strain of left atrium was decreased (-23,3 ± 1,5%) in 29 of them. After 2 months from the onset of the disease, we noticed the normalization of echocardiography data in all patients. Nevertheless, we observed cardiac structural and functional changes in all patients, troponins levels were increased only in 12 patients. Conclusion. We observed cardiac involvement in different degree in all of patients with COVID-19 pneumonia. Changes characterized by atriums and ventricles enlargement, and left ventricle contractile dysfunction. Due to the fact that only part of the patients with COVID-19 with cardiac changes had elevated troponins, we believe that the mechanism of these pathological changes need further research.
