Project description:Iatrogenic valvular regurgitation following cardiac surgery has been reported as a result of leaflet perforation or entrapment. Due to its central location, the aortic valve is one of the most vulnerable structures for iatrogenic injuries. Proper assessment of the aortic valve by transesophageal echocardiography (TEE) should be done after a cardiac surgery in the periaortic area. We hereby report a case of iatrogenic aortic regurgitation which was developed after primary closure of perimembranous ventricular septal defect. It was timely diagnosed by TEE after termination of cardiopulmonary bypass and helped in further management.

Left ventricle segmentation in transesophageal echocardiography images using a deep neural network.

Project description:PurposeThere has been little progress in research on the best anatomical position for effective chest compressions and cardiac function during cardiopulmonary resuscitation (CPR). This study aimed to divide the left ventricle (LV) into segments to determine the best position for effective chest compressions using the LV systolic function seen during CPR.MethodsWe used transesophageal echocardiography images acquired during CPR. A deep neural network with an attention mechanism and a residual feature aggregation module were applied to the images to segment the LV. The results were compared between the proposed model and U-Net.ResultsThe results of the proposed model showed higher performance in most metrics when compared to U-Net: dice coefficient (0.899±0.017 vs. 0.792±0.027, p<0.05); intersection of union (0.822±0.026 vs. 0.668±0.034, p<0.05); recall (0.904±0.023 vs. 0.757±0.037, p<0.05); precision (0.901±0.021 vs. 0.859±0.034, p>0.05). There was a significant difference between the proposed model and U-Net.ConclusionCompared to U-Net, the proposed model showed better performance for all metrics. This model would allow us to evaluate the systolic function of the heart during CPR in greater detail by segmenting the LV more accurately.

Three-dimensional transesophageal echocardiography of the atrial septal defects.

Project description:Transesophageal echocardiography has advantages over transthoracic technique in defining morphology of atrial structures. Even though real time three-dimensional echocardiographic imaging is a reality, the off-line reconstruction technique usually allows to obtain higher spatial resolution images. The purpose of this study was to explore the accuracy of off-line three-dimensional transesophageal echocardiography in a spectrum of atrial septal defects by comparing them with representative anatomic specimens.
