The output settings of echocardiographic systems should be set to the full (original) frame rate and lossless compression (e.g., run-length encoding) in order to transmit echocardiographic videos so that they retain their original quality. In addition, monitors and display cards of echocardiography systems and workstations should be able to support an adaptive refresh rate for displaying video at an arbitrary frame rate, including a high frame rate (90+ fps) without dropping frames and preserving the original frame duration. Currently, the only available option for echocardiography monitors is 144–165 Hz (or higher) based on adaptive frame rate G-Sync or FreeSync technology monitors. These monitors should be accompanied by compatible display cards. Echocardiography systems and workstation video playback software should support G-Sync or FreeSync adaptive frame rate technology to display echocardiography videos at their original frame rates without the effects of jitter and frame drops. Echocardiography systems should support an online display of the videos on the workstations during acquisition with the original quality. The requirements for web-based workstations are the same as for desktops workstations. Hospital digital networks should provide transmission and long-term archiving of the echocardiographic videos in their original acquisition quality.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, distinct pulmonary vascular disease, which is caused by chronic obstruction of major pulmonary arteries. CTEPH can be cured by pulmonary endarterectomy (PEA). PEA for CTEPH is a challenging procedure, and patient selection and the perioperative management are complex, requiring significant experience.
Objectives: To describe the establishment of a national CTEPH–PEA center in Israel and present results of surgery.
Methods: In this study, we reviewed the outcomes of PEA in a national referral, multi-disciplinary center for CTEPH–PEA. The center was established by collaborating with a high-volume center in Europe. A multidisciplinary team from our hospital (pulmonary hypertension specialist, cardiac surgeon, cardiac anesthesiologist and cardiac surgery intensivist was trained under the guidance of an experienced team from the European center.
Results: A total of 38 PEA procedures were performed between 2008 and 2018. We included 28 cases in this analysis for which long-term follow-up data were available. There were two hospital deaths (7%). At follow-up, median New York Heart Association (NYHA) class improved from III to I (P < 0.0001), median systolic pulmonary pressure decreased from 64 mmHg to 26 mmHg (P < 0.0001), and significant improvements were seen in right ventricular function and exercise capacity.
Conclusions: A national center for performance of a rare and complex surgical procedure can be successfully established by collaboration with a high-volume center and by training a dedicated multidisciplinary team.

Background: Implant-related spinal infections are a surgical complication associated with high morbidity. Due to infection, hardware removal may be necessary, which could lead to pseudarthrosis and the loss of stability and alignment.
Objectives: To evaluate the accuracy and diagnostic value of 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG PET/CT) in the workup of patients with suspected implant-related infections of the spine and to assess the clinical impact of PET/CT results on the management of these infections.
Methods: The study included nine consecutive patients with a history of spinal surgery who underwent PET/CT for evaluation of suspected spinal implant related infection. All imaging studies were performed between January 2011 and December 2013. All 18F-FDG PET/CT scans were performed on an 8 slice PET/CT following an 18F-FDG injection. Images were scored both visually and semi-quantitatively by a radiology expert. Results were compared to additional imaging studies when available, which were correlated to clinical and bacteriological findings allowing calculation of sensitivity, specificity and accuracy.
Results: Among the patients, five experienced hardware-related spinal infection. 18F-FDG PET/CT sensitivity was 80%, specificity 100%, and accuracy 88.9%. One scan produced a false negative; however, a second PET/CT scan revealed an infection.
Conclusions: PET/CT was found to be valuable for the diagnosis of postoperative hardware-related spinal infection, especially when other imaging modalities were uninformative or inconclusive. As such, PET/CT could be useful for management of infection treatment.

Spinal manipulation therapy (SMT) is commonly used as an effective therapeutic modality for a range of cervical symptoms. However, in rare cases, cervical manipulation may be associated with complications. In this review we present a series of cases with cervical spine injury and myelopathy following therapeutic manipulation of the neck, and examine their clinical course and neurological outcome. We conducted a search for patients who developed neurological symptoms due to cervical spinal cord injury following neck SMT in the database of a spinal unit in a tertiary hospital between the years 2008 and 2018. Patients were assessed for the clinical course and deterioration, type of manipulation used and subsequent management. A total of four patients were identified, two men and two women, aged 32–66 years. In three patients neurological deterioration appeared after chiropractic adjustment and in one patient after tuina therapy. Three patients were managed with anterior cervical discectomy and fusion while one patient declined surgical treatment. Assessment for subjective and objective evidence of cervical myelopathy should be performed prior to cervical manipulation, and suspected myelopathic patients should be sent for further workup by a specialist familiar with cervical myelopathy (such as a neurologist, a neurosurgeon or orthopedic surgeon who specializes in spinal surgery). Nevertheless, manipulation therapy remains an important and generally safe treatment modality for a variety of cervical complaints. This review does not intend to discard the role of SMT as a significant part in the management of patients with neck related symptoms, rather it is meant to draw attention to the need for careful clinical and imaging investigation before treatment.
