Telemedicine in Vascular Surgery During COVID-19 Pandemic: A Systematic Review and Narrative Synthesis.

Background: The COVID-19 pandemic resulted in seismic changes to healthcare service delivery. The use of telemedicine was widely adopted during the pandemic, although its value in the safe care of vascular patients is unknown.

Methods: A systematic review was undertaken to identify studies that described outcomes or patient/clinician views of telemedicine (telephone or video) services in vascular surgery during or after the pandemic.

Coronary Thermodilution Waveforms After Acute Reperfused ST-Segment-Elevation Myocardial Infarction: Relation to Microvascular Obstruction and Prognosis.

Background Invasive measures of microvascular resistance in the culprit coronary artery have potential for risk stratification in acute ST-segment-elevation myocardial infarction. We aimed to investigate the pathological and prognostic significance of coronary thermodilution waveforms using a diagnostic guidewire. Methods and Results Coronary thermodilution was measured at the end of percutaneous coronary intervention, (PCI) and contrast-enhanced cardiac magnetic resonance imaging (MRI) was intended on day 2 and 6 months later to assess left ventricular (LV) function and pathology.
