Background Previous studies demonstrated that left atrium (LA) size is associated with mortality in an elderly population. It remains unclear whether indices of LA function including reservoir, conduit, or booster elements of LA function provide incremental prognostic information. Hypothesis Echocardiographic measures of the various parameters of LA function would predict 5‐year mortality in a community‐dwelling population of 85 to 86 year olds independently of LA volume. Methods Subjects ages 85 to 86 years old underwent home echocardiography. LA volumes were assessed by the biplane Simpson's method from apical views using measurements of phasic volumes and functions of the LA, including LA expansion index. LA passive and active emptying fractions were assessed. Survival status at 5‐year follow‐up was assessed. Results Two hundred eighty‐two subjects were included, of whom 87 (31%) had died at follow‐up. Survival of the subjects in the lowest quartile of the LA expansion index as well as LA active filling index was significantly lower. When measurements of LA volume index were added to the model, the relationship between survival and indices of LA function remained significant. Conclusions This study demonstrated that elderly subjects aged 85 to 86 years with significantly impaired LA function had increased 5‐year mortality independently of indices of LA volume.

Atypical presentations of ST-segment-elevation myocardial infarction (STEMI) have been reported in patients who have COVID-19. We have seen this occurrence in our center in Bronx, New York, where multitudes of patients sought treatment for the coronavirus. We studied the prevalence of atypical STEMI findings among patients with COVID-19 who presented during the first 2 months of the pandemic. Consistent with previous reports, 4 of our 10 patients with COVID-19 and STEMI had no identifiable culprit coronary lesion; rather, they often had diffuse ST-segment elevations on surface electrocardiograms along with higher levels of D-dimer and inflammatory markers. In contrast, 32 of 33 patients without COVID-19 (97%) had a culprit lesion. The patients with COVID-19 and a culprit lesion more often needed thrombectomy catheterization and administration of glycoprotein IIb/IIIa inhibitors. Our study confirms that patients with COVID-19 often have atypical STEMI presentations, including the frequent absence of a culprit coronary lesion. Our findings can help clinicians prepare for these atypical clinical presentations.

: Pulmonary embolism (PE) is the third leading cause of cardiovascular mortality. Patients with PE can present with a wide array of symptoms, ranging from mild to life threatening. The mainstay of PE treatment is anticoagulation; however, there are many advanced options available for more severe patients, including catheter-directed interventions, surgical treatments, and hemodynamic support. Although different risk scores and clinical guidelines exist, the primary treating teams are frequently left uncertain on the most suitable treatment for a specific complex patient. Pulmonary Embolism Response Teams (PERT), composed of multidisciplinary experts, have emerged and been implemented in many centers and are available 24 hours a day to help guide the primary team. PERTs have changed the way complex PE patients are managed. In centers with a PERT, teams are called upon very frequently and there is a significant increase in the use of advanced treatments for PE, although there are differences between centers based upon the center's specific PERT protocol and available capabilities. As PE is an evolving area, and more studies are necessary, PERTs around the world can help advance the field and improve the treatment offered to PE patients.
