AI Article Synopsis
- The study investigates heart function in patients with COVID-19 by comparing right ventricular strain during hospitalization and six months post-discharge.
- Researchers analyzed echocardiograms from 43 patients, measuring parameters like right ventricular global longitudinal strain and right atrial reservoir strain.
- Results showed significant improvement in cardiac measures after discharge, suggesting recovery of heart function in those previously hospitalized for non-severe COVID-19.
Article Abstract
Purpose: Those hospitalised with coronavirus disease 2019 (COVID-19) have recently been shown to have impaired right ventricular (RV) strain, but data about the course of heart function after discharge are limited. Our aim was to compare right ventricular strain and right atrial reservoir strain (RASr) associated with COVID-19 between acute disease (during hospitalisation) and follow-up (after discharge).
Methods: In this retrospective single-center study, we analysed the echocardiograms of 43 patients hospitalised for non-severe COVID-19 between December 2020 and March 2021, undergoing echocardiography both during and after hospitalisation. In addition to conventional echocardiographic parameters, we applied 2-dimensional speckle tracking to obtain RV global longitudinal strain (RV-GLS), RV free wall strain (RV-FWS), and RASr.
Results: Mean (standard deviation) age of the study population was 50 (9) years, and 18 (42%) of the participants were women. Median duration between exams was 6 months (range, 5-7 months). Both mean RV-GLS and mean RV-FWS significantly increased at follow-up (-20.8 [3.8] vs. -23.5 [2.8], < 0.001 and -23.3 [4.2] vs. -28.2 [2.8], < 0.001; respectively), and RASr significantly improved as well (-32.3 [6.6] vs. -41.9 [9.8], < 0.001).
Conclusion: In patients hospitalised for non-severe COVID-19 pneumonia, RV-GLS, RV-FWS, and RASr improved significantly between acute disease and 6 months after discharge.

Potential of right ventricular function assessment with echocardiography in transcatheter aortic valve replacement.

Background: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment.

Persistent myocardial impairment proved by histopathologic studies universally existed in patients with Kawasaki disease (KD); however, the long-term effects on myocardial contractile reserve in KD patients, especially on patients without coronary artery lesions (CALs), is still unknown. The aim of this study was to investigate myocardial contractile reserve in KD patients during late convalescent stage by speckle-tracking adenosine triphosphate (AT) echocardiography. A total of 63 antecedent KD patients at least 4 years after the disease onset and 40 age- and gender-matched normal controls were prospectively enrolled.

Background: Imaging both electrical and mechanical cardiac function can better characterize cardiac disease and improve patient care. Currently, there is no noninvasive technique that can simultaneously image both electrical and mechanical function of the whole heart at the point of care. Here, our aim is to demonstrate that high volume-rate echocardiography can simultaneously map cardiac electromechanical activation and end-systolic cardiac strain of the whole heart in a single heartbeat.

Background Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare genetic disorder associated with an elevated risk of life-threatening arrhythmias and progressive ventricular impairment. Risk stratification is essential to prevent major adverse cardiac events (MACE). Our study aimed to investigate the incremental value of strain measured by two-dimensional speckle-tracking echocardiography in predicting MACE in ARVC patients compared to conventional echocardiographic parameters.
