Abstract
OBJECTIVE The current work was designed to compare the effects of ciprofol and propofol on left ventricular systolic function and myocardial work by noninvasive speckle-tracking echocardiography in children undergoing surgical repair of atrial septal or ventricular septal defects. DESIGN A single-center double-blind randomized noninferiority study was conducted. SETTING The research occurred at a tertiary care center affiliated with Shanghai Jiao Tong University, China. PARTICIPANTS One hundred and twelve children aged 1 month to 16 years undergoing atrial septal or ventricular septal defect surgery with cardiopulmonary bypass were included. INTERVENTIONS One hundred and twelve children were allocated randomly to receive ciprofol (n = 67) or propofol (n = 45) in a 1.5:1 ratio. Ciprofol or propofol were intravenously infused at loading doses of 0.4 mg/kg or 2.0 mg/kg, respectively, over 30 seconds, depending on the physical condition of each patient. When the bispectral index was maintained between 45 and 55 after induction, transthoracic echocardiography, including apical two-chamber, three-chamber, and four-chamber views, were collected bedside. MEASUREMENTS AND MAIN RESULTS Of the 112 patients enrolled, 104 completed the study. Global longitudinal strain in the ciprofol and propofol groups after anesthesia was -17.3% (95% confidence interval [CI] -18.0% to -16.6%) and -17.8% (95% CI -18.7 to -17.0%) in the full analysis set and -17.5% (95% CI -18.2% to -16.9%) and -17.8% (95% CI -18.7% to -17.0%) in the per-protocol set, respectively. The noninferiority margin was set at 2% and confirmed with a lower limit of two-sided 95% CI for the intergroup difference of 1.58% in the full analysis set and 1.34% in the per-protocol set. There were no significant differences between the groups in left ventricular systolic and diastolic function and myocardial work indices. Postoperative vasoactive-inotropic score, NT-proBNP, duration of mechanical ventilation, and the length of stay in the cardiac intensive care unit and hospital were also comparable between the two groups (all p > 0.05). CONCLUSIONS Ciprofol did not show different effects on myocardial function and postoperative outcomes from propofol. Further, on the sensitive cardiac systole marker global longitudinal strain, ciprofol demonstrated noninferiority to propofol. Ciprofol might be an alternative solution for cardiac anesthesia in children with congestive heart disease with mild lesion.

Abstract
The noninvasive assessment of ventricular function is an ongoing challenge, with new tools and measurements always being considered and tested. The noninvasive assessment of myocardial work via the pressure-strain relationship is one of the newer tools proposed to evaluate ventricular systolic function. However, prior to using any new tool, one should understand its properties, utility, and limitations. In this commentary we focus on the noninvasive assessment of myocardial work via the pressure-strain relationship from a pediatric point of view. We address the current knowledge and limitations and propose future directions to better understand this tool.

Anthracycline-induced cardiotoxicity on regional myocardial work and left ventricular mechanical dispersion in adolescents and young adults in post-lymphoma remission. Cancer Med 2024; 13:e6857. [PMID: 38204211 PMCID: PMC10904967 DOI: 10.1002/cam4.6857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 11/28/2023] [Accepted: 12/10/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND Myocardial work (MW) is a new echocardiographic tool with a high sensitivity to detect early and subtle alterations of myocardial function. We aimed to evaluate the late effects of anthracyclines by assessing the global and segmental MW and intraventricular mechanical dispersion from speckle tracking echocardiography in childhood lymphoma survivors (CLS). METHODS Thirty-one young adults including CLS and age-matched healthy controls were enrolled. All underwent echocardiography including an evaluation of left ventricular (LV) morphology and regional function. We assessed LV longitudinal (differentiating sub-endocardial and sub-epicardial layers), circumferential strains and twist, global and regional MW index (MWI). LV mechanical dispersion was assessed from the time dispersion of LV longitudinal strain, from myocardial wasted work (MWW) and myocardial work efficiency (MWE). RESULTS The longitudinal strains both at the level of the sub-endocardium and sub-epicardium were reduced in CLS compared to controls. The global MWI was also decreased (1668 ± 266 vs 1870 ± 264%.mmHg in CLS patients and controls, respectively, p < 0.05), especially on the apical segments. An increase of LV intraventricular mechanical dispersion was observed in CLS. MWW and MWE remained unchanged compared to controls. CONCLUSION Our results strongly support that cardiac remodeling is observed in CLS, characterized by a decrease in MW and an increase in LV mechanical dispersion. The apex is specifically altered, but its clinical significance remains uncertain. MW as a complement to strain seems interesting in cancer survivors to detect myocardial dysfunction at early stage and adapt their follow-up.

Left bundle branch pacing on mechanical synchrony and myocardial work in bradycardia patients. Int J Cardiovasc Imaging 2023; 39:369-378. [PMID: 36322262 DOI: 10.1007/s10554-022-02742-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 10/01/2022] [Indexed: 11/07/2022]
Abstract
Left bundle branch pacing (LBBP) has emerged as a novel physiological pacing method to produce narrower QRS duration, but whether it could restore mechanical synchrony and improve myocardial work still lacks sufficient evidence. Therefore, the goal of this study was to evaluate mechanical synchrony and myocardial work in LBBP. We collected 20 patients with LBBP due to symptomatic bradycardia and another 29 age-matched patients with right ventricular pacing (RVP). For LBBP patients, cardiac electro-mechanical synchrony and myocardial work were measured at baseline and 7 days after implantation and compared with the RVP patients. In the LBBP group, paced QRS duration and mechanical synchrony were not significantly different from baseline(all P > 0.05), but significantly smaller than that in the RVP group (all P<0.05). Meanwhile, global longitudinal strain (GLS) in LBBP was greater than that in the RVP group (17.7 ± 3.5% vs. 14.8 ± 3.1%, P < 0.05). Global myocardial work index and global constructive work were also better than that in the RVP group(all P<0.05). Global work efficiency was 91.9 ± 3.1%, which was greater when compared with RVP (P < 0.05). LBBP provides better cardiac electro-mechanical synchrony and more effective myocardial work than that in RVP, thus improving global heart function.

J Clin Hypertens (Greenwich) 2022; 24:1547-1557.

Abstract
The study was mainly to evaluate the changes of left ventricular (LV) myocardial work (MW) in children with CKD stage 5 within 3 months after kidney transplantation (KTx). Forty-three successful KTx recipients (mean age 10.6 years, 58% male) in childhood and 28 healthy children were enrolled. General clinical characteristics and laboratory parameters were collected. Cardiac structure, function, and LV MW were assessed by echocardiography before and after KTx. The results showed that significantly improvement was observed in LV global MW index (GWI), constructive MW (GCW), and wasted MW (GWW) (p < .01), but not in MW efficiency (GWE) and global longitudinal strain (GLS) (p > .05). Besides, blood pressure (BP), renal graft function, LV ejection fraction (LVEF), and LV mass index (LVMi) had obviously improved after KTx (p < .05). Nevertheless, compared with healthy children, higher BP, LVMi, GWW, more deteriorated LV diastolic function and lower GWE were still observed in patients after KTx. The ratio of dialysis duration to CKD course were negatively correlated with the improvements of GWE (p = .004), GWI (p = .01), and GCW (p = .01). In conclusion, a portion of LV MW parameters were obviously improved in children received KTx. Thus, LV MW was superior to GLS in evaluating LV systolic function recovery in these patients. Those patients with insignificant MW improvement should be closely monitored, and adjusted the treatment strategies timely to avoid serious and irreversible myocardial injury after KTx.
