We aimed to explore the myocardial functional reserve in adolescent patients with Fontan circulation in response to exercise or acute preload increase.</p><p><strong>Methods: </strong>Our study comprised 32 patients (median age: 16.7 years, range: 15.4-17.9 years, 12 females) with Fontan circulation. Echocardiographic imaging was performed during exercise using a recumbent cycle ergometer and during heart catheterization with a rapid infusion of 0.9% saline infusion at 5 mL/kg body weight. We measured myocardial peak longitudinal strain (LS) in a 4-chamber view during specific time intervals before, during, and after the exercise (LS_stress) and volume load (LS_cath). During catheterization, central venous pressure (CVP) and ventricular end-diastolic pressures (VEDP) were simultaneously recorded. A control group of 16 healthy individuals participated in the exercise test.</p><p><strong>Results: </strong>The mean LS_stress was less negative for patients than for controls (P≤0.001 at all stages); however, it significantly improved from -18.4±5.5% at baseline to -22.0±6.5% (P=0.004) at maximal loading. LS_stress at maximal loading did not correlate with changes in heart rate. During catheterization, the mean LS_cath was -19.6±6.0% at baseline and did not improve significantly at 1.00-2.00 min and at 4.00-6.00 min after saline infusion. In more than half of the patients, LS_cath worsened or improved with less than -2% after the saline infusion. Worsening in LS_cath correlated with CVP and VEDP in all conditions (P≤0.017). There was no difference in LS_stress or LS_cath between the morphological right ventricle and the morphological left ventricle.</p><p><strong>Conclusion: </strong>Patients with Fontan circulation demonstrate systolic myocardial functional reserve that can be recruited with exercise stress but not with an acute increase in preload.</p>","PeriodicalId":50011,"journal":{"name":"Journal of the American Society of Echocardiography","volume":" ","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using time-dependent ROC curves, the parameters obtained from the corrected PISA were more closely associated with outcomes at two years than those obtained with the conventional PISA: EROAc vs. EROA (p<0.001), RegVolc vs. RegVol (p=0.001), and RegFrc vs. RegFr (p<0.001) in ventricular STR.
