Physical examination revealed rales in both lungs, regular heart sounds without murmurs, clubbing of the toes (Figure 1A), and no pitting edema. Chest X-ray showed cardiomegaly and prominent pulmonary vasculature (Figure 1B). Laboratory findings reported elevated brain natriuretic peptide. Transthoracic echocardiography demonstrated patent ductus arteriosus (PDA) with bidirectional shunting (Figure 2, Supplementary Table 1, Movie 1). Right cardiac catheterization revealed severe pulmonary arterial hypertension (PAH) with right ventricle dysfunction (mean pulmonary artery pressure [PAP]: 78 mmHg, pulmonary capillary wedge pressure: 12 mmHg, pulmonary vascular resistance [PVR]: 27.8 Wood units [WU], Qp/Qs: 1.18, and cardiac output: 4.1 L/min by Fick method). We diagnosed PAH associated with PDA1) and started treatment with oral sildenafil (20 mg) 3 times a day in addition to ambrisentan (5 mg) once a day. We conducted a 15-minute closure test on the PDA by measuring the pressure gradient between the central aorta and PA. A decrease of mean PAP by 15 mmHg was observed without any change in cardiac output (Figure 3, Supplementary Table 1). Finally, we performed PDA closure with an Amplatzer septal occluder (8/6 mm).

However, there are several challenges that need to be addressed before myocardial strain can be widely used in routine clinical practice. One of the main issues is that strain values can vary depending on the software used for measurement, and there is currently no standardization method for correcting these differences. As a result, it can be difficult to compare strain values obtained using different software programs, which can limit the utility of strain measurements in clinical decision-making. As such, the validation of strain measurement software is a critical step in establishing the reliability and accuracy of this tool. As these developments continue, it is likely that myocardial strain measurement will become an increasingly important tool for the diagnosis, treatment, and management of cardiac disease.","PeriodicalId":15229,"journal":{"name":"Journal of Cardiovascular Imaging","volume":"31 3","pages":"142-144"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/4f/95/jcvi-31-142.PMC10374385.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9888885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breathing maneuvers have been utilized as a vasoactive stress test to dynamically characterize myocardial tissue in vivo. We tested the feasibility of sequential, rapid cMRF acquisitions during breathing maneuvers to quantify myocardial T1 and T2 changes. METHODS We measured T1 and T2 values using conventional T1 and T2-mapping techniques (modified look locker inversion [MOLLI] and T2-prepared balanced-steady state free precession), and a 15 heartbeat (15-hb) and rapid 5-hb cMRF sequence in a phantom and in 9 healthy volunteers. The cMRF5-hb sequence was also used to dynamically assess T1 and T2 changes over the course of a vasoactive combined breathing maneuver. RESULTS In healthy volunteers, the mean myocardial T1 of the different mapping methodologies were: MOLLI 1,224 ± 81 ms, cMRF15-hb 1,359 ± 97 ms, and cMRF5-hb 1,357 ± 76 ms. The mean myocardial T2 measured with the conventional mapping technique was 41.7 ± 6.7 ms, while for cMRF15-hb 29.6 ± 5.8 ms and cMRF5-hb 30.5 ± 5.8 ms. T2 was reduced with vasoconstriction (post-hyperventilation compared to a baseline resting state) (30.15 ± 1.53 ms vs. 27.99 ± 2.07 ms, p = 0.02), while T1 did not change with hyperventilation. During the vasodilatory breath-hold, no significant change of myocardial T1 and T2 was observed. CONCLUSIONS cMRF5-hb enables simultaneous mapping of myocardial T1 and T2, and may be used to track dynamic changes of myocardial T1 and T2 during vasoactive combined breathing maneuvers.","PeriodicalId":15229,"journal":{"name":"Journal of Cardiovascular Imaging","volume":"31 2","pages":"71-82"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/43/13/jcvi-31-71.PMC10133810.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9395787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
