However, the data on the relations between the LV parameters and the development of pulmonary hypertension (PH) in severe AS is lacking. Our objectives were to evaluate the CMR-derived changes of the LV size, morphology, and function in patients with isolated severe AS and PH, and to investigate the prognostic impact of these parameters on elevated systolic pulmonary artery pressure (sPAP). Materials and Methods: Thirty patients with isolated severe AS (aortic valve area \u22641 cm2) underwent a 2D-echocardiography (2D echo) and CMR before aortic valve replacement. Indices of the LV mass and volumes and ejection fraction were analyzed by CMR. The LV global longitudinal (LV LGS) and circumferential strain (LV CS) were calculated using CMR feature tracking (CMR-FT) software (Medis Suite QStrain 2.0, Medis Medical Imaging Systems B.V., Leiden, The Netherlands). The LV fibrosis expansion was assessed using a late gadolinium enhancement sequence. PH was defined as having an estimated sPAP of \u226545 mm Hg. The statistical analysis as performed using SPSS version 23.0 (SPSS, Chicago, IL, USA) Results: 30 patients with severe AS were included in the study, 23% with severe isolated AS had PH (mean sPAP 55 \u00b1 6.6 mm Hg). More severe LV anatomical and functional abnormalities were observed in patients with PH when compared with patients without PH\u2014a higher LV end-diastolic volume index (EDVi) (140 [120.0\u2013160.0] vs. 90.0 mL\/m\u00b2 [82.5\u2013103.0], p = 0.04), larger LV fibrosis area (7.8 [5.6\u20138.0] vs. 1.3% [1.2\u20131.5], p = 0.005), as well as lower LV global longitudinal strain (GLS; \u221214.0 [\u221214.9\u2013(\u22128.9)] vs. \u221221.1% [\u221223.4\u2013(\u221217.8)], p = 0.004). By receiver\u2013operating characteristic (ROC) curve analysis, LV EDVi &gt; 107.7 mL\/m\u00b2 (Area Under the Curve (AUC) 95.7%), LV GLS &lt; \u221215.5% (AUC 86.3%), and LV fibrosis area &gt;5% (AUC 89.3) were found to be robust predictors of PH in severe AS patients. Conclusions: In patients with severe aortic stenosis, a larger end-diastolic LV volume, impaired LV global longitudinal strain, and larger LV fibrosis extent can predict the development of pulmonary hypertension.<\/jats:p>","DOI":"10.3390\/medicina55100711","type":"journal-article","created":{"date-parts":[[2019,10,23]],"date-time":"2019-10-23T11:46:59Z","timestamp":1571831219000},"page":"711","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Left Ventricular Morphology and Function as a Determinant of Pulmonary Hypertension in Patients with Severe Aortic Stenosis: Cardiovascular Magnetic Resonance Imaging Study"],"prefix":"10.3390","volume":"55","author":[{"given":"Birute","family":"Gumauskiene","sequence":"first","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3020-2810","authenticated-orcid":false,"given":"Lina","family":"Padervinskiene","sequence":"additional","affiliation":[{"name":"Department of Radiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jolanta Justina","family":"Vaskelyte","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Audrone","family":"Vaitiekiene","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7726-6948","authenticated-orcid":false,"given":"Tomas","family":"Lapinskas","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deimante","family":"Hoppenot","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Skaidrius","family":"Miliauskas","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gryte","family":"Galnaitiene","sequence":"additional","affiliation":[{"name":"Department of Radiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulius","family":"Simkus","sequence":"additional","affiliation":[{"name":"Department of Radiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Egle","family":"Ereminiene","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"549","DOI":"10.1510\/icvts.2009.218040","article-title":"Short- and mid-term results for aortic valve replacement in octogenarians","volume":"10","author":"Answers","year":"2010","journal-title":"Interact.
