Using multimodality imaging, we evaluated the impact of PEX on cardiac morphology and function according to the site of maximum compression, and the effect of exertion and breathing.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>All patients underwent chest computed tomography, cardiac magnetic resonance (CMR), and stress echocardiography (echo) in order to establish surgical candidacy. We evaluated diastolic function and trans-tricuspid gradient during stress (echo); and systolic function and respiratory-related septal wall motion abnormalities (CMR). Patients were classified according to the site of cardiac compression as type 0 (without cardiac compression); type 1 (right ventricle); and type 2 [right ventricle and atrioventricular (AV) groove]. Fifty-nine patients underwent multimodality imaging, with a mean age of 19.5\u2009\u00b1\u20095.9 years. Compared with a sex and age matched control group, peak exercise capacity was lower in patients with PEX (8.4\u2009\u00b1\u20092.0 METs vs. 15.1\u2009\u00b1\u20094.6 METs, P\u2009&amp;lt;\u20090.0001). At stress, significant differences were found between groups regarding left ventricular E\/A (P\u2009=\u20090.004) and e\/a ratio (P\u2009=\u20090.005), right ventricular E\/A ratio (P\u2009=\u20090.03), and trans-tricuspid gradient (P\u2009=\u20090.001). At CMR, only 9 (15%) patients with PEX had normal septal motion, whereas 17 (29%) had septal flattening during inspiration. Septal motion abnormalities were significantly related to the cardiac compression classification (P\u2009&amp;lt;\u20090.0001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The present study demonstrated that patients with PEX, particularly those with compression affecting the right ventricle and AV groove, manifest diverse cardiac abnormalities that are mostly related to exertion, inspiration, and diastolic function.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjci\/jez061","type":"journal-article","created":{"date-parts":[[2019,3,12]],"date-time":"2019-03-12T20:12:27Z","timestamp":1552421547000},"page":"77-84","source":"Crossref","is-referenced-by-count":38,"title":["Impact of pectus excavatum on cardiac morphology and function according to the site of maximum compression: effect of physical exertion and respiratory cycle"],"prefix":"10.1093","volume":"21","author":[{"given":"Gaston A","family":"Rodriguez-Granillo","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Imaging, Diagnostico Maipu, Av.
