Alternation in left ventricular end-diastolic and end-systolic diameters, systolic diameter shortening, diastolic ventricular filling, systolic ejection time and diastolic period (A2Q) were seen. In addition, two features were noted which have not been previously reported: (1) Alternation in the timing of mitral valve motion, such that prior to the weak beats, closure of the mitral valve did not occur until 40-70 msec. after the onset of the Q-wave on the ECG. Before the strong beats, however, mitral closure coincided approximately with the Q-wave. (2) Alternation of the movement of the interventricular septum with abnormal or paradoxical movement during weak beats and normal movement during the strong beats. The first observation lends credence to the theory that stretch-tension relationships are important in the maintenance of pulsus alternans in some patients. The paradoxical septal motion during the weak beats may be due either to a discordant right and left ventricular alternans or alternate contractile defection of the septum.</p>","PeriodicalId":75677,"journal":{"name":"Cardiovascular Research Center bulletin","volume":"14 4","pages":"83-92"},"PeriodicalIF":0.0,"publicationDate":"1976-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12131528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine the angiographic and hemodynamic correlates of these deficits, right heart catheterization with selective pulmonary angiography was carried out in 7 addicts with abnormal lung scans, and one with normal scan. Four had angiographic abnormalities corresponding to the regions of perfusion defects on lung scan. These consisted of large vessel cut-offs, intraluminal filling defects and/or considerably reduced vascularity. Three subjects had normal angiograms in the presence of abnormal perfusion scans. One subject had normal angiogram and scan. All eight patients had normal pulmonary artery pressures and calculated pulmonary vascular resistances. This study demonstrates that (1) angiographic abnormalities in larger pulmonary arteries may be found in narcotic addicts with perfusion defects on lung scanning, and (2) these findings may be present without significant hemodynamic alterations.</p>","PeriodicalId":75677,"journal":{"name":"Cardiovascular Research Center bulletin","volume":"14 4","pages":"93-100"},"PeriodicalIF":0.0,"publicationDate":"1976-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12131529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
