Journal ArticleDOI
Normal values and clinical relevance of left atrial myocardial function analysed by speckle-tracking echocardiography: multicentre study
Daniel A. Morris,Masaaki Takeuchi,Maximilian Krisper,Clemens Köhncke,Tarek Bekfani,T. Carstensen,Sabine Hassfeld,Marc Dorenkamp,Kyoko Otani,Kiyohiro Takigiku,Chisato Izumi,Satoshi Yuda,Konomi Sakata,Nobuyuki Ohte,Kazuaki Tanabe,Engin Osmanoglou,York Kühnle,Hans-Dirk Düngen,Satoshi Nakatani,Yutaka Otsuji,Wilhelm Haverkamp,Leif-Hendrik Boldt +21 more
TL;DR: The normal range and the clinical relevance of the myocardial function of the LA using 2DSTE have been determined and it was found that the functional class (dyspnoea-NYHA classification) was inversely related to both LA-Strain and LA-SRa.
Journal ArticleDOI
Prognostic Value of Right Ventricular Ejection Fraction Assessed by Transthoracic 3D Echocardiography.
Yasufumi Nagata,Victor Chien-Chia Wu,Yuichiro Kado,Kyoko Otani,Fen-Chiung Lin,Yutaka Otsuji,Kazuaki Negishi,Masaaki Takeuchi +7 more
TL;DR: 3DTTE-determined RV ejection fraction was independently associated with cardiac outcomes in patients with diverse backgrounds and offered incremental value over clinical risk factors and the other echocardiographic parameters including left ventricular systolic and diastolic function for predicting future adverse outcome.
Journal ArticleDOI
Assessment of the aortic root using real-time 3D transesophageal echocardiography.
Kyoko Otani,Masaaki Takeuchi,Kyoko Kaku,Lissa Sugeng,Hidetoshi Yoshitani,Nobuhiko Haruki,Toshiyuki Ota,Victor Mor-Avi,Roberto M. Lang,Yutaka Otsuji +9 more
TL;DR: The geometry of the aortic annulus can be reliably evaluated using 3DTEE as an alternative to MDCT for the assessment of aorta root, and correlated well between the 2 modalities.
Journal ArticleDOI
Prognostic value of LA volumes assessed by transthoracic 3D echocardiography: comparison with 2D echocardiography.
Victor Chien-Chia Wu,Masaaki Takeuchi,Hiroshi Kuwaki,Mai Iwataki,Yasufumi Nagata,Kyoko Otani,Nobuhiko Haruki,Hidetoshi Yoshitani,Masahito Tamura,Haruhiko Abe,Kazuaki Negishi,Fen-Chiung Lin,Yutaka Otsuji +12 more
TL;DR: It is shown that minimal left atrial volume index (LAVImin) by 3-dimensional echocardiography (3DE) is the best predictor of future cardiovascular events and 3D-derived LAVImin had the highest risk ratio.
Journal ArticleDOI
Three-dimensional echocardiographic quantification of the left-heart chambers using an automated adaptive analytics algorithm: multicentre validation study.
Diego Medvedofsky,Victor Mor-Avi,Mihaela Silvia Amzulescu,Covadonga Fernández-Golfín,Rocio Hinojar,Mark J. Monaghan,Kyoko Otani,Joseph Reiken,Masaaki Takeuchi,Wendy Tsang,Jean-Louis Vanoverschelde,Mathivathana Indrajith,Lynn Weinert,José Luis Zamorano,Roberto M. Lang +14 more
TL;DR: Automated 3DE analysis of left-heart chambers is an accurate alternative to conventional manual methodology, which yields almost the same values across laboratories and is more reproducible than manual measurements.
