Phased-Array Intracardiac Echocardiography Monitoring During Pulmonary Vein Isolation in Patients With Atrial Fibrillation Impact on Outcome and Complications
Nassir F. Marrouche,David O. Martin,Oussama M. Wazni,A. Marc Gillinov,Allan L. Klein,Mandeep Bhargava,Eduardo B. Saad,Dianna Bash,Hirotsugu Yamada,Wael A. Jaber,Robert A. Schweikert,Patrick J. Tchou,Ahmad Abdul-Karim,Walid Saliba,Andrea Natale +14 more
TL;DR: Intracardiac echocardiography improves the outcome of cooled-tip PVI and power adjustment guided by direct visualization of microbubble formation reduces the risk of PV stenosis and improves long-term cure.
Journal ArticleDOI
Clinical application of pulsed Doppler tissue imaging for assessing abnormal left ventricular relaxation.
Takashi Oki,Tomotsugu Tabata,Hirotsugu Yamada,Tetsuzo Wakatsuki,Hisanori Shinohara,Akiyoshi Nishikado,Arata Iuchi,Nobuo Fukuda,Susumu Ito +8 more
TL;DR: Early diastolic parameters derived from the motion velocity of the LV posterior wall by pulsed Doppler tissue imaging were closely related to the time constant, which may allow noninvasive evaluation of abnormal LV relaxation in patients with various heart diseases.
Journal ArticleDOI
Ventricular untwisting: a temporal link between left ventricular relaxation and suction.
Yuichi Notomi,Zoran B. Popović,Hirotsugu Yamada,Don W. Wallick,Maureen Martin,Stephanie J. Oryszak,Takahiro Shiota,Neil L. Greenberg,James D. Thomas +8 more
TL;DR: The start of LV untwisting coincided with the beginning of relaxation and preceded suction-aided filling resulting from elastic recoil, suggestingUntwisting rate may be a useful marker of diastolic function or even serve as a therapeutic target for improving diastolics function.
Journal ArticleDOI
Assessment of Left Ventricular Torsional Deformation by Doppler Tissue Imaging Validation Study With Tagged Magnetic Resonance Imaging
Yuichi Notomi,Randolph M. Setser,Takahiro Shiota,Maureen G. Martin-Miklovic,Joan A. Weaver,Zoran B. Popović,Hirotsugu Yamada,Neil L. Greenberg,Richard D. White,James D. Thomas +9 more
TL;DR: Testing the accuracy of a novel method that uses Doppler tissue imaging (DTI) for quantifying LV torsion in humans with tagged magnetic resonance imaging (MRI) as a reference has shown that DTI can quantifyLV torsional deformation over time.
Journal ArticleDOI
Role of Left Atrial Appendage in Left Atrial Reservoir Function as Evaluated by Left Atrial Appendage Clamping During Cardiac Surgery
Tomotsugu Tabata,Takashi Oki,Hirotsugu Yamada,Arata Iuchi,Susumu Ito,Takaki Hori,Tetsuya Kitagawa,Itsuo Kato,Hiroshi Kitahata,Shuzo Oshita +9 more
TL;DR: It is concluded that the LAA is more compliant than the LA main chamber, and plays an important role in LA reservoir function in the presence of LA pressure and/or volume overload.
