Currently, surgical removal remains the main clinical treatment for cardiac tumor patients. However, malignant tumors are hard to completely resect. Also, as thoracoscopic surgeries induce...
Hypertrophic obstructive cardiomyopathy (HOCM) patients often develop disabling symptoms of heart failure. Current treatment strategies are predicated on the empirical use of long-standing...
This is an observational study to evaluate the role of a Bed side Focus assessed Transthoracic Echocardiography (FATE) in identifying the patients at a potential risk of developing hypoten...
Increasing evidences suggest that dexmedetomidine pharmacokinetic are different in children. The investigators performed a two-stage study to determine the ED50 and the ED95 of intranasal ...
The main purpose of this study is to evaluate the safety and efficacy of focal (targeted) Radio-Frequency Ablation (RFA) in men with low or intermediate-risk, clinically localized prostate...
Whether echocardiography platform and analysis software impact left ventricular (LV) volumes, ejection fraction (EF), and stroke volume (SV) by transthoracic tridimensional echocardiography (3DE) has ...
Echocardiography Guided Liwen Procedure for the treatment of obstructive hypertrophic cardiomyopathy in a patient with prior aortic valve replacement surgery: Liwen procedure for intra-myocardial radiofrequency ablation.
We successfully treated a patient who was diagnosed of having hypertrophic obstructive cardiomyopathy after the aortic valve replacement surgery for the concomitant aortic stenosis. We report this fir...
Focused training in transthoracic echocardiography enables emergency physicians (EPs) to accurately estimate the left ventricular function. This study aimed to evaluate the efficacy of a brief trainin...
Image-guided ablation of thyroid disease is increasingly being commonly reported. Techniques including ethanol injection and thermal ablation using radio-frequency, laser, and microwave devices have b...
Electromagnetic waves with frequencies between about 3 kilohertz (very low frequency - VLF) and 300,000 megahertz (extremely high frequency - EHF). They are used in television and radio broadcasting, land and satellite communications systems, radionavigation, radiolocation, and DIATHERMY. The highest frequency radio waves are MICROWAVES.
Machine readable patient or equipment identification device using radio frequency from 125 kHz to 5.8 Ghz.
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.
A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues.
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
