3. Dobutamine echocardiography for evaluating coronary artery disease

Author

Clarke, Gregory B. and Sawada, Stephen G.

Subjects
Dobutamine, Echocardiography, Coronary heart disease -- Diagnosis, Health
Abstract

Safe, accurate, and comparatively inexpensive, dobutamine stress echocardiography is an excellent alternative to exercise testing. Its clinical applications include detecting coronary artery disease and preoperative and post-myocardial infarction (MI) risk stratification. Dobutamine stress echocardiography has shown promise in assessing stunned myocardium after thrombolytic therapy for acute MI.

7. Derivation of the Frantz-Nodvik Equation for Diode-Side-Pumped Zigzag Slab Laser Amplifiers With Gaussian Laser Mode and Pump Beam Shapes.

Author

Abstract

The theory for Gaussian beam pulse propagation in a zigzag slab amplifier with a Gaussian pump distribution is detailed. Provisions are made for amplification of an input signal with an elliptical Gaussian spatial mode by modifying the time-dependent photon transport equations as described by Eggleston Frantz, and Injeyan. A comparison is made with experimental results of a diode-side-pumped zigzag slab amplifier element amplifying a near-Gaussian beam. [ABSTRACT FROM PUBLISHER]

12. A Breakthrough for Aortic Valve Stenosis.

Author

Kereiakes, Dean J., Sarembock, Ian J., Mazur, Wojciech, Clarke, Gregory B., Ivey, Tom D., and Answini, Geoffery A.

Subjects

Abstract

The article discusses medical breakthrough on non-surgical treatment for aortic valve stenosis (AS). It states that PARTNER clinical trials were conducted to provide non-surgical option for patients with heart valve problems aside from open-heart surgery using Edwards SAPIEN Valve. It mentions that 358 patients undergo with the trials wherein they were given transcatheter aortic valve implantation (TAVI) with Edwards SAPIEN valve and standard balloon aortic valvuloplasty (BAV) therapy.
