TL;DR: In this article, the authors examined the relationship among viability assessment by dobutamine echocardiography (DE), positron emission tomography (PET) and thallium-201 single-photon emission computed tomography(Tl-SPECT) to the degree of fibrosis.
Journal ArticleDOI
Bloody pericardial effusion in patients with cardiac tamponade: is the cause cancerous, tuberculous, or iatrogenic in the 1990s?
TL;DR: The most common cause of bloody pericardial effusion was iatrogenic disease (31%), namely, secondary to invasive cardiac procedures as mentioned in this paper, which may reflect a low incidence of cardiac tuberculosis in community hospitals in the United States.
Journal ArticleDOI
Limitations of postmortem assessment of human coronary artery size and luminal narrowing: Differential effects of tissue fixation and processing on vessels with different degrees of atherosclerosis
TL;DR: Using planimetric techniques, the dimensional changes that occurred with fixation and processing were quantitated in 61 coronary artery segments with minimal or moderate to severe atherosclerosis obtained from 12 patients studied at autopsy.
Journal ArticleDOI

Huai Luo,Huai Luo,Wolfgang Steffen,Wolfgang Steffen,Bojan Cercek,Bojan Cercek,Siva Arunasalam,Siva Arunasalam,Gerald Maurer,Gerald Maurer,Robert J. Siegel,Robert J. Siegel +11 more
TL;DR: In this paper, the efficacy of external ultrasound to enhance in vitro thrombolysis with urokinase or streptokinase was evaluated and it was shown that the combination of ultrasound (2.2 W/cm2, 30 min) and Urokinases or Streptokinases (50, 250, and 2000 mu/ml) significantly increased the lysis rate.
Patent
Stent with sustained drug delivery
TL;DR: A mechanical support or stent containing pharmaceutical agents can be placed in the wall of a blood vessel where it releases pharmaceutical agents to prevent arterial thromboses, platelet aggregation and/or excessive endothelial cell proliferation at the placement site as discussed by the authors.
