An 82-year-old woman undergoing percutaneous transluminal coronary angioplasty experienced perforation of the terminal portion of the left anterior descending coronary artery caused by guidewire trauma. The coronary artery perforation was successfully closed using a vascular occlusion system consisting of individual thrombogenic coils delivered to the site.(More)
A novel skin dose monitor was used to measure radiation incident on maximal X-ray exposed skin during 135 diagnostic and 65 interventional coronary procedures. For the diagnostic studies (n = 135), mean skin dose was 180 +/- 64 mGy; for PTCA (n = 35), it was 1021 +/- 674 mGy, single stents (n = 25) 1529 +/- 601 mGy, and multiple stents with rotational(More)
Fast pulsed magnets with ferrite yokes are used in CERN's SPS accelerator for beam injection, extraction and excitation for tune measurements. The impedance of the ferrite structures can provoke significant beam induced heating, especially for beams with high peak currents as for LHC operation, even beyond the Curie temperature. The expected heating in the(More)
Advances in the understanding of the role of vulnerable plaque coupled with novel diagnostic and therapeutic approaches create a unique opportunity for cardiovascular events prevention due to rupture of vulnerable plaques. Currently, non-invasive methods do not have enough resolution to identify vulnerable plaques, on the other hand, some invasive methods(More)
BACKGROUND Before the "era" of optimal stent deployment, very few data concerning multiple stents in a single coronary artery showed restenosis rates up to 60%. OBJECTIVE To evaluate the 6-month outcome of patients receiving multiple Palmaz-Schatz stents (> or =2 stents) in a single coronary artery compared to those receiving single stents. METHODS(More)
The mortality rate for cardiogenic shock has decreased over the past decade. These improvements are presumed to reflect increased use of intraaortic ballon counterpulsation and coronary reperfusion strategies which, by restoring patency to the infarct-related artery, can limit infarct size. Despite these therapeutic measures, mortality rates remain(More)
