Early experience with low speed rotational angioplasty.

Early experience with low speed rotational angioplasty.

OBJECTIVE Preliminary assessment of the efficacy and safety of the low speed rotational angioplasty catheter system (ROTACS). DESIGN Open prospective trial. SETTING Department of cardiology in a teaching hospital. PATIENTS Eleven patients (10 with chronic stable angina and one with acute coronary occlusion after conventional angioplasty) in whom a coronary angiogram showed occlusion or cr...

Commissioning and early experience with a new generation low-energy linear accelerator in zahedan

Introduction: Since commissioning beam data are treated as a reference and ultimately used by treatment planning systems, it is vitally important that the collected data are of the highest quality to avoid dosimetric and patient treatment errors that may subsequently lead to a poor radiation outcome. Beam data commissioning should be performed with appropriate knowledge and pr...

Ten-year experience with early angioplasty in 759 patients with acute myocardial infarction.

OBJECTIVES How effective and safe is rescue percutaneous transluminal coronary angioplasty [PTCA] compared with primary PTCA, and is it cost effective? BACKGROUND In acute myocardial infarction (AMI), primary PTCA has been shown to be beneficial in terms of clinical outcome. In contrast, the value of rescue PTCA has not been established. METHODS In a retrospective analysis, we compared the ...

Early experimental and clinical experience with a focal implant for lower extremity post-angioplasty dissection.

OBJECTIVES This study provides preliminary data on the safety and feasibility of the use of a novel focal implant for managing post-percutaneous transluminal balloon angioplasty (post-PTA) dissection. BACKGROUND Post-PTA dissection of the lower extremity arteries is managed with stent placement. This provides an acceptable post-intervention result but has long-term disadvantages, such as in-s...
