Retrograde coronary aortic dissection is a rare but dangerous complication of coronary angioplasty. Mostly seen in right coronary artery procedures, especially in chronic total oclussion lesions, and rarely seen in left side procedures. This is a case report of an aortic dissection complicated by coronary angioplasty of the left circumflex artery. Immediate stenting of the left main coronary ar...

OBJECTIVES To determine the relative degree of revascularization obtained with bypass surgery versus angioplasty in a randomized trial of patients with multivessel disease requiring revascularization (Bypass Angioplasty Revascularization Investigation [BARI]), one-year catheterization was performed in 15% of patients. BACKGROUND Complete revascularization has been correlated with improved out...

Objectives. We hypothesized that atherectomy would be superior to balloon angioplasty for ostial and nonostial left anterior descending coronary artery lesions. Background. Balloon angioplasty of ostial coronary artery lesions has been associated with a lower procedural success rate and a higher rate of complications and of restenosis than angioplasty of nonostial stenoses. Directional coronary...

Inappropriate percutaneous transluminal coronary angioplasty of the anterior descending artery was avoided in a 52-year-old woman when the intracoronary administration of glyceryl trinitrate immediately before the angioplasty disclosed the organic component of the supposedly fixed, critical (80%) stenosis to be less than 50% of the lumen diameter. The spastic component of the stenosis had not b...

A detailed study of radiation doses received by 168 patients who underwent coronary angiography (CAG) and 102 patients who underwent percutaneous transluminal coronary angioplasty (PTCA) in two Greek hospitals is presented. Radiation dose was measured in terms of dose-area product (DAP). The contribution of fluoroscopy and cineradiography to the total DAP was examined separately for each radiol...

There is no current guideline for percutaneous coronary angioplasty in stenotic ectatic coronary arteries because of the heterogeneity of the coronary artery morphology. We report two successful angioplasty cases in coronary artery ectasia with different clinical scenarios. One case showed atherosclerotic stenosis in the ectatic portion of the right coronary artery that was aggravated after a c...

BACKGROUND Percutaneous balloon angioplasty has become a well-established and routine procedure for coronary revascularization of haemodialysis patients with coronary artery disease. However, the incidence of restenosis after balloon angioplasty is significantly higher in haemodialysis patients than in the general population. We performed a retrospective study comparing balloon angioplasty with...

Harling et al. [1] had a motivating article about surgical patch angioplasty of the left main coronary artery (LMCA). They gave a comprehensive and up-dated review of the issue including the different surgical methods and the variety of patch materials used so far: pericardium, saphenous vein, internal thoracic artery and pulmonary artery. However, they also stated that the optimal patch graft ...

R estenosis is a significant limitation of catheter-based treatment of coronary artery disease. Early in the development of balloon angioplasty, restenosis was quite common, occurring in 30% to 40% of patients (1). Following successful angioplasty, patients who had become symptomfree developed the same symptoms they had experienced prior to the intervention. Repeat angiography demonstrated a re...
