Left radial approach for coronary angiography: results of a prospective study.

Although radial approach has been shown to be feasible for coronary angiography, angioplasty, and even stent placement, there have been no prospective evaluations of ease and safety of left radial approach for coronary angiogram. We examined procedural duration and success as well as complications in 415 consecutive patients. Radial artery occlusion was assessed immediately post-procedure and at 2 month follow-up using echo-Doppler measurements.

Rotational atherectomy with adjunctive balloon angioplasty versus conventional percutaneous transluminal coronary angioplasty in type B2 lesions: results of a randomized study.

A randomized pilot study was performed comparing conventional balloon angioplasty (percutaneous transluminal coronary angioplasty [PTCA] group) and rotational atherectomy (RA) with a medium size burr (50% to 70% burr/artery ratio) with systematic adjunctive balloon angioplasty (RA group) in type B2 stenosis. A total of 64 patients were included. Primary success was 93.

[Isolated stenosing calcified lesions of the aorta].

Two cases of isolated calcified lesions of the aorta are reported. The first observation is that of a 25 years old man suffering from mild intermittent claudication predominant in the left leg. Radiological examination showed a calcified isolated lesion of the infra renal abdominal aorta.

[Ostial stenosis of the renal arteries: treatment by angioplasty].

In a series of 50 patients (22 females, 28 males); 52 ostial renal artery stenoses were treated by transluminal balloon angioplasty. The mean age of patients was 66 years (range 36-81); mean arterial pressures were 181 mmHg for the systolic pressure and 87 mmHg for the diastolic pressure. The mean level of serum creatinine was 179 mumol/l +/- 128.

[Evaluation of a new commercial kit for emergency determination of serum myoglobin].

The usefulness of a nephelometric-based serum myoglobin assay kit in the early diagnosis of acute myocardial infarction was assessed in 92 consecutive patients admitted within 24 hours of the onset of spontaneous chest pain lasting > or = 20 minutes. The discharge diagnosis was acute myocardial infarction in 37 patients (40.2%), myocardial infarction lasting > or = 6 hours in 10, and no myocardial infarction in 45 (48.
