Balloon angioplasty is an effective means of treating in-stent restenosis. The long-term results are acceptable particularly for focal restenotic lesions. Further restenosis is more common in patients with early initial recurrence, more proliferative lesions and a poorer angiographic result from repeat angioplasty.

Objective: To report on the results of using a lateral thyrotomy approach on the paraglottic space to gain greater access for laryngocele resection under direct vision. Study Design: A 26-year prospective and retrospective study. The study was conducted on 10 adult patients (5 men and 5 women) who had laryngocele of varying size on the paraglottic space. Six of the patients had internal laryngocele and four had exteriorized laryngocele. Five laryngoceles were leftsided, three were right-sided, and two were bilateral. Methods: A V-shaped, full-thickness thyroid lamina resection with the triangle base at the superior border and the apex at a point midway of the thyroid lamina vertical extent was performed. Results: A V-shaped lateral thyrotomy made exposure to the paraglottic space possible for direct submucosal laryngocele dissection. This approach has presented no complications to date. Postoperative minor edema or hematoma was found in the aryepiglottic and ventricular folds, but this disappeared within a few days. There was no recurrence; the minimum follow-up was 1 year. Conclusion: The triangular lateral thyrotomy approach provided access to the paraglottic space and superb visibility for resection of laryngocele of any size under direct vision, thus avoiding recurrence, morbidity, and complications.

Coronary stenting can be performed safely in high-risk individuals with acceptable intermediate-term outcome. It may be feasible to broaden the application of this technique in selected patients needing revascularization for left main coronary disease.

The term athlete's heart refers to an increased left ventricular mass. Few studies have assessed the prevalence and normal upper limit of cardiac hypertrophy in highly trained cyclists and this was the aim of this study. A group of 40 professional road cyclists [mean age 26 (SD 3) years] who had participated in European competitions for 3-10 years, were evaluated at the beginning of the 1992-93 season. Evaluation included a clinical history and physical examination, one and two-dimensional echocardiography, 12-lead resting electrocardiogram and a graded exercise test. Determination of the left ventricular mass index (LVMI) was performed using Devereux's formula with correction for the body surface area. Systolic and diastolic blood pressure were measured at rest and at peak exercise. Of the group 23 cyclists (58%) presented a LVMI greater than 130 g.m-2, 21 cyclists presented a diastolic ventricular thickness equal to or greater than 13 mm, with a superior limit of 19 mm; 3 cyclists presented asymmetrical septum hypertrophy; and the relationship between posterior wall and left ventricular diastolic radius was equal to or greater than 0.45 in 14 cases (35%). Electrocardiographic abnormalities of ST-T segment were seen in only 1 subject. No correlation was found between the degree of ventricular hypertrophy and arterial blood pressure. We concluded that these professional cyclists showed a high prevalence of cardiac hypertrophy (58%). The distribution of this hypertrophy was concentric in 20/33 and asymmetric in 3/23 of the subjects with left ventricular hypertrophy. The electrocardiograms were normal in 98% of the subjects.
