[Results of surgical treatment of calcified aortic valve stenosis: report of a series of 4,129 interventions].

Aortic stenosis (AS) is the most common lesion currently encountered among valvular heart disease, particularly in elderly people. Severe functional impairment and risk of sudden death explain that surgical treatment is largely accepted. We report a retrospective analysis of institutional experience with aortic valve replacement (AVR) for AS from 1971-1997 in 4,129 patients.

Dynamic analysis of the QT interval in long QT1 syndrome patients with a normal phenotype.

Aims: In families with the long QT syndrome penetrance may be low: up to 70% of gene carriers may have a normal QTc interval. These patients require therapy, similar to that in those with longer QTc intervals, but identifying them, using molecular analysis, is difficult to apply on a large scale. A large French family affected by the long QT1 syndrome was followed-up over a 25-year period.

CARDIOMEDIA: a communicable multimedia medical record on Intranet and digital optical memory card.

As part of French health reform, French physicians were computerised by the end of 1998. A specific Intranet network will be used to communicate medical data between the health professionals. The objectives of the CARDIOMEDIA project were to develop and evaluate the feasibility of a coronary multimedia data record stored on an optical card and communicable on Intranet within the hospital.

Clinical and angiographic results of stenting for long coronary arterial atherosclerotic lesions.

A prospective registry of 187 patients who underwent percutaneous coronary angioplasty with attempted long NIR stent delivery was performed. A successful stent delivery was achieved in 93% of cases with a low rate of major cardiovascular events, and 6-month follow-up showed low rates of clinical events, new revascularization procedures, and angiographic restenosis.

Aneurysms and pseudoaneurysms of saphenous vein coronary artery bypass grafts.

Aneurysms of saphenous vein grafts to coronary arteries are unusual complications of coronary artery bypass graft (CABG) surgery. Three patients (men aged 47, 62, and 68 years) are presented with spontaneous chest pains 10, 21, and 17 years after CABG surgery. In one case, the saphenous vein graft had eroded into the right atrium and had established a fistula between the graft and the right atrium.
