OBJECTIVE Sequential internal thoracic artery (ITA) grafting allows a more complete arterial revascularization of the myocardium. We wanted to verify whether the excellent clinical and angiographic short term results reported by us before where maintained over 10 years and more. METHODS the first consecutive 500 patients having received at least one(More)
OBJECTIVES This study was designed to determine whether acetylcysteine could provide a protective effect on renal function in a population of patients with normal renal function or mild to moderate chronic renal failure, usually referred for a coronary procedure. BACKGROUND Contrast-induced nephropathy is a well-recognized complication of coronary(More)
OBJECTIVES The purpose of this study was to define the pre-operative angiographic variables that could influence graft patency and flow pattern. BACKGROUND Saphenous vein grafts (SVG) and pedicled right gastroepiploic artery (RGEA) grafts are routinely used to revascularize the right coronary artery (RCA). Little is known about the predictive value of(More)
OBJECTIVES This study was performed to assess whether angiography six months after coronary balloon angioplasty or stent implantation has an influence on clinical management and one-year outcome. BACKGROUND The Benestent II study randomized 827 patients to balloon angioplasty or stent implantation. A subrandomization was undertaken allocating patients to(More)
BACKGROUND Although the internal thoracic artery was proven superior to saphenous vein graft in long-term patency, it is thought to be a more resistive conduit than the vein graft. Moreover, patency studies comparing both left and right internal thoracic arteries have provided results favoring the former. Fractional flow reserve is an established functional(More)
Pulmonary arterial wedge pressure (PAWP) is an important marker of cardiac function. Regrettably, it requires catheterization, which can occasionally result in serious complications. A noninvasive method of estimating PAWP would thus be helpful. Recent studies have indicated that the Doppler transmitral flow velocity pattern was strongly dependent on(More)
BACKGROUND In vitro studies have shown that the vasomotor response of internal mammary artery to vasoactive agents differs from that of saphenous vein. METHODS AND RESULTS To assess whether the response in vivo to methylergometrine and to nitrates differs in saphenous vein grafts, internal mammary artery grafts, and coronary arteries, 25 patients were(More)
The purpose of this study was to examine the time course of the changes in left ventricular inotropic state after intravenous pimobendan administration. In conscious dogs, cumulative doses of 1 and 2.5 mg of pimobendan significantly increased heart rate and the isovolumic indices of inotropic state and relaxation. The maximal effect, however, required 2 h(More)
OBJECTIVE Recently we reviewed the 10-year clinical and angiographic outcomes of sequential internal thoracic artery grafting. Most of the patients also received complementary saphenous grafts, and their overall long-term patency rates were surprisingly high. Therefore, we decided to analyze these results in more detail. METHODS The first consecutive 500(More)
PURPOSE OF REVIEW Competition flow is a common finding in arterial grafting. This phenomenon can lead to graft occlusion. RECENT FINDINGS Internal thoracic arteries are the best equipped arterial conduit to withstand the competition flow thanks to their endothelial function. Radial as well as right gastroepiploic arteries support much less flow(More)
