Abstract:

The introduction of the arterial switch operation has improved the surgical outcome of transposition of the great arteries. However, coronary anomalies such as intramural coronary arteries, single coronary artery, or coronary arteries originating from a single arterial sinus have been reported as independent risk factors for early mortality and late morbidity after an arterial switch operation. We performed an arterial switch operation using a unique technique for translocation of the coronary arteries originating from a single left-side arterial sinus, to prevent coronary artery distortion an

Abstract:

Aortic stiffness, a cardiovascular risk factor and a marker of arterial aging, is assessed by pulse wave velocity (PWV) over this arterial segment. The interaction between the stiffness of various arterial segments is important in understanding the behavior of pressure and flow waves along the arterial tree. However, PWV assessment has been limited to large elastic vessels (aorta) or medium-sized arteries (i.e., brachial artery). In this paper, we provide a novel and noninvasive method of assessing the regional stiffness of small conduit arteries using the same piezoelectric sensors used for d

SummaryThe arterial supply to the lungs in cases with tetralogy of Fallot with pulmonary atresia or critical pulmonary stenosis is mostly via the arterial duct or else by collateral arteries arising directly or indirectly from the aorta.

The precise supply varied from case to case but, overall, nearly two-thirds of the pulmonary segments were connected to the central pulmonary arteries.

The large elastic arteries fulfill an important role in buffering the cyclical changes in blood pressure, which result from intermittent ventricular ejection.

Indeed, arterial stiffness is now recognized as an important, independent determinant of cardiovascular disease risk.

Abstract:

Arterial smooth muscle constriction in response to pressure, i.e., myogenic tone, may involve calcium-dependent and calcium-sensitization mechanisms. Calcium sensitization in vascular smooth muscle is regulated by kinases such as PKC and Rho kinase, and activity of these kinases is known to be altered in cardiovascular disorders. In the present study, we evaluated the relative contribution of PKC and Rho kinase to myogenic tone in cerebral arteries in hypertension. Myogenic tone and arterial wall calcium in Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR) were measured simulta

Abstract:

Exercise training produces enhanced nitric oxide (NO)-dependent, endothelium-mediated vasodilator responses of porcine coronary arterioles but not conduit coronary arteries. The purpose of this study was to test the hypothesis that exercise training increases the amount of endothelial NO synthase (eNOS) in the coronary arterial microcirculation but not in the conduit coronary arteries. Miniature swine were either exercise trained or remained sedentary for 16–20 wk. Exercise-trained pigs exhibited increased skeletal muscle oxidative capacity, exercise tolerance, and heart weight-to-body weight

Organ cultures of arteries have been used to study growth responses, proliferation, and contractility. However, the function of specific-ion channels in cultured arteries has not been investigated.

Segments from rabbit mesenteric arteries were cultured in for 2-7 days. To explore the properties of KATP channels, the effects of KATP-channel modulators and other vasoactive substances on isometric force,
