This study aims to demonstrate the use of surgical ostioplasty left main coronary artery as an alternative technique conventional bypass grafting for treatment stem-isolated ostial stenosis. From 2002 2021, five patients—three women (60%) and two men (40%)—presented with a history angina pectoris were diagnosed isolated stenosis ostia associated normal distal arteries. Pre-operative cardiac cat...

As shown in 2065 women aged 18 to 45 Years from seven countries of Central and North America, the population frequency of normal medullary stenosis ranges from under 2% to nearly 7%. In this condition, endosteal apposition may begin in infancy and continue through the fourth decade with a compensatory reduction in the rate of subperiosteal apposition, leading t o an approximately normal cortica...

Introduction Congenital pulmonary vein stenosis (CPVS) is one of cardiac anomalies producing generalized pulmonary venous hypertension such as mitral stenosis, a supravalvar mitral ring, mitral regurgitation, and total anomalous pulmonary venous connection. The prognosis is poor with the development of progressive pulmonary venous congestion followed by pulmonary arterial hypertension and event...

BACKGROUND Power Doppler (PD) has improved diagnostic capabilities of vascular sonography, mainly because it is independent from the angle of insonation. We evaluated this technique in a prospective comparison with conventional imaging, consisting in Duplex and Color Doppler, for the evaluation of Renal Artery (RA) stenosis. METHODS Sensitivity, specificity and predictive values of PD and con...

In order to establish a new echocardiographic index of the severity of mitral stenosis, left ventricular echocardiograms were digitised using manual tracing and a computer. The instantaneous left ventricular dimension was measured in 15 patients with mitral stenosis. The peak rate of change of left ventricular dimension (peak dD/dt) and the normalised peak rate (peak dD/dt/D) during early diast...

Hypertrophy is considered one of the major mechanisms of the myocardium for adapting to hemodynamic overload. More muscle mass provides more contractile elements for generating the extra work required by the overload. In pressure overload of aortic valve stenosis, concentric left ventricular hypertrophy (LVH) normalizes wall stress, a key determinant of ejection performance.1 Afterload is often...

Measurements of the thickness of the septum were made in 26 cardiac specimens and in 13 patients. There were 10 normal specimens, five with aortic stenosis, two with asymmetric septal hypertrophy, four with hypertensive cardiovascular disease, and five with idiopathic cardiomyopathy. Patient measurements were obtained by visualizing the septum during simultaneous left and right ventriculography...

Subglottic stenosis is rarely idiopathic. In this case report, a 40-year-old female patient presented with subglottic stenosis with an unidentified etiology along with bilateral bronchial stenosis. Hoarseness arose in the last 4 years in this patient, who was undergoing treatment because of asthma for 13 years. Her physical examination revealed the presence of bilateral rhonci. Her tomography a...

OBJECTIVE To evaluate the hydrodynamic changes occurring in cerebrospinal fluid (CSF) flow in cervical spinal stenosis using the spatial modulation of magnetization (SPAMM) technique. MATERIALS AND METHODS Using the SPAMM technique, 44 patients with cervical spinal stenosis and ten healthy volunteers were investigated. The degree of cervical spinal stenosis was rated as low-, intermediate-, o...

Ninety-six patients with greater than or equal to 50% unilateral vertebral artery (VA) stenosis were followed up for an average of 4.6 years. In 89 patients (93%) at least one VA origin was involved, while the intracranial VA was affected in 3 patients (3%). Seventy-four patients (77%) had greater than or equal to 50% stenosis of at least one internal carotid artery, of whom 52 underwent caroti...
