introduction: this study aimed to compare the thickness of the mesiobuccal furcal canal walls of first and second maxillary molars. materials and methods: this study was performed on total of 30 first and second extracted molar teeth (15 each). the mesiobuccal roots of each tooth were separated at the cement-enamel junction (cej) level and embedded in acrylic resin. the embedded roots were cut ...

BACKGROUND The role of coronary atherosclerosis (CA+) in ventricular remodeling after aortic valve replacement (AVR) for isolated aortic stenosis (AS) is not well defined. We sought to evaluate the impact of not revascularized moderate coronary atherosclerosis in long-term left ventricular (LV) remodeling after AVR. METHODS We assessed by coronariography the coronary artery disease in 66 pati...

OBJECTIVE Fabry disease (FD) is an X-linked inborn error of glycosphingolipid catabolism caused by deficient lysosomal α-galactosidase A activity. Progressive accumulation of globotriaosylceramide and related glycosphingolipids in vascular endothelial lysosomes of the heart, kidneys and brain is responsible for the main disease manifestations. The aim of our study was to assess short-term and l...

BACKGROUND High blood pressure causes left ventricular hypertrophy, which is a negative prognostic factor among hypertensive patients. AIM To assess left ventricular geometric remodeling patterns in patients with essential hypertension or with hypertension secondary to parenchymal renal disease. MATERIAL AND METHODS We analyzed data from echocardiograms performed in 250 patients with essent...

OBJECTIVES To establish a cost-effective and reproducible procedure for induction of chronic left ventricular aneurysm (LVA) in rabbits. METHODS Acute myocardial infarction (AMI) was induced in 35 rabbits via concomitant ligation of the left anterior descending (LAD) coronary artery and the circumflex (Cx) branch at the middle portion. Development of AMI was confirmed by ST segment elevation ...

Acute right ventricular pressure overload shifts the interventricular septum leftward and decreases systolic shortening of the left ventricular (LV) septal-lateral diameter. These changes should alter regional shortening in the LV minor axis. To test this hypothesis, LV minor axis circumferential segment lengths of the septum and anterior, lateral, and posterior walls were measured during pulmo...

Muttipolar recording techniques have been used to study excitation of the canine interventricular septum. Activity commences in the mid left septal endocardium and slightly later near the right anterior papillary muscle. From these sites depolarization spreads over the endocardial surfaces, probably via the Purkinje tissue, at 1 m./sec. and through the septal thickness at one-third this speed. ...

OBJECTIVES We studied the clinical and genetic features of familial hypertrophic cardiomyopathy (FHC) caused by an Asp175Asn mutation in the alpha-tropomyosin gene in affected subjects from three unrelated families. BACKGROUND Correlation of genotype and phenotype has provided important information in FHC caused by beta-cardiac myosin and cardiac troponin T mutations. Comparable analyses of h...

Most of the human hearts presents a specialized bridge known as Septomarginal trabecula which extends from the right side of the ventricular septum to the base of anterior papillary muscle. For the present study we took 30 human hearts. We studied the thickness of the septomarginal trabecula, the height of its attachment to the ventricular wall by considering the supraventricular crest as the l...
