Infective endocarditis caused by in a patient with bicuspid aortic valve: A case report.

is a gram-positive coccus, and commensal of the upper respiratory tract and oral mucosa. In rare cases, it has been identified as an opportunistic pathogen in the development of endocarditis. Here, we describe a case of endocarditis in a patient with bicuspid aortic valve.

Ventricular Septal Defect and Right-Sided Infective Endocarditis.

Right-sided infective endocarditis (IE), which represents a small but not negligible percentage of IE cases, can be observed in patients with congenital heart diseases. We discuss the case of a young woman with unrepaired perimembranous ventricular septal defect and repeated episodes of right ventricle and tricuspid valve IE with septic embolism.

Never too Grown-Up for a Congenital Heart Disease: Diagnosis of Transitional Atrioventricular Canal in a 50-Year-Old Male.

Transitional atrioventricular (AV) septal defects are uncommon congenital heart defects, and diagnosis is usually made in childhood. We present the case of intermediate AV canal diagnosed in a man referring to cardiological examination for the first time in his life at the age of fifty for exertional dyspnea. The absence of medical examination or execution of electrocardiogram or echocardiogram in childhood or in youth and the very late appearance of symptoms lead to a late diagnosis of this congenital heart disease (CHD).

Surgical management of a free-floating thrombus in the ascending aorta.

The ascending aorta is an uncommon site of noninfective thrombus. We describe the case of a 63-year-old woman who was admitted to our department with acute myocardial infarction. Coronary angiography showed occlusion of a small diagonal vessel, likely related to a distal embolization event.

Effects of barnidipine on blood pressure and left ventricular diastolic function in patients with hypertension and metabolic syndrome: A 12-week, open-label noncomparison study.

Background: Barnidipine is one of a new generation of dihydropyridine calcium-channel blockers. Despite evidence of favorable effects on blood pressure (BP) and insulin sensitivity, this drug has rarely been tested in hypertensive patients with metabolic syndrome (MS).

Objective: The aim of this study was to evaluate the effects of barnidipine on BP and left ventricular (LV) diastolic function in patients with hypertension and MS.

Is the definition of daytime and nighttime blood pressure prognostically relevant?

Objectives: Although the prognostic value of the day-night blood pressure (BP) changes is well established, the most appropriate method for definition of daytime and nighttime BP is still undefined. In a recent guidelines document of the European Society of Hypertension, there is no clear position in favor of one definition over other.

Methods: In the setting of the Progetto Ipertensione Umbria Monitoraggio Ambulariale study, we analyzed the prognostic impact of the day-night BP changes by using three widely used different definitions of day and night (large fixed-clock intervals, narrow fixed-clock intervals, diary) in 2934 initially untreated participants with essential hypertension.

The clinical significance of white-coat and masked hypertension.

Objective: Self-measured blood pressure (BP) and 24-hour ambulatory blood pressure (ABP) monitoring are used to define the arbitrary clinical categories of masked hypertension (MH) and white-coat hypertension (WCH). Severity of target organ damage and incidence of major cardiovascular events are greater in patients with MH than in patients whose BP is normal both inside and outside the doctor's office.

Methods: We reviewed studies that addressed the prognostic impact of MH and WCH.

Validation of the A&D wrist-cuff UB-511 (UB-512) device for self-measurement of blood pressure.

Objectives: To determine the accuracy of the A&D UB-511 (UB-512) oscillometric wrist-cuff device for self-measurement of blood pressure, the only difference between the two devices being the size of storage memory.

Methods: Device evaluation was performed according to the modified British Hypertension Society protocol released in 1993. Eighty-five study participants with characteristics outlined in the British Hypertension Society protocol were recruited among those attending our out-patient clinic.

Day-to-day variability of electrocardiographic diagnosis of left ventricular hypertrophy in hypertensive patients. Influence of electrode placement.

Objective: Although electrocardiography (ECG) is recommended in all subjects with hypertension, no information is available on the influence exerted by random changes in the placement of electrodes on the day-to-day variability of ECG criteria for diagnosis of left ventricular hypertrophy (LVH).

Methods: In a multicentre, randomized study, two standard 12-lead ECG were recorded, 24 h apart, from 276 consecutive hypertensive patients (mean age 65 +/- 12 years, 49.6% men).

Regression of left ventricular hypertrophy and prevention of stroke in hypertensive subjects.

Background: Left ventricular hypertrophy (LVH) is a risk marker for stroke and its regression confers protection from stroke. The relationship between serial LVH changes and risk of stroke has never been investigated in a mixed population of hypertensive subjects with and without LVH.

Methods: In this study, 880 initially untreated hypertensive subjects (mean age 48 years, office blood pressure (BP) 155/98 mm Hg; 24-h BP 137/87 mm Hg) underwent tests including echocardiography and 24-h ambulatory BP monitoring at entry and after a median of 3.

White-coat hypertension in adults.

White-coat hypertension is defined by the coexistence of persistently high office blood pressure (BP) with normal self-measured or ambulatory blood pressure. The prognostic impact of white-coat hypertension is a subject of debate. Cardiovascular morbidity seems to be lower in white-coat hypertension than in ambulatory hypertension, and, according to some but not all studies, is not dissimilar between white-coat hypertension and clinical normotension.

Asymptomatic left ventricular systolic dysfunction in essential hypertension: prevalence, determinants, and prognostic value.

Prevalence, determinants, and prognostic value of asymptomatic left ventricular systolic dysfunction (LVSD) in uncomplicated subjects with essential hypertension are still incompletely known. We studied 2384 initially untreated subjects with hypertension, no previous cardiovascular disease, and no symptoms or physical signs of congestive heart failure (CHF). These subjects were studied at entry and followed for up to 17 years (mean 6.

Effects of acute myocardial ischemia on QT dispersion by dipyridamole stress echocardiography.

Increased dispersion of the QT interval has been observed during pacing or exercise stress testing in patients with coronary artery disease (CAD). It has not been established whether this phenomenon is a consequence of ischemia. Therefore, we sought to evaluate whether dipyridamole-induced myocardial ischemia, as directly detected by echocardiographic monitoring of regional contractile function, would affect QT dispersion.
