We report the natural history, the clinical, radiological, echocardiographic and hemodynamic pattern of a living sixty-three year old man with tetralogy of Fallot and cyanosis since birth. We discuss the possible circulatory adaptations which allowed exceptional survival up to the seventh decade: it is the sixth case reported in the literature.

STUDY OBJECTIVE: The objective of this study was to examine the utility of the transesophageal echo-Doppler device in evaluating hemodynamic changes during laparoscopic cholecystectomy. DESIGN: This was a prospective, controlled, observational open study. SETTING: The study took place in a university hospital. PATIENTS: Twenty patients with ASA physical statuses II and III undergoing laparoscopic cholecystectomy were enrolled into the study. INTERVENTIONS AND MEASUREMENTS: A standardized general anesthetic and surgical technique was used for all patients.

PURPOSE: It has been reported that mental stress is an independent risk factor for cardiovascular events and impairs coronary circulation. Lavender aromatherapy, one of the most popular complementary treatments, is recognized as a beneficial mental relaxation therapy. However, no study has examined the effect of this therapy on coronary circulation. We aimed to assess the effect of lavender aromatherapy on coronary circulation by measuring coronary flow velocity reserve (CFVR) with noninvasive transthoracic Doppler echocardiography (TTDE).

Glucose-mediated oxidative stress and the upregulation of cyclooxygenase (COX)-2 pathway activity have been implicated in the pathogenesis of several vascular complications of diabetes including diabetic neuropathy. However, in nondiabetic subjects, the cardiovascular safety of selective COX-2 inhibition is controversial. The aim of this study was to explore the links between hyperglycemia, oxidative stress, activation of the COX-2 pathway, cardiac sympathetic integrity, and the development of left ventricular (LV) dysfunction in experimental diabetes.

Our objective was to determine if the presence of metabolic complications (MC) conveyed an additional risk for left ventricular (LV) dysfunction in people with HIV. HIV⁺ and HIV⁻ men and women were categorized into four groups: (1) HIV⁺ with MC (43±7 years, n=64), (2) HIV⁺ without MC (42±7 years, n=59), (3) HIV⁻ with MC (44±8 years, n=37), or (4) HIV⁻ controls without MC (42±8 years, n=41). All participants underwent two-dimensional (2-D), Doppler, and tissue Doppler echocardiography. Overall, the prevalence of systolic dysfunction (15 vs. 4%, p=0.02) and LV hypertrophy (9 vs.

Our institution is in development of a low frequency, non-invasive Diastolic Timed Vibrator (DTV) for use in emergency treatment of ST Elevation Myocardial Infarction (STEMI). It is preferable to avoid vibration emissions during the IsoVolumetric Contraction Period (IVCP) and at least the majority of mechanical systole thereafter, as systolic vibration may cause a negative inotropic effect in the ischemic heart.

OBJECTIVES: We determined whether caloric restriction (CR) has cardiac-specific effects that attenuate the established aging-associated impairments in diastolic function (DF). BACKGROUND: Caloric restriction retards the aging process in small mammals; however, no information is available on the effects of long-term CR on human aging. In healthy individuals, Doppler echocardiography has established the pattern of aging-associated DF impairment, whereas little change is observed in systolic function (SF).

Little is known about the effects of weight loss on diastolic function. Furthermore, it is not known whether both caloric restriction (CR)- and exercise (Ex)-induced weight loss have salutary effects on diastolic function. Therefore, we assessed the effects of yearlong CR (n = 12) and Ex (n = 13) interventions, which induced approximately 12% weight loss, on diastolic function in healthy, nonobese (body mass index = 23.5-29.9 kg/m2) men and women aged 50 to 60 yr.

OBJECTIVES: The purpose of this study was to assess the effects of qili qiangxin capsules in patients with chronic heart failure (CHF). BACKGROUND: Qili qiangxin capsules are a traditional Chinese medicine that has been approved in China for the treatment of CHF, but the evidence supporting its efficacy remains unclear. METHODS: A total of 512 patients with CHF were enrolled and randomly assigned to receive the placebo or qili qiangxin capsules in addition to their standard medications for the treatment of CHF.
