-type natriuretic peptides (BNP and N-terminal [NT]roBNP) have been shown to be extremely helpful in the iagnosis, prognosis, and monitoring of therapy of patients ith heart failure (HF) (1). These neurohormones are preominately secreted from the left and the right cardiac ventricle n response to cardiac stress. The BNPs can be seen as uantitative markers of HF summarizing the extent of systoli...

BACKGROUND The outcomes of patients treated with implantable defibrillators were compared between patients with left ventricular ejection fraction greater than or equal to 30% and less than 30%. METHODS AND RESULTS Of 68 consecutive patients treated with implantable defibrillators, 40 patients (group 1) had left ventricular ejection fraction greater than or equal to 30%, and 28 patients (grou...

The present case reports on a patient presenting the cardiac form of Chagas disease, with left ventricular dysfunction and second-degree atrioventricular block Mobitz type II, associated with several syncope episodes. The patient underwent a double-chamber definitive artificial pacemaker implant. One year after the implant, the displacement of the atrial electrode was diagnosed and the patient ...

Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...

Surgical repair of Tetralogy of Fallot (TOF) is highly successful but may be complicated in adulthood by arrhythmias, sudden death, and right ventricular or biventricular dysfunction. To better understand the molecular and cellular mechanisms of these delayed cardiac events, a chronic animal model of postoperative TOF was studied using microarrays to perform cardiac transcriptomic studies. The ...

Increased left ventricular dilation and reduced systolic function are consistently associated with a poor prognosis worse clinical outcomes. In this review, we discuss the pathophysiological mechanisms, use of cardiac imaging, implications adverse remodeling. Unique situations evidence spontaneous recovery their underlying mechanisms evaluated. A comprehensive appreciation current surrounding a...

Dialysis can be used in severe cases, but may not be well tolerated. In such patients, peritoneal drainage could be an alternative option for fluid removal. We report the case of a newborn with a truncus arteriosus who developed postoperatively a complicated clinical course with right ventricular dysfunction, prerenal condition as well as fluid overload despite diuretic therapy. Dialysis was in...

this paper presents the case of a 35 year-old woman with symptoms of heart failure from the last month. a physical examination at admission showed paleness, dyspnea, peripheral edema and fatigue. in a two-dimensional echocardiography and transesophageal echocardiography, normal thickness but severe left and right ventricular dysfunction with severe pericardial effusion and thickened pericardium...

AIMS Right ventricular dysfunction is a well recognized adverse prognostic factor in patients undergoing surgical aortic valve replacement. The prognostic significance of right ventricular dysfunction in the context of transcatheter aortic valve implantation (TAVI) has not been established. We evaluated the relationship between preprocedural right ventricular impairment and the outcome of TAVI....

The patient had a clinical history of stable coronary artery disease, hypertension, hypercholesterolemia, and chronic (non-dialytic) renal insufficiency with baseline creatinine clearance of 20 mL/min. His surgical history included cardiac revascularization at the age of 45 years, and left internal carotid angioplasty and stenting after a stroke episode in 2004, which left no persistent deficit...
