BACKGROUND In this study we examined right and left ventricular systolic functions in hepatitis B virus (HBV) patients. MATERIAL/METHODS The study included 50 HBsAg-positive patients (mean age; 33±13 years) and 50 other persons (mean age; 28±11 years) as a control group. Transthoracic echocardiography was performed in all the participants. Right and left ventricle systolic parameters were com...
Dear Sir, The report on “Right ventricular outflow tract (RVOT) systolic excursion (SE) and fractional shortening (FS)” is very interesting.[1] Allam et al. raised an interesting question, “Can these echocardiographic parameters be used for the assessment of right ventricular (RV) function?” Clinically, RV function assessment is useful for initial assessment, diagnosis, and follow-up of the pat...
Background. The right ventricle (RV) receives part of its systolic pumping force from the left ventricle through systolic ventricular interaction. The purpose of this study was to determine the effects of dilated cardiomyopathy on left ventricular to right ventricular (LV-to-RV) systolic interaction. Methods and Results. Studies were performed in six normal pigs and in six pigs in which dilated...
BACKGROUND Sudden cardiac death and life-threatening ventricular arrhythmia remain a concern in adult patients with repaired tetralogy of Fallot. Longitudinal left ventricular (LV) function is sensitive in detecting early myocardial damage and may have prognostic implications in this setting. METHODS AND RESULTS We included 413 tetralogy of Fallot patients (age, 36 ± 13 years; QRS duration, 1...
Left ventricular function was assessed by angiographic methods in 40 patients (ages 3-27), 1-12 years following repair of tetralogy of Fallot. Twenty of the 40 patients (group A) had a satisfactory repair with a pulmonary-systemic flow ratio (Qp/Qs) less then or equal to 1.5 and a right ventricular systolic pressure of less than or equal to 60% of the left ventricular value. The other 20 patien...
Background—Sudden cardiac death and life-threatening ventricular arrhythmia remain a concern in adult patients with repaired tetralogy of Fallot. Longitudinal left ventricular (LV) function is sensitive in detecting early myocardial damage and may have prognostic implications in this setting. Methods and Results—We included 413 tetralogy of Fallot patients (age, 36 13 years; QRS duration, 148 2...
