Interventricular Mechanical Asynchrony in Pulmonary Arterial Hypertension
Methods In 21 PAH patients (mean pulmonary arterial pressure 55 13 mm Hg and electrocardiogram–QRS width 100 16 ms), magnetic resonance imaging myocardial tagging (14 ms temporal resolution) was applied. For the left ventricular (LV) free wall, septum, and right ventricular (RV) free wall, the onset time (Tonset) and peak time (Tpeak) of circumferential shortening were calculated. The RV wall t...
متن کاملInterventricular asynchrony in Chronic Thrombo Embolic Pulmonary Hypertension recovers after pulmonary endarterectomy: role of right ventricular wall stress
Methods Reduction of RV wall stress was accomplished by pulmonary endarterectomy (PEA), which is the surgical removal of thrombo-emboli out of the pulmonary arteries. In 13 consecutive patients with CTEPH, MRI myocardial tagging (29 ms temporal resolution) was applied before and after PEA (fig 1). For the left ventricular (LV) free wall, septum (S) and RV free wall, the time to peak (Tpeak) of ...
متن کاملTHE EFFECTS OF CAPTOPRIL ON PULMONARY AND SYS TEMIC ARTERIAL PRESSURES IN HIGHALTITUDE PULMONARY HYPERTENSION
The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...
متن کاملThe Effect of Interventricular Asynchrony
Eighteen patients with isolated left bundle branch block (LBBB) were compared with 10 normal control subjects. Apexcardiograms, phonocardiograms, electrocardiograms, two-dimensional and dual M-mode echocardiograms, and radionuclide ventriculograms (RNV) were performed. There were no differences in the timing of right ventricular events between LBBB and normal subjects; however, striking delays ...
متن کاملThe Importance of Electrocardiography in Pediatric Patients with Pulmonary Arterial Hypertension in Follow- up
Background: Right Ventricular (RV) hypertrophy is an adaptive response to chronic RV pressure overload in patients with pulmonary hypertension. We investigated the relationships between RV hypertrophy indicators, including electrocardiography, the percentage oxygen saturation (SaO2%), body mass index (BMI), and blood uric acid levels in patients with...
