Left Axis Deviation in Tricuspid Atresia and Single Ventricle

Left axis deviation in tricuspid atresia and single ventricle; the electrocardiogram in 36 autopsied cases.

Left ventricular function in double inlet left ventricle before the Fontan operation: comparison with tricuspid atresia.

Fourteen patients with double inlet left ventricle and nine patients with tricuspid atresia had biplane left ventricular angiography with simultaneous measurement of left ventricular pressure by micromanometer. Age distribution, haemodynamic function, and previous palliative operation were similar in the two groups. Left ventricular volumes were calculated frame by frame throughout the cardiac ...

Left Axis Deviation

The effects of left axis shift (> -30°) on intraventricular conduction time (IVCT) were studied in 63 subjects in whom electrocardiograms before and after appearance of the left axis shift were available. Subjects with electrocardiographic evidence of left or right ventricular hypertrophy, left or right bundle branch block, myocardial infarction, pre-excitation and those receiving antiarrthythm...

Left Ventricular Function in Tricuspid Atresia

Thirty-one left ventricular (LV) biplane angiograms were performed in 28 patients with tricuspid atresia. Measurements of left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume were obtained by the modified Simpson's rule and systolic ejection fraction (EF) calculated. Left ventricular volumes and ejection fractions were also obtained in 19 control patients with ...
