Right ventricular (RV) volumes were calculated from biplane cineangiocardiograms in 46 patients undergoing diagnostic cardiac catheterization. Validation of methodology was performed by comparison of known and calculated volumes of postmortem RV casts as well as by comparison of cineangiocardiographic RV and left ventricular (LV) stroke volumes of patients without shunts or valvular insufficien...

The relationship of the left atrial border imioveiiicits to underlying pressure and volume changes was investigated in individual human subjects with proved initral insufficiency. Based on thetse observations, criteria for the recognition of hemodynamically significant mitral insufficiency have been revised. Special emphasis is placed on a rapid inward mllovement of the atrial wall during the p...

Two adults with severe pulmonic valvular stenosis and atrial flutter are presented. This arrhythmia is apparently a rare complication of this particular form of congenital heart disease. In both cases surgical correction was achieved with the aid of total body perfusion. At the time of surgery, significant tricuspid insufficiency was discovered in both cases. Although the tricuspid valve was no...

PURPOSE This is the first report describing combined spinal epidural anaesthesia for labour and unexpected Caesarean section in a patient with mitral and aortic stenosis and insufficiency. CLINICAL FEATURES The patient was a 30-yr-old GIPO with a history of rheumatic fever. She had moderate stenosis and insufficiency of the mitral and aortic valves. Combined spinal epidural anaesthesia was us...

The hemodynamic consequences of cardiac arrhythmias depend on various factors, including the ventricular rate and the duration of the abnormal rate, the temporal relationship between atrial and ventricular activity, the sequence of ventricular activation, the functional state of the heart, the irregularity of the cycle length, associated drug therapy, the peripheral vascular vasomotor system, d...
