Newly Developed Apical Systolic Musical Murmurs during the Left Heart Catheterization

Correlation of heart sounds and murmurs with pressure during left heart catheterization.

T HE development of a method" 2 to obtain triple equisensitive pressure pulses in the left atrium, left ventricle and aorta in the heart exposed at operation, and to display them together, with the same baseline, made it possible to visualize the mechanical events of the cardiac cycle and to measure their phases with great accuracy. It was apparent that the method lent itself naturally to a stu...

Transseptal Left Heart Catheterization

THE PHYSICIAN who desires to carry out hemodynamic or angiocardiographic studies of the left side of the heart has a large number of technics froim which to choose.1 The ideal method for such investigations should fulfill a number of criteria. First of all, the method must be relatively safe. In order to gain wide acceptaniee it must be technically simple and individuals trained in the standard...

Systolic Murmurs in Children

The general practitioner has to deal almost daily in his work with the problem of systolic murmurs. He finds such murmurs often in apparently healthy children during a routine check and is then confronted by the question whether to consider these murmurs as of no importance, or to investigate further. There exists a wide discrepancy among publications on the incidence of systolic murmurs in chi...

Complete atrioventricular block induced during left heart catheterization.

Complete atrioventricular block (CAVB) during cardiac catheterization is a rare complication. We describe a patient with preexisting complete right bundle branch block who developed CAVB during left-sided cardiac catheterization. CAVB was induced when a left-sided catheter was passed through the aortic valve. We speculate that the patient's His bundle was injured by mechanical compression. Phys...
