The risk of diagnostic cardiovascular catheterization.

This report details a prospective study of the risk of diagnostic cardiac catheterization performed in a private, community hospital. Over the first 131 months of operation of our laboratory, 745 adult patients underwent diagnostic cardiac catheterization consisting of 2,676 various catheterization procedures. Six patients experienced seven major complications; two of these complications left a permanent deficit. There were no deaths during catheterization and none later which were attributable to it. The risk to the patient of having a major complication associated with a cardiac catheterization in our series was 0.8 per cent. The risk to the patient of having a major complication when a catheterization procedure was performed was 0.3 per cent. The risk of having a complication resulting in a permanent sequela was 0.07 per cent. We conclude that diagnostic cardiac catheterization can be accomplished with little risk to the patient, either of death or of other major complication.

Case report: factors involved in the production of the presystolic murmur in a patient with mitral stenosis and atrial trigeminy. Correlation of echocardiographic, phonocardiographic, and hemodynamic data.

The study of a patient with mitral stenosis and periods of atrial trigeminal rhythm afforded an opportunity to test some factors important in the production of the presystolic murmur. The echocardiogram and phonocardiogram were correlated with hemodynamic data obtained both with the patient at rest and with right atrial and ventricular pacing. The results showed that atrial contraction was a major determinant in the production of the presystolic murmur and seemed to exert an even greater influence than did either the end-diastolic pressure gradient across the mitral valve or the duration of the preceding RR interval. Corollaries from this study may have practical application for the clinician in his bedside physical examination. The data suggested that the production of the presystolic murmur in our patient might have been related to geometrical shifts of intracardiac anatomical structures resulting from changes in the left ventricular end-diastolic distending pressure.

The effect of atrial rhythm on the thoracic impedance cardiogram.

We have observed that the thoracic impedance waveform is altered when there is a change in atrial rhythm. In order to investigate this, we selected for review impedance cardiograms of patients with various atrial rhythms. The study showed that the thoracic impedance waveform displays characteristic deflections that are specifically associated with different atrial rhythms and are analogous to those seen on the electrocardiogram. The finding that the waveform was sensitive even to the small atrial movements discernible during the rhythm of coarse atrial fibrillation was consistent with the possibility that blood flow within the vena cave-right atrial and/or the pulmonary venous-left atrial systems may be important in the genesis of the cardiac thoracic impedance waveform.

Trochanteric fractures treated with the Pugh nail: a study of 270 cases.

We report a series of 270 intertrochanteric fractures of the femur which were treated with the Pugh nail in our department. We used it as a standard treatment of intertrochanteric fractures and lateral fractures of the femoral neck. The Pugh nail method is characterized by a simple technique, a low rate of complications, and early ambulation and weight-bearing, which is important for the mostly aged patients (average age: 81 years). 81% of the patients could be ambulized with weight-bearing within two weeks after operation. 79% of them were able to walk by themselves at discharge from hospital. The rate of complications was 17% without urinary infections. Mortality was 16%. Complications and mortality did not depend on the type of fracture but on the age of the patients and on concomitant diseases.
