Diagnosis and management of traumatic ventricular septal defect.

Four cases of ventricular septal defect secondary to stab wounds of the heart are presented. One of three patients arriving at the Emergency Department in shock and who were resuscitated required an emergency thoracotomy. These patients had immediate repair of their external cardiac wounds in the Operating Room. Cases 1 and 3 developed heart failure and loud systolic murmur postoperatively. Case 4 was treated with chest tube for a left hemothorax and developed heart failure after discharge. In Cases 1, 2, and 3, 2-D echocardiography detected and located a VSD. In Case 3 Doppler measurement showed elevated RV pressure (45 mm Hg) and decreased peak tricuspid to mitral flow ratio (0.36, normal = 0.6). All patients underwent cardiac catheterization. In Case 4 there was associated mitral regurgitation. Cases 1 and 3 had pulmonary to systemic flow ratios greater than 3:1. Cases 1, 3, and 4 underwent operative repair. In Case 1 the VSD was closed with a dacron patch, and in Cases 3 and 4 it was sutured with Teflon pledgets. In Case 4 a puncture wound of the mitral valve annulus was simultaneously repaired. All patients are alive but in Case 1 postoperative 2-D echocardiography demonstrated partial dehiscence of the patch which has not required reoperation and in Case 3 post-repair 2-D echocardiography and Doppler flow studies have shown an intact VSD repair. This series of post-traumatic VSD demonstrates its varying clinical presentation and the diagnostic and followup benefits offered by 2-D echocardiography, especially when combined with Doppler flow measures.(ABSTRACT TRUNCATED AT 250 WORDS)

The uses of two-dimensional Doppler echocardiographic techniques preoperatively and postoperatively in a ventricular septal defect caused by penetrating trauma.

Doppler echocardiography was used to determine the site and size of a ventricular septal defect in a patient with a penetrating wound of the heart. Additional physiological measurements by Doppler study, including pulmonary artery pressure and degree of left-to-right shunting, were helpful in deciding on surgical closure of the defect as the definitive therapy in this patient. Associated intracardiac defects (e.g., mitral or tricuspid regurgitation) can be excluded by Doppler echocardiography.

Effect of yellow-tinted lenses on contrast sensitivity.

The effectiveness of yellow-tinted lenses (Norton Visitor Wrap-Around) on contrast thresholds for achromatic sinusoidal gratings was measured on a large sample of healthy, young adults. These measurements were compared with those obtained through luminance-matched neutral goggles. Contrast sensitivity functions for stationary and drifting (2 cycles per second) gratings were measured on two groups of subjects. The results of both experiments show that those subjects demonstrating a subjective preference preferred the yellow tint to the neutral lenses by 2:1. Despite the subjective impression, however, contrast thresholds obtained with the yellow and neutral lenses were not statistically different for either the stationary or drifting gratings.

Low electrocardiographic voltage in pericardial effusion.

Although low ECG voltage has been associated with pericardial effusion, its diagnostic usefulness in such patients is unclear. When we examined the relationship between the volume of pericardial effusion and low voltage in 28 patients who underwent pericardial drainage, 14 patients exhibited low voltage (sum of limb lead QRS amplitudes of 30 mm or less). In eight patients, the QRS amplitude was 5 mm or less in each of the standard leads (absolute low voltage). There was no significant correlation between the volume of the effusion and the QRS amplitude (r = -0.30). This correlation did not improve (r = -0.37) when patients with left ventricular hypertrophy were excluded. Following pericardial drainage, the QRS amplitude increased in 21 of 24 patients and decreased in three. Low voltage persisted in nine patients; the pericardium was thickened in seven of the nine. Analysis of the sensitivity and specificity revealed acceptable sensitivity only with large effusions and no left ventricular hypertrophy. Absolute low voltage appeared to be specific in the diagnosis of moderate and large effusions among patients with pericardial effusion selected for this study.
