Tricuspid insufficiency due to nonpenetrating trauma.

This case of tricuspid insufficiency due to nonpenetrating trauma involved a male patient who had received major chest trauma in an automobile accident, had a nonholosystolic murmur that increased slightly during inspiration on standing, and tranient electrocardiographic findings of right bundle branch block. Unlike findings in previous cases, the right atrial V wave was not dominant and was less than 8 mm Hg. An echocardiogram indicating right ventricular volume overload was an essential diagnostic tool that led to cardiac catheterization and definitive diagnosis.

A technique for performing transesophageal echocardiography safely in patients with Zenker's diverticulum.

Transesophageal echocardiography was indicated for evaluation of mitral valve pathology in a patient with a Zenker's diverticulum. However, transesophageal echocardiography is potentially dangerous and therefore relatively contraindicated in such patients. Our gastroenterologist directly intubated the esophagus with a fiberoptic endoscope and introduced an overtube through which transesophageal echocardiography was performed without incident.

Transesophageal echocardiographic findings in blue toe syndrome exacerbated by anticoagulation.

The role of anticoagulation in the blue toe syndrome is unresolved. We describe the sonographic appearance of atherosclerotic plaques in the thoracic aorta imaged by transesophageal echocardiography in 2 patients with blue toe syndrome who had reembolization while taking therapeutic levels of anticoagulants. The findings of complex atheromas associated with mobile highly echodense linear structures by transesophageal echocardiography may be predictive of reembolization in patients with blue toe syndrome who are taking anticoagulants.

Atrial fibrillation and flutter with left bundle branch block aberration referred as ventricular tachycardia.

Five patients were referred for electrophysiologic evaluation of nonsustained or sustained ventricular tachycardia. In each patient, the clinical rhythm disturbance was reproduced and identified as atrial fibrillation or flutter with left bundle branch block aberrancy. All five patients demonstrated enhanced or accelerated atrioventricular conduction through the normal atrioventricular nodal-His Purkinje pathway. This rapid conduction created an electrophysiologic substrate suitable to the preferential development of this less common form of aberration. Four of five patients responded well (ventricular rate control or reversion to sinus rhythm) to verapamil therapy. Electrocardiographic criteria for differentiating supraventricular tachycardia with aberration from ventricular tachycardia exist. Nevertheless, misdiagnosis of wide complex tachycardia remains common. Electrophysiologic testing plays an important role in correctly identifying these rhythms, assessing long-term prognosis, and choosing effective therapy.

Compression of an anomalous left circumflex coronary artery by a bioprosthetic valve ring.

The most common anomaly of the coronary arteries is the origin of the left circumflex artery from the right sinus of Valsalva or the right coronary artery proper. This anomaly is rarely clinically significant. A patient is reported here who has such an anomaly which did become clinically significant after a bioprosthetic aortic valve replacement. The circumflex artery described here became compressed between the Hancock aortic valvular ring and the mitral valvular apparatus. This case is the first antemortem report of such a compression to be demonstrated angiographically and the first case to be the results of an aortic bioprosthetic ring alone. Special surgical considerations must be made when performing valvular replacements on patients with this coronary artery anomaly.
