Cardiac catheterization in dogs

New technique for portal catheterization in dogs.

Interventional cardiac catheterization.

Over the past decade, transcatheter interventions have become increasingly important in the treatment of patients with congenital heart lesions. These procedures may be broadly grouped as dilations (e.g., septostomy, valvuloplasty, angioplasty, and endovascular stenting) or as closures (e.g., vascular embolization and device closure of defects). Balloon valvuloplasty has become the treatment of...

Complications of Cardiac Catheterization

Because all cardiac catheterizations involve the insertion of foreign objects (i.e., cardiac catheters) into the circulatory system, it should not be surprising that a variety of adverse events (complications) can ensue. These complications range from minor problems with no long-term sequelae (e.g., transient bradycardia during coronary contrast injection) to major problems [e.g., cardiac perfo...

Fatality following cardiac catheterization injury.

The widespread use of cardiac catheterization has revealed certain dangers inherent in the procedure when the catheter is advanced beyond the tricuspid valve. Ventricular and other ectopic rhythms are a well recognized risk, but less is known about the effect of damage to the endocardium produced by the catheter in man (Zimdahl, 1951). This paper presents in detail a case that terminated fatall...

Validation Studies at Cardiac Catheterization

In this study, we explored the use of continuous wave Doppler-echocardiography guided by color Doppler flow-mapping as a method for noninvasively calculating the rate of pressure rise (RPR) in the left ventricle. Continuous wave Doppler determination of the velocities in mitral regurgitant jets allows calculation of instantaneous pressure gradients between the left ventricle and the left atrium...
