Usually the left ventricular cavity is adequately visualized with 30 to 50 mL of contrast. Indications: Assessment of left ventricular function including left ventricular ejection fraction, wall motion abnormalities, ventricular size and mass The primary outcome was the concomitant use of left ventriculography during coronary angiography. These tests should be: 1. This view allows the visualization of the anterior, apical, inferior, and high lateral walls. It is done to diagnose or treat certain heart problems. Left ventriculography has gone from the status of prima ballerina to understudy in the ballet of left ventricular assessment.

Left heart ventricular angiography is a procedure to look at the left-sided heart chambers and the function of the left-sided valves. 1, 2, 3 In this procedure, a catheter is inserted retrograde across the aortic valve via percutaneous arterial access, and contrast dye is injectedtypically 30 to 40 mL over 3 to 4 seconds 4 ( Figure 1 ). Performed selectively and avoided when an adequate alternative left ventricular imaging study has been performed. we sought to analyze the frequency that left ventriculography was performed during coronary angiography in patients with and without a recent alternative assessment of left ventricular function.we performed a retrospective analysis of insurance claims data from the aetna health care benefits database including all adults who underwent coronary
Left ventriculography is a routine and accurate method of evaluating left ventricular ejection fraction (EF) at the time of coronary angiography. Given the lack of guidelines for left ventriculography, it is difficult to state that use in any particular case was inappropriate. Indications Coronary angiography is widely used to evaluate patients with known or suspected CAD. .

Left ventricular (LV) contrast (left ventriculography) gives information on its volume, general and regional contractility, the state of mitral (regurgitation) of the valve, the presence and localization of the septal defect, changes in the shape and configuration of the cavity in aneurysm, ischemia or hypertrophy of the myocardium. The usual settings of the power injector for left ventriculography are 30-50 mL of contrast dye volume at an injection rate of 12-15 mL/second and gradual flow rate rise over 0.5-1.0 second when a 6-Fr pigtail catheter is used. Use of left ventriculography was high in all subgroups, with greatest use in younger patients, those with a diagnosis of coronary disease, and those in the Southern United States. J Nucl Med . 2. Radionuclide left ventriculography with the slant hole collimator.
In obese patients with difficult echocardiographic windows, ventriculography may provide diagnostic information that cannot be obtained from the echocardiogram. Left ventriculography ("the left ventriculogram") has been performed as a means of assessing left ventricular function for almost 50 years. Adult patients greater than 18 years of age referred for radial coronary angiography with left ventriculography for clinical indications at the Loma Linda Heart and Surgical Hospital or the Loma .

Left ventriculography allows assessment of left ventricular systolic function, degree of mitral regurgitation, and the presence/location of wall motion abnormality or ventricular septal defect (Table 5-1). Left Ventriculography and Aortography Mateen Akhtar Frederick A. Heupler Jr. Left ventriculography provides important anatomic and functional information that supplements coronary angiography. Considered when left ventricular function or wall motion is unknown, or when mechanical disruption is suspected and results of the study will help determine therapy. Critics argue that it adds to the cost and risk of cardiac catheterization and may be replaced by noninvasive imaging 1.The use of left ventriculography varies widely across different geographic zones and different hospitals 1, reflecting differences in . Left ventriculography is commonly performed in the right anterior oblique projection. 2013 ACC/AHA . Results: Conclusions: Left ventriculography was performed in most coronary angiography cases and often when an alternative imaging modality had been recently completed. Coronary- and LV-angiography in coronary heart disease are indicated I) to clarify whether or not surgery is required (e.g. As used by AIM, the Guidelines establish objective and evidence-based, where . Coronary- and LV-angiography are contraindicated in 1) generalized stenosing atherosclerosis, 2) acute myocardial infarction, 3) failure from other organ-systems (e.g.
