Study Design

Intervention model single group assignment
Masking open label
Primary purpose diagnostic
stress echocardiograms involving the use of intravenous Optison or Definity contrast agents to improve endocardial definition
dobutamine stress echocardiogram Definity
stress echocardiograms involving the use of intravenous Optison or Definity contrast agents to improve endocardial definition

Primary Outcomes

Provide a higher sensitivity required to adequately assess risks in the pancreas/ kidney transplant evaluation
time frame: I year

Secondary Outcomes

Eliminate the need for costly and invasive additional procedures
time frame: 1 year

Eligibility Criteria

Male or female participants at least 19 years old.

Inclusion Criteria: - Patients who are being evaluated for a kidney and or pancreas transplant and scheduled for a dobutamine stress echocardiogram and a coronary angiogram will be eligible to participate Exclusion Criteria: - Patients with unstable angina at the time of their evaluation, or who have a severe underlying cardiomyopathy or valve disease will be excluded.

Official title The Analysis of Data Collected During Angiography and Dobutamine Stress Contrast Echocardiograms in the Pre-Evaluation of Kidney and Pancreas Transplant Patients
Principal investigator Thomas R Porter, MD
Description Although there is an increasing quantity of data demonstrating the value of stress echo in risk stratifying patients for cardiac risk prior to major non-cardiac surgery, the current clinical practice utilized for assessing patients being evaluated for kidney or pancreas transplantation is both a stress echocardiogram and a coronary angiogram. This gap in opinion appears to be a concern on the part of both nephrologists, endocrinologists, and surgeons that the stress echocardiogram may miss significant angiographic disease that could result in major post-operative complications in this high-risk subgroup of patients (unstable angina, non-fatal infarction, or death).
