Brief Summary
This study will use contrast echocardiography to assess the accuracy of a new non-invasive imaging method for subharmonic aided pressure estimation (SHAPE) compared to simultaneously acquired intra-cardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast echocardiography using the SHAPE method, already proven in a canine model and tested in a human pilot study can be used as a surrogate for cardiac catheterization with sufficient accuracy to allow clinical applicability in humans.

Outcome Measures
Primary Outcomes (2)
Agreement Between SHAPE and Pressure Catheter Measurements
The Pearson correlation coefficient was computed between the simultaneously acquired subharmonic signal and pressure catheter data (i.e., waveforms) for each participant. The Pearson correlation coefficient was used for comparing waveforms given the underlying data and pressure values used for comparisons followed a normal distribution. Values reported will be the mean Pearson correlation coefficient values between the subharmonic waveforms and pressure catheter waveforms obtained.
up to 1 day
Error Between SHAPE and Pressure Catheter Measurements
Based on the distribution of the differences in cardiac pressure values obtained using the SHAPE technique and the clinical pressure catheter, either a two-tailed paired t test (normal distribution) or Wilcoxon signed rank test (nonnormal distribution) was used to compare the SHAPE technique to the reference standard. Bonferroni corrections were used for multiple comparisons

Study Arms (1)
Sonazoid for pressure measurements
EXPERIMENTAL48 µl of Sonazoid microbubbles (GE Healthcare, Oslo, Norway) will be co-infused at a rate of 0.024 µl/kg body weight/minute together with a 0.9% sodium chloride solution infused at a rate of at least 2 ml/min.
Interventions
Whenever a patient undergoes cardiac catheterization, which routinely includes intracardiac pressure monitoring using a pressure catheter, as part of their standard clinical care and agrees to participate in the study, we will acquire research data. With Sonazoid infusion, SHAPE algorithm will be initiated to determine optimum acoustic pressure. Then, at the optimum acoustic pressure, SHAPE specific data will be acquired from the cardiac chambers and aorta synchronously with the pressures recorded by the catheter (as a part of the patient's standard of care). After acquiring the ultrasound imaging data, the remainder of the heart catheterization will be completed by the attending cardiologist according to the patients' standard of care.

You may not qualify if:
- Clinically unstable patients, e.g., those who are clinically in decompensated heart failure or having active chest pain or presenting for admission with an unstable anginal syndrome
- Patients in whom introduction of a catheter into the left ventricle is contraindicated or would potentially be dangerous, e.g., patients with active ventricular arrhythmias or with significant aortic valve stenosis where crossing the aortic valve may be difficult and not clinically necessary

- Patients who have received an investigational drug in the 30 days before, or will receive one within 72 h after, study drug administration.

- Patients with a history of anaphylactic allergy to eggs or egg products, manifested by one or more of the following symptoms: generalised urticaria, difficulty in breathing, swelling of the mouth and throat, hypotension, or shock. (Subjects with nonanaphylactic allergies to eggs or egg products may be enrolled in the study, but must be watched carefully for 1 h following the administration of SONAZOID).
- Patients with congenital heart defects.
- Patients with severe emphysema, pulmonary vasculitis, or a history of pulmonary emboli.
- Patients with respiratory distress syndrome or a contraindication to pharmacological vasodilator stress agents.
- Patients with thrombosis within the hepatic, portal, or mesenteric veins.

This project will generate pressure values in the aorta, and left and right ventricles using the proposed research method (i.e., SHAPE) and using the standard of care (i.e., catheter based pressure values). Additionally peripheral and central pressures will be generated. All of the pressure values will be made available. Further, all ultrasound data obtained for SHAPE measurements will be made available after anonymizing the data-set to remove any patient information
