NCT ID: NCT03245255 Completed - Heart Failure Clinical Trials

Noninvasive Real-time Intracardiac Pressure Measurements Using Subharmonic Ultrasound

Start date: December 4, 2017
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT03243942 Completed - Heart Failure Clinical Trials

Noninvasive, Subharmonic Intra-Cardiac Pressure Measurement

Start date: June 1, 2017
Phase: Phase 2
Study type: Interventional

The fundamental hypothesis of this project is that real-time intracardiac pressures can be monitored and quantified noninvasively in humans using a novel contrast-enhanced ultrasound technique called subharmonic-aided pressure estimation (SHAPE).This study will use contrast echocardiography to assess the accuracy of SHAPE compared to simultaneously acquired intracardiac 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.

NCT ID: NCT03115294 Completed - Heart Ventricles Clinical Trials

Digital Image Correlation in Right Ventricular Evaluation

CardiomeDIC
Start date: May 16, 2016
Phase: N/A
Study type: Interventional

Observational study of patients undergoing open heart surgery. During the procedure video clips of right heart are stored and compared to trans-oesophageal ultrasound recordings and ECG recordings.
