Comparing cardiac CT and transoesophageal echocardiography for detecting heart thrombi in stroke patients

Detecting Cardiac Thrombi in Acute Ischemic Stroke on Cardiac CT Versus Transoesophageal Echocardiography (MtH-DETECT)

Observational Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT06585228

This study is testing whether a heart scan called cardiac CT is better than a different heart test called TEE at finding blood clots in the hearts of stroke patients.

What this trial studies

This observational study aims to evaluate the effectiveness of cardiac computed tomography (CT) compared to transoesophageal echocardiography (TEE) in detecting cardiac thrombi in patients diagnosed with acute ischemic stroke. The study hypothesizes that cardiac CT may provide superior diagnostic yield due to its ability to visualize the left atrial appendage more effectively. Participants will undergo both cardiac CT and TEE to determine which method is more reliable for identifying thrombi that could lead to cardioembolic strokes. The study will include patients who have given informed consent and have been diagnosed with cardiac thrombus on initial imaging.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 years or older who have been clinically diagnosed with acute ischemic stroke and have a radiological diagnosis of cardiac thrombus.

Not a fit: Patients with conditions other than acute ischemic stroke or those with contraindications for TEE or repeat cardiac CT will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy for cardiac thrombi in stroke patients, potentially enhancing treatment outcomes.

How similar studies have performed: While there is limited data directly comparing cardiac CT to TEE for this specific purpose, the use of cardiac CT has shown promise in other studies for diagnosing cardiac conditions.
