Safety and Effectiveness of a Peripheral Rheolytic Thrombectomy Catheter in ST-Segment Elevation Myocardial Infarction: A Case Series

TL;DR

A peripheral thrombectomy catheter was safely used in six patients with severe heart attacks, showing promise in reducing clot burden.

Contribution

Demonstrates the potential use of a peripheral rheolytic thrombectomy catheter for treating high-thrombus coronary lesions in heart attack patients.

Findings

The AngioJet Solent® Dista catheter effectively reduced thrombus burden in all six cases.

Mid-term follow-up showed no angina recurrence and minimal in-hospital adverse events.

One case of no-reflow occurred, but no major complications were observed.

Abstract

Percutaneous treatment of highly thrombotic coronary lesions is demanding, due to worse acute and long-term clinical outcomes. In this report, we describe a case series of six patients with ST-segment elevation myocardial infarction and high-thrombus-burden coronary lesions. All patients were treated with the AngioJet Solent® Dista catheter, a rheolytic thrombectomy device designed for peripheral use. The catheter effectively reduced the thrombus burden in all cases, achieving satisfactory final angiographic results. One case of no-reflow was observed following lesion dilatation prior to thrombectomy, but no other major in-hospital adverse events occurred. At mid-term follow-up, all patients remained free from angina. These preliminary findings suggest that this approach could represent a promising option for managing highly thrombotic coronary lesions, but further studies with larger populations and long-term follow-up are needed to confirm these results.
