Autologous Bone Marrow Transplanted Via Transendocardial Catheter to Chronic Myocardial Infarct Border Zone (TABMMI)

BioCardia

Status and phase: Completed; Phase 1

Conditions: Ventricular Dysfunction; Myocardial Infarction

Treatments: Procedure: Transendocaridal Transplantation of Autologous Bone Marrow

Study type: Interventional

Funder types: Industry

Identifiers

NCT00507468

ABM-MI-10

Details and patient eligibility

About

The object of this open-labeled, uncontrolled pilot study was to investigate the safety and feasibility of percutaneously transplanting autologous bone marrow (ABM) cells into the myocardium using the helical needle transendocardial (TE) delivery system in stable coronary patients with ventricular dysfunction due to chronic myocardial infarction (MI).

A secondary goal was to assess the possibility that such cell injections could improve ejection fraction (EF).
