Long-term follow-up after Holmium:YAG laser revascularization combined with autologous bone marrow derived stem cells implantation.

Abstract

Background:

Coronary artery disease is a major cause of death worldwide. Despite different standard revascularization options, significant number of patients remains not suitable for any treatment. The aim of the study was to evaluate long-term outcome of patients with diffuse coronary artery disease, treated with autologous stem cells injections combined with transmyocardial laser revascularization.

Material and Methods:

9 patients underwent Holmium:YAG laser revascularization and autologous bone marrow derived stem cells implantation between 2007 and 2009 in the Department of Cardiovascular Surgery and Transplantology, John Paul II Hospital, Kraków and were subsequently followed up in 2015.

Results:

The mean follow-up period was 73 months. The mean CCS class significantly improved (1.4±0.5 vs 3.3±1.0; p<0.001) and cardiac related hospitalizations significantly decreased (1.1±0.8 vs 3.1±2.1; p<0.001). One death due to heart failure was observed. The mean LVEF increased from 38% to 42% (p>0.05).

Conclusions:

Clinical status improvement was observed with low mortality rate in the long-term follow-up. No new regional wall motion abnormalities were observed, and the increase of global ejection fraction was noted.
