ABSTRACT
BACKGROUND:
Bilateral pulmonary thromboendarterectomy(PTE) is recognized as the definitive treatment for chronic thromboembolic pulmonary hypertension (CTEPH). We investigated the symptomatic, hemodynamic and prognostic effects of PTE in comparison with medical treatment.METHODs:
Twenty-four patients diagnosed with CTEPH from 1995 to 2003 at the Asan Medical Center were divided into two groups patients treated with PTE(PTE group, n=12) and those not treated with PTE(Med group, n=12). The serial changes in dyspnea, the tricuspid regurgitation maximal velocity (TRVmax) and survival of the PTE and Med groups were compared retrospectively.RESULTS:
In PTE group, during a follow-up period of 1 year, the New York Heart Association(NYHA) functional class significantly improved, while there was no significant improvement in the Med group. PTE significantly lowered the TRVmax from 4.23+/-0.54 m/sec to 3.22+/-0.70 m/sec over a follow up period of 2 years. (p=0.028) However, the TRVmax in the medically treated group did not show any significant improvement, changing from 3.98+/-0.68 m/sec to 4.27+/-0.95 m/sec during 1 year. The 5-year survival of the PTE group was 77.9% compared with 64.3% in the medically treated group.CONCLUSION:
PTE provides substantial long-term improvement in dyspnea and the echocardiographic changes compared with medically treated patients.
