Abstract

Background—: Chronic thromboembolic pulmonary hypertension leads to pulmonary hypertension and right-sided heart failure. The purpose of this study was to investigate the efficacy of percutaneous transluminal pulmonary angioplasty (PTPA) for the treatment of chronic thromboembolic pulmonary hypertension. Methods and Results—: Twenty-nine patients with chronic thromboembolic pulmonary hypertension underwent PTPA. One patient had a wiring perforation as a complication of PTPA and died 2 days after the procedure. In the remaining 28 patients, PTPA did not produce immediate hemodynamic improvement at the time of the procedure. However, after follow-up (6.0 ± 6.9 months), New York Heart Association functional classifications and levels of plasma B-type natriuretic peptide significantly improved (both P <0.01). Hemodynamic parameters also significantly improved (mean pulmonary arterial pressure, 45.3 ± 9.8 versus 31.8 ± 10.0 mm Hg; cardiac output, 3.6 ± 1.2 versus 4.6 ± 1.7 L/min, baseline versus follow-up, respectively; both P <0.01). Twenty-seven of 51 procedures in total (53%), and 19 of 28 first procedures (68%), had reperfusion pulmonary edema as the chief complication. Patients with severe clinical signs and/or severe hemodynamics at baseline had a high risk of reperfusion pulmonary edema. Conclusions—: PTPA improved subjective symptoms and objective variables, including pulmonary hemodynamics. PTPA may be a promising therapeutic strategy for the treatment of chronic thromboembolic pulmonary hypertension. Clinical Trial Registration—: URL: http://www.umin.ac.jp .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
