Balloon pulmonary angioplasty improves prognosis by alleviating pulmonary hypertension in patients with chronic thromboembolic pulmonary hypertension, even with incomplete revascularization. However, hypoxia or the requirement for pulmonary vasodilators often remain even after pulmonary hypertension relief. With this cohort study, we aimed to examine whether complete revascularization by additional balloon pulmonary angioplasty on residual lesions, even after pulmonary hypertension relief, could resolve hypoxia or the requirement for pulmonary vasodilators. During complete revascularization with balloon pulmonary angioplasty in 42 patients with chronic thromboembolic pulmonary hypertension, we investigated therapeutic effects at baseline (T1), pulmonary hypertension relief phase (T2), and at 6 months post-final balloon pulmonary angioplasty (T3). The pulmonary hypertension relief phase was defined as the first time that a mean pulmonary artery pressure ≤ 25 mmHg or pulmonary vascular resistance ≤ 240 dyn-s/cm5 was reached in right heart catheterization before balloon pulmonary angioplasty. The partial pressure of oxygen increased progressively over T1, T2, and T3 (59.2±8.5, 69.0±9.7, and 80.0±9.5 mmHg, respectively; P<0.001 T2 vs. T3). Minimum oxygen saturation levels during the 6-minute walk distance test were 87% (81‒89%), 88% (84‒92%), and 91% (89‒93.3%), respectively (P<0.001 T2 vs. T3), with gradual increase in the 6-minute walk distance (346±125 m, 404±90 m, 454±101 m, respectively; P<0.001 T2 vs. T3). The percentages of patients using pulmonary vasodilators (54.8%, 45.2%, 4.8%, respectively; P<0.001 T2 vs. T3) and requiring oxygen therapy (26%, 26%, 7%, respectively; P = 0.008 T2 vs. T3) decreased significantly without hemodynamic exacerbation or major complications. Despite the discontinuation of pulmonary vasodilators, mean pulmonary artery pressure improved (36.0 [31.0‒41.3], 21.4±4.2, 18.5±3.6 mmHg, respectively; P<0.001 T2 vs. T3). Complete revascularization with balloon pulmonary angioplasty beyond pulmonary hypertension relief benefits patients with chronic thromboembolic pulmonary hypertension; it may improve oxygenation and exercise capacity, and reduce the need for pulmonary vasodilators and oxygen therapy.

Wedge Pressure

Chronic thromboembolic pulmonary hypertension (CTEPH) is defined as a mean pulmonary artery pressure ≥25 mm Hg and pulmonary artery wedge pressure ≤15 mm Hg in the presence of occlusive thrombi within the pulmonary arteries. Surgical pulmonary thromboendarterectomy (PTE) is considered the best treatment option for CTEPH.

Cardiac Masses

Right heart thrombus (RHT) accompanied by chronic thromboembolic pulmonary hypertension (CTEPH) is a rare entity. RHT may develop in the peripheral veins or in situ within the right heart chambers. The diagnosis of RHT is challenging, since its symptoms are typically non-specific and its imaging features resemble those of cardiac masses. Here, we report two cases of RHT with CTEPH that presented as right ventricular masses initially. Both patients underwent simultaneous pulmonary endarterectomy (PEA) and resection of the ventricular thrombi. Thus, when mass-like features are confirmed by imaging, RHT should be suspected in patients with CTEPH, and simultaneous RHT resection is required along with PEA.

Thromboembolic Pulmonary Hypertension

Abstract Atrial fibrillation (AF) and atrial tachycardia (AT) are frequently observed in patients with chronic thromboembolic pulmonary hypertension (CTEPH) who were treated with pulmonary endarterectomy (PEA). Their prevalence and impact on prognosis of patients are not known. We analysed the prevalence of AF/AT and the clinical outcome in 197 patients with CTEPH treated with PEA (median age 62; interquartile range 53–68 years; 62% males). The prevalence of AF/AT was 29% (57 patients). Compared to patients without arrhythmia, the subjects with AF/AT were older [60 (50–67) vs. 62 (57–70) years], manifested an increased size of the left atrium [39 (35–44) vs. 45 (40–50) mm], had a reduced 6-min walking distance [411 (321–506) vs. 340 (254–460) m], and higher pulmonary artery systolic pressure after PEA [38 (30–47) vs. 45 (38–71) mmHg], all results with P-value &lt;0.05. During the follow-up with a median 4.2 (1.6–6.3) years, 45 (23%) patients died. In a multivariate Cox regression model only the male gender [hazard ratio (HR) 2.27, 95% confidence interval (CI) 1.15–4.50], a reduced 6-min walking distance (HR 3.67, 95% CI 1.74–7.73), and an increased New York Heart Association class (HR 8.56, 95% CI 4.17–17.60) were associated with mortality (P &lt; 0.05). The prevalence of AF/AT in patients with CTEPH treated with PEA is high. Arrhythmias are associated with reduced functional capacity but not with mortality.
