ABSTRACT
AIMS: Aim of the study was to verify the feasibility, safety and efficacy of pulmonary endarterectomy (PEA) in octogenarian patients with chronic thromboembolic pulmonary hypertension. METHODS: We retrospectively analyzed 635 chronic thromboembolic pulmonary hypertension patients who underwent PEA at our center and were followed-up for at least 1 year. The end-points of the study were in-hospital mortality, hemodynamic results at 1 year and long-term survival. RESULTS: In-hospital mortality was 4, 10 and 17%, respectively, for 259 patients under the age of 60 years, 352 aged between 60 and 79 years and 24 octogenarians (Pâ=â0.006 octogenarians vs. <60 years). At multivariable analysis, age and pulmonary vascular resistances were independent risk factors for mortality (Pâ=â0.021 and Pâ<â0.001, respectively). At 1 year, the improvement in cardiac index was lower and the distance walked in 6âmin was poorer for octogenarians than for the other two groups (both Pâ=â0.001). Survival after hospital discharge was similar over a median follow-up period of 59 months (Pâ=â0.113). Although in-hospital mortality and long-term survival are similar in octogenarians as compared with patients aged between 60 and 79, the improvement in cardiac index and in functional capacity at 1 year are lower in this very elderly population. CONCLUSION: Age over 80 years should not be a contraindication to PEA surgery in selected patients operated on in referral centers.

BACKGROUND: After successful pulmonary endoarterectomy (PEA), patients may still suffer from exercise limitation, despite normal pulmonary vascular resistance. We sought to assess the proportion of these patients after the extension of PEA to frail patients, and the determinants of exercise limitation. METHODS: Out of 553 patients treated with PEA from 2008 to 2016 at our institution, a cohort of 261 patients was followed up at 12 months. They underwent clinical, haemodynamic, echocardiographic, respiratory function tests and treadmill exercise testing. A reduced exercise capacity was defined as Bruce test distance < 400 m. RESULTS: Eighty patients did not had exercise testing because of inability to walk on treadmill and/or ECG abnormalities Exercise limitation 12 months after PEA was present in 74/181 patients (41, 95%CI 34 to 48%). The presence of COPD was more than double in patients with exercise limitation than in the others. Patients with persistent exercise limitation had significantly higher mPAP, PVR, HR and significantly lower RVEF, PCa, CI, VC, TLC, FEV1, FEV1/VC, DLCO, HbSaO2 than patients without. The multivariable model shows that PCa at rest and TAPSE are important predictors of exercise capacity. Age, COPD, respiratory function parameters and unilateral surgery were also retained. CONCLUSIONS: After successful PEA, most of the patients recovered good exercise tolerance. However, about 40% continues to suffer from limitation to a moderate intensity exercise. Besides parameters of right ventricular function, useful information are provided by respiratory function parameters and COPD diagnosis. This could be useful to better address the appropriate therapeutic approach.

We report the case of a woman with pulmonary embolism due to a cardiac mass. Echocardiography, computed tomography scan, and cardiac magnetic resonance raised the suspicion of right atrial myxoma and confirmed the presence of pulmonary embolism. The patient was sent to the University of Pavia School of Medicine, where the atrial myxoma was excised, and, using interrupted periods of circulatory arrest, extraction of the myxoma emboli from the pulmonary arteries was performed. No adjuvant chemotherapy was required as surgical treatment is an effective therapy in cases of pulmonary embolism of a benign neoplastic mass.

BACKGROUND: In this prospective, single-center, observational study, we investigated the association between repeated short periods of circulatory arrest with moderate hypothermia during pulmonary endarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) and different neuropsychological dimensions. METHODS: We examined 70 patients with CTEPH, >18 to 80 years of age, who had been treated with PEA. Neuropsychological testing was performed. RESULTS: Learning ability and delayed memory remained well within the normal range for patients' age. We found a statistically significant post-surgical improvement in motor speed, which was accompanied by a better quality of life and reduced symptoms of depression and anxiety. CONCLUSION: PEA with repeated short periods of circulatory arrest in CTEPH did not result in any neuropsychological complications and may even lead to post-surgical psychological improvements.
