Objectives To investigate demographic, clinical characteristics, treatment patterns and healthcare resource utilisation (HCRU) among patients with portopulmonary hypertension (PoPH). Design Retrospective analysis of a real-world cross-sectional survey, the pulmonary arterial hypertension (PAH) Disease Specific Programme. Setting Secondary care settings in the USA. Participants Pulmonologists (n=22), cardiologists (n=17) and internists (n=7) who saw ≥2 patients with PAH/month provided data on 90 PoPH patients. Mean age of patients was 56.8 years, 51.1% were male, 76.7% were white/Caucasian. Primary and secondary outcome measures Demographic characteristics, initial presentation/diagnosis, disease trajectory, symptoms, comorbidities, treatment patterns and HCRU. Results The most common diagnostic tests were echocardiogram (62.2%), right heart catheterisation (56.7%) and electrocardiogram (48.9%). Dyspnea on exertion (64.4%), dyspnea following exertion (51.1%) and fatigue (48.9%) were the most common symptoms prior to PAH diagnosis as well as the most bothersome. Overall, 13.3% patients had mild disease before treatment vs 42.2% at time of survey. Most (60.0%) had stable disease (21.1% were improving and 18.8% were deteriorating at the time of the survey). Most common recent symptoms were dyspnea on exertion (51.1%), fatigue (37.8%) and dyspnea following exertion (32.2%). Patients had a mean of 1.8 comorbidities. In total, 80.0% of PoPH patients were receiving PAH-specific treatment; 41.7%, 22.2% and 12.5% received monotherapy, dual therapy and triple therapy, respectively. Patients had seen their physician 4.1 times in the past 12 months (3.5 visits specifically for PAH), while 31.1% had been hospitalised for PAH. Most (70.0%) patients were managed in a multidisciplinary team, and 8.9% of patients relied on a caregiver. Conclusions This study highlights the high symptomatic burden coupled with mostly moderate-to-severe disease status and a high hospitalisation rate despite the majority of PoPH patients being on therapy. Therefore, new treatment options in PoPH are in great need.

Background The effectiveness of endovascular thrombectomy (EVT) for low Alberta Stroke Program Early CT score (ASPECTS) stroke patients with occlusion of the second segment of the middle cerebral artery (M2) is unclear. Methods This was a multicenter retrospective study. Patients with M1 or M2 occlusions and low ASPECTS (<6) who underwent successful EVT (modified treatment in cerebral ischemia score of 2b or higher) were included. Primary outcome was futile EVT reperfusion (defined as 90-day modified Rankin scale of 5 or 6). Other outcomes of interest include acceptable outcomes (modified Rankin scale of 3 or less) and intracranial hemorrhage (ICH), and all-cause 90-day mortality. Outcomes for M1 patients were compared to M2 patients with multivariable logistic regression models accounting for potential confounders. Results 173 patients with M1 or M2 occlusions and low ASPECTS (<6) who underwent successful EVT were identified. After multivariable adjustments, M2 patients had significantly higher odds of futile reperfusion (OR 5.48 [95%CI 1.91 to 15.7], p = 0.002), lower odds of acceptable outcomes (OR 0.33 [95%CI 0.12 to 0.89], p = 0.028), and higher odds of all-cause mortality (OR 4.90 [95%CI 1.65 to 14.5], p = 0.004). These findings suggest that EVT's efficacy for low-ASPECTS stroke patients may be diminished for patients with M2 occlusions. M2 occlusion was not significantly associated with ICH. Conclusions Among low-ASEPCTS stroke patients who underwent successful EVT, those with M2 occlusions had significantly higher odds of poor outcome compared to those with M1 occlusions.

Prosthetic heart valve (PHV) dysfunction is increasingly seen due to the increase in the number of PHV that are being implanted worldwide. Cardiac CT imaging has emerged as a valuable tool to assess PHVs and determine the cause of dysfunction. This consensus document first summarizes the available techniques for PHV assessment. Then the use of CT in PHV (dys)function assessment is discussed in detail including consensus statements for correct indications and patient selection for CT assessment of PHVs, image acquisition, reconstruction and measurement protocols and how to interpret and report the CT findings for specific types of PHV dysfunction.
