Abstract Background Pulmonary hypertension (PH) is a known co-morbidity in West Highland white terriers (WHWTs) affected with canine idiopathic pulmonary fibrosis (CIPF). The pulmonary vein-to-right pulmonary artery ratio (PV/PA) has recently been described for the detection of pre-capillary PH in dogs. The objective of the present study was to estimate the prevalence of PH at diagnostic, in WHWTs affected with CIPF, by using PV/PA, in comparison with a group of healthy breed-matched controls (CTRLs). Additional study objective was to explore whether the presence of PH at initial diagnosis of CIPF impacted survival time in dogs treated with sildenafil. Results Twenty-five client-owned WHWTs presented with CIPF and 19 CTRLs were included in the study. PV/PA in either two-dimensional mode (2D) or time-motion mode or both were measured from cineloops in each dog. Dogs were classified according to PV/PA value into non/mild PH (PV/PA measured in 2D ≥ 0.7) or moderate/severe PH (PV/PA < 0.7). Survival data of WHWTs affected with CIPF were extracted from medical record to assess association between presence of PH at diagnosis and outcome. 60 % overall prevalence for moderate/severe PH was estimated in this cohort of WHWTs presented with CIPF vs. 5 % in CTRLS (P = 0.0002). The presence of moderate/severe PH at initial presentation was not associated with survival. Conclusions Results of the present study confirm a high prevalence of PH at diagnosis in WHWTs affected with CIPF and highlight the utility of PV/PA as a non-invasive surrogate for assessment of PH in this population.

West Highland white terriers (WHWTs) affected with canine idiopathic pulmonary fibrosis (CIPF) are at risk of developing precapillary pulmonary hypertension (PH). In humans, thoracic computed tomography angiography (CTA) is commonly used to diagnose and monitor patients with lower airway diseases. In such patients, CTA helps to identify comorbidities, such as PH, that could negatively impact prognosis. Diameter of the pulmonary trunk (PT), pulmonary trunk-to-aorta ratio (PT/Ao), and right ventricle-to-left ventricle ratio (RV/LV) are CTA parameters commonly used to assess the presence of PH. Pulmonary vein-to-right pulmonary artery ratio (PV/PA) is a new echocardiographic parameter that can be used in dogs to diagnose PH. The primary aim of this study was to evaluate the use of various CTA parameters to diagnose PH. An additional aim was to evaluate the correlation of RV/LV measurements between different CTA planes. CTA and echocardiography were prospectively performed on a total of 47 WHWTs; 22 affected with CIPF and 25 presumed healthy control dogs. Dogs were considered to have PH if pulmonary vein-to-right pulmonary artery ratio (PV/PA) measured on 2D-mode echocardiography was less than to 0.7. WHWTs affected with CIPF had higher PT/Ao compared with control patients. In WHWTs affected with CIPF, PT size was larger in dogs with PH (15.4 mm) compared with dogs without PH (13 mm, p = 0.003). A cutoff value of 13.8 mm predicted PH in WHWTs affected with CIPF with a sensitivity of 90% and a specificity of 87% (AUC = 0.93). High correlations were observed between the different CTA planes of RV/LV. Results suggest that diameter of the PT measured by CTA can be used to diagnose PH in WHWTs with CIPF.

The Hamman-Rich syndrome is described in a 4-year-old Negro male. The clinical picture was that of persistent cough and progressive dyspnea beginning at 4 months of age. Diagnosis was made ante mortem by lung biopsy. The fibrotic process and arteriolosclerosis were more marked in the right lung. The disease may have been initiated by a bout of aspiration. There was accompanying stenosis of the right pulmonary artery and vein and occlusion of the lumen of the right pulmonary vein at its entrance to the left atrium. The hilar vascular findings are believed to be secondary to hilar areolar inflammation.

AbstractUnilateral interruption of pulmonary artery is a rare congenital anomaly which is usually associated with other congenital heart disease. Even more rarely it may occur in isolation. Most of the cases are incidentally detected in adulthood. Some cases develop pulmonary hypertension for yet unknown reasons; such cases usually present in infancy with right heart failure. Surgical correction in such cases is associated with adverse outcomes. Heart lung transplantation should be considered in such patients. We report a 3-year-old boy with interruption of right pulmonary artery with severe pulmonary hypertension and right heart failure who was considered for heart lung transplantation.

According to clinical features and ultrasonic imaging features of patients with absence of pulmonary artery, it is necessary to analyze ultrasonic imaging features of absence of pulmonary artery to provide clinical basis for improving the diagnostic value and prognosis. The data and color Doppler echocardiography of 45 patients with absence of pulmonary artery are collected, who are confirmed by cardiac catheterization, CTA and operation, and the clinical features and ultrasonic imaging features are studied. The research results show that 57% of the patients have left absence of pulmonary artery and 91% of them have other cardiovascular malformations, where ASD/PFO is the most common, PDA and VSD are the second. Patients with UAPA have changes of pulmonary artery, the incidence of pulmonary artery abnormalities in multiple malformations, changes of ASD/PFO, PDA and VSD are mainly pulmonary hypertension. The ejection fraction of patients with UAPA is normal. The main manifestation of pulmonary hypertension is the increase of right cardiac volume load, and the main manifestation of pulmonary stenosis is the increase of collateral circulation. Pulmonary hypertension and its associated cardiovascular malformations may be related to the prognosis of patients. Ultrasound doctors should understand such diseases to improve the diagnosis rate and the prognosis.
