Abstract Purpose The purpose of this study was to explore the influence of cardiac cycle and the traditional risk factors on the four pulmonary veins (PVs) of adults and to determine the phase for measuring the maximum value of PVs. Methods Cardiac CT was performed in 101 subjects. The diameter, area, cross-sectional angle, and coronal-section angle of four PVs in 10 phase were reconstructed and measured at 10% step from 5%-95% R-R interval. The differences in PVs size and spatial angles in cardiac cycles and the correlation between the indicators of four PVs and traditional risk factors were analized using two-level model. Results All the maximum size values of the four PVs were found in 45%, while the minimum values were found in 5% or 95% of cardiac phases. Gender influenced the size of three PVs—right superior pulmonary vein (RSPV), right inferior pulmonary vein (RIPV), and left inferior pulmonary vein (LSPV). The diameter of the RSPV was small in hypertensive patients and smokers. In addition, the cross-sectional angles of the left superior pulmonary vein (LIPV) changed during cardiac cycles, and age affected these changes. We found no changes in the spatial angles of the RSPV, RIPV, and LSPV, as well as the coronal-section angle of the LIPV. Conclusions PVs ostia size of normal person varies during cardiac phases. Compared with nomal person, AF could affect the cardiac phase in which the maximum and minimum of PVs is, and it may lead to a reduction of the PVs’ size slightly. For life science journals only.

Pulmonary veins carry oxygenated blood from the lungs to the left atrium. Variations are quite common in the pattern of drainage. The present study was undertaken to evaluate the incidence of different draining patterns of the right pulmonary veins at the hilum by dissecting the human fixed cadaveric lungs. Clinically, pulmonary veins have been demonstrated to often play an important role in generating atrial fibrillation. Hence, it is important to look into the anatomy of the veins during MR imaging and CT angiography. In 53.8% of cases, the right superior lobar vein and right middle lobar vein were found to be united together to form the right superior pulmonary vein. In contrast to this, in 11.53% of cases, right middle lobar vein united with the right inferior lobar vein to form the right inferior pulmonary vein, while in 26.9% of cases, the right superior lobar vein, right middle lobar vein, and right inferior lobar vein drained separately.

Abstract Metastatic renal cell carcinoma with involvement through the pulmonary veins to the left atrium is very rare. We report the case of a 70-year-old male with metastatic renal cell carcinoma to the right lower lobe of the lung abutting the inferior pulmonary vein with extension to the left atrium without pre-operative evidence. Surgical resection was achieved through a posterolateral thoracotomy. Lung masses that abut the pulmonary veins should prompt further investigation with a pre-operative transoesophageal echocardiogram to minimize unexpected intraoperative findings.

ObjectivesWe sought to clarify the variations in the anatomy of the superior cavoatrial junction and anomalously connected pulmonary veins in patients with superior sinus venosus defects using computed tomographic (CT) angiography.MethodsCT angiograms of 96 consecutive patients known to have superior sinus venosus defects were analysed.ResultsThe median age of the patients was 34.5 years. In seven (7%) patients, the defect showed significant caudal extension, having a supero-inferior dimension greater than 25 mm. All patients had anomalous connection of the right superior pulmonary vein. The right middle and right inferior pulmonary vein were also connected anomalously in 88 (92%) and 17 (18%) patients, respectively. Anomalous connection of the right inferior pulmonary vein was more common in those with significant caudal extension of the defect (57% vs 15%, p=0.005). Among anomalously connected pulmonary veins, the right superior, middle, and inferior pulmonary veins were committed to the left atrium in 6, 17, and 11 patients, respectively. The superior caval vein over-rode the interatrial septum in 67 (70%) patients, with greater than 50% over-ride in 3 patients.ConclusionAnomalous connection of the right-sided pulmonary veins is universal, but is not limited to the right upper lobe. Not all individuals have over-riding of superior caval vein. In a minority of patients, the defect has significant caudal extension, and anomalously connected pulmonary veins are committed to the left atrium. These findings have significant clinical and therapeutic implications.

Abstract Postpneumonectomy syndrome can have a significant clinical impact on a patient. It presents as progressive dyspnoea due to compression of the contralateral bronchus and/or pulmonary veins. Herein, we present a patient who over a 2-year period developed progressive dyspnoea on exertion and eventually also at rest, due to compression of her left mainstem bronchus and her left inferior pulmonary vein. Surgical correction with implantable adjustable saline implants was undertaken to ameliorate her symptoms. Concurrent use of intraoperative transoesophageal echocardiography permitted real-time adjustment of the implants. This allowed objective measurement and demonstration of normalization of pulmonary vein velocity, which resulted in complete symptom resolution.

Background. Periodontitis is the most common chronic inflammatory condition worldwide and is associated with incident coronary disease.Hypothesis. We hypothesized that periodontal disease would also be associated with cardiac calcification, a condition which shares many risk factors with atherosclerosis and is considered a marker of subclinical atherosclerosis.Methods. Cross-sectional study at two sites (USA and Japan) involving subjects with both clinical echocardiograms and detailed dental examinations. Semiquantitative scoring systems were used to assess severity of periodontal disease and echocardiographic calcification.Results. Fifty-six of 73 subjects (77%) had cardiac calcifications, and 51% had moderate to severe periodontal disease (score > 2). In unadjusted analysis, a significant relationship between periodontal score and cardiac calcification (Spearman rho = 0.4,P=0.001) was noted, with increases in mean calcification score seen across increasing levels of periodontal disease. On multivariate logistic regression, adjusted for age, gender, race, glomerular filtration rate, and traditional risk factors, this association remained significant (P=0.024). There was no significant interaction by study site, race, or gender.Conclusions. In a multiracial population, we found a significant association between the degree of periodontal disease, a chronic inflammatory condition, and cardiac calcification. Further, higher periodontal scores were associated with greater degrees of calcification.

Abstract Background Haemoptysis is an uncommon presenting symptom in children and is usually caused by acute lower respiratory tract infection or foreign body aspiration. We report a rare case of right unilateral pulmonary vein atresia (PVA) as the underlying aetiology of recurrent haemoptysis in a child. Case presentation A 4 years old girl presented with history of recurrent haemoptysis. Bronchoscopic evaluation excluded a foreign body aspiration but revealed right bronchial mucosal hyperaemia and varices. Diagnosis of right unilateral PVA was suspected on transthoracic echocardiography which demonstrated hypoplastic right pulmonary artery and non-visualization of right pulmonary veins. Final diagnosis was confirmed on cardiac CT angiography. A conservative treatment approach was opted with consideration for pneumonectomy in future when she is older. Conclusion Rarer causes should be considered when investigating for recurrent haemoptysis in children. Bronchoscopy and cardiac imaging are useful tools to establish the diagnosis of unilateral PVA in our case.

Pulmonary vein (PV) stenosis is a rare disease with high recurrence and mortality rates. Objective. This study was aimed to evaluate the diagnostic accuracy of echocardiography versus cross-sectional modalities. Material and methods. Our study includes 11 consecutive patients who underwent a comprehensive PV anatomy assessment between April 2018 and June 2019 at Ukrainian Children’s Cardiac Center, Kyiv. Echocardiographic studies of each pulmonary vein followed by computed tomography (CT) or magnetic resonance imaging (MRI) were performed in all patients. A total of 27 CT/MRI studies were performed. Results. There were four patients whose echocardiography findings were completely confirmed by CT/MRI method. In some patients significant stenosis was underestimated by echocardiography. Sensitivity and specificity were 86.4 and 88.9 for echo, as well as 100 and 94.4 for CT/MRI, respectively. Conclusion. This study recognizes the limitations of echocardiography as an imaging tool for pulmonary veins morphology assessment. Cross-sectional studies overcome these limitations and provide excellent morphological as well as functional (MRI) evaluation of pulmonary veins.
