Anomalous Pulmonary Venous Connection

The clinical, cardiac catheterization, and postmortem findings are presented in a 9-day-old infant with cor triatriatum, anomolous pulmonary venous connections, and a hypoplastic left ventricle. The dorsal accessory left atrial chamber did not communicate with the ventral or proximal left atrium, but did have a small connection with the right atrium. The left superior pulmonary vein connected with the accessory left atrium while the left inferior pulmonary vein connected with the proximal left atrium. The latter pulmonary venous connection has not been described previously in classical cor triatriatum and raises new embryological considerations.

Abstract We present the case of a 79 years old male patient affected by a lung squamous cell carcinoma (T4 N0 M1a) diagnosed in december 2018 with a 5x5 cm mass in the inferior lobe of the left lung close to the pericardium and a second 5 cm mass in the apical lobe of the right lung. TT echocardiography at that time was normal. Treatment with gemcitabine was scheduled with slight progression of the disease at the CT scan control in april 2019 when initial invasion of the left inferior pulmonary vein was detected. An ECG performed during routine control revealed the presence of q waves and ST segment elevation in the inferior leads. The patient was asymptomatic about the heart but the blood tests revealed a slight increase of HS Troponin I. We decided to repeat the TT echo, which showed the presence of a rounded mobile mass of about 3x2.5 cm in the left atrium close to the upper left pulmonary vein and another formation of about 5x2 cm infiltrating the inferior wall of the left ventricle that appeared akynetic. Both metastatic and thrombotic origins were debated and anticoagulant therapy with LMWH was started. We chose to perform a TE echocardiography, which confirmed the presence of the rounded mass in the left atrium, enlarged as compared to the TT evaluation. At the 3D reconstruction, it appeared to come from the left inferior pulmonary vein, completely occluding it, and expanding to the left superior vein, narrowing but not closing its orifice. The mass was well delimitated, disomogenous and vacuolated, thus confirming its likely neoplastic origin. From the trans-gastric view, we confirmed the large infiltration of the inferior wall of the left ventricle. General conditions of the patients quickly deteriorated and he experienced an ischemic stroke. At the TT echo re-evaluation the mass in the left atrium was greatly reduced as compared to the previous control. Cardiac metastases are a rare and frequently clinically silent occurrence; However, in a minority of cases they may present with ECG alterations such as ST-T segment modifications. In neoplastic patients an ischaemic ECG pattern not following its typical progression, without typical symptoms of ischaemia should rise the suspicion of a cardiac metastasis. In our case the abnormalities could be caused by a loss of viable myocardium secondary to the infiltrating mass or by a compression of the right coronary artery. In this context the echocardiography, both TT and especially TE, is a valuable tool that allow to recognize the real cause of these abnormalities and provides useful informations that enable to distinguish neoplastic mass from a thrombus. The ischaemic stroke was probably due to an embolization of the mass from the left atrium, as confirmed by its important reduction at the last echo control. Abstract P231 Figure.

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.

AbstractPartially anomalous pulmonary venous connection of a solitary pulmonary vein in the setting of an intact atrial septum is often subclinical, and the indications for surgical repair are controversial. Here we describe a patient who developed a significant shunt over a period of 10-years. Flow through the anomalously connected pulmonary segment depends on the difference of pressure between the right and left atrium, and may increase with age.

AbstractHepatoblastoma is the most common malignant liver tumour in early childhood. The metastatic extension of hepatoblastoma into the left atrium via the pulmonary vein is rare. Reported lesions almost always involve a right-sided approach. Here we report the case of a 3-year-old girl with a recurrent hepatoblastoma at multiple sites, including the left atrium, brain, and lung. The patient was treated surgically for the prevention of further embolic complications and cardiac failure.
