A rare case of catheter-induced infectious endocarditis of the right heart chambers complicated by embolism of the left pulmonary artery and its successful surgical treatment is presented. We performed the operation to remove a foreign body and vegetations from the superior vena cava and the right atrium, embolectomy from the left main branch of the pulmonary artery, chemical sanitation of the right chambers of the heart and pulmonary artery under extracorporeal circulation.

The successful operations upon abnormalities of the outflow tracts of the heart suggest that surgical measures may also be applied to the correction of abnormal inflow tracts. Technically the anastomosis of veins to the auricle has been proved feasible in the experimental animal. Therefore, it should be possible to correct abnormally placed pulmonary veins in man. A wide variety of such anomalies occur. In 55 of 136 reported cases, all the oxygenated blood from the lungs was returned to the right heart through anomalous vessels. Thirty-five per cent of these cases of complete diversion were accompanied by other major cardiac defects. It is estimated that 50% or more of the return flow from the lungs must reach the right heart to produce clinical symptoms. Two cases are presented of persistence of the left superior vena cava which transmitted all the freshly oxygenated blood to the right auricle, by way of the left innominate and the right superior vena cava. The clinical picture was that of growth retardation, minimal cyanosis, a huge hyperactive heart, a loud left mesocardial systolic murmur, pulsating shadows in both upper pulmonary fields, and nearly identical oxygen-saturation of blood obtained from the right heart and femoral artery. One case is reported in which all the oxygenated blood from the lungs is carried to the right auricle by way of the ductus venosus. Surgical correction of the abnormality of these cases by transplantation of one or more of the veins would have been possible. However, no case known to the authors has yet been successfully corrected.

Objective This study was performed to investigate the surgical treatment of intravenous leiomyomatosis involving the right heart. Methods The clinical data of five patients with intracardiac leiomyomatosis treated from April 2002 to October 2017 at a single center were retrospectively analyzed. Results All five patients underwent successful intravenous and right atrial tumor removal via abdominal and inferior vena cava incisions. In three patients, these incisions were combined with thoracotomy and a right atrial incision, and in two patients, they were combined with uterine and bilateral fallopian tube and ovarian resection. One patient with advanced disease underwent a one-stage procedure and died thereafter. Of the remaining four patients who underwent follow-up for 1.5 to 12.0 years, one developed recurrence at 1 year postoperatively. The recurrent tumor, which was pathologically confirmed to be an intravenous leiomyoma, was removed via inferior vena cava and internal iliac vein incisions without subsequent recurrence. Conclusions The main treatment goal for inferior vena cava leiomyomas involving the right heart is to first address the severe obstruction of cardiac blood flow and then pursue second-stage surgery. Concurrent thoracotomy appears unnecessary because moderately sized right heart tumors can be gently removed via the inferior vena cava.

Dilution Curves

The role of venous passage of indicator from different venous injection sites on the genesis of right heart and pulmonary artery dilution curves was examined. Right heart and pulmonary artery thermodilution curves were recorded after injection of cool dye into commonly used portals—superior vena caval, right atrial, and inferior vena caval—and the contour compared with the subsequent femoral artery dye dilution curve. With superior vena caval or right atrial injection, the contour and disappearance slopes of the pulmonary artery curve bore an extremely variable relationship to those of the femoral artery curve. In sharp contrast, inferior vena caval injection yielded pulmonary artery curves with disappearance slopes which were highly correlated with the femoral artery slope ( r = .99). With inferior vena caval injection, considerable temporal dispersion and spatial dispersion of indicator is found at the right atrial level. With superior vena caval injection distribution mainly occurred beyond the right atrium and even beyond the pulmonary artery in eight out of ten animal studies. The geometry of the venous system may explain this difference. Inaccuracies in flow calculation from right heart dilution curves in dogs would seem to be minimized by inferior vena caval injection.

Abstract Objective: This study is designed to explore the dual-source computed tomography (DSCT) imaging manifestations of the origin of three rare pulmonary artery abnormalities, and to improve the understanding and diagnosis of the disease.Methods: Collected 30 cases of patients diagnosed by DSCT with pulmonary artery abnormal origins, and retrospectively analyzed their imaging data and postoperative pathological data.Results: Among the 30 patients with abnormal pulmonary artery origin, 16 patients were with unilateral pulmonary artery absence (UAPA), 8 patients were with anomalous origin of unilateral pulmonary artery (AOPA), and 6 patients were left pulmonary artery suspension (LPAS). The diagnosis rate of DSCT is significantly higher than that of echocardiography. The results of DSCT imaging showed that the inner diameter of the ascending aorta, the aortic arch and the descending aorta of UAPA patients were significantly larger than those of LPAS patients (P<0.05). Compared with AOPA patients, the left pulmonary artery diameter, the ratio of the left main pulmonary artery diameter to the main pulmonary artery diameter, and ratio of the left main pulmonary artery diameter to the right main pulmonary artery diameter were significantly increased in UAPA patients (P<0.05). There was no significant difference in the ratio of the inner diameter of the ascending aorta to the descending aorta in patients with UAPA, AOPA and LPAS. Compared with UAPA patients, AOPA patients had no significant changes in the inner diameter of the main pulmonary artery, the inner diameter of the right main pulmonary artery, and the ratio of the inner diameter of the right main pulmonary artery to the main pulmonary artery.Conclusion: DSCT can be used to diagnose the origin of pulmonary artery abnormalities and distinguish its types.

Background & Objectives: To evaluate the advantages of the one and a half ventricle repair on maintaining a low pressure in the inferior vena cava district. Also evaluate the competition of flows at the superior vena cava – right pulmonary artery anastomosis site, in order to understand the hemodynamic interaction of a pulsatile flow in combination to a laminar one. Materials & Methods: Adult rabbits (n=30) in terminal anaesthesia with a follow up of 8 h were used, randomly distributed in three experimental groups: Group 1: animals with an anastomosis between superior vena cava and right pulmonary artery, as a model of one and one half ventricle repair; Group 2: animals with the cavopulmonary anastomosis followed by clamping of the right pulmonary artery proximal to the anastomosis; and Group 3: sham animals. Pressures of superior vena cava and pulmonary arteries were afterwards measured, in a resting condition as well as after induced pharmacological stress test.Results: In Group 1, superior vena cava pressure was significantly higher, while venous pressure in the inferior vena cava – right atrium district was constant or lower in comparison with the other groups. After stress test, the pressure in the superior vena cava and the heart rate both increased further, but the right ventricular, right atrial and pulmonary artery pressures remained similar to the values in a resting condition. This proved that the inferior vena cava return was well-preserved, and no venous hypertension was present in the inferior vena cava district even after stress test (good exercise tolerance).Conclusion: One and one half ventricle repair can be considered a good surgical strategy for maintaining a low pressure in the inferior vena cava district with potential for right ventricle growth, restoring the more physiological circulation in borderline or failing right ventricle conditions. The experiment presented a positive finding in favour of one and one half ventricle repair, as compared to Fontan type procedure.
