AbstractThe procedure of total cavopulmonary connexion includes trans-section and closure of the pulmonary trunk, the systemic venous blood flow being directed to the pulmonary vascular bed by an anastomosis of the superior caval vein with the right pulmonary artery. Following this procedure, there remains a small residual pulmonary trunk. The purpose of our study was to obtain information about the fate of this residual trunk and its contained pulmonary valve. Using transthoracic echocardiography, we examined 29 patients (mean age 7 years 4 months) after a total cavopulmonary connexion (mean interval 17 months). We were able to obtain adequate visualization of the pulmonary valve and the pulmonary trunk in 23 of the patients. Pulmonary regurgitation was demonstrated by colour Doppler echocardiography in 13 pts (57%). Formation of thrombus in the residual pulmonary trunk was detected in one patient (4%) 6 months after the operation. One cerebrovascular embolic event occurred in a patient who had pulmonary regurgitation without formation of thrombus in the residual trunk 3 months after the total cavopulmonary connexion. Our findings show that pulmonary regurgitation is frequently present in patients after total cavopulmonary connexion. Although formation of thrombus in the residual pulmonary trunk seems to be less common, we recommend surgical closure of the pulmonary valve during this procedure so as to exclude the residual pulmonary trunk as a possible source of systemic emboli.

Abstract A 77-year-old female, known hypertensive and dyslipidemic on treatment presented with three episodes of syncope in the last two months. On examination; there was grade 4/6 harsh systolic murmur on the lateral sternal border. Transthoracic echocardiography was difficult because of mesocardia and abnormal rotation of the heart due to enlarged right sided chambers. There is mild left ventricular hypertrophy with normal ejection fraction, no left sided valvular disease. The right ventricle was hypertrophied and dilated with normal RV function. The pulmonary valve was thickened with significant systolic flow aliasing through the valve with significant regurgitation and huge main pulmonary trunk aneurysm (59 mm at its wideset diameter) (Figure 1). Transthoracic approach did not allow a correct alignment of the Doppler CW and the correct estimate of pulmonary valvulopathy; TEE was performed with a correct visualization of the valve in deep transgastric projection at 90 degrees. The valve was thickened, fibrotic, degenerated with systolic doming of leaflets (Figure 2) and peak systolic gradient ∼ 70 mmHg (Figure 3). 3D reconstruction of the valve showed a tricuspid valve (Figure 4) with a valve area ∼ 0.9 cm2 using planimetry in MPR (Figure 5). CT scan was performed which confirmed the main pulmonary trunk aneurysm ∼ 60 mm (Figure 6). Therefore, in light of the clinical and instrumental picture, the patient was referred to heart team discussion for the plan of surgical intervention. Discussion According to the ESC guidelines for grown up congenital heart disease in 2010, this pulmonary valve should be intervened upon as it is severe symptomatic PS (1), but there are 2 problems with this case; the first is significant associated PR, so no place for balloon dilatation here, the second problem is the pulmonary artery aneurysm (PAA). The dilemma of management of pulmonary PAA is that all the available data are about aortic aneurysms. Indications for intervention for PAA include: Absolute PAA diameter ≥ 5.5 cm, Increase in the diameter of the aneurysm of ≥ 0.5 cm in 6 mo, Compression of adjacent structures, Thrombus formation in the aneurysm sack, Evidence of valvular pathologies or shunt flow Verification of PAH, Signs of rupture or dissection (2). Surgery could include: Aneurysmorrhaphy only decreases the diameter of the vessel (3). Aneurysmectomy and repair or replacement of the right ventricular outflow tract is commonly used technique recently and mostly suits connective tissue disorders (6). Also, Replacement of the PA and the pulmonary trunk with a conduit (Gore-Tex or Dacron tubes, homografts, or xenografts) starting in the right ventricular outflow tract with replacement of the pulmonary valve (4). Conclusion PAA management is currently challenging because there are no clear guidelines on its optimal treatment. The presence of significant pulmonary valve dysfunction could affect the decision making of the associated PAA management. Abstract P180 Figure.

Abstract Pulmonary embolism is one of the leading causes of maternal mortality despite a low incidence of during pregnancy. We present 32-year-old woman, in the 35 week of first pregnancy, admitted to the Intensive Care Unit with dyspnea, tachycardia, cyanosis. Echocardiography confirmed the presence of embolic material in the main trunk of pulmonary artery, spreading to the right pulmonary artery. D-dimer and troponin T level were elevated, BNP remained within the normal range. The risk in PESI scale was assumed as intermediate high. LMWH therapy was initiated, the patient was constantly monitored. Venous thrombotic disease in lower extremities was excluded by ultrasonography. The treatment was carried out under obstetric supervision. The clinical state gradually improved, the patient was hemodynamically stable. Serial echocardiographic testing, revealed gradual regression of changes in the pulmonary trunk. Normalization of troponins and lowering of BNP levels were observed. The pregnancy was terminated in 39 week, by cesarean section (obstetric indications). The LMWH was continued few days after delivery, as the patient started lactation. She decided to terminate lactation in a first week after delivery so the therapy was switched into rivaroxaban for at least 3 months. Echocardiography after 3 month confirmed lack of changes in pulmonary trunk, the risk of pulmonary hypertension was low. Echocardiography can be a method of choice for confirming and monitoring pulmonary embolism during pregnancy, in a situation of high or intermediate clinical risk and good visualization of changes in pulmonary arteries Abstract P701 Figure.

Relationship Of

In the normal heart, the morphologically right ventricle supports the pulmonary trunk. The key to echocardiographic evaluation of the junction between these structures is to understand not only the arrangement of the pulmonary valve, but also the complete muscular infundibulum that supports the valvar leaflets, lifting the valvar complex away from the base of the ventricular mass. As explained in the previous review,1 it is the presence of this free-standing muscular infundibular sleeve that makes it possible for the surgeon to remove the pulmonary valve for use as an allograft in the Ross procedure.2 In this review, we will address the echocardiographic features of the junction, considering primarily the situation in which the morphologically right ventricle supports the pulmonary trunk, but making comparisons with the abnormal arrangements in which either the aorta, or both arterial trunks, arise from the right ventricle. As we will see, the basic arrangement of the free-standing complete muscular infundibulum, or conus, is preserved with these abnormal arrangements, but there can be variation depending on the precise arrangement of the inner heart curvature, or ventriculo-infundibular fold, and the morphology can be further changed depending on the relationship of the arterial trunks themselves. The key to analysis, therefore, and also to accurate description, is to analyse separately the way in which the arterial trunks are joined to the ventricular mass, the relationships of the trunks one to the other, and the precise structure of the supporting right ventricular outflow tract, or outflow tracts in the setting of double outlet connection. If each of these features is then described in its own right, avoiding the temptation to make inferences regarding one feature from knowledge of another, then it is possible to avoid many of the persisting controversies relating to nomenclature.

Objective. To examine venous blood flow velocity in different types of fetal hydrops and its value in the prediction of outcome of pregnancies.Methods. Venous Doppler sonography was performed in 100 hydropic fetuses from 15 to 37 weeks of gestation. Blood velocity was recorded in the right hepatic vein (HV), the ductus venosus (DV) and in the intra-abdominal part of the umbilical vein (UV). Blood velocity indices were calculated and pulsations in the umbilical vein noted and grouped into a single, double or triple flow pattern. Blood velocity was related to cause of hydrops.Results. Mortality was noted in 51 cases of which 19 were by termination of pregnancy. Mortality in the 30 with normal venous blood velocity was 35%, but 58% in cases of abnormal Doppler. Abnormal HV and DV blood velocities were recorded in 39 and 34 cases, respectively and were strongly related to mortality ( and , resp.). UV pulsations were noted in 49 fetuses and were significantly related to mortality (). Mortality and abnormal venous velocities were most frequent in the low-output hydrops group (79% and 75%, resp.).Conclusions. Abnormal venous blood velocity is related to mortality in pregnancies complicated by fetal hydrops. Venous Doppler sonography should be a part of the routine work-up of pregnancies complicated by fetal hydrops.

Abstract Methods and results A 70-year-old woman presented to our outpatient clinic complaining of worsening dyspnoea in the last 3 months. She had a medical history of hypertension, diabetes, dyslipidemia, and paroxysmal atrial fibrillation. We performed a comprehensive evaluation starting with a transthoracic echocardiogram that showed a dilatation of right ventricle with normal function, severe pulmonary regurgitation, and moderate tricuspid regurgitation with estimated pulmonary artery systolic pressure of 55 mmHg; the left ventricle had normal dimension and function, with mild aortic and mitral regurgitation, and a subaortic membrane which caused a mild obstruction (maximum gradient 17 mmHg). The cardiac magnetic resonance (CMR) confirmed the enlargement of the right ventricle and of the pulmonary artery trunk (51 mm) and the severity of pulmonary regurgitation (regurgitant fraction of 41%). CMR also clearly showed the VSD just below the subaortic membrane and the left to right shunt with a jet that appeared to proceed straight from the left ventricle through the pulmonary valve (Figure 1A). The estimated Qp/Qs was 1.6 and no intramyocardial late enhancement was present. Pulmonary pressures and pulmonary vascular resistance were normal at the right heart catheterization and the Qp/Qs ratio calculated invasively was 1.45. Considering patient high-risk profile for coronary artery disease, a coronary angiography was also performed showing an abnormal origin of the right coronary artery (RCA) from the mid-portion of the left anterior descending coronary artery (LAD) with two significant stenosis: one involving the bifurcation of RCA and the other the mid-portion of the LAD (Figure 1B). The coronary computed tomography angiography (CCTA) showed a benign course of the RCA anterior to the pulmonary artery towards the auriculoventricular groove (Figure 1C, D). Taking into account all these findings, multidisciplinary heart team decided to perform a cardiac surgery intervention of pulmonary valve and trunk replacement, closure of ventricular septal defect and two coronary bypass grafts on LAD and RCA. Conclusions This case represents a combination of some rare congenital heart abnormalities where multimodality cardiovascular imaging techniques were essential to establish a proper diagnosis and to plan an adequate surgical repair. We hypothesize that the peculiar orientation of the VSD jet may have caused the pulmonary trunk dilatation considering that neither the shunt, nor the pulmonary pressure appear to have been of sufficient magnitude to cause it. Pulmonary ectasia and the damage inflicted by the jet to the cusps of the valve have led to the severe valvular insufficiency. While aortic and tricuspid regurgitation are known to be associated with VSD, to the best of our knowledge this is the first report of pulmonary regurgitation secondary to VSD.

We report a case of a partial anomalous left pulmonary artery sling in an adult patient as an incidental finding on computed tomography. There is a normal bifurcation of the pulmonary trunk into right and left pulmonary arteries with anomalous origin of the left upper lobe pulmonary artery from the right pulmonary artery. The anomalous vessel passes between the trachea and esophagus forming a partial left pulmonary artery sling without airway compression.
