Right Heart Failure Indicative of Ebstein’s Disease in Adulthood about a Case

Ebstein disease is a rare congenital malformation whose clinical presentation differs according to the anatomical form and age of the patient. In adults, it presents mainly in the form of right or global heart failure or rhythm disorders. Survival is exceptionally long in some forms. We report the case of a 70-year-old patient with Ebstein’s disease in right heart failure.

Effects of Feixinning Capsules on BODE Index,CRP and Quality of Life in AECOPD Patients with Right Heart Failure

[Objectives]To investigate the therapeutic effect of Feixinning Capsules on acute exacerbation of chronic obstructive pulmonary disease(AECOPD)complicated with right heart failure.[Methods]A total of 60 cases of AECOPD patients with right heart failure and phlegm-heat syndrome were randomly selected as the study subjects,and were divided into the Feixinning group(n=30)and the control group(n=30).The Feixinning group was treated with Feixinning Capsules combined with conventional western medicine,and the control group was treated with conventional western medicine.The pulmonary function,CRP,CAT score,BODE index item index,and EQ-5D index were compared between the two groups before and after treatment.[Results]After treatment,the pulmonary function,CRP,CAT score,6MWD,mMRC,BODE score and EQ-5D index in the Feixinning group were significantly improved compared with the control group(P<0.05),and there was no statistical difference in the change of BMI index(P>0.05).[Conclusions]Feixinning Capsules can effectively improve the clinical symptoms and quality of life of patients with AECOPD complicated with right heart failure and phlegm-heat syndrome.

Twin pregnancy with sudden heart failure and pulmonary hypertension after atrial septal defect repair: A case report

BACKGROUND Pulmonary arterial hypertension(PAH)in pregnancy is one of the major obstetric complications and is considered a contraindication to pregnancy as it is classified as a class IV risk in the revised risk classification of pregnancy by the World Health Organisation.Pregnancy,with its adaptive and expectant mechanical and hormonal changes,negatively affects the cardiopulmonary circulation in pregnant women.Do patients with repaired simple congenital heart disease(CHD)develop other pulmonary and cardiac complications during pregnancy?Can pregnant women with sudden pulmonary hypertension be treated and managed in time?In this paper,we present a case of a 39-year-old woman who underwent cesarean section at 33 wk'gestation and developed PAH secondary to repaired simple CHD.Our research began by a PubMed search for"pulmonary hypertension"and"pregnancy"and"CHD"case reports.Three cases were selected to review PAH in pregnancy after correction of CHD defects.These studies were reviewed,coupled with our own clinical experience.CASE SUMMARY Herein,a case involving a woman who underwent atrial septal defect repair at the age of 34,became pregnant five years later,and had a sudden onset of PAH and right heart failure secondary to symptoms of acute peripheral edema in the third trimester of her pregnancy.As a result,the patient underwent a cesarean section and gave birth to healthy twins.Within three days after cesarean delivery,her cardiac function deteriorated as the pulmonary artery pressure increased.Effec-tive postpartum management,including diuresis,significant oxygen uptake,vasodilators,capacity and anticoagulants management,led to improvements in cardiac function and oxygenation.The patient was discharged from hospital with a stable recovery and transferred to local hospitals for further PAH treatment.CONCLUSION This case served as a reminder to obstetricians of the importance of pregnancy after repair of CHD.It is crucial for patients with CHD to receive early correction.It suggests doctors should not ignore edema of twin pregnancy.Also,it provides a reference for the further standardization of antenatal,in-trapartum and postpartum management for patients with CHD worldwide.

Establishment of adult right ventricle failure in ovine using a graded, animal-specific pulmonary artery constriction model

Background: Right ventricle failure(RVF) is associated with serious cardiac and pulmonary diseases that contribute significantly to the morbidity and mortality of patients. Currently, the mechanisms of RVF are not fully understood and it is partly due to the lack of large animal models in adult RVF. In this study, we aim to establish a model of RVF in adult ovine and examine the structure and function relations in the RV.Methods: RV pressure overload was induced in adult male sheep by revised pulmonary artery constriction(PAC). Briefly, an adjustable hydraulic occluder was placed around the main pulmonary artery trunk. Then, repeated saline injection was performed at weeks 0, 1, and 4, where the amount of saline was determined in an animal-specific manner. Healthy, age-matched male sheep were used as additional controls. Echocardiography was performed bi-weekly and on week 11 post-PAC, hemodynamic and biological measurements were obtained.Results: This PAC methodology resulted in a marked increase in RV systolic pressure and decreases in stroke volume and tricuspid annular plane systolic excursion, indicating signs of RVF. Significant increases in RV chamber size, wall thickness, and Fulton's index were observed. Cardiomyocyte hypertrophy and collagen accumulation(particularly type III collagen) were evident, and these structural changes were correlated with RV dysfunction.Conclusion: In summary, the animal-specific, repeated PAC provided a robust approach to induce adult RVF, and this ovine model will offer a useful tool to study the progression and treatment of adult RVF that is translatable to human diseases.
