Right ventricular (RV) failure has become a deadly complication of left ventricular assist device (LVAD) implantation, for which desynchrony in bi-ventricular pulse resulting from a LVAD is among the important factor. This paper investigated how different control modes affect the synchronization of pulse between LV (left ventricular) and RV by numerical method. The numerical results showed that the systolic duration between LV and RV did not significantly differ at baseline (LVAD off and cannula clamped) (48.52%

External compression of the right ventricle (RV) due to a depressed sternum in patients with pectus excavatum is uncommon. Moreover, mid-RV obstruction-induced cachexia rarely occurs in patients with pectus excavatum. We report a case of cardiac cachexia caused by significant RV compression in a patient with pectus excavatum.

It has been well known that dilated cardiomyopathy (D-CMP) has characterized by systolic dysfunction of left ventricle (LV). But there are few studies about LV diastolic and right ventricular (RV) dysfunction in D-CMP. The purpose of this study is to assess the LV and RV systolic function as well as diastolic function in D-CMP. The purpose of this tudy is to assess the LV and RV systolic function as well as diastolic function in D-CMP. The gated blood pool scan (GBPS) was undertaken in 14 patients with D-CMP and 14 normal controls. The results are as follows : 1) Compared to normal controls, the global and regional ejection fraction of LV were significantly reduced (P<0.001) in D-CMP. But, there was no significant difference in LV ejection time between the two groups. 2) Peak filling rate and peak filling time were significantly reduced (P<0.001, P<0.05) in D-CMP 3) Global ejection fraction of RV was also significantly reduced in D-CMP compared to normal controls (P<0.001) But there was no significant difference in ejection rate of right ventricle between the two groups. 4) There was close correlation (R=0.802) between ejection fraction and filling rate of LV : filling rate was also reduced as ejection fraction decreased. And LV filling rate was also reduced with reduction of ejection rate. It is concluded that D-CMP shows diastolic impairment as well as systolic pumping failure and this systolic dysfunction is accounted for the diastolic impairment in D-CMP. And D-CMP shows also right ventricular dysfunction in almost all cases, as well as left ventricular dysfunction.

An acute pulmonary embolism (PE) and the apical ballooning syndrome (ABS) are both critical and need proper management during the acute stage. We experienced a case of recurrent severe dyspnea because serious right ventricular dysfunction due to PE and left ventricular dysfunction due to ABS occurred consecutively in the short-term and bedside echocardiography has an important role in management in acute settings.

Objective: To evaluate the right ventricular function using two-dimensional speckle tracking echocardiography (2-D STE) and analyze the associated risk factors of right ventricular dysfunction in patients with silicosis. Methods: All 104 patients with silicosis treated in the Department of Occupational Medicine and Toxicology in Beijing Chao-Yang Hospital, Capital Medical University from May 2021 to September 2022 were enrolled in this study in October 2022. The clinical information of patients such as general data, arterial blood gas analysis and pulmonary function test were collected. The right ventricular function of patients was evaluated by 2-D STE-derived right ventricular free wall longitudinal strain (RVFWLS) and conventional echocardiographic-derived parameters, including right ventricular fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE) and doppler tissue imaging-derived tricuspid lateral annular systolic velocity (S'), respectively. Based on their RVFWLS, the patients were divided into right ventricular dysfunction group and normal right ventricular function group. Risk factors for right ventricular dysfunction in patients with silicosis were analyzed using binary logistic regression analysis. Results: A total of 104 silicosis patients were enrolled, with aneverage age (65.52±11.18) years old, among whom including 57 cases diagnosed with stage Ⅰ/Ⅱ silicosis and 47 cases diagnosed with stage Ⅲ silicosis. 26 (25.00%) patients concurrent right ventricular dysfunction. The abnormal rates of RVFAC, TAPSE and S' in patients were 16.35% (17 cases), 21.15% (22 cases) and 6.73% (7 cases), respectively. The RVFAC and TAPSE in right ventricular dysfunction group were lower than those in normal right ventricular function group, and the incidence of pulmonary arterial systolic pressure ≥36 mmHg was higher than that in normal right ventricular function group (P<0.05). Logistic regression analysis showed that arterial partial pressure of oxygen (OR=0.932, 95%CI: 0.885-0.981, P=0.007) was the protective factor, and the forced expiratory volume in 1 second (FEV(1)) /forced vital capacity (FVC) ratio<70% (OR=5.484, 95%CI: 1.049-28.662, P=0.044) and stage Ⅲ silicosis (OR=6.343, 95%CI: 1.698-23.697, P=0.007) were the risk factors for silicosis patients concurrent right ventricular dysfunction. Conclusion: The incidence of right ventricular dysfunction is higher in patients with stage Ⅲ silicosis than that in patients with stage Ⅰ/Ⅱ silicosis. Using 2-D STE can help the early detection of silicosis with right ventricular dysfunction. Hypoxemia, airflow limitation and the stage Ⅲ silicosis are the risk factors for silicosis patients concurrent right ventricular dysfunction.

PURPOSE: Ebstein's anomaly is characterized by ongoing tricuspid regurgitation and right ventricular dysfunction. It is difficult to decide the proper time of surgical correction. The purpose of this study is to evaluate the advantage of early surgical correction of Ebstein's anomaly. METHODS: The clinical records of the sixteen patients, who had undergone tricuspid valvuloplasty with plication of the atrialized RV and followed-up for more than five years, were reviewed. Surgical outcome was analysed as regards year of surgery, age of the patients, echocardiographic grade of severity, Carpentier type, associated cardiac defects, and type of surgery. RESULTS: Of sixteen patients, eight patients underwent tricuspid valve repair before 5 years(8 months to 5 years, mean 2.4 years) of age(group A), and eight patients underwent tricuspid valve repair after 5 years(6 to 23 years, mean 12.9 years) of age(group B). Immediately after the operation, tricuspid incompetence regressed significantly in 5 of group A, and 5 of group B, and reduction in heart size was usual. After short and mid- term follow-up period, four of group A showed mild tricuspid valve regurgitation and right ventricular dilatation and relatively well preserved right ventricular function. However, all of group B showed severe right ventricular dilatation with severe tricuspid regurgitation and both ventricular dysfunction. All of group A were in New York Heart Association class I. However, in group B, only three were in class I. Two of group B died of right heart failure 10 and 16 years after the surgical correction, respectively. The year of surgery, mean follow-up periods, associated cardiac defects, and the preoperative echocardiographic grade of the severity were not different significantly between two groups. But there was a difference between two groups in the mean age of the patients, 12.7+/-5.2 years in group A, 21.7+/-5.5 years in group B. The surgical outcome was not closely related to Carpentier types of Ebstein's anomaly. CONCLUSION: Early repair of tricuspid valve may be advantageous to prevent progressive dilatation of the right side heart and to preserve right ventricular function after surgical correction. But the aging factor was not corrected in our study and it is still necessary to follow-up for a longer period in larger patients group.
