  • Perioperative echocardiographic evaluation standard for transapical transcatheter aortic valve replacement

    Transcatheter aortic valve replacement (TAVR) has entered a new and critical stage after nearly 20 years of rapid development in China. There are various types of TAVR valves with different advantages. TAVR can be performed through various approaches such as transfemoral artery, transapical, trans-carotid artery, or trans-ascending aorta. The first two are more common. Echocardiography plays an important role in the perioperative period of TAVR. Compared to transfemoral approach, transapical TAVR has different key points in perioperative echocardiography which is lack of unified and accurate standards. This standard is specially formulated to focus on the key points of echocardiography in preoperative screening, intraoperative monitoring and postoperative follow-up in order to promote the safe and effective application of transapical TAVR in the clinic.

  • Analysis of 30-day mortality risk and development of a nomogram prediction model for elderly patients with heart failure and reduced ejection fraction after coronary artery bypass grafting

    Objective To investigate the 30-day mortality risk factors in elderly patients (≥70 years) with heart failure with reduced ejection fraction (HFrEF) after isolated coronary artery bypass grafting (CABG) and to construct a nomogram for predicting mortality risk. Methods A retrospective analysis of elderly HFrEF patients undergoing isolated CABG at Tianjin Chest Hospital from 2010 to 2024. Simple random sampling in R was used to divide the dataset into training and validation sets in a 7 : 3 ratio. The training set was further divided into survivors and non-survivors. Univariate logistic regression was performed to identify differences between groups, followed by multivariate logistic stepwise regression to select independent risk factors for death and to establish a death-risk nomogram, which underwent internal validation. The predictive value of the nomogram was assessed by plotting receiver operating characteristic (ROC) curves, calibration curves, and decision-curve analyses for both the training and validation sets. ResultsA total of 656 patients were included. The training set consisted of 458 patients (survivors 418, deaths 40); the validation set consisted of 198 patients (survivors 180, deaths 18). In the training cohort, univariate analysis showed significant differences between survivors and deaths for creatinine (Cr) level, brain natriuretic peptide (BNP), maximum Cr, intra-aortic balloon pump (IABP) use, assisted ventilation, reintubation, hyperlactatemia, low cardiac output syndrome, and renal failure (P<0.05). After multivariable logistic regression with stepwise selection, five independent risk factors were identified: IABP use (OR=3.391, 95%CI 1.065–11.044, P=0.038), reintubation (OR=15.991, 95%CI 4.269–67.394, P<0.001), hyperlactatemia (OR=8.171, 95%CI 2.057–46.089, P=0.007), Cr (OR=4.330, 95%CI 0.997–6.022, P=0.024), and BNP (OR=1.603, 95%CI 1.000–2.000, P=0.010). Accordingly, a nomogram predicting mortality risk was constructed. The ROC and calibration analyses indicated good predictive value: training set AUC was 0.898 (95%CI 0.831–0.966); validation set AUC 0.912 (95%CI 0.805–1.000). Calibration and decision-curve analyses showed good agreement and clinical utility. Conclusion The nomogram incorporating IABP use, reintubation, hyperlactatemia, creatinine, and BNP provides good predictive value for 30-day mortality after CABG in elderly patients with HFrEF and demonstrates potential clinical utility.

  • 2024 expert consensus on clinical pathway for transcatheter aortic valve replacement in China

    We update the "2021 expert consensus on clinical pathway for transcatheter aortic valve replacement in China" using the Delphi method. By searching for evidence related to the clinical pathways of transcatheter aortic valve replacement (TAVR) in PubMed, CIKI, and Wanfang Database over the past four years, 35 core viewpoints were proposed in four directions: TAVR team composition and clinical evaluation, perioperative imaging assessment, surgical process, and perioperative and postoperative long-term management of patients. The specific updates include: refining the responsibilities and composition of the TAVR team, clarifying the steps and content of clinical evaluation; emphasizing the core position of CT in perioperative imaging assessment, and introducing the application of new technologies such as artificial intelligence, numerical simulation, and 3D printing; optimizing the TAVR surgical process, including anesthesia selection, access establishment, valve selection and release, and others; and proposing management strategies for special types of patients (such as emergency TAVR, simplified TAVR, pure aortic regurgitation, combined coronary heart disease and atrial fibrillation). In addition, the consensus also emphasizes the importance of postoperative follow-up and rehabilitation, and provides detailed antithrombotic and rehabilitation guidance. The update of this consensus will further promote the standardized development of TAVR technology in China and improve clinical treatment effects.

    ObjectiveTo investigate the effect and safety of tranexamic acid sequential rivaroxaban on perioperative blood loss and preventing thrombosis for elderly patients during lumbar interbody fusion (LIF) with a prospective randomized controlled study.MethodsBetween April and October 2019, the elderly patients with lumbar degenerative diseases requiring LIF were included in the study, among which were 80 patients met the selection criteria. According to the antifibrinolysis and anticoagulation protocols, they were randomly divided into a tranexamic acid sequential rivaroxaban group (trial group) and a simple rivaroxaban group (control group) on average. Finally, 69 patients (35 in the trial group and 34 in the control group) were included for comparison. There was no significant difference in general data (P>0.05) such as gender, age, body mass index, disease duration, diseased segment, type of disease, and preoperative hemoglobin between the two groups. The operation time, intraoperative blood loss, drainage within 3 days after operation, perioperative total blood loss, and proportion of blood transfusion patients were compared between the two groups, as well as postoperative venous thrombosis of lower extremities, pulmonary embolism, and bleeding-related complications.ResultsThe operations of the two groups completed successfully, and there was no significant difference in the operation time (P>0.05); the intraoperative blood loss, drainage within 3 days after operation, and perioperative total blood loss in the trial group were significantly lower than those in the control group (P<0.05). The proportion of blood transfusion patients in the trial group was 25.71% (9/35), which was significantly lower than that in the control group [52.94% (18/34)] (χ2=5.368, P=0.021). Postoperative incision bleeding occurred in 4 cases of the trial group and 3 cases of the control group, and there was no significant difference in bleeding-related complications between the two groups (P=1.000). There was 1 case of venous thrombosis of the lower extremities in each group after operation, and there was no significant difference in the incidence between the two groups (P=1.000). Besides, no pulmonary embolism occurred in the two groups.ConclusionPerioperative use of tranexamic acid sequential rivaroxaban in elderly LIF patients can effectively reduce the amount of blood loss and the proportion of blood transfusion patients without increasing the risk of postoperative thrombosis.

  • Effect of enhanced recovery after surgery on postoperative function and pain in total hip arthroplasty patients with high comorbidity

    Objective To investigate the effects of enhanced recovery after surgery (ERAS) on postoperative function and pain in total hip arthroplasty (THA) patients with high comorbidity. Methods Patients with THA who were admitted between January 2020 and January 2022 were selected as the study objects, and a total of 223 patients with high comorbidity met the selection criteria. Patients were randomly divided into two groups using the random envelope method. During perioperative period, 112 cases in the ERAS group were treated according to the ERAS protocol and 111 cases in the control group with the traditional protocol. There was no significant difference in gender, age, body mass index, Charlson comorbidity index, preoperative diagnosis, the type and number of the comorbidities, preoperative visual analogue scale (VAS) score between the two groups (P>0.05). However, the Harris score of ERAS group was significantly lower than that of control group before operation (P<0.05). Preoperative and postoperative hospital stays were recorded. The VAS score was used to evaluate the pain before operation, at 1 day after operation, at the leaving bed time, at the day after discharge, and at 2 weeks after operation. Harris score was used to evaluate hip function before operation and at 2 weeks, 1 month, 3 months, 6 months, and 12 months after operation. The incidence of complications, 30-day readmission rate, mortality rate, and patient’s satisfaction were recorded. Results The length of preoperative hospital stay in ERAS group was significantly shorter than that in control group (P<0.05). But there was no significant difference in the length of postoperative hospital stay between groups (P>0.05). All patients in the two groups were followed up 12 months. The VAS score in the two groups after operation was lower than that before operation, and showed a gradually trend with the extension of time, with significant differences between different time points (P<0.05). VAS scores of ERAS group were significantly lower than those of control group at different time points after operation (P<0.05). The postoperative Harris scores in both groups were higher than those before operation, and showed a gradually increasing trend with the extension of time, with significant differences between different time points (P<0.05). Harris scores of ERAS group at 2 weeks, 1 month, and 3 months after operation were significantly higher than those of control group (P<0.05). Complications occurred in 2 cases (1.79%) of the ERAS group and 6 cases (5.41%) of the control group, with no significant difference in incidence (P>0.05). In the control group, 1 case was readmitted within 30 days after operation, and 1 case died of severe pneumonia within 1 year of follow-up. There was no readmission or death in ERAS group, and there was no significant difference in the above indexes between the two groups (P>0.05). At last follow-up, the satisfaction rate of patients in ERAS group was slightly higher than that in control group, but the difference was not significant (P>0.05). Conclusion For THA patients with high comorbidity, ERAS protocol can shorten preoperative waiting time, better reduce pain, and improve hip function.
