Objective:To evaluate the safety of leadless pacemaker implantation in super-elderly patients.Methods:Eleven patients with average age of 90 (86, 92) years who underwent leadless pacemaker implantation in the Department of Cardiology, Peking University People′s Hospital from March 2021 to May 2022 were included. The clinical data and implantation information were collected. The complications (cardiac tamponade, myocardial infarction, cerebral infarction, pulmonary embolism, pacemaker reinfection, femoral vein hematoma) and death of patients were documented at 24 h, 3 d, and 1, 3, 6 months after pacemaker implantation.Results:There were 9 males and 2 females with the body mass index of 21(19, 23)kg/m 2. The underlying diseases were hypertension, diabetes, coronary heart disease, chronic kidney disease, chronic obstructive pulmonary disease, previous cerebral infarction and moderate to severe tricuspid regurgitation in 9, 9, 9, 6, 4, 4, 4 patients, respectively. The left ventricular ejection fraction was 49% (45%, 52%), the hemoglobin concentration was 118 (114, 122)g/L, 4 patients were taking anticoagulant drugs, and 6 patients were taking antiplatelet drugs. Eight patients were newly implanted with a leadless pacemaker, 2 patients were implanted after removal the old ones, and 1 case was implanted at the same time as removal. The implantation time was 45(40, 47) minutes, the X-ray exposure time was 14 (13, 15) minutes, the release time was 1 (1, 2), the threshold value was 0.50(0.38, 0.75)V/0.24 ms, the impedance was 730 (700, 770) Ω, and the perceived R-wave amplitude 8.2(6.7, 12.8) mV. During the follow-up period of 8 (6, 10) months, no patient had pacemaker dysfunction; and the threshold, R wave sensing, and impedance were stable and maintained within the normal range. No cardiac tamponade, myocardial infarction, cerebral infarction, pulmonary embolism, pacemaker reinfection or death occurred perioperatively and during the follow-up period; 1 patient had hematoma after femoral vein puncture, which improved after compression treatment. Conclusion:This single-center and small-sample study shows that leadless pacemaker implantation is safe for super-elderly patients.

Intracardiac echocardiography Chinese expert consensus.

In recent years, percutaneous catheter interventions have continuously evolved, becoming an essential strategy for interventional diagnosis and treatment of many structural heart diseases and arrhythmias. Along with the increasing complexity of cardiac interventions comes ever more complex demands for intraoperative imaging. Intracardiac echocardiography (ICE) is well-suited for these requirements with real-time imaging, real-time monitoring for intraoperative complications, and a well-tolerated procedure. As a result, ICE is increasingly used many types of cardiac interventions. Given the lack of relevant guidelines at home and abroad and to promote and standardize the clinical applications of ICE, the members of this panel extensively evaluated relevant research findings, and they developed this consensus document after discussions and correlation with front-line clinical work experience, aiming to provide guidance for clinicians and to further improve interventional cardiovascular diagnosis and treatment procedures.

Imaging and pathogenic characteristics of thoracic ossification of the ligamentum flavum complicated with dural ossification / 中华骨科杂志

Objective To investigate the imaging characteristics and pathogenic manifestations of thoracic ossification of the ligamentum flavum complicated with dural ossification.Methods CT and MRI imaging data of 62 segments from 29 patients with thoracic ossification of the ligamentum flavum (TOLF) treated with "en bloc resection of lamina and ossified mass" were retrospectively analyzed.There were 19 males and 10 females,aged 54.9±10.25 years (36-77 years),16 segments in 11 cases with dural ossification (DO) and 46 segments in 18 cases without DO.The ossified mass shape,the relationship between ossified mas and dura mater on cross section of CT bone window and MRI T2WI,and the ossified mass occupational rate (OR) of the spinal canal were investigated.Pathologic features of TOLF-DO from 2 patients were analyzed by H&E staining.Results The shape of ossified mass was as followed,in 16 segments with DO,7 segments (43.8％) by CT and 2 segments (12.5％) by MRI showing ossification layer on the dural sac side of ligamentum flavum;1 segment (6.3％) by CT and 2 segments (12.5％) by MRI showing typical Tram track sign.The relationship between ossified mass and dura mater was that 7 segments (43.8％) by CT and 7 segments (43.8％) by MRI with "C" sign and 7 segments (43.8％) by CT and 8 segments (50.0％) by MRI with "V" sign.The ossified mass OR was 60.5％± 13.0％ in the group with DO and 42.2％± 12.3％ in the group without DO.There was a significant difference between the two groups (t=5.192,P＜0.001).Among the 16 segments with DO,the ossified mass OR of 7 segments with "C" sign was 68.8％± 12.8％ and that of the other 9 segments without "C" sign was 54.39％±9.9％.There was significant difference between the two groups (t=2.45,P=-0.028).Histological examination showed that there were two pathological phenomena in the dura tissue adjacent to ossified mass.The one,there were fibrocartilage,cartilage and osteogenesis in the dura mater.The other,the unossified dura mater fused with the ossified mass but with clear histological demarcation,while the dura mater on the ventral side of the ossified ligamentum flavum atrophies or disappeared.Conclusion The occurrence of dural sac ossification is associated with the ossification of ligamentum flavum beginning at the side of the dural sac and the persistent thickening of the ossified mass.The pathological manifestations of DO are ossification of dural tissue or fusion of dural with ligamentum flavum ossification.

Effect of local mild hypothermia on regional cerebral blood flow in patients with cerebral infarction assessed by 99mTc-ECD SPECT imaging / 实用医学杂志

Objective To investigate the frequency of lesions detection in patients with cerebral infarction (CI) with SPECT/CT. To investigate fluctuation of regional cerebral blood flow (rCBF) and its relationship with clinical symptoms. Methods Sixty-seven CI patients without cerebellar lesion were randomly selected. The rCBF in the regions of interest (ROI) was examined by SPECT/CT, which was collected from the frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, basal ganglia and cerebellum. The rCBF index was calculated. The association between fluctuation of rCBF index and clinical symptoms of patients was explored. Results There were 251 positive regions in all viewing regions , the total positive rate was 31.2%. The left side was 38.1%, while the right side was 24.4% (χ2=17.522,P 0.05). However, the average rCBF on the left parietal lobe was lower (P 0.05). rCBF≥0.7 is a clinical sign of abnormal ROI. Conclusion 30% of ROI of CI patients have lesions and the positive rate of the left side was higher. The biological rCBF values of all lobes were different. Therefore, rCBF index could be used to reflect whether the ROI is normal. rCBF≥0.7 could be used as a sign to quantitatively assess abnormal ROI in clinical practice.

Objective To study the relationship between ischemic stroke and gene polymorphism of an-giotensin-converting enzyme (ACE), apolipoprotein E (APOE) and methylene tetrahydrofolate reductase (MTHFR) among the population of Zhuang nationality in western Gui. Methods We directly sequenced ACE, APOE and MTHFR genes in 149 cases of ischemic stroke and 109 cases of normal people in western Gui. χ2 test was used to measure the relationship between gene polymorphism and ischemic stroke. Hardy-Weinberg genetic equilibrium test was used to evaluate the reliability of these data. Results In the ischemic stroke group, 62 cases, 22 cases and 65 cases carried II genetype, DD genetype and ID genetype in ACE. χ2 test showed no relationship between ACE gene polymorphism and ischemic stroke. In analysis of the polymorpism of APOE in the ischemic stroke and control group, no relationship between APOE gene polymorphism and ischemic stroke was found by χ2 test. MTFHR gene polymorphism was significantly related with ischemic stroke by χ2 test (P = 0.019). Conclusion Polymorphism of gene MTFHR but neither ACE nor APOE is significantly associated with ischemic stroke.

Expression and role of osteopontin and its receptors in ligmentum flavum cells derived from patients with ossification of ligamentum flavum / 中国组织工程研究

BACKGROUND:The exact pathogenesis of ossification of ligamentum flavum has not been elucidated yet. And osteopontin may be an important factor involved in the ossification of ligamentum flavum. OBJECTIVE:To clarify the expression and significance of osteopontin and its receptors, CD44 and integrin-β3, in ligamentum flavum cels between normal controls and patients with ossification of ligamentum flavum.METHODS:Ligamentum flavum tissues were obtained from normal adult controls and adult patients with ossification of ligamentum flavum (n=8 per group) who underwent thoracic/lumbar posterior decompression surgery. Ligmentum flavum cels were separated, cultured and identifiedin vitro, and osteopontin, CD44, integrin-β3 were stained using immunocytochemistry method and observed under inverted phase contrast microscope. And the mRNA expressions of osteopontin, CD44, integrin-β3 were measured by RT-PCR. RESULTS AND CONCLUSION: Immunocytochemistry results showed that the stronger positive staining for osteopontin, CD44, integrin-β3 was observed in the ossification of ligamentum flavum group than the control group (P < 0.01). The mRNA expressions of osteopontin, CD44 and integrin-β3 were also higher in the ossification of ligamentum flavum group than the control group (P < 0.05). These findings indicate that osteopontin and its receptors, CD44 and integrin-β3, in ligamentum flavum cels may play an important role in ossification of ligamentum flavum.

Presence of notched QRS on paced electrocardiographs as a predictor of poor response to cardiac resynchronization therapy / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Cardiac resynchronization therapy (CRT) on patients with advanced and refractory heart failure has made remarkable progress. Clinically, notched QRS (nQRS) is commonly seen on electrocardiographs (ECGs) with bundle branch block morphology and on paced ECGs after implantation of a CRT device, which may reflect the heterogeneity of ventricular myocardial depolarization and electrical activity. The aim of this study was to determine whether patients with more nQRS myocardial segments on paced ECGs had a worse response to CRT than patients with fewer nQRS myocardial segments.</p><p><b>METHODS</b>We prospectively enrolled 56 patients of CRT with chronic heart failure from People's Hospital affiliated to Peking University from January 2007 to October 2013. Based on nQRS segments on ECGs before CRT, we allocated them to two groups: fewer nQRS (<2) myocardial segments (lateral, inferior, anterior segments) group (F-nQRS, G1, n = 23) and more nQRS (≥2) myocardial segments group (M-nQRS, G2, n = 33). Then according to nQRS segments on ECGs after CRT, we divided them into two groups similarly: fewer nQRS (<2) myocardial segments group (G3, n = 24) and more nQRS (≥2) myocardial segments group (G4, n = 32). This study was approved by the ethics committee of People's Hospital.</p><p><b>RESULTS</b>At 6 months in the baseline-ECG group, there was a greater absolute increase in left ventricular ejection fraction (LVEF) in G2 than in G1 ((11.5±8.9)% vs. (5.5±10.4)%, P = 0.023), with the incidence of nonresponse lower in G2 than in G1 (9.1% vs. 39.1%, P = 0.018). In the paced-ECG group, the absolute increase in LVEF was less in G4 than in G3 ((6.4±8.8)% vs. (12.5±10.4)%, P = 0.024) and the incidence of nonresponse was higher in G4 than in G3 (31.3% vs. 8.3%, P = 0.039). Multivariate analysis showed that fewer nQRS (<2) myocardial segments on paced ECGs (odds ratio 13.920) was a predictor of positive response to CRT.</p><p><b>CONCLUSION</b>nQRS ≥2 myocardial segments (lateral, inferior, anterior) on paced ECGs may predict a poor response to CRT.</p>

The efficacy of permanent epicardial pacing in the treatment of pacing-dependent patients with cardiac device related endocarditis / 中华心血管病杂志

<p><b>OBJECTIVE</b>Permanent epicardial pacemaker is seldom used clinically and it is even less likely to be used for the treatment of seriously ill pacing-dependent patients with cardiac electronic device related endocarditis.</p><p><b>METHOD</b>We retrospectively analyzed the feasibility and efficacy of permanent epicardial pacing for the treatment of 3 pacing-dependent patients with cardiac electronic device related endocarditis, who were treated by removal of all pacemaker devices and reimplantation of permanent epicardial pacing system combined with antibiotics. The reason of using epicardial pacing system was as follows: uncontrolled sepsis (case 1); big vegetation on the electrode of pacemaker and tricuspid valve but not a candidate for open heart surgery because of high operative risk (case 2); occlusion of superior vena cava (case 3).</p><p><b>RESULTS</b>All 3 patients were cured with the treatment of extraction of infected pacing system, re-implanted permanent epicardial pacing system and antibiotics. The permanent epicardial pacemaker worked well during the 2-12 months follow-up period and there was no recurrence of infection.</p><p><b>CONCLUSIONS</b>Permanent epicardial pacing is useful and efficient in treatment of seriously ill and high risk pacing-dependent patients with cardiac device related endocarditis.</p>

Reuse of infected cardiac rhythm management devices in the same individual.

PURPOSE: Infected device explantation is increasingly necessary given the rapid growth in cardiac rhythm management device (CRMD) implantation in China. However, some patients with CRMD infection are unlikely to be capable of paying for a new device. Reassuringly, evidence suggests that reuse of cardiac devices can be safe and feasible. In this study, we evaluated whether explanted cardiac devices, due to infection, can be reimplanted safely within the same individuals. METHODS: All patients with CRMD infection between 2007 and 2010 were entered into a computer database. From these, patients that had need for CRMD implantation and reimplantation of their infected device were analyzed for safety and complications. RESULTS: Sixty patients had CRMD implantation after the infected device removal, and 44 (73.3 %) patients underwent procedures for reimplantation of their infected device. The mean age of the patients was 64.8 ± 16.5 years, and 32 (72.7 %) were male. Indications for device explantation were: pocket infection (86.6 %) and endocarditis (11.4 %). The average follow-up was 20.4 ± 9.0 months. Endocarditis recurred in one (2.3 %) patient with Brugada syndrome at 17 months after reimplantation of a refurbished implantable cardioverter-defibrillator. There were three deaths during the follow-up period secondary to myocardial infarction and cerebral vascular accident. No early battery depletion or device malfunction was identified during follow-up. CONCLUSIONS: Our data emphasize that reimplantation of explanted CRMDs, due to infection, within the same individual is feasible, safe, and effective. Reuse of explanted CRMDs is an alternative choice for people in developing countries.
