This study aimed to assess the feasibility and surgical effect of AS repair versus transannular patch enlargement (TAPE) repair, especially in individuals with dysplastic pulmonary valves. Methods: This retrospective cohort study included 375 pediatric patients with a primary diagnosis of TOF in the Center for Pediatric Cardiac Surgery of Fuwai hospital from January 2014 to June 2017. Among them, 60 consecutive and nonselective patients underwent 1-stage repair of TOF with aggressive PVA-preserving strategies performed by a single surgeon were enrolled in AS cohort. In AS cohort, patients were divided into AS, PVA z-score ≥−2 group (33 patients) and AS, PVA z-score <−2 group (27 patients). During the same period, 315 patients underwent TAPE repair by other surgeons were enrolled as TAPE cohort, of these, 87 patients with PVA z-score ≥−2 were excluded. From the 228 patients in the TAPE group, 27 cases were selected as TAPE, PVA z-score <−2 group according to the propensity score and 1:1 ratio with AS, PVA z-score <−2 group. The primary outcome was a composite of reintervention, significant pulmonary regurgitation, and significant annular peak gradient (APG). Kaplan-Meier curve was plotted to show the survival rate of severe pulmonary regurgitation. Results: One death occurred after the TAPE operation in TAPE group, and 1 patient in the AS z ≥−2 group needed reintervention with a balloon. After a median follow-up of (30.3 ± 11.6) months, compared with AS z ≥−2 group, there was no difference in the technical performance score for severe pulmonary stenosis (APGs > 20 mmHg) in the AS z <−2 group. Compared with TAPE, AS repair was often accompanied by a postoperative APGs over 20 mmHg (P = 0.001). More patients underwent TAPE suffered from moderate or severe pulmonary regurgitation than those who received AS repair (20 (74.1%) vs. 7 (26.0%), P < 0.001). AS repair was associated with a shorter duration of mechanical ventilation (20 vs. 29 hours, P = 0.039), faster discharge from the intensive care unit (2.0 vs. 4.0 days, P = 0.022) and shorter postoperative hospitalization (8.0 vs. 11.0 days, P = 0.008) compared with TAPE. Conclusions: APG demonstrated an upward trend in the TAPE group and a downtrend in the AS group after discharge from hospital. AS repair had an acceptable surgical effect in TOF patients, even in those with a dysplastic PVA. A higher APG remained upon hospital discharge in dysplastic patients with AS, but a downward trend was observed over time.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"2 1","pages":"218 - 225"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43036822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although currently available therapies have improved outcomes, morbidity and mortality in patients with HF remain unacceptably high. Most guideline-recommended therapies for HF are indicated for patients with a reduced left ventricular ejection fraction (HFrEF). Until recently, treatment options that improved outcomes in patients with HF and preserved left ventricular ejection fraction or mildly reduced ejection fraction were limited. Over the past several years, however, several new drugs including angiotensin receptor neprilysin inhibitors (ARNIs), sodium glucose cotransporter 2 inhibitors (SGLT2 inhibitors), soluble guanylate cyclase stimulators, and a cardiac myotrope, omecamtiv mecarbil have all reported positive results in pivotal phase III clinical trials. Moreover, the results of these studies have provided evidence that both ARNIs and SGLT2 inhibitors can improve clinical outcomes in patients with HF across a broad spectrum of LVEF, not just in HFrEF. This article presents the rationale for the use of each of these 4 new classes of drugs, reviews the results from pivotal clinical trials showing their safety and efficacy, and provides a framework for how each drug has begun to be integrated into new HF management guidelines. Collectively, these new drugs provide hope for the millions of patients around the world who suffer from HF.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"2 1","pages":"231 - 240"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42758064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effect of GF on electrocardiogram (ECG) parameters and vulnerability to ventricular tachycardia/fibrillation (VT/VF) remains poorly characterized. This study aimed to assess the effect of GF on ECG parameters and induction of VT/VF in streptozotocin (STZ)-induced diabetic Sprague-Dawley rats. Methods: Male Sprague-Dawley rats were injected with STZ and randomly divided into 3 treatment groups: controlled STZ-induced diabetic rats (C-STZ) (n = 10); uncontrolled STZ-induced diabetic rats (U-STZ) (n = 10); and STZ-induced diabetic rats with glucose fluctuations (GF-STZ) (n = 10). After 12 weeks, baseline ECG recordings were taken and a VT/VF test was performed with the administration of caffeine and dobutamine. Hematoxylin & eosin and masson staining were used to evaluate pathological cardiac changes after intervention. Results: No significant difference in heart rate, RR interval, P wave (duration and height), PR segment, PR interval, QRS wave duration, and T wave height was observed among the 3 groups (P > 0.05). Compared with the C-STZ group, the U-STZ and GF-STZ groups both had a longer T wave duration ((62.41 ± 2.38) ms vs. (78.37 ± 4.64) ms and (96.06 ± 4.60) ms, P < 0.05), QT interval ((83.66 ± 2.31) ms vs. (101.75 ± 4.56) ms and (119.14 ± 4.88) ms, P < 0.05), and QTc interval ((77.45 ± 1.36) ms vs. (91.36 ± 3.49) ms and (104.55 ± 3.01) ms, P < 0.05), all of which were longest in the GF-STZ group (P < 0.05). Additionally, the GF-STZ group had the highest VT/VF occurrence and duration and the highest arrhythmia score. Conclusion: This study revealed GF can significantly prolong the QT interval, QTc interval, and T wave duration, as well as increase vulnerability to VT/VF in rats, which may be an important electrophysiological mechanism of GF-related ventricular arrhythmia.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"3 1","pages":"9 - 15"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41812682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Data from 760 consecutive patients in the Department of Cardiology, General Hospital of Northern Theater Command from August 2016 to December 2018 with drug-refractory symptomatic AF undergoing pulmonary vein isolation (PVI) using CB2 were assessed. Procedure-related safety and freedom from AF and atrial flutter/atria tachycardia through 3 years were determined. The risk factors related to atrial tachyarrhythmia recurrence were analyzed. Results: Acute PVI was achieved in 100% of the 760 patients. Radiofrequency application for additional focal ablation was needed in 11 (1.4%) patients and for 14 pulmonary veins (0.5%, 14/(760 × 4)) to achieve PVI. A total of 748 patients, including 539 with paroxysmal AF (PAF) and 209 with persistent AF (SAF) completed the follow-up, and only 12 (1.6%) patients were lost. The mean follow-up duration was (19 ± 8) months. The rate of major complications was 0.9%, including 0.8% of right phrenic nerve injury, which resolved before discharge. Freedom from all tachyarrhythmias was achieved in 75.0%, 69.4%, and 63.2% of patients with PAF, respectively, at 12-, 24-, and 36-month follow-up, and in 75.1%, 67.4%, and 60.9% for SAF, with no significant differences between the PAF and SAF groups. AF course and the rate of body weight gain were independent risk factors for recurrence at 12 months after ablation (P = 0.001 and P = 0.009, respectively). Conclusion: PVI using CB2 has a high acute success rate and good safety in the treatment of PAF and SAF. Long course of AF and weight gain after ablation were independent risk factors for recurrence.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"2 1","pages":"152 - 156"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42101641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A provisional stenting technique is currently recommended in most cases. This meta-analysis aimed to compare outcomes of different bifurcation PCI strategies, clarifying their scope of application. Methods: Randomized controlled trials comparing PCI strategies for coronary bifurcation lesions were systematically retrieved from PubMed, Cochrane, Web of Science, and EBSCO literature databases without limitations on published date or language. Major adverse cardiovascular events (MACEs) were stipulated as main outcomes. Secondary outcomes of interest were all-cause mortality, cardiovascular mortality, target lesion revascularization (TLR), target vessel revascularization, myocardial infarction (MI), and stent thrombosis. Both pooled analysis and sub-group analysis were performed. Results: Twenty-three randomized controlled trials with 6380 participants were included. Eighteen studies compared the provisional strategy with 2-stent approaches. No significant difference in MACEs (relative risk (RR), 1.16; 95% confidence interval (CI), 0.90–1.48; I2 = 62%) was found between 1-stent and 2-stent techniques. However, when SB lesion length was used as the separation condition, the 2-stent strategy was associated with fewer MACEs (RR, 1.87; 95% CI, 1.46–2.41; I2 = 70%), TLRs (RR, 2.13; 95% CI, 1.50–3.02; I2 = 59%), and MIs (RR, 2.17; 95% CI, 1.19–3.95; I2 = 52%) than the provisional strategy in those where SB lesions measured >10 mm long. Conclusions: In the current work, there was no significant difference between 1-stent and 2-stent techniques in terms of MACEs or secondary outcomes. However, 2-stent approaches have clinical advantages over the provisional strategy in bifurcation when the SB lesion length is >10 mm due to fewer cases of TLR and MI.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"2 1","pages":"157 - 173"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"61644823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intravascular imaging including intravascular ultrasound (IVUS) and optical coherence tomography (OCT) is paramount for the assessment of lesion characteristics and suboptimal stent results and to improve the outcome of percutaneous coronary intervention (PCI). After upgrading the use of IVUS and OCT by the American College of Cardiology/American Heart Association guidelines, their use has increased. Likewise, there has been significant improvement in image quality and the profile of system (ie, IVUS catheter size). The main indication for the use of IVUS includes: assessment of lesion characteristics, optimization of stent deployment, optimal stent expansion, exclusion of plaque burden >50%, and edge dissection. Intravascular imaging plays a significant role in the assessment and treatment of left main (LM) coronary artery stenosis and CBL. In particular, the use of intravascular imaging for alleviating mechanical issues during stenting and managing stent thrombosis has significantly increased. Overall, a compelling body of evidence has shown that the use of IVUS or OCT during PCI leads to optimal stenting results and mitigates the risk of adverse cardiac events. However, to date, the American College of Cardiology/American Heart Association Guidelines have assigned a Class IIb recommendation for IVUS or OCT, while the European Society of Cardiology Guidelines upgraded it to the Class IIa recommendation. This review summarized the role of IVUS and OCT for the assessment of stenosis and stent optimization in patients with CBL and LM stenosis. In addition, we discuss new insights into the role of IVUS- and OCT-guided stenting in patients with CBL and LM stenosis provided by the ongoing randomized trials.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"2 1","pages":"182 - 190"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44501283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
