Pacemaker lead ilişkili ciddi triküspit stenozu ve ciddi COVID-19 pnömoni hikayesi: Olgu sunumu
Tricuspid stenosis occurs after the implantation of a ventricular pacemaker lead and is a rare complication. An inflammatory response is stimulated when the pacemaker leads are passing through the tricuspid valve which leads to fibrosis in the long-term. In our case report, we aim to present a patient with asymptomatic multiple pacemaker lead- related tricuspid stenosis and with a history of severe COVID-19 pneumonia.Triküspit stenozu ventriküler pacemaker lead implantasyonu sonrası gelişen ve nadir görülen bir komplikasyondur. Pacemaker lead triküspit kapağı geçtiğinde inflamatuvar yanıt gelişir ve bu durum uzun dönemde fibroz ile sonuçlanır. Bu olgu sunumunun amacı, ağır geçirilmiş COVID-19 pnömonisi ve pacemaker lead ilişkili asemptomatik ciddi triküspit stenozu olan bir olguyu sunmaktır
The association of left atrial mechanics with left ventricular morphology in patients with hypertrophic cardiomyopathy: A cardiac magnetic resonance study
Purpose: Hypertrophic cardiomyopathy (HCM) is related with structural and pathologic changes in the left atrium (LA) and left ventricle (LV). The aim of this study was to explore the association between LA mechanics and LV charac-teristics in patients with HCM using cardiac magnetic resonance feature tracking (CMR-FT). Material and methods: A total of 76 patients with HCM and 26 healthy controls were included in the study. The pa-rameters including the extent of LV late gadolinium enhancement (LGE-%) and the LV early diastolic longitudinal strain rate (edLSR) were assessed for LV. LA conduit, booster, and reservoir functions were assessed by LA fractional volumes and strain analyses using CMR-FT. HCM patients were classified as HCM patients without LGE, with mild LGE-% (0% = 10%), and prominent LGE-% (10% < LGE-%).Results: HCM patients had worse LA functions compared with the controls (p < 0.05). The majority of LA functional indices were more impaired in HCM patients with regard to LGE. LA volumes were higher in HCM patients with prominent LGE-% compared with HCM patients with mild LGE-% (p < 0.05). However, only a minority of LA functional parameters differed between the 2 groups. LA strain parameters showed weak to modest correlations with LV LGE-% and LV edLSR.Conclusions: LV characteristics, to some extent, influence LA mechanics, but they might not be the only factor induc-ing LA dysfunction in patients with HCM
The diagnostic role of "acceleration time" measurement in patients with classical low flow low gradient aortic stenosis with reduced left ventricular ejection fraction
Purpose In our study, we aimed to assess the role of acceleration time (AT), ejection time (ET), and AT/ET ratio to distinguish between true and pseudo severe AS in patients with classical low flow-low gradient (LF-LG) aortic stenosis (AS) with reduced left ventricular ejection fraction (LVEF).
Methods Sixty-seven classical LF-LG AS with reduced LVEF patients who underwent dobutamine stress echocardiography (DSE) were included in the study. According to DSE results, all patients were divided into two groups; true AS and pseudo severe AS. Aortic valve calcium score was measured in patients with inconclusive DSE results. AT and other ejection dynamics (ET and AT/ET) were calculated by taking baseline echocardiographic records into account for all patients. The predictive power of AT and other ejection dynamics were evaluated to estimate true and pseudo severe AS.
Results According to DSE results, out of 67 patients, 44 (65.7%) was diagnosed as true severe AS. There was a statistically significant relation between baseline AT and true AS [adjusted OR 4.47 (95% CI 1.93-10.4), p = 0.001]. The best cutoff value of AT was measured as 100 msec according to the Youden index. This value had a sensitivity value of 77%, specificity value of 87%, positive predictive value of 92%, and a negative predictive value of 67%.
Conclusion The measurement of AT can predict the DSE outcome and can be used for diagnostic purposes to distinguish between true and pseudo severe AS in classical LF-LG AS patients with reduced LVEF
The role of three dimensional transesophageal echocardiography novel-score in the success of redo percutaneous balloon mitral valvuloplasty
Mitral valve commissure evaluation is known to be important in the success of percutaneous balloon mitral valvuloplasty (PBMV) and Wilkins score (WS) is used in clinical practice. In our study, we aimed to determine whether WS in redo PBMV is sufficient in the success of procedure and additionally we have evaluated a novel scoring system including three dimensional (3D) transesophageal echocardiography (TEE) of the mitral valve structure before redo PBMV in terms of success of the procedure. Fifty patients who underwent redo PBMV were included in the study. The patients were divided into two groups according to the success of the Redo PBMV procedure which was defined as post-procedural MVA ≥ 1.5 cm2 and post-procedural mitral regurgitation less than moderate by echocardiographic evaluation after PBMV. A novel score based on 3D TEE findings was created by analyzing the images recorded before Redo PBMV and by evaluating the mitral commissure and calcification. The role of traditional WS and novel score in the success of the procedure were investigated. In the study group, 36 patients (72%) had successful redo PBMV procedure. WS was 8 (IQR 7–9) and novel 3D TEE score was found 4 (IQR 3–4) in the whole study group. While no statistically significant relationship was found between WS and procedural success (p = 0.187), a statistically significant relationship was found between novel 3D TEE score and procedural success (p = 0.042). Specifically, the procedural successes rate was > 90% when novel 3D TEE score was < 4. The novel 3D TEE score might be an informative scoring system in the selection of suitable patients for successful redo PBMV, especially in patients who are considered for surgery due to the high WS
Kardiyovasküler İşlemlerde Görüntüleme
Doğum sırasındaki fizyolojik değişimlerle kapanması öngörülen foramen ovale erişkin populasyonun yaklaşık %75’inde tamamen kapanmış olarak izlenirken, %25’inde ise kapanmaz ve patent foramen ovale (PFO) olarak varlığını sürdürür.1 PFO, serebrovasküler olay dahil birçok patoloji (auralı migren, dalgıçlarda dekompresyon hastalığı vs.) ile ilişkilendirilmiştir. İskemik inmelerin %25’inde standart tanısal değerlendirmeye rağmen bir neden bulunamaz ve bu grup kriptojenik inme olarak adlandırılır. PFO ve kriptojenik inme arasındaki patofizyolojik ilişki paradoksal embolizm, PFO içerisinde meydana gelen trombüs, sol atriyal disfonksiyon ve atriyal aritmiler gibi nedenlere bağlı olabilir. Epidemiyolik veriler ve klinik gözlemsel çalışmalar, PFO kapatılmasıyla inme rekürrenslerinin azaldığını gösteren randomize kontrollü çalışmalar tarafından kuvvetle desteklenmektedir.2 PFO’nun tanısında ve perkütan tedavisinde çoklu görüntüleme yöntemleri önem arz etmektedir
Suboptimal use of non-vitamin K antagonist oral anticoagulants: Results from the RAMSES study
WOS: 000384041400052PubMed ID: 27583892This study aimed to investigate the potential misuse of novel oral anticoagulants (NOACs) and the physicians' adherence to current European guideline recommendations in real-world using a large dataset from Real-life Multicenter Survey Evaluating Stroke Prevention Strategies in Turkey (RAMSES Study).RAMSES study is a prospective, multicenter, nationwide registry (ClinicalTrials.gov identifier NCT02344901). In this subgroup analysis of RAMSES study, patients who were on NOACs were classified as appropriately treated (AT), undertreated (UT), and overtreated (OT) according to the European Society of Cardiology (ESC) guidelines. The independent predictors of UT and OT were determined by multivariate logistic regression.Of the 2086 eligible patients, 1247 (59.8%) received adequate treatment. However, off-label use was detected in 839 (40.2%) patients; 634 (30.4%) patients received UT and 205 (9.8%) received OT. Independent predictors of UT included >65 years of age, creatinine clearance 50mL/min, urban living, existing dabigatran treatment, and HAS-BLED score of <3, whereas that of OT were creatinine clearance <50mL/min, ongoing rivaroxaban treatment, and HAS-BLED score of 3.The suboptimal use of NOACs is common because of physicians' poor compliance to the guideline recommendations in patients with nonvalvular atrial fibrillation (NVAF). Older patients who were on dabigatran treatment with good renal functions and low risk of bleeding were at risk of UT, whereas patients who were on rivaroxaban treatment with renal impairment and high risk of bleeding were at risk of OT. Therefore, a greater emphasis should be given to prescribe the recommended dose for the specified patients
Guideline-adherent therapy for stroke prevention in atrial fibrillation in different health care settings: Results from ramses study
Objective No studies have been conducted in Turkey to compare the quality of stroke prevention therapies provided in different healthcare settings in patients with atrial fibrillation (AF). Therefore, we aimed to evaluate possible differences between secondary (SH) and tertiary hospital (TH) settings in the effectiveness of implementing AF treatment strategies. Methods Baseline characteristics of 6273 patients with non-valvular AF enrolled in the RAMSES (ReAl-life Multicentre Survey Evaluating Stroke Prevention Strategies in Turkey) study were compared. Results Of the study population, 3312 (52.8%) patients were treated in THs and 2961 (47.2%) patients were treated in SHs. Patients treated in the SH setting were older (70.8 ± 9.8 vs. 68.7 ± 11.4 years, p < 0.001), had a lower socioeconomic status, had a higher CHA2DS2VASc and HASBLED scores (3.4 ± 1.4 vs. 3.1 ± 1.7, p < 0.001 and 1.7 ± 1.0 vs. 1.6 ± 1.1, p < 0.001 respectively), and had more comorbidities than patients treated in THs. Inappropriate oral anticoagulant use was more prevalent in SHs than THs (31.4% vs. 25.6%, p < 0.001). When over- and undertreatment rates were compared among hospital types, overtreatment was more prevalent in THs (7.6% vs. 0.9%, p < 0.001) while undertreatment was more common in SHs (30.5% vs. 17.9%, p < 0.001). Conclusion This study demonstrates the marked disparity between patient groups with AF presenting at SHs and THs. The use of guideline-recommended therapy is not adequate in either type of centre, overtreatment was more prevalent in THs and undertreatment was more prevalent in SHs
