2. | Impact of different degrees of computed tomography-based oversizing on clinical outcomes after transcatheter aortic valve implantation using the Portico system Serkan Aslan, Ali Rıza Demir, Fatih Uzun, Ömer Çelik, Ali Kemal Kalkan, Mehmet Ertürk doi: 10.5543/tkda.2021.32582 Pages 180 - 190 OBJECTIVE: The study aimed to evaluate the influence of different degrees of multidetector computed tomography (MDCT)–based perimeter oversizing on incidence and severity of paravalvular aortic regurgitation (PAR) and conduction disturbances (CD) for the Portico device. METHODS: We retrospectively analyzed 63 patients who underwent transcatheter aortic implantation (TAVI) in our center from March 2017 to June 2019. Patients were divided into two groups (group I, below %13.9; group II, above 13.9%) based on the degree of oversizing. Oversizing was calculated as (Device nominal perimeter / MDCT-derived annular perimeter - 1) * 100. Procedural and clinical data were evaluated by VARC-2 definitions. RESULTS: Mild or greater PAR was present in 76.4% of patients in group I and 34.4% of patients in group II (P = 0.009). The rate of CD tended to be lower in the patient's group I (P = 0.034). A cutoff value of 13.9% was identified as having the best predictive value for mild or greater PAR. On multivariate analysis, a lower percentage of oversizing (odds ratio 6.38; %95 confidence interval 2.00 - 20.33; P = 0.002) emerged as the most powerful independent predictor of PAR, whereas the implantation depth and severe oversizing were independent predictors of CD (P = 0.003 and P = 0.029, respectively). We demonstrated that the optimal acceptable perimeter-based oversizing range appears to be between 10 - 15%. CONCLUSION: Perimeter-based oversizing by MDCT inversely correlated with PAR after TAVI for Portico device, and its preoperative evaluation could help in predicting PAR and CD. |
3. | Predictors of long-term mortality in acute ST-elevation myocardial infarction patients undergoing emergent coronary artery bypass graft surgery Begüm Uygur, Ömer Çelik, Ali Rıza Demir, Gökhan Demirci, Taner İyigün, Anıl Şahin, Ömer Taşbulak, Yalçın Avcı, Mehmet Ertürk PMID: 33847268 doi: 10.5543/tkda.2021.79059 Pages 191 - 197 Objective: Coronary artery bypass graft (CABG) surgery as a primary treatment for acute ST-elevation myocardial infarction (STEMI) is still debated. This study aimed to evaluate the predictors of long-term mortality in STEMI patients undergoing emergent CABG. To the best of our knowledge, this is the first study to evaluate the long-term mortality predictors in patients with STEMI revascularized by primary CABG. Methods: This retrospective study included 88 consecutive patients with STEMI, who did not qualify for primary percutaneous intervention and required emergent CABG between 2010 and 2017. The study population was divided into the following 2 groups: survivors and nonsurvivors. The 2 groups were compared in terms of demographics, preoperative, intraoperative, and postoperative characteristics. Results: 23 of the 88 patients, died during the median 92.8 (69.0-105.1) months of follow-up. Data were evaluated with univariate and multivariate analyses. Killip class (p<0.001) was found to be an independent predictor of long-term all-cause mortality in patients with STEMI revascularized by CABG, and mortality rates increased significantly as Killip class increased (log-rank test, p<0.001). Moreover, age (p=0.044) was found to be an independent predictor of long-term mortality. Left ventricular ejection fraction, glomerular filtration rate, glucose levels, and left anterior descending artery to the left internal mammary artery graft usage (p=0.001, p=0.009, p<0.001, and p=0.039, respectively) were significantly associated with long-term all-cause mortality for our study population. Conclusion: Killip class was found to be an independent predictor of long-term all-cause mortality in patients with STEMI who underwent emergent CABG. The patients’ admission status may give valuable information about long-term mortality. |
4. | Hyperkalemia in chronic heart failure with renal dysfunction or diabetes mellitus: Results from the TREAT HF study Selda Murat, Hakkı Kaya, Yüksel Çavuşoğlu, Mehmet Birhan Yılmaz doi: 10.5543/tkda.2021.58675 Pages 198 - 205 Objective: Chronic kidney disease (CKD) and diabetes mellitus (DM) are common comorbidities in heart failure (HF). Patients with HF are at a high risk of hyperkalemia, and are therefore undertreated with respect to disease-modifying therapies. The Turkish Research Team-Heart Failure (TREAT HF) data were analyzed for the evaluation of hyperkalemia in real-life clinical practice in HF patients with CKD or DM. Methods: The TREAT HF is a multicenter, national, observational registry. In this study, potassium levels of 1028 patients with HF were analyzed. Hyperkalemia is defined as blood potassium levels >5 mEq/L and evaluated based on the CKD, DM, HF medications, and New York Heart Association (NYHA) classes. Results: Overall, 14.3% of patients (n=147) were found to have hyperkalemia. Hyperkalemia was more prevalent in patients with estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 than those with eGFR ≥60 mL/min/1.73 m2 (17.7% and 12%, respectively, p=0.010). Hyperkalemia was present in 10.9% (n=23) of patients with stage 1, 12.6% (n=50) with stage 2, 17.0% (n=52) with stage 3, and 19.5% (n=22) with stage 4-5 CKD. Hyperkalemia was higher in patients with DM (20.5% vs 12.3%, p=0.001). Furthermore, hyperkalemia was much higher in patients with DM with eGFR <60 mL/min/1.73 m2 (25.2%). The rate of hyperkalemia increased across NYHA categories (NYHA-I: 9.8%, NYHA-II: 12.8%, NYHA-III: 14.4%, and NYHA-IV: 23.4%, p=0.030). In patients with stage 4-5 CKD who were receiving renin-angiotensin-aldosterone system (RAAS) inhibitor therapy, more patients had hyperkalemia than those not receiving RAAS inhibitor therapy (23.4% and 12.5%, respectively). Conclusion: In clinical practice, 14.3% of all patients with HF, 17.7% of all patients with CKD, and 20.5% of all patients with DM have hyperkalemia. The risk of hyperkalemia increases with advanced stages of CKD or NYHA and the risk is higher in patients receiving RAAS inhibitor therapy. |
5. | Comparison of clinical features and conventional echocardiographic characteristics of patients with heart failure with mid-range ejection fraction with and without interatrial block Mustafa Doğduş, İlhan Koyuncu PMID: 33350397 doi: 10.5543/tkda.2020.92345 Pages 206 - 213 Objective: Heart failure with mid-range ejection fraction (HFmrEF) has been proposed as a distinct heart failure (HF) phenotype. Interatrial block (IAB) is a conduction delay between the atria and is associated with cardiovascular disease. Although there are several studies examining the effect of IAB in patients with HF with reduced ejection fraction and HF with preserved ejection fraction, a literature review did not reveal any study investigating the clinical importance of the presence of IAB in patients with HFmrEF. Thus, the aim of this research was to evaluate clinical characteristics of HFmrEF with and without IAB. Methods: A total of 520 consecutive patients with HFmrEF in sinus rhythm who were examined at outpatient clinics were enrolled in the study (244 patients with IAB and 276 patients without IAB). Surface 12-lead standard electrocardiograms (ECGs) were recorded. Clinical characteristics, echocardiographic examination results, and laboratory values of the patients were recorded. Results: The mean age of the patients was 67.4±11.1 years, and 76.1% were male. The patients with IAB had more comorbidities, including hypertension, diabetes mellitus, and stroke/transient ischemic attack. A statistically significant, strong, positive linear correlation was observed between P-wave duration and age, systolic blood pressure, and left atrial volume index (r=0.718, p<0.001; r=0.704, p<0.001; and r=0.725, p<0.001, respectively). Conclusion: To the best of our knowledge, the present study is the first to evaluate the clinical relevance of IAB in HFmrEF. Adding this simple ECG marker to the clinical evaluation could add significantly to the management of HFmrEF. IAB can be used to identify high-risk HFmrEF patients, as well as to guide follow-up and appropriate treatment. |
6. | Correlation of vascular risk age with pulse wave velocity in young patients with low absolute cardiovascular risk Serkan Asil, Lale Tokgözoğlu, Hikmet Yorgun, Mevlana Giray Kabakçı, Kudret Aytemir, Necla Özer doi: 10.5543/tkda.2021.25068 Pages 214 - 222 Objective: The systematic coronary risk evaluation (SCORE) estimates the 10-year risk of fatal cardiovascular disease (CVD), and its application is recommended. The absolute risk of CVD, independent of risk factors, is relatively low in young individuals. Expressing the risk as their “risk age” may aid in understanding the risk. This study aimed to demonstrate a possible correlation between vascular risk age, SCORE risk value, and the level of subclinical atherosclerosis evaluated using a pulse wave velocity (PWV) device. Methods: This work was designed to be a cross-sectional study. The SCORE 10-year fatal CVD risk and vascular risk age were calculated for patients below the age of 50 years and without any previous diagnosis of atherosclerotic disease or equivalents. The PWV of each patient was measured non-invasively using a PWV device. Results: The study population included a total of 300 patients with a mean age of 35.1±9.5 years. The mean PWV and mean vascular age of the entire study population were 6.3±1.3 m/s and 44.3±5.5 years, respectively, and the median 10-year risk of fatal CVD score was 0.4 (0.04-2.74). There was a positive correlation between PWV and the 10-year risk of fatal CVD (r=0.613; P<0.001) and vascular risk age (r=0.684; P<0.001). Conclusion: Despite their young age and low to moderate 10-year risk of fatal CVD (<1%-5%) according to the SCORE chart, patients with a high vascular risk age were found to have high PWV values. These results show that calculations of vascular risk age might be used to assess the risk of fatal CVD in young patients and correlate with subclinical atherosclerosis. |
7. | Effect of atrial fibrillation on quality of life (AFEQT) questionnaire: A Turkish validity and reliability study Fatma Güneş, Sakine Boyraz doi: 10.5543/tkda.2021.41347 Pages 223 - 232 Objective: This study aimed to determine the validity and reliability of the atrial fibrillation effect on quality of life (AFEQT) questionnaire and evaluate the quality of life of patients with atrial fibrillation (AF). Methods: This was a methodological study that included 204 patients with AF over the age of 18 who participated voluntarily in the study. Data were collected using a structured questionnaire, the AFEQT questionnaire, and the University of Toronto atrial fibrillation severity scale (AFSS). The AFEQT questionnaire was translated into Turkish and presented to an expert panel, after which a pilot study was carried out with 20 patients for linguistic equivalence and cultural adaptation. The reliability of the AFEQT questionnaire was determined using Cronbach’s alpha and item-total correlation coefficient analyses. Results: The Cronbach’s alpha value was found to be 0.91, and the scale and subscale item-total correlation values ranged from 0.36 to 0.91. The validity of the AFEQT questionnaire was determined by construct, concurrent, and discriminant validity analyses. The factor loads of the AFEQT questionnaire ranged from 0.37 to 0.94 and the ratio was χ2/df=2.43 in the confirmatory factor analysis. A negative and highly significant relationship was found in concurrent validity between the AFEQT questionnaire and the AFSS. When AF risk factors were compared with the AFEQT questionnaire, it showed that AF-related risk factors negatively affected patients’ quality of life. The AFEQT questionnaire was suitable in terms of discriminant validity. Conclusion: The Turkish AFEQT questionnaire was found to be reliable and valid; therefore, we recommend its use to evaluate the quality of life of patients with AF. |

8. | Aortic floating thrombi with lower limb ischemia and renal infarct in COVID-19: A remote thromboembolic complication Cağdaş Topel, Ceren Yıldırım, Mustafa Ali Yavaş, Batuhan Yazıcı, Safa Göde doi: 10.5543/tkda.2021.12901 Pages 233 - 236 Summary– As the COVID-19 pandemic continues, its novel complications are being increasingly recognized, and new mechanisms of the disease are being unraveled. Aortic free-floating thrombus is exceptionally rare, and prompt diagnosis is vital to alleviate its detrimental end organ effects. We present a patient who was previously discharged owing to COVID-19 pneumonia, admitted with acute onset of lower limb pain, and was diagnosed with aortic free-floating thrombus ended up with embolic events. Clinicians should be aware of COVID-19-related thromboembolic complications, and close monitoring of patients with risk factors is vital for a timely and accurate diagnosis and management. |

9. | Transcatheter aortic valve implantation through the brachial artery Şakir Arslan, Nermin Bayar, Çağın Mustafa Üreyen, Erkan Köklü, Göksel Çağırcı PMID: 33847273 doi: 10.5543/tkda.2021.51892 Pages 237 - 241 Summary– Transcatheter aortic valve implantation (TAVI) has been increasingly used in patients with severe aortic stenosis. The femoral artery is the most commonly used entry site for TAVI; however, other entry sites were also reported as transapical, transaortic, transaxillary/subclavian, and transcarotid in patients with occlusive peripheral arterial disease. In this report, a case of TAVI procedure through the brachial artery is presented. |
10. | Unicuspid aortic valve with false aortic dissection appearance: A case report Barkın Kültürsay, Berhan Keskin, Seda Tanyeri, Ali Karagöz, Cihangir Kaymaz doi: 10.5543/tkda.2021.27793 Pages 242 - 244 Summary– Unicuspid aortic valve (UAV) is a rare congenital anomaly that usually presents with aortic stenosis or mixed stenosis and regurgitation early in life. Ascending aortic aneurysm and aortic dissection are important complications of UAVs. A 27-year-old man presented to the emergency department with a complaint of acute chest pain. Bedside transthoracic echocardiography (TTE) showed dilatation of ascending aorta (47 mm) and mild aortic regurgitation; computed tomography (CT) angiography revealed a suspicious dissection flap within ascending aorta. A cardiovascular surgeon, a radiologist, and a cardiologist were immediately consulted. TTE performed by the cardiologist revealed a unicuspid unicommissural aortic valve and dilated ascending aorta with no signs of dissection. Aortic dissection image on CT angiogram was interpreted by an experienced radiologist and the cardiovascular surgeon as superior pericardial recess and considered as a false-positive dissection image. Given the patient was pain-free, the CT image was considered false positive and as TTE clearly visualized the ascending aorta, the heart team decided that no further imaging is required. After excluding acute aortic syndrome, acute coronary syndrome, and other causes of acute chest pain, the patient was discharged with close follow-up. Diagnosis of aortic dissection is based on noninvasive imaging modalities, and CT is the first-line imaging choice in most emergency departments. Depending on a single imaging modality may cause false interpretations and lead to unnecessary surgical explorations. |
