Background
Atrial fibrillation (AF) is a frequent manifestation of hypertrophic cardiomyopathy (HCM) and it is associated with increased risk for thromboembolic events and worsening of heart failure. AF is usually refractory to antiarrhythmic drugs in cases with HCM and catheter ablation may be useful in such patients.
Purpose
We aimed to evaluate outcomes of both cryoballoon and radiofrequency (RF) AF catheter ablation in patients with HCM.
Methods
All of the patients with HCM who underwent AF catheter ablation between January 2014 and January 2022 were screened and patients with available follow-up datas were included.
Results
A total of 44 patients were enrolled. Mean age was 54.2±12.6 years and 45.5% of the patients were female. RF ablation was performed in 23 cases and remaining patients underwent cryoablation. Median follow-up was 42.5 (4-94) months. Baseline characteristics were listed in Table-1. Only pulmonary vein isolation was performed in 25 (56.8 %) patients while additional ablation procedures including left atrial appendage isolation and linear ablation were required in other cases. Periprocedural complications occured in 6 cases. Atrial tachycardia recurrence developed in half of patients and mortality occured in 2 (4.5 %) cases during follow-up (Table-2).
Six months recurrence free survival (RFS) rate was 90.9% and 1 year RFS was 86.1% however RFS rate reduced to 58.2 after 3 years follow-up. Atrial tachycardia recurrence rates, complication and mortality rates were similar between the patients who underwent cryoablation and RF ablation. Changes in NYHA class and BNP levels were not significant during follow-up, however EHRA class was distinctly improved (II vs. I; p<0.001).
Conclusion
Although long term outcomes of AF catheter ablation is not satisfactory; it is effective in short term rhythm control with reasonable complication rates. Recurrence rates are similar between RF and cryoablation.

Background
Radiofrequency (RF) and cryoballoon (CB) ablation are the most commonly performed methods for catheter ablation in patients with atrial fibrillation (AF). However, data regarding AF ablation in patients with reduced left ventricular ejection fraction (LVEF) is scarce.
Purpose
We aimed to compare the safety and efficacy of RF and CB AF ablation in heart failure (HF) patients with LVEF <50%.
Methods
HF patients whose LVEF < 50% were included in this retrospective study. Transthoracic echocardiography (TTE) was performed to evaluate LVEF by using Modified Simpson method before and after the procedure. Atrial tachyarrhythmia (ATa) recurrence was defined as detection of AF, atrial flutter, or atrial tachycardia (≥ 30 s) after a 3-month blanking period.
Results
Eighty-nine (n = 42 CB and n = 47 RF) HF patients were enrolled and baseline characteristics were listed in Table-1. There was no significant difference in AF recurrence rate between the groups [16 (38.1 %) in CB and 12 (25.5 %) in RF, respectively, P = 0.296] during the follow up of median 16.5 (10.25-24) and 11 (9-17) months (Figure-1). There was significant increase in LVEF (39.52 ± 7.77 vs. 46.30 ± 10.95, P < 0.001) and decrease in brain natriuretic peptide (BNP) [230 (10-1653.10) vs. 163 (10-1653.10), P = 0.003] levels after ablation. The changes in LVEF (P = 0.370) and BNP (P = 0.772) were similar between the CB and RF ablation groups.
Conclusion
Our findings demonstrated that AF ablation using either CB or RF was associated with an improvement in LVEF and neurohormonal profile in AF patients with reduced LVEF.

Background/Introduction
Hypertension is an important and common reason of cardiovascular diseases. Hypertension can prevent, delay and/or manage with lifestyle modifications like regular physical activity participiation, stress management. During COVID-19 pandemic physical inactivity, increased stress and anxiety levels impair disease management of hypertensive individuals and becomes a serious risk factor for healthy individuals.
Purpose
We aimed to investigate and compare physical activity, anxiety and depression level of hypertensive and healthy individuals.
Methods
Forty hypertensive and forty healthy individuals were included in the study (Mean age: 51,15±6,96 years and 49,75±8,41 years, respectively). Patients informed about the study and invited during their cardiology visit and called by a physiotherapist in lockdown periods. In phone call, working status, quarantina compliance, sociodemographic status were asked. Physical activity levels were assessed with International Physical Activity Questionnnaire-Long Version (IPAQ), anxiety and depression levels were examined with Hospital Anxiety and Depression Scale (HAD). Patients categorized as inactive, minimally active and active according to METs results of IPAQ and classified as increased depression and/or anxiety according to HAD results.
Results
Working status, quarantina compliance and gender were similar between groups (p>0,05). Anxiety and depression scores were similar but number of people who had increased depression were higher in hypertensive group. Considering physical activity, transport, vigorous domestic activities, leisure time vigorous activities and total physical activity levels were statistically different between groups (p<0,01, p=0,002, p=0,002,respectively) and hypertensive individuals were less active. When we compared physical activity categorization, in hypertensive group 12,5% were active, 47,5% were minimally active and 40% were sedentary and in healthy group 32,5% were active, 50% were minimally active and 17,5% were sedentary and physical activity status were statistically significant (p=0,029).
Conclusion(s)
According to our results, hypertensives were more inactive and deprressed than healthy controls. Quarantine periods become very inactive periods for all populations but this is very crucial for especially risky populations. To prevent upcoming cardiovascular diseases and complications of hypertension physical activity and psychosocial support can implement by healthcare providers.

Introduction and Background
6 Minute Stepper Test (6MST) is a valid, reliable and practical field test that evaluates exercise capacity in chronic conditions. There is a need for evaluating the validity and reliability of 6MST in for using evaluation during cardiac rehabilitation.
Purpose
The aim of this study was to evaluate the validity and reliability of 6MST test in patients with systemic hypertension.
Methods
Forty hypertensive individuals (mean age: 47.55 ± 6.55 years, female/male: 24/16) were included in the study. Demographic and clinical characteristics of patients were recorded and echocardiography was conducted. Functional exercise capacity was evaluated with 6MST and step number during 6MST was recorded. Exercise capacity was tested with the six minutes walk test (6MWT) and used for validity.
Results
Clinical and demographic status of patients were presented in Table-1. According to the test-retest ICC (Intraclass correlation coefficient) analysis for the reliability of 6MST test in hypertensive patients; 6MST test score has very good reliability for single measurements (ICC value = 0.896, p <0.001) and mean measurements (ICC value = 0.945, p <0.001). According to the results of pearson correlation analysis to evaluate the criterion validity of 6MST test; 6MST test score showed a high relationship with 6MWT distance as the criterion test (r = 0.689, p<0.001) in patients with systemic hypertension.
Conclusions
6MST can be used as a valid and reliable test to evaluate exercise capacity in patients with hypertension. Because it is practical, tolerable and safe so it may be a new valid field test in cardiac rehabilitation.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TAVI) has become the standard of care treatment in patients with severe aortic stenosis who carry intermediate or high risk for surgical aortic valve replacement. Mitral annular calcification (MAC) is frequently seen in patients with aortic stenosis and it is associated with increased cardiovascular morbidity and mortality. It is reported that MAC is an independent predictor of all cause mortality after TAVI.
Aim
The aim of this study is to both evaluate the relationship between mitral annular calcification and TAVI related complications and mortality; and to define the predictors of both all cause mortality and permanent pacemaker implantation after TAVI.
Methods
All of the patients who underwent TAVI procedure due to severe aortic stenosis between 01.01.2020 and 01.06.2020 in our University Hospital were screened and patients fullfilling including criterias were enrolled. Patients' baseline demographic datas, laboratory, echocardiography and TAVI procedure related parameters were recorded. Outcomes are identified as follows; association between mitral annular calcification and TAVI related complications, establishment of the predictors of all cause mortality and permanent pacemaker implantation, definition of the in-hospital and all cause mortality rates.
Results
A total of 245 patients including 98 males (40%) and 147 females (60%) were enrolled in the study. The mean age of the population was 76,3±8,3 years. The mean left ventricular ejection fraction was % 54,8±11,4; aortic valve area was 0,74±0,14 cm2 and mean aortic transvalvular gradient was 47,0±14,3 mmHg. MAC was detected in 148 (% 60,4) patients (Table 1). In-hospital mortality was occurred in 14 (5,7%) cases. Permanent pacemaker implantation was performed in %17,8 (n=42) patients and all cause mortality was developed in 89 (36,3%) cases during the median 23,1 (11,6–44,3) months follow-up. Pericardial effusion (26,4% vs 12,4%; p=0,013) and contrast induced nephropathy (21,6% vs 7,2%; p=0,005) were developed more frequently in patients with MAC than without MAC (Table-2). Only the presence of MAC extending to left ventricular outflow tract was detected to be independent predictor of permanent pacemaker implantation requirement (HR: 3,32; p=0,002). All cause mortality predictors were established as; use of renin-angiotensin-aldosterone system blockers (HR: p=0,012), level of hemoglobin (HR: 0,79; p=0,006), severe mitral annular calcification (HR: 1,94; p=0,024) and atrial fibrillation development after TAVI (HR: 2,39; p=0,002). There was not any correlation between aortic valve area and MAC vloume (r=0,03; p=0,689), MAC Hounsfield Unit (r=−0,007; p=0,934) and MAC Agatston score (r=−0,08; p=0,290).
Discussion
MAC is associated with all cause mortality after TAVI and MAC extending to left ventricular outflow tract is an independent predictor of permanent pacemaker implantation requirement.

Abstract
Abstract
Background/Introduction
Covid-19 disease, which affects more than 128 million people worldwide, has caused changes in lifestyle and physical activity habits in patients with cardiovascular disease due to lockdown restrictions. During the pandemic period, patients with chronic diseases (also patients with comorbidities) cannot participate in physical activity and exercise programs due to social isolation.
Purpose
The aim of our study is to investigate the relationship between the comorbidities of heart rhythm disorder patients and their physical activity levels and kinesophobia in the Covid-19 pandemic.
Methods
105 individuals (54 healthy adults, 51 patients with heart rhythm disorders) were included in this study.
Physical Activity Level: Physical activity level was evaluated using the International Physical Activity Questionnaire-Short Form (IPAQ-SF).
Fear of Movement: Fear of movement was evaluated using the Tampa Scale of Kinesiophobia for Heart.
The Comorbid Conditions: The comorbid conditions of the patients were evaluated by the Charlson comorbidity index.
Results
Table 1. In patients with heart rhythm disorders, there was a negative, moderate correlation between the Charlson comorbidity index and the number of daily steps (r=−402, p=0.03), while a positive, moderate relationship with the Charlson comorbidity index and Tampa score (r=391, p=0.05) has been found.
Conclusion
While the Charlson comorbidity index value and Tampa Score were higher in patients with heart rhythm disorders than in the control group, the number of inactive patients among the subgroups of the IPAQ-SF scale was higher than the control group.
While heart rhythm disorders patients with more comorbidities are more prone to develop kinesiophobia, the number of daily steps decreases in the same direction.
Management of comorbidities of patients with heart rhythm disorders can be provided by physical activity counseling to these people.

Backround
Atrial fibrillation (AF) is associated with poor outcomes after transcatheter aortic valve implantation (TAVI).
Purpose
This study aimed to investigate whether prolonged total atrial conduction time (PA-TDI) predicts the development of AF in TAVI-treated patients.
Methods
A total of 307 TAVI-treated patients were enrolled. PA-TDI was defined as the duration from P wave onset on electrocardiography to peak A′ wave on tissue Doppler imaging echocardiography.
Results
The study was conducted with 263 patients because 44 patients had pre-existing AF. Of 263, 47 (17.8%) had new-onset AF after TAVI procedure. Age, mortality and the frequency of PM implantation were higher in the AF group. LVEDD, LVEF, aortic gradients, and AVA were similar between AF and sinus rhythm groups; however, LVESD, LA diameter, and PA-TDI duration were increased in the AF group. In Kaplan–Meier analysis (Panel A), there was an increase in risk of AF with each incremental percentile of the PA-TDI duration. In multivariate analysis, age (p = 0.005) and PA-TDI duration (p = 0.002) were found to be independent risk factors for the development of AF after TAVI. AUC was 0.630 (p = 0.005), and the sensitivity and specificity were 70% and 51% respectively at a cut-off point of 123.5 ms for PA-TDI duration (Panel B).
Conclusion
In patients treated with TAVI, post-procedural new-onset AF may lead to significant risk for morbidity and mortality. PA-TDI duration can be used for the detection of the patients with high risk of AF development.

Abstract
Abstract
Background
Electrical storm (ES) is defined as 3 or more episodes of sustained ventricular tachycardia (VT) within 24 hours and related with high mortality rates. Catheter ablation is an effective treatment option in patiens with ES.
Purpose
We aimed to evaluate outcomes of VT catheter ablation in patients with ES.
Methods
All patients who underwent catheter ablation due to VT ablation between June 2014 and November 2018 were screened and outcomes of patients who admitted with ES were evaluated.
Results
A total of 128 patients were included. 52 (40.6%) patients were admitted with ES. Mean age of the patients with ES was 68 ± 10,5 years and 48(92,3) patients were male. Median follow up was 22.5 (8-46) months. Baseline characteristics were listed in Table- 1.Multivariate regression analysis revealed that hemoglobin level (HR:0.76, CI:0,61-0,94, p = 0.011 ) and antiarrhythmic drug use (HR:0.25, CI:0,10-0.62, p = 0.003) were predictors of ES development. Recurrence rates and number of re-do ablation procedures were significantly higher in patients with ES (Table-1). Cardiovascular and all cause mortality rates were also significantly higher in patients with ES (Table-1).
Conclusion
Despite catheter ablation is an effective treatment in patients with ES; presence of ES is related with increased mortality and recurrence rates after ablation.

A total of 493 patients were enrolled. Mean age was 59.6 ± 11.8 years and 253 (51.3 %) patients were female. Median follow up time was 28 (6-59) months. Recurrence occured in 61 (12.4%) patients. Diabetes was present in 78 (16%) cases. Mean HbA1c value of the diabetic patients was 6.79 ± 1.02 %. 50 (64.1 %) patients was under treatment with only oral antidiabetics while others were using insulin. Diabetic group was older (p < 0.001) and hypertension prevalance was significantly higher in diabetics(p < 0.001). Complication and recurrence rates were similar between the two groups (Table-1). Subgroup analysis revealed that there was not significant difference by AF recurrence between not only patients treated with OAD alone and treated with insulin but also patients with HbA1c value <7 and HbA1c value ≥7 (p = 0.064).
Conclusion
Recurrence and complication rates were similar between diabetic and non-diabetic patients. Despite neuropathy is a well known manifestation of diabetes; phrenic nerve damage rate is similar in diabetic patients with non-diabetic counterparts.

Abstract
Abstract
Background
Ablation of ventricular tachycardia (VT) is an effective and safe treatment option in symptomatic patients under antiarrhythmic drugs or patients with frequent ICD therapies.
Purpose
We aimed to evaluate outcomes of VT catheter ablation in patients with ischemic VT.
Methods
All of the patients who underwent VT catheter ablation between June 2014 and November 2018 were included.
Results
128 patients (120 male, 8 female) were included and mean age was 65 ± 10 years. Mean ejection fraction was 28.6 ± 8.2 %. Baseline characteristics were listed in Table-1. Mean follow-up was 22.3 ± 6.4 months. 52 (46.6 %) patients were admitted with electrical storm. Acute success rate was 96.6%. Complications including transient ischemic attack, deep venous thrombosis, pericardial effusion and inguinal hematoma were developed in 6 patients. Recurrence of VT was occured in 44 (34.4 %) patients and the presence of PCI history and admission with electrical storm were predictors of recurrence. All cause mortality was occured in 39 patients and predictors of all cause mortality was detected as follows; diabetes, NYHA stage >2, lower levels of EF and higher BNP levels. Cardiovascular mortality was developed in 28 patients and predictors were defined as, lower levels of EF, higher BNP levels and number of shock after index ablation. VT recurrence was not found to be related with both cardiovascular and all cause mortality.
Conclusion
VT ablation is a safe and effective option in patients with ischemic VT who are symptomatic despite optimal medical treatment. Admission with electrical storm and history of PCI were predictors of VT recurrence after ablation. Higher levels of BNP, lower EF values are related with both all cause and cardiovascular mortality.

Abstract
Abstract
Background
Cryoballoon (CB) ablation is a safe alternative to radiofrequency ablation in the treatment of atrial fibrillation (AF). However, phrenic nerve damage (PND) is a bothersome complication of the procedure.
Purpose
In this study, we aimed to establish the incidence of PND during CB and define the characteristics of affected patients.
Methods
In this retrospective analysis, all patients with AF that underwent CB ablation between 2013 and 2018 were included into the study. Characteristics and outcomes of patients complicated with PND were evaluated. PND was detected by palpation of diaphragma contractions or observation of reduced diaphragma motility by fluoroscopy during the procedure.
Results
Totally 653 patients were included in the study. PND was detected in 3.5% (23/653) of the patients. Median age of the patients with PNP was 56 (25–78) years and 10 patients (43.4%) were male. The most common ablation site related with PND was right superior pulmonary vein (RSPV) (18 patients, 78%). Transient PND was observed in 16 patients (69%) of the patients which resolved within 24 hours after the procedure. In the remaining 5 patients (21%) diaphragmatic contraction was recovered at the 6th month control visit. In 2 patients (10%), phrenic nerve paralysis was still present >1 year visit.
Table 1. Baseline characteristics of patients with PND Age (years), median (min–max) 56 (25–78) Gender, n (male %) 10 (43.4%) Hypertension, n (%) 9 (39.1%) LA (mm), (mean ± sd) 38.5±5.8 EF (%), (mean ± sd) 60.8±6.5 Structrual heart disease, n (%) 3 (0.13%) – HCMP 2 (0.087%) – DCMP 1 (0.043%) DCMP: Dilated cardiomyopathy; HCMP: Hypertrophic cardiomyopathy; EF: Ejection fraction; LA: Left atrium; PND: Phrenic nerve damage.
Conclusion
PND is not a rare complication of CB ablation despite all the preventive maneuvers during the procedure and technological developments. However, most of the PND recovered during the follow-up.

Abstract
Abstract
Background
Currently available second-generation cryoballoon (CB2) is accepted as an effective and safe tool for pulmonary vein isolation (PVI). Although much more data exists about 1-year outcomes of CB2 ablation, data on long-term outcomes are scarce. Objective: We aimed to assess the long-term outcomes of PVI using CB2 in a large-scale symptomatic AF population at our tertiary referral center.
Methods
In this non-randomized prospective observational study, a total of 486 patients with paroxysmal (71%) or persistent (29%) AF who underwent index PVI using CB2 at our hospital between January 2013 and June 2017 were enrolled. Atrial tachyarrhythmia (ATa) free survival was defined as absence of AF, atrial flutter or atrial tachycardia recurrence >30 s following 3-months blanking period. Predictors of recurrence were evaluated by univariate and multivariate Cox proportional hazards regression models.
Results
Acute procedural success rate was 99.8% (1898/1902 PVs). Mean procedural and fluoroscopy time were 64.9±9.2 and 12.1±2.6, respectively. At median 39 (IQR: 26–56) months follow-up, ATa free survival was 78.6% after a single procedure (280/345 [81.2%] for paroxysmal AF vs 102/141 [72.3%] for persistent AF, p=0.019) and 84.4% after a mean 1.48±0.42 ablations.Cox regression analysis showed that left atrium diameter, duration of AF history and early ATa recurrence were found as the independent predictors of late recurrence. PNP was observed in 17 (3.5%) patients.

Conclusions
Second-generation CB based PVI is effective to maintain sinus rhythm in a significant proportion of paroxysmal and early persistent AF patients with an acceptable complication rates at long-term follow-up.
