Predictive Value of the Modified Mehran Score for Contrast-Induced Nephropathy After Transcatheter Aortic Valve Implantation

Considering the increasing use of the transcatheter aortic valve implantation (TAVI) procedure, the relationship of contrast-induced nephropathy (CIN) with post-TAVI mortality has become important. The Mehran score was developed to detect the risk of CIN development after cardiac intervention. We aimed to compare the role of the modified Mehran score, which can be calculated pre-procedure, in predicting CIN development and compare it with the original Mehran score. We retrospectively collected data from TAVI procedures at our institution between December 2016 and June 2021; of 171 patients, 44 (25.7%) had CIN. We found no association between contrast media volume and CIN (387 ± 120 vs 418 ± 139 mL, P = .303). High and very high modified Mehran score and preoperative C-reactive protein (CRP) level were independent risk factors for CIN development after TAVI procedure. The area under curve (AUC) was .686 with 95% CI: .591-.780 and P < .001, and also, with a cut-off point of >7.5 points, there was 79.5% sensitivity and 63.0% specificity; otherwise, with a cut-off point of >9.5 points, there was 54.5% sensitivity and 71.7% specificity, for the modified Mehran score. The modified Mehran score comes into prominence compared with the original Mehran score since it can be calculated pre-procedure.

Evaluation of the Relationship between Cognitive Impairment and Atria Score Systems in Patients with Atrial Fibrillation

Background

Atrial fibrillation (AF) is the main arrhythmia associated with thromboembolic complications and cognitive impairment. In this study, we aimed to evaluate the relationship between cognitive impairment and different scoring systems developed for AF to improve the medical follow-up of cognitive impairment.

Methods

Between January 2019 and December 2020, 124 patients between the age of 30 and 80 years, diagnosed with AF for at least 5 years and complaining about memory impairment during cardiological follow-up, were included in the study. The patients were divided into two groups based on their cognitive status as assessed by the Mini-Mental State Examination group 1 consisted of 52 patients with cognitive impairment and group 2 comprised 72 patients without cognitive impairment.

Results

The ATRIA bleeding score had a positive moderate correlation (r = 0.454, P < 0.001), the ATRIA stroke score had a strong correlation (r = 0.738, P < 0.001), and the SAMe-TT2R2 score had a strong correlation (r = 0.688, P < 0.001) with cognitive impairment. However, CHADS2 and CHA2DS2VASc scores were not statistically correlated with cognitive impairment. According to the receiver operating characteristic (ROC) curve, the area under the curve (AUC) of the ATRIA bleeding score was 0.761 with a 95% confidence interval (CI) of 0.678-0.844 and P < 0.001; also, for the ATRIA stroke score, AUC was 0.930 with a 95% CI of 0.886-0.974 and P < 0.001. In addition, for the SAMe-TT2R2 score, AUC was 0.895 with a 95% CI of 0.838-0.952 and P < 0.001. In the pairwise comparison of AUC on ROC curves, the ATRIA stroke score and the SAMe-TT2R2 score were statistically similar (P = 0.324). ATRIA bleeding, ATRIA stroke, and SAMe-TT2R2 scores were greater than CHADS2 stroke score (P: 0.0004, P < 0.0001, and P < 0.0001, respectively), but CHA2DS2-VASc and CHADS2 stroke scores were statistically similar (P: 0.402).

Conclusion

Both ATRIA stroke and SAMe-TT2R2 scoring systems can provide a better correlation than CHADS2 and CHA2DS2-VASc scores in patients with AF to evaluate their cognitive status. These two scores can be more useful to monitor the patients with AF for medical follow-up of cognitive status.

Transjugular patent foramen ovale closure in a young patient with stroke caused by inferior vena cava thrombus: a different method with balloon anchor support to pulmonary vein

Patent foramen ovale closure is recommended for patients who are at risk for recurrent paradoxical embolism and cryptogenic stroke. The standard technique of patent foramen ovale closure is established from the femoral vein. However, alternative methods may be necessary for patent foramen ovale closure as in every interventional procedure. A 45-year-old female patient with an intramural giant uterine myoma had a history of recurrent deep vein thrombosis and stroke. A diffuse thrombus was detected in both iliac veins associated with inferior vena cava compression of the myoma. Also, a patent foramen ovale was revealed on echocardiography as a cause of embolic events. Hysterectomy was initially planned by gynaecology, but due to the possible risk of embolisation of inferior vena cava thrombus and stroke after removal of the compressive mass during hysterectomy, initial patent foramen ovale closure and then hysterectomy was scheduled in the Gynecology-Cardiology-Cardivascular Surgery council. Patent foramen ovale closure was performed via the right jugular vein approach. But because of the tight left atrial ostium of the patent foramen ovale, the catheter could not pass to the left atrium from the right atrium. With an anchor of a 5.0 × 15 mm coronary balloon over a 0.014-inch guidewire to the pulmonary vein, we were able to reach the left atrium. The patent foramen ovale was closed successfully, and the patient underwent a hysterectomy after closure without any embolic event. The patient was asymptomatic at 6 months of control.

Does MicroRNA Profile Differ in Early Onset Coronary Artery Disease?

OBJECTIVE

MicroRNAs have been explored as potential biomarkers for many pathological processes including coronary artery disease. In this study, we aimed to compare the circulating levels of selected atherosclerosis-associated miRNAs in patients with a history of early-onset coronary artery disease with that of age- and sex-matched healthy controls and older patients with late-onset coronary artery disease.

METHODS

Study population consisted of 30 patients with early onset coronary artery disease, 31 age- and sex-matched healthy controls, and 30 patients with late-onset coronary artery disease. Plasma levels of 13 microRNAs (endothelial cell-related miR-126, -92a/b; vascular smooth muscle cell-related miR-145; inflammation-related miR-16, -21, -125b, -146a/b, -147b, -150, -155; lipometabolism-related miR-27b, -122, -370) were evaluated by using real-time polymerase chain reaction.

RESULTS

In patients with early onset coronary artery disease, plasma expressions of the lipometabolism-related miR-27b, miR-122; inflammation-related miR-125b, miR-146a/b, miR-147b, miR-150, miR-155; and VSMC-related miR-145 were significantly downregulated and endothelial cell-related miR-126 was significantly upregulated compared to age- and sexmatched healthy controls. Circulating microRNA profile of patients with early onset coronary artery disease was also different from that of older patients with late-onset coronary artery disease. Plasma levels of miR-21, miR-27b, miR-122, miR-125b, miR-146b, miR-147b, and miR-155 were lower and plasma levels of miR-16 and miR-92a were higher in patients with early onset coronary artery disease compared to older patients with late-onset coronary artery disease.

CONCLUSION

MicroRNAs are promising biomarkers for early onset coronary artery disease.

Association between Intermountain Risk Score and long-term mortality with the transcatheter aortic valve implantation procedure

BACKGROUND

Since its first introduction, the spectrum and frequency of use of transcatheter aortic valve implantation (TAVI) have increased throughout the world. Therefore, it is crucial to determine which patients are at high mortality risk with TAVI. The Intermountain Risk Score (IMRS) is a score calculated from laboratory parameters. This study aimed to determine the long-term mortality of TAVI patients using the IMRS and to compare it with traditional scoring systems.

METHODS

The study included a total of 133 patients undergoing TAVI at our hospital from 2010 to 2019. Demographic data, co-morbid diseases, echocardiographic and laboratory parameters were collected retrospectively. The performance of IMRS was assessed as compared to the mortality determined in the overall patient population.

RESULTS

During the follow-up, 54.9% of patients (60 patients) (Group 1) survived; the mortality in Group 2 (60 patients) was 45.1%. The survival period had a mean of 1433 (±124) days. The mean IMRS was 1.67 (0.7) in Group 1 and 2.33 (0.72) in Group 2 (P <0.001). In multivariable analyses, only high risk of IMRS (hazard ratio [HR], 3.430; 95% confidence interval [CI], 1.537-7.653; P = 0.003) and EuroSCORE II (HR, 1.141; 95% CI, 1.011-1.288; P = 0.03) independently predicted long-term mortality.

CONCLUSIONS

From the evaluation of all laboratory and echocardiography parameters, long-term mortality (>30 days) following the TAVI procedure can be said to be higher in patients with a high IMRS. The data from this study can be considered of value in demonstrating the clinical significance of IMRS calculation before the TAVI procedure.

Spontaneous right coronary artery dissection in a patient with COVID-19 infection: A case report and review of the literature

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the global coronavirus disease 2019 (COVID-19) pandemic. Although the virus predominantly causes respiratory system infection, recent reports have shown that it is also associated with many cardiovascular complications. It has been reported that COVID-19 may cause myocarditis, type 1 and 2 acute myocardial infarction, and thrombotic complications.[1] Spontaneous coronary artery dissection (SCAD) is a rare form of coronary artery disease that has recently been associated with COVID-19 in a few case reports. The case reported here is of COVID-19 associated SCAD in a patient with no history of cardiovascular disease.

Late embolisation of an atrial septal occluder device in the abdominal aorta

Percutaneous closure of secundum atrial septal defect (sASD) - which is the most common in adult congenital heart disease - is considered to be the first treatment option but can involve early and late complications. We report on the late embolization of a device to the abdominal aorta, 12 months after successful percutaneous closure of sASD. A 63-year-old woman, who suffered from stomach ache, was found to have an ASD occluder device in her abdominal aorta. Although surgical intervention to remove the embolisation may be considered, medical follow-up and re-intervention of percutaneous closure may be feasible for inappropriate cases.

Decreased heart rate recovery may predict a high SYNTAX score in patients with stable coronary artery disease

An impaired heart rate recovery (HRR) has been associated with increased risk of cardiovascular events, cardiovascular, and all-cause mortality. However, the diagnostic ability of HRR for the presence and severity of coronary artery disease (CAD) has not been clearly elucidated. Our aim was to investigate the relationship between HRR and the SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery) score in patients with stable CAD (SCAD). A total of 406 patients with an abnormal treadmill exercise test and ≥50% coronary stenosis on coronary angiography were included. The HRR was calculated by subtracting the HR in the first minute of the recovery period from the maximum HR during exercise. The SYNTAX score ≥23 was accepted as high. Correlation of HRR with SYNTAX score and independent predictors of high SYNTAX score were determined. A high SYNTAX score was present in 172 (42%) patients. Mean HRR was lower in patients with a high SYNTAX score (9.8 ± 4.5 vs. 21.3 ± 9, p < 0.001). The SYNTAX score was negatively correlated with HRR (r: -0.580, p < 0.001). In multivariate logistic regression analysis, peripheral arterial disease (OR: 13.3; 95% CI: 3.120-34.520; p < 0.001), decreased HRR (OR: 0.780; 95% CI: 0.674-0.902; p = 0.001), peak systolic blood pressure (OR: 1.054; 95% CI: 1.023-1.087; p = 0.001), and peak HR (OR: 0.950; 95% CI: 0.923-0.977; p < 0.001) were found to be independent predictors of a high SYNTAX score. Our results showed that HRR is significantly correlated with the SYNTAX score, and a decreased HRR is an independent predictor of a high SYNTAX score in patients with SCAD.

The relationship between serum apelin levels and aortic dilatation in bicuspid aortic valve patients

OBJECTIVE

The bicuspid aortic valve (BAV) is the most common congenital heart disease. The process of aortic dilatation is not completely clear in patients with the BAV. Apelin is a peptide found at high levels in vascular endothelial cells which has a role in vascular regulation and cardiovascular function. The aim of this study was to determine the relationship between serum apelin levels and ascending aortic dilatation in adult patients with BAV.

DESIGN

This cross-sectional study included 62 patients with isolated BAV and to an age, gender, and body mass index-matched control group of 58 healthy volunteers with tricuspid aortic valve. Transesophageal echocardiography was performed on all patients to determine the type of BAV. Aortic diameters of the aortic root, sinus valsalva, sinotubular junction, and ascending aorta were evaluated with echocardiography. Patients with BAV were divided into two subgroups according to the aortic diameters, as the nondilated BAV group and the dilated BAV group. Serum apelin level was analyzed with ELISA method.

RESULTS

The serum apelin levels of the BAV patients were significantly lower than those of the control group (833.5, 25th-75th percentile (713.5-1745) pg/dL vs 1669 (936-2543) pg/dL; P = 0.006). In the subgroup analysis, serum apelin level was significantly different between the nondilated BAV group and the dilated BAV group [977 (790-2433) pg/dL vs 737 (693-870) pg/dL, P < 0.05] and between the dilated BAV group and the control group [737 (693-870) pg/dL vs 1669 (936-2543) pg/dL, P < 0.001]. In multivariate logistic regression analysis apelin [7.27 (95% CI: 1.73-30.42), P = 0.007] and age [1.05 (95% CI: 0.99-1.20), P = 0.049] were determined as independent predictors for ascending aortic dilatation.

CONCLUSION

Low serum apelin level was associated with dilatation of ascending aortic in BAV patients. However, apelin was not relevant to BAV without aortic dilatation.

Assessment of bicuspid aortic valve phenotypes and associated pathologies: A transesophageal echocardiographic study

OBJECTIVE

We investigated the frequency of different bicuspid aortic valve disease (BAV) phenotypes,the associated valvular pathologies, and the aortopathy phenotypes, using 2-dimensional (2D) transthoracic, 2D transesophageal echocardiography (TEE) and 3-dimensional (3D) TEE.

METHODS

A total of 154 patients with BAV were included. Five BAV phenotypes were detected. To better define valvular pathologies, binary classifications of BAV were used: BAV with antero-posterior commisural line (BAV-AP) and right-left commissural line (BAV-RL). Aortopathy phenotype was classified according to the involved tract(s).

RESULTS

Of the patients, 53.2% had type 1, 16.2% type 2, 15.6% type 3, 1.3% type 4, and 13.6% had type 5 BAV. The prevalence of BAV-AP and BAV-RL was 68.2% and 31.8%, respectively. No difference was detected with respect to aortic regurgitation between BAV-AP and BAV-RL (p=0.9), but the BAVRL group had an increased propensity to have a stenotic aortic valve (p=0.003). The indexed aortic diameter was larger in BAV-AP cases than BAV-RL at the sinus of Valsalva (p=0.008). In patients with dilatation of the root and tubular portion, a predominance of BAV-AP versus BAV-RL was observed (85% vs 15%). A markedly low prevalence of the root phenotype (3.2%) was observed. In 90.1% of the patients, 2D TEE was sufficient to classify BAV phenotypes; further 3D imaging was needed in 9.9% of the cases.

CONCLUSION

There may be racial differences in the frequency of valvular and aortopathy phenotypes in patients with BAV. BAV phenotypes differ with respect to aortic stenosis and aortopathy phenotypes. TEE may have good diagnostic utility in differentiating BAV phenotypes.

The relation between international normalized ratio and mortality in acute pulmonary embolism: A retrospective study

BACKGROUND

Acute pulmonary embolism (PE) is a serious clinical disease characterized by a high mortality rate. The aim of this study was to assess the prognostic value of international normalized ratio (INR) in acute PE patients not on anticoagulant therapy.

METHODS

The study included 244 hospitalized acute PE patients who were not receiving previous anticoagulant therapy. Based on their 30-day mortality, patients were categorized as survivors or non-survivors. INR was measured during the patients' admission, on the same day as the diagnosis of PE but before anticoagulation started.

RESULTS

Thirty-day mortality occurred in 39 patients (16%). INR was higher in non-survivors than in survivors (1.3±0.4 vs 1.1±0.3, P=.003). In multivariate analysis, INR (HR: 3.303, 95% CI: 1.210-9.016, P=.020) was independently associated with 30-day mortality from PE. Inclusion of INR in a model with simplified pulmonary embolism severity index (sPESI) score improved the area under the receiver operating characteristics (ROC) curve from 0.736 (95% CI: 0.659-0.814) to 0.775 (95% CI: 0.701-0.849) (P=.028). Also, the addition of INR to sPESI score enhanced the net reclassification improvement (NRI=8.8%, P<.001) and integrated discrimination improvement (IDI=0.043, P=.027).

CONCLUSION

Elevated INR may have prognostic value for 30-day mortality in acute PE patients not on anticoagulation. Combining INR with sPESI score improved the predictive value for all-cause mortality. However, further large-scale studies are needed to confirm it's prognostic role.

Transvenous extraction of pacemaker and implantable cardioverter defibrillator leads using Evolution® mechanical dilator sheath: a single center confirmatory experience

Objective

In recent years there has been an increase in clinical situations requiring lead extraction procedures of implanted cardiac devices. In our clinic, extraction procedures are performed with Evolution® mechanical lead extraction system. In this manuscript we aimed to evaluate our lead extraction procedures.

Methods

We retrospectively evaluated lead extraction procedures carried out on 41 patients [30 male, 11 female patient; mean age 61.5 ± 18.5 median 67 (23–85)] between 2008 and 2015 using Evolution® system. Procedural success, major and minor complications are determined according to previously published guidelines.

Results

Mean duration of the lead implantation was 88.4 ± 62.5 months (6–240). Implanted device was a pacemaker in 27 (65.8 %) and ICD in 14 (34.2 %) of patients. Total 67 leads were extracted from the patients, 22 (32.8 %) were atrial, 30 (44.2 %) were ventricular, 14 (21.5 %) were dual coil defibrillator and 1 (1.5 %) was coronary sinus lead. Indications for lead removal were pacemaker decubitis and infection in 29 (70.8 %), lead dysfunction in 11 (26.8 %) and subclavian vein thrombosis in 1 (2.4 %) patient. Success rate with Evolution® system without using snare was 85.3 %. Clinical success rate was 97.5 % procedural success rate was 95.1 % and failure occured in one patient. Major complications occured in 2 (4.8 %) patients, 1 (2.4 %) was procedure related mortality. Minor complications were seen in 5 (12.2 %) of patients.

Conclusions

In our single center study it is shown that extraction of pacemaker and defibrillator leads of relatively long implantation duration and in an older age patient group may be successfully carried out using the Evolution® system. However due to potentially serious complications it is adviced to be done by experienced operators in centers with cardiovascular surgery backup.

Percutaneous closure of perimembranous ventricular septal defects associated with septal aneurysm in adults

OBJECTIVE

Percutaneous closure of perimembranous ventricular septal defects (pmVSD) has become an accepted alternative to surgical closure in selected cases. However, closure of pmVSDs associated with septal aneurysm is more challenging. We report our experience of device closure of pmVSDs associated with septal aneurysm.

METHODS

Between 2008 and 2012, percutaneous closure of pmVSD associated with septal aneurysm was attempted in 11 adult patients in our institution. The patients were followed up at 1, 3, 6, and 12 months after the procedure.

RESULTS

Mean age of the patients (64% male, 36% female) was 36.2±1.3 years. Diameter of the left and right ventricular openings of the aneurysm measured by ventriculography was 13.5±5.6 mm and 5.9±2.2 mm, respectively. The defect was occluded with Amplatzer pmVSD Occluder in 4 patients, Amplatzer Muscular Ventricular Septal Defect Occluder in 4 patients, Amplatzer Duct Occluder I in 1 patient, and Amplatzer Duct Occluder II in 2 patients (AGA Medical Corp., Plymouth, MN, USA). The procedure was succesfull in all patients. Mean follow-up time was 22±1.9 months. There was no device- or procedure-related complications at the acute setting or mid-term follow-up.

CONCLUSION

Percutaneous closure of pmVSDs associated with aneurysm is more challenging than that of simple defects. The selection of the device type and size should be made according to the configuration and size of the aneurysm and defect.

[Evaluation of lead extraction procedures using the Evolution Mechanical Dilatator Sheath lead extraction system: A single centre experience]

OBJECTIVE

In recent years, there has been an increase in clinical situations requiring extraction of leads of implanted cardiac devices. This study aimed to evaluate the Evolution Mechanical Dilator Sheath system, presently in use in our clinic for lead extraction procedures.

METHODS

Lead extraction procedures carried out on 20 patients (14 men, 6 women; mean age 61±19; range 23 to 85 years) between 2008 and 2013 using the Evolution system were retrospectively evaluated. Procedural success, and major and minor complications were determined by previously published guidelines.

RESULTS

Mean implantation duration of the leads was 97±65 months (8-204). Fifteen (75%) patients had undergone pacemaker implantation and 5 (25%) had been implanted with a defibrillator. A total of 35 leads were removed from the patients. Seventeen (49%) were ventricular and 12 (34%) were atrial. Five (14%) were defibrillator coils and 1 a coronary sinus lead. Indications for lead extraction were device infection in 18 (90%) patients and lead dysfunction in 2 (10%). Complete procedural success was 95%. Failure occurred in 1 patient. The major complication rate was 5% and minor complications were seen in 25% of patients. No case of mortality was present.

CONCLUSION

In this single centre study, it was shown that extraction of pacemaker and defibrillator leads of longer implant duration may be successfully carried out using the Evolution system. However, due to potentially serious complications it is advised that extraction be done by an experienced operator in centres with cardiovascular surgery facilities.

Impaired quality of life in patients with intermittent atrial fibrillation

Objective:

The quality of life (QoL) is impaired in patients with atrial fibrillation (AF). However, the data on the perceived QoL of patients with different types of AF is limited. In this study, we investigated the QoL of patients with intermittent and chronic AF.

Methods:

The study was designed as an observational cross-sectional study, and 135 consecutive patients with documented AF admitted to the cardiology outpatient clinic in a tertiary hospital were recruited. The pattern of AF was classified as intermittent or chronic AF. The European Heart Rhythm Association (EHRA) classification and symptom severity score were used to quantify the symptoms related to AF. The QoL was assessed by the Short Form-36 and the Canadian Cardiovascular Society Severity in Atrial Fibrillation (SAF) scale.

Results:

Thirty-nine percent of the patients (n=52) had intermittent AF and 61% (n=83) had chronic AF. In the overall patient population, 92% reported having at least one of the symptoms that can be attributable to AF. Although the prevalence of symptoms were similar in patients with intermittent or chronic AF, the patients with intermittent AF perceived more severe palpitations (symptom severity score 2.4±1.7 vs. 1.5±1.5, p=0.003). Patients with intermittent AF had higher EHRA and SAF scores than the patients with chronic AF (2.6±0.9 vs. 1.9±0.8, p<0.001; 2.5±1.3 vs. 1.7±1.2, p<0.001, respectively).

Conclusion:

Outpatients with AF have a high prevalence of symptoms and impaired QoL. The impairment of subjective health-related QoL is worse in patients with intermittent AF.

[Evaluation of quality of life using the Umea 22 questionnaire among patients with atrioventricular nodal tachycardia undergoing successful radiofrequency ablation treatment]

OBJECTIVE

Atrioventricular nodal reentrant tachycardia (AVNRT) attacks is one of the common arrhythmias adversely affecting quality of life. The Umea 22 (U22) is a questionnaire developed for the assessment of symptoms associated with supraventricular tachycardia (SVT), and it is found to be effective in evaluation of quality of life after radiofrequency ablation. Using this questionnaire, the study aimed to assess quality of life among Turkish patients with ANRT before and after the successful RFA.

METHODS

The study was conducted between January 2011 and September 2013, and included 57 patients who had undergone RFA due to AVNRT. The U22 questionnaire was administered pre-procedure and at 6 months post-procedure. The participants were asked to report on their general well-being, arrhythmia effects on their wellbeing, and intensity of discomfort associated with episodes. They were asked to provide a score from 1 to 10 in order to determine to severity of discomfort, and the quantity of symptoms was then assessed according to the visual analogue scale (VAS).

RESULTS

Patients' general wellbeing (7.5±2.3 vs. 8.7±1.8, p<0.001), the effects of arrhythmia episodes on general well-being (8.1±1.7 vs. 1.0±2.1, p<0.001), frequency of symptoms (2.8±0.8 vs. 0.4±0.9, p<0.001) and duration of symptoms were reduced significantly after RFA. The rate of drug use among patients also decreased after RFA (70% vs. 23%, p=0.017).

CONCLUSION

Treatment success was high in patients undergoing RFA due to AVNRT according to the U22 quality of life questionnaire. General and arrhythmia-associated quality of life had improved significantly by the 6th month post-procedure.

Evaluation of aortic elastic properties in patients with exaggerated systolic blood pressure response to exercise testing

We aimed to evaluate the aortic elastic properties in subjects with hypertensive response to exercise stress test (HRE). Sixty-six patients were divided into two groups (33 patients in HRE group and 33 patients in normotensive group). Baseline demographic characteristics were similar. The mean aortic stiffness index (ASI) was significantly higher (p=0.001) whereas aortic distensibility (AD) was significantly lower (p=0.029) in patients suggesting HRE. The C-reactive protein levels of patients with HRE was higher in the HRE group (p=0.03). AD was significantly correlated with age (r=-0.406, p<0.001), pre-test systolic blood presure (SBP) (r=-0.427, p<0.001), peak exercise SBP (r=-0.307, p=0.01), peak exercise diastolic blood presure (DBP) (r=-0.315, p=0.008), and recovery time (3 min) SBP (r=-0.497, p=0.004). Age (β=-0.506, p=0.003) and peak DBP (β=-0.322, p=0.049) were independent predictors of decreased AD. In conclusion, we found a deterioration in arterial elastic properties in patients with HRE.

Epicardial fat thickness is independently associated with psoriasis

BACKGROUND

Several studies have showed an association between psoriasis and cardiovascular (CV) diseases and metabolic syndrome (MS). Assessment of CV risk in patients with psoriasis has become an important issue. Epicardial fat thickness (EFT) is an emerging cardiometabolic risk factor and has been shown to be related to atherosclerosis. EFT has not been studied in the context of psoriasis.

OBJECTIVE

To compare the EFT in psoriasis patients with that in control subjects.

METHODS

31 patients with psoriasis and 32 control subjects were included in this case-control study. EFT was evaluated by two-dimensional transthoracic echocardiography.

RESULTS

EFT was significantly higher in psoriasis patients compared to controls (p = 0.027). Multiple linear regression analysis showed that the association of EFT with psoriasis was independent of MS and age.

CONCLUSION

EFT, which has been suggested as a cardiometabolic risk factor in various diseases, is also independently associated with psoriasis.

Obstruction of superior vena cava flow during transcatheter atrial septal defect closure with the Atriasept ASD occluder

In this paper, we describe a patient with a large secundum atrial septal defect ASD (26 mm) with adequate rims that were suitable for percutaneous closure. While closing this ASD, the superior vena cava (SVC) was occluded with the right atrial disc of the Atriasept ASD occluder (Cardia) and thus the device was retrieved before its release. After retrieval of this device, an Amplatzer ASD occluder was successfully implanted without disturbing the caval flow.

[The efficiency of cutting balloon angioplasty in the treatment of in-stent restenosis]

OBJECTIVE

Although stents reduce the restenosis rate, stent restenosis continues to be a major problem and the optimal treatment of stent restenosis is still controversial. In this study, we aimed to investigate the angiographic recurrent stent restenosis rate at 6-12 months after successful cutting balloon angioplasty (CBA) for the bare metal stent restenosis.

METHODS

Thirty patients (mean age: 57.9 ± 11.6, 22 males) undergoing successful CBA for the treatment of in-stent restenosis at our hospital were prospectively included in this study. Control coronary angiography was performed at 6-12 months after CBA. Lesion length, minimal lumen diameter (MLD), and reference vessel diameter were analyzed by computerized digital angiographic analysis. Recurrent restenosis was defined as the lesions obstructing the lumen more than 50%. We described the lesions shorter than 10 mm as to be focal and those longer than 10 mm as to be diffuse. We used Student t, Chi-square, and Mann-Whitney U tests for statistical analysis.

RESULTS

Two patients had two distinct lesions; therefore, 32 lesions were assessed. There were 9 (28.1%) recurrent restenosis on the control coronary angiography. Recurrent restenosis developed in 3/21 (14.3%) of focal type lesions and 6/11(54.5%) of diffuse type lesions (p=0.035). Pre-procedural MLD was lower in the restenotic group compared to non-restenotic group (0.41 ± 0.29 vs. 0.64 ± 0.17 mm, p=0.048) while percent of stenosis was higher in the restenotic group (76.8 ± 12 vs. 69.6 ± 5.37%, p=0.029).

CONCLUSION

In the selected patients, CBA is an effective and a safe method for the treatment of bare metal stent restenosis. CBA might be considered as a first-line treatment method in patients with focal type lesions.

[Preferences regarding invasive diagnostic procedures in patients aged 70 years or over presenting with acute coronary syndrome and relationship with short-term mortality]

OBJECTIVES

We prospectively classified patients presenting with acute coronary syndrome (ACS) into two age groups, <70 years and ≥70 years, and investigated the frequency of cardiac catheterization, the predictors of cardiac catheterization in the older patient population, and determined early mortality in patients treated with or without cardiac catheterization.

STUDY DESIGN

The study included 1,101 patients admitted with ACS. The patients were prospectively classified in two age groups, <70 years (n=762; mean age 55±9 years) and ≥70 years (n=339; mean age 76±5 years). Data on demographic characteristics, clinical and laboratory findings, and the presence or absence of cardiac catheterization were recorded. The predictors of cardiac catheterization were assessed in the overall patient group and in those ≥70 years of age, and 30-day mortality rates were determined.

RESULTS

Compared with the older group, in younger patients cardiac catheterization was more frequent (74.4% vs. 50.7%, p=0.0001) and earlier (p=0.023), and decision for percutaneous coronary intervention was more common (52.7% vs. 40.7%, p=0.010), whereas coronary bypass grafting was performed more frequently in the older group (43% vs. 31.2%, p=0.010). Overall 30-day mortality rates showed significant differences in both groups between patients treated with or without cardiac catheterization (<70 years: 3.7% vs. 18.3%, p<0.0001; ≥70 years: 5.6% vs. 21%, p<0.0001). Logistic regression analysis showed the following as significant predictors of cardiac catheterization in patients ≥70 years of age: heart failure (OR: 3.853, p=0.017), systolic blood pressure <100 mmHg (OR: 3.602, p=0.008), creatinine clearance <60 ml/min (OR: 2.761, p=0.001), and ST-segment elevation ≥1 mm on the electrocardiogram (OR: 2.817, p=0.0001).

CONCLUSION

Invasive diagnostic and therapeutic strategies are implemented less frequently in elderly patients. These procedures, which offer obvious mortality benefit, should be considered in elderly patients after meticulous risk evaluation.
