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.

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.

Assessment of Contributors of Aortopathy and Subclinical Left Ventricular Dysfunction in Normally Functioning Bicuspid Aortic Valves.

BACKGROUND: Left ventricular (LV) function and the dimensions of aortic valves from normally functioning bicuspid aortic valve (BAV) patients were compared with those of healthy control patients. A comparison between patients with antero-posterior BAV (BAV-AP) or right-left BAV (BAV-RL) was also performed, and the determinants of aortopathy and LV function were investigated. METHODS: Sixty-eight patients with aortic velocities <2 m/s and trivial or mild aortic regurgitation were included in the study. All patients underwent transesophageal echocardiography to diagnose BAV and identify associated phenotypes. Twodimensional (2D), Doppler echocardiographic evaluation, and strain imaging were also performed, and the results compared with those obtained from 55 age- and gender-matched healthy controls. RESULTS: The LV ejection fractions were similar between BAV patients and healthy controls, while LV global longitudinal strain (LVGLS) (p = 0.03) and LV global circumferential strain (LVGCS) (p = 0.02) were significantly lower among BAV patients. Aortic velocities and aortic dimensions at theannulus, sinus of Valsalva and sinotubular junction were significantly greater in BAV patients (all p <0.001). The diameter of the tubular ascending aorta (AA) was correlated with age (r = 0.55, p <0.001), septal E/e' (r = 0.4, p = 0.003), and LV mass index (r = 0.29, p = 0.024). Multivariate analyses revealed that the primary determinant of the AA diameter in BAV patients was age (ß = 0.38, p = 0.04), and enlargement of the AA was independent of the diastolic properties of the left ventricle and LVGLS. No significant differences were observed among the 2D or Doppler echocardiography parameters, nor among strain measurements, between BAV-AP (n = 47) and BAV-RL (n = 21) phenotypes. CONCLUSIONS: Subclinical myocardial dysfunction was observed in BAV patients with normal aortic valve function. LV dysfunction was independent of age, aortic velocity and AA diameter, which suggested the presence of intrinsic myocardial disease. Aging contributes to aortic dilatation in normally functioning BAV.

Prognostic impact of pleural effusion in acute pulmonary embolism.

Background Pulmonary embolism (PE) is a common and life-threatening condition associated with considerable morbidity and mortality. Pleural effusion occurs in about one in three cases; however, data on its prognostic value are scarce. Purpose To investigate the association between pleural effusion and both 30-day and long-term mortality in patients with acute PE. Material and Methods We retrospectively evaluated 463 patients diagnosed with acute PE using computed tomography pulmonary angiography (CTPA). Echocardiographic, demographic, and laboratory data were collected. The study population was divided into two groups: patients with and without pleural effusions. Pleural effusion detected on CT was graded as small, moderate, and large according to the amount of effusion. The predictors of 30-day and long-term total mortality were analyzed. Results Pleural effusions were found in 120 patients (25.9%). After the 30-day follow-up, all-cause mortality was higher in acute PE patients with pleural effusions than in those without (23% versus 9%, P < 0.001). Also, patients with pleural effusions had significantly higher incidence of long-term total mortality than those without pleural effusions (55% versus 23%, P < 0.001). In a multivariate analysis, pleural effusion was an independent predictor of 30-day and long-term mortality (odds ratio [OR], 2.154; 95% confidence interval [CI], 1.186-3.913; P = 0.012 and OR, 1.591; 95% CI, 1.129-2.243; P = 0.008, respectively). Conclusion Pleural effusion can be independently associated with both 30-day and long-term mortality in patients with acute PE.

To Be or Not to Be Patent: The Relationship Between Migraine and Patent Foramen Ovale.

OBJECTIVE/BACKGROUND: Migraine is a common neurological disorder with an uncertain pathogenesis. A pathophysiological link has been proposed between the migraine headache and patent foramen ovale (PFO). However, the data about the association of migraine with the presence of PFO are conflicting. The study aims to prospectively investigate the prevalence of PFO in patients with migraine compared with that of control subjects. METHODS: A total of 203 migraineous patients and 212 control subjects with similar demographic characteristics to that of case subjects regarding age and gender were included in the study. Transthoracic echocardiography with agitated saline injection was used to evaluate the presence of PFO. PFO was judged to be present if any microbubble was seen in the left cardiac chambers within the first 5 cardiac cycles from the maximum right atrial opacification at rest or after provocative maneuvers. RESULTS: Mean age of the patients was 37.2 ± 9.8 years and 93% were female. Migraine with aura was present in 32% (n = 65) of the patients. The prevalence of PFO was similar in patients with migraine and the control subjects (42% vs 44%; odds ratio 0.90, 95% confidence interval 0.61-1.33, P = .61). Likewise, the prevalence of PFO was similar in migraineurs patients with or without aura (41% vs 42%; odds ratio 0.95, 95% confidence interval 0.51-1.76, P = .87). CONCLUSION: This study suggest that PFO is not more common in patients with migraine compared with healthy subjects. Therefore, our findings suggest that the relationship between migraine headache and the presence of PFO is questionable.

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 (ß=-0.506, p=0.003) and peak DBP (ß=-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.

Quality of life of patients with atrial septal defect following percutaneous closure.

INTRODUCTION: Quality of life has become an important outcome measure in addition to mortality and morbidity in patients with congenital heart disease. Atrial septal defect is a common congenital heart disease, and transcatheter atrial septal defect closure has become an accepted treatment modality. The aim of this study is to assess the quality of life of patients with atrial septal defect who underwent percutaneous closure. MATERIALS AND METHODS: We examined the quality of life of 69 patients with atrial septal defect and 69 healthy controls matched according to age, sex, educational level, and economic, marital, and employment status. Quality of life was investigated using the Turkish version of Short Form-36. RESULTS: The mean age of the patients was 39.7 ± 14.2 and 26% were male. The quality of life assessment was performed at a mean follow-up time of 18.0 ± 13.8 months after the intervention. The mean scores of the domains of the Short Form-36, namely, physical functioning, role functioning, social functioning, mental health, vitality, pain, and general health, were similar in patients with atrial septal defect who underwent percutaneous closure and the control group. CONCLUSION: Adult patients who underwent percutaneous atrial septal defect closure perceive their quality of life to be as good as their healthy counterparts.

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]. / Evolution mekanik dilatör kilifli elektrot çikarma sistemi ile yapilan elektrot çikarma islemlerinin degerlendirilmesi: Tek merkez deneyimi.

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.

[Evaluation of quality of life using the Umea 22 questionnaire among patients with atrioventricular nodal tachycardia undergoing successful radiofrequency ablation treatment]. / Basarili radyofrekans ablasyon islemi uygulanan atriyoventriküler nodal reentran tasikardili hastalarda yasam kalitesinin Umea 22 anketi ile degerlendirilmesi.

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.

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.

Rate of blood pressure control and antihypertensive treatment approaches in diabetic patients with hypertension.

OBJECTIVES: Hypertension is a common co-morbidity in patients with type 2 diabetes. Management of hypertension is of paramount importance in reducing macro- and microvascular complications of diabetes. The aim of this study is to determine the rate of blood pressure control (<140/85 mmHg) in diabetic patients with hypertension, and to evaluate the prescribing pattern of antihypertensive medications. STUDY DESIGN: This was a prospective, cross-sectional, observational study conducted in a tertiary centre in Turkey. Of 707 patients with diabetes, 500 hypertensive patients were evaluated to determine control of hypertension and treatment attitudes. Logistic regression analysis was used to evaluate the likelihood of prescription of each class of antihypertensive medications for the presence of macro- and microvascular complications. RESULTS: Most of the patients (95%) were on antihypertensive therapy. Only 41% achieved target blood pressure values (<140/85 mmHg). Renin angiotensin system (RAS) blockers were the most frequently (82.4%) prescribed antihypertensive agents, and a combination of RAS blockers and diuretics were the most commonly preferred combination therapy. Most of the patients were on 1 antihypertensive drug or a combination of 2 drugs (39.5% and 44.7%, respectively). Patients with coronary artery disease were more likely to receive beta blockers (Odds ratio=3.6, 95% confidence interval=2.3-5.6; p<0.001). CONCLUSION: Although most of the diabetic hypertensive patients were on hypertensive therapy, more than half had uncontrolled blood pressure.

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.

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.

Comparison of DDD versus VVIR pacing modes in elderly patients with atrioventricular block.

OBJECTIVES: Dual-chamber pacing is believed to have an advantage over single-chamber ventricular pacing. The aim of this study was to determine whether elderly patients who have implanted pacemakers for complete atrioventricular block gain significant benefits from dual-chamber (DDD) pacemakers compared with single chamber ventricular (VVIR) pacemakers. STUDY DESIGN: This study was designed as a randomized, two-period crossover study-each pacing mode was maintained for 1 month. Thirty patients (16 men, mean age 68.87 ± 6.89 years) with implanted DDD pacemakers were submitted to a standard protocol, which included an interview, pacemaker syndrome assessment, health related quality of life (HRQoL) questionnaires assessed by an SF-36 test, 6-minute walk test (6MWT), and transthoracic echocardiographic examinations. All of these parameters were obtained on both DDD and VVIR mode pacing. Paired data were compared. RESULTS: HRQoL scores were similar, and 6MWT results did not differ between the two groups. VVIR pacing elicited significant enlargement of the left atrium and impaired left ventricular diastolic functions as compared with DDD pacing. Two patients reported subclinical pacemaker syndrome, but this was not statistically significant. CONCLUSION: Our study revealed that in active elderly patients with complete heart block, DDD pacing and VVIR pacing yielded similar improvements in QoL and exercise performance. However, after a short follow-up period, we noted that VVIR pacing caused significant left atrial enlargement and impaired left ventricular diastolic functions.

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.

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.

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.

Post transcatheter aortic valve replacement ejection fraction response is predictor of survival among patients with whole range of systolic dysfunction.

AIMS: The objective of this study is to assess the prognostic effects of T ranscatheter aortic valve replacement (TAVR) on the patients with different degrees of left ventricular systolic (LVS) function and severe symptomatic aortic stenosis. Also examines the prognostic association of LV remodelling after TAVR. METHODS AND RESULTS: Patients stratified into four subgroups with respect to baseline LV ejection fraction (LVEF) (LVEF > 25%, LVEF 25%-40%, LVEF 41%-49% and LVEF ≥ 50%). We compared the baseline characteristics and temporal changes in echocardiographic parameters of the patients after TAVR, and determined all-cause mortality (ACM) in a follow-up period of mean 20.7 ± 15.8 months (up to 84). There were 495 patients at 8 centres. ACM was similar in all groups (28.1%, 29.5%, 22.5% and 24.1% respectively; p = .44). Immediately after TAVR, there was an improvement in LVEF (from 38.7 ± 9.4 to 44.9% ± 10.9%, p < .001). The percent change in LVEF (pDelta-EF) immediately after TAVR was more prominent in the patients with LVEF < 25% (48.1 ± 49.6, 21.9 ± 29.6), (8.4% ± 15.2%) and (2.1 ± 7)) (p < .01). Importantly, a 12% increase in absolute Delta-EF was observed in patients with LVEF< 25% with 100% sensitivity and 42.5% specificity for the prediction of ACM. CONCLUSION: This study shows that TAVR is beneficial in the whole range of LVS function, irrespective of the baseline EF. Early recovery in LVEF after TAVR is critical for survival, however, it seems to be more eye catching in the patients with advanced heart failure with reduced EF.
