RESUMO
BACKGROUND: Percutaneous balloon mitral valvuloplasty (PBMV) is the ACC/AHA class I recommendation for treating symptomatic rheumatic mitral stenosis with suitable valve morphology, less than moderate MR and absence of left atrium clot. The mitral valve restenosis and significant mitral regurgitation (MR) are known adverse outcomes of PBMV. This study aimed to evaluate the outcomes of PBMV in patients with severe mitral stenosis and the effect of Commissural Calcification (CC) on the outcomes. METHODS: In this single-center retrospective cohort study, 876 patients who underwent PBMV were categorized into three groups based on their Wilkins score (Group I: score ≤ 8, Group II: score 9-10, and Group III: score 11-12). Patients were evaluated before, early after PBMV and at 6- and 24-month follow-ups. Main clinical outcomes were defined as significant restenosis and or symptomatic significant MR (moderate to severe and severe MR) or candidate for mitral valve replacement (MVR). The outcomes were compared between patients with and without CC. RESULTS: A total of 876 patients with mean age 46.4 ± 12.3 years (81.0% females) were categorized based on Wilkins score. 333 (38.0%) were in Group I, 501 (57.2%) were in Group II, and 42 (4.8%) were in Group III. CC was present in 175 (20.0%) of the patients, among whom 95 (54.3%) had calcification of the anterolateral commissure, 64 (36.6%) had calcification of the posteromedial commissure, and in 16 (9.1%) patients both commissures were calcified. There was a significant difference in Wilkins score between patients with and without CC (P < 0.001). CC was associated with higher odds of significant symptomatic MR at early and mid-term follow up (OR: 1.69, 95%CI 1.19-2.41, P = 0.003; and OR: 3.90, 95%CI 2.61-5.83, P < 0.001, respectively), but not with restenosis (P = 0.128). Wilkins Groups II and III did not show higher odds of significant symptomatic MR compared to Group I at early (II: P = 0.784; III: P = 0.098) and mid-term follow up (II: P = 0.216; III: P = 0.227). Patients in Wilkins Group II had higher odds of restenosis compared to Group I (OR: 2.96,95%CI: 1.35-6.27, P = 0.007). CONCLUSION: Commissural calcification (CC) is an independent predictor of the significant symptomatic MR (an important determinant of adverse outcome) following PBMV in the early and mid-term follow-up. Mitral valve restenosis occurs more in patients with higher Wilkins score compared to group I with score ≤ 8. Combined Wilkins score and CC should be considered for patient suitability for PBMV.

PURPOSE: Left ventricular (LV) dysfunction can be assessed by quantifying LV structure. In this study, physical parameters were extracted, including the systolic strain, wall stress, and elastic modulus of LV to diagnose stent candidate patients from the control group. METHODS: Based on angiography results, 88 patients with coronary artery disease (CAD) were divided into 64 patients candidates for PCI (percutaneous coronary intervention) and 24 patients in the control group. With the thick-walled ellipsoidal model, the passive wall stresses at end-systole and end-diastole were estimated. Regional circumferential strain and regional longitudinal strain were obtained by speckle tracking technique. RESULTS: The inferoseptal circumferential wall stress in end-systole was statistically significant for the PCI group compared to the control group (p = .026). Anterior and inferoseptal circumferential strain for the PCI group (-17.25 ± 4.22 and -18.21 ± 4.04%) compared to the control group (-21.71 ± 4.74 and 20.58 ± 3.04%) were statistically significant, respectively (p = .000 and p = .011). Anterior and inferoseptal circumferential elastic modulus were statistically significant (p = .000 and p = .005). The receiver operator characteristic (ROC) curve analysis revealed that anterior and inferoseptal circumferential elastic modulus had the highest area under the curve with 76.6% sensitivity, 83.3% specificity for anterior circumferential, 68.8% sensitivity, and 70.8% specificity for inferoseptal circumferential, for the diagnosis of stent candidate patients. CONCLUSIONS: Regional elastic modulus parameter is suggested as a noninvasive and quantitative method for measuring LV function. Strain and stress parameters using the STE method and geometrical model can be helpful for diagnostic stent candidate patients.

Background: The shape of the left ventricle (LV) is an important index to explore cardiac pathophysiology. A comparison was provided to estimate circumferential, longitudinal, and radial wall stress in LV based on the thick-walled ellipsoidal models of Mirsky and Ghista-Sandler for discriminating significant coronary artery disease (CAD) patients from no CAD patients. Materials and Methods: According to the angiography findings, 82 patients with CAD were divided into two groups: 25 patients without significant CAD and 57 patients with significant CAD of single vessel and multivessel. An ellipsoidal LV geometry was used to calculate end-systolic passive stress as the mechanical behavior of LV. Echocardiographic views-based measurements of LV diameters used to estimate the end-systolic wall stress. Results: Circumferential wall stress between the control group and significant CAD groups was significantly elevated for the Ghista model (P = 0.008); also, radial and longitudinal stress of the multi-vessel CAD group was significantly higher than the control group (P = 0.01 and P = 0.005, respectively). All stress parameters of the multi-vessel CAD group were statistically significant compared to the control group for the Mirsky model. Receiver operating characteristics curve analysis was shown the circumferential stress of multi-vessel CAD with an area under the curve (AUC) of 0.736 for the Ghista model and an AUC of 0.742 for the Mirsky model. Conclusion: These results indicated that Ghista and Mirsky model estimates of circumferential passive stress were the potential biomechanical markers to predict patients with multi-vessel CAD. It could be a noninvasive and helpful tool to quantify the contractility of LV.
RESUMO
BACKGROUND: Coarctation of the aorta is a common cardiac disease in Turner syndrome. Evidence indicates that surgery and balloon angioplasty in infants and small children do not have any added risk of mortality or complication in these patients. Stenting in older patients may, however, pose higher risks of arterial wall injury and mortality. METHODS: In this case series, we describe 15 patients with coarctation of the aorta in Turner syndrome: 9 received stenting, 4 underwent surgery, and 2 were treated via balloon angioplasty. RESULTS: Dissection occurred in 2 patients after stenting: 1 in the aorta and the other in the external femoral artery. Both were managed promptly without any mortality or serious damage, one percutaneously and the other surgically. CONCLUSIONS: Awareness of increased risks and preparedness for prompt interventions in case of an acute arterial wall injury are recommended when coarctation stenting is done for a patient with Turner syndrome.

BACKGROUND: Trans-catheter device closure of secundum type atrial septal defects (ASDs) has now become the treatment of choice. Device closure affects the hemodynamics and function of the heart. In the current study, we investigated the remodeling of the heart as assessed by advanced echocardiographic parameters following successful device closure. METHODS: A prospective cohort study was conducted and 45 patients who were eligible for ASD device closure were evaluated for volumetric, functional, Doppler, strain, and strain rate data of left and right atrium and ventricle pre-procedural and 48 h post-procedure RESULTS: In a prospective cohort study 45 patients who were eligible for ASD device closure; atrial and ventricular volumetric, functional, Doppler, strain, and strain rate data were recorded and compared pre-procedurally and 48 h post-procedure.We found significant changes in the left ventricular (LV) end diastolic volume index (p-value = .03), right ventricular (RV) diameter (p-value = <.001), left atrial (LA) volume index (p-value = .05), right atrial (RA) volume index (p-value = .001), and right and left sided E/e' ratio with a p-value of .001 and .004, respectively. Our findings showed a significant reduction in the strains of the right and left atria and the right ventricular free wall after ASD device closure. LV global longitudinal strain decreased after the procedure but did not reach statistical significance. CONCLUSION: ASD patients have impaired global strains compared to normal defined ranges. LA, RA, and RV strains show significant reduction after device closure. Decline in LA function following closure was greater in those with larger ASDs. In adult patients undergoing the procedure, abnormal LA function is a clinically relevant issue demanding pre and post- procedural precautions and treatment.

Bioprosthetic valve thrombosis (BPVT) is a growing recognized entity, especially with the increasing use of the valve in vale procedures and the advent of new detection technologies (e.g., 4D CT and 4D echocardiography). The incidence of BPVT is higher in transcatheter valves than surgically implanted bioprosthetic valves. However, the best thromboprophylaxis regimen and optimal management strategy in the acute context remain unknown. This paper presents a case of early thrombosis following the percutaneous tricuspid valve in vale procedure that was successfully managed with thrombolysis.

Ductus arteriosus is a physiological structure if not closed after birth, may lead to many complications. Today, trans-catheter closure of patent ductus arteriosus with Occluder devices is the preferred method. Surgical ligation is used only in certain cases such as large symptomatic patent ductus arteriosus in very small infants and premature babies; unfavourable structure of the duct or economic considerations. In this article, we described haemodynamic and morphological characteristics of five patients with large patent ductus arteriosus which were occluded with Amplatzer device.From 23 January, 2010 to 31 July, 2018, five patients referred to our clinic with large patent ductus arteriosus and pulmonary arterial hypertension for further evaluation. After assessing them with various diagnostic methods, we decided to close defect with ventricular septal defect Occluder device. Patients aged 21-44 years and one of them was male. Ductus closure was successfully done with ventricular septal defect Occluder device. Closure was successful for all of them but in one case, whose device was embolized to pulmonary artery after 24 hr and he underwent surgery.Trans-catheter closure of large patent ductus arteriosus in adult patients with pulmonary hypertension is feasible. Despite the fact that complications may occur even with the most experienced hands, the 'double disk' Amplatzer ventricular septal defect muscular Occluder could be advantageous in this setting.

AIM: Noninvasive fractional flow reserve (NiFFR) is an emerging method for evaluating the functional significance of a coronary lesion during diagnostic coronary angiography (CAG). The method relies on the computational flow dynamics and the three-dimensional (3D) reconstruction of the vessel extracted from CAG. In the present study, we sought to evaluate the diagnostic performance and applicability of 2D-based NiFFR. METHODS: In this prospective observational study, we evaluated 2D-based NiFFR in 279 candidates for invasive CAG and invasive fractional flow reserve (FFR). NiFFR was calculated via two methods: variable NiFFR, in which the contrast transport time was extracted from the angiographic view, and fixed NiFFR, in which a prespecified frame count was applied. RESULTS: The final analysis was performed on 245 patients (250 lesions). Variable NiFFR had an area under the receiver operating characteristic curve of 81.5%, an accuracy of 80.0%, a sensitivity of 82.2%, a specificity of 82.2%, a negative predictive value of 91.4%, and a positive predictive value of 63.6%. The mean difference between FFR and NiFFR was -0.0244 ±.0616 (p ≤.0001). A pressure wire-free hybrid strategy was possible in 68.8% of our population with variable NiFFR. CONCLUSIONS: Our 2D-based NiFFR yielded results comparable to those derived from 3D-based software. Our findings should; however, be confirmed in larger trials.

Intravascular ultrasound (IVUS) has been introduced as an accurate and minimally invasive diagnostic technique for the assessment of vascular anatomy and its abnormalities. We believe that IVUS can be used for clarifying the reasons for failure of balloon angiography in infantile coarctation of the aorta (CoA), because post-balloon angioplasty tearing, intimal flap, thrombosis and pseudoaneurysm of the aorta can be evaluated by IVUS with greater sensitivity and specificity. We aimed to assess the outcome of balloon angioplasty of CoA using angiography as the gold standard and IVUS as a new method in infants, comparing the two techniques for the evaluation of the diameter and area of CoA segment pre- and post-procedure. This cross-sectional study was performed on 18 infants hospitalized with a final diagnosis of CoA. All the infants underwent angiography and were also assessed by IVUS to measure the preoperative and postoperative diameter of the narrow segment in the two anterior-posterior and lateral views. In assessment by IVUS, the mean diameter of the coarctation site increased from 2.10 ± 0.30 mm to 4.50 ± 0.94 mm (P < 0.001). Similarly, the average minimum area of the coarctation level increased from 5.26 ± 1.50 mm2 to 13.77 ± 3.48 mm2 after angioplasty (P < 0.001). Comparing these findings, angiography and IVUS showed a high level of agreement. In the assessment of a dissection flap, there was a high level of agreement between angioplasty and IVUS before the procedure, but IVUS had higher accuracy after the procedure. Our study showed that IVUS was more reliable than angiography in the assessment of residual coarctation. IVUS yielded high sensitivity (58.3%) and specificity (100%) for discriminating the presence and absence of residual coarctation as well as the need for repeating the procedure. The assessment of coarctation before and after angioplasty procedures in children is possible using the IVUS method, with high accuracy. IVUS can offer greater accuracy than angiography in the evaluation of the coarctation area, detecting tears, dissection and flaps, and assessment of residual coarctation.

Transcatheter closure of secundum-type atrial septal defects has become the treatment of choice in the majority of cases. Femoral venous access is the standard rout for device implantation. Anatomic abnormalities of venous system including interrupted inferior caval vein with azygous continuation can make the percutaneous procedure more complicated. In such instances, alternative methods of transjugular or transhepatic approach or surgical repair should be considered. We present the case of a 50-year-old male with secundum-type atrial septal defect and a rare form of segmental interruption of inferior caval vein and describe successful atrial septal defect closure through transfemoral approach.

BACKGROUND: Percutaneous mitral commissurotomy (PMC) is currently the treatment of choice for patients with symptomatic mitral stenosis (MS) that have favorable valvular characteristics. We aimed to evaluate the effect of PMC on the longitudinal strain of the right ventricular (RV) free wall in patients with severe MS. METHODS: This prospective study recruited patients who underwent PMC. Transesophageal and transthoracic echocardiographic examinations were performed. The mitral valve area (MVA) was measured by three-dimensional evaluation. The RV longitudinal strain was measured via the speckle-tracking method. RESULTS: A total of 42 patients with a maximum MVA of 1.5 cm2 underwent PMC in our study. The MVA increased significantly after the procedure (pre-PMC MVA = 0.94 ± 0.20 cm2 vs post-PMC MVA = 1.45 ± 0.18 cm2 ; P < .01). Systolic pulmonary artery pressure decreased from 46.05 ± 14.08 mm Hg preprocedurally to 35.86 ± 7.53 mm Hg postprocedurally (P < .01). The mean RV free wall longitudinal strain was -19.00 ± 5.14%, which rose significantly after PMC to -20.97 ± 3.81 (P < .05). There were postprocedural increases, albeit nonsignificant, in the tricuspid annular peak systolic excursion, the peak systolic Doppler velocity of the RV free wall, and fractional area change. The improvement in the RV longitudinal strain was more prominent in the patients with an MVA of less than 1.0 cm2 . CONCLUSIONS: There was a significant post-PMC rise in the RV free wall longitudinal strain measures in our study population, demonstrating an immediate improvement in the RV systolic function of the patients.

BACKGROUND: The metabolic syndrome (MetS), as a combination of cardiovascular risk factors, is associated with subclinical cardiovascular diseases. We sought to evaluate the subclinical myocardial dysfunctions using echocardiography in patients with normal coronary arteries. MATERIALS AND METHODS: In this cross-sectional study, we assessed 50 consecutive patients with angiographically-proven normal coronary arteries and a left ventricular (LV) ejection fraction (EF) ≥55%. The diagnosis of MetS was based on the National Cholesterol Education Program/Adult Treatment Panel III criteria. All patients were examined using conventional and two-dimensional speckle tracking echocardiography for evaluating the myocardial functions. RESULTS: The patients' mean age was 52.3 ± 8.3 years with 32 females (64%). LV EF, mass index, and full volume were comparable between groups. The LV myocardial performance index (0.40 ± 0.13 vs. 0.32 ± 0.10; P = .027), global longitudinal strain (GLS, -15.8 ± 4.5 vs. -19.7 ± 2.1; P < .001), and global circumferential strain (-17.9 ± 6.1 vs. -21.5 ± 3.3; P = .014) were different between patients with or without MetS, respectively. The GLS discriminated patients with MetS (area under the curve = 0.837, sensitivity 80%, specificity 88%, P < .001). CONCLUSIONS: In MetS without coronary artery disease, echocardiography demonstrated subclinical systolic and diastolic dysfunction.

INTRODUCTION: The mitral valve area (MVA) poorly reflects the hemodynamic status of (MS). In this study, we compared the MVA with mitral valve resistance (MVR) with regard to the determination of hemodynamic consequences of MS and the immediate outcomes of percutaneous balloon mitral valvuloplasty (PBMV). METHODS: In a prospective study, 36 patients with severe rheumatic MS with left ventricular ejection fraction (LVEF) >50% were evaluated. They underwent transthoracic echocardiography (TTE) and catheterization. The MVA was measured by two-dimensional planimetry and pressure half-time (PHT), and the MVR was calculated using the equation: 1333 × transmitral pressure gradient mean transmitral diastolic flow rate. RESULTS: The patients' mean age was 47.8±10.5 years. MVR ≥140.6 dynes·s/cm5 detected systolic pulmonary arterial pressure (sPAP) >55 mm Hg with a sensitivity of 100% and a specificity of 74%. The sensitivity and specificity of MVA<0.75 cm2 to discriminate elevated sPAP were 81% and 89%, respectively. PHT ≥323.5 mseconds had a sensitivity of 78% and a specificity of 96% to detect an elevated sPAP. To predict a successful PBMV, preprocedural MVR ≥106.1 dynes·s/cm5 had a sensitivity of 100% and a specificity of 67% (area under the curve [AUC]=0.763; 95% confidence interval [CI]=0.520-1.006; P=.034); preprocedural MVA <0.95 cm2 had a sensitivity of 78% and a specificity of 73% (AUC=0.730; 95% CI=0.503-0.956; P=.065); and preprocedural PHT ≥210.5 mseconds had a sensitivity of 73% and a specificity of 78% (AUC=0.707; 95% CI=0.474-0.941; P=.095). CONCLUSIONS: MVR seems to be more accurate than MVA in determining the hemodynamic consequences of severe MS as determined by sPAP. In addition, preprocedural MVR detected successful PBMVs.

BACKGROUND: Measuring coronary artery calcium score (CACS) using a dual-source CT scanner is recognized as a major indicator for assessing coronary artery disease. The present study aimed to validate the clinical significance of CACS in predicting coronary artery stenosis and its severity. MATERIAL/METHODS: This prospective study was conducted on 202 consecutive patients who underwent both conventional coronary angiography and dual-source (256-slice) computed tomography coronary angiography (CTA) for any reason in our cardiac imaging center from March to September 2013. CACS was measured by Agatston algorithm on non-enhanced CT. The severity of coronary artery disease was assessed by Gensini score on conventional angiography. RESULTS: There was a significant relationship between the number of diseased coronary vessels and mean calcium score, i.e. the mean calcium score was 202.25±450.06 in normal coronary status, 427.50±607.24 in single-vessel disease, 590.03±511.34 in two-vessel disease, and 953.35±1023.45 in three-vessel disease (p<0.001). There was a positive association between calcium score and Gensini score (r=0.636, p<0.001). In a linear regression model, calcium score was a strong determinant of the severity of coronary artery disease. Calcium scoring had an acceptable value for discriminating coronary disease from normal condition with optimal cutoff point of 350, yielding a sensitivity and specificity of 83% and 70%, respectively. CONCLUSIONS: Our study confirmed the strong relationship between the coronary artery calcium score and the presence and severity of stenosis in coronary arteries assessed by both the number of diseased coronary vessels and also by the Gnesini score.
RESUMO
Key Clinical Message: Transcatheter mitral valve implantation (TMVI) is considered a less-invasive approach than open-heart surgery, favored in high-risk patients elected for valve replacement. Although seemingly suitable, this procedure is highly operator-dependent. Abstract: Transcatheter mitral valve implantation (TMVI) is an alternative in high-risk patients. We reported a 72-year-old patient with mitral bioprosthesis degeneration successfully receiving TMVI. The procedure has lower morbidity and mortality rate than the surgical approach but can be accompanied by several complications, especially when conducted by an inexperienced operator.
RESUMO
BACKGROUND: Cardiovascular events and poor quality of life are frequently observed in patients with coronary slow flow phenomenon (CSFP). This trial evaluated the effect of nano-curcumin supplement containing curcuminoids, as multifunctional nutraceuticals, on angina status, and some traditional and novel cardiovascular risk factors in overweight or obese patients with CSFP. METHODS: In this double-blind, randomized, placebo-controlled clinical trial, 42 overweight or obese patients with CSFP received either 80 mg/day of nano-curcumin or placebo for 12 weeks. Seattle angina questionnaire (SAQ) as a clinical measure of angina status, circulating endocan, adropin, homocysteine, lipid profile, and the novel scores of visceral adiposity index (VAI) and waist-triglyceride index (WTI) were assessed before and after the intervention. The independent samples t-test, Mann-Whitney test, analysis of covariance, Chi-square, and Fisher's exact tests were used where appropriate. RESULTS: All domains of SAQ including physical limitation, angina stability, angina frequency-severity, treatment satisfaction, and disease perception and quality of life improved significantly in the nano-curcumin compared with the placebo group. No significant changes were observed in serum endocan, adropin, and homocysteine following the intervention. Triglycerides, triglyceride/high-density lipoprotein cholesterol ratio, WTI and VAI values improved significantly only within the nano-curcumin group. CONCLUSIONS: Supplementation with 80 mg/day nano-curcumin (containing curcuminoids) for 12 weeks significantly improved clinically important disease-specific aspects of health in patients with CSFP. Some traditional and novel cardiovascular risk factors improved significantly only compared with the baseline values, which need further investigation. TRIAL REGISTRATION: This study was approved by the Ethics Committee of Tehran University of Medical Sciences (IR.TUMS.VCR.REC.1398.794). The study protocol was registered at Iranian Registry of Clinical Trials by IRCT20131125015536N8 registration ID at 19.06.2019.
RESUMO
BACKGROUND/OBJECTIVES: This study was designed to investigate whether garlic powder tablets in adjunct to conventional medical treatment could have an effect on carotid intima-media thickness (CIMT) and plasma lipoproteins and lipids in patients with coronary artery disease (CAD). SUBJECTS/METHODS: A randomized, placebo-controlled, clinical trial was conducted on 56 patients with CAD between the ages of 25 and 75 years. The patients were randomly divided into two groups: garlic group (n = 27), receiving garlic powder tablet (1200 µg allicin/tab) twice daily and the placebo group (n = 29), receiving placebo for 3 months. The rate of atherosclerosis progression was measured by B-mode ultrasonography as the increase in CIMT. RESULTS: After 3 months of taking garlic tablets, CIMT values had minor variations (0.009 ± 0.007 mm reduction from baseline), while in the placebo group, an increase in CIMT values was observed (0.04 ± 0.01 mm increase from baseline). After 3 months of treatment, mean CIMT difference from baseline was significantly differ between the two groups (p < 0.001). Plasma lipids and lipoproteins (total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, Apolipoprotein A1 and Apolipoprotein B) did not differ between the two groups. CONCLUSIONS: The results suggest that dry garlic powder tablet is superior to placebo in prevention of CIMT progression in patients with CAD and may be considered as an adjunct treatment for atherosclerosis.
