Abstract

Purpose: With the advent of percutaneous transcatheter device closures in congenital heart defects and the emergence of percutaneous left atrial appendage closure, there is an increasingly important role for echocardiographic guidance and control of device position and function. Disc occluder devices frequently present as an unexplained ‘figure-of-8’ on echocardiography. The aim of this study was to clarify this ‘figure-of-8’ display and to relate its morphology to transducer position and device type. Methods: A mathematical model was developed to resemble disc occluder geometry and to allow a numerical simulation of the echocardiographic appearance. In addition, we developed an in vitro set-up for echocardiographic analysis of various disc occluders and various transducer positions. Results: In the mathematical model of an epitrochoid curve (closely resembling disc occluder geometry) a ‘figure-of-8’ display is obtained when emphasizing points with tangent vector perpendicular to the direction of ultrasound waves. Decreasing imaging depth results in a more asymmetric ‘figure-of-8’, with small upper part and wide lower part. Clinical and in vitro data are in close agreement with these results (Figure 1). Furthermore a ‘figure-of-8’ display is only obtained in a coronal imaging position, and is similar for different commercially available disc occluder types. Conclusions: The ‘figure-of-8’ display in the ultrasound image of a disc occluder is an imaging artifact due to the specific ‘epitrochoidal’ geometry of a deployed device and its interaction with ultrasound waves. The morphology of the ‘figure-of-8’ depends on transducer position, i.e. imaging depth, and is similar for different device types. Figure 1 Impact of imaging depth

Abstract

Introduction: The conventional radial approach (CRA), the gold standard approach for percutaneous coronary interventions (PCI), is associated with the risk of radial artery occlusion (RAO). The distal radial approach (DRA) is an effective alternative with fewer complications., Aim: To evaluate the efficacy in terms of puncture success and safety by RAO rate of the DRA in elective PCI in Tunisian patients., Methods: It was a randomized controlled non-inferiority trial including patients hospitalized for elective PCI. The protocol was previously published (Tunis Med 2022; 100(3): 192-202). The primary endpoints were puncture success and RAO rate at 30 days., Results: Overall, 250 patients were included and the groups were comparable. The preprocedural examination of the radial pulse and the Barbeau test were similar. The majority of PCIs were coronary angiography (82%). In ITT, respectively in CRA versus DRA, puncture success rates were similar (97.6% versus 96.8%; p≤0.500). RAO rates were similar (2.4% versus 3.2%; p≤0.500). Crossovers were similar. PCI through DRA lasted longer but was not more irradiating, however it required more contrast. Overall bleeding and vascular complications were similar., Conclusion: This study demonstrated the non-inferiority of DRA compared to CRA for elective PCIs in a Tunisian population regarding puncture success and RAO rate at 30 days. Multicenter trials including urgent PCI with systematic ultrasound screening for RAO are needed.

Abstract

Introduction: Simulation-based education (SE) in interventional cardiology improves knowledge acquisition and mastery of procedures including the conventional radial access (CRA)., Aim: To evaluate the contribution of SE in CRA compared with theoretical learning alone., Methods: This is a prospective randomized controlled study including cardiology residents and patients with normal radial pulses. Experienced residents as well as patients with contraindications to CRA, requiring urgent intervention, or with hemodynamic instability were not included. Missing the teaching sessions was the exclusion criteria. Residents were randomized into two groups: simulation versus control. They attended a theory lecture explaining CRA and were evaluated Only the simulation group attended an SE session with measurement of heart rate (HR) and stress level. A real application was then performed with measurement of HR and stress level. The primary outcome was success puncture rate., Results: The success of the puncture was similar between the two groups (p=0.651). In the practical application, the stress level was significantly different before the procedure but similar after the end of the procedure. The stress level varied significantly within the same group before and after the procedure The simulation group was significantly less tachycardic both before and during the procedure with a significant difference between the two groups (p <10-3)., Conclusion: This study demonstrated the interest of SE in novice residents for CRA as a complement to theoretical learning upstream of the real-life procedure.

Abstract

Research Problem: Drug-eluting balloon (DEB) angioplasty is a well-established treatment modality for in-stent restenosis, however its safety and efficacy in de-novo lesion especially in large vessel remains undetermined. Theoretically, DEB sight to eliminate stent thrombosis and reduce restenosis rates by leaving no metal behind., Aim: To compare the results of angioplasty of de novo lesions by DEB (SEQUENT PLEASE) versus DES (Promus Premier and Promus Elite) in a Tunisian population. THE ENDPOINTS will be primarily the Late Lumen Loss at 12 months and secondarily the Major Cardiovascular Event rate (MACE) at 12 months., Investigative Process: This is a randomized controlled non-inferiority trial including 290 patients with chronic coronary disease or non-ST elevation myocardial infarction with de novo lesions. After coronarography, angiographic parameters concerning lesion location and quantitative analysis will be collected. Patients will be treated with DEB or DES according to their allocation group. Before removal of the guide, post-procedural angiographic parameters will be evaluated. Follow-up will be performed for 12 months and an angiographic examination will be performed either as an emergency or at 12 months. The significance level will be 5%. A univariate analysis will be performed to search for predictive factors of MACE., Research Plan: Ethical considerations will be undertaken and respected. The study will run for 15 months starting August 25, 2021 Trial registration: NCT05516446.

Abstract

Research Problem: The conventional radial approach is the recommended vascular access for percutaneous coronary interventions. It is effective and feasible but associated with a risk of occlusion of the radial artery. The distal radial approach is proposed as a new approach to reduce complications and preserve the radial artery. However, few clinical trials in real life were conducted in North African patients. This trial aims to evaluate the efficacy and safety of the distal radial approach versus the conventional radial approach. Investigative process : This trial is a non-inferiority, randomized controlled trial with two parallel arms: distal radial approach and conventional radial approach. Two hundred fifty patients scheduled for percutaneous coronary intervention will be included. The two main endpoints are the puncture success rate with a non-inferiority margin of 10% and the occlusion rate of the punctured radial artery attributed to the end of hemostasis and to 30 days. Secondary Endpoints : catheterization success, crossover rate, procedure time, radial artery spasm, bleeding complications, QuickDASH pain score, Operator satisfaction. A single blind analysis will be led according to the per-protocol and intention-to-treat methods., Research Plan: Ethical considerations will be undertaken and respected. This trial will run for four months from February 2022. The results will provide parameters related to the efficacy and safety of the distal radial approach, improving clinical practice., Trial Registration: NCT05311111.

Abstract

Introduction: Systemic hypertension is a major health problem worldwide, it is associated with impaired left atrial (LA) function. Myocardial deformation analysis using speckle-tracking echocardiography has emerged as a promising tool to evaluate atrial deformation and function., Aim: To evaluate early changes in left atrial longitudinal strain based on speckle tracking echocardiography in patients with hypertension., Methods: LA strain was studied using speckle-tracking echocardiography in 109 hypertensive patients without LA enlargement and 50 agematched controls. Conventional and bidimensional strain echocardiographic assessments were performed and the following parameters were measured: peak atrial longitudinal strain and strain rate during the reservoir, conduit, and contractile periods in four and two-chambers views and time to peak atrial longitudinal strain/strain rate measured in the three phases of LA function., Results: LA anteroposterior diameter was within the normal range, no difference between the hypertensive patients and controls was noted (34.35 mm ±4.91 vs 31.82 mm±4.87, p= 0.16). LA maximum volume (41.78ml±10.29 vs 47ml±13.21, p= 0,01), minimum volume (23.95ml±12.18 vs 16.94ml±7.91, p=0,001) were higher in hypertensive patients, and impaired reservoir ( 31.23% ±9.93 vs 46.43% ±11.06, p=0.000) and conduit functions (14.26%±2.91 vs 21.41%±2.8 , p= 0,000) were noted in hypertensive patients compared to normotensive patients. During the contractile period, peak strain (16.73% ±3.84 vs 15.29%±2.75 ,p=0,07) and strain rate (-1.89%±0.16, -1.82%±0.21;p=0,54) were higher in hypertensive patients without reaching the level of significance. Time to peak strain during reservoir period (405.02ms±55.51 vs 387.13ms±47.48, p=0,05) and duration of diastole (163ms±26 vs 146ms±24, p= 0,04) were significantly higher in hypertensive patients compared to controls. A significant relationship between the parameters of the volumetric study and those of the bidimensional strain/strain rate study was noted., Conclusion: Left atrial longitudinal strain during the reservoir and conduit periods is impaired in patients with hypertension despite normal cavity size and before the detection of other echocardiographic changes. Speckle-tracking echocardiography may be considered a promising tool for the early detection of LA strain abnormalities in these patients.

Abstract

Congenital analbuminemia (CAA) is a very rare disorder with an estimated prevalence of less than one in one million. This anomaly can be lethal at birth and in early infancy but it's not very symptomatic in adulthood. The clinical signs are edema, lipodystrophy, fatigue… Hypercholesterolemia is the main biological disorder and it predisposes to cardiovascular complications. The mild symptoms of CAA leads to delay diagnosis. That's why clinical and biological signs of this disorder should be known by both of biologist and clinician to establish an early diagnosis in order to prevent cardiovascular complications. We report a new case of congenital analbuminemia complicated by recurrent acute coronary artery disease in 34-year-old man. This complication has been reported only once according to the register of analbuminemia cases., (Copyright © 2021 Elsevier Masson SAS. All rights reserved.)

Abstract

Coronary artery aneurysms are uncommon, are usually associated with atherosclerosis, and rarely involve all three major coronary arteries. Data on the optimal choice of acute myocardial infarction (AMI)´s revascularization in the context of polyarteritis nodosa (PAN) is limited to case reports and is still an open question. The present report describes a rare case of a young male patient followed for PAN presenting with acute myocardial infarction (AMI). Coronary angiography revealed multiple severe aneurysmal and stenotic changes. Based on clinical feature and angiographic findings, it was strongly suspected that the AMI was a complication of his vasculitis. This case indicates that coronary artery involvement should be carefully monitored during the chronic phase of PAN. The pathophysiology of AMI in PAN patients should be kept in mind and the interventional approach must be performed according to the angiographic findings to avoid complications., Competing Interests: The authors declare no competing interests., (Copyright: Mayssem Gabsi et al.)

Abstract

Introduction: Early detection of left ventricular (LV) dysfunction may represent a clinical finding that would justify aggressive treatment aimed to reduce cardiovascular morbidity and mortality., Aim: To evaluate longitudinal contractility in patients with essential hypertension and preserved LV ejection fraction (EF), in an attempt to detect latent impairment of LV systolic function., Methods: Prospective case-control study carried out on 121 (67 male/54 female) hypertensive patients (HTN group) with preserved EF and without any symptoms of heart failure and 39 age- and gender-matched healthy subjects as a control group. Conventional echocardiographic study, as well as 2D Longitudinal strain imaging by 2D-speckle tracking echocardiography (2D-STE), were performed., Results: Mean age of patients was 60,48 ± 10.5 years old. The LV end-diastolic diameter and LVEF were comparable between the two groups. Hypertensive patients had greater septal thickness, left ventricular mass, and maximum left atrium volume (p respectively at 0.02; 0.04; and 0.01). Only 20 patients (16.5%) had left ventricular hypertrophy (LVH). The architecture of LV was normal in 57.8 % (n=70) patients. A statistically significant difference between the two groups was found for all diastolic function parameters except Em /Ea ratio and DTEm. In comparison with normal controls, GLS was significantly attenuated in patients with HTN (-17.69 ± 4.06 % versus -22.70 ± 5.02% in controls (p=0.000) and 67 (55.4%) hypertensive patients had a GLS<-20% (in absolute value). The decrease of GLS was more marked in the hypertensive group with left ventricular hypertrophy., Conclusion: The results of our study confirmed that GLS is a sensitive biomarker of subclinical myocardial dysfunction in hypertensive patients, this suggests that identifying patients at higher risk for heart failure and earlier inter¬vention may be beneficial.

Abstract

Background: Analysis of right ventricular (RV) function during the acute phase of pulmonary embolism (PE) was widely reported in the literature. However, few studies analysed its function long term after the acute phase. Our aim was to evaluate the RV function long term after a first episode of PE., Methods: In this study, we compared echocardiographic parameters of right ventricular function in 25 patients with a first episode of non-severe PE for more than six months with 25 healthy controls subject., Results: In the study of RV function, we noted that the mean values of the standard parameters were significantly lower in the EP group compared to the control group but their values remained within the normal range. The global RV longitudinal strain had a mean value lower than the control group statistically significant (-21±4,8% vs. -25±2,4%; P=0,28). The longitudinal strain of the free wall of the RV was altered in the EP group, however, there was no significant difference between the EP group and the control group (-19,4±16% vs. -24±17%; P=0,28)., Conclusion: This study has shown that there is a systolic dysfunction late after a first episode of PE and this despite the absence of the symptoms and pulmonary hypertension., (Copyright © 2020.

Abstract

Introduction: Bioresorbable scaffold (BRS) is a novel device to treat coronary lesions. It may induce a revolution in percutaneous coronary intervention (PCI) and a novel treatment termed vascular restoration therapy. These devices provide short-term scaffolding of the vessel and then dissolve, which would treat the plaque and coronary lumen without inflicting a permanent foreign body in the coronary artery., Aim: This study sought to describe scaffolding in a cohort of Tunisian coronary diseased patients and assess its immediate and mid-term outcomes., Methods: Twenty nine patients with 42 lesions were enrolled. Mean age was 51.4 years. Mean number of scaffolds per patient was 1.57., Results: Our population was at high cardiovascular risk cumulating at least 3 risk factors. Most of them presented with an acute coronary syndrome (66.6%). In 76.1% there were type A/B1 lesions. Moderate calcification was present in 42.2%. Bifurcation lesions were present in 21.3% and just one chronic total occlusion was treated. Clinical device success and clinical procedural success were respectively 93.1% and 90.3%.Using Kaplan-Meier methods. At 18 months : - The major adverse cardiac events (MACE) rate was 44.8%. - The probability of survival without target lesion revascularization (TLR) was 59.5%. - Definite or Possible scaffold thrombosis rate was 6.9%. In our study, BRS implantation was associated with a high rate of adverse events in the longer term except in case of IVUS guidance with respect of Predilatation + Sizing + Postdilatation (PSP) protocol., Conclusion: The theoretical concept of Scaffolding is attractive. One must put into perspective that it is still significantly evolving and improving.

Abstract

Background: The stenosis of the ostial left anterior descending artery represents one of the challenges for the interventional cardiologist. The aim of our study was to define the characteristics of this population and to analyze their results in medium term., Methods: We had undertaken a retrospective study of 76 patients treated in the Cardiology Department of the Military Hospital of Tunis, between January 2014 and March 2017. Percutaneous coronary revascularizations of de novo ostial lesions of the left anterior descending artery were included., Results: The mean age was 59.8 years with a male predominance. Two dilation strategies were adopted: 39% of patients had a "provisional-T-stenting" of the left main coronary artery versus 61% of patients who had a floating stent technic. The main immediate complication was acute occlusion of the circumflex artery ostium. After 12 months, the thrombosis and restenosis rates were 5,2% and 6,5%. Predictors of MACE were: Insulin-requiring diabetes(p=0.05), chronic renal failure(p=0.02), a low-pressure stent deployment(p=0.01), or the presence of signs of left ventricular failure (p<10-3). The predictive factors for stent thrombosis were the alteration of the left ventricular ejection fraction (p<0.01) and the eccentricity of the lesion (p<10-3). Finally, the predictive factors of restenosis were: acute per procedural occlusion of the ostial circumflex artery (p=0.01) or the presence of an associated lesion of distal IVA (p<0,001)., Conclusion: Ostial lesions of the interventricular artery can be re-vascularized by percutaneous angioplasty with acceptable rates of major cardiovascular events. However, the risk of iterative revascularization remains significant.

Abstract

Caseous calcification of the mitral annulus (CCMA) is a rare echocardiographic finding. It is commonly misdiagnosed as an abscess, tumor or infective vegetation on the mitral valve. Since it is a benign process, differentiating it from malignant intra-cardiac mass is primordial to avoid unnecessary surgery. Various imaging modalities can be complimentary for definitive diagnosis. We present a case of CCMA in a 71-year-old female patient. Her medical history revealed hypertension, diabetes mellitus, hyperlipidaemia and coronary artery disease. She was referred to our department for coronary catheterization because of angina symptoms upon minimal exertion. The lesion was detected during echocardiography and was defined as a mass of heterogeneous content with calcification points, located at the posterior side of the mitral valve annulus. Restricted motion of the posterior leaflet and the mass effect caused only minimal mitral regurgitation. To establish the correct diagnosis, we performed the full spectrum of noninvasive cardiac imaging modalities. Transesophageal echocardiography identified well-organized, composite lesion with regular edges, markedly calcified margins and more echolucent central portion. A computed tomography (CT) was performed, showing a hyperdense mass with hypodense center and a calcified peripheral rim located at the posterior mitral ring. Cardiac magnetic resonance imaging (MRI) showed that the mass was hypointense with respect to the myocardium in the T1 and T2-weighted sequences and only presented late-phase enhancement in the surrounding capsule. Based on the CT and MRI findings, the diagnosis of CCMA was established. The patient was managed conservatively.

Abstract

Background - Acute coronary syndrome with high level of troponin is a common pattern for emergency consultation. In 10% of cases, coronary angiography concluded that there were no significant coronary lesions. The contribution of cardiac magnetic resonance imaging (MRI) in the etiological investigation is increasing in these conditions. Aim - We analyzed the diagnostic value of cardiac MRI in case of acute coronary syndromes with elevated troponin and normal coronary angiography. Methods - It's a retrospective analytical study including 31 patients presenting with acute coronary syndrome with positive troponins and normal coronary angiography. All these patients underwent cardiac MRI. Results - The average age was 44.94 years. Cardiovascular risk factors were present in 38.70%. The average level of troponin was 4.85 ng/ml. Modification in the ST segment was noted in 87.1% of which 51.6% had ST elevated segment. Cardiac MRI was performed in the average of 8 days. MRI has contributed to the diagnosis in 77.4%: a myocardial infarction (MI) with no significant coronary lesions in 38.7% of cases, myocarditis in 29% of cases, Tako-Tsubo syndrome in 6.5% of cases and apical HCM in 3.2% of cases. MRI was normal in 22.6% of cases. Conclusions - The contribution of cardiac MRI is growing in the diagnostic management of patients with chest pain, elevated level of troponin and normal coronary angiography. The differential diagnoses have discriminating characteristics in MRI, allowing their identification with excellent diagnostic accuracy. The two main etiologies are myocardial necrosis and myocarditis.

Abstract

Mediterranean spotted fever (MSF) due to Rickettsia conorii is the most important tick-borne disease occurring in North Africa. The first description of MSF was made by Conor and Brush in 1910 in Tunisia. Clinical diagnosis relies on the association of fever, rash and inoculation's scar during summertime. Prognosis in MSF is usually good, however malignant forms were described. These forms occur in patients with comorbidities. G6PD deficiency is a classic ground for severe forms of MSF. Myocarditis is an uncommon complication in MSF; only few cases were reported in the literature. We report a new case of myocarditis complicating MSF in a 15-year-old patient with G6PD deficiency. The patient presented with fever and rash, evocative of MSF; he reported chest pain and the electrocardiogram showed ST segment elevation in anterior leads. Troponin level was elevated. Echocardiogram showed left ventricular dysfunction with 40% ejection fraction. Serologic tests confirmed R. conorii recent infection. Antibiotic treatment with vibramycine and rifadine was started. Patient also received classic treatment of myocarditis with left ventricular dysfunction associating CEI, ß-bloquers and diuretics. Evolution was favourable with complete recovery of left ventricular function. Myocarditis is an uncommon but severe complication of MSF. Early diagnosis and treatment allow favorable evolution., (Copyright © 2011. Published by Elsevier SAS.)

Abstract

Cannabis is the most widely used illicit drug in the world. It is generally considered to be a drug with low toxicity. Nevertheless, there are several case reports of myocardial infarction following cannabis use in otherwise low-risk individuals. We report the first case of a cannabis user presenting with acute coronary syndrome related to multivessel coronary artery dissection.
