Background:
Left ventricular ejection fraction (LVEF) is calculated from volumetric change without representing true myocardial properties. Strain echocardiography has been used to objectively measure myocardial deformation. Myocardial strain can give accurate information about intrinsic myocardial function, and it can be used to detect early-stage cardiovascular diseases, monitor myocardial changes with specific therapies, differentiate cardiomyopathies, and predict the prognosis of several cardiovascular diseases. Sacubitril/valsartan has been shown to improve mortality and reduce hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF). The effect of sacubitril/valsartan angiotensin receptor neprilysin inhibitor (ARNI) on left ventricular (LV) ejection fraction (EF) and torsion dynamics in HFrEF patients has not been previously described.
Methods:
The study involved 73 patients with HFrEF, for all patients Full history was taken, full clinical examination was done. Baseline vital signs, ECG, NYHA classification, conventional echocardiography and STE were done at baseline study and after 6 and 11 months.Basal and apical LV short-axis images were acquired for further off-line analysis. Using commercially available two-dimensional strain software, apical, basal rotation, and LV torsion were calculated.
Results:
ARNI group of patients showed improvement of symptoms, LV global longitudinal strain (LVGLS)% and diastolic parameters including, E/A, E/e', TV, untwist onset and rate after 6 months of therapy in comparison to the traditionally treated patients. The improvement continued for 11 months with in additional significant improvement of systolic parameters in the form of LVGLS%, EF%, Twist, Apical and basal rotations, main dependent parameters for improvement of EF% was LVGLS% and Apical rotation.
Conclusion:
To the best of our knowledge, this is the first study to demonstrate that therapy with sacubitril/valsartan in HFrEF patients could create a state of gradual and chronic LV deloading which cause relieving of myocardial wall tensions and decreasing the LV end diastolic pressure this state could cause cardiac reverse remodeling and reestablishment of starling forces proprieties of LV myocardium, which lead to increase of LV EF.

Background:
The great technological advancements in the field of echocardiography have led to applications of stress echocardiography (SE) in almost all diagnostic fields of cardiology, from ischemic heart disease to valvular heart disease and diastolic function. However, the assessment of the right ventricle (RV) in general, and in particular in regard to the contractile reserve of the RV, is an area that has not been previously explored. We, therefore, propose a study to investigate the potential use of SE for the assessment of RV function in adult patients.
Aims and objectives:
The primary aim is to evaluate the feasibility of right ventricular SE. The secondary aim is to assess right ventricular contractile reserve.
Matherials and Methods:
Eighty-one patients undergoing a physical or dobutamine stress echocardiogram for cardiovascular risk stratification or chest pain were the subject of the study. An exercise leg cycle using a standard WHO protocol was used to simultaneously assess the right and left ventricular global and regional function as well as acquiring Doppler data. Whereas the patient had limitations in mobility, a dobutamine SE was be performed. We evaluated the average values of tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), S-wave, systolic pulmonary artery pressure (sPAP), and right ventricle global longitudinal (free wall) strain (RVGLS) during baseline and at the peak of the effort. RV contractile reserve was defined as the change in RVGLS from rest to peak exercise. We also assessed the reproducibility of these measurements between two different expert operators (blind analysis).
Results:
At least 3 over 5 RV function parameters were measurable both during baseline and at the peak of the effort in 95% of patients, while all 5 parameters in 65% of our population, demonstrating an excellent feasibility. All RV-studied variables showed a statistically significant increase (
P
< 0.001) at peak compared to the baseline. The average percentage increases at peak were 31.1% for TAPSE, 24.8% for FAC, 50.6% for S-wave, 55.2% for PAPS, and 39.8% for RV strain. The reproducibility between operators at baseline and peak was excellent. Our study demonstrates that TAPSE, FAC, and S-wave are highly feasible at rest and at peak, while TAPSE, S-wave, and sPAP are the most reliable measurements during RV stress echo. Conclusion: RVGLS is useful in the assessment of RV contractile reserve in patients with good acoustic window. Further studies are needed to evaluate the impact of contrast echocardiography in improving RV contractile reserve assessment during SE.

Andrea Sonaglioni, Elisabetta Rigamonti, Gian Luigi Nicolosi, Michele Lombardo
April-June 2021, 31(2):85-95
DOI
:10.4103/jcecho.jcecho_141_20
Background:
The influence of chest conformation on outcome of patients with suspected coronary artery disease (CAD) is actually unknown.
Materials
and
Methods:
This retrospective study included all consecutive patients who underwent exercise stress echocardiography (ESE) for suspected CAD at our institution between February 2011 and September 2019. Modified Haller index (MHI; chest transverse diameter over the distance between sternum and spine) was assessed in all patients. Obstructive CAD was diagnosed by ≥70% stenosis in any epicardial coronary artery. During the follow-up time, we evaluated the occurrence of any of the following: (1) cardiovascular (CV) hospitalizations and (2) cardiac death or sudden death.
Results:
A total of 1091 consecutive patients (62.4 ± 12.6 years, 57.2% of men) were included in the study. Patients with normal chest shape (MHI ≤2.5) and those with concave-shaped chest wall (MHI >2.5) were separately analyzed. A positive ESE was diagnosed in 171 patients of which 80.7% had an obstructive CAD (true positive), while 19.3 not (false positive [FP]). Majority of FP ESE (70.9%) derived from concave-shaped chest wall group. During follow-up time (2.5 ± 1.9 years), 9 patients died and 281 were hospitalized because of heart failure (163), acute coronary syndromes (39), and arrhythmias (79). At the multivariate Cox regression analysis, age (heart rate [HR]: 1.02, 95% confidence interval [CI]: 1.01–1.03), MHI >2.5 (HR: 0.39, 95% CI: 0.26–0.56), diabetes mellitus (HR: 4.89, 95% CI: 3.78–6.32), horizontal ST depression ≥1 mm (HR: 2.86, 95% CI: 1.98–4.15), peak exercise average E/e' ratio (HR: 1.08, 95% CI: 1.06–1.10), and peak exercise wall motion score index (HR: 1.79, 95% CI: 1.36–2.35) were independently correlated with outcome.
Conclusions:
Patients with concave-shaped chest wall (MHI >2.5) have a significantly lower probability of CV events than those with normal chest shape (MHI ≤2.5) over a medium-term follow-up. A noninvasive chest shape assessment could identify subjects at lower risk of CV events.

Effect of percutaneous coronary intervention on diastolic function in coronary artery disease
Puneet Aggarwal, Santosh Kumar Sinha, Rishabh Marwah, Ranjit Kumar Nath, Bhagya Narayan Pandit, Ajay Pratap Singh
April-June 2021, 31(2):73-76
DOI
:10.4103/jcecho.jcecho_128_20
Background:
Left ventricle (LV) diastolic dysfunction is often present in patients with significant coronary artery disease (CAD), even in the absence of regional or global LV systolic dysfunction. It has been suggested that abnormalities in LV diastolic function may actually precede LV systolic dysfunction, and therefore, serve as an early and sensitive marker of ischemia. This study aims to find improvement of diastolic function after percutaneous coronary intervention (PCI) in patients with stable or unstable angina.
Methods:
In this single-center hospital-based study, we enrolled 309 patients with either stable or unstable CAD and with normal systolic function who underwent successful PCI. Two-dimensional transthoracic echocardiography was performed at baseline (before PCI) and repeated 48 h after PCI. LV diastolic parameters were compared before and after PCI using paired samples
t
-test results.
Results:
Mean age of study population was 56.65 ± 9.65 years. Majority of patients were male (63%). There was significant increase in mitral E-wave velocity (68.39 ± 17.52 cm/s vs. 71.64 ± 18.23 cm/s), E/A ratio (0.85 ± 0.29 vs. 0.89 ± 0.32), and early diastolic mitral annular motion (e') (7.02 ± 0.89 cm/s vs. 8.45 ± 0.86 cm/s) following PCI (
P
< 0.0001). Left atrial volume index (22.53 ± 4.43 vs. 20.81 ± 4.14), tricuspid jet velocity (0.91 ± 0.57 m/s vs. 0.76 ± 0.67 m/s), and E/e' ratio (10.03 ± 3.5 vs. 8.62 ± 2.61) decreased significantly following PCI (
P
< 0.001).
Conclusion:
This study suggests that LV diastolic filling pattern is modified significantly as early as 48 h after successful PCI. Improvement in impaired relaxation appears to be most likely explanation for these changes. PCI may be potential therapeutic target to improve diastolic function in patients with CAD.

Transcatheter mitral valve repair to treat postmyocardial infarction papillary muscle rupture
Ahmad Hayek, Daniel Grinberg, François Derimay, Thomas Bochaton
April-June 2021, 31(2):104-106
DOI
:10.4103/jcecho.jcecho_137_20
A 75-year-old man was admitted to the emergency department for a late-presenting myocardial infarction. The coronary angiography revealed a thrombotic occlusion of the circumflex artery. He presented a rapid hemodynamic and respiratory deterioration as a result of a severe mitral regurgitation with a flail anterior leaflet due to a partial tear of the medial papillary muscle (PM). Given the patient's comorbidities, a percutaneous mitral valve repair with two-dimensional (2D)/3D transesophageal echocardiography was performed, deploying two MitraClips. MitraClip implantation may be considered in an acute setting of PM tear as an alternative for surgical treatment in selected patients.

Pentraxin-3 is associated with adverse diastolic remodeling in patients with st-elevation myocardial infarction after successful reperfusion by primary percutaneous intervention
Mustafa Umut Somuncu, Fatih Pasa Tatar, Nail Guven Serbest, Begum Uygur, Ali Riza Demir
April-June 2021, 31(2):77-84
DOI
:10.4103/jcecho.jcecho_116_20
Background:
Determinants of adverse diastolic remodeling in ST-elevated myocardial infarction (STEMI) after successful revascularization are not well established. Besides, the relationship between Pentraxin-3 (PTX-3) and diastolic function deterioration is unknown. This study hypothesizes that PTX-3 level would be associated with diastolic remodeling.
Materials
and
Methods:
Ninety-eight STEMI patients were included in our study. Echocardiography was performed before and 12–18 weeks after discharge. Two groups were generated according to the PTX-3 value, and the follow-up/baseline echocardiographic parameters were compared. Diastolic adverse remodeling was accepted as a persistent restrictive filling pattern or an increase in at least one grade of diastolic dysfunction. The independent predictors of diastolic adverse remodeling were investigated.
Results:
Adverse diastolic remodeling was detected in 19.3% of patients. High left ventricular mass index (odds ratio [OR]: 1.096, confidence interval [CI] 95%: 1.023–1.174,
P
= 0.009), high PTX-3 (OR: 1.005, CI 95%: 1.001–1.009,
P
= 0.024), and failing to achieve thrombolysis in myocardial infarction flow 3 after percutaneous coronary intervention (OR: 6.196, CI 95%: 1.370–28.023,
P
= 0.005) were determined as independent predictors of adverse diastolic remodeling. The ratio of follow-up/baseline left atrial volume index was higher in the high PTX-3 group (1.15 vs. 1.05,
P
= 0.029). Moreover, being in the high PTX-3 group predicted adverse diastolic remodeling at 7.4 times.
Conclusion:
Higher PTX-3 level is associated with adverse diastolic remodeling in STEMI patients.

Pneumonia is the most commonly described manifestation of
Legionella pneumophila
infection (legionellosis), and extrapulmonary manifestations are uncommon. There are a few descriptions of acute myocarditis associated with legionellosis. We present a case of acute myocarditis in a patient admitted for legionellosis with multisystemic involvement (lung, heart, and kidney). Left ventricular (LV) dysfunction was documented by cardiac magnetic resonance (CMR) and two-dimensional speckle-tracking echocardiography; layer-specific strain analyses were performed, which allowed to differentiate subendocardial or subepicardial contractile impairment. Layer-specific strain analyses by echocardiography demonstrated impairment of subepicardial deformation in the inferolateral wall, which mirrored CMR findings, showing late gadolinium enhancement in the subepicardium of the same LV segments. After initiation of appropriate antibiotic therapy with levofloxacin, LV systolic function rapidly improved as assessed by both CMR and strain analyses, with concomitant normalization of both clinical and biochemical abnormalities. The basic mechanisms of myocardial involvement during legionellosis are unclear; we discussed our findings according to the limited available evidence.

A mediastinal hematoma after the bentall operation detected by transthoracic echocardiography
Ali Hosseinsabet, Jamshid Bagheri, Shapoor Shirani
April-June 2021, 31(2):96-97
DOI
:10.4103/jcecho.jcecho_117_20
A round, well-defined mass was incidentally detected at follow-up transthoracic echocardiography in an asymptomatic 36-year-old man with a history of Bentall operation 8 months earlier. Computed tomography angiography of the aorta demonstrated a mediastinal hematoma below the pulmonary artery in the mid-mediastinum. Although mediastinal hematomas are hard to detect after cardiac surgery via transthoracic echocardiography, the probable presence of this complication should be kept in mind during echocardiography.

A giant left circumflex artery aneurysm with thrombosis formation presenting as a left atrioventricular groove mass
Reza Mohseni Badalabadi, Ali Hosseinsabet, Abbas Salehi Omran, Shapoor Shirani

DOI

A coronary artery aneurysm is defined as the dilation of a coronary artery segment that is 1.5-fold the diameter of the neighboring normal segments. A patient with a history of aortic valve replacement and coronary artery bypass graft surgery, transthoracic echocardiography revealed a large mass with an echolucent center in the left atrioventricular groove. Transesophageal echocardiography showed that the left atrial appendage was free of thrombosis, and there was a mass with an echolucent center beneath the left atrial appendage, suggestive of aneurysmal dilation in the left circumflex artery with thrombosis formation Coronary artery computed tomography angiography confirmed this finding. In patients with or without a history of coronary aneurysms, the presence of a mass in the atrioventricular groove on echocardiography should alert clinicians about the presence of a coronary artery aneurysm with thrombosis formation as a probable etiology.

Cardiac myxomas are the most common primary intracardiac tumors in adults. Although benign from a histopathological point of view, they can be life-threatening for the patient. We present a case of an unusually giant left atrial myxoma causing mitral valve obstruction and pulmonary hypertension successfully treated with surgical resection. Our patient was a 54-year-old woman who presented to our emergency complaining of progressive dyspnea of about 1 month duration. On cardiovascular examination, we found crackling rales at both lung bases and a diastolic murmur in the mitral focus. Transthoracic echocardiography revealed a giant mass in the left atrium connected to the interatrial septum and extended into the left ventricle during diastole which caused obstruction of the left ventricular inflow tract and a pulmonary hypertension. The patient underwent a median sternotomy with the removal of left atrial mass and patch closure of the interatrial septum. Histopathological examination confirmed the diagnosis of myxoma. One week later, the patient was discharged without any complications. Giant left atrial myxoma although a benign mass, can induce dramatic symptoms and be life-threatening. In case of suspicion, it must be diagnosed early by transthoracic echocardiography and urgently managed by surgical removal.

Nephroblastoma with right atrial extension
Ejiroghene Martha Umuerri, Helen Kesiena Odion-Obomhense

:10.4103/jcecho.jcecho_113_20
Two-dimensional echocardiography is useful in the diagnosis of cardiac masses, including tumors. Cardiac metastasis of nephroblastoma heralds a worse prognosis. This 4-year-old child presented with clinical and radiological features suggestive of nephroblastoma. She had intracaval spread of the tumor to the right atrium. The cardiac metastasis was initially missed as echocardiography was not part of the routine workup for the patient as she had no clinical features suggestive of cardiac disease. Although cardiac metastasis of nephroblastoma is rare, we recommend routine transthoracic echocardiography for all patients irrespective of the presence of cardiac symptoms and signs.

“Pac-man heart” and mitral valve prolapse: An unreported liaison
Angela Pamela Peluso, Ivana Iesu, Gennaro Provenza, Rodolfo Citro
April-June 2021, 31(2):113-115
DOI
:10.4103/jcecho.jcecho_8_21
A 50-year-old man accessed the echo laboratory for dyspnea. His medical history was unremarkable. Transthoracic two-dimensional echocardiogram showed a posterior leaflet of the mitral valve prolapse associated with eccentric regurgitant jet. An excavation of the medium interventricular septum, in the absence of left–right interventricular shunt, was detected as an incidental finding and considered as partial ventricular septum defect. Owing to the absence of acute myocardial infarction and thrombolysis in patient's medical history, this finding has been considered “pac-man heart” of the congenital origin. Of note, the association of this deformity with mitral valve prolapse is reported for the first time.

Noninvasive diagnostic approach to a rare variant of takotsubo syndrome: From ESC guidelines to real world
Tommaso D’Angelo, Maria Ludovica Carerj, Concetta Zito, Silvio Mazziotti
April-June 2021, 31(2):119-121
DOI
:10.4103/jcecho.jcecho_28_21
Takotsubo syndrome is found in about 5%–6% of patients presenting with suspected ST-elevation myocardial infarction. Coronary angiography with left ventriculography is currently considered the modality of choice for the diagnosis. However, improvements of noninvasive diagnostic techniques have been allowing for definite assessment of ventricular function and anatomy. In this setting, the combined use of coronary computed tomography angiography and cardiac magnetic resonance may play a pivotal role for a complete noninvasive diagnosis and management of these patients. We present a case of a 52-year-old woman who presented to our department complaining chest pain and showing left ventricular systolic dysfunction, electrocardiography abnormalities, and mild elevation of cardiac-specific serum enzymes.
