Review
This review includes 36 studies of transthoracic real-time three-dimensional echocardiography (RT3DE) in animals. Most of these studies concern cardiac chamber quantification of the left atrium and left ventricle, in dogs. Comparisons of RT3DE and different two-dimensional echocardiographic (2DE) methods have been reported in dogs with myxomatous mitral valve disease (MMVD), dilated cardiomyopathy, and in healthy control dogs. Comparisons of RT3DE and standard reference methods have been reported in healthy control dogs. In dogs with MMVD, volumetric RT3DE measurements of left atrium do not appear to provide superior prognostic value compared with 2DE methods using Simpson's method of discs in dogs with MMVD. The major advantages of RT3DE compared to 2DE include improvements in visualization of the complex morphology of the mitral valve, the estimation of mitral valve regurgitation, and improved visualization of complex congenital cardiac abnormalities.

The recent special issue of the devoted to hypoplastic left heart syndrome, and its related anomalies, contained significant information of great clinical relevance. Very little attention, however, was devoted to the integrity of ventricular septum as providing a criterion to distinguish between the phenotypes to be included within the syndrome, as opposed to the related anomalies. In this commentary, we summarize the evidence in support of the notion that the phenotypes to be included within the syndrome can be interpreted on the basis of an acquired disease of fetal life. We suggest that it is the integrity of the ventricular septum that provided the major criterion for the distinction between the lesions making up the syndrome and the related anomalies. The subsets of lesions to be included within the syndrome can then be recognized in terms of the time, subsequent to the closure of the embryonic interventricular communication, at which the left ventricle ceased its growth relative to the remainder of the cardiac components. On this basis, it is possible to recognize the combinations of aortic and mitral atresia, mitral stenosis with aortic atresia, combined mitral and aortic stenosis, and hypoplasia of the left ventricle with commensurate hypoplasia of the aortic and mitral valves; the latter combination now recognized as the hypoplastic left heart complex.

Echocardiography (Mount Kisco, N.Y.) Jul 2023The high complexity of mitral valve anatomy and function in mitral valve prolapse (MVP) is not yet fully understood.
BACKGROUND
The high complexity of mitral valve anatomy and function in mitral valve prolapse (MVP) is not yet fully understood.
OBJECTIVE
The purpose of this study was to analyze each part of the mitral valve apparatus in children to determine its impact on the presence of MVP and to assess the interaction between the coaptation length (CL) and mitral regurgitation severity.
METHODS
We prospectively analyzed transthoracic echocardiograms of 60 patients with MVP (mean age 9.8 ± 3.1 years). We compared these patients with 60 control patients without disease. We determined length of leaflets, chordal length, tenting area, coaptation CL, the intrapapillary muscle distance (IPMD) and relation between CL and severity of mitral regurgitation (MR).
RESULTS
For patients with MVP, the posterior mitral leaflet (PML) was significantly enlarged 13.9 ± 4.1 mm versus 10.7 ± 3.5 mm (p < .01), the primary chordal length was significantly decreased 15.4 ± 3.61 mm versus 17.6 ± 3.8 mm (p < .02), and IPMD was significantly greater 18.1 ± 2.7 mm versus 16.6 ± 4.3 mm (p < .03). The difference between CL for both the anterior and posterior mitral leaflets correlated positively with MR (r = .249, p < .05). A greater than 4 mm CL correlated with at least MR (sensitivity 100%, specificity 72%) and greater than 5 mm correlated with at least moderate MR (sensitivity 100%, specificity 60%).
CONCLUSION
The majority of pediatric patients with mitral valve prolapse have structural abnormalities that are defined well by echocardiography. In addition to the presence of prolapse and regurgitation, routine assessment of leaflet length, thickness, chordal length and papillary muscle distance is fundamental for patients with MVP.

INTRODUCTION
Prevalence estimates place maternal heart illness anywhere from 0.3 to 3.5 percent. Up to 20.5% of all maternal deaths of non-obstetrical cause are attributable to cardiovascular disease.
AIM
The aim of the study was the management of patients with the multidisciplinary approach to maternal cardiovascular disease and its influence on maternal and fetal outcomes in a tertiary care centre.
OBJECTIVES
1. To find out the prevalence and spectrum of heart disease in Pregnancy. 2. To find out the outcome of pregnancy with heart disease in a tertiary care centre.
MATERIALS AND METHODS
This prospective study of one year was done on pregnant with heart disease coming to the Obstetrics and Gynaecology department in collaboration with the cardiology department of IGIMS, Patna. A study was done on 65 pregnant with heart disease between the age group 20 to 35 years were compared to a control group of 65 pregnant women who were hospitalised during the same time period but did not have heart disease. All the pregnant women with heart disease were included in this study. Patients with medical disorders like Kidney disease, Liver disease, Pulmonary Disease, Diabetes Mellitus were excluded from the study. We used IBM's SPSS v23 to analyse the collected data.
RESULT
Prevalence of heart disease in pregnancy was 5.8% in present study and mostly of RHD (62.5%), followed by corrected CHD (12.5%) and CHD (10.9%). Patients of NYHA Class I and II (58.5%), Class III (26.2%), and Class IV (15.4%). The mitral valve was most often impacted by RHD (35.3% of all cases), followed by the tricuspid valve (15.0%). Eight (1.1%) people had cardiac surgery for therapeutic reasons. Six percent of all corrective surgeries included closing an atrial septal defect (ASD). The most common kind of congenital abnormality was a ventricular septal defect (VSD, 3%), followed by atrial septal defect (ASD, 1.5%) and pulmonary ductal atresia (PDA, 1.5%). Patients with heart disease had a higher rate of MTP, emergency LSCS and instrumental births than the controls. Deaths during pregnancy were 4 (6.2%) with cardiac disease and no maternal mortality in control group and all belonged to NYHA Class 4 were anaemic. In patients with a left ventricular ejection fraction of 45% or below, death was high. Two women died intrapartum from RHD, and two died postpartum from Peripartum cardiomyopathy. There were significantly more incidences of low-birth-weight infants (36.4%) compared to the control group (p = 0.001). Cases had a statistically significant greater frequency of obstetric problems, as well as an increased risk of developing anaemia, hypertension, hypothyroidism, cholestasis, FGR, and GDM (p-value 0.017). Multiparity, severe valvular lesion, NYHA function class III or IV, arrhythmia, and low ejection fraction were associated with poor maternal outcome in the current study.
CONCLUSION
Maternal morbidity and mortality due to heart disease can be reduced appreciably by antenatal care, early diagnosis, and management with the help of cardiologists and surgery in selected cases.

Review
Left ventricular (LV) non-compaction (LVNC) is a rare genetic cardiomyopathy due to abnormal intra-uterine arrest of compaction of the myocardial fibers during endomyocardial embryogenesis. Due to the partial or complete absence of LV compaction, the structure of the LV wall shows characteristic abnormalities, including a thin compacted epicardium and a thick non-compacted endocardium with prominent trabeculations and deep intertrabecular recesses. LVNC is frequently associated with chronic heart failure, life-threatening ventricular arrhythmias, and systemic embolic events. According to recent findings, in the presence of LVNC, dysfunctional LV proved to be associated with left atrial volumetric and functional abnormalities and consequential dilated and functionally impaired mitral annulus, partly explaining the higher prevalence of regurgitation. Although the non-compaction process morphologically affects only the LV, signs of remodeling of the right heart were also detected. Moreover, dilation and stiffening of the aorta were present. The aim of the present detailed review was to summarize findings regarding changes in cardiac mechanics, valvular abnormalities, and vascular remodeling detected in patients with LVNC.

BACKGROUND
Mitral stenosis/aortic atresia (MS/AA) has been reported as a high-risk variant of hypoplastic left heart syndrome (HLHS), potentially related to ventriculocoronary connections (VCCs) or endocardial fibroelastosis (EFE) and myocardial hypoperfusion. We aimed to identify echocardiographic and clinical factors associated with early death or transplant in this group.
METHODS
Patients with HLHS MS/AA treated at our center between 2000 and 2020 were included. Pre-stage I palliation echocardiograms were reviewed. Certain imaging factors, such as determination of VCC, EFE, and measurement of tricuspid annular plane systolic excursion were measured from retrospective review of preoperative images; others were derived from clinical reports. Groups were compared according to primary outcome of death or transplant prior to stage II palliation.
RESULTS
Of 141 patients included, 39 (27.7%) experienced a primary outcome. Ventriculocoronary connections were identified in 103 (73.0%) patients and EFE in 95 (67.4%) patients. Among imaging variables, smaller ascending aorta size (median, 2.2 [interquartile range (IQR) 1.7-2.8] vs 2.6 [2.2-3.4] mm, P = .01) was associated with primary outcome. There was similar frequency of VCC (74.4% vs 72.5%, P = .83), EFE (59.0% vs 72.5%, P = .19), moderate or greater tricuspid regurgitation (5.1% vs 5.9%, P = 1.00), and similar right ventricular systolic function (indexed tricuspid annular plane systolic excursion 32.5 ± 7.3 vs 31.4 ± 7.2 mm/m, P = .47) in the primary outcome group compared to other patients. Clinical factors associated with primary outcome included lower birth weight (mean, 2.8 ± SD 0.8 vs 3.3 ± 0.5 kg, P = .0003), gestational age <37 weeks (31.6% vs 4.9%, P < .0001), longer cardiopulmonary bypass time (median, 112 [IQR, 93-162] vs 82 [71-119] minutes, P = .001), longer intensive care unit length of stay (median, 19 [IQR, 10-30] vs 10 [7-15] days, P = .001), and extracorporeal membrane oxygenation following stage I palliation (43.6% vs 8.8%, P < .0001). Presence of VCCs and EFE was not associated with death or transplant after controlling for birth weight and era of stage I palliation.
CONCLUSIONS
In one of the largest reported single-center cohorts of HLHS MS/AA, there were few pre-stage I palliation imaging characteristics associated with primary outcome. Imaging findings evaluated in this study, including the presence of VCC and/or EFE as determined using highly sensitive echocardiogram criteria, should not preclude intervention, although impact on long-term outcomes requires further evaluation.

INTRODUCTION
To echocardiographically evaluate a large number of apparently healthy Czechoslovakian wolfdogs (CWDs) to identify possible subclinical cardiac abnormalities and to generate reference intervals.
ANIMALS
One-hundred and seventeen apparently healthy client-owned CWDs.
MATERIALS AND METHODS
Standard two-dimensional, M-mode, and Doppler echocardiographic measurements were obtained on non-sedated, manually restrained standing dogs. Animals with no relevant echocardiographic abnormalities were used to generate reference intervals. Echocardiographic variables were compared between males and females and between dogs with and without mitral regurgitation (MR).
RESULTS AND DISCUSSION
Among the 117 CWDs, 103 dogs were used to generate reference intervals. The 14 dogs with abnormalities had more than trivial MR (12 dogs), subaortic stenosis (one dog), and equivocal subaortic stenosis (one dog). The 44 males were heavier than 59 females (P<0.001) and had a larger maximum left atrial dimension (P=0.015), left ventricular internal dimension at end-diastole (P<0.001) and systole (P<0.001), and thicker interventricular septum thickness at end-diastole (P=0.016). A positive linear correlation was identified between bodyweight and aortic root and left atrial diameters and left ventricular dimensions and between age and aortic root and left atrial diameter and peak late transmitral flow velocity. A negative linear correlation was identified between age and peak early transmitral flow velocity and the ratio between peak early and late transmitral flow velocities. No differences in echocardiographic-derived cardiac dimensions were detected between healthy dogs and dogs with more than trivial MR.
CONCLUSIONS
In this population of CWDs, subclinical cardiac abnormalities were uncommon, and they were mainly classified as MR.

AIM
To explore left ventricular structural/functional abnormalities in preeclampsia patients by using multimodal echocardiography and to analyze the cardiac impact in preeclampsia subtypes.
METHODS
A total of 103 individuals, including 64 preeclampsia patients and 39 healthy pregnant women were recruited for this study from 2019 to 2021. There were 34 patients with preeclampsia with severe features (SPE) patients and 30 with preeclampsia with nonsevere features (NSPE), including 9 with early-onset NSPE (EO-NSPE) patients, 27 early-onset SPE (EO-SPE) patients, 21 later-onset NSPE (LO-NSPE), and 7 with later-onset SPE (LO-SPE). All patients underwent multimodal echocardiography before treatment, including two-dimensional, Doppler, and speckle-tracking echocardiography, to evaluate left ventricular structure/function. Analysis of variance was used to determine statistical significance across groups.
RESULTS
EO-SPE patients showed decreased left ventricular ejection fractions, peak longitudinal systolic strain at apical four-chambers, peak circumferential, and radial systolic strain at the apical and mitral annular plane systolic excursion (MAPSE), and increased mitral regurgitation compared to other preeclampsia patients. Compared to LO-NSPE and EO-SPE patients, LO-SPE patients showed increased left ventricular mass indexed to height and early diastolic left ventricular diastolic filling/mitral annular velocity, and decreased MAPSE and early/late diastolic mitral annular velocity.
CONCLUSION
EO-SPE patients were characterized by left ventricular injury and systolic function reduced. LO-SPE patients were characterized by left ventricular hypertrophy and reduced diastolic function. Multimodal echocardiography can detect myocardial injury in PE patients at an early stage.

INTRODUCTION
The anomalous aortic origin of the coronary arteries has an estimated prevalence of 0.02-5.7%. It can be associated with sudden death when it has an interarterial or intramural pathway or be damaged during interventions on the mitral, pulmonary and/or aortic annulus or percutaneous closure of an interatrial septal defect.
OBJECTIVE
To identify these patients by imaging techniques such as transthoracic color Doppler echocardiography (TTE), computed tomography (CT) multislice angiography or coronary angiography.
METHODS
The imaging techniques used for the detection of coronary anomalies were TTE, multislice coronary angiography or coronary angiography according to what is generally accepted.
RESULTS
Fifteen patients were identified; in 12 of them the suspicion was due to TTE and in the remaining 3, CT multislice angiography was diagnostic. The circumflex artery was the coronary artery most involved, associated or not with another coronary anomaly (12/15 patients) and in the other three cases, the anomalous coronary artery had an interarterial course, with the right coronary arteries and the anterior descending coronary arteries being involved.
CONCLUSIONS
The under diagnosis by TTE of coronary artery abnormalities may be due to the difficulty of visualization that is accentuated with age. Their detection is crucial because they can both, lead to sudden death associated with an intramural and/or interarterial pathway and complicate an interventional procedure on the interatrial septum or within the mitral, pulmonary and/or aortic rings.

Review
Hypereosinophilic syndrome (HES) is considered to be a rare myeloproliferative disease that is characterized by persistent eosinophilia with associated multiple-organ damage. The heart is often involved in HES, representing a major cause of morbidity and mortality. HES is a heterogeneous group of disorders; the majority of the cases are idiopathic. Summarizing the findings regarding myocardial, valvular, and vascular abnormalities in a series of patients with HES, most studies found normal left ventricular (LV) volumes with reduced LV global longitudinal strain and LV apical rotation and twist in HES cases, accompanied by increased left atrial (LA) volumes and stroke volumes, reduced peak LA circumferential strain (representing systolic abnormalities), and mitral annular dilation and functional deterioration. Regarding the right heart, preserved right ventricular volumes and functional properties, increased right atrial volumes, mild RA functional abnormalities, and dilated tricuspid annular dimensions without functional impairment could be seen in these studies. Aortic and pulmonary valves showed no specific disease-related alterations. Vascular abnormalities included increased aortic stiffness without dilation of the aorta and pulmonary hypertension in some cases. These results suggest disease-specific but relatively mild myocardial, valvular, and vascular abnormalities in HES. The present review aimed to summarize the available clinical data about cardiac mechanics and valvular and vascular abnormalities in a series of patients with HES.
