Cardiac Diagnosis

Prenatal ultrasound screening has allowed for the detection of in utero cardiac abnormalities. Specifically, distinction is possible between ventricular diverticula and aneurysms, which is important because each condition has a different clinical outcome. We report the case of a 35-year-old, gravida 1, para 1 woman, with no significant past medical history, who underwent routine prenatal ultrasound screening at 32 weeks’ gestation. A four-chamber ultrasound of the fetal heart combined with M-mode echocardiography showed abnormal dilatation of the right ventricular chamber measuring 2.2 cm × 1.0 cm but with normal contractility. Delivery was performed at full term by cesarean section, and a right ventricular diverticulum was confirmed by postnatal cardiac computed tomography. The baby developed normally with no cardiac sequelae during followup. This case demonstrates the importance of making a correct diagnosis of ventricular diverticula by prenatal ultrasound when abnormal dilatation of the fetal ventricle is identified during routine screening. Because evaluating the wall contractility by M-mode ultrasound leads to evaluating whether it has the myocardium, we conclude that M-mode echocardiography is effective for the purpose of prenatal cardiac diagnosis and can distinguish between ventricular aneurysms and functioning ventricular diverticula.

A 43-year-old woman presented to the emergency room with a sustained ventricular tachycardia (VT). ECG showed a QRS in left bundle branch block morphology with inferior axis. Echocardiography, ventricular angiography, and cardiac magnetic resonance imaging (CMRI) revealed a normal right ventricle and a left ventricular diverticulum. Electrophysiology studies with epicardial voltage mapping identified a large fibrotic area in the inferolateral layer of the right ventricular wall and a small area of fibrotic tissue at the anterior right ventricular outflow tract. VT ablation was successfully performed with combined epicardial and endocardial approaches.

Annuloaortic ectasia is a relatively rare diagnosis. Herein, we report an unusual case of an annuloaortic ectasia with asymmetric dilatation of the right coronary bulb mimicking a membranous ventricular septal defect (VSD) with Eisenmenger reaction by transthoracic echocardiography. Aortic angiography showed a dilated aortic root and moderate aortic regurgitation. Right cardiac catheterization, on the other hand, exhibited normal pulmonary artery blood pressure and normal pulmonary resistance, whereas normal venous gas values were measured throughout the caval vein and the right atrium, excluding relevant left-right shunting. Further diagnostic workup by cardiac computed tomography angiography (CCTA) unambiguously illustrated the asymmetric geometry of the ectatic aortic cusp and root causing compression of the right heart and of the right ventricular (RV) outflow tract. After review of echocardiographic acquisitions, the blood flow detected between the left and right ventricles (mimicking VSD) was interpreted as turbulent inflow from the left ventricle into the ectatic right coronary cusp. Furthermore, elevated pulmonary artery blood pressure measured by echocardiography was attributed to “functional pulmonary stenosis” due to compression of the RV outflow tract by the aorta, as demonstrated by CCTA.

Objectives. The case of the right ventriclar aneurysm is presented. Pregnancy was terminated due to medical conditions. Autopsy was performed. Materials and Results. On carrying out the fetal ultrasound, a fingerlike protrusion with a wide neck, measuring 4  4 mm, was found in the right ventricular apex. There was pericardial effusion. The aneurysm wall was represented by the ectopic thymus tissue. Conclusions. Aneurysm and diverticulum of the fetal heart are dangerous disorders. The rate of fetal complications during pregnancy is high. The diagnosis of aneurysm/diverticulum may be made in the prenatal period. The prognosis of the survivors significantly differs between patients. Infants with no change in size of aneurysm/diverticulum had a normal development and no adverse events during follow-up. It is important to remember about different aetiology of fetal anomalies.

Background. Right ventricular volumes (RVV) and ejection fraction (RVEF) measurements are challenging due to the complex shape of the right ventricle (RV). Current methods are tedious and have limited ability to take into account the base of the RV and right ventricular outflow tract. Novel semi-automated border detection software, RV analysis (RVA) was recently developed (TomTec) to overcome these limitations. Our goal was to determine whether there are inter-modality differences between real-time 3D echocardiographic (RT3DE), cardiac computed tomography (CCT) and cardiac magnetic resonance (CMR) data using the same RVA. Methods. We acquired transthoracic RT3DE images of the RV (Philips iE33 w/X4 probe) from the apical window using a full-volume mode in 12 patients referred for CMR imaging (1.5T Siemens scanner) and CCT (Toshiba) on the same day. CMR and CCT images were obtained in a stack of short-axis slices from RV base to apex, four-chamber and coronal views, and reformatted to obtain Cartesian volume data. All three types of images were analyzed to obtain end-systolic and end-diastolic volumes (ESV, EDV) and EF using RV analysis software (RVA). RT3DE and CCT were compared to CMR values as the reference standard, using linear regression and Bland-Altman analyses. Results. Analysis of RT3DE, CCT and CMR data were feasible in all patients. RT3DE and CCT RVV and RVEF correlated well with CMR (Table). CCT overestimated RVV whereas RT3DE underestimated RVV. Both CCT and RT3DE slightly underestimated RVEF compared to CMR. Conclusion. This new technique for volumetric RV surface detection applied to RT3DE and CCT data provides accurate RVV and RVEF measurements in agreement with CMR.

AbstractObjectivesTo evaluate 24-segment fractional shortening (FS) of the fetal heart using FetalHQ by speckle-tracking regarding reproducibility and the change with advancing gestation.MethodsEighty-one pregnant women at 18–21 + 6 and 28–31 + 6 weeks of gestation were studied using FetalHQ with the speckle-tracking technique to calculate 24-segment FS of left and right ventricles. Intra- and inter-class correlation coefficients and intra- and inter-observer agreements of measurements for FS were assessed in each segment.ResultsWith respect to intra-observer reproducibility, all FS values showed correlations between 0.575 and 0.862 for the left ventricle, with good intra-observer agreements except for left ventricular segments 14–24. Right ventricular FS values showed correlations between 0.334 and 0.685, with good intra-observer agreements. With respect to inter-observer reproducibility, all FS values showed correlations between 0.491 and 0.801 for the left ventricle, with good intra-observer agreements except for left ventricular segments 16–22. Right ventricular FS values showed correlations between 0.375 and 0.575, with good inter-observer agreements. There were significant differences in the mean FS values in the basal segment (segments 1–5) of the left ventricle between 18 and 21 + 6 and 28–31 + 6 weeks of gestation (p<0.05), whereas there were significant differences in all mean FS values in the right ventricle between both gestational ages (p<0.05).ConclusionsThese results suggest that the reproducibility of the 24-segment FS of the fetal heart using FetalHQ is fair. However, there may be significant differences in FS values with advancing gestational age, especially for the right ventricle.

We report the case of an 18 year old man who unexpectedly died of healing myocarditis. His heart was hypertrophied with multifocal fibrosis which can be a common histological feature of primary and secondary cardiomyopathy as well as the healing phase of myocarditis. However, the pattern of myocardial fibrosis, inflammation with myonecrosis, sparing of the right ventricular myocardium, and cardiomyocytes features in the remaining areas of the heart were considered as the key elements in determining a diagnosis of myocarditis. This case illustrates that meticulous histologic examination and the analysis of the histologic findings in the hypertrophied heart with multifocal fibrosis can be helpful to make a correct diagnosis.
