Three‐Dimensional Echocardiography and 2D‐3D Speckle‐Tracking Imaging in Chronic Pulmonary Hypertension: Diagnostic Accuracy in Detecting Hemodynamic Signs of Right Ventricular (RV) Failure

Background Our aim was to compare three‐dimensional (3D) and 2D and 3D speckle‐tracking (2D‐STE, 3D‐STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH), and investigate whether these techniques could result in better correlation with hemodynamic variables indicative of heart failure. Methods and Results Seventy‐three adult patients (mean age, 53±13 years; 44% male) with chronic PH of different etiologies were studied by echocardiography and cardiac catheterization (25 precapillary PH from pulmonary arterial hypertension, 23 obstructive pulmonary heart disease, and 23 postcapillary PH from mitral regurgitation). Thirty healthy subjects (mean age, 54±15 years; 43% male) served as controls. Standard 2D measurements (RV–fractional area change–tricuspid annular plane systolic excursion) and mitral and tricuspid tissue Doppler annular velocities were obtained. RV 3D volumes and global and regional ejection fraction (3D‐RVEF) were determined. RV strains were calculated by 2D‐STE and 3D‐STE. RV 3D global‐free‐wall longitudinal strain (3DGFW‐RVLS), 2D global‐free‐wall longitudinal strain (GFW‐RVLS), apical‐free‐wall longitudinal strain, basal‐free‐wall longitudinal strain, and 3D‐RVEF were lower in patients with precapillary PH (P<0.0001) and postcapillary PH (P<0.01) compared to controls. 3DGFW‐RVLS (hazard ratio 4.6, 95% CI 2.79 to 8.38, P=0.004) and 3D‐RVEF (hazard ratio 5.3, 95% CI 2.85 to 9.89, P=0.002) were independent predictors of mortality. Receiver operating characteristic curves showed that the thresholds offering an adequate compromise between sensitivity and specificity for detecting hemodynamic signs of RV failure were 39% for 3D‐RVEF (AUC 0.89), −17% for 3DGFW‐RVLS (AUC 0.88), −18% for GFW‐RVLS (AUC 0.88), −16% for apical‐free‐wall longitudinal strain (AUC 0.85), 16 mm for tricuspid annular plane systolic excursion (AUC 0.67), and 38% for RV‐FAC (AUC 0.62). Conclusions In chronic PH, 3D, 2D‐STE and 3D‐STE parameters indicate global and regional RV dysfunction that is associated with RV failure hemodynamics better than conventional echo indices.

Right ventricular function in acute pulmonary embolism: a combined assessment by three-dimensional and speckle-tracking echocardiography.

BACKGROUND The aim of this study was to assess changes in right ventricular (RV) parameters determined by three-dimensional (3D) echocardiography and speckle-tracking echocardiography in patients with acute pulmonary embolism and RV dysfunction without systemic hypotension (submassive pulmonary embolism). METHODS Sixty-six patients were prospectively studied at the onset of the acute episode and after median follow-up periods of 30 days and 6 months. Sixty-six controls were selected. RV fractional area change, tricuspid annular plane systolic excursion, and myocardial performance index were determined. RV systolic pressure was assessed using continuous-wave Doppler echocardiography. Three-dimensional RV ejection fraction (RVEF) was calculated. Two-dimensional peak systolic RV longitudinal strain (RVLS) was measured in the basal free wall, mid free wall (MFW), and apical free wall and the septum. RESULTS Tricuspid annular plane systolic excursion and fractional area change were smaller and myocardial performance index was larger compared with controls (P < .05). Global RVLS (P < .05), MFW RVLS (P < .001), and 3D RVEF (P < .001) were lower in patients with pulmonary embolism than in controls. There was earlier reversal of MFW RVLS values on 30-day follow-up and longer reversal of 3D RVEF and RV systolic pressure values at 6-month follow-up. Receiver operating characteristic curve analysis showed that changes in 3D RVEF and MFW RVLS were the most sensitive predictors of adverse events. By multivariate analysis, RV systolic pressure (P = .007), MFW RVLS (P = .002), and 3D RVEF (P = .001) were independently associated with adverse outcomes. CONCLUSIONS Acute submassive pulmonary embolism has a significant impact on RV function as assessed by 3D echocardiography and speckle-tracking echocardiography. Decreases in MFW RVLS and 3D RVEF may persist during short-term and long-term follow-up and correlate with unfavorable outcomes.

The role of intraoperative transoesophageal echocardiography in the diagnosis and management of a rare multiple fibroelastoma of aortic valve: a case report and review of literature

Papillary fibroelastoma is the third most common primary tumour of the heart that usually involves the cardiac valves. Multiple papillary fibroelastomas are extremely rare. We report a case with multiple valve papillary fibroelastoma which was identified only by intraoperative transoesophageal echocardiography. The patient complained of atypical chest pains. She was affected by coronary artery disease and had previously had a myocardial infarct. This finding dictated a change in the operative approach. The aortic valve resection was performed in addition to coronary revascularization. If the intraoperative transoesophageal echocardiography was not performed, our patient would have had just coronary artery bypass graft surgery, probably without solving the symptoms. Furthermore, in future she would have undergone another cardiac operation for resection of aortic masses and valve replacement. The intraoperative use of Transoesophageal Echocardiography improves the diagnosis and the management of all cardiac surgical patients.

Biventricular assessment of light-chain amyloidosis using 3D speckle tracking echocardiography: Differentiation from other forms of myocardial hypertrophy

BACKGROUND Given that in patients with cardiac amyloidosis (CA), deposition of amyloid protein is not restricted to the left ventricular (LV) myocardium, it can be hypothesized that the diagnostic value of deformation mechanics would be enhanced by considering right ventricular (RV) strain measures. The aim of the present study was to examine the potential utility of left ventricular (LV) and right ventricular (RV) deformation and rotational parameters derived from three-dimensional speckle-tracking echocardiograph (3DSTE) to diagnose cardiac amyloidosis and differentiate this disease from other forms of myocardial hypertrophy. METHODS Twenty-three patients with biopsy-proven light-chain (AL) amyloidosis, 23 patients with systemic arterial hypertension (HTN), 23 patients with hypertrophic cardiomyopathy (HCM), 23 athletes and 23 normal controls were prospectively studied by conventional echocardiography and 3DSTE. LV longitudinal strain (LV LS), LV circumferential strain (LV CS), RV global longitudinal strain and RV free-wall longitudinal strain (RV FW LS) were obtained by 3DSTE, as well as LV rotation and rotational velocities. RESULTS LV and RV longitudinal strains were reduced in cardiac amyloidosis (CA) patients compared to controls. By multivariate analysis, LV basal LS (p = 0.002), LV peak basal rotation (p = 0.003), and RV basal FW LS (p = 0.014) were independently associated with CA in the overall population. A significant improvement in global χ2 value was noted with RV 3D-strain parameters over only LV-3DSTE + conventional indices for detection of CA (p < 0.001). Comparison of ROC curves showed that the AUC using combined LV basal LS, LV basal rotation and RV basal FW LS had a higher discriminative value than the other echocardiographic parameters used for detecting CA (AUC 0.93, 95%CI 0.81-0.97). CONCLUSIONS Three-dimensional speckle tracking echocardiography reveals regional and global biventricular dysfunction in CA. Assessment of RV ventricular dysfunction has an additive value in differentiating CA from other causes of myocardial wall thickening.

Dataset on the use of 3D speckle tracking echocardiography in light-chain amyloidosis

The dataset presented in this article is related to the research article entitled “Biventricular assessment of light-chain amyloidosis using 3D speckle tracking echocardiography: Differentiation from other forms of myocardial hypertrophy” (Vitarelli et al., 2018) [1], which examined the potential utility of left ventricular (LV) and right ventricular (RV) deformation and rotational parameters derived from three-dimensional speckle-tracking echocardiography (3DSTE) to diagnose cardiac amyloidosis(CA) and differentiate this disease from other forms of myocardial hypertrophy. The combined assessment of LV basal longitudinal strain, LV basal rotation and RV basal longitudinal strain had a high discriminative power for detecting CA. The data of this study provides more understanding on the value of LV 3DSTE deformation parameters as well as RV parameters in this particular cardiomyopathy.

Acute Aortic Dissection Mimicking STEMI in the Catheterization Laboratory: Early Recognition Is Mandatory

Coronary malperfusion due to type A aortic dissection is a life-threatening condition where timely recognition and treatment are mandatory. A 77-year-old woman underwent an acute evolving type A aortic dissection mimicking acute myocardial infarction. Two pathophysiologic mechanisms are discussed: either thrombosis migrating from a previously treated giant aneurism of proximal left anterior descending or a local arterial complication due to left main stenting. Recognition of these occurrences in the catheterization laboratory is important to look immediately for surgery.

Early metabolic response to acute myocardial ischaemia in patients undergoing elective coronary angioplasty

Objective Balloon-induced transient coronary ischaemia represents a model of myocardial ischaemia and reperfusion. We are interested in the very early systemic metabolic response to this event. Methods Blood samples of patients with stable angina (SA) were collected before and after coronary angioplasty. Serum metabolic profiles were obtained using nuclear magnetic resonance spectroscopy. Univariate and multivariate analyses were used to investigate changes in metabolite concentrations. Results Thirty-four consecutive patients with SA, undergoing elective coronary angioplasty at Policlinico Umberto I of Rome, were included in this study. Changes in metabolites concentration induced by balloon occlusion in venous and arterial sera were detected. In both serum types, a significant increase in ketone bodies, 2-hydroxybutyrate, glutamine and O-acetylcarnitine concentration is observed, while alanine, lactate, phenylalanine and tyrosine decreased after intervention. Most significant metabolic changes were detected in arterial serum. Conclusions Our study points out two main global metabolic changes in peripheral blood after balloon-induced coronary ischaemia: ketone bodies increase and lactate decrease. Both could be related to compensation mechanisms finalised to fulfil heart’s needs after short period of myocardial ischaemia and probably after reperfusion.

Glutathione sodium salt as a novel adjunctive treatment for acute myocardial infarction

Timely recanalization of infarct related artery along with effective myocardial cell reperfusion represents a major challenge in the management of STEMI. The reperfusion of coronary arteries can induce further cardiomyocyte death by generating oxidative stress, which itself can mediate myocardial damage through a number of different mechanisms. Based on experimental and clinical studies, interventions to treat reperfusion injury by antioxidants were considered to be an appropriate therapeutic option. We emphasize the hypothesis that glutathione sodium salt, a physiologic antioxidant, may be of value when administered to STEMI patients both at an early stage of myocardial reperfusion by primary angioplasty and for up to three days after the procedure, in addition to standard treatment.

A Case of Very Late Bare-Metal Coronary Stent Thrombosis Two Weeks after Aspirin Discontinuation, Histopathologic Thrombus Findings and Clinical Considerations

There have been consistent evidences that atherosclerotic changes occur inside bare metal stents (BMS) during an extended period after implantation. This report describes the histopathologic features of aspirated material harvested from a patient with definite very late stent thrombosis of a BMS implanted 18 years prior. The patient presented with a recurrent anterior acute myocardial infarction 14 day after aspirin discontinuation. We suggest that vulnerable neointimal tissue inside the stent struts of BMS may be one potential trigger of thrombosis when the protection of aspirin treatment is ceased.

Papillary fibroelastoma of the pulmonary valve-a systematic review: advantages of live/real time three-dimensional transthoracic and transesophageal echocardiography.

We read with interest, in the last issue, the manuscript entitled “Papillary Fibroelastoma of the Pulmonary Valve–A Systematic Review” by Hakim et al. This is an excellent review of echocardiography and other noninvasive modalities in the assessment of pulmonary papillary fibroelastoma. However, they do not allude to the incremental value of three-dimensional (3D) echocardiography over two-dimensional echocardiography in the assessment of these tumors. Several publications in the literature demonstrate this aspect. Evaluation of these tumors by 2D transthoracic echocardiography (TTE) is difficult from the parasternal approach as in the short-axis view, only 2 cusps of the pulmonary valve can generally be simultaneously assessed. On the other hand, all 3 leaflets can be visualized by 3DTTE and 3D transesophageal echocardiography (TEE) resulting in more comprehensive assessment of these tumors as well as the right ventricular outflow tract and pulmonary artery. Using both 3DTTE and 3DTEE, morphologic patterns of intracardiac masses as well as their mobility, deformation, shape, and orientation can be displayed in an anatomically real time manner. This provides an accurate delineation of the spatial relation of the tumor with other neighboring cardiac structures. A better definition and a volumetric acquisition can offer the true dimensions of the mass that is not limited to the finite orthogonal planes offered by 2DTEE. Volumetric acquisition can be manipulated offline by the echocardiographer with a high degree of accuracy which may have important implications in the patient prognosis, given the relation between the size of tumors and the potential for embolic events. According to Nanda et al., 3D echocardiographic evaluation should be considered as part of an ultrasound exam when an intracardiac mass is the diagnosis and when that mass needs to be followed over time. Besides, the precise site of origin and the characteristic finger-like excrescences are very representative of a pulmonary valve fibroelastoma and can be detected by echocardiography with higher temporal resolution and with other advantages such as low cost, lack of radiation exposure, and no need for a contrast dye over magnetic resonance imaging and computed tomography. 3DTTE with color Doppler echocardiography might be useful in the evaluation of tumor vascularization as well as flow acceleration around the mass due to flow obstruction. Finally, all these advantages help optimize communication between the cardiologist and the surgeon potentially resulting in guidance during surgery and better patient management.
