RESUMO

BACKGROUND: Patients with intermediate-risk pulmonary embolism (PE) and normotensive shock may have worse outcomes. However, diagnosis of normotensive shock requires invasive hemodynamics. Our objective was to assess the predictive value of McConnell's sign in identifying normotensive shock in patients with intermediate-risk PE. METHODS: Patients with intermediate-risk PE who underwent percutaneous mechanical thrombectomy between August 2020 and April 2023 at a large academic public hospital were included in the study. Normotensive shock was defined as systolic blood pressure ≥ 90 mmHg without vasopressor support with pre-procedural invasive measures of cardiac index ≤2.2 L/min/m2 and clinical evidence of hypoperfusion (i.e. elevated lactate, oliguria). The primary outcome was the association between McConnell's sign and normotensive shock. RESULTS: Those with McConnell's sign (29/40, 72.5 %) had higher heart rate (114 vs 99 beats/min, p = 0.008), higher rates of elevated lactate (86 % vs 55 %, p = 0.038), lower cardiac index (1.9 vs 3.1 L/min/m2, p = 0.003), and higher rates of normotensive shock (76 % vs 27 %, p = 0.005). McConnell's sign had a sensitivity of 88 % and specificity of 53 % for identifying intermediate-risk PE patients with normotensive shock. Patients with McConnell's sign had an increased odds (odds ratio 8.38, confidence interval: 1.73-40.53, p = 0.008; area under the curve 0.70, 95 % confidence interval: 0.56-0.85) of normotensive shock. CONCLUSION: This is the first study to suggest that McConnell's sign may identify those in the intermediate-risk group who are at risk for normotensive shock. Larger cohorts are needed to validate our findings.

RESUMO

PURPOSE OF REVIEW: Although rare, the development of mechanical complications following an acute myocardial infarction is associated with a high morbidity and mortality. Here, we review the clinical features, diagnostic strategy, and treatment options for each of the mechanical complications, with a focus on the role of echocardiography. RECENT FINDINGS: The growth of percutaneous structural interventions worldwide has given rise to new non-surgical options for management of mechanical complications. As such, select patients may benefit from a novel use of these established treatment methods. A thorough understanding of the two-dimensional, three-dimensional, color Doppler, and spectral Doppler findings for each mechanical complication is essential in recognizing major causes of hemodynamic decompensation after an acute myocardial infarction. Thereafter, echocardiography can aid in the selection and maintenance of mechanical circulatory support and potentially facilitate the use of a percutaneous intervention.

RESUMO

The increase of intravenous drug use has led to an increase in right-sided infective endocarditis and its complications including septic pulmonary embolism. The objective of this study was to compare the outcomes of tricuspid valve (TV) operations in patients with drug-use infective endocarditis (DU-IE) complicated by septic pulmonary emboli (PE). Hospitalizations for DU-IE complicated by septic PE were identified from the National Inpatient Sample from 2002 to 2019. Outcomes of patients who underwent TV operations were compared with medical management. The primary outcome was the incidence of major adverse cardiovascular events (MACEs), defined as in-hospital mortality, myocardial infarction, stroke, cardiogenic shock, or cardiac arrest. An inverse probability of treatment weighted analysis was utilized to adjust for the differences between the cohorts. A total of 9,029 cases of DU-IE with septic PE were identified (mean age 33.6 years), of which 818 patients (9.1%) underwent TV operation. Surgery was associated with a higher rate of MACE (14.5% vs 10.8%, p <0.01), driven by a higher rate of cardiogenic shock (6.1% vs 1.2%, p <0.01) but a lower rate of mortality (2.7% vs 5.7%, p <0.01). Moreover, TV operation was associated with an increased need for permanent pacemakers, blood transfusions, and a higher risk of acute kidney injury. In the inverse probability treatment weighting analysis, TV operation was associated with an increased risk for MACE driven by a higher rate of cardiogenic shock and cardiac arrest, but a lower rate of mortality when compared with medical therapy alone. In conclusion, TV operations in patients with DU-IE complicated by septic PE are associated with an increased risk for MACE but a decreased risk of mortality. Although surgical management may be beneficial in some patients, alternative options such as percutaneous debulking should be considered given the higher risk.

RESUMO

Rhythm control strategies in patients with esophageal varices and atrial arrhythmias pose a unique challenge. The left atrium should be imaged for a thrombus prior to attempting cardioversion or ablation, but the presence of varices is a relative contraindication for transesophageal echocardiography. We present a safe, novel technique of evaluating for left atrial thrombus with simultaneous transesophageal echocardiography and esophagogastroduodenoscopy using slim probes in a patient with large, high-risk esophageal varices, and symptomatic atrial flutter with rapid ventricular rates despite medical therapy.

RESUMO

Echocardiography is the preferred initial imaging method for assessment of cardiac masses. Cardiac magnetic resonance (CMR) imaging, with its excellent tissue characterization and wide field of view, may provide additional unique information. We evaluated the predictive value of echocardiography and CMR imaging parameters to identify tumors and malignancy and to provide histopathologic diagnosis of cardiac masses. Fifty patients who underwent CMR evaluation of a cardiac mass with subsequent histopathologic diagnosis were identified. Echocardiography was available in 44 of 50 cases (88%). Echocardiographic and CMR characteristics were evaluated for predictive value in distinguishing tumor versus nontumor and malignant versus nonmalignant lesions using histopathology as the gold standard. The Wilcoxon rank-sum test was used to compare the 2 imaging methods' ability to provide the correct histopathologic diagnosis. Parameters associated with tumor included location outside the right atrium, T2 hyperintensity, and contrast enhancement. Parameters associated with malignancy included location outside the cardiac chambers, nonmobility, pericardial effusion, myocardial invasion, and contrast enhancement. CMR identified 6 masses missed on transthoracic echocardiography (4 of which were outside the heart) and provided significantly more correct histopathologic diagnoses compared to echocardiography (77% vs 43%, p <0.0001). In conclusion, CMR offers the advantage of identifying paracardiac masses and providing crucial information on histopathology of cardiac masses.

RESUMO

Aneurysms of the branches of the coronary arteries are rare. We report a case of a right coronary artery aneurysm with aneurysmal dilation and thrombosis of the sinoatrial nodal branch presenting as a right atrial mass. The patient underwent multiple imaging evaluations before coronary CT angiography diagnosed aneurysm and thrombosis of the sinoatrial nodal branch.

RESUMO

Intravenous agitated saline injection is useful in identifying right-to-left shunting at the atrial or intrapulmonary level. Anomalous systemic venous drainage to the left atrium is a rare but easily correctable cause of right-to-left shunting which, if left undiagnosed, may have serious consequences, including meningitis and pyogenic brain abscesses. This case illustrates an unusual cause of right-to-left shunting and the utility of venous microbubble injection in its diagnosis.

RESUMO

BACKGROUND: Traditional mitral annuloplasty devices include both rigid rings, which restrict annular motion, and soft rings and bands, which can locally deform. Conflicting data exist regarding their impact on annular dynamics. We studied mitral annuloplasty with a semirigid partial band and with a nearly complete rigid ring. METHODS: Intraoperative three-dimensional transesophageal echocardiograms (n = 14) and predischarge transthoracic echocardiograms were retrospectively analyzed in patients undergoing mitral valve repair for degenerative disease with either a rigid ring (n = 77) or a semirigid partial band (n = 38). Each transesophageal echocardiogram was analyzed with TomTec three-dimensional software to produce cardiac cycle frame planimetry and to measure device geometry. Actual device sizes provided reference dimensions. Blinded analysis of Doppler data from transthoracic echocardiograms was performed. RESULTS: Validation of the quantitative transesophageal echocardiogram methodology revealed a 1.3% +/- 0.3% (mean +/- standard error of the mean) underestimation of actual linear dimension. With the semirigid partial band, systolic valve orifice area and intertrigonal distance decreased from 6.14 +/- 0.37 to 5.55 +/- 0.24 cm(2) (-9.6%; p = 0.01) and from 2.69 +/- 0.08 to 2.55 +/- 0.13 cm (-5.2%; p = 0.03), respectively. Systolic anterior-posterior distance decreased from 2.1 +/- 0.10 to 1.95 +/- 0.06 cm (-7.1%; p = 0.01) compared with diastole. In contrast, rigid ring orifice area was unchanged (4.12 +/- 0.15 to 4.10 +/- 0.16 cm(2); -0.5%; p = 0.48) during the cardiac cycle. Transthoracic echocardiography revealed significantly lower mitral inflow gradients with semirigid partial band (mean gradients compared with rigid ring, 4.0 +/- 0.3 versus 5.0 +/- 0.3 mm Hg; p = 0.02; peak gradients, 8.9 +/- 0.5 versus 11.1 +/- 0.5 mm Hg; p = 0.01). CONCLUSIONS: Three-dimensional transesophageal echocardiographic measurements of annular dynamics are valid and reliable when discrete annuloplasty devices are present. In contrast to the rigid ring, the semirigid partial band permits more physiologic geometric changes and is associated with lower postoperative mitral valve gradients.

RESUMO

BACKGROUND: Patients after cardiac operation pose a challenge to the treating physician-these patients may become critically ill and are among the most difficult to image using transthoracic echocardiography. Several factors contribute to this, including difficulties in positioning the patient, inability of the patient to cooperate with instructions, surgical dressings, and hyperinflated lungs. Transesophageal echocardiography may be performed when transthoracic echocardiography is not diagnostic; however, transesophageal echocardiography is semi-invasive and does not lend itself to prolonged or repeated monitoring. METHODS: Recently, a new approach to echocardiography for use in the patient after operation has been introduced with the modification of the standard mediastinal drainage tube to allow for substernal epicardial echocardiography (SEE). The SEE tube has 2 lumens. The first allows for routine mediastinal drainage and the second has a blind end that permits the insertion of a standard transesophageal echocardiographic probe for high-resolution imaging as often as is desired over the period during which the mediastinal tube is in place. CONCLUSION: This article reviews the technique of SEE including a description of the method of performance of SEE (with representative images), a review of the published literature on this new modality, examples of clinical use, and a discussion of the advantages, indications, and limitations of SEE with an eye toward future directions for research.

RESUMO

Severe aortic plaques seen on transesophageal echocardiography (TEE) are a high-risk cause of stroke and peripheral embolization. Evidence to guide therapy is lacking. Retrospective information was obtained regarding the occurrence of embolic events (stroke, transient ischemic attacks, or peripheral emboli) in 519 patients with severe thoracic aortic plaque seen on TEE since 1988. Treatment with statins, warfarin, or antiplatelet medications was noted. Treatment was not randomized. In a matched-paired analysis, each patient taking each class of therapy was matched for age, gender, previous embolic event, hypertension, diabetes, congestive failure, and atrial fibrillation to someone not taking that medication. Multivariate analysis was also performed. An embolic event occurred in 111 patients (21%). Multivariate analysis showed that statin use was independently protective against recurrent events (p = 0.0001). Matched analysis also showed a protective effect of statins (p = 0.0004; absolute risk reduction 17%, relative risk reduction 59%, number needed to treat [n = 6]). No protective effect was found for warfarin or antiplatelet drugs. The odds ratio for embolic events was 0.3 (95% confidence interval [CI] 0.2 to 0.6) for statin therapy, 0.7 (95% CI 0.4 to 1.2) for warfarin, and 1.4 (95% CI 0.8 to 2.4) for antiplatelet agents. Thus, there is a protective effect of statin therapy, and no significant benefit of warfarin or antiplatelet drugs on the incidence of stroke and other embolic events in patients with severe thoracic aortic plaque on TEE.
