ABSTRACT
This 10-minute video aims at improving skills for the structural assessment of the interatrial septum using 2-dimensional transthoracic echocardiography (TTE) to increase the ability to diagnose-or rule out-the different types of interatrial communications. Of the five types of lesions, this video focuses on ostium secundum atrial septal defect. This is the first video in our MicroLearning Video Series, designed to help a target audience of sonographers, general cardiologists, general practitioners who want to gain knowledge on fundamental cardiology, and technicians.

The antemortem diagnosis of secondary cardiac involvement by lymphoma remains suboptimal. Prognosis is worse with delayed diagnosis as the tumor burden increases with the multicompartment participation. Chemotherapy may improve survival, but there is a risk of mortality due to treatment-related complications, such as myocardial rupture and fatal arrhythmias. Modified chemotherapy regimens may prevent such complications, but the data are limited. We report the case of a 72-year-old woman diagnosed with diffuse large B-cell lymphoma with cardiac involvement, where early diagnosis prevented cardiac complications from the disease and its treatment as well. The aim of this case report is to highlight the fact that cardiac involvement in lymphoma is frequent and can be easily missed, leading to complications. Treatment requires an individualized approach.

ABSTRACT: Lipomatous hypertrophy of the interatrial septum (LHIS) is a rare but benign cardiac tumor that can be found on cardiac imaging such as echocardiogram, or during surgery or an autopsy. Cardiac MRI is the best imaging modality to determine the borders of the tumor and its extension into the intraventricular septum and ventricular free wall. Patients require close monitoring because LHIS may cause right or left outflow tract obstruction or superior vena cava obstruction, requiring cardiac surgical intervention. This article describes a patient with LHIS who underwent cardiac surgery because of her increasing symptomatology.

BACKGROUND: The purpose of this study was to describe the correlates and outcomes in adults with unrepaired partial anomalous pulmonary venous return and intact atrial septum (PAPVR-IAS). METHODS AND RESULTS: We identified adults with PAPVR-IAS who received care at the Mayo Clinic, while those with unrepaired PAPVR-IAS comprised the reference group. Clinical indices (New York Heart Association class, peak oxygen consumption, and NT-proBNP [N-terminal pro-B-type natriuretic peptide]) and echo-derived right heart indices (right atrial [RA] volume, RA reservoir strain, right ventricular [RV] free wall strain, RV end-diastolic area, and RV systolic pressure) were assessed at baseline and 3-year and 5-year follow-up. There were 80 patients and 38 patients with unrepaired versus repaired PAPVR-IAS, respectively. The clinical predictors of surgical repair were the number of anomalous veins, RA volume, and RV end-diastolic area. The PAPVR-IAS risk score, derived from these clinical predictors, was associated with surgical repair (adjusted odds ratio, 1.37 [95% CI, 1.24-1.65] per unit increase in risk score; area under the curve, 0.742). Among patients with unrepaired PAPVR-IAS with 3-year (n=73) and 5-year follow-up (n=36), there was no temporal change in clinical indices (New York Heart Association class, predicted peak oxygen consumption, and NT-proBNP) and right heart indices (RA volume index, RA reservoir strain, RV end-diastolic area index, RV free wall strain, and RV systolic pressure). CONCLUSIONS: The PAPVR-IAS risk score can be used to assess the odds of requiring surgical repair. Furthermore, there was no temporal deterioration in clinical and right heart indices during follow-up in adults with unrepaired PAPVR-IAS.

BACKGROUND: Hybrid stage I palliation (HS1P) is an alternative approach for initial palliation in hypoplastic left heart syndrome (HLHS) patients. Unlike surgical stage I palliation where atrial septectomy is routinely performed, atrial septal intervention (ASI) during HS1P is variable. In this study, we described our experience with ASI in single ventricle (SV) patients who underwent HS1P and identified factors associated with need for ASI after HS1P. METHODS: Data were retrospectively collected for all HLHS patients who underwent HS1P at our center over the past 12 years. We evaluated ASIs performed during the HS1P (intra-HS1P ASI) and ASIs performed during the period from HS1P to the subsequent surgical stage, either interval Norwood stage I or comprehensive stage II (post-HS1P ASI). Patient factors and procedural data were compared to identify factors associated with undergoing post-HS1P ASI and the impact of ASI on patient outcomes was evaluated. RESULTS: Of 50 SV patients included, 23 (46%) underwent intra-HS1P ASI and 26 (52%) underwent post-HS1P ASI. Need for post-HS1P ASI was lower among patients who had an intra-HS1P ASI as compared to those who did not (30% vs. 70%; p = 0.005). There were no significant differences in short or Midterm outcomes between patients who underwent intra-HS1P ASI or post-HS1P ASI and their counterparts. CONCLUSIONS: ASI is common both during and after HS1P but is generally well tolerated and type of ASI does not significantly impact overall patient outcomes. Our findings suggest that the current approach of individualizing management of ASI in the HS1P population is effective and safe.

A man in his 60s with paroxysmal atrial fibrillation was scheduled for a catheter ablation but was admitted to our department after contrast-enhanced CT showed a large homogeneous right atrial mass (52×52 mm) as well as a dilated right coronary artery (RCA). Coronary artery angiography showed a large fistula from the RCA to the mass in the right atrium. A giant coronary artery aneurysm was suspected and a surgical resection was performed. The mass was attached to the atrial septal wall and was palpated in the right atrium with a feeding artery from the RCA. The final diagnosis was an extremely rare case of giant coronary artery aneurysm originating from the RCA. The surgery was successful, and the patient was discharged 30 days later.

A 70-year-old man with recurrent atrial fibrillation (AF) underwent transcatheter radiofrequency ablation after an earlier unsuccessful attempt. Although typical AF triggers were ablated, the patient's condition persisted, leading to the identification of the interatrial septum (IAS) as the probable source of the tachycardia trigger. Given the depth and thickness of the IAS, traditional radiofrequency ablation proved ineffective. However, using the alternative method of bipolar radiofrequency catheter ablation (B-RFCA), the atrial tachycardia was successfully terminated. B-RFCA demonstrates potential for effectively terminating tachycardias originating from deep intramural locations, suggesting its potential as a pivotal technique for complex cases with septal atrial tachycardia.

BACKGROUND: Cardiac hemangiomas are very uncommon benign primary tumors. They are usually located preferentially in the right atrium and their location in the interatrial septum is extremely rare. CASE PRESENTATION: We report the case of a 41-year-old patient who was admitted due to a stroke. The transthoracic echocardiogram revealed a large mass in the right atrium adhered to the interatrial septum. Suspecting an atrial myxoma, surgical intervention was performed confirming that the mass extended within the thickness of the interatrial septum, protruding into the right atrial cavity. The histologic report confirmed a hemangioma. CONCLUSIONS: Cardiac hemangiomas are rare primary tumors and are usually misdiagnosed as other cardiac tumors. Histopathological examination is essential for a definitive diagnosis.

BACKGROUND: The correlation between atrial septum anatomy and the risk of ischemic neurological events remains underexplored. AIMS: This study aimed to examine both the functional and anatomical attributes of the atrial septum and identify predictors of stroke and/or transient ischemic attack (TIA) in patients diagnosed with patent foramen ovale (PFO). METHODS: A total of 155 patients diagnosed with PFO, with a cardiological cause of neurological events, were enrolled. Transesophageal echocardiography was utilized to assess the anatomy of the PFO canal, size of the right-to-left shunt, thickness of the primary and secondary atrial septum, presence of atrial septum aneurysm, and anatomical structures of the right atrium. RESULTS: Regression analysis showed that factors such as female sex, hypercholesterolemia, PFO canal width, and a large right-to-left shunt were significantly associated with stroke and/or TIA. Receiver operating characteristic analysis indicated that the width of the PFO canal holds a relatively weak, although significant predictive, value for ischemic neurological episodes (area under the curve = 0.7; P = 0.002). A PFO canal width of 4 mm was associated with 70% sensitivity and 55% specificity for predicting stroke and/or TIA. CONCLUSIONS: The atrial septum's anatomy, especially the dimensions of the PFO canal and the magnitude of the right-to-left shunt, combined with specific demographic and clinical factors, are linked to ischemic neurological incidents in PFO patients.

INTRODUCTION: Percutaneous left atrial appendage occlusion (LAAO) is traditionally performed under general anesthesia with trans-esophageal echocardiography guidance. Intracardiac echo (ICE)-guided LAAO closure is increasing in clinical use. The ICE catheter is crossed into LA via interatrial septum (IAS) after the septum is dilated with LAAO delivery sheath. This step can be time-consuming and requires significant ICE catheter manipulation, which increases the risk of cardiac perforation. Pre-emptive septal balloon dilation can potentially help with ICE advancement in the LA. We sought to evaluate the effect of pre-dilation of the IAS with an 8 mm balloon on the ease of crossing the ICE catheter, fluoroscopy time for crossing, and overall procedure time. METHODS: The Piedmont LAAO registry was used to identify consecutive patients who underwent LAAO. The initial 25 patients in whom balloon dilation of the IAS was performed served as the experimental cohort, and the 25 consecutive patients before that in whom balloon dilation was not performed served as controls. In the experimental group, after a trans-septal puncture, the sheath was retracted to the right atrium with a guidewire still in the LA. An 8 × 40 mm Evercoss™ over the wire balloon was inflated across the IAS. The ICE catheter was then crossed into the LA using the fluoroscopic landmark of the guide wire and the ICE imaging. The sheath was then advanced along the ICE catheter via the transseptal puncture (TSP) and the procedure continued. Follow-up compputed tomography imaging was obtained at 4-8 weeks. RESULTS: Each group consisted of 25 patients. There were no significant differences in baseline characteristics. All procedures were performed successfully under conscious sedation and ICE guidance. There was a significant reduction in the overall procedure time, fluoroscopy time, and time for transseptal puncture to ICE in LA. There was no difference in the size of the acute residual interatrial shunt, as measured via ICE, or the size and presence of iatrogenic ASD at follow-up. CONCLUSION: Balloon dilation of TSP is safe and is associated with increased efficiency in ICE-guided LAAO procedures.

PURPOSE: This study was designed to investigate the application value of the atrial septum excursion index (ASEI) in fetuses with isolated restrictive foramen ovale (RFO) or redundant foramen ovale flap (RFOF) and the outcomes of these fetuses. METHODS: This was a retrospective study. Healthy pregnant women who were examined by antenatal fetal echocardiography from January 1, 2019 to December 31, 2021, at Sir Run Run Shaw Hospital were enrolled. One hundred seventy-seven (177) fetuses were categorized into three groups by diagnosis: (1) RFOF (n = 33), (2) RFO (n = 21), and (3) normal (n = 123). Fetal echocardiographic features and postnatal outcomes were collected. RESULTS: The median ASEIs were 0.50 (range, 0.41-0.65) in the control group, 0.76 (range, 0.67-0.88) in the RFOF group and 0.31 (range, 0.14-0.35) in the RFO group, and the differences were significant (p < 0.001). The ratios of right atrium/left atrium, right ventricle/left ventricle, and pulmonary artery diameter to aorta diameter (PA/AO) and the pulmonary annulus Z-scores were greater in fetuses with RFOF and RFO than in the controls (p < 0.05). Twenty-seven of 33 fetuses (87.9%) with RFOF and 19 of 21 fetuses (90.5%) with RFO had good outcomes after birth. CONCLUSION: The ASEI may be a new tool for quantitatively assessing the mobility of foramen ovale flaps in fetuses with isolated RFOF or RFO.

BACKGROUND: Patent foramen ovale (PFO) is causally associated with stroke in some patients younger than 60 years, especially when it is large or associated with an atrial septal aneurysm (ASA). After 60 years of age, this association is less well understood. We assessed the relationships between detailed atrial septal anatomy and the cryptogenic nature of stroke in this population. METHODS AND RESULTS: We reviewed all patients aged 60 to 80 years admitted to our stroke center for ischemic stroke who underwent contrast echocardiography between 2016 and 2021. The atherosclerosis, small-vessel disease, cardiac pathology, other causes, and dissection (ASCOD) classification was used to reevaluate the etiological workup. Associations between cryptogenic stroke and (1) PFO presence or (2) categories of PFO anatomy (nonlarge PFO without ASA, nonlarge PFO with ASA, large PFO without ASA, and large PFO with ASA) were assessed using logistic regression. Among 533 patients (median National Institutes of Health Stroke Scale score=1), PFO was present in 152 (prevalence, 28.5% [95% CI, 24.9-32.5]). Compared with noncryptogenic stroke, cryptogenic stroke (n=218) was associated with PFO presence (44.5% versus 17.5%; P<0.0001). Among patients with a PFO, septal anatomy categories were associated with cryptogenic stroke (P=0.02), with a strong association for patients with both large PFO and ASA (38.1% versus 14.5%, P=0.002). CONCLUSIONS: PFO presence remains strongly associated with cryptogenic stroke between 60 and 80 years of age. Large PFO, ASA, and their association were strongly associated with cryptogenic stroke in this age group. Our results support performing contrast echocardiography even after 60 years of age, although the optimal secondary prevention therapy in this population remains to be determined in randomized trials.

BACKGROUND: Cardiac papillary fibroelastoma is a rare benign tumor, which is often mistaken for a vegetation. Predominantly asymptomatic, it can cause life-threatening complications. Although rare, mobile papillary fibroelastoma movement between affected valves may hamper valve closure and damage the valve, leading to valvular regurgitation. Endothelial damage increases the risk of developing infective endocarditis. We report a rare case of a highly mobile papillary fibroelastoma originating from the atrial septum touching the mitral valve, leading to mitral regurgitation and, eventually, infective endocarditis. CASE PRESENTATION: A 26-year-old woman with suspected infective endocarditis was referred to us from a previous hospital after having experienced intermittent fever for a month. Before the fever, she had been experiencing exertional dyspnea. In addition, she had undergone a cesarean section two weeks before this admission. A transthoracic echocardiogram showed a mobile mass originating from the atrial septum touching the mitral valve with severe mitral regurgitation. Computed tomography revealed an occluded right profunda femoris artery with an embolus. Infective endocarditis associated with a mobile vegetation with high embolic risk was diagnosed, and urgent surgery was performed. Following the surgery, examinations revealed papillary fibroelastoma originating from the atrial septum and infective endocarditis of the mitral valve. The histopathological examination confirmed that a mass initially thought to be a mobile vegetation was a papillary fibroelastoma. The postoperative course was uneventful except for pericarditis. There has been no recurrence of infective endocarditis or papillary fibroelastoma. CONCLUSIONS: The highly mobile papillary fibroelastoma was thought to have caused both chronic mitral regurgitation and infective endocarditis. Mobile papillary fibroelastomas can cause endothelial damage to nearby valves and predispose patients to infective endocarditis.
