Case Report: Heart aneurysm of unknown origin in a two-year-old child diagnosed in the course of Multisystem Inflammatory Syndrome in Children.

We present a case of a 22-month-old boy with a hypokinetic and thin-walled aneurysm of the left ventricle apex. The lesion was diagnosed during routine echocardiography examination in the course of MIS-C, and its occurrence due to MIS-C is plausible. Cardiac magnetic resonance imaging revealed an akinetic aneurysm of the LV apex with a full-wall ischemic scar. Aortography confirmed a normal course of coronary arteries, with adequate perfusion of essential branches and no evidence of stenosis or aneurysms. The boy underwent consultation with the heart team and was deemed eligible for surgery. The aneurysm was excised up to the margin of healthy tissues, and both the surgery and the periprocedural period were uneventful. Determining the origin of the aneurysm is challenging. The most probable etiology appears to be a congenital lesion. Another consideration is an ischemic lesion that may have resulted from impaired coronary circulation during the complicated course of MIS-C. It is possible that this disturbance resolved spontaneously before aortography was performed. Additionally, a complication of pericarditis cannot be entirely ruled out.

Vascular aneurysms in Ehlers-Danlos syndrome subtypes: A systematic review.

Aneurysmal lesions are commonly seen in Ehlers-Danlos Syndrome (EDS). To better identify the regional and vessel-specific spectrum of aneurysms in different subtypes of EDS, we performed a systematic review. We searched Medline for relevant studies from 1963 to April 2022. Studies providing a report of any EDS subtype by genetic diagnosis, histologic analysis, or clinical criteria were included. A total of 448 patients from 220 studies were included. 720 vessel-specific aneurysms were reported: 386 in the abdominopelvic area, 165 in the intracranial region, 98 in the thorax, 2 in the extremities, and 6 in the venous system. In 27 out of the 65 patients with ruptured aneurysms, the ruptured aneurysm was the initial presentation. Multiple aneurysms were present in 163 out of 249 patients who had been systematically evaluated for other locations of aneurysms. The head and neck and abdominopelvic regions are two potential foci for aneurysm formation in patients with EDS. The aneurysm development in EDS is not confined to arteries; the venous system and cardiac septa may also be affected. Many patients develop multiple aneurysms, either at the time of the initial presentation or throughout their lifetime and aneurysm formation or rupture may be the first presentation of EDS.

Prenatal echocardiographic features and outcomes of congenital ventricular outpouching in ten fetuses / 中华围产医学杂志

Objective:To summarize the echocardiographic features and outcomes in fetuses with congenital ventricular outpouching (CVO).Methods:This retrospective study enrolled ten fetuses diagnosed with CVO by fetal echocardiography in the Affiliated Hospital of Qingdao University and Qingdao Women and Children's Hospital from January 2015 to April 2022. Clinical data were analyzed, including echocardiographic features, other intracardiac and extracardiac malformations, karyotypes, and pregnancy outcomes. Data were analyzed by descriptive statistics.Results:All ten cases were single, including eight ventricular diverticula and two ventricular aneurysms. Five cases had the anomaly in the left ventricular and the other five in the right. Five cases were isolated malformations, and the other five were complicated by other intra- or extracardiac malformations. A pathogenic copy number variation was detected in one case. Three pregnancies were terminated, and one was lost to follow-up. The other six fetuses were born alive and showed no obvious clinical symptoms or abnormalities in growth and development during 3-70 months of follow-up. The right ventricular diverticulum spontaneously disappeared in one case. One case with the right ventricular aneurysm was also diagnosed with noncompaction of the left ventricular myocardium by echocardiography at six months.Conclusions:Fetal CVO presents with typical echocardiographic features and can be diagnosed prenatally. Regular follow-up during pregnancy is recommended to observe the sizes of outpouchings and the occurrence of complications in fetuses with CVO after excluding other structural and chromosomal abnormalities to avoid unnecessary termination. Attention should also be paid to postnatal follow-up.

Repair of Congenital Right Atrial Aneurysm Associated With Wolff-Parkinson-White Syndrome in a 5-Year-Old Girl.

This report describes our experience with a 5-year-old girl who had an extremely rare presentation of a right atrial aneurysm and associated Wolff-Parkinson-White syndrome. Before being referred to our department, she underwent an ineffective radiofrequency ablation for repeated episodes of paroxysmal supraventricular tachycardia that were causing dizziness, palpitations, and chest discomfort. We resected the aneurysm with good results; she was doing well and was in normal sinus rhythm at the time of her 1-year follow-up visit.

Surgical Reconstruction of a Left Ventricular Aneurysm Using an Extracellular Matrix Patch.

The left ventricular aneurysm is a pathological condition defined as an akinetic or dyskinetic area of the left ventricle (LV) wall associated with reduced ejection fraction. The most common surgical technique to reconstruct a left ventricular aneurysm is endoventricular patch plasty (Dor procedure). In this case, endoventricular reconstruction of the left ventricular aneurysm using a double-layer extracellular matrix was performed.

Surgical repair of a giant congenital right atrial aneurysm concomitant with Wolff-Parkinson-White syndrome: A case report and literature review.

Atrial Septal Aneurysm and Atrial Septal Defect Association - an Uncommon But Well-Recognized Association

Abstract Atrial septal aneurysm (ASA) is an uncommon but well-recognized cardiac abnormality. This educational text reviews the case of a 54-year-old female presenting an ASA related to a small ostium secundum atrial septal defect. The considerable signs and symptoms, interestingly, have not been justified by the clinical and hemodynamic investigations. So, we opted for a better imaging investigation with cardiac catheterization and transesophageal echocardiography. The surgical process was earlier indicated and performed with aid of cardiopulmonary bypass.

Successful coil embolization of a large right coronary artery-coronary sinus fistula causing a significant left-to-right shunt: a case report.

BACKGROUND: This case reviews a challenging but successful transcatheter coil embolization of a large congenital coronary artery fistula (CAF) causing a significant left-to-right shunt. CASE SUMMARY: A 51-year-old female with no significant prior history presented with symptoms of dyspnoea and chest discomfort. Extensive evaluation revealed a large CAF between a tortuous right coronary artery (RCA) and the coronary sinus (CS) composed of three aneurysmal pseudochambers. Closure of the RCA-CS fistula was attempted through coil deployment into the fistula neck. However, due to the brisk flow through the fistula, both coils embolized into the fistula sac. An alternative location was subsequently identified on three-dimensional rendering of a computed tomography angiography scan, which revealed a sharp bend in the RCA prior to the fistula neck and distal to the posterior descending artery (PDA) takeoff. Repeat attempt at embolization was accomplished using a telescoping system to reach and occlude the targeted bend. The coil mass remained stable and angiography demonstrated reduced flow through the fistula and preserved patency of the PDA. The decreased residual flow through the fistula secondary to the initial embolization attempt likely aided the successful deployment of coils in the second and final attempt. At 1 year, the patient was doing well with resolution of her symptoms and no clinical symptoms of coronary ischaemia. DISCUSSION: We suggest that an initial unsuccessful attempt at transcatheter embolization of a CAF should not preclude subsequent attempts for closure when there exists an appropriate indication.

Comunicación interventricular post-infarto agudo de miocardio: una complicación inusual pero mortal / Ventricular septal defect after acute myocardial infarction: an unusual but life-threatening complication

Resumen Introducción: la revascularización temprana ha reducido la presencia de complicaciones mecánicas del infarto agudo de miocardio; la comunicación interventricular suele ocurrir entre el tercer y quinto día después del infarto. Se presenta el caso de un paciente poco usual y en quien los síntomas predominantes fueron principalmente gástricos. Descripción: paciente masculino de 65 años, con historia de hipertensión arterial, tabaquismo activo y consumo frecuente de alcohol, quien consultó por síntomas gastrointestinales y dolor torácico de características atípicas. En el examen físico se encontró un soplo holosistólico de predominio en los focos de la base. El electrocardiograma documentó QS en pared inferior, sin alteraciones del segmento ST-T, biomarcadores positivos y el ecocardiograma encontró disfunción sistólica, aneurisma del segmento basal y medio de la pared inferior con comunicación interventricular con flujo de izquierda a derecha. Fue llevado a coronariografía diagnóstica encontrándose enfermedad severa de dos vasos y luego fue intervenido quirúrgicamente para corrección de aneurisma ventricular, comunicación interventricular y bypass coronario. Conclusión: reconocer las manifestaciones clínicas atípicas del infarto agudo de miocardio y un examen físico bien realizado permiten identificar problemas muy serios, como las complicaciones mecánicas del infarto.

Abstract Introduction: early coronary revascularization has reduced the occurrence of mechanical complications of acute myocardial infarction; ventricular septal defect (interventricular communication) usually occurs between the third and fifth days after the event. We present an unusual case where the predominant symptoms were mainly gastrointestinal. Description: A 65-year-old male patient with a history of high blood pressure, active smoking and frequent alcohol consumption, consulted for gastrointestinal symptoms and chest pain with atypical characteristics. In the physical examination a holosystolic murmur with predominance in the foci of the base was found, the electrocardiogram documented QS in the inferior wall without alterations of the ST-T segment, positive cardiac biomarkers and the echocardiogram reported systolic dysfunction, basal and middle segment aneurysm of the lower wall, with ventricular septal defect with left to right flow. A diagnostic coronary angiography was performed founding two vessel severe disease, then the patient was surgically intervened for ventricular aneurysm correction, ventricular septal defect and coronary bypass. Conclusion: Recognizing the atypical clinical manifestations of acute myocardial infarction and a well-performed physical examination make it possible to identify serious problems such as the mechanical complications of infarction.

Aneurisma apical en paciente con miocardiopatía hipertrófica / Apical aneurysm in a patient with hypertrophic cardiomyopathy

We report a 51-year-old asymptomatic male, with type II diabetes, referred to our outpatient clinic due to ST and T alterations on the precordial leads on the electrocardiogram. The echocardiogram showed apical akinesia and left ventricular hypertrophy. There were no angiographic lesions in the coronary angiography. In the left ventriculography, a hyperdynamic left ventricle with suspected left ventricular hypertrophy and an apical aneurysm were found. The cardiac magnetic resonance confirmed those findings, without late gadolinium enhancement. According to the European Cardiology Society Risk Score, the patient had a low sudden death risk. However, this score does not consider the presence of an aneurysm as risk factor for sudden death, but it is considered in the 2017 ACC/AHA Heart Rhythm Society Guidelines, as a major risk factor. Therefore a defibrillator was implanted, and he was discharged on permanent oral anticoagulation.

A giant left ventricular pseudoaneurysm diagnosed after double-valve replacement.

A diagnostic coronary catheter injury to the subaortic region in a 41-year-old woman with rheumatic heart disease led to a pseudoaneurysm that later caused extrinsic left coronary compression. She subsequently underwent double-valve replacement, overlooking the pseudoaneurysm that enlarged to a giant size three months later following thrombolysis for mitral prosthesis thrombosis. A thrombolysis-induced large intracerebral hemorrhage posed a significant risk for reoperation, and mechanical prosthetic valves in the aortic and mitral positions allowed a catheter option only, through percutaneous transapical access. Interventional closure of the pseudoaneurysm is discussed in this unique report.

Surgical Endoepicardial Linear Ablation for Ventricular Tachycardia With Postinfarction Left Ventricular Aneurysm.

This retrospective study evaluated the feasibility of surgical endoepicardial linear ablation for ventricular tachycardia in patients with postinfarction left ventricular aneurysm. Sixty-four patients with multivessel coronary artery disease and left ventricular aneurysm but no mural thrombosis of the aneurysm or valve disease were treated at our institution from March 2012 through July 2015. All underwent off-pump coronary artery bypass grafting and left ventricular aneurysm repair by linear plication. Twenty-three patients (35.9%) had ventricular tachycardia and underwent surgical endoepicardial linear ablation on the beating heart guided by epicardial substrate mapping with the Carto 3 system. The remaining 41 patients (64.1%) composed the no-ablation group. The effectiveness of surgical linear ablation in the ablation group was evaluated. Safety and clinical outcomes were evaluated and compared between the groups. The ventricular tachycardia recurrence rate in the ablation group was 17.4% in the immediate postoperative period and 23.8% at last follow-up (39 ± 21 mo). Early (<30-d) mortality rates were 8.7% in the ablation group and 4.9% in the no-ablation group (P=0.41); the respective late mortality rates were 19.1% and 18% (P=0.70). Multivariate Cox regression analysis indicated that preoperatively poor left ventricular function was an independent risk factor for early and late death in both groups. The groups were similar in terms of the need for postoperative mechanical circulatory support, intensive care unit stay, and cumulative survival rate. We conclude that, for carefully selected candidates, surgical endoepicardial linear ablation combined with off-pump coronary artery bypass grafting and left ventricular aneurysm linear plication is a feasible treatment for ventricular tachycardia with postinfarction left ventricular aneurysm.
