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.

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

Abstract 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.

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.

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.

Comparison on CMR characteristics and clinical prognosis between hypertrophic cardiomyopathy patients with and without left ventricular apical aneurysms / 中华心血管病杂志

Objective@#To compare the imaging characteristics and long-term prognosis in hypertrophic cardiomyopathy(HCM) patients with or without left ventricular apical aneurysm(LVAA).@*Methods@#Retrospectively analyzed the clinical data from 18 patients diagnosed as HCM complicating with LVAA(HCM-LVAA group), hospitalized and underwent cardiac magentic resonance (CMR) examination in Fuwai Hospital between December 2012 and December 2016. Eighteen age and gender matched patients with HCM diagnosed by CMR served as control(HCM group). Outpatient and in-hospital clinical data as well as follow up results were compared. The major adverse cardiovascular events were defined as malignant arrhythmia events (including sudden cardiac death, ventricular flutter/ventricular fibrillation) and heart failure events (including heart transplantation, progressive heart failure).@*Results@#Compared with HCM group, patients in HCM-LVAA group had a more positive family history of HCM(P=0.04), higher incidence of ST-T segment changes and abnormal Q wave in electrocardiograms (both P<0.01), the CMR derived left ventricular end-diastolic transverse diameter and end-diastolic volume index were also significantly higher (both P<0.05), and delayed enhancement was more significant ((25.26±10.60)% vs. (15.78±7.33)%, t=3.12, P=0.004) in HCM-LVAA group. Moreover, the left ventricular ejection fraction ((54.4±10.6)% vs. (67.5±7.6)%, t=-4.28, P<0.000 1) and the thickness of the apical wall ((3.11±1.05) mm vs. (5.46±1.94) mm, t=-4.49, P<0.000 1) were significantly lower in HCM-LVAA group than in HCM group. The mean follow-up duration was (3.46±1.64) years, 4 patients in HCM-LVAA group (22.2%) developed 4 cardiovascular events, including 1 sudden cardiac death, 3 progressive heart failures. One patient in HCM group developed progressive heart failure.@*Conclusion@#The prognosis of the HCM complicating with LVAA patients is worse than that of HCM patients without LVAA, and the amount of late gadolinium enhancement is higher than that of HCM patients without LVAA.

Clinical and cardiac magnetic resonance features of apical hypertrophic cardiomyopathy patients complicating with left ventricular apical aneurysm / 中华心血管病杂志

Objective@#To evaluate the clinical and cardiac magnetic resonance (CMR) features of apical hypertrophic cardiomyopathy (ApHCM) patients complicating with left ventricular apical aneurysm (LVAA).@*Methods@#CMR confirmed 25 ApHCM patients complicating with LVAA from January 2010 to December 2017 in Fuwai hospital were included in this study, and the baseline clinical data and CMR characteristics were retrospectively analyzed. There were 14 pure ApHCM (hypertrophy limited at the apical segments) complicating with LVAA patients and 11 mixed ApHCM (predominantly apical hypertrophy along with thickening of contiguous non-apical left ventricular region) with LVAA patients.@*Results@#In this patient cohort,age of 84% (21/25) patients ranged between 20-70 years old, and 68% (17/25) were male. There were 68% (17/25) patients with complaint of chest distress symptom, 56% (14/25) with complaint of chest pain, 32% (8/25) with complaint of palpitation,16% (4/25) with complaint of dyspnea, and 12% (3/25) presented as syncope. ST-T segment changes of electrocardiogram were observed in all patients, and giant negative T waves were detected in 80% patients (20/25). The rate of missed diagnosis by echocardiography for detecting ApHCM and LVAA was 16% (4/25) and 68% (17/25), respectively. CMR showed discrete thin-walled dyskinetic or akinetic segment of the most distal portion of the left ventricular chamber in ApHCM patients with LVAA. Transmural late gadolinium enhancement of the aneurysmal rim was detected in 76% (19/25) patients, and the maximum transverse dimension of aneurysm was bigger in patients with transmural late gadolinium enhancement than in patients without transmural late gadolinium enhancement ((22.0±10.8)mm vs. (11.7±4.0) mm, P=0.033).@*Conclusion@#ApHCM with LVAA patients have distinct cardiac clinical features, and CMR is the most useful tool for the accurate and objective evaluation of this disease.

Application of circular patch plasty (dor procedure) or linear repair techniques in the treatment of left ventricular aneurysms

Abstract Objective: The aim of this study was to evaluate early clinical outcomes and echocardiographic measurements of the left ventricle in patients who underwent left ventricular aneurysm repair using two different techniques associated to myocardial revascularization. Methods: Eighty-nine patients (74 males, 15 females; mean age 58±8.4 years; range: 41 to 80 years) underwent post-infarction left ventricular aneurysm repair and myocardial revascularization performed between 1996 and 2016. Ventricular reconstruction was performed using endoventricular circular patch plasty (Dor procedure) (n=48; group A) or linear repair technique (n=41; group B). Results: Multi-vessel disease in 55 (61.7%) and isolated left anterior descending (LAD) disease in 34 (38.2%) patients were identified. Five (5.6%) patients underwent aneurysmectomy alone, while the remaining 84 (94.3%) patients had aneurysmectomy with bypass. The mean number of grafts per patient was 2.1±1.2 with the Dor procedure and 2.9±1.3 with the linear repair technique. In-hospital mortality occurred in 4.1% and 7.3% in group A and group B, respectively (P>0.05). Conclusion: The results of our study demonstrate that post-infarction left ventricular aneurysm repair can be performed with both techniques with acceptable surgical risk and with satisfactory hemodynamic improvement.

Large inferolateral left ventricular aneurysm

The majority of cardiac left ventricular aneurysms involve the anterior and/or apical wall. We present a case of a 50-year-old man with heart failure caused by a large inferolateral left ventricular aneurysm and associated mitral regurgitation, managed by aneurysmectomy, mitral valvuloplasty, and surgical revascularization.

A rare cause of left ventricular assist device (lvad) obstruction: left atrial dissection

MRI late gadolinium enhancement of left ventricular apical aneurysms in hypertrophic cardiomyopathy / 中华放射学杂志

Objectives To discuss the characteristics of late gadolinium enhancement (LGE) magnetic resonance (MR) imaging in patients with hypertrophic cardiomyopathy (HCM) and left ventricular apical aneurysm (LVAA) and its related prognostic value. Methods Thirty HCM patients with LVAA were collected from August 2004 to August 2013. All cases with coronary artery diseases were ruled out, and all patients underwent LGE derived by cardiac MR (CMR). Five cases of LVAA were pathological confirmed. Atrial and ventricular diameters, apical aneurysm diameters and left ventricular ejection fraction were measured, and apical aneurysm LGE was evaluated. All patients were then followed up. Comparisons in continuous parameters between patients with or without LGE were performed by independent t test. A Cox proportional hazard model was used to estimate the hazard rate for adverse cardiovascular events. Results LGE was identified in 21 LVAAs and non-LGE in 9 LVAAs. Between two groups, there was no significant difference in the size of LVAA [(16.4 ± 11.5) mm vs. (20.3 ± 9.8) mm, P=0.63]. In particular, the complete transition from non-LGE to LGE LVAA was recorded during follow-up in one patient. Pathological findings confirmed that LGE indicated fibrous tissue in LVAA, and LVAA without LGE indicated viable myocardium. The follow-up suggested that the patterns and the size of LVAA were associated with the adverse events in these patients (LGE of LVAA, HR=7.94, P=0.064; the size of LVAA, HR=1.08, P=0.009). Conclusions LGE-MR had important clinical significance in HCM patients with LVAA. LGE in LVAA corresponded with the fibrous tissue and was associated with the prognosis.

Aneurismas, pseudoaneurismas y divertículos cardiacos / Cardiac Aneurysms, Pseudoaneurysms and Diverticula

Los aneurismas, pseudoaneurismas y divertículos cardiacos son dilataciones o evaginaciones de estructuras de la pared cardiaca: ventrículos, aurículas, septo interauricular, arterias coronarias, entre otros, de distintas causas y de morfología variable. Los avances en las diferentes modalidades diagnósticas han permitido una mayor precisión en la evaluación morfológica y funcional del corazón. Los aneurismas, pseudoaneurismas y divertículos cardiacos son manifestaciones frecuentes de diferentes condiciones, que pueden ser evaluados mediante técnicas como la resonancia magnética (RM) y la tomografía computarizada (TC) que se usan, cada vez con mayor frecuencia, para evaluar la configuración cardiaca. La resonancia magnética cardiovascular (RMC) es la técnica de elección para una mejor valoración anatómica cardiaca. El propósito de este artículo es ilustrar mediante casos clínicos el valor de estas modalidades diagnósticas no invasivas en la evaluación de los aneurismas, pseudoaneurismas y divertículos cardiacos.

Cardiac aneurysms, pseudoaneurysms, and diverticula are dilations or outpouchings of different cardiac structures: ventricles, atria, atrial septum, coronary arteries, among others, due to different causes and of variable morphology. Advances in different diagnostic modalities have allowed greater accuracy in the morphological and functional assessment of the heart. Cardiac aneurysms, pseudoaneurysms, and diverticula are common manifestations of different conditions that can be assessed by magnetic resonance imaging and computed tomography, which are increasingly used to evaluate cardiac configuration. Cardiovascular magnetic resonance (CMR) is the technique of choice for a better cardiac anatomic evaluation. This paper aims to illustrate, through clinical cases based on our experience in CediIMed, the value of these non-invasive diagnostic modalities in the evaluation of cardiac aneurysms, pseudoaneurysms, and diverticula.

Sudden Cardiac Death due to Subaortic Left Ventricular Aneurysm / 대한법의학회지

Subaortic left ventricular aneurysm is a rare, mostly congenital condition, and occurs as a result of a defect in the alveolar fibrosa between the mitral and aortic annuli. Clinically, most subaortic left ventricular aneurysms are asymptomatic, but some of them cause arrhythmia, chest pain, and even sudden cardiac death. We report an autopsy case of sudden cardiac death due to subaortic left ventricular aneurysm in a 38-year-old male sailor.

The diagnosis and treatment of acute myocardial infarction complicated with left ventricular wall rupture:a report of three cases / 天津医药

Objective To investigate the diagnosis and treatment in patients with acute myocardial infarction (AMI) and complicated left ventricular wall rupture (LVWR). Methods A retrospective analysis was made on the clinical features, diagnosis and successful treatment in three AMI patients with LVWR from December 2015 to April 2016. Results Three cases were included in this study. Case 1, the mesh like cardiac rupture after AMI was diagnosed by ultrasonic Doppler. Emergency revascularization was performed due to the combined cardiac shock, and the infarct related artery was opened. The vasoactive drugs were used after revascularization to reduce ventricular pressure load and volume load in the haemodynamic monitoring, and anticoagulation, antiplatelet agents were less used or discontinued to promote local thrombus healing of ventricular rupture. Case 2 was a recurrent myocardial infarction patient. LVWR was diagnosed by ultrasonic Doppler one day after emergency operation. The ruptured ventricular wall was encapsulated by thrombus. The drug therapy was effective in hemodynamic monitoring. LVWR was further confirmed by cardiac CT after clinical stabilization. Case 3 was diagnosed LVWR by ultrasonic Doppler four days after AMI. Because the ruptured ventricular wall was limited by incompletely organized thrombus, and the haemodynamic condition was stable, selective surgical repair of rupture after coronary angiography was performed. Conclusion The effective drug therapy combined with percutaneous coronary intervention and surgical repair can reduce the risk of death in patients with LVWR after AMI.

Clinical Features in Patients With Hypertrophic Cardiomyopathy Combining Left Ventricular Apical Aneurysm / 中国循环杂志

Objective: To analyze the clinical features in patients with hypertrophic cardiomyopathy (HCM) combining left ventricular apical aneurysm (LVAA) . Methods: A total of 1194 HCM patients treated in our hospital from 2007-01 to 2013-01 were studied. There were 23 (1.93%) patients combining with LVAA including 19 male and 4 female; coronary artery disease (CAD) was excluded and the patients received echocardiography and coronary angiography (CAG) examinations. Results: There were 21/23 LVAA patients having left mid-ventricular obstruction and 7 of them combining simultaneous left ventricular outflow obstruction.The average pressure gradient in those 21 patients was (56.8 ± 12.9) mmHg and the rest 2 patients suffered from apical hypertrophic cardiomyopathy.The mean maximum thickness of left ventricular wall was (21.8 ± 6.3) mm and the dimension of left ventricle was (39.4 ± 5.2) mm. Electrocardiography showed that 3 patients had paroxysmal ventricular tachycardia;CAG indicated that 6 patients combined with coronary artery muscular bridge at left anterior descending (LAD) artery. The patients were followed-up for (2.7 ± 1.3) years and adverse cardiovascular events occurred in 5 patients during that period. Conclusion: HCM combining LVAA was most frequently happened in patients with left mid-ventricular hypertrophic cardiomyopathy, some of them combining simultaneous left ventricular outflow obstruction and had the higher occurrence rate of adverse cardiovascular events. Early and accurate diagnosis is very important for guiding clinical treatment.

Surgical treatment of a giant left ventricular aneurysm- A case report / Tratamento cirúrgico do aneurisma gigante de ventrículo esquerdo - Relato de caso

An aneurysm of the left ventricle is a complication of acute myocardial infarction. We report a case of a giant aneurysm of the left ventricle after myocardial infarction in a 59 year-old male patient. The surgery to correct the aneurysm was performed with the use of cardiopulmonary bypass under normothermia. A bovine pericardial patch was used for the geometric reconstruction of the ventricular wall affected by the aneurysm. After the procedure, echocardiography and magnetic resonance imaging revealed improvement in left ventricular ejection fraction and volume reduction.
