RESUMO

BACKGROUND: While the aneurysms of the membranous septum (AVS) are rare, the possibility that they lead to obstruction is even rarer. To the best of our knowledge, 11 similar cases have been reported since 1982. CASE PRESENTATION: Initially, the five-year-old boy was evaluated for dyspnoea that had been present since birth. He did not receive any medical treatment until the previous year. At the age of four, the transthoracic echocardiography showed a large aneurysm extending to the right ventricular outflow tract (RVOT) and causing RVOT stenosis. Complete surgical resection of the aneurysmal tissue was performed, and the boy was discharged home in satisfactory condition. CONCLUSIONS: As the occurrence of RVOT obstruction by a membranous ventricular septal aneurysm is very rare, we are reporting the second case in which an aneurysm of the membranous septum dynamically obstructed the RVOT in a child. We are also reviewing all the previously reported similar cases in the literature. Further studies are needed to obtain a more comprehensive understanding of aneurysms of the membranous septum (AVS).

RESUMO

BACKGROUND: Left ventricular aneurysm (LVA) is indicator of high morbidity in Chagas' disease. A cross-sectional study performed identified LVA in 18.8% of the chronic chagasic patients (CCP). OBJECTIVE: Determine the risk of death of patients with chronic chagasic cardiopathy (CCC) and LVA in 24-year interval. MATERIAL AND METHODS: In 1995 a cohort of 298 CCP was evaluated by anamnesis, physical examination, EKG and ECHO and classified in groups: G0 = 86 without cardiopathy; G1 = 156 with cardiopathy without LVA and G2 = 56 with cardiopathy and LVA. 38 patients of G0 and G1 used benznidazole. Information about the deaths was obtained in the notary, death certificates, hospital records and family members. FINDINGS: Were registered 113 deaths (37.9%): 107 (35.9%) attributed to cardiopathy and 6 (2.0%) to other causes (p < 0.05). Amongst these 107 deaths, 10 (11.6%) occurred in G0; 49 (31.4%) occurred in G1 and 48 (85.7%) occurred in G2 (p < 0.05). The risk of death was 2.7 and 7.4 times significantly higher in G2, than in G1 and G0, respectively. CONCLUSION: Chronic chagasic patients with LVA and ejection fraction < 45% have a higher risk of death than those without.

RESUMO

BACKGROUND: Mitral valve aneurysm (MVA) is a saccular outpouching of the mitral leaflet which expands on systole and collapses during diastole. The case of MVA was first described in 1729 by Morand. It is one of the rare entities with a reported incidence of only 0.2-0.29% and no such case reported in Pakistan before. CASE PRESENTATION: A 51 year old female presented with dyspnea and chest pain for 3 months. Upon investigating, trans-esophageal echocardiography (TEE) revealed thickened anterior mitral valve leaflet with rolled up margins, forming an aneurysm, with severe mitral regurgitation. Subsequently, the valve was evaluated intra-operatively for repair but eventually had to be excised and then successfully replaced with a bioprosthetic valve. CONCLUSIONS: TEE is an excellent technique to confirm the diagnosis of a mitral valve leaflet aneurysm, and depending upon the severity of the defect, valve repair can be attempted but replacement becomes the most suitable treatment modality, once repair is deemed impossible. We hereby report a rare case, where timely diagnosis, appropriate surgical intervention and regular post-operative follow up helped in achieving good prognosis of this rare entity.

RESUMO

Hypertrophic cardiomyopathy with left ventricular (LV) mid-cavity obstruction and LV apical aneurysm is associated with high morbidity and mortality rates. However, consensus is lacking on the treatment modality for LV mid-cavity obstruction and LV apical aneurysm. Here, we report a case of reduced LV mid-cavity pressure gradient and symptoms, treated using permanent pacing. The effect of permanent pacing on pressure gradient and symptoms lasted for 4 years. As pacing is relatively non-invasive compared to surgical therapy, permanent pacing is a good option, especially in the elderly patients with LV mid-cavity obstruction and apical aneurysm.

RESUMO

BACKGROUND: The causal relationship between patent foramen ovale (PFO) and migraine with aura (MA) is controversial. We aimed at exploring whether attack clinical features relate to the presence of right-to-left shunt (RLS) in MA patients. METHODS: We retrospectively examined a cohort of consecutive patients diagnosed with MA in our headache center and undergoing transcranial doppler (TCD) for RLS detection. We collected from our clinical electronic dossiers, clinical features of MA attacks (type, frequency, duration of aura phenomenon, trigger factors, onset age), family history for MA, thrombophilia genotypes, and the response to preventive treatments. RLS was stratified for severity according to the results of the TCD examination. RESULTS: We found 111 patients. Binary logistic regression analysis showed that among features of MA attacks, only onset age was associated with the presence of RLS (p < 0.0001). Patients with RLS presented the first MA attack at a younger age (p < 0.0001). The greater RLS severity, the younger was onset age (p < 0.00001) and the presence of atrial septal aneurysms (ASA) was associated with a further decrease in onset age (ρ = -539, p < 0.00001). Family history for MA was associated with the presence of RLS (chi-square p = 0.022). Response to preventive treatments was not influenced by the type of treatment (antiplatelet compared with no antiplatelet drugs), comorbidity with migraine without aura, RLS presence, or by their double interactions (Logistic regression, consistently p > 0.05). CONCLUSION: Our findings support the hypothesis that although PFO does not influence MA attack frequency, it is not merely a bystander in MA physiopathology, as RLS, its severity, and the presence of ASA possibly make a difference in the disease history.

RESUMO

Atrial septal aneurysms have two mechanisms for cardioembolic events. One is the aneurysm itself can act as a nidus for thrombus formation in the left atrium. The aneurysm creates an area of low turbulence leading to haemostasis allowing fibrin-platelet adhesions to form. If the clot is on the left atrial wall, it may be dislodged by oscillations of the septum and travel into the systemic circulation. The second mechanism is via, an often comorbid, interatrial shunt such as a Patent Foramen Ovale or Atrial Septal Defect. We report a unique case where the associated right to left shunt leading to the cryptogenic stroke is a pulmonary arteriovenous malformation.

RESUMO

Aneurysms of the right atrium are rare in the paediatric population. We report a case of a foetal diagnosis of right atrial aneurysm with associated atrial tachycardia in foetal and postnatal life. Unique to our case are the findings of isolated pericardial effusion without hydrops fetalis and the development of aortic coarctation in postnatal life.

RESUMO

Congenital right atrial appendage aneurysm (RAAA) is an extremely rare malformation that can coexist with atrial tachyarrhythmia. There is no consensus on treatment for this condition. This research aimed to investigate the clinical characteristics and efficacy of surgical resection to treat atrial tachyarrhythmia originating from RAAA in children. Four RAAA children diagnosed with atrial tachyarrhythmia at the age of 1-5.25 years weighing 8.3-17.1 kg were discussed in this retrospective study. Patients underwent various treatments, included electrocardiogram (ECG) and echocardiography, antiarrhythmic medication therapy, radiofrequency catheter ablation (RFCA), surgical resection of RAAA and pathological examinations. The results from these treatments along with clinical features of patients were analyzed. The incidence of RAAA in patients with atrial tachycardia originating from the right or left atrial appendages (RAA or LAA) was 7.3% (4/55). The prevalence of RAAA in the RAA was 12.5% (4/32). Atrial tachyarrhythmia was identified both prenatally (26 and 36 weeks of gestational age) and postnatally (1 and 4 months after birth), with two patients per group, respectively. The RAAAs condition in two patients with atrial tachycardia (AT), concomitant atrial flutter (AF) and atrial fibrillation (Af) was identified using echocardiogram. Although, RAAA in two patients with mono AT was unidentified in echocardiogram and failed to be identified in the procedure of RFCA, RAAA was confirmed during surgical resection of the RAA. Multiple pre-surgical antiarrhythmic medications combined therapy used to treat all four patients showed either no effect at all or was only partially effective. The original atrial tachyarrhythmia was successfully abolished after RAAA surgical resection in four patients. AT originating from new foci was established in two patients post-surgically. The conditions of these two patients were successfully reverted and normal sinus rhythm maintained in the application of antiarrhythmic medications. These results confirmed the efficacy of RAAA surgical resection. The pathology study showed cystic dilation in parts of the atrial cavity, fibrosis of the cyst wall, generalized fibrosis of atrial myocardium with myocardium atrophy and cystic dilation. RAAA is prone to misdiagnosis by echocardiogram. Atrial tachyarrhythmia in patients with RAAA is usually resistant to antiarrhythmic medication therapy and RFCA. Surgical resection of RAAA is a safe and effective option that is minimally invasive.

RESUMO

BACKGROUND Response to cardiac resynchronization therapy (CRT) is variable among patients. Extensive scar tissue burden has been characterized as a negative predictor of significant response. Whereas mid-term and long-term response has been thoroughly investigated in randomized clinical trials; however, little is known about acute hemodynamic effects of biventricular pacing. CASE REPORT We report a case of an elderly female patient with severe ischemic cardiomyopathy and a large anterior wall aneurysm, who received right ventricular and biventricular pacing during ablation of incessant pleomorphic ventricular tachycardia. During the procedure, biventricular pacing was associated with a 20% acute increase in systolic blood pressure compared to right ventricular pacing, although there was no acute or long-term effect on left ventricular function. CONCLUSIONS The acute hemodynamic effect of CRT in our patient suggests an effect of CRT even in patients with negative predictors of CRT response such as severe ischemic cardiomyopathy with a large aneurysm. Although no marked increase in left ventricular function might be observed, the acute effect of CRT might contribute to stabilization of heart failure in these patients.

RESUMO

Aorto-mitral discontinuity is considered a relatively rare complication of infective endocarditis, usually requiring invasive surgical procedures, including double valve replacement in addition to aortic root replacement/repair. In the present case report, images were produced using transthoracic echocardiograms and transesophageal echocardiograms, which may assist in the planning of surgical procedures. The images captured using real-time three-dimensional transesophageal echocardiograms revealed aorto-mitral discontinuity and a perforated mitral valve aneurysm of the anterior leaflet.

RESUMO

BACKGROUND: Left ventricular (LV) pseudo-false aneurysm is a rare complication secondary to myocardial infarction and is caused by intramyocardial dissecting hematoma due to fragile myocardium. Very occasionally, intramyocardial dissecting hematoma appears as a neocavitation entirely contained within the myocardial wall (so called "pseudo-false LV") and is an unusual form of subacute cardiac rupture. CASE PRESENTATION: A 38-year-old male experienced chest discomfort 3 weeks ago, which improved within few days. However, after that episode, he presented at our hospital with rapidly deteriorating severe breathlessness in a preshock state with acute heart failure. Emergency coronary angiography revealed an occluded left anterior descending artery. An intra-aortic balloon catheter was inserted because of unstable hemodynamics. Enhanced computed tomography revealed extensive aneurysm formation in the LV anterior wall and contrast leakage from the inner cavity to the LV myocardium, with a moderately accumulated pericardial effusion. Emergency surgery revealed a large aneurysmal sac on the anterior wall, slightly attached to the pericardium. A 5-mm, slit-like, oozing-type, rupture site was detected in the LV after dissecting the pericardium. CONCLUSIONS: To our knowledge, this is the first report of a pseudo-false aneurysm on the LV anterior wall. Subacute rupture of pseudo-false LV aneurysm is rare.

RESUMO

Asian hypertrophic cardiomyopathy (AHCM) is a rare variant of hypertrophic cardiomyopathy (HCM) that is more prevalent in the Asian population. There is significant overlap between AHCM, mid-cavitary obstruction, and apical aneurysms. Although more benign compared to HCM, the course of AHCM is not clearly defined. We present an interesting case of an African American male with known AHCM who develops symptomatic mid-cavitary obstruction and apical aneurysm 11 years after initial diagnosis.

RESUMO

A 74-year-old man was transferred to our hospital for heart failure and ventricular tachycardia. Left ventricular aneurysm of a huge size( 6×9 cm) was found on the imaging test, and was suspected to be a pseudo-false aneurysm because of its thick wall with small orifice. Occulusion of the right coronary artery (#1) was revealed by coronary arteriography and the diskinetic aneurysm in the inferior wall was revealed by left ventriculography. The surgical treatment was needed, because of the high risk of rupture. He successfully underwent Dor operation with endocardial cryoablation and left ventricular ejection fraction (LVEF) was found to be improved by postoperative left ventriculography. He discharged on 56 days after operation. Ventricular pseudo-false aneurysm is rare and the treatment is controversial.

RESUMO

Ten months after an ineffective percutaneous coronary stent placement, a 53-year-old patient was rehospitalized with NYHA functional class IV congestive heart failure, ischemic heart disease and left ventricular aneurysm. Echocardiography revealed thrombus formation in the left ventricle with apical aneurysm. Even though left ventricular assist device (LVAD) implantation improves quality of patients' lives with an increase of its overall use, it becomes more complicated in the presence of ventricular thrombus. We decided to perform ventricular reconstruction with thrombus extraction concomitant to HeartMate 3™ LVAD implantation. The patient was recovered uneventfully, and discharged on postoperative day 14. This report shares the patient's case and the surgical procedure.
