A case report: cardiac dysphagia-a ghost of the past?

ABSTRACT:

Background

Rheumatic heart disease has become rare in developed countries and physicians have grown unfamiliar with the disease and its clinical course. The mitral valve is most commonly affected leading to mitral regurgitation and/or stenosis. The chronic volume and/or pressure overload leads to atrial remodelling and enlargement, driving the development of atrial fibrillation and thrombo-embolic events.

Case summary

A 87-year-old patient with a history of rheumatic mitral stenosis and mitral valve replacement was admitted to the neurology department for vertigo. A stroke was suspected, and she underwent a transoesophageal echocardiogram (TOE) which was complicated by dysphagia. Oesophageal manometry and computed tomography revealed oesophagogastric junction outflow obstruction due to extrinsic compression by a giant left atrium (GLA).

Discussion

Dysphagia due to a GLA is rare. Various diagnostic criteria exist and the prevalence thus depends on which criterium is used. It is mostly encountered in rheumatic mitral disease, although there are reports of non-rheumatic aetiology. When the left atrium assumes giant proportions it can compress adjacent intrathoracic structures. Compression of the oesophagus can lead to dysphagia, as in our case. A TOE in these cases is relatively contraindicated and should only be performed if there is considerable reason to believe that it may change patient management.

Dysphagia as an early sign of cardiac decompensation in elderly: case report.

Project description:BackgroundSeveral clinical entities may be misdiagnosed in elderly if we consider dysphagia as a normal aging process in our daily practice. On top of usual aetiologies like motor dysfunction, investigations may uncover serious underlying conditions.Case summaryWe report an unusual case where dysphagia was the warning sign for acute heart failure in a 76-year-old patient known to have dilated cardiomyopathy with reduced ejection fraction. It was due to an external oesophageal compression by the left atrium. A transthoracic echocardiography, an enhanced thoracic computed tomography-scan and esophagogastroduodenoscopy were used for the diagnosis. Diuretics were the cornerstone treatment with symptomatic improvement.DiscussionDespite the fact that cardiovascular dysphagia is an uncommon medical entity, but it remains a potential differential diagnosis, especially in elderlies with high risk for atrial enlargement.

Esophageal Tuberculosis as a Rare Cause of Dysphagia: Case Report.

Project description:IntroductionThe esophagus and duodenum are rare sites of manifestation for extrapulmonary tuberculosis (TB). Its rarity makes the diagnosis challenging, especially when no other organ is involved, and the endoscopic findings may resemble malignancy.Case presentationWe report a unique case of a 37-year-old woman who presented with dysphagia secondary to esophageal TB with an endoscopic appearance of a submucosal mass resembling malignancy.ConclusionEsophageal TB is a rare cause of dysphagia, especially in a western setting. It should always be considered as a potential etiology in patients with dysphagia.

Multiple chromoanasynthesis in a rare case of sporadic renal leiomyosarcoma: case report

Project description:Renal leiomyosarcomas (LMS) are extremely rare neoplasms with aggressive behaviour and poor survival prognosis. The most frequent somatic events in leiomyosarcomas are mutations in TP53, RB1, ATRX and PTEN genes, chromosomal instability and chromoanagenesis. By using chromosomal microarray analysis we identified monosomy of chromosomes 3 and 11, gain of Xp (ATRX) arm and three chromoanasynthesis regions (6q21-q27, 7p22.3-p12.1 and 12q13.11-q21.2), with MDM2 and CDK4 oncogenes copy number gains, whereas no CNVs or tumor specific SNVs in TP53, RB1 and PTEN genes were observed.

Cardiac mucormycosis: a case report.

Project description:BackgroundMucormycosis is an invasive fungal infection (IFI) most commonly seen in immunocompromised patients. Diabetic ketoacidosis, haematopoietic transplantation, iron overload states, and deferoxamine therapy are considered to be some of the classical risk factors. While cutaneous and rhino-sinusoidal forms may be seen in immunocompetent (IC) individuals, cardiac and mediastinal involvement is rare. In this report, we describe a young patient without predisposing factors who presented as mediastinal mucormycosis with extensive cardiac involvement.Case summaryA 19-year-old male presented with complaints of dry cough and dyspnoea on exertion over the last 4 months. Echocardiography showed diffuse infiltration of both atria along with multiple pedunculated freely mobile masses. A computed tomography chest was done to further delineate the true extent of the disease and revealed diffuse infiltration of the mediastinum, bilateral atria and interatrial septum, pulmonary veins, and superior vena cava. A fine needle aspiration cytology from a mediastinal mass revealed broad aseptate fungal hyphae with right angled branching consistent with Mucor. Extensive evaluation could not find any predisposing factors. The patient was started on Amphotericin B and surgical debridement was contemplated. However, owing to the diffuse infiltration around the heart and mediastinal vasculature, debridement could not be performed and the patient eventually succumbed to the illness.DiscussionMediastinal mucormycosis though rare in IC patients, is a rapidly progressive condition with a high fatality. A high index of suspicion needs to be maintained in individuals presenting with infiltrative disorders of the mediastinum for early diagnosis and prompt treatment.

Surgical treatment of diffuse idiopathic skeletal hyperostosis of cervical spine with dysphagia - Case report.

Project description:Introduction:Diffuse idiopathic skeletal hyperostosis of cervical spine can lead to dysphagia. Presentation of case:A 73-year-old male weighing 110 kg and diagnosed with diffuse idiopathic skeletal hyperostosis in cervical spine with dysphagia. Patient manifested local pain of neck, a gradual limitation of spinal mobility. The surgery decision was based on swallowing problems, not pain in the spine. Before surgery radiographs, magnetic resonance images, computed tomography of the cervical spine and gastroscopy were obtained. Osteophytes were removed from the anterior approach with present otolaryngologist by surgery. Discussion:In this case used gastroscopy, CT and MRI for diagnostics. During the procedure we had support otolaryngologist. The patient has not been found a stenosis spinal canal and neurological symptoms. We were removed the ostheophytes. Interbody implants have not been applied. Conclusion:Disc degeneration disease itself can be asymptomatic or not a dominant problem for the DISH patients. Clinical signs may pharyngoesophageal and tracheal compression, causing dysphagia, shortness of breath and stridor. In this case, the cervical spine was stability and not demonstrated a stenosis in the spinal canal. Isolate removing of the osteophytes without implants in DISH of cervical spine can be enough solution.

Recurrent cardiac myxoma: A case report.

Project description:Cardiac myxomas are the most common benign tumors of the heart. They are most commonly found in the left atrium, followed by a right atrium and rarely in the left ventricle. Herein, we report a rare case of left ventricular myxoma in a patient who had twice undergone removal of left atrial myxoma. Complete removal of the tumor through aortotomy, without causing fragmentation led to the uneventful recovery of the patient.

Primary cardiac lymphoma: a case report.

Project description:BackgroundPrimary cardiac lymphoma is an extremely rare malignancy involving the heart and pericardium. It is a disease that most commonly effects the right atrium and right ventricle. Left untreated it carries a very poor prognosis. Recent advancements in therapy including early recognition and initiation of chemotherapy has led to improved survival.Case summaryA 78 year old female presented with weight loss, abdominal pain and distension. An ultrasound abdomen pre admission showed abdominal ascites. An echocardiogram performed during admission showed a large pericardial effusion with asymmetrical increase in left ventricular wall thickness and a new left atrial mass. Pericardial fluid analysis led to the diagnosis of diffuse large B cell non-Hodgkin's lymphoma. Positron Emission Tomography CT (PET-CT) shows avid fluorodeoxyglucose (FDG) uptake in cardiac muscle. Prompt treatment was initiated with a chemotherapy regimen involving Rituximab, Cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). An echocardiogram 3 months post initiation of treatment showed resolution of the pericardial effusion and left atrial mass as well as an improvement in left ventricular wall thickness. A PET-CT following completion of treatment showed complete metabolic response.DiscussionThe diagnosis of primary cardiac lymphoma is uncommon and the presence of left rather than right heart involvement is rarer still. Multimodality imaging is key in diagnosis. Early recognition and treatment is vital in improving associated morbidity and mortality.
