Project description:BackgroundRight ventricular mural endocarditis (RVME) is an extremely rare type of infective endocarditis that can occur even in the absence of predisposing factors. The diagnosis is a challenge when no causative pathogen can be detected.Case summaryA previously healthy young man was admitted to a local hospital with a diagnosis of prolonged febrile syndrome and treated for acute sinusitis. As complaints returned, he was hospitalized 3 weeks later, where an echocardiogram demonstrated multiple mobile masses in the right ventricle, and a computed tomography scan revealed extensive pulmonary thromboembolism. During surgery, the endocardial masses were excised, and the pathologist considered an inflammatory myofibroblastic tumour. Despite appropriate medication and initial improvements, the complaints persisted, and 2 weeks after the surgery, the patient returned to the hospital. Imaging studies documented reappearance to the previous findings, whereas blood cultures remained negative. During the second surgery, the new masses resembling vegetations were excised, and histologic analysis indicated infective endocarditis. Adjusted medication was given for 30 days. Just before discharge, no vegetations were seen. At follow-up, 5 years later, he was in a healthy condition.DiscussionDespite careful examinations, initial treatments according to standard protocols were unsuccessful. At final discharge, the patient reported that a tattoo complication prior to the first hospitalization was treated by antibiotics but that he did not complete the course. This omission in the communication further complicated the diagnostic and management processes, leading to surgical interventions that could have been prevented if the neglected antibiotic course was properly disclosed.

Project description:BackgroundCardiac masses include various tumourous and non-tumourous lesions. Primary cardiac tumours are very rare and most commonly benign. Primary cardiac lymphomas (PCL) account for 1-2% of malignant primary cardiac tumours. Only 197 cases of PCL have been reported between 1949 and 2009.Case summaryWe report a case of a 73-year-old patient who presented with atrial flutter. The diagnosis was a tumourous cardiac mass in the right atrium with signs of the infiltration of the tricuspid valve insertion and pericardium. There were no signs of extracardiac disease at the initial presentation. The patient was deemed to be inoperable by cardiac surgeons. Rapid tumour progression caused atrioventricular-block type Mobitz 2 with concomitant obstruction of the tricuspid valve and axillary lymph node metastasizing. Excision of the axillary lymph node revealed a diffuse large B-cell non-Hodgkin lymphoma. An epicardial right ventricle single lead pacemaker was sited, and chemotherapy was administered, resulting in complete remission.DiscussionCardiac masses are rare and challenging cases. Although current imaging procedures deliver extensive information, histological examination is still required in many cases. We encountered a tumourous mass with deep infiltration. After the patient was deemed inoperable, later lymph node invasion allowed histological examination, revealing PCL. Primary cardiac lymphomas are life-threatening tumours with rapid and aggressive growth. Treatment is based on chemotherapy consisting of anthracycline-containing regimens. This case report highlights the curative potential of chemotherapy, as we report a rapid regression of the tumour as well as the disappearance of arrhythmias and conduction disorders after treatment.

Project description:BackgroundCardiac sarcoidosis (CS) and arrhythmogenic right ventricular cardiomyopathy (ARVC) are rare causes of ventricular arrhythmias and are associated with sudden cardiac death. Differentiation between both is important for proper management.Case summaryWe present a 56-year-old man with sudden cardiac arrest and was diagnosed to have ARVC based on cardiac magnetic resonance imaging (MRI). He developed gradually worsening shortness of breath over the next 1 year. CS was unmasked after a cardiac positron emission tomography (PET). Patient was treated with methotrexate. A repeat cardiac PET scan showed improvement.DiscussionThe distinction between ARVC and CS is challenging. Both these entities have a patchy involvement and can have similar presentations. ARVC has a predominant right heart involvement. It is diagnosed with the help of an MRI, which shows regional right ventricular wall motion abnormality. These findings can have an overlap with CS. It is important to note that, even though sarcoidosis is a pathologic diagnosis, cardiac biopsy is rarely done owing to its patchy involvement. Cardiac PET scan has a high sensitivity and specificity to diagnose this entity. Once diagnosis is made, patients should be treated with immunosuppressants and should be closely followed. Repeat imaging should be considered at intervals to monitor disease progression. This case highlights the importance of multimodality imaging and tissue diagnosis to unmask the diagnosis of CS, a treatable infiltrative disorder which shares features with a potentially untreatable ARVC.

Project description:Introduction and significanceCardiac dissemination of gastric adenocarcinoma represents an exceedingly uncommon clinical scenario. To date, there is an absence of documentation concerning the presence of tumor emboli within the cardiac chambers originating from gastric cancer, particularly following a possible transvenous migration.Case presentationThis report delineates the clinical journey of a 60-year-old female diagnosed with inoperable diffuse gastric adenocarcinoma, who developed cardiac metastases.Clinical discussionThe prognostication of isolated cardiac metastasis in oncology patients is fraught with difficulty due to its infrequency and non-specific clinical manifestations. While systematic screening for cardiac metastasis is not part of standard oncological protocols, heightened vigilance is warranted in specific scenarios such as advanced-stage malignancies or in the presence of suggestive cardiac symptomatology, thereby prompting further exploration.ConclusionCardiac metastasis, while infrequent, constitutes a dire clinical entity that must be contemplated in the differential diagnosis of cardiac mass presentations in individuals with a neoplastic history. Prompt recognition and deployment of appropriate diagnostic imaging are pivotal for informed therapeutic decision-making. An integrative, multidisciplinary strategy is imperative for the formulation of an optimal treatment paradigm, encompassing surgical and palliative care options.Key clinical messageCardiac metastasis of gastric adenocarcinoma are extremely rare, however, in gastric cancer cases with cardiopulmonary manifestation should be considered as a probable differential diagnoses.

Project description:BackgroundRight ventricular failure (RVF) is a leading driver of morbidity and death after major cardiac surgery for advanced heart failure, including orthotopic heart transplantation and left ventricular assist device implantation. Inhaled pulmonary-selective vasodilators, such as inhaled epoprostenol (iEPO) and nitric oxide (iNO), are essential therapeutics for the prevention and medical management of postoperative RVF. However, there is limited evidence from clinical trials to guide agent selection despite the significant cost considerations of iNO therapy.MethodsIn this double-blind trial, participants were stratified by assigned surgery and key preoperative prognostic features, then randomized to continuously receive either iEPO or iNO beginning at the time of separation from cardiopulmonary bypass with the continuation of treatment into the intensive care unit stay. The primary outcome was the composite RVF rate after both operations, defined after transplantation by the initiation of mechanical circulatory support for isolated RVF, and defined after left ventricular assist device implantation by moderate or severe right heart failure according to criteria from the Interagency Registry for Mechanically Assisted Circulatory Support. An equivalence margin of 15 percentage points was prespecified for between-group RVF risk difference. Secondary postoperative outcomes were assessed for treatment differences and included: mechanical ventilation duration; hospital and intensive care unit length of stay during the index hospitalization; acute kidney injury development including renal replacement therapy initiation; and death at 30 days, 90 days, and 1 year after surgery.ResultsOf 231 randomized participants who met eligibility at the time of surgery, 120 received iEPO, and 111 received iNO. Primary outcome occurred in 30 participants (25.0%) in the iEPO group and 25 participants (22.5%) in the iNO group, for a risk difference of 2.5 percentage points (two one-sided test 90% CI, -6.6% to 11.6%) in support of equivalence. There were no significant between-group differences for any of the measured postoperative secondary outcomes.ConclusionsAmong patients undergoing major cardiac surgery for advanced heart failure, inhaled pulmonary-selective vasodilator treatment using iEPO was associated with similar risks for RVF development and development of other postoperative secondary outcomes compared with treatment using iNO.RegistrationURL: https://www.Clinicaltrialsgov; Unique identifier: NCT03081052.
