Project description:BACKGROUND:Radiofrequency catheter ablation is approved effective therapy for premature ventricular contraction. However, the rare but serious complication such as pseudoaneurysm should be given more attention. It is life-threatening due to the high risk of rupture. Only few cases have been reported in the literature. We herein report a huge acute left ventricular pseudoaneurysm after catheter ablation therapy. CASE PRESENTATION:A 69-year-old man underwent radiofrequency catheter ablation for premature ventricular contraction at a local hospital. The patient developed shock the second day after ablation. A chest computed tomography (CT) scan showed pericardial effusion. Pericardiocentesis was performed, and the puncture fluid was a bloody pericardial effusion. The transthoracic echocardiogram revealed an 9-?×?4-cm giant pseudoaneurysm with a cystic structure in the left ventricular inferior wall near the mitral annulus along the left atrium. The pseudoaneurysm was connected to the left ventricular cavity through a 8-mm neck, and the lumen was filled with systolic and diastolic blood flow. The patient underwent three-dimensional transesophageal echocardiography. The pseudoaneurysm and the tract was clearly visible. Emergency surgery was performed to resect the pseudoaneurysm. A bovine pericardial patch was placed on the neck of the pseudoaneurysm. Echocardiographic examination confirmed the absence of cardiac lesions after the operation. CONCLUSIONS:It is rare to see such a large pseudoaneurysm after radiofrequency catheter ablation. Clinicians should be allert to the potential risks to patients in the process of an effective treatment. Echocardiography plays an important role in the prompt diagnosis and prognosis of this disease. Emergency surgery is a better method for treatment of huge pseudoaneurysm.
Project description:Introductionand Importance: Maxillary actinomycosis is a persistent, very rare disease produced by Actinomyces species which may include only soft tissue or bone or the two together. Actinomycotic osteomyelitis of maxilla is very infrequent when compared to mandible.Case presentationHere we are conferring a case of an elderly male patient who had history of COVID-19 infection 4 months ago, with constant complaint of non-remitting vague pain in the region of maxilla with tooth loosening and extractions. He was given a provisional diagnosis of chronic osteomyelitis of maxilla which was later on proved by histopathology as actinomycotic osteomyelitis.Clinical discussionA saprophytic fungus causes mucor mycosis, and it is quite unusual. Strawberry gingivitis is one of the signs and symptoms. Mucormycosis and post-covid oral maxillofacial problems can be improved with early diagnosis. Oral Mucormycosis should be suspected in individuals with weakened immune systems, uncontrolled diabetes or post-covid instances. Surgery and adequate antibiotic treatment are necessary to treat actinomycosis. Infection may return after a period of inactivity, so long-term follow-up is necessary.ConclusionWe conclude a positive causal association between COVID-19 and actinomycosis. Maxillary osteomyelitis, a very rare infection, and in our case, the causative organism was Actinomyces Patients who have been infected should be tested for Actinomycin, which may masquerade as a head and neck illness.
Project description:BackgroundAcute post-ablation pericarditis is the most common complication of epicardial ablation of ventricular arrhythmias, while regional pericarditis following an initially uneventful endocardial catheter ablation (CA) procedure is a rare and elusive diagnosis.Case summaryWe report a case of a 66-year-old Russian female who developed chest pain accompanied by electrocardiogram (ECG) changes-biphasic T waves in V1-V4 leads after an initially uncomplicated premature ventricular complex CA procedure. After examination and investigations, including transthoracic echocardiography (TTE), cardiac magnetic resonance imaging (CMR) and cardiac computed tomography (CCT), she was diagnosed with regional pericarditis, which occurred even though the ablation was uneventful with the limited number of radiofrequency applications. Furthermore, the diagnosis was difficult due to normal body temperature and the absence of pericardial effusion and myocardial abnormalities on TTE, findings that are not characteristic of pericarditis. The patient's last office visit was in 6 months after the procedure. Neither patient had any complaintsnor there were any changes on ECG and TTE.DiscussionRegional post-ablation pericarditis is a relatively rare type of post-cardiac injury syndrome (PCIS). The varying severity of the PCIS clinical course makes the diagnosis of post-ablation pericarditis initially difficult, especially in patients undergoing an uneventful CA procedure. Non-invasive imaging modalities as CMR and CCT should be considered initially in elusive cases of PCIS.
Project description:A 25-year-old male patient with highly symptomatic, monomorphic, premature ventricular contractions presented for repeat ablation after failed endocardial ablation. Three weeks after excessive endocardial and epicardial ablation on the left ventricular summit, the patient was admitted again with tamponade following a pseudoaneurysm on the ablation site. (Level of Difficulty: Advanced.).
Project description:BackgroundTicagrelor is a widely used P2Y12 inhibitor and represents a fundamental therapeutic agent in acute coronary syndrome treatment and selected post-percutaneous coronary intervention (PCI) cases. Dyspnoea and bradycardia are the most common side effects but the latter has been reported to be of trivial clinical significance.Case summaryA 51-year-old gentleman underwent PCI to left anterior descending and obtuse marginal for unstable angina receiving a loading dose of ticagrelor (180 mg). During hospital stay, whilst on telemetry monitoring, a 16 s long, symptomatic, asystolic ventricular standstill was recorded prompting ticagrelor interruption and a switch to prasugrel.DiscussionDespite ventricular pauses have been reported in dedicated analyses of Phase III trials, no apparent clinical consequences were documented. However, several reports have shown that significant brady-arrhythmic events might be linked to ticagrelor administration presenting both as sino-atrial and atrio-ventricular conduction disturbances. We report a case of asystole occurring 36 h after the administration of a loading dose.
Project description:Le Fort I osteotomy is a frequent surgical procedure used in orthognathic surgeries to treat severe malocclusions and is associated with relatively rare surgical complications. Here, the authors report a case of thrombotic ischemic stroke as a result of this procedure, a complication still not described in the literature. A 19-year-old man with class II malocclusion and retrognathia underwent orthognathic surgery for aesthetic purposes. The surgery included a Le Fort I maxillary osteotomy with vertical impaction, bilateral sagittal split ramus osteotomy for mandibular advancement, and genioplasty. Postoperatively, the patient developed left eye blindness, headache, somnolence, aphasia, and right hemiplegia. Medical imaging showed the Le Fort I line of fracture extending from the maxillary osteotomy to the left optic canal and to the left carotid canal, with osseous fragments impinging the petrous segment of the internal carotid artery, left carotid artery occlusion and associated to an ischemic stroke at the left middle cerebral artery territory. Treatment required decompressive craniectomy and later focused on clinical stabilization, infection management, orthognathic care, neurorehabilitation, and cranioplasty. The hemiplegia and aphasia partially recovered during 12 months, and final dental occlusion was appropriate. Our report demonstrates that an unfavorable Le Fort I fracture trajectory can lead to ischemic stroke and severe neurological deficits.
Project description:BackgroundAtrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular arrhythmia that is frequently encountered in an otherwise healthy patient population. Recent guidelines of the European Society of Cardiology underline the role of catheter ablation in the long-term management of these patients.Case summaryThis case describes the clinical presentation and treatment options in a patient with typical slow/fast AVNRT, the most common subform of AVNRT, where antegrade conduction occurs over the slow pathway and retrograde conduction over the fast pathway. The ablation strategy in these patients is illustrated based on intracardiac recordings in combination with per-procedural three-dimensional imaging.DiscussionAtrioventricular nodal reentrant tachycardia is a common arrhythmia with good prognosis but significant impact on quality of life of affected patients. Catheter ablation should be considered early as it can be performed safely and with a very high success rate.
Project description:A 9-year-old girl with a ten-day history of palpitations was referred for the assessment of mitral regurgitation. She had had RF ablation for paroxysmal supraventricular tachycardia 5 years previously. Echocardiography showed isolated anterior mitral leaflet perforation. Surgical findings confirmed the echocardiographic assessment.
