Giant left ventricular pseudoaneurysm: a rare acute complication of radiofrequency catheter ablation for premature ventricular contraction.

Project description:BackgroundRadiofrequency 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 presentationA 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.ConclusionsIt 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.

Case report: Artery of Percheron infarction as a rare complication during atrial fibrillation ablation.

Project description:The incidence of stroke or transient ischemic attacks (TIA) in atrial fibrillation (AF) catheter ablation procedures is around 1% and may be unnoted under anesthesia. The artery of Percheron (AOP) infarction is a rare kind of stroke with heterogeneity in manifestation, which further makes the perioperative early detection and diagnosis a challenge. Herein, we present one patient who underwent AF ablation and presented mental status alteration after withdrawing anesthetics. An emergency head CT was obtained, which revealed no apparent pathological changes. A late MRI test confirmed the diagnosis of AOP infarction. With oral anticoagulants and rehabilitation therapies, the patient's awareness improved and fully recovered on the sixth-month follow-up. Variability in manifestation, no positive radiological finding on initial CT, and a low incidence has made few clinicians to gain much experience with this type of infarct, which delays the diagnosis and initiation of appropriate treatment.

Extensive pulmonary venous stenoses as a complication of radiofrequency catheter ablation for atrial fibrillation.

Project description:Although pulmonary veins stenosis (PVS) is a well documented complication of radiofrequency-catheter ablation (RFCA) of atrial fibrillation (AF), simultaneous involvement of multiple PVs is extremely rare. We present the case of a 69 years-old male patient, with prior medical history of persistent AF, who had been treated with RFCA two years ago. After RFCA, he started with shortness of breath and needed hospitalization for bilateral pneumonia. One year after the procedure, he was on home oxygen, but still referred dyspnea, cough and hemoptysis. A transthoracic echocardiogram showed moderate right ventricular (RV) systolic dysfunction and elevated RV systolic pressure. Dedicated cardiac tomography for PV assessment revealed severe narrowing and pre-stenotic engorgement of all 5 PVs, with subtotal ostial occlusion of both the left lower and right middle PVs. PV angiography confirmed the diagnosis. Only the left and right upper PV were able to be wire-crossed and stented, with substantial reductions in stenosis from 90 % to 10 %. After 3 months of follow-up, the patient improved substantially, and home O2 was withdrawn.

Case of maxillary actinomycotic osteomyelitis, a rare post COVID complication-case report.

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.

Regional pericarditis following uncomplicated catheter ablation procedure: a case report.

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.
