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: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: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.

Project description:BackgroundSince late 2019, the outbreak of COVID-19 has rapidly spread worldwide. As it is a newly emerged disease, many of its manifestations and complications are unknown to us. Cardiac involvement and arrhythmias are another aspect of the disease about which very little is known.Case summaryA 71-year-old male patient presented at the Emergency Department complaining of fever, a dry cough, and dyspneoa. He was admitted due to these symptoms suggestive of COVID-19, and a chest CT and PCR test confirmed the diagnosis. During admission, cardiac involvement was detected, i.e. second-degree atrioventricular block with intermittent left bundle branch block (LBBB) which progressed to fixed LBBB and eventually developed into atrial fibrillation/flutter with bradycardia. Both cardiac troponin and echocardiographic findings for detecting myocarditis were negative. We waited 14 days for resolution of atrioventricular block before permanent pacemaker implantation, but the condition still did not improve after the waiting period.DiscussionCOVID-19 is mainly a respiratory infection but cardiac involvement is not uncommon in the course of the disease. Arrhythmia, during this infection, seems to be caused by an inflammatory response in the myocardium, electrolyte disturbances, and hypoxia; the course of the disease in our case study shows that the virus can preferentially and irreversibly involve the cardiac conduction system.

Project description:Introductionand Importance: Post-operative pancreatic fistula is a morbid complication after pancreaticoduodenectomy. Though most of them present in the immediate post-operative period, few case reports have mentioned it even 7 years after index surgery. Here, we report a delayed presentation of pancreatic fistula 6 months after surgery.Case presentationA 57 year old female underwent Whipple's pancreaticoduodenectomy for pancreatic head adenocarcinoma and was discharged with an uneventful post-operative recovery. She presented after 6 months with complaints of abdominal pain and distension which upon evaluation was found to be a pancreatic enzyme rich mutiloculated collection. It was managed with per-cutaneous drain placement.Clinical discussionPancreatic fistula remained a major cause of morbidity and mortality even after 100 years of its existence. It can be overt fistula which manifest in the immediate post-operative period or occult fistula which manifests long after primary surgery. Various causes of delayed fistula are anastomotic site stricture, previous chemotherapy, infection. The management options available are percutaneous drainage, endoscopic stenting of anastomotic stricture or redoing the anastomosis.ConclusionPancreatic fistula can have a delayed presentation which can be diagnosed and managed with regular follow up.
