Project description:A 55-year-old former professional athlete reported out of proportion dyspnea on exertion. After a detailed cardiac investigation, a cardiopulmonary exercise test on an ergocycle demonstrated an abnormal and non-physiological ventilatory response characterized by a sharp rise in ventilation followed by a decrease while exercise workload was progressively increasing. This was accompanied by noisy breathing. A laryngoscopy with direct visualisation of larynx and vocal cord during voluntary eucapnic hyperventilation confirmed the diagnosis of exercise-induced laryngeal obstruction. The patient was treated with speech therapy and all the symptoms resolved. A second cardiopulmonary exercise test showed a normalisation of the ventilatory pattern during exercise. This case demonstrates the importance of recognizing the symptoms of an exercise-induced laryngeal obstruction regardless of age, and the effectiveness of the speech therapy on symptoms and on exercise testing.

Project description:BackgroundThe use and utility of novel oral anticoagulants has been increasing in clinical practice due to their relatively lower incidence of side effects such as intracranial haemorrhage, particularly in the elderly, when compared with vitamin K antagonists. Rivaroxaban is a factor Xa and prothrombinase inhibitor indicated for stroke and venous thromboembolism prophylaxis in non-valvular atrial fibrillation as well as treatment of venous thromboembolism.Case summaryA patient with history of paroxysmal atrial fibrillation on Rivaroxaban presented with generalized malaise, lightheadedness, and dizziness. The patient was found to be in profound cardiogenic shock despite unremarkable cardiac enzymes. Electrocardiogram revealed rate controlled atrial fibrillation and T-wave inversions in the inferolateral leads without associated electrical alternans. Bedside echocardiogram revealed a large pericardial effusion consistent with cardiac tamponade physiology. Following anticoagulation reversal, the patient underwent urgent pericardiocentesis yielding haemorrhagic fluid, with subsequent improvement in haemodynamic status. Despite the presence of retroperitoneal lymphadenopathy on previous computed tomography of the abdomen and concern for underlying malignant effusion secondary to lymphoma, cytology of the fluid revealed no evidence of malignant cells and follow-up flow cytometry and bone marrow biopsy were unremarkable.DiscussionWhile hemopericardium is not listed as a known side effect of Rivaroxaban, previous cases of hemopericardium secondary to Rivaroxaban have been described in the literature secondary to pre-disposing risk factors including CYP450 drug interactions or cardiac device implantations. In this case, the patient experienced a spontaneous hemopericardium on Rivaroxaban without any previously elucidated risk factors or evidence of malignancy.

Project description:BackgroundAtrial dissociation (AD) is described as the existence of two simultaneous electrically isolated atrial rhythms. Theoretically, detection of dual atrial rhythms with a sufficiently high rate by pacemaker can lead to automatic mode switching and associated pacemaker syndrome. Such a clinical observation has not been reported before in the literature.Case summaryAn 87-year-old female with Ebstein's anomaly status post-tricuspid valve annuloplasty and tricuspid valve replacement and a dual-chamber pacemaker presented with congestive heart failure 1 week after undergoing atrial lead revision. Interrogation of her dual-chamber pacemaker revealed two atrial rhythms: sinus or atrial-paced rhythm and electrically isolated atrial tachycardia (AT). Sensing of both atrial rhythms by the pacemaker led to automatic mode switching, which manifested as ventricular paced rhythm with retrograde P waves on electrocardiogram. Adjusting the atrial lead sensitivity to a level higher than the sensing amplitude of AT restored atrial paced and ventricular sensed rhythm, which resulted in resolution of heart failure symptoms.DiscussionRegardless of the cause of AD, there must be electrical insulation between the two rhythms for their independent coexistence in the atria. Atrial dissociation can lead to pacemaker syndrome from automatic mode switching. If the sensing amplitude during sinus rhythm is significantly larger than that of AT, adjusting the atrial lead sensitivity would solve the issue, as in the present case. Otherwise, atrial lead revision, pharmacotherapy, or AT ablation should be considered.

Project description:We describe a case of an 88-year-old woman with a severe bluntly ematic pericardial effusion. Radiological and laboratory examinations excluded all the most common causes of hemopericardium, and the diagnosis of spontaneous hemopericardium associated with the treatment with rivaroxaban was made. This is the first case report describing a hemopericardium in a patient treated with rivaroxaban who did not take other herbal products or drugs that may significantly increase rivaroxaban blood levels. This report emphasizes the need for the careful use of new oral anticoagulants, and the importance of taking in mind uncommon side effects. Spontaneous hemopericardium should be considered in these patients.

Project description:Syncope commonly results in emergency room and physician visits, leading to hospitalization and invasive investigations. Up to 24% of these presentations may be caused by neurogenic orthostatic hypotension (nOH), which continues to be an under-recognized clinical entity. We review an approach to diagnosing nOH. An 85-year-old man with a history of Parkinson's disease was referred for a history of recurrent syncope, which had resulted in extensive cardiac investigation. Collateral history revealed that the events were orthostatic in nature, but with variable time to onset of symptoms. The patient was found to have significant postural drop in blood pressure without compensatory tachycardia. Cardiovascular autonomic function testing was performed, which confirmed significant autonomic nervous system failure, including a marked hypotensive response on tilt-table testing and a lack of vasoconstriction during Valsalva manoeuvre. The patient was diagnosed with nOH and initiated on midodrine with subjective improvement in the frequency of syncope. Autonomic nervous system failure, with nOH, is a common cause of recurrent syncope, particularly in older patients. Attention to detail during the medical history, including precipitating factors and the presence of prodromal symptoms prior to syncope, is critical for making the correct diagnosis. Measuring orthostatic vital signs correctly in patients with syncope provides valuable information, is cost-effective, and critical to diagnose nOH.

Project description:BackgroundThe presence of a persistent fibrous sheath in right-sided heart chambers after transvenous lead extraction has already been described in some studies as echocardiographic tubular mobile masses called 'ghosts'. Their presence has been associated with cardiac device-related infective endocarditis or local device infection, but to the best of our knowledge, this is the first case where 'ghosts' have been reported among non-infected patients.Case summaryWe present a case of a 73-year-old woman hospitalized due to worsening dyspnoea and a significant pericardial effusion, relapsed after pericardiocentesis with removal of about 1500 mL of non-haemorrhagic fluid. The patient's history revealed a previous dual-chamber pacemaker implantation due to symptomatic sick sinus syndrome. Transoesophageal echocardiography (TOE), essential to exclude endocarditis vegetations suggested an etiopathogenesis of mechanical irritation caused by the distal end of the passive fixation atrial lead on the right atrial appendage wall. Considering the echocardiographic report and the condition of reactive pericarditis with the early relapse of the significant pericardial effusion after pericardiocentesis, we opted for a lead removal procedure to eliminate the stimulus causing the irritation, with transoesophageal echocardiographic monitoring, thus the early detection of a 'ghost' was possible.DiscussionThis is the first clinical case describing the presence of fibrin 'ghosts' sometime after the implantation of a pacemaker, highlighting a non-exclusively infectious genesis, and emphasizing the importance of TOE for the early detection of this post-extraction complication and its monitoring.

Project description:BackgroundSystemic lupus erythematosus (SLE) is an autoimmune disease, frequently associated with cardiovascular involvement. One of the most frequent complication is mitral valve regurgitation in more than one-third of the patients.Case summaryA 30-year-old woman with arthralgia, butterfly rash, and Raynaud phenomenon presented with a systolic murmur and renal impairment. Based on the kidney biopsy the diagnosis of SLE was made. Echocardiography revealed the presence of pulmonary hypertension, restrictive mitral valve disease with nodular thickening of the anterior leaflet and moderate regurgitation, compatible with Libman Sacks (LS) endocarditis. Immunosuppressive therapy was started and the patient status improved with normalization of systolic pulmonary artery pressure. After 8 years without follow-up, she presented with fatigue and dyspnoea based on a severe mitral valve stenosis. Subsequently, she underwent a minimal invasive mitral valve replacement and the diagnosis of LS endocarditis could be confirmed upon histopathological examination.DiscussionThis case demonstrates that LS endocarditis can not only lead to mitral regurgitation but occasionally to mitral stenosis due to chronic inflammation with thickening and fusion of mitral valve leaflets. Hereby, comprehensive echocardiography, inclusive stress echocardiography, plays a critical role.

Project description:IntroductionAggregatibacter aphrophilus (formerly Haemophilus aphrophilus and H. paraphrophilus) is classically associated with infective endocarditis. Other infections reported in the literature include brain abscess, bone and joint infections and endophthalmitis. There are only two cases of empyema ever reported due to this organism. We report the isolation of A. aphrophilus from pleural fluid on three separate hospital admissions in a patient with recurrent empyema.Case presentationA 65-year-old female patient of Caucasian origin presented with a three-week history of fever, shortness of breath and dry cough. She was found to have a pleural empyema so a chest drain was inserted and a sample of pus was sent to the microbiology laboratory. After overnight incubation, a chocolate blood agar plate incubated in 5% carbon dioxide showed a profuse growth of small, round, glistening colonies which were identified as Gram-negative coccobacilli. They were oxidase- and catalase-negative. Biochemical testing using RapID NH confirmed the identity of the organism as A. aphrophilus. It was susceptible to amoxicillin, levofloxacin and doxycycline. Our patient was treated with intravenous amoxicillin with clavulanic acid and clarithromycin followed by oral doxycycline, but was re-admitted twice over the next three months with recurrent empyema and the same organism was isolated. Each episode was managed with chest drainage and a six-week course of antibiotic--doxycycline for the second episode and amoxicillin for the third episode, after which she has remained well.ConclusionThis is the first case report of recurrent empyema due to A. aphrophilus. Our patient had no underlying condition to explain the recurrence. Although our isolate was doxycycline susceptible, our patient had recurrent infection after treatment with this antibiotic, suggesting that this antibiotic is ineffective in treatment of deep-seated A. aphrophilus infection. This organism can be difficult to identify in the laboratory because, unlike closely related Haemophilus spp., it is oxidase-negative, catalase-negative and X and V independent.

Project description:BackgroundRecurrent vasospastic angina sometimes occurs. Fresh thrombi have been known to arise without plaque rupture at coronary spasm sites due to blood flow stagnation and intimal erosion caused by vasospasms. The relationship between recurrence of vasospastic angina and thrombus formation remains unclear.Case summaryA 67-year-old man presented with sudden chest pain at rest. Electrocardiography and coronary angiography indicated vasospastic angina. His chest pain persisted despite the administration of benidipine, isosorbide mononitrate, nicorandil, and nifedipine. Coronary angiography performed one month after initial presentation showed stenosis refractory to isosorbide administration. Optical coherence tomography revealed a healed plaque, and a stent was deployed. The patient remained symptom-free at 1-year follow-up.DiscussionProlonged coronary vasospasm with limited coronary blood flow could induce total occlusion of the coronary artery, and acute thrombus formation, which resulted in healed plaque erosion. When vasospastic angina cannot be controlled, rapidly progressive stenosis caused by healed plaque erosion could be its underlying cause and mechanism. This report indicates that antiplatelet therapy may be a preventive option for future recurrent vasospastic angina, especially in those caused by healed plaques.

Project description:In literature it has been reported in 1998, for the first time, a case of a 54-year-old man who developed constrictive pericarditis (CP) 12 years after diagnosis of dermatomyositis (DM). To our knowledge, this may be the only case reported. A 16-year-old man presented to our institution because of symptoms posing a suspicion for an inflammatory disease; after physical examination, lab tests, and other investigations (electromyography, magnetic resonance, and muscular biopsy) was diagnosed as having DM. Patient also showed hepatomegaly and congested jugular veins: after clinical and imaging investigations (transthoracic echocardiography and transoesophageal echocardiography) he was diagnosed as having a CP. Patient underwent pericardial resection and the final outcome consisted of a completely regression of the symptoms. Cardiac involvement in patients with DM ranges between 6% and 75%, and it can be clinically manifest or, far more frequently, sub-clinic. Pericardial involvement as a complication of DM is widely reported in the literature, but in almost all cases as acute pericarditis, effusive pericarditis or cardiac tamponade and almost never as a CP.
