Coronary vasospasm-induced polymorphic ventricular tachycardia: a case report and literature review.

ABSTRACT: Introduction:Coronary vasospasm is an uncommon but important cause of myocardial ischaemia and ventricular arrhythmias. Case presentation:In this report, we present a striking example of vasospasm manifesting as ST-segment elevation and ventricular tachycardia on Holter monitoring. Later, spasm occurred during a procainamide challenge performed for suspected Brugada syndrome. The patient underwent implantable cardioverter-defibrillator insertion and was successfully treated with oral calcium channel blocker. Discussion:We review contemporary data regarding management and outcomes in coronary vasospasm and discuss the use of implantable defibrillator therapy in patients who have sustained a significant arrhythmic event.

Catecholaminergic polymorphic ventricular tachycardia complicated by dilated cardiomyopathy: a case report.

Project description:BackgroundCatecholaminergic polymorphic ventricular tachycardia (CPVT) is a severe genetic arrhythmogenic disorder characterized by adrenergically induced ventricular tachycardia manifesting as stress-induced syncope and sudden cardiac death. While CPVT is not associated with dilated cardiomyopathy (DCM) in most cases, the combination of both disease entities poses a major diagnostic and therapeutic challenge.Case summaryWe present the case of a young woman with CPVT. The clinical course since childhood was characterized by repetitive episodes of exercise-induced ventricular arrhythmias and a brady-tachy syndrome due to rapid paroxysmal atrial fibrillation and sinus bradycardia. Medical treatment included propranolol and flecainide until echocardiography showed a dilated left ventricle with severely depressed ejection fraction when the patient was 32 years old. Cardiac magnetic resonance imaging revealed non-specific late gadolinium enhancement. Myocardial inflammation, however, was excluded by subsequent endomyocardial biopsy. Genetic analysis confirmed a mutation in the cardiac ryanodine receptor but no pathogenetic variant associated with DCM. Guideline-directed medical therapy for HFrEF was limited due to symptomatic hypotension. Over the next months, the patient developed progressive heart failure symptoms that were finally managed by heart transplantation.DiscussionManagement in patients with CPVT and DCM is challenging, as Class I antiarrhythmic drugs are not recommended in structural heart disease and prophylactic internal cardioverter-defibrillator implantation without adjuvant antiarrhythmic therapy can be detrimental. Regular echocardiographic screening for DCM is recommendable in patients with CPVT. A multidisciplinary team of heart failure specialists, electrophysiologists, geneticists, and imaging specialists is needed to collaborate in the delivery of clinical care.

Proteasome inhibitor-induced coronary vasospasm in multiple myeloma: a case report.

Project description:BackgroundCoronary vasospasm is an increasingly recognized cause of myocardial infarction or myocardial ischaemia in patients without obstructive coronary artery disease. A thorough medication review may identify drugs or toxins that could trigger coronary vasospasm. This case provides mechanistic insight into the off-target effect of proteasome inhibition leading to coronary vasospasm in a patient referred with chest pain consistent with typical angina.Case summaryA 72-year-old lady presented with anginal chest pain at rest with electrocardiogram evidence of myocardial ischaemia who was referred for invasive coronary angiography. This demonstrated minor coronary disease without an obstructive lesion. Vasoreactivity testing revealed diffuse coronary vasospasm of the left anterior descending artery. Carfilzomib was identified as the trigger for coronary vasospasm. Symptoms resolved without recurrence after appropriate treatment including cessation of the triggering agent.ConclusionCoronary spasm is a rare but important adverse reaction to proteasome inhibitors. This case supports the clinical utility of invasive coronary vasoreactivity testing in patients with ischaemia with no obstructive coronary artery disease.

Atropine-induced sinus tachycardia protects against exercise-induced ventricular arrhythmias in patients with catecholaminergic polymorphic ventricular tachycardia.

Project description:AimsCatecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited arrhythmia syndrome characterized by exercise-induced ventricular arrhythmias, sudden death, and sinus bradycardia. Elevating supraventricular rates with pacing or atropine protects against catecholaminergic ventricular arrhythmias in a CPVT mouse model. We tested the hypothesis that increasing sinus heart rate (HR) with atropine prevents exercise-induced ventricular arrhythmias in CPVT patients.Methods and resultsWe performed a prospective open-label trial of atropine prior to exercise in CPVT patients (clinicaltrials.gov NCT02927223). Subjects performed a baseline standard Bruce treadmill test on their usual medical regimen. After a 2-h recovery period, subjects performed a second exercise test after parasympathetic block with atropine (0.04 mg/kg intravenous). The primary outcome measure was the total number of ventricular ectopic beats during exercise. All six subjects (5 men, 22-57 years old) completed the study with no adverse events. Atropine increased resting sinus rate from median 52 b.p.m. (range 52-64) to 98 b.p.m. (84-119), P = 0.02. Peak HRs (149 b.p.m., range 136-181 vs. 149 b.p.m., range 127-182, P = 0.46) and exercise duration (612 s, range 544-733 vs. 584 s, range 543-742, P = 0.22) were not statistically different. All subjects had ventricular ectopy during the baseline exercise test. Atropine pre-treatment significantly decreased the median number of ventricular ectopic beats from 46 (6-192) to 0 (0-29), P = 0.026; ventricular ectopy was completely eliminated in 4/6 subjects.ConclusionElevating sinus rates with atropine reduces or eliminates exercise-induced ventricular ectopy in patients with CPVT. Increasing supraventricular rates may represent a novel therapeutic strategy in CPVT.

Bullet-associated ventricular tachycardia: a case report.

Project description:BackgroundThe majority of ventricular tachycardias (VTs) occurs in patients with structural heart disease and is associated with an increased risk of sudden cardiac death. These VT are scar-related and may develop in patients with ischaemic or non-ischaemic cardiomyopathies.Case summaryWe describe a 44-year-old patient without any pre-existing cardiovascular disease, presenting with the first documentation of a haemodynamically unstable sustained fast VT with a cycle length of 250 ms. He reported a suicidal attempt with a self-made handgun aged 16 when he had shot himself in the thorax and had injured the myocardium. After presenting with the VT coronary artery disease was excluded through cardiac catheterization. A cardiovascular magnetic resonance study showed a localized myocardial scar in the left ventricular free wall starting from the subepicardium and correlating to the scar described 28 years ago by the thoracic surgeons. In an electrophysiological study, non-sustained VT were easily inducible. Presuming a causal relationship between the fast VT and the epicardial scar, a single-chamber implantable cardioverter-defibrillator was implanted and beta-blocker therapy was initiated.DiscussionScar-related VT often occur many years after an acute event, e.g. an acute myocardial infarction. This case highlights, that any cardiac trauma, even a superficial epicardial projectile-related damage with subsequent scarring, may cause a VT after many years and to our knowledge for the first time describes the occurrence of a VT due to mechanical damage to the myocardium by a gunshot.

Diaphragmatic pacemaker-induced ventricular tachycardia leading to cardiac arrest: a case report.

Project description:BackgroundDiaphragmatic pacemakers are used to assist respiration in ventilator-dependent patients. Electromagnetic interference with intrinsic cardiac electrical activity is a theoretical risk but has never been reported in the literature. This case highlights a serious complication of cardiac arrest as a result of diaphragmatic pacing.Case summaryWe report a quadriplegic patient with recent diaphragmatic pacemaker implantation who presented with ventricular tachycardia leading to cardiac arrest. Extensive workup was negative for other aetiologies for ventricular arrhythmias. Reduction of the left-sided diaphragmatic pacemaker voltage resulted in cessation of ventricular ectopy.DiscussionDiaphragmatic pacing at high voltages can cause unwanted transmission of impulses to the cardiac myocytes as a rare complication. This should be noted as a possible complication of intramuscular diaphragmatic pacing, and efforts should be taken to circumvent this risk in the future.

Third Ventricular Glioblastoma Multiforme: Case Report and Literature Review.

Project description:Background Glioblastoma multiforme (GBM) typically presents in the supratentorial white matter, commonly within the centrum semiovale as a ring-enhancing lesion with areas of necrosis. An atypical presentation of this lesion, both anatomically as well as radiographically, is significant and must be part of the differential for a neoplasm in this anatomical location. Case Description We present a case of a 62-year-old woman with headaches, increasing somnolence, and cognitive decline for several weeks. Magnetic resonance imaging demonstrated mild left ventricular dilatation with a well-marginated, homogeneous, and nonhemorrhagic lesion located at the ceiling of the third ventricle within the junction of the septum pellucidum and fornix, without exhibiting the typical radiographic features of hemorrhage or necrosis. Final pathology reports confirmed the diagnosis of GBM. Conclusion This case report describes an unusual location for the most common primary brain neoplasm. Moreover, this case identifies the origin of a GBM related to the paracentral ventricular structures infiltrating the body of the fornix and leaves of the septum pellucidum. To our knowledge this report is the first reported case of a GBM found in this anatomical location with an entirely atypical radiographic presentation.

Case report - coronary vasospasm in transplanted heart: a puzzling phenomenon.

Project description:BackgroundCoronary artery spasm (CAS) is an underdiagnosed disease especially in heart transplant patients, and in those patients the etiology and pathophysiology remain largely unknown, although it has been associated with cardiac allograft vasculopathy or graft rejection.Case presentationWe report the case of a heart-transplant patient whose cardiac graft experienced two coronary vasospasms: the first before transplantation, and the other at one-month of a postoperative course complicated by primary graft failure.ConclusionOur case illustrates that a transplanted heart predisposed with coronary vasospasm may suffer from early relapse in the recipient despite of complete post-surgical autonomic denervation. Exacerbated endothelial dysfunction of the donor heart after transplant, with the addition of systemic factors in the recipient may be involved in the genesis of this puzzling phenomenon.

Ticagrelor-associated ventricular pauses: a case report and literature review.

Project description:BackgroundTicagrelor is an oral anti-platelet agent that is a reversible and direct inhibitor of the adenosine diphosphate P2Y12 receptor. Ticagrelor's brady-arrhythmic potential was investigated in a sub-study of the PLATO trial, which concluded that the effects were transient and not clinically significant beyond the acute initiation phase. Since then, there have been emerging reports of ticagrelor-associated high-degree heart block, requiring drug discontinuation and pacemaker insertion. We present a case of symptomatic ventricular pauses in a patient loaded with ticagrelor post-percutaneous coronary intervention (PCI) for non-ST elevation acute coronary syndrome (NSTEACS) and review the literature relating to ticagrelor and its brady-arrhythmic potential.Case summaryA 59-year-old female presented to our hospital with NSTEACS and received an oral load of ticagrelor 180 mg following PCI to her mid-left circumflex coronary artery. Three hours after, four pauses were observed on telemetry over a 20 min period, the longest being 18.5 s in duration. Ticagrelor was ceased and clopidogrel commenced in place. No arrhythmic events were recorded on loop recorder interrogation following ticagrelor discontinuation.DiscussionThe exact mechanism of ticagrelor-induced brady-arrhythmia is unclear, although inhibition of adenosine reuptake is proposed as likely due to structural similarities between ticagrelor and adenosine. In the setting of acute coronary syndrome treated with ticagrelor, extracellular adenosine concentrations are amplified by the ischaemic milieu with myocardial adenosine release and blunted cellular reuptake. This leads to enhanced agonism of adenosine A1 receptors, causing negative chronotropy and dromotropy. This case report highlights ticagrelor's brady-arrhythmic potential even in the absence of baseline conduction disease or concurrent confounding medications.

A case report of myocardial infarction with non-obstructive coronary artery disease: Graves' disease-induced coronary artery vasospasm.

Project description:BackgroundCoronary artery spasm can occur either in response to drugs or toxins. This response may result in hyper-reactivity of vascular smooth muscles or may occur spontaneously as a result of disorders in the coronary vasomotor tone. Hyperthyroidism is associated with coronary artery spasm.Case summaryA 49-year-old female patient with a 2-day history of intermittent chest pain and electrocardiographic evidence of myocardial ischaemia was referred for emergency coronary angiography. This revealed severe right coronary artery (RCA) and left main (LM) coronary artery ostial vasospasm, both subsequently relieved with administration of multiple doses intracoronary nitroglycerine. Intravascular optical coherence tomography showed absence of atherosclerosis and no evidence of thrombus or dissection confirming the diagnosis of coronary artery vasospasm. Laboratory tests of the thyroid function were performed immediately after coronary angiography revealing Graves' disease as the cause of vasospasm.DiscussionOur case represents a rare presentation of Graves' disease-induced RCA and LM coronary artery ostial vasospasm. In patients with coronary artery vasospasm thyroid function study should be mandatory, especially in young female patients.

Ventricular tachycardia: a presentation of Fabry disease case report.

Project description:BackgroundFabry disease is an inherited rare metabolic disease caused by mutation in the GLA gene, encoding lysosomal enzyme alpha-galactosidase A. The disorder is a systemic disease that manifests as cerebrovascular and cardiac disease, chronic renal failure, skin lesion, peripheral neuropathy, and other abnormalities. Ventricular tachycardia as a Fabry disease presentation is very rare.Case summaryA 36-year-old man self-presented to a general practitioner complaining of episodes of shortness of breath together with a 6-month history of malaise. The 12-lead electrocardiogram (ECG) prompted a decision to transfer him immediately to a percutaneous coronary intervention (PCI) capable hospital under the suspicion of acute coronary syndrome. Whilst awaiting transport, he experienced acute onset of dyspnoea together with non-specific chest heaviness. A repeat ECG monitor strip showed ventricular tachycardia transforming to ventricular fibrillation. The patient was successfully defibrillated. Coronary angiography was performed upon arrival at hospital and demonstrated unobstructed coronary arteries. Transthoracic echocardiography revealed concentric left ventricular hypertrophy (LVH) and normal systolic function, with severe diastolic dysfunction. Magnetic resonance imaging (MRI) confirmed the LVH, and did not demonstrate any late gadolinium enhancement.DiscussionOur case illustrates the pivotal role of critical clinical thinking in the diagnosis of rare but treatable hereditary cardiomyopathy. The uncommon cardiac presentation of Fabry disease promotes further research linking different phenotypes of Fabry disease with different pathogenic mutations.
