Abstract
Implantable cardiac defibrillators are a key component in preventing sudden cardiac death for patients with life-threatening arrhythmias. Through ageing, frailty and the progression of cardiac and non-cardiac morbidity, many will develop a 'life-limiting' condition. This raises the challenge of how to approach making decisions to deactivate the defibrillator function. This article discusses the background to deactivation of implantable cardioverter defibrillators and the practical considerations for different circumstances.

Abstract
BACKGROUND Reverse Takotsubo cardiomyopathy is characterized by transient myocardial hypokinesia affecting predominantly the basal myocardial wall. It is a rare variant of Takotsubo cardiomyopathy affecting younger patients. CASE REPORT We report a case of a young man who having consumed methamphetamines presented with cardiogenic shock and severe left ventricular systolic dysfunction, affecting predominantly the basal segments with sparing of the apex. After inotropic support, the left ventricular ejection fraction improved. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important that emergency physicians are aware of the danger of methamphetamine consumption, and how it can lead to potentially fatal acute cardiac syndromes, including reverse Takotsubo cardiomyopathy and cardiogenic shock.

Abstract
AIMS CT calcium scoring (CTCS) and CT cardiac angiography (CTCA) are widely used in patients with stable chest pain to exclude significant coronary artery disease (CAD). We aimed to resolve uncertainty about the prevalence of obstructive coronary artery disease and long-term outcomes in patients with a zero-calcium score (ZCS). METHODS AND RESULTS Consecutive patients with stable cardiac symptoms referred for CTCS or CTCS and CTCA from chest pain clinics to a tertiary cardiothoracic centre were prospectively enrolled. In those with a ZCS, the prevalence of obstructive CAD on CTCA was determined. A follow-up for all-cause mortality was obtained from the NHS tracer service. A total of 3914 patients underwent CTCS of whom 2730 (69.7%) also had a CTCA. Half of the patients were men (50.3%) with a mean age of 56.9 years. Among patients who had both procedures, a ZCS was present in 52.2%, with a negative predictive value of 99.5% for excluding ≥70% stenosis on CTCA. During a mean follow-up of 5.2 years, the annual event rate was 0.3% for those with ZCS compared with 1.2% for CS ≥1. The presence of non-calcified atheroma on CTCA in patients with ZCS did not affect the prognostic value (P = 0.98). CONCLUSION In patients with stable symptoms and a ZCS, obstructive CAD is rare, and prognosis over the long-term is excellent, regardless of whether non-calcified atheroma is identified. A ZCS could reliably be used as a 'gatekeeper' in this patient cohort, obviating the need for further more expensive tests.

Abstract
Sarcoidosis is a multi-system disease with a wide range of phenotypes. Pulmonary involvement is the most frequently identified target for sarcoidosis and is responsible for the majority of deaths. Cardiac sarcoid is less commonly identified, may be occult, is significantly influenced by race, and can portend an unpredictable and sometimes fatal outcome. Sarcoidosis remains an enigmatic disease spectrum of unknown aetiology, frequently difficult to diagnose and with a variable disease course. This article summarises current views on the diagnosis and management of cardiopulmonary involvement.

Abstract
Sarcoidosis is a multisystem inflammatory disease, the aetiology of which has still to be resolved. The proposed mechanism is that a susceptible genotype is exposed to one or more potential antigens. A sustained inflammatory response follows, which ultimately results in pathognomonic granuloma formation. Various clinical phenotypes exist with specific genetic associations influencing disease susceptibility, protection, and clinical progression. Occupational and environmental factors, including microbial elements, may then effect the development of this disease. Sarcoidosis is a heterogeneous disease, showing geographic and racial variation in clinical presentation. It demonstrates a familial tendency and clear genotype associations. Additionally, it appears to cluster within closely associated populations (eg, work colleagues) and appears to be related to selected occupations and environmental exposures. Frequently occult, but occasionally fatal, this disease has a very variable prognosis. It is also unusual in having no specific biomarker. The epidemiology and multiple factors that appear to influence the aetiology of sarcoidosis illustrate why this disease state is frequently described as a clinical enigma.

Abstract
There are two forms of transthyretin (TTR) amyloidosis: non-hereditary and hereditary. The non-hereditary form (ATTRwt) is caused by native or wild-type TTR and was previously referred to as senile systemic amyloidosis. The hereditary form (ATTRm) is caused by variant TTR which results from a genetic mutation of TTR. The predominant effect of ATTRwt amyloidosis is on the heart, with patients having a greater left ventricular wall thickness at presentation than the devastating form which is light chain (AL) amyloidosis. ATTRm amyloidosis is broadly split into two categories: a type that predominantly affects the nervous system (often called familial amyloid polyneuropathy (FAP)) and one with a predilection for the heart (often called familial amyloid cardiomyopathy (FAC)). Approximately half of all TTR mutations known to express a clinical phenotype cause a cardiomyopathy. Since the introduction of orthotopic liver transplantation for ATTRm amyloidosis in 1991, several additional therapies have been developed. These therapies aim to provide a reduction or elimination of TTR from the plasma (through genetic approaches), stabilisation of the TTR molecule (to prevent deposition) and dissolution of the amyloid matrix. We describe the latest developments in these approaches to management, many of which are also applicable to wild-type amyloidosis.

Abstract
A 37-year-old woman presented with a 2-week history of persistent headache in an occipitotemporal distribution. The patient had experienced prior headaches and migraines, but this presentation was characterised by its intensity and duration. There was associated dizziness and blurring of vision in episodes occurring up to 4-5 times per day. Whole body cross-sectional CT imaging and MRI of neuronal axes were normal. Cerebrospinal fluid cytology demonstrated large abnormal pleomorphic cells expressing the tumour marker CA125. Positron emission tomography-fluorodeoxyglucose revealed bilateral axillary and cervical lymphadenopathy as well as increased uptake in the lateral regions of both breasts. These results correlated with MRI breast and mammography findings. Axillary lymph node biopsy showed poorly differentiated adenocarcinoma making the diagnosis of breast malignancy, the most likely primary site of metastatic leptomeningeal disease. In the 6-week interval between initial presentation and diagnosis, the patient deteriorated significantly with the new onset of facial nerve palsy and partial seizures. The treatment intent was palliative, focusing on symptom control with systemic chemotherapy and whole brain radiotherapy.

Abstract
Since the introduction of Modernising Medical Careers in 2005, the electronic portfolio (ePortfolio) and workplace based assessments (WPBAs) have become integral, yet anecdotally controversial, components of postgraduate medical training. In this multi-centre, survey-based study, we looked at core medical trainees and trainers in the Northwest London region and their opinions of the ePortfolio and WPBAs. Our results demonstrate mixed feelings regarding these tools, with 60% of trainees stating that their training had not benefited from the use of an ePortfolio. 53% of trainers felt that feedback sessions with their trainees were useful; however 70% of them cited difficulties in fitting the required number of assessments within their clinical schedule. Overall, if implemented correctly, the ePortfolio and WPBAs are potentially powerful tools in the education and development of trainee doctors. However, improvements in mentoring and feedback may be needed to experience the full benefits of this system.

Abstract
Myotonic dystrophy (MD) is an autosomal dominant disorder which affects both smooth and skeletal muscles. The incidence is approximately 1 in 8,000 births. It is the most common muscular dystrophy to manifest in adulthood, and the second most common skeletal muscle disorder after Duchenne MD. Cardiac rhythm disturbances are a common cause of death in these patients. This lesson describes a case in which a previously undiagnosed case of MD presented with an episode of ventricular fibrillation.

Abstract
Reports of malignant melanoma involving the heart usually describe metastatic spread of pigmented (melanotic) forms of this tumour. We describe, and illustrate, a patient presenting with features related to cardiac tamponade and intracardiac obstruction. Transthoracic echocardiography initially showed a large mass within the right ventricular outflow tract. The full extent of infiltration of this tumour was demonstrated by computed tomography scanning and the specific tumour type by immunohistochemical staining procedures. The case is unusual in relation to the extreme size of this amelanotic melanoma at presentation and the fact that it appears to be a solitary metastasis.

Abstract
AL (amyloid light-chain) amyloidosis is an uncommon plasma cell disorder in which depositions of amyloid light-chain protein cause progressive organ failure and death in a median of 13 months. Autologous stem-cell transplantation is effective therapy for multiple myeloma and therefore, we evaluated its efficacy for AL amyloidosis. Patients with adequate cardiac, pulmonary, and renal function had stem cells mobilized with granulocyte-colony stimulating factor and were treated with dose-intensive intravenous melphalan (200 mg/m2). Response to therapy was determined by survival and improvement of performance status, complete response or persistence of the clonal plasma cell disorder, and change in the function of organs involved with amyloid at baseline. We enrolled 25 patients with a median age of 48 years (range, 29-60), all of whom had biopsy-proven amyloidosis with clonal plasma cell disorders. Twenty-two (88%) were Southwest Oncology Group performance status 1 or 2 within a year of diagnosis, and 16 (64%) had received no prior therapy. Predominant amyloid-related organ involvement was cardiac (n = 8), renal (n = 7), hepatic (n = 6), neuropathic (n = 3), and lymphatic (n = 1). Fifteen patients had one or two organ systems involved, whereas 10 had three or more involved. With a median follow-up of 24 months (12-38), 17 of 25 patients (68%) are alive, and the median survival has not been reached. Thirteen of 21 patients (62%) evaluated 3 months posttransplant had complete responses of their clonal plasma cell disorders. Currently, two thirds of the surviving patients (11 of 17) have experienced improvements of amyloid-related organ involvement in all systems, whereas 4 of 17 have stable disease. The improvement in the median performance status of the 17 survivors at follow-up (0 [range, 0-3]) is statistically significant versus baseline (2 [range, 1-3]; P < . 01). Significant negative prognostic factors with respect to overall survival include amyloid involvement of more than two major organ systems and predominant cardiac involvement. Three patients have experienced relapses of the clonal plasma cell disorder at 12 and 24 months. Dose-intensive therapy should currently be considered as the preferred therapy for patients with AL amyloidosis who meet functional criteria for autologous transplantation.

Abstract
The morbidity and lethality of AL amyloidosis is caused by the deposition of lg light chains as fibrillar amyloid protein in vital organs, disrupting their function, and not by the generally low burden of clonal plasma cells that produce the paraproteins. Survival of patients with AL amyloidosis is no more than 1 to 2 years from the time of diagnosis with current management approaches. Clearly, more effective therapies are needed for this rapidly lethal disease. Five patients were treated with dose-intensive melphalan and blood stem cell support and followed for a period of 1 year. Patients were diagnosed with AL amyloidosis by tissue biopsy and categorized by performance status and organ involvement. Their plasma cell dyscrasias were evaluated with immunofixation electrophoresis of serum and urine specimens, quantitative serum lgs, and immunohistochemical staining of bone marrow biopsy specimens. After treatment with dose-intensive intravenous melphalan followed by infusion of autologous growth-factor-mobilized blood stem cells, clinical evaluations and plasma cell studies were repeated at 3 and 12 months. Three men and 2 women aged 38 to 53 years were treated. Median performance status (SWOG) was 2 (1 to 3), and clinical presentations included nephrotic syndrome (n = 1), symptomatic cardiomyopathy (n = 1), gastrointestinal involvement with polyneuropathy (n = 2), and hepatomegaly (n = 1). With a median follow-up of 13 months (12 to 17 months), all five patients are well and have shown stable or improved performance status and clinical remission of organ-related dysfunction, including a 50% reduction in daily proteinuria with no change in creatinine, reversal of symptoms of cardiomyopathy and reductions of posterior wall and septal thickening, reversal of polyneuropathy and gastric atony, and resolution of hepatomegaly by computed tomographic scan. In 3 of the 5 patients (60%) at 12 months after treatment, plasma cell dyscrasias could not be detected. Dose-intensive chemotherapy with intravenous melphalan and growth-factor-mobilized blood stem cell support is feasible therapy for patients with AL amyloidosis, even when there is clinical evidence of cardiac involvement. At least some patients with AL amyloidosis achieve complete remission of their plasma cell dyscrasia, improvement in performance status, and clinical remission of organ-specific disease after this form of treatment.

Abstract
BACKGROUND Patients with AL amyloidosis and congestive heart failure have a very poor prognosis. To date, the recovery of these patients has not been described in detail. OBJECTIVE To determine the frequency and characteristics regression of disease in patients with congestive heart failure due to AL amyloidosis. DESIGN Review of patients with systemic AL amyloidosis. SETTING An international referral center for amyloidosis in the United States. PATIENTS 140 patients with congestive heart failure due to Al amyloidosis who were seen between 1983 and 1994. MEASUREMENTS Functional status, Doppler echocardiography, and objective measurements of disease activity. RESULTS 3 of 140 patients (2.1%) had marked resolution of congestive heart failure and evidence for remission of disease activity. All 3 had been treated with melphalan. CONCLUSIONS Melphalan appears to have had a favorable effect in 3 patients with AL amyloidosis and heart failure. The abolition of light chains that was seen in these 3 patients suggests that light-chain toxicity may play a role in the genesis of heart failure in patients with AL amyloidosis.
