An 86-year-old man was admitted our hospital because of sudden onset of dyspnea after blunt chest trauma. Because his oxygen saturation deteriorated from 92% in the supine position to 86% in the sitting position, platypnea-orthodeoxia syndrome was suspected. Transesophageal echocardiography showed severe tricuspid regurgitation (TR) caused by anterior papillary muscle rupture. Read More

Background: Non-vitamin K antagonist oral anticoagulants (NOACs) require renal dose adjustment. The most common estimates of renal function in clinical practice are derived from estimated glomerular filtration rate (eGFR; Modified Diet in Renal Disease [MDRD] or the Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]). However, the landmark stroke prevention trials and product monographs recommend the use of the Cockcroft-Gault creatinine clearance equation (eCrCl) for drug eligibility and dose adjustment.

Background: Immune checkpoint inhibitors, including programmed cell death-1, programmed cell death ligand-1 and cytotoxic lymphocyte antigen-4 inhibitors, have emerged as important therapeutic alternatives for advanced malignancies. This drug class upregulates T-cell activity, leading to an immune response against cancer cells. However, the increased activity of T cells can lead to autoimmune reactions. Read More

A 58-year-old man with previous mitral/aortic mechanical-valve replacement, aortic root repair, and coronary disease developed severe left-ventricular dysfunction following AV-node ablation/single-chamber pacemaker implantation for management of atrial fibrillation. He then underwent an upgrade to cardiac resynchronization therapy with a defibrillator. To manage his heart failure better, angiotensin-receptor blocker therapy was changed to sacubitril/valsartan, after which symptomatic palpitations with T-wave oversensing occurred. Read More

A recent study found that rates of hospitalization for syncope vary across provinces; however, it is unknown whether differences in comorbidity burden and outcomes also exist. The Canadian Institute for Health Information Discharge Abstract Database was used to identify primary syncope hospitalizations (ICD-10 code R55) from 2004 to 2013 for all provinces (except Quebec). Charlson comorbidity score was calculated from comorbidities at the time of hospitalization. Read More

For older people, and in particular frail older people, acute illness and hospitalization are associated with significant potential harm. One of the major drivers of iatrogenic harm in older adults is hospital-induced immobility, the so-called "pajama paralysis." Older people in hospital are often confined to bed even after their acute illness has improved; not only by physical factors such as potentially unnecessary urinary catheters and monitoring equipment but also by the culture often found in hospital of keeping patients in bed for most of the day.

With advances in health care practices and delivery, the overall life expectancy of the Western population has increased. For those practitioners involved in the care of the patient with advanced cardiac disease, there has been a resultant higher prevalence of increasingly frail and older patients undergoing complex cardiac procedures. The higher rates of comorbid-associated higher vulnerability, with associated deconditioning, predisposes older, frail patients to poorer postoperative outcomes and a complicated recovery process after cardiac surgery.

Patients resuscitated from out-of-hospital cardiac arrest (OHCA) frequently have underlying coronary artery disease (CAD), but the relationship between the arrest and myocardial ischemia or infarction due to CAD can be difficult to discern in clinical practice. Patients often present with clinical profiles that guideline recommendations for appropriate implantable cardioverter-defibrillator use do not address. In cases of incomplete revascularization or mild but sustained impairment of ventricular function, it is not clear if the cause of the cardiac arrest is completely "reversible. Read More

Cardiovascular disease (CVD) is a leading global cause of death and morbidity and prevention needs to be strengthened to tackle this. Mobile health (mHealth) might present a novel and effective solution in CVD prevention, and interest in mHealth has grown dramatically since the advent of the smartphone. In this review, we discuss mHealth interventions that target multiple cardiovascular risk factors simultaneously in the context of primary as well as secondary prevention. Read More

Background: The dilated cardiomyopathy with ataxia syndrome (DCMA) is a rare mitochondrial disorder characterized by progressive cardiomyopathy, prolonged QT interval and early death in childhood related to intractable heart failure. We present a case series of 9 children with DCMA who demonstrated functional improvement and favourable left ventricular remodeling only after digoxin was added to their medical therapy.
Methods: A retrospective review of 46 patients with DCMA followed at the Alberta Children's Hospital from 2005 to 2017 identified 9 patients who were treated with digoxin and had serial echocardiography data. Read More

Delivering evidence-based, personalized care that engages patients requires profound changes in the structure, process, and organization of care, along with revised incentives to support such changes. Health care providers must absorb and apply a vast, usually overwhelming, amount of scientific information to provide high-quality patient care. Accordingly, care remains inconsistent, with unintentional adverse consequences. Read More

Heart failure represents a significant burden for patients and the Canadian health care system. Home telemonitoring is proposed as an intervention that can improve heart failure outcomes by identifying opportunities for earlier clinical intervention and by providing patients with self-management support between scheduled clinic visits. The objective of this review is to provide clarity with respect to the most recent evidence of the effect of home telemonitoring on heart failure outcomes. Read More

The coexistence of idiopathic pulmonary artery hypertension with pulmonary arteriovenous malformation (PAVM) is challenging because although the PAVM causes hypoxia and polycythemia with potential thrombotic complications, closing the PAVM increases pulmonary artery pressure. We report on a lady with PAVM and idiopathic pulmonary artery hypertension who, within 2 years of diagnosis, had an ischemic stroke, PAVM enlargement from 20 × 20 × 30 mm to 30x × 40 × 40 mm and oximetry decrease to 90%. Transcatheter occlusion of PAVM with a vascular plug was successful. Read More

We present the case of a 4-month-old child with atrioventricular canal associated with severe left atrioventricular valve dysfunction who previously underwent 3 surgical valve reconstructions without significant improvement. A Hybrid Melody valve (Medtronic, Minneapolis, MN) insertion was planned. Because of the low weight, the risk of left ventricular outflow tract obstruction was significant and therefore evaluated preprocedurally using a cardiac computed tomography-derived 3-dimensional printed model.

Background: Novel quantification of stroke volume according to mitral inflow and aortic outflow using automated real-time 3-dimensional volume colour flow Doppler echocardiography (3D-RT-VCFDE) is more accurate than 2-dimensional echocardiography and has excellent correlation with cardiac magnetic resonance imaging-based flows in adults. This technology is applied for the first time to the right heart and in children.
