Transcatheter aortic valve implantation for severe aortic stenosis

A Garg, S Verna

CMAJ 2019, vol 191 (5): E134

1 – Transcatheter aortic valve implantation is first-line therapy for high-risk patients with severe symptomatic aortic stenosis

2 – The procedure should be performed at a dedicated centre of excellence specializing in treatment of valvular heart disease

3 – There are unique postoperative risk associated with transcatheter aortic valve implantation

4- While thromboprophylaxis is recommended after transcatheter replacement, the choice of therapy is controversial

5 – Routine endocarditis prophylaxis is recommended for patients with na implanted transcatheter aortic valve

CMAJ 2019, vol 191 (32): E894

1 – Protein convertase subtilisin-kexin type 9 (PCSK9) inhibitors are a new class of low-density lipoprotein (LDL-c) lowering medications

The cardiovascular benefits of low-dosage acetylsalicylic acid

P Koipillai, N S Nishtala

CMAJ 2019, vol 191 (43): E1194

1 – Acetysalicylic acid (ASA) has established benefit in the secondary prevention of cardiovascular disease

2 – The benefit of ASA in the primary prevention of cardiovascular disease is offset by potential bleeding risks

3 – Patients with diabetes, despite their increased cardiovascular risk, have questionable benefit from ASA used for primary prevention

4 – Perioperative use of ASA in noncardiac surgery is unlikely to reduce the risk of myocardial infarction or venous thromboembolism

5 – Acetysalicylic acid should be used patients with myocardial injury or ischemia after noncardiac surgery

Direct oral anticoagulante and the bleeding patients

B Wood, M Sholberg, A Ackery

CMAJ 2016, vol 188 (3): 215

1 – Direct oral anticoagulante agentes are now routinely used for the prevention of stroke in nonvalvular atrial fibrillation

2 – Risk of bleeding with direct oral anticoagulantes is lower than with vitamin K antagonists, but varies by site

3 – Direct oral anticoagulants are characterized by rapid onset of action and short half-live

4 – Direct oral antiagulants variably affect standard clot-based assays

5 – Idarucizumab has recently been approved by the US Food and Drug Administraton to reverse the activity of dabigatran

4 – Pospartum hypertension may persist for several weeks

5 – Postpartum hypertension can be treated safely during breastfeeding

Screening for fetal congenital heart disease

A Pham, M Melchior

CMAJ 2017, vol 189 (12): E468

1 – Congenital heart disease is the most common caue of infant death and morbidity from birth defects

2 – Referral for fetal echocardiography should bem ade in cases where nuchal tanslucency is above the 99th percentile

3 – Most cases of congenital heart disease occur n low-risk populations

4 – Both maternal and fetal factors may prompt referral for fetal echocardiography

5 – Some lesions can be treated antenatally

Cardiopulmonary resuscitation

F Khan, C Vaillancourt

CMAJ 2017, vol 189 (1): E25

1 – Chest compressions during cardiopulmonar resuscitation should be fast pushes

2 – Perischock pauses should be limited to improve survival

3 Rescuers may adopt an interrrupted or continuous CPR strategy

4 – Vasopressin offers no advantage over epinephrine in cardiac arrest

5 – A target temperature should be maintained in the postcardiac arrest period

Alergia: Five Things to Know About Online (Allergy: Five Things to Know About)

Penicillin allergy

D J McCullagh and D K Chu

CMAJ 2019, vol 191 (8): E231

1 – Penicillin allergy is commonly reported, but 9 out of 10 times, penicillin will be tolerated if administered

2 – The label of penicillin allergy is bad for patients and the health care system

3 – Patients reporting penicillin allergy can be easily risk stratified to determine whether they require specialist evaluation

4 – Penicillin allergy is lost over time, with resolution in 80% of people over 10 years, and in 50% over 5 years

5 – Allergy referral and testing is vastly under used, but is safe, accurate, rapid and cost-effective

Vaccine alllergy

D K Chu, Z Abdurrahman

CMAJ 2019, vol 191 (14): E395

2 – The most common adverse events of vacines are fever, local pain or irritation, and local redness or swelling, whic are not signs of allergy

3 – Patients with egg allergy can be safely vaccinated with several vacines without any special

4 – Vaccine allergies are typically unpredictable specific to a single vaccine

5 – Even if patients are truly allergic to a vaccine, allergists can often safely vaccinate them

CMAJ 2018, vol 190 (17): E542

1 – Eosinophilic esophagitis is becoming more common

2 – Eosinophilic esophagitis should be suspected in patients presenting with dysphagia or food bolus obstruction

3 – Endoscopic findings alone are not suficiente to make a diagnosis of eosinophilic esophagitis

4 – Proton pump inhibitors should be prescribed for a histologic finding of esophageal esosinophilia

5 – Topical steroids and elimination diets are the mainstays of therapy
