Personalized allocation of acetylsalicylic acid therapy for secondary prevention of coronary artery disease.

Background: A single-daily dose of 75 mg of acetylsalicylic acid inhibits 100% of thromboxane-B2 synthesis within 30-60 min. Thromboxane-B2 synthesis then recovers slowly as new platelets are released from the bone marrow. Normally, only 10% of the platelets are replaced daily by new platelets entering circulation.

Thrombus-in-transit involving all four chambers of the heart in a patient presenting with acute pulmonary embolism.

Unlabelled: A 43-year-old male with history of pulmonary embolism defaulted on anti-coagulation and presented with recurrent massive pulmonary embolism. Echocardiography revealed a serpiginous freely floating right atrial thrombus prolapsing through the tricuspid valve into the right ventricle. Thrombus was also seen crossing the interatrial septum into the left atrium and prolapsing into the left ventricle.

A Case of Delayed Non-infective Cystic Swelling at the Pacemaker Pocket Site.

With the expanding indications for device implantation, the number of cardiac implantable electrophysiological devices (CIED) being implanted has increased drastically. In a patient presenting with swelling at the pacemaker pocket site several years after the implantation, an infective collection due to device seeding by blood-borne microorganisms is the first diagnosis that is commonly considered. Once the diagnosis of CIED infection is made, complete removal of all the hardware is usually performed.

An adult patient with previously undiagnosed sinus venosus atrial septal defect presenting with brain abscess: a case report.

Background: Brain abscess is a common complication in children with cyanotic congenital heart disease. The presence of an underlying acyanotic congenital heart disease is usually not suspected in an adult patient presenting with brain abscess.

Case Summary: A 51-year-old male patient with no known co-morbidities came with complaints of recent onset right lower limb weakness needing support while walking and on evaluation was found to have brain abscess.

Troubleshooting a pacemaker output failure: A case report.

The indications for permanent pacemaker (PM) implantation are rapidly expanding resulting in an increasing number of patients receiving PMs. Such PM patients need a good quality medical care. The follow up of these patients and their devices places a heavy burden on cardiology clinics with significant implications for the already stretched hospital resources.
