Abstract

A 65-year-old man with severe coronary artery disease and coronary artery bypass graft presented with an acute posterior ST-elevation myocardial infarction. Immediate percutaneous coronary intervention resulted in successful revascularisation of the culprit lesion (RCx) with several remaining coronary stenoses. Despite the reduced left ventricular ejection fraction, no primary prevention indication for an implantable cardioverter/defibrillator early after myocardial infarction existed. Due to the complex coronary anatomy with several remaining stenotic vessels we regarded the patient to be at a particularly high risk for lethal ventricular arrhythmias and provided him with a wearable cardioverter defibrillator (WCD). Twenty-six days later, he experienced spontaneous ventricular tachycardia and fibrillation which was successfully treated with high voltage therapy by the WCD. Subsequently, we decided to implant him an ICD following secondary prevention indication. Besides established indications for primary prevention ICD therapy, some patients early after myocardial infarction may be at a particularly high risk for sudden cardiac death. Temporary protection with a WCD in carefully selected patients can offer a safe opportunity f...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
