<Learning objective: Severe dengue including dengue shock syndrome is a potentially life-threatening condition. Dengue virus-induced coagulopathy and thrombocytopenia may further complicate cardiological interventions like percutaneous transluminal coronary angioplasty or coronary artery bypass grafting as such patients are already on antiplatelet drugs. Performing any cardiovascular intervention in an endemic area of dengue needs proper vigilance to avoid such potentially life-threatening complications.>
