The rarity of endocarditis due to Klebsiella species limits its recognition. We report the case of a 63-year-old man, known to have a tight calcified aortic stenosis presenting with acute heart failure associated with high fever. Klebsiella oxytoca endocarditis was diagnosed based on three sets of positive blood cultures together with fluttering vegetation (11 mm × 14 mm) on the middle segment of the anterior leaflet of the mitral valve. After 6 weeks of intravenous ceftriaxone and gentamicin bi-therapy, the patient had completely recovered. This case illustrates how sporadic this condition is, for which early assessment and proper treatment are crucial to enhance the short outcomes.

Hypertrophic cardiomyopathy (HCM) is a common inherited cardiomyopathy, with an estimated prevalence of 1 in 500 people. Despite overall favorable outcomes with modern treatment and early diagnosis of disease, adverse complications could occur during times of physiological stress like pregnancy. Complications of HCM include sudden cardiac death, heart failure, and arrhythmia. We report the case of a 32-year-old pregnant woman with obstructive HCM, presenting with recurrent episodes of ventricular arrhythmia despite medical therapy. This case exhibits how close monitoring and proper management during pregnancy according to the latest recommendations, resulted in a successful and uneventful delivery.

Hydatid disease is caused by the larvae of Echinococcus granulosus. Domestic animals like cats and dogs are the primary carriers of echinococcal organisms. This parasitosis is still endemic in some particular regions of the world. The cardiac hydatid cyst is an exceptional infection. We report a case of an asymptomatic giant cardiac hydatid cyst in the interventricular septum (IVS) protruding in the right ventricular diagnosed incidentally by scan tomography during acute pancreatitis emergency. Transthoracic echocardiography revealed a cystic mass in the IVS bulging into the right ventricle. The diagnosis was confirmed by a cardiac CT scan.

The innominate artery aneurysm (IAA) accounts for a small percentage of all peripheral aneurysms. However, its clinical outcomes are potentially devastating, especially when it is associated with coronary disease, due to the high risk of spontaneous rupture and thromboembolic complications. Surgical repair is always recommended in such cases. The treatment of such a condition presents a surgical challenge with high morbidity and mortality rates. In this report, we discuss the case of a 56-year-old male who presented with a right cervical mass secondary to a large IAA with underlying coronary artery disease. The patient underwent a simultaneous operation for IAA and coronary bypass grafting.
