Delayed Repair Of Aortic Dissection In Sickle Cell Anaemia As A Combined Cardiac And Vascular Surgical Approach, Massimo Capoccia, Maziar Mireskandari, Nicholas J. Cheshire, Ulrich P. Rosendahl

Journal of the Saudi Heart Association

We discuss a patient who presented with a type B aortic dissection with a retrograde progression in the context of sickle cell anaemia. Given the involvement of the superior mesenteric artery and concern for bowel ischaemia, a delayed approach was considered. Subsequently, a frozen elephant trunk was performed in the hybrid theatre with the back-up of the vascular surgeon for mesenteric protection. A technically demanding procedure followed by a prolonged and challenging postoperative course finally led to a successful outcome. We argue that the case presented is an example of how a close cooperation between professionals can offer additional options …

Journal of the Saudi Heart Association

Papillary Fibroelastomas are rare, primary cardiac tumors. They are typically diagnosed as an incidental finding but can also present as thrombo-embolic events. We present the case of 78-years- old man who presented to emergency room with a cerebrovascular event (CVE). Transesophageal echocardiography (TEE) revealed e presence of a mass on the aortic valve. Intra-operatively, two masses where found: one was highly mobile attached to left ventricular (LV) side of the left coronary cusp, another small size mass attached to the non-coronary cusp, and there was suspicion of a mass attached to the mitral valve. The two masses were surgically excised …

Myocardial Infarction Caused By An Enclosed Thrombus In A Patent Foramen Ovale, Meriem Boumaaz, Iliyasse Asfalou, Amine Hamami, Maha Raissouni, Zouhair Lakhal, Aatif Benyass

Journal of the Saudi Heart Association

Paradoxical embolism in coronary artery is a rarely diagnosed clinical entity. In the majority of reported cases; the diagnostic of this pathology is « presumptive » based on certain criteria. It can be considered “proven” when the embolus is found lodged in the abnormal communication between the venous and arterial circulation; which is very rare. We herein report a case of myocardial infarction caused by a proven paradoxical coronary embolism through a patent foramen ovale. The authors highlight through this paper the contribution of echocardiography and particularly transesophageal echocardiography, especially if performed soon after presentation, for early diagnosis.

Journal of the Saudi Heart Association

Intravenous drug use (IDU) poses a high risk of serious complications such as infective endocarditis (IE), which carries high morbidity and mortality rates. Mycotic pulmonary artery aneurysms (MPAA) are rarely associated with right-sided IE, especially in the setting of IDU. It is a potentially fatal complication as it can lead to severe hemorrhage if the aneurysm ruptures. We report the case of a young male with a history of current IDU and tricuspid valve replacement post complicated IE 2 years ago. The patient initially presented with massive hemoptysis and fever. Chest computed tomography (CT) showed a lobulated lesion in the …
