We present a case of transcatheter valve-in-valve replacement performed because of structural valve deterioration of a subcoronary implanted stentless aortic bioprosthesis. A 23-mm self-expandable transcatheter heart valve (THV) with supraannular seating was chosen. The procedure was performed with the patient under conscious sedation. After anchoring and partial valve deployment, the patient experienced an acute onset of angina. The angiogram showed left main coronary artery obstruction. Prompt resheathing and retrieval of the THV was performed, and the procedure was aborted...

Spontaneous coronary artery dissection (SCAD) is an uncommon disease. We report the case of a 50 year-old woman with a past medical history of aneurysmal subarachnoid hemorrhage, presenting with acute chest pain and diffuse ST segment elevation on ECG. Coronary angiogram revealed a SCAD of the left anterior descending coronary artery. The association between cerebral aneurysms and SCAD should trigger providers concern for fibromuscular dysplasia. We hereby report on a rare and atypical case involving the relationship between fibromuscular dysplasia and SCAD...

Moyamoya syndrome is a rare cerebrovasculopathy of unknown etiology which is associated with multiple risk factors. Moyamoya was first discovered in Japan and is reported to have an increased prevalence in the Japanese population. The term "Moyamoya" translates into "puff of smoke" and is named after the finding of the collateral cerebral vasculature that develops secondary to occlusion of an internal carotid artery at the entrance into the circle of Willis. This collateral vasculature characterizes the disease...

BACKGROUND Nicorandil is a nicotinamide ester commonly prescribed for treatment of patients with coronary heart disease (CHD). In the present study, we aimed to explore the cardioprotective effects of nicorandil on CHD patients undergoing elective percutaneous coronary intervention (PCI). MATERIAL AND METHODS One hundred patients with CHD undergoing PCI were randomly divided into a control group (n=48) and a nicorandil group (n=52). Patients in the control group received traditional therapy, and while patients in the nicorandil group received nicorandil before PCI in addition to the traditional therapy...

We report the case of a 36-year old man who underwent elective posterior lumbar spinal fusion after presenting with bilateral leg pain with associated back pain. He had undergone a L5/S1 discectomy in 2001, which provided good symptomatic relief. On this admission, he underwent elective L4-S1 posterolateral fusion and bilateral L4/5 and L5/S1 decompression. Intra-operatively a pedicle screw had to be re-inserted after fluoroscopy confirmed a lateral breech. The patient had no major postoperative complications until the sixth day when the patient re-presented with acute leg pain and weakness...

Pericardial effusions arise as an extra-articular manifestation of rheumatoid arthritis (RA). Pericardial effusions are often asymptomatic, particularly in the early phase, but patients are at risk of cardiac tamponade as the effusion progresses. We discuss the case of a 40-year-old male ultramarathon runner with RA who presented with mild pleuritic chest pain and exertional dyspnoea after a recent long-haul flight. Despite a relative tachycardia, his observations were otherwise unremarkable. His blood tests revealed a C-reactive protein (CRP) of 86 mg/L and an anti-cyclic citrullinated peptide (anti-CCP) titre of 360 units/mL...

Arteriovenous fistulas can lead to a number of different chronic complications. We describe a case where a patient developed a thrombosis within her brachiobasilic arteriovenous fistula, which was manually manipulated in order to restore fistula flow. This resulted in a pulseless electrical activity cardiac arrest within a few minutes. After ten minutes of chest compressions and intubation, there was return of spontaneous circulation. No epinephrine was given nor shocks administered. Patient was extubated within minutes and was alert, orientated and haemodynamically stable...

A 78-year-old man was referred from his primary care clinic to the emergency department due to bluish discolouration of his lips and decreased oxygen saturation on pulse oximetry. The patient was asymptomatic. Physical exam was normal except for lip cyanosis. A CT pulmonary angiogram was negative for pulmonary embolism. Arterial blood gas (ABG) analysis with co-oximetry showed low oxyhaemoglobin, normal partial pressure of oxygen and methaemoglobinaemia, but an unexplained 'gap' in total haemoglobin saturation...

PURPOSE: Retinal arteriolar macroaneurysms are a common cause of vision loss in elderly patients with hypertension and cardiovascular disease. Their occurrence in the young, however, is not well known. The purpose of this article is to describe an unusual cause of retinal arteriolar macroaneurysm in a healthy young man. CASE REPORT: A 30-year-old man presented with preretinal hemorrhage and macular exudation due to ruptured retinal artery macroaneurysm. The patient was treated with intravitreal bevacizumab and laser photocoagulation to the macroaneurysm...

James Thomas Connell
Saphenovenous graft aneurysm is a rare complication of coronary artery bypass grafts that is likely underdiagnosed. It is typically asymptomatic, slow growing, and often diagnosed incidentally on angiography or following catastrophic rupture. There is no consensus on best management but PCI and surgery appear to have more favourable mortality outcomes relative to conservative management. We present the case of a 48-year-old male with a cardiovascular risk profile hallmarked by diabetes mellitus, end stage renal failure, recalcitrant hyperlipidaemia, and IHD previously treated with CABG...

BACKGROUND Air embolism into the systemic arterial circulation secondary to pulmonary barotrauma has rarely been reported. Herein, we report the clinical course of an extremely rare presentation of cerebral air embolism likely due to ruptured pulmonary bullae during commercial air travel. CASE REPORT A 65-year-old man suddenly became unconscious during an airplane descent. Upon landing, he was immediately transferred to the nearest emergency department where he was intubated for airway protection. His head CT angiogram showed multiple air pockets in the right parietal lobe suspicious for multiple air emboli...

REVIEW
Francesco Pelliccia, Juan Carlos Kaski, Filippo Crea, Paolo G Camici
Originally described by Japanese authors in the 1990s, Takotsubo syndrome (TTS) generally presents as an acute myocardial infarction characterized by severe left ventricular dysfunction. TTS, however, differs from an acute coronary syndrome because patients have generally a normal coronary angiogram and left ventricular dysfunction, which extends beyond the territory subtended by a single coronary artery and recovers within days or weeks. The prognosis was initially thought to be benign, but subsequent studies have demonstrated that both short-term mortality and long-term mortality are higher than previously recognized...

BACKGROUND: There are conflicting data between natural history studies suggesting a very low risk of rupture for small, unruptured intracranial aneurysms and retrospective studies that have identified a much higher frequency of small, ruptured aneurysms than expected. OBJECTIVE: To use the prospective International Study of Unruptured Intracranial Aneurysms cohort to identify morphological characteristics predictive of unruptured intracranial aneurysm rupture. METHODS: A case-control design was used to analyze morphological characteristics associated with aneurysm rupture in the International Study of Unruptured Intracranial Aneurysms database...
