Transcatheter Aortic Valve Implantation in a Patient With Anomalous Left Main Coronary Artery from Right Coronary Artery.

Transcatheter aortic valve implantation (TAVI) is now a well-established modality of treating severe symptomatic aortic valve stenosis in patients deemed at great surgical risk. In patients with coexisting anomalous coronary arteries, however, TAVI presents technical challenges, and coronary obstruction is a feared complication. In this study, we present the case of successful TAVI in a 78-year-old patient with anomalous left main coronary artery originating from the right coronary artery.

Impact of improving severity of secondary mitral regurgitation on survival.

Aims: Secondary mitral regurgitation (SMR) is frequent in patients with heart failure with reduced ejection fraction (HFrEF) and portends detrimental prognosis. Despite interventions addressing the mitral valve (MV) have been proven effective to improve survival, an important knowledge gap exists regarding the role of medical therapy (MT) in this context. Thus, we aimed at investigating the role of MT optimization in patients with SMR and HFrEF.

Severe Mitral Paravalvular Leak Treated with Percutaneous Paravalvular Leak Closure with Underlying Severe Mitral Annular Calcium.

Standard operative mitral valve replacement for mitral stenosis in the setting of severe mitral annular calcium has been associated with increased morbidity and mortality. Inability to ensure a well seated prosthesis may lead to periprosthetic leak. We present a case of severe paravalvular leak, causing significant hemolysis, after mitral valve replacement with underling severe mitral annular calcium.

Coronary Chronic Total Occlusion Antegrade Wire Technique to Successfully Cross a Common Iliac Chronic Total Occlusion from Retrograde Access.

Percutaneous endovascular intervention is the preferred modality of revascularization for iliac arterial obstructive disease. Chronic total occlusions (CTO) of the iliac arteries can be uniquely challenging, as typically utilized polymer jacketed 0.035 in wires have a tendency to enter subintimal planes within the iliac artery or aorta, which consequently require complicated re-entry wire techniques.

Enterovirus-associated hemophagocytic lymphohistiocytosis with multiorgan failure.

Hemophagocytic lymphohistiocytosis is a highly fatal hyperinflammatory syndrome that is increasingly being recognized in adults. It can be primary or secondary in the setting of malignancy, autoimmune disorders, infections, or acquired immune deficiencies. We present a case of a 50-year-old man with enterovirus-associated multiorgan system dysfunction and hemophagocytic lymphohistiocytosis.

The ketogenic diet and the QT interval.

Long QT syndrome is a disorder of ventricular myocardial repolarization associated with an increased risk of life-threatening cardiac arrhythmias and sudden cardiac death. This report highlights a case of QT prolongation with torsades de pointes in a patient with baseline congenital long QT syndrome, believed to be precipitated by metabolic changes associated with the "ketogenic diet."

Alteration of lipid metabolism in chronic kidney disease, the role of novel antihyperlipidemic agents, and future directions.

The role of anti-hyperlipidemic therapy remains of key importance in the treatment of atherosclerotic disease. Moreover, given an already exaggerated predisposition for vascular disease at baseline, there is a preponderance of data that show management of hyperlipidemia is especially important in patients with chronic kidney disease. This is a concise, up-to-date review of lipid physiology, alterations in lipid concentrations with progressive renal failure, and currently available and emerging hyperlipidemic treatment options.

Delayed complication of abdominal aortic stent: a rare complication.

We hereby present a case of recurrent abdominal aortic aneurysm due to endoleak to outline complications and secondary intervention strategies post endovascular aneurysm repair.

Guidelines for Perioperative Management of the Diabetic Patient.

Management of glycemic levels in the perioperative setting is critical, especially in diabetic patients. The effects of surgical stress and anesthesia have unique effects on blood glucose levels, which should be taken into consideration to maintain optimum glycemic control. Each stage of surgery presents unique challenges in keeping glucose levels within target range.

Comorbidity of diabetes and obstructive sleep apnea in hospitalized patients.

Obstructive sleep apnea (OSA) and type 2 diabetes are two morbidities commonly encountered in the hospitalized setting. Both diseases will present with an array of complications if not managed in a timely, competent manner. However, a growing body of evidence suggests a link between these two pathologies.

Delayed recurrence of atypical pulmonary carcinoid cluster: a rare occurrence.

Carcinoid is one of the most common tumors of the gastrointestinal tract followed by the tracheobronchial tree. Bronchial carcinoid compromises 20% of total carcinoid and accounts for 1-5% of pulmonary malignancies. Carcinoid can be typical or atypical, with atypical carcinoid compromises 10% of the carcinoid tumors.

Prolonged ventricular asystole: a rare adverse effect of hydrocodone use.

Background: Prolonged ventricular asystole is a rare vagal reaction caused by hydrocodone use. Sinus bradycardia is a characteristic presentation of the vasovagal response; examples of other presentations include arrest or atrioventricular block. Physicians need to be aware of ventricular asystole due to vagally-mediated atrioventricular block caused by hydrocodone or other opiates.

Spontaneous extraperitoneal lumbar artery hemorrhage.

Background: Spontaneous extraperitoneal hemorrhage (SEH) is an uncommon complication of anticoagulation therapy. Cases of SEH that are unresponsive to management through correction of coagulopathy, fluid resuscitation, blood transfusion, and other supportive measures are typically treated with surgery. Nevertheless, treatment of SEH with the use of angiography and arterial embolization may provide a safe, efficacious alternative to surgery.
