Diffuse Coronary Artery Fistula Leading to Syncope and Treated with Transcatheter Coil Occlusion and a Defibrillator: A Case Report

Objectives: Coronary artery fistulas connecting coronary arteries to cardiac cavities are rare but clinically significant anomalies. Clinical Presentation and Intervention: A 47-year-old male patient presented with syncope. Left ventricular dysfunction was detected on echocardiography. Extensive coronary fistulas draining into the left ventricle were found on coronary angiography. Ventricular fibrillation was induced on electrophysiology study. Because of the induction of ventricular fibrillation, extensive fistulas, and presence of other risk factors, an implantable cardioverter defibrillator was implanted. After the detection of ischemia by nuclear scanning, microcoil occlusion of the fistula was performed. Conclusion: The present case describes extensive fistulas complicated with fatal ventricular arrhythmias due to ischemia and left ventricle dysfunction. A cardioverter defibrillator was implanted to prevent sudden cardiac death.

DIAGNOSIS DAN TATALAKSANA HEPATOPULMONARY SYNDROME

AbstrakSirosis hepatis dan penyakit hati kronik merupakan penyebab kematian terbanyak di seluruh dunia. Tingginya angka morbiditas dan mortalitas sirosis berhubungan dengan komplikasinya yang bersifat sistemik. Salah satu komplikasi sirosis dapat mengenai paru berupa sindrom hepatopulmonar atau hepatopulmonary syndrome. Hepatopulmonary syndrome (HPS) didefinisikan sebagai trias yang terdiri dari kegagalan hati stadium lanjut, hipoksemia arterial serta dilatasi intravaskular pulmonar tanpa disertai penyakit kardiopulmonar. Patogenesis HPS masih belum diketahui pasti, namun diduga terjadi gangguan metabolisme zat vasoaktif paru yang menimbulkan vasodilatasi vaskuler paru. Manifestasi klinis HPS berupa dispneu yang khas dengan tanda kegagalan hati dan hipertensi portal. Modalitas diagnostik HPS adalah radiologi thorax, analisa gas darah, contrast enhanced echocardiography (CEE), nuclear scanning dengan Tc-99m dan angiografi paru. Penatalaksanaan HPS terutama bertujuan menurunkan vasodilatasi intrapulmonar, meningkatkan oksigenasi arterial dan mengurangi keluhan. Deteksi dini terhadap komplikasi sirosis mutlak diperlukan dalam mencegah dan mengurangi angka morbiditas dan mortalitas.Abstract Liver cirrhosis and chronic liver disease are the leading cause of death worldwide. The high morbidity and mortality associated with their systemic complications. One of the complications of cirrhosis is hepatopulmonary syndrome. Hepatopulmonary syndrome (HPS) is defined as the triad of advanced-stage liver failure, arterial hypoxemia and pulmonary intravascular dilatation without cardiopulmonary disease. The pathogenesis of HPS is still not known for sure, but suspected metabolic disorder pulmonary vasoactive substances that cause pulmonary vascular vasodilatation. The clinical manifestations of HPS is typical dispneu with signs of liver failure and portal hypertension. HPS diagnostic modalities are radiology thorax, blood gas analysis, contrast enhanced echocardiography (CEE), nuclear scanning with Tc-99m and pulmonary angiography. HPS management aims primarily to lower intrapulmonar vasodilation, improving arterial oxygenation and reduce complaints. Early detection of complications of cirrhosis is absolutely necessary in preventing and reducing morbidity and mortality.

Osteomyelitis

•Clinical: Localized pain and tenderness of involved bone; systemic signs and symptoms of acute hematogenous osteomyelitis•Radiology: Bone destruction or sequestrum in chronic cases; use of nuclear scanning, magnetic resonance imaging, or computed tomography may aid diagnosis and staging•Laboratory: White blood cell count is often normal; erythrocyte sedimentation rate and C-reactive protein are usually elevated...

Aspiration in the Context of Upper Gastrointestinal Endoscopy

BACKGROUND: Pulmonary aspiration is a life-threatening complication of upper gastrointestinal endoscopy, the incidence of which has not been determined. Endoscopy-related aspiration has not been studied in procedures in which patients swallow a radiolabelled potential aspirate immediately before endoscopy and undergo nuclear scanning postprocedure.METHODS: A pilot study was conducted in which 200 MBq of non-absorbable technetium-99m phytate in 10 mL of water was administered orally to 50 patients who were about to undergo endoscopy. Gamma camera images were obtained to ensure that there had been no aspiration before endoscopy. After endoscopy, a repeat scan was performed. Fluid aspirated through the endoscope was also collected and analyzed for radioactivity using a hand-held radiation monitor.RESULTS: No evidence of pulmonary aspiration was found in any of the patients studied. The mean estimated percentage of the initially administered radioactivity aspirated through the endoscope was 2.66% (range 0% to 10.3%).CONCLUSION: The present pilot study confirms earlier observations that clinically significant aspiration in the context of upper gastrointestinal endoscopy is uncommon. The incidence of aspiration may, however, be different in acutely bleeding patients undergoing endoscopy. For logistic reasons, this group could not be studied.
