Thalassemia is the most common monogenetic disorder worldwide, with 60 000 infants with thalassemia major born annually.1 Survival often depends on regular blood transfusions to correct anemia and to reduce ineffective erythropoiesis, but these transfusions can result in iron overload and organ failure unless chelation therapy is undertaken. Serum ferritin levels continue to be used as a guide to chelation but are unreliable, and the availability of cardiovascular magnetic resonance (CMR) T2* imaging has transformed patient management by allowing organ-specific quantification of iron content.2,3

Electrocardiographic feature is included in the diagnostic criteria for arrthythmogenic right ventricular dysplasia (ARVD) based on the Revised Task Force criteria 2010. The epsilon wave, which reflects delayed conduction of the right ventricle, is considered to be one of the major diagnostic criteria. We reported a 13‐year‐old Thai boy with ARVD who presented with ventricular tachycardia. The presence of epsilon wave in all precordial leads (V1–V6) was observed in standard 12‐lead EKG. Extensive scarring of the right and left ventricle was seen on cardiac MRI. The extensive Epsilon wave found in this patient may reflect the extensive ventricular wall involvemen.

Pyopneumopericardium and empyema thoracis from perforated oesophageal cancer

Nitinan Chimparlee; Monravee Tumkosit; Kittichai Luengtaviboon; Pairoj Chattranukulchai

A 79-year-old Thai man with a history of untreated mid-oesophageal cancer presented with progressive dyspnoea and productive cough for 3 weeks. On examination, he had low-grade fever, tachyponea, regular pulse rate at 110/min, blood pressure 120/78 mm Hg without definite pulsus paradoxus. Pulmonary examination showed mild deviation of trachea to the right, dullness on percussion and decreased breath sound at the left lung. He also had mildly distended neck veins, decreased cardiac sound and decreased apical impulse. ECG revealed sinus tachycardia with low QRS voltage without significant ST-T change. A large amount of generalised high-echoic pericardial fluid and evidences of early cardiac temponade were demonstrated by transthoracic echocardiography. Contrast-enhanced CT of the chest showed known circumferential oesophageal mass at the middle …

Effect of Sodium Thiosulfate on Arterial Stiffness in End-Stage Renal Disease Patients Undergoing Chronic Hemodialysis (Sodium Thiosulfate-Hemodialysis Study): A Randomized Controlled Trial

Background: Arterial stiffness (AS) and vascular calcification are significantly related to a high cardiovascular mortality risk in hemodialysis (HD) patients. Intravenous sodium thiosulfate (IV STS) can prevent and delay the vascular calcification progression in uremic states; however, the STS effect on AS has not been assessed. This study aimed to evaluate the STS efficacy on vascular calcification and AS in HD patients. Methods: Fifty HD patients with abnormal AS, as measured via the cardio-ankle vascular index (CAVI ≥8), were prospectively randomized to open-label 12.5 g IV STS during the last HD hour twice weekly for 6 months (n = 24) or the usual care (control group; n = 26). Patients and treating physicians were not blinded. The CAVI, coronary artery calcification (CAC) score, hemodynamics, and biochemical parameters were measured at the baseline and at 3 and 6 months. Results: All the baseline parameters were comparable. The IV STS significantly reduced the CAVI when compared to the control group (mean CAVI difference = –0.53; 95% CI –1.00 to –0.06; p = 0.03). A significant CAVI improvement was seen in those patients without diabetes mellitus. The natural logarithm of the CAC volume score was significantly increased in the control group. The high sensitivity C-reactive protein level was slightly lowered in the IV STS group (not significant). Conclusion: The intradialytic STS treatment significantly reduced the AS, as measured by the CAVI, and stabilized the vascular calcification in the HD patients. STS may be a novel therapeutic strategy for delaying and treating the structural and functional vascular wall abnormalities in HD patients.

Very late presentation of anomalous origin of the left coronary artery from the pulmonary artery: case report

BackgroundAnomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle. We present the oldest reported patient with ALCAPA to undergo corrective surgery.Case presentationA 79-year-old woman presented with a 3-months history of worsening shortness of breath and orthopnea. Physical examination discovered a soft continuous murmur at the left upper chest. Transthoracic echocardiography demonstrated an unusual, tubular-like structure inside the interventricular septum with a turbulent flow from color Doppler. Moreover, there was a severe mitral regurgitation from posterior mitral leaflet restriction associated with ventricular remodeling in combination with mitral annular dilatation. Coronary angiography and coronary computed tomography angiography established the diagnostic hallmark of ALCAPA syndrome. Stress cardiovascular magnetic resonance perfusion imaging demonstrated no myocardial ischemia suggesting adequate collateral circulation. Remarkably, there was a left coronary ostial stenosis, which served as a protective mechanism against myocardia ischemia by limiting the steal effect. The patient successfully underwent the ligation of anomalous artery at its origin in combination with bioprosthetic mitral valve replacement. Her postoperative course was uneventful.ConclusionsThis case utilized multimodality imaging for delineating the course of abnormal vessels and helping to formulate therapeutic decision.

Calcium sign of thoracic aortic dissection in Takayasu’s arteritis

Vorarit Lertsuwunseri; Pairoj Chattranukulchai; Monravee Tumkosit; Smonporn Boonyaratavej

A 53-year-old woman with known chronic atrial fibrillation was referred for evaluation of abnormal chest film. She has been diagnosed with Takayasu’s arteritis 10 years earlier when she underwent right subclavian-to-common carotid artery bypass grafting due to major aortic branches occlusion. Initial examination revealed totally irregular pulse with cardiomegaly. The blood pressure was normotensive without significant difference among all extremities. Chest film unveiled cardiomegaly with long, diffuse calcified descending thoracic aorta (figure 1A, arrowheads). Notably, dilatation of the proximal descending thoracic aorta was suggestive …
