Aortico left ventricular tunnel and bicuspid aortic valve with severe stenosis: a rare combination
Aortico left ventricular tunnel (ALVT) is a rare, abnormal paravalvular communication between the aorta and the left ventricle.1 After the first description by Edwards in 1961, approximately 130 cases have been reported in the literature. However, there are only a few reports of ALVT associated with severely stenotic bicuspid aortic valve.2 The aetiology of aortico-ventricular tunnel is unknown. The formation of the tract is considered as a consequence of primary separation of the aortic annulus from the fibrous skeleton of the heart. The failure of normal development of the tissue plane between the facing aortic and pulmo...

Effective ECG reference ranges for Northern Thai people
Conclusions
We observed that the general trend of data was mainly similar to that found in other studies in Chinese, American, and African populations. However, some minor differences should be considered specifically for the Northern Thai population. Flexible criteria on conditions depending on age and gender should be adjusted for Northern Thai patients according to the results of this research. (Source: Heart Asia)

Prevalence of congenital heart disease in patients undergoing surgery for major gastrointestinal malformations: an Indian study
Conclusions
We found the frequency of CHD in patients with GI malformations was very high, the most common presentation being ASD. Our study indicates the need for larger scale studies to determine the prevalence of CHD in patients with GI malformations in the Indian population. (Source: Heart Asia)

Left main coronary artery ostial occlusion in a young man: late sequelae of Kawasaki's disease?
A 26-year-old man was admitted with a history of New York Heart Association (NYHA) class II dyspnoea of 2 months’ duration. An electrocardiogram showed diffuse ST segment depression and ST segment elevation in aVR. Echocardiography showed anterior wall hypokinesia with moderate left ventricular dysfunction. Coronary angiography showed a normal right coronary artery (RCA) (figure 1A) and near total occlusion of the left main coronary artery ostium and collaterals filling the left main artery from the aortic sinus (figure 1B–D). The left system received heterocollaterals from the RCA. The entire aorta and br...

Poor adherence to anticoagulation guidelines in patients with non-valvular atrial fibrillation treated in a tertiary cardiology unit
Conclusions
Few patients who require anticoagulation receive it in accordance with the guidelines even in a tertiary cardiology unit. There are many impediments to the effective use of VKA for stroke prevention among patients with AF. (Source: Heart Asia)

H1N1-associated sinus node dysfunction
A 51-year-old previously healthy man presented to the emergency room following an episode of presyncope. He had a history of fever, pleuropericardial chest pain and dyspnoea accompanied by important myalgia evolving over several days. His past medical history was negative for any cardiovascular or pulmonary disease, and he was a lifelong non-smoker. He was previously very active with an excellent exertional capacity. His physical exam showed no frank heart failure, and he was haemodynamically stable. Laboratory results showed increased inflammatory markers including an erythrocyte sedimentation rate of 35 mm/h (normal...

Coronary intervention in diabetes: is it different
Introduction Diabetics are at an increased risk of cardiovascular morbidity and mortality as a consequence of inherent metabolic abnormalities and comorbidities. Furthermore, these patients derive less benefit from the standard therapies of coronary artery disease (CAD); the unique pathophysiological response to arterial injury has a profound effect on outcomes of percutaneous coronary interventions (PCIs). However, as the technology, techniques and experience of operators in PCI are evolving, the understanding of revascularisation strategies and patterns of clinical practice are changing. In this review, we discuss specif...

Central (garland) aortopulmonary shunt
A 24-year-old woman, with unoperated tetralogy of Fallot, presented with refractory cyanosis and was listed for emergency palliative shunt surgery. Preoperative cardiac catheterisation or CT angiography could not be performed. The size of the pulmonary artery (PA) appeared borderline on echocardiographic assessment. A central shunt, connecting the ascending aorta to the main PA, was created using a 6 mm polytetrafluoroethylene (PTFE) prosthesis. The central shunt was chosen because it was an emergency procedure, the sizes of the left and right PAs (LPA, RPA) were borderline, and there were multiple collaterals from th...

Amplatzer Duct Occluder for treatment of displaced PDA coil induced late haemolysis
A 4-year-old child who underwent patent ductus arteriosus (PDA) coil closure for 3 mm PDA (figure 1A) with 052'' cook detachable coil, presented with the features of severe haemolytic anemia 4 months after PDA coil closure. Control angiography performed immediately after the coil deployment and control echocardiography performed 24 h after the procedure showed no residual shunt. A routine follow-up after 3 weeks postprocedure also revealed no residual shunt. No further follow-up was made. The cause for haemolytic anaemia was evaluated in detail and confirmed as residual PDA shunt, likely caused by the d...

A perilous cause for cardiogenic shock
A 34-year-old man with no conventional coronary risk factors was admitted with inferoposterior and right ventricular myocardial infarction with evidence of cardiogenic shock. Patient was taken for emergency primary percutaneous coronary intervention. Because the patient was hemodynamically unstable, direct cannulation of right coronary artery was done, which showed ostioproximal thrombotic occlusion of right coronary artery. After wiring the vessel, thrombus aspiration and subsequent stenting was done. Thrombolysis in myocardial infaction (TIMI) III flow was observed with rapid stabilisation of haemodynamic parameters (fig...

Health-related quality of life of patients after mechanical valve replacement surgery for rheumatic heart disease in a developing country
Conclusions
This first investigation of the HRQoL of people in a developing country after VR surgery for RHD found significant improvement from surgery with this improvement generally sustained. The lack of improvement in mental health requires further exploration as does the influence of an isolated MVR, age and gender. (Source: Heart Asia)
