    Holt-oram syndrome with hemizygous continuation of inferior vena cava.
    (Asian cardiovascular & thoracic annals, 2006)
    A rare and previously unreported combination of Holt-Oram syndrome, atrial septal defect, patent ductus arteriosus, isolated left atrial isomerism and inferior vena caval interruption with hemizygous continuation to the left superior vena cava is described.

    Percutaneous Treatment of Congenital Coronary Arteriovenous Fistulas
    (JOURNAL OF INTERVENTIONAL CARDIOLOGY, 2011)
    Methods and results: Six patients (two males) with congenital coronary arteriovenous fistulas (CAVF) underwent percutaneous transcatheter occlusion. The ages ranged from 4 years to 49 years (mean 20.1 years). The fistulas had their origins from the right coronary artery (two), the left anterior descending coronary artery (two), and the left circumflex coronary artery (two). One of the fistulas drained to the right ventricle, four drained to the right atrium, and the remaining one to the left ventricle (LV). The fistulas were closed using the arterial approach with Cook (TM) coils in two patients and with nitinol ductal occluders (NDOs) using the venous approach in four patients. One patient developed dissection of the wall of the fistula during attempted closure and had spontaneous occlusion of the fistula. Complete occlusion of the fistulas were achieved in all patients. Complications consisted of migration and embolization of the coils in one patient (later closed successfully with NDO) and myocardial infarction occurring two weeks following successful closure in another patient. At mean follow-up of 39.6 +/- 22.9 months, all patients were asymptomatic and echo-Doppler evaluation revealed no residual fistulae.Conclusions: CAVF are very well amenable to percutaneous closure with acceptable morbidity and high success rates.

    Tako-tsubo cardiomyopathy in a patient with myasthenia gravis crisis: a rare clinical association.
    (BMJ case reports, 2009)
    Tako-tsubo cardiomyopathy (TTC) is increasingly being recognised as transient left ventricular dysfunction following various hyperadrenergic states such as emotional or physical stressors. The association of this rare clinical entity with myasthenia gravis (MG) has been reported only twice in the literature, both following plasmapheresis for MG crisis. Here we describe a unique case of TTC in a 40-year-old woman with MG admitted with MG crisis managed conservatively. This case suggests that plasmapheresis is unlikely to have a causative role in the development of TTC in these patients. Patients with MG crisis may be at potential risk of developing TTC and careful clinical and electrocardiographic monitoring is necessary while treating them. The possible role of stress as the common precipitating factor in both conditions is also discussed.
