Predictors of recurrence differ when PFO relatedness is classified by the RoPE score, suggesting that patients with CS and PFO form a heterogeneous group with different stroke mechanisms. Echocardiographic features were only associated with recurrence in the high RoPE score group.

Anticoagulation strategies after BVR are highly variable. In this population, challenges in achieving and maintaining therapeutic warfarin anticoagulation are common, and are associated with an increased risk of bleeding. Further studies are required to clarify the optimal post-BVR anticoagulation strategy.

The study population comprised 5327 digoxin users and 10,654 matched non-users with a median age of 77. During follow-up 10,643 (66.6%) patients died and 7584 (47.5%) patients were readmitted due to HF. Use of digoxin was associated with increased risk of death (hazard ratio (HR): 1.19, 95%-CI: 1.15-1.24) and increased risk of HF readmission (HR: 1.19, 95%-CI: 1.13-1.25). Cumulative incidences of readmission, considering death as a competing risk was 50% for digoxin users and 47% for non-users. The associations applied regardless of concomitant HF treatment. In an exploratory analysis considering patients with previous digoxin use, no effect on mortality (HR: 1.00, 95%-CI: 0.94-1.06), nor on HF readmission (HR: 1.00, 95%-CI: 0.93-1.09) was observed.

The occurrence of disabling stroke, the major fatal consequence of atrial fibrillation, can be reduced by almost two-thirds with warfarin oral anticoagulation. Recent estimates on the prevalence of atrial fibrillation in the USA suggest that approximately 3 million people suffer from this common cardiac arrhythmia, therefore, the socioeconomic impact of adequate oral anticoagulation is enormous. Rivaroxaban, a direct orally available factor Xa inhibitor, is the first of a new class of drugs that target a central factor of the coagulation cascade upstream of thrombin. In the ROCKET AF clinical trial, rivaroxaban demonstrated noninferiority compared with warfarin for stroke prevention in patients with atrial fibrillation, while intracranial and fatal bleeding occurred less frequently with rivaroxaban treatment. Rivaroxban has recently been approved for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation by the US FDA and EMA. Very recently, rivaroxaban in addition to dual antiplatelet therapy, was shown to reduce mortality in patients with a recent acute coronary syndrome in the ATLAS ACS 2-TIMI 51 clinical trial. The clinical evaluation of rivaroxaban in cardiovascular disease and the results of the ROCKET AF study, the landmark clinical trial of rivaroxaban for stroke prevention, are discussed along with the unique pharmacological profile of rivaroxaban.

Those with cyanotic heart disease have an elevated bleeding risk but also are hypercoaguable. Treating haemodynamically significant thrombi in this unique cohort poses a monumental challenge. Case A 29-year-old women with tricuspid atresia and left pulmonary artery atresia presented with superior caval vein syndrome. She had a right modified Blalock-Taussig shunt as a neonate. A left modified Blalock-Taussig shunt performed later failed to establish flow to her left lung. At age 5, she had a Fontan procedure to the right lung but could not tolerate the physiology and had a low cardiac output syndrome. The Fontan was taken down and she was left with a Glenn anastamosis to the right pulmonary artery. She did well for years until she had dyspnea, upper extremity oedema and "facial fullness". On examination she was tachycardic, hypotensive, and more desaturated than baseline. She also had facial plethora. Decision-making Echocardiogram showed a large 9 × 3 mm nearly occlusive thrombus in the superior caval vein at the bifurcation of the left and right innominate veins. An emergent venogram confirmed the location and size of the thrombus. Given the thrombus burden and potential for distal embolisation through the Glenn to the single functional lung, we chose to treat the patient with thrombolytics. She had uncomplicated ICU course and was sent home on warfarin. Follow-up echocardiogram showed complete resolution of clot.

A total of 140 patients completed the questionnaire, 116 patients (83%) reported that they received warfarin education and 61 patients (44%) had a controlled INR. Of the 79 patients with satisfactory knowledge (namely, overall score of at least 75%), 49 (62%) had a therapeutic INR compared with 12 (20%) having unsatisfactory knowledge (p<0.0001). The lowest scores were for participants' knowledge on the effects of a missing dose and its management (42%) and for warfarin drug interactions (36%).

This is the first systematic review on the Taiwanese PNH patients. Our analysis would provide key information about our PNH patients and would help understanding the basic characteristics of this rare disease in Taiwan.
