Desmopressin acetate (1-deamino-8-D-arginine vasopressin [DDAVP]) improves hemostasis in hemophilia A and von Willebrand's disease and in some platelet disorders. In complex cardiac operations, excluding simple coronary artery bypass graft procedures, we found that desmopressin reduced blood loss by 40% and the need for transfusion by 34%. Conflicting reports followed. Future trials should emphasize patients with excessive bleeding. A possible post-desmopressin prothrombotic state was studied after hip replacement surgery. The incidence of deep vein thrombosis associated with warfarin sodium therapy was the same as that associated with desmopressin plus warfarin therapy. No desmopressin-induced thrombotic tendency was detected. A trend toward reduced blood loss with desmopressin was not significant. During cardiac catheterization, the plasma von Willebrand factor level was correlated with hemodynamic variables, including pulmonary vascular resistance, pulmonary arterial pressure, and (inversely) with cardiac index. von Willebrand factor concentration was highest in mitral stenosis. The relationship of these factors to the response to desmopressin remains to be defined.

The antiphospholipid antibody syndrome (APS) may present with serious cardiovascular complications which should be recognised by the cardiologist. The authors report a series of 6 cases of APS diagnosed after thrombotic events and the finding of antiphospholipid antibodies. The APS was primary in 5 cases and associated with tuberculous lymphadenitis in 1 case. There was cardiac involvement in 5 patients with pericardial effusion in 3 cases, complicated by tamponade as the presenting sign of primary APS in the other 2, valvular disease in one case (moderate mitral stenosis with aortic valve disease) and pulmonary embolism in one case. Five patients developed recurrent deep vein thrombosis of the legs. One patient had a transient ischaemic cerebral attack.

Anticoagulant treatment is extremely important and frequently encountered in the therapy of various cardiovascular diseases. Vitamin K antagonists (VKA) are in use for the prevention and treatment of arterial and venous thromboembolism, despite the introduction of new direct-acting oral anticoagulants (NOAC). The VKA still have the clear recommendation in patients with a mechanical prosthetic heart valve replacement or moderate to severe mitral stenosis of the rheumatic origin, in deep vein thrombosis associated with congenital thrombophilia, and in cases where NOAC are prohibited by social condition (financial reason) or by comorbidities (extreme weight, severe renal or liver disease). VKA dosing required to reach the targeted therapeutic range varies largely between patients (inter-individual variability). This inter-individual variability depends on multiple environmental factors such as age, mass, diet, etc. but it is also influenced by genetic determinism. About 30 genes implicated in the metabolism coumarins derivatives were identified, the most important being CYP2C9 and VKORC, each with several polymorphisms. Herein, we review the data regarding genetic alterations in general and specific populations, highlight the diagnosis options in particular cases presenting with genetic alteration causing higher sensitivity and/or resistance to VKA therapy and underline the utility of NOAC in solving such rare and difficult problems.
