Monomeric oxovanadium(IV) compounds of the general formula cis-[V(IV)(=O)(X)(L(NN))(2)](+/0) [X = OH(-), Cl(-), SO(4)(2)(-) and L(NN) = 2,2'-bipyridine (bipy) or 4,4'-disubstituted bipy].

Reaction of [V(IV)OCl(2)(THF)(2)] in aqueous solution with 2 equiv of AgBF(4) or AgSbF(6) and then with 2 equiv of 2,2'-bipyridine (bipy), 4,4'-di-tert-butyl-2,2'-bipyridine (4,4'-dtbipy), or 4,4'-di-methyl-2,2'-bipyridine (4,4'-dmbipy) affords compounds of the general formula cis-[V(IV)O(OH)(L(NN))(2)]Y [where L(NN) = bipy, Y = BF(4)(-) (1), L(NN) = 4,4'-dtbipy, Y = BF(4)(-) (2.1.2H(2)O), L(NN) = 4,4'-dmbipy, Y = BF(4)(-) (3.

One-year follow-up of a patient with reversible tricuspid valve stenosis due to lymphomatic mass into the right atrioventricular wall.

We present the case of a 66-year-old man with a history of coronary artery disease and chronic lymphocytic leukemia (CLL) who was admitted to the hospital complaining of chest discomfort and shortness of breath on exertion. The echocardiogram revealed a severe pericardial effusion and a large echogenic mass that infiltrated the lateral wall of the right atrium and ventricle and created a moderate tricuspid valve stenosis. B cell intracardiac non-Hodgkin lymphoma/CLL was diagnosed, and the patient was treated with six courses of CHOP chemotherapy.
