Cardiac involvement of diffuse large B-cell lymphoma presenting as various arrythmias.

Symptomatic cardiac involvement of malignant lymphoma is rare. Silent invasion of malignant lymphoma makes it difficult to diagnose it in the early phase of clinical course. We describe a case with cardiac involvement of diffuse large B-cell lymphoma presenting various types of arrythmias that were not diagnosed until autopsy.

Twice- or once-daily dosing of direct oral anticoagulants and gastrointestinal bleeding in patient with atrial fibrillation.

Aims: Direct oral anticoagulant (DOAC) is widely used for the prevention of embolic stroke in non-valvular atrial fibrillation (NVAF) patients. However, the gastrointestinal bleeding risk in several DOAC regimens was higher than warfarin, especially in once-daily regimens.

Methods And Results: We conducted a single-center prospective registry of patients with NVAF treated with DOACs: the DIRECT registry (N = 2216; follow-up duration 650 [IQR 103-1574] days, UMIN000033283).

Synergistic mechanism of coincidence of two subacute stent thromboses: Insights from multiple imaging observations.

In the drug-eluting stent era, stent thrombosis is uncommon but still a life-threatening complication after percutaneous coronary intervention. There are several types of risk factors associated with stent thrombosis, which could work synergistically to produce thrombus. We report the case of subacute stent thrombosis.
