Fatal right-sided heart failure due to leukostasis in a patient with leukemic transformation of myelodysplastic syndrome.

We document leukostasis leading to acute fatal right-sided heart failure. In patients presenting with leukostasis and cardiopulmonary symptoms, clinicians should aim to assess for cardiac involvement, that is, by ECG and acute echocardiogram, since early recognition of right ventricular disease may provide an opportunity to treat this potentially reversible condition.

Three-dimensional multidetector computed tomography versus conventional 2-dimensional transesophageal echocardiography for annular sizing in transcatheter aortic valve replacement: Influence on postprocedural paravalvular aortic regurgitation.

Objectives: In transcatheter aortic valve replacement (TAVR), the influence of aortic annular assessment with either multidetector computed tomography (MDCT) or conventional transesophageal echocardiography (TEE) on the incidence of postprocedural paravalvular aortic regurgitation (PAR) was evaluated.

Background: PAR remains a major limitation in TAVR. Appropriate selection of transcatheter heart valve (THV) size is crucial to prevent PAR.

The content of docosahexaenoic acid in serum phospholipid is inversely correlated with plasma homocysteine levels in patients with end-stage renal disease.

Patients with end-stage renal disease (ESRD) have a high morbidity and mortality from cardiovascular disease. An elevated homocysteine level is an independent predictor of cardiovascular events in patients with ESRD. Interestingly, some studies have found an inverse relationship between the content of marine n-3 polyunsaturated fatty acids (PUFAs) and homocysteine levels, but data are ambiguous.

Amino acid transamination is crucial for ischaemic cardioprotection in normal and preconditioned isolated rat hearts--focus on L-glutamate.

We have found that cardioprotection by l-glutamate mimics protection by classical ischaemic preconditioning (IPC). We investigated whether the effect of IPC involves amino acid transamination and whether IPC modulates myocardial glutamate metabolism. In a glucose-perfused, isolated rat heart model subjected to 40 min global no-flow ischaemia and 120 min reperfusion, the effects of IPC (2 cycles of 5 min ischaemia and 5 min reperfusion) and continuous glutamate (20 mm) administration during reperfusion on infarct size and haemodynamic recovery were studied.
