Balloon venoplasty for disdialysis syndrome due to pacemaker-related superior vena cava syndrome with chylothorax post-bacteraemia: A case report.

Background: Although superior vena cava (SVC) syndrome has also been reported as a late complication of pacemaker (PM) implantation, acute onset of SVC syndrome caused by disdialysis syndrome in patients with PM implantation is very rare. There are no specific therapies or guidelines.

Case Summary: A 96-year-old woman receiving dialysis was implanted with a PM due to sick sinus syndrome.

Synthesis and Activity of 2-Acyl-cyclohexane-1,3-dione Congeners Derived from Natural Products against the Plant p-Hydroxyphenylpyruvate Dioxygenase Herbicidal Molecular Target Site.

Plastoquinone is a key electron carrier in photosynthesis and an essential cofactor for the biosynthesis of carotenoids. p-Hydroxyphenylpyruvate dioxygenase (HPPD) is a vital enzymatic step in plastoquinone biosynthesis that is the target of triketone herbicides, such as those derived from the pharmacophore backbone of the natural product leptospermone. In this work, the inhibitory activity of a series of 2-acyl-cyclohexane-1,3-diones congeners derived from natural products was tested on plant HPPD.

A rare case of stiff left atrial syndrome caused by both coconut left atrium and vertebral compression: a case report.

Background: Calcification of the left atrium (LA) is a rare condition and can be the result of long-standing rheumatic mitral stenosis or an unusual complication after mitral valve replacement. Cases of massive LA calcification have sometimes been referred to as those with 'coconut LA' or 'porcelain LA'.

Case Summary: A 75-year-old woman was referred to our hospital because of chest discomfort and exertional dyspnoea.

Successful Triple Combination Immunosuppressive Therapy with Prednisolone, Cyclosporine, and Mycophenolate Mofetil to Treat Recurrent Giant Cell Myocarditis.

A 59-year-old man with a history of giant cell myocarditis was admitted to our hospital with recurrent giant cell myocarditis triggered by a 1 mg/day taper in his prednisolone dose. During the initial episode, he had undergone rescue implantation of a temporary left ventricular assist device followed by the administration of dual immunosuppressive therapy with prednisolone and concomitant cyclosporine. Triple combination immunosuppressive therapy maintained with additional mycophenolate mofetil successfully controlled recurrent myocarditis, enabled a reduction in the prednisolone dose, and achieved the functional recovery of the left ventricle.

Combined assessment of left atrial volume parameters for predicting recurrence of atrial fibrillation following pulmonary vein isolation in patients with paroxysmal atrial fibrillation.

Objectives: Our aim was to test the hypothesis that comprehensive simplified left atrial (LA) assessment derived from routine echocardiography may be more useful than assessment of LA volume alone for predicting atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI).

Methods: We studied 156 patients with paroxysmal AF (PAF) who had undergone PVI. Echocardiography was performed within two days before PVI.
