Features of degenerative mitral valve prolapse in the North East of China: repair characteristics, and short-term follow-up results.

Background: We aimed to assess the clinical and echocardiographic characteristics of patients who underwent surgery for degenerative mitral valve prolapse (MVP) in our center, and its relation to outcomes.

Methods: We enrolled 117 consecutive patients from North-East China with an echocardiographic diagnosis of MVP related mitral regurgitation (MR) between April 2018 and November 2019. A complexity scoring system was used for valve anatomy, and patients were re-evaluated at 3-6 months after surgery.

Can Perceval sutureless valve reduce the rate of patient-prosthesis mismatch?†.

Objectives: The aim of this study is to compare the theoretical incidence of patient-prosthesis mismatch (PPM) in patients undergoing a sutureless or a sutured aortic valve replacement using an exact statistical matching.

Methods: Between May 2012 and March 2016, 65 patients with severe symptomatic aortic stenosis underwent a sutureless aortic valve replacement with the Perceval bioprosthesis in 2 centres. Moreover, 177 aortic valve replacements with conventional sutured bioprosthesis were performed between August 2003 and September 2015.

Takotsubo Cardiomyopathy Following Pericardiocentesis After Aortic Valve Repair and Ascending Aorta Replacement.

Takotsubo cardiomyopathy is a reversible cardiomyopathy, which generally developes in menopausal women and is characterized by left ventricle dysfunction with apical ballooning in the absence of coronary artery disease. It is often triggered by a stressful event, and its clinical presentation resembles acute anterior myocardial infarction. This condition is a rare adverse event of cardiac operations, and only a few cases are described in the literature, especially after mitral valve operations.

Aortic sutureless Perceval valve for small root in concomitant mitral valve replacement.

Conventional valves have a sewing ring that reduces the effective orifice area for a given valve size. In patients with small aortic roots, the implantation of a stented conventional prosthesis can be very difficult or may lead to patient-prosthesis mismatch. In the case of the Sorin Perceval sutureless aortic valve, concomitant mitral valve replacement (MVR) is an exclusion criterion because the latter valve's rigid ring may interfere with the self-expandable stent anchorage of the Sorin Perceval sutureless valve, or cause it to become distorted.

[Cardiovascular involvement in Erdheim-Chester syndrome: clinical and therapeutic implications].

Erdheim-Chester disease (ECD) is a rare form of non-Langerhans' cell histiocytosis of unknown etiology and its incidence is constantly increasing. ECD is characterized by a xantomatous or xanthogranulomatous infiltration of various tissues by foamy histiocytes surrounded by fibrosis. ECD is characterized by multi-organ involvement and is generally associated with a poor prognosis with a median survival of 32 months after diagnosis.
