In situ oxidative stress and atrial cell deaths in patients with valve disease.

CONCLUSIONS: The findings suggests that oxidative stress originating from in situ leukocytes within the atrial myocardium may be the potential trigger for excessive transcriptional activities and apoptotic cell death within the atrial myocardium of valve disease patients. This represents a potential therapeutic target. PMID: 30033881 [PubMed - as supplied by publisher]

We report the case of a 47-year-old man who was diagnosed with severe right ventricular outflow tract (RVOT) stenosis due to a space-occupying lesion; the diagnosis was made using computed tomography. He underwent mass reduction, pulmonary valve replacement, and RVOT reconstruction with a bovine pericardial patch. The pathological diagnosis was undifferentiated pleomorphic sarcoma originating from the myocardium. As the mass resection was incomplete, he received heavy particle therapy. He did not want to receive adjuvant chemotherapy. Four months later, severe RVOT stenosis recurred because the residual mass had invaded th...

AbstractPurpose of reviewAs the number of surgical and transcatheter valve replacements continue to increase in the aging population, so does the incidence of paravalvular leak (PVL). Given its impact on morbidity and mortality, this article will focus on the epidemiology, clinical presentation, diagnostic assessment, and available treatments for PVL.Recent findingsDespite being performed on inoperable and typically higher risk patients, short-term complication rates of transcatheter PVL closure appear relatively low (

We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding. Treatment involves initial correction of anemia and heart failure followed by aortic valve replacement. The prosthesis used depends on the characteristics of each patient and valve replacement allows the resolution of bleeding in most cases. Gastrointestinal bleeding in patients with aortic stenosis is associated with severity of the valve obstruction. A mechanical prosthesis was used with no recurrent bleeding even with the need for lifelong anticoagulation therapy.

Abstract Background: Mitral valve repair in paediatric patients with chronic rheumatic heart disease is superior to valve replacement and has been used with good results. Objective: To identify predictors of unfavourable outcomes in children and adolescents submitted to surgical mitral valvuloplasty secondary to rheumatic heart disease. Methods: Retrospective study of 54 patients under the age of 16 operated at a tertiary paediatric hospital between March 2011 and January 2017. The predictors of risk for unfavourable outcomes were: age, ejection fraction, degree of mitral insufficiency, degree of pulmonary hypertension, pr...

LV dysfunction is one of the most commonly used terminology by cardiac professionals.It can be systolic, diastolic or global, regional etc. But, before dysfunction sets in, the heart fights. The Left ventricle can behave in many different ways when confronted with stress. It increases the force of contraction, elevates it’s Intra cavitary filling pressure and still accomplishes its task of pumping adequately. Further, It can build fresh muscle (LVH). It can double up with more heartbeats. (All these factors are referred to as cardiac reserve mechanisms) These reserve mechanisms can be activated in the short or l...

Authors: Jiao Y, Luo T, Zhang H, Han J, Li Y, Jia Y, Zheng S, Meng X Abstract Background: We compared and analyzed differences between repair vs. replacement of mitral valves on severe rheumatic mitral stenosis by looking at mid-term clinical outcomes. Methods: Patients with severe rheumatic mitral stenosis (mitral valve area ≤1.5 cm2, with or without mitral valve regurgitation) from January 2011 to September 2017 were divided into two groups: a mitral valve repair group (MVP) and a mitral valve replacement group (MVR). After propensity score matching between the two groups, we compared changes in post-opera...
