Mitral regurgitation (MR) is a frequent complication of end-stage heart failure. Historically, these patients were either managed medically or with mitral valve replacement, both associated with poor outcomes. Mitral valve repair via an 'undersized' annuloplasty repair is safe and effectively corrects MR in heart-failure patients. All of the observed changes contribute to reverse remodeling and...

Pulmonary valve movement and the related acoustic phenomena were investigated using high speed strip-chart echoand phonocardiographic recording. The opening of the pulmonary valve had no definite relationship to the acoustic phenomena, whereas the pulmonary ejection sound was closely related in time to the early systolic maximal opening of the valve. The concomitant pulmonary ejection systolic ...
Ann Cardiothorac Surg 2013;2(6):857 www.annalscts.com Background The mitral valve controls the direction and flow of blood through the left chambers of the heart. If the valve becomes too hard (calcified) and too narrow (stenosis), flow will be reduced; if the valve becomes too loose, flow might travel backwards (regurgitation). Abnormal blood flow will force the heart to work harder, eventuall...
Correspondence to Professor P Lancellotti; [email protected] The growing prevalence of valvular heart disease represents a major challenge in terms of short-term and long-term management and surveillance. 2 Despite welldefined guidelines, appropriate detection and follow-up strategies are still poorly applied in valvular heart disease. 4 In many countries, valvular heart diseases are m...
BACKGROUND Valvular heart disease is a leading cause of cardiovascular mortality, especially in China. More than a half of valvular heart diseases are caused by acute rheumatic fever. microRNA is involved in many physiological and pathological processes. However, the miRNA profile of the rheumatic valvular heart disease is unknown. This research is to discuss microRNAs and their target gene pat...
surgery for heart diseases during pregnancy, especially necessitating cardiopulmonary bypass, is believed to trigger maternal and fetal risks and should be performed only when medical therapy has been unsuccessful to alleviate the cardiac decompensation. a 33-year-old pregnant woman in her 33rd week of gestation was admitted to our hospital. she had rheumatic mitral valvular stenosis and had un...
Aortic valve disease is a fatal disease with but a single cure. Removal of the mechanical obstruction in aortic stenosis (surgery or TAVI) and replacement of an incompetent valve (so far only surgery) are the only treatment options. While aortic valve replacement in patients with isolated valve disease and normal pumpfunction of the heart has become a routine procedure and is performed with exc...
The calculated systolic, diastolic and mean pulmonary artery pressure, the ratio of sizes right left ventricles heart, eccentricity index ventricle, systolic excursion fibrous ring tricuspid valve, movement myocardium at level valve area atrium are main echocardiographic indicators for assessing idiopathic similar forms hypertension according to current Russian, Eurasian European guidelines in ...
we report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. we present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery – the theories and treatments are discussed. a 85 year-old female was admitted under the care of the cardiothoracic team with signs ...
