Mitral valve (MV) disease is the most common form of heart valve disease, occurring in approximately 2% of the population and resulting in 43,000 open-chest surgical procedures every year [1]. One subtype is mitral valve prolapse (MVP), which is often characterized by severe regurgitant flow, thickened and enlarged leaflets, and disrupted and mechanically compromised collagen architecture.

In this paper we discussed the heart valve disease. This heart valve disease occur throughout the world due to the more ethical estimation and grow curator of heart valve diseases use the diagnosis for this type of valve disease . Actually Phonocardiogram (PCG) signals are used because it having less price and acquire the signals. In this we learn five different kind of heart areas, Also typical are aortic stenosis, mitral valve prolapse, mitral stenosis and mitral regurgitation.

Abstract Background Mitral valve disease is the most common heart valve disease worldwide. Heart valve operation is the predominant treatment strategy for heart valve disease. This study analyzed the death risk from heart valve disease with respect to the frequency of heart valve operation and other operations in patients with mitral valve disease. Materials and methods We conducted a retrospective nationwide population-based case–control study using a claims dataset from Taiwan’s National Health Insurance Research Database. The case and control groups enrolled mitral valve disease patients from 2002 to 2013 who had either underwent an heart valve operation procedure or not, respectively. Conditional logistic regression was estimated the odds ratios (ORs) associated with various risk factors for heart valve operation-related death, including other operations and comorbidities. Results A total of 25,964 patients with mitral valve disease were recruited for the study and divided into heart valve operation (600 patients) and non-heart valve operation (25,364 patients) groups. After matching, a total of 1800 non-heart valve operation patients were selected for final analysis. Heart valve operation was associated with decreased risk of death (adjusted OR [aOR] 0.439), but operations related to other cardiovascular disease (CVD, aOR 3.691), respiratory conditions (aOR 3.210), and the urinary system (aOR 1.925) were associated with increased risk of death for patients with mitral valve disease. Patients with mitral valve disease and diabetes (aOR 1.505), chronic kidney disease (CKD, aOR 3.760), or emphysema (aOR 2.623) also had a higher risk of death. Patients who underwent more heart valve operations had a lower risk of death from mitral valve disease, but patients who underwent more other operations had a higher risk of death from mitral valve disease. Conclusions The death risk for patients with mitral valve disease patients could be lowered by more frequently performing heart valve operations. However, the risk of death is increased for patients with mitral valve disease who more frequently undergo other operations, chiefly those for other CVD system, respiratory conditions, and urinary system, or have comorbidities such as diabetes, chronic kidney disease, and emphysema.

Background Patients who survive long after pneumonectomy may develop heart valve disease. The consecutive operations can be complex because of the challenging anatomical conditions and the limited physiologic reserves of the patient. Case Presentation The subject is a 78-year-old patient who underwent a left-sided pneumonectomy for a metastasized testicular tumor 50 years ago. At 32 and 37 years postpneumonectomy, mitral regurgitation was manifested, and valve repair was performed. Bioprosthetic mitral valve replacement and tricuspid valve reconstruction became necessary 44 years postpneumonectomy. The patient was fully recovered. Conclusion In case of relevant heart valve disease after pneumonectomies, heart valve surgeries are feasible.
