Transaortic Shallow Septal Myectomy and Cutting of Secondary Fibrotic Mitral Valve Chordae-A 5-Year Single-Center Experience in the Treatment of Hypertrophic Obstructive Cardiomyopathy.

Background: Anomalies of the mitral apparatus have been shown to contribute to left ventricular outflow obstruction in patients with hypertrophic cardiomyopathy (HCM). We report our 5-year single-center experience with a shallow myectomy procedure associated with transaortic mitral valve repair in a cohort of HCM patients.

Methods: We studied 83 consecutive patients who underwent surgical treatment of symptomatic left ventricular outflow obstruction.

Current management and surgical advances in patients with hypertrophic obstructive cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is a genetic disease and the most frequent primary cardiomyopathy, affecting 1:500 of the general population. Integrated multimodality imaging, including transthoracic echocardiography, 2- and 3‑dimensional transesophageal echocardiography, stress echocardiography, and cardiac magnetic resonance, has provided answers to questions on the management of HCM, leading to standardized protocols. The late 1990s brought the news of a nonsurgical treatment of obstruction in HCM.

The mechanisms, diagnosis and management of mitral regurgitation in mitral valve prolapse and hypertrophic cardiomyopathy.

Valvular disease is a frequent cardiac pathology leading to heart failure and, ultimately, death. Mitral regurgitation, defined as the inability of the two mitral leaflets to coapt, is a common valvular disease and a self sustained pathology. A better understanding of the mitral valve histological layers provides a better understanding of the leaflet and chordae changes in mitral valve prolapse.

Adapting a geographical information system-based water resource management to the needs of the Romanian water authorities.

Background, Aim, And Scope: The need for global and integrated approaches to water resources management, both from the quantitative and the qualitative point of view, has long been recognized. Water quality management is a major issue for sustainable development and a mandatory task with respect to the implementation of the European Water Framework Directive as well as the Swiss legislation. However, data modelling to develop relational databases and subsequent geographic information system (GIS)-based water management instruments are a rather recent and not that widespread trend.
