Left atrial structural and functional remodeling following balloon mitral valvuloplasty.

Mitral stenosis (MS) is associated with left atrial (LA) functional and morphological changes as a result of chronic increase in LA pressure. Relieving the mitral obstruction via balloon mitral valvuloplasty (BMV) might be associated with LA structural and functional remodeling. To study alterations of LA volume and functions 1 year following successful BMV in patients with isolated rheumatic severe mitral stenosis.

Impact of balloon mitral valvuloplasty on left ventricular rotational deformation: Magnetic Resonance Imaging follow up study.

In patients with rheumatic mitral stenosis (MS), some previous studies have investigated the influence of balloon mitral valvuloplasty (BMV) on left ventricular (LV) systolic function. However, the impact of BMV on LV twisting motion in this clinical setting has not been studied before yet. To describe changes in LV torsion in patients with rheumatic MS following BMV.

Mitral balloon valvuloplasty.

Percutaneous mitral balloon valvuloplasty (MBV) was introduced in 1984 by Inoue who developed the procedure as a logical extension of surgical closed commissurotomy. Since then, MBV has emerged as the treatment of choice for severe pliable rheumatic mitral stenosis (MS). With increasing experience and better selection of patient, the immediate results of the procedure have improved and the rate of complications declined.

Cardiac unilateral pulmonary edema: is it really a rare presentation?

Unilateral pulmonary edema is a distinctly unusual clinical entity that presents interesting and confusing diagnostic challenges. It is usually described as occurring with re-expansion of a collapsed lung after rapid thoracocentesis of pleural air or pleural fluid. Unilateral pulmonary edema as an initial presenting manifestation for heart failure is uncommon and can be confused with other more common causes of alveolar or interstitial infiltrate, which can lead to a significant delay in treatment.
