Factors indicating changes in mitral valve area after single-balloon percutaneous transvenous mitral commissurotomy (PTMC) were evaluated in 53 patients receiving PTMC by follow up for 3-48 months (mean 18 +/- 12 months) using serial transthoracic echocardiography to measure mitral valve area by planimetry. The echocardiographic scores of the mitral commissures and mitral valve, and other clinical variables were assessed. Mitral valve area showed an immediate increase from 1.1 +/- 0.3 to 1.8 +/- 0.3 cm2 (p < 0.01). There was a small but significant decrease in mitral valve area at follow-up to 1.6 +/- 0.4 cm2 (p < 0.01). Restenosis (a decrease in mitral valve area of more than 25% from immediately after PTMC to follow-up) occurred in nine patients (17%). There was no significant correlation between clinical or echocardiographic features and an increase in mitral valve area immediately after PTMC. The total echocardiographic score of the mitral commissures correlated with the decrease in mitral valve area at follow-up (r = 0.42, p = 0.002). Multiple regression analysis showed the total echocardiographic score of the mitral commissures was the best indicator of a decrease in mitral valve area at follow-up (p = 0.0059). Six of nine patients with restenosis had a commissure score of more than 3, while only five of 44 patients without restenosis had a commissure score of more than 3 (p < 0.01). Mitral valve area increases significantly immediately after PTMC, and decreases significantly at follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)

D008946 Mitral Valve Stenosis Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D002404 Catheterization Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions. Cannulation,Cannulations,Catheterizations
