Abstract
It has remained controversial ever since, with some investigators attesting to the concept that PCWP accurately reflects LAP but others disagreeing, particularly in the setting of mitral valve disease or raised pulmonary vascular resistance. Our study aimed at assessing the correlation between PCWP and LAP in patients with MS in normal sinus rhythm or atrial fibrillation. The trans‐mitral gradients obtained with LAP and that obtained with PCWP were also compared. Evaluation were done both before and after the BMV. This analytical study involved Prior Consent from the patients and was found to be within ethical standards. Data was obtained and studied retrospectively. In this study, we included patients with MS admitted to a tertiary care hospital for BMV during a period of last 3 years. Exclusion criteria were significant chronic respiratory illness or aortic valve disease. Baseline data were collected regarding demographic and clinical characteristics, electrocardiogram, chest X‐ray manifestations, and echocardiographic features. There was no significant difference between mean LAP ‐21.13( 9.2 mmHg) and mean PCWP ‐22.21 (9.4 mmHg) before BMV. Post BMV also, similar result was obtained with a mean LAP 15.2 (7.8mm of Hg) and mean PCWP 17.18 (7.5 mm of Hg). There was good correlation between the mean PCWP and mean LAP before BMV (r = 0.94) (p<0.001) and after BMV (r = 0.84) ( p<0.001). The phasic components of the pressures of LAP and PCWP also showed good correlation before and after BMV. Comparison of mean LAP, mean PCWP and phasic components is shown in Table 2. Furthermore, trans‐mitral gradients assessed by LA–LV and PCWP–LV pressures showed excellent correlation before BMV (r = 0.95) (p<0.001) and after BMV (0.95) (r = p<0.001).In patients with MS, PCWP shows good correlation with LAP. Trans‐mitral gradients obtained with phase‐adjusted PCWP and LAP also correlate well before and after BMV. Hence, PCWP can be used for reliable measurement of trans‐mitral gradient.
