Correlation between Vertebral Left Atrial Size and NT-proBNP in Dogs with Myxomatous Mitral Valve Disease

Aim: To study the correlation between Atrial Fibrillation (AF) and left atrial size in Rheumatic Mitral valve disease (RMVD). Background: AF is the most common sustained cardiac arrhythmia which is associated with increased cardiovascular morbidity, mortality and preventable stroke. AF is common in rheumatic heart disease (RHD) particularly mitral stenosis (MS). LA dilatation is the predisposing factor for the development of AF in RMVD. Methodology: This is a hospital based cross sectional descriptive study conducted in 52 patients who were diagnosed as RMVD clinically and echocardiographically in NGMCTH, Kohalpur between December 2018 to November 2019. Detailed history and complete clinical examination were performed. Standard 12 lead ECG and 2-D echocardiography were done. Left atrial size was measured and compared with patients in AF and with sinus rhythm. Result: The age of patients ranged from 20-76 years with the mean age of 40.33 years. Out of 52 patients 30 were in AF and 23 in sinus rhythm. Among 30 patients in AF, 27 (90%) had LA size ≥ 4 cm with mean LA size of 4.6 cm whereas among 22 patients in sinus rhythm, 14 (63.64%) had LA Size <4 cm with a mean of 3.83 cm. Conclusion: Left atrial size ≥ 4 cm is the predisposing factor for the development of AF in rheumatic mitral valve disease. Therefore, if patients in sinus rhythm who are at high risk of developing AF are identified, prophylactic anticoagulation and antiarrythmic drug might prevent AF induced embolism and exacerbation of symptoms in rheumatic mitral valve disease.

Atrial Size

Background: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia which is as associated with increased cardiovascular morbidity, mortality and preventable stroke. AF is common in rheumatic heart disease (RHD) particularly mitral stenosis (MS). Left atrial (LA) dilatation is the predisposing factor for the development of AF in rheumatic mitral valve disease. Aim was to study the correlation between AF and LA size in rheumatic mitral valve disease in the population of Southern Andhra Pradesh. Methods: This is a prospective, observational study conducted in 42 patients diagnosed to have RMVD in Narayana Medical College and Hospital, Nellore, Andhra Pradesh between August 2018 and July 2020. Detailed patient history and complete clinical examination were performed. Standard 12 lead Electrocardiography (ECG) and 2-D echocardiography were done. Left atrial size was measured and compared with patients in AF and with sinus rhythm. Results: The age of patients ranged from 20-76 years with the mean age of 40.33 years. Out of 42 patients 26 were in AF and 16 in sinus rhythm. Among 26 patients in AF, 22 (84.6%) had LA size ≥4 cm and 4 (15.38%) had <4 cm with mean LA size of 4.6 cm whereas among 16 patients in sinus rhythm, 10 (62.5%) had LA size <4 cm and 6 (37.5%) had ≥4 cm with a mean of 3.83 cm. Conclusions: Left atrial size ≥4 cm is the predisposing factor for the development of AF in rheumatic mitral valve disease. Therefore, if patients in sinus rhythm who are at high risk of developing AF are identified, prophylactic anticoagulation and antiarrythmic drugs might prevent AF induced complications like embolism and symptom exacerbation in rheumatic mitral valve disease.

The Impact

Background: Rheumatic mitral valve disease (mitral stenosis or regurgitation) remains the common heart disease in developing countries. Mitral valve is involved in 99% of cases. The prognostic implication of LA (left atrium) size has also been shown in high-risk subgroups, such as patients with acute myocardial infarction, atrial arrhythmia, LV dysfunction, or dilated cardiomyopathy, and patients undergoing valve replacement for aortic stenosis and mitral regurgitations. Objective of the study was to study the impact of left atrial size reduction in patients undergoing mitral valve surgery for mitral valve disease with left atrial enlargement on clinical outcome and echocardiographic parameters.Methods: A prospective study was done at department of cardiovascular and thoracic surgery, Sri Venkateshwara institute of medical sciences, Tirupati from June 2012 and June 2013.The study population consisted of patients with rheumatic mitral valve disease with or without tricuspid valve disease with left atrial size enlargement who underwent mitral valve surgery alone and mitral valve surgery with left atrial reduction. Twenty consecutive subjects were taken in each group during the study period. Results: The age range is 21 to 61 years. There means age is 39.7±10.3 years. in the study group. Following MVR significant improvement in the NYHA (New York Heart Association) functional class was noted in all the patients. The decrease in RVSP, LA size, and TR was noted in all the patients.Conclusions: It seems reasonable to suggest that patients who undergo LA reduction along with MVR have significant improvement in clinical outcome and NYHA functional class with less thromboembolic complications during long term follow up.
