A 76 twelvemonth old lady with a recent diagnosing of arthritic mitral valve disease and a history of repeated lower respiratory tract infections, came with symptoms of gastritis unrelated to the primary disease but farther workup in the infirmary revealed atrial fibrillation, grossly dilated left atrium with two big left atrial thrombi and mitral valve country & A ; lt ; 1 cm2. Mitral commissural calcification and important pneumonic high blood pressure were besides noted. After legion treatments it was decided that the best possible attack in our patient was mitral valve replacing with mechanical prosthetic device, despite the usual tendency of utilizing bioprosthesis in aged. The determination was influenced by the fact that patient would necessitate chronic anticoagulation for atrial fibrillation anyhow. The intent of our instance presentation is to exemplify an remarkably late showing instance of arthritic bosom disease with assorted associated complications ensuing in a challenge to take the best possible direction.
Our patient, an aged lady with late diagnosed arthritic mitral valve disease presented with legion challenges in seeking to make up one's mind the best possible intervention: old age, atrial fibrillation necessitating long-run anticoagulation, left atrial thrombi, mitral valve calcification and grossly dilated left atrium. By showing this instance we aim to supply a logical attack in make up one's minding the intervention for similar instances with an accent on old age and long-run endurance benefit. We besides aim to foreground how the intervention should be individualized, taking into consideration all the factors in a peculiar patient.
A 76 year old female, occupant of Mumbai, and a homemaker came to the casualty of Sir JJ Hospital with ailments of 5-6 episodes of purging since forenoon that twenty-four hours. The puke was non-bilious and contained nutrient atoms. Past history was positive for perennial admittances for lower respiratory tract infection and a history of arthritic bosom disease with mitral stricture diagnosed 3 old ages back. The patient did non retrieve holding any symptoms suggestive of arthritic febrility in her childhood.

On scrutiny, she had irregularly irregular pulsation at the rate of 108/minute, blood force per unit area of 100/70 millimeter of Hg, normal jugular venous force per unit area and a pale visual aspect. Chest scrutiny revealed apical urge on the left 5th intercostal infinite and a tangible parasternal haeve and diastolic daze. Auscultation of the thorax revealed first bosom sound ( S1 ) of variable strength, loud P2 and a systolic mutter in the tricuspid country which increased on inspiration.
Electrocardiogram showed right package subdivision block and atrial fibrillation with rapid ventricular rate. Chest X ray showed enormously dilated left atrium and right atrium and ventricle. Computed imaging of the thorax revealed a massively dilated left atrium ( 11 x 10 centimeter ) , right atrium ( 9.5 x 8 centimeter ) and right ventricle with reflux of blood seen in inferior vein cava and hepatic venas. Mitral valve showed calcification. It besides revealed two make fulling defects/thrombi, one attached to the anterior wall of left atrium of size 6.5 ten 3.7 centimeter and 2nd attached to the posterior wall of size 3.2 ten 2.1 centimeter. Consequences of 2D echocardiography included: thickener of mitral valve, mitral valve commissural calcification with a valve country of 0.9 cm2 on planimetry, an echo mark of 8/16 and grounds of thrombi in left atrium- one superiorly 4.6 centimeters x 3.7 centimeters and other attached to the sidelong wall 3.1 centimeter x 2.1 centimeter. M-mode echocardiography showed decreased left ventricular internal dimensions at diastole and systole, decreased terminal systolic and diastolic volumes, a normal expulsion fraction ( 60.2 % ) and the left atrial dimension of 8.6 centimeters x 7.8 centimeter. Colour Doppler showed a mitral valve country of 0.9 cm2, estimated pneumonic arteria systolic force per unit area of 70mm of Hg ( normal: 15-30mm of Hg ) and grade 1 mitral regurgitation.
She was diagnosed as a instance of gastritis in a known instance of arthritic bosom disease and mitral stricture complicated by pneumonic high blood pressure, atrial fibrillation and left atrial thrombi. The gastritis seemed to be unrelated to the implicit in arthritic bosom disease, but the workup drew attending to the primary job of terrible mitral stricture.
The patient later underwent mitral valve replacing with mechanical prosthetic device. She was besides started on anticoagulation with Coumadin with a mark INR scope of 2.0 to 3.0.
Patient showed good recovery in the immediate post-operative period and regular follow up for a month later, showed a good response to the surgery and better ventricular rate control with drugs. There was a gradual autumn in pneumonic arteria systolic force per unit area following surgery.
Arthritic bosom disease has been the cause of important morbidity and mortality in the development states. Bing an autoimmune upset, it has been known to preponderantly impact younger persons following a throat infection with group A streptococcus. Mitral stricture, associated with arthritic bosom disease, can stay symptomless and present every bit tardily as in-between age or beyond. In such instances, the patient may non ever retrieve about an onslaught of arthritic febrility in childhood, giving the feeling of late onset arthritic bosom disease. We report a instance of an aged adult female who was late diagnosed with arthritic bosom disease and mitral stricture. Though it is hard to notice when the disease really started in our patient, we believe that the bosom disease had been benign until its presentation at an age good beyond the usual age of presentation in arthritic bosom disease. By this instance study we besides try to discourse the possible attacks to an aged patient with critical mitral valve disease with important calcification.
Though antecedently symptomless, the demand for intercession in our instance was reiterated by the presence of grossly dilated bosom and important pneumonic high blood pressure. In critical mitral stricture that requires surgery, normally valvular fix is given the first consideration. The challenges in the direction of our patient were: old age, significantly enlarged left atrium, presence of left atrial thrombi, mitral valve country & A ; lt ; 1cm2, mitral valve calcification and pneumonic high blood pressure. Significant calcification of commissures and valve cusp inspissating with decreased cusp country are contraindications to mitral valve fix [ 1 ] . A survey conducted by Wei T and co-workers [ 2 ] concluded that patients with mitral commissural calcification with an echo mark of & A ; acirc ; & A ; deg ; ¤ 8/16 have small betterment in valve country after balloon mitral valvuloplasty, ensuing in a hapless result. Because of the commissural calcification and left atrial thrombi in our instance, it was decided to travel with mitral valve replacing.
The presence of atrial fibrillation with left atrial thrombi raised the possibility of long-run anticoagulation. With grossly dilated left atrium and the chronicity of atrial fibrillation, cardioversion would hold been unsuccessful. Anticoagulation in aged must be used with cautiousness because of important hazard of haemorrhagic complications and the lowest effectual dosage should be used. [ 3 ] Proper monitoring of the dosage and INR is necessary as the effectual dosage for anticoagulation in aged is frequently lower than in the younger topics.
Another inquiry was the pick of prosthetic device: mechanical or biological. In patients & A ; gt ; 70yrs of age, biological valves are preferred [ 4 ] . This is preponderantly because of lower life anticipation in these patients, non-requirement of anticoagulation with these type of valves and lower rates of bioprosthetic impairment in aged [ 4,5 ] .
Sidhu P and co-workers [ 6 ] performed a comparing survey over the long term efficaciousness of mechanical and bioprosthesis over a period of 20 old ages in patients over the age of 70. The survey concluded that bioprosthesis does non supply any survival benefit over mechanical valves in aged. Mechanical prosthetic device has been known to be more lasting but this advantage is offset by anticoagulation-related mortality in patients non necessitating anticoagulation otherwise [ 4,6 ] . Since our patient already required long-run anticoagulation, anyhow, usage of mechanical prosthetic device became possible and suited. [ 7 ]
Figure 5 illustrates an algorithm for taking the type of prosthetic valve in a patient. [ 8 ]
From the instance study and the reappraisal of literature we can reason that:
The presentation of mitral stricture may be delayed as the valve upset may follow a benign class compatible with normal life. It is non uncommon for mitral stricture to show every bit tardily as old age.
Anticoagulation in aged with atrial fibrillation demands to be used with cautiousness. Proper hazard stratification and monitoring are required and the lowest possible dosage of anticoagulation demands to be used.
Balloon mitral valvuloplasty may non be an effectual option in patients with important commissural calcification.
The pick of prosthetic device should be determined on an single footing, sing the presence of co-morbidities and other conducive factors like demand for anticoagulation.
Remember. This is just a sample.
