  • Outlook (Prognosis)The outcome varies. The disorder may be mild, without symptoms, or may be more severe and eventually disabling. Complications may be severe or life threatening. Mitral stenosis is usually controllable with treatment and improved with valvuloplasty or surgery.Possible ComplicationsAtrial fibrillation and atrial flutterBlood clotsto the brain (stroke), intestines, kidneys, or other areasCongestive heart failurePulmonary edemaPulmonary hypertension

    General Data: 30 year old Filipino male from MakatiChief Complaint: difficulty of breathing

    *HPI: 2 months prior to consult, the patient started to note easy fatigability and shortness of breath when at work, forcing him to take frequent breaks. He also noted palpitations accompanied by chest pain occurring even at rest. One month prior to consult, he noted progression of symptoms, now occurring more frequently and with less activity. He also noted waking up from sleep due to not getting enough air. When he consulted his family doctor, he was given Seretide inhaler to be used twice a day. Symptoms persisted despite medications, prompting present consult.

    SERETIDE = Fluticasone + Sameterol ( Not used for acute asthma symptoms) *ROS: (+) nonproductive cough for 3 weeks especially when supine, (-) fever, (-) headache/dizziness, (+) episode of near-syncope few weeks ago, (-) abdominal pain, (-) changes in bowel character, (-) dysuria, (+) swelling of both feet, (-) joint pain

    (+) nonproductive cough for 3 weeks especially when supine = PAROXYS(+) episode of near-syncope few weeks ago(+) swelling of both feet*PHx: nonsmoker, no intake of alcoholic beverage, currently works as a manager in JollibeePast Medical Hx: (+) asthma recently diagnosed and maintained on Seretide BID, (-) hypertension, diabetes, allergies**** It is important to ask the patient if he had a history of scarlet fever or sore throat that was poorly treated before way back 5-10 years agoFamily Hx: (+) heart disease mother, died at 45 years old, (-) HPN, diabetes, asthma**** Ask the patient the specific cause of death of the patient, his mother dying early due to heart disease can be an indication that the patient might have a congenital heart disease such as

    *Physical Exam:General Survey: conscious, coherent, ambulatory, very anxiousVital Signs: BP=90/60HR=102/min, irregularly irregularRR=24/minTemp: 36.8oCWeight: 46 kgHeight: 155cmHEENT: pink palpebral conjunctivae, icteric sclerae, no cervical lymphadenopathySkin: good skin turgor, no lesionsNeck: no carotid bruits, brisk upstroke of carotid pulse, JVP=5 cm at 30oVery anxious = caused by difficulty of breathing or not feeling well, agitationBP = hypotensive = HR = tachycardic, irregularly irregular (atrial fibrillation???) = compensation for low cardiac outputRR = tachypnic = compensation for low cardiac output BMI = healthy46/2.425 = 18.9 = healthy weight range for asians (asian diabetes initiative)Icteric sclerae = jaundiceJVP=5 cm at 30o = increased right atrial pressure/ central venous pressureIcteric sclerae = jaundice (liver damage)

    *Lungs: equal chest expansion, no retractions, equal tactile fremitus both lung fields, resonant to percussion on both lung fields, (+) fine bibasilar crackles on both lungfieldsCardiac: (+) RV heave, no thrills, apex beat at the 5th ICS 2 cm lateral to the left midclavicular line, loud S1 at apex, prominent P2 at the base, (+) gr 3/6 middiastolic rumble at apexExtremities: (+) gr 1 bipedal edema, dorsalis pedis pulse (+2), no clubbing, no cyanosis

    Fine basilar crackles = wet lungs, PULMONARY EDEMA(+) right ventricular heaves = increase AV impulseprominent P2 at the base = pulmonics component of second heart sound accentuated, pulmonary hypertensionGrade 3/6 Mid diastolic rumble (apex) = disproportion between valve orifice sizes and flow rate in mitral/tricuspid valves; duration is index of severity of valve obstructionGrade 1 Bipedal edema = Right Heart FailureLoud S1 (apex) = position of mitral leaflets (onset ventricular systole)*Subc nodules in severe carditis of RFMitral facies of MSNeuro exam and oral ulcers for SLE >>>SOAP BRAIN MD mnemonics

    Duration of murmur = correlates to severity of MS S2 OS interval = varies inversely with severity of MS

    **Cardiac FindingsUsually normal or slightly enlarged cardio-thoracic ratioStraightening of left heart borderConvexity of left heart border 2 to enlarged atrial appendage--only in rheumatic heart disease Small aortic knob from decreased cardiac outputDouble density of left atrial enlargementRarely, right atrial enlargement from tricuspid insufficiency

    **The information given was not enough to diagnose the underlying etiology.. If it is based on statistics, the etiology would be Rheumatic Fever. The patients mother also had a heart disease and died early indicating that the patient might have this congenital predisposed to have rheumatic fever. Test should lse be done to prove that it is cause by rheumatic fever or disease. These test are the following: Antistreptolysin O Antibodies, C-Reactive Protien, Sedimentary Rate. Congenital Mitral stenosis can also be considered but the patient should manifest the symptoms on earlier age. **
