WORKSHOP 12 III-C6 Matematico Matias Maulion Medenilla Medina, K. Medina, S. Mejino Melgarejo Mendoza, A MITRAL VAVLE PROLAPSE
CC: PALPITATION MM 23 years old Female
PHYSICAL EXAMINATION • Conscious, coherent, ambulatory • BP: 110/70 CR 80/min regular RR 16/min • BMI 19 • Symmetrical chest expansion, narrow A-P diameter of the chest, no retractions, clear breath sounds • Adynamicprecordium, AB at 5th LICS MCL, no murmurs, (+) midsystolic click followed by 2/6 midsystoliccresecendo murmur noted at the apex
REVIEW OF SYSTEMS • (-) dizziness • (-) loss of consciousness • (-) cough or colds • (-) PND or Orthopnea
LABORATORY AND ANCILLARY TEST • 2D Echo-Doppler: MVP, anterior mitral valve leaflet with moderate MR, slightly dilated LA with no evidence of thrombus • 123L ECG: sinus rhythm, occasional premature atrial complexes • CXR: Normal
Physical examination • Body weight is often low ; asthenic • Blood pressure is usually normal or low • Orthostatic hypotension • Resting bradycardia • Thoracic skeletal abnormalities suggesting MVP: • Scoliosis, pectus excavatum, straightened thoracic spine, and narrowed AP dm of the chest Zippes, D., et al. (2005) Braunwald’s Heart Disease: A textbook of Cardiovascular Medicine, 7th ed. USA: Elsevier Saunders
Auscultation: • Nonejection systolic click at least 0.14 sec after S1 • Multiple mid and late systolic clicks along the L lower sternal border • Mid to late crescendo systolic murmur that continues to A2 Zippes, D., et al. (2005) Braunwald’s Heart Disease: A textbook of Cardiovascular Medicine, 7th ed. USA: Elsevier Saunders
Dynamic Auscultation: Zippes, D., et al. (2005) Braunwald’s Heart Disease: A textbook of Cardiovascular Medicine, 7th ed. USA: Elsevier Saunders
Dynamic Auscultation: Response of the Murmur of MVP to Interventions Fuster, V.,et al. (2008) . Hurst’s The Heart, 12the ed. China: McGrawHill Co.
Symptoms Common Uncommon TIA Congestive Heart Failure Endocarditis in MR associated with MVP Sudden death • Easy fatigability • Shortness of breath • Palpitation • Chest pain • Light-headedness • Syncope
Symptoms associated with AUTONOMIC DYSFUNCTION are associated with GENETICALLY INHERITED MVP: Atypical chest pain Fatigue Orthostasis Syncope or presyncope Neuropsychiatric symptoms • Anxiety • Panic attacks • Exercise intolerance • Palpitations (may be a symptom of benign arrythmias)
Symptoms Related to progression of Mitral Regurgitation: • Fatigue • Dyspnea • Exercise intolerance • Orthopnea • Paroxysmal nocturnal dyspnea
Long term complications: • Severe Mitral Regurgitation • over years or decades, due to chordal rupture and massive prolapse of both leaflets • rapidly, due to chordal or endocarditis • Arrythmias • most commonly ventricular premature contractions and paroxysmal supraventricular and ventricular tachycardia
Long term complications: • Transient cerebral ischemic attacks • secondary to emboli from the mitral valve due to endothelial disruption have been reported, • Infective endocarditis • may occur in patients with MR and/or leaflet thickening
4. WHAT POPULATION GROUP IS ASSOCIATED WITH AN INCREASED PREDILECTION FOR MVP?
Greater frequency among those with Collagen (type 3) Disorders: • Marfan’s Syndrome • OsteogenesisImperfecta • Ehlers-Danlos Syndrome
