Heart disease and pregnancy - Influence of pregnancy on heart disease

Accidents occur due to decompensation of injuries (most commonly mitral rheumatic) and adaptive changes imposed by pregnancy. Between injuries, generally well tolerated during pregnancy, include: aortic insufficiency, communications interauriculare, pulmonary artery stenosis, congenital branch block. The prognosis is less favorable: the combination of aortic and mitral lesions, interventricular communications, cardiopathy with right-left shunt (Fallot tetrad).
 American College of Obstetricians and Gynecologists cardiopatele classified in three groups, depending on the risk surrounding the following conditions:1: atrial septal defect, ventricular septal defect, ductus arteriosus, mitral stenosis (gr. I and II) with 0-1% mortality2: mitral stenosis (gr. III and IV), aortic stenosis, aortic coarctation (without valvular disease), tetralogy of Fallot, artificial valve - 5-15% mortality3: pulmonary hypertension, aortic coarctation (valvular), Marfan syndrome, congenital heart - 25-50% mortality.
 Lately, a decrease was observed in rheumatic heart disease and increased association with congenital heart disease. Accidents occur frequently gravido-heart in the second half of pregnancy (according to other opinions in the months III-IV) but the most formidable and lehuzia periods are born.
 Gravido-cardiac accidents can be minor (effort dyspnea, palpitations) or severe decompensation, arrhythmias, peripheral disorders. Most common are cardiac decompensation (pulmonary edema). Fromele acute (intense dyspnea, frothy sputum) are rare, often being sub-events: supine dyspnea, cough, sputum (sometimes bloody), rapid pulse.
 Global Heart failure is rare, may occur at any stage of pregnancy, especially postpartum (intense dyspnea, cyanosis, cough and expectoration asnguinolenta, tachycardia, arrhythmia, hypotension, hepaomegalie, collapse and often death).
 Can be seen various forms of rhythm disturbances, extrasitole, paroxysmal tachycardia or permanent arrhythmia, often preceding or cerebral vascular accident, bundle branch block. Cerebral arterial embolism or limb injuries are serious. Bacterial Endoacrdita always apparent, more common in breaks, birth and puerperium.
