What are the special heart disease during pregnancy phenomenon

Heart disease during pregnancy can be divided into two categories. The first category is the pre-existing heart disease, rheumatic and congenital heart disease to the majority, hypertension, heart disease, mitral valve prolapse, and hypertrophic heart disease rare. The second category of the pregnancy-induced heart disease, heart disease such as pregnancy-induced hypertension, heart disease perinatal period.

1. Heart failure: heart disease patients with cardiac function if the original has been damaged or barely compensated, because of pregnancy and further heart failure compensation. Rheumatic heart disease in pregnant women, for heart failure performance: ① lung disposable blood: more common in mitral valve disease, patients with short breath, even after the exertion, Liang Fei at the bottom of a small wet-Music. X-ray examination showed interstitial edema. ② acute pulmonary edema: more common in severe mitral stenosis, due to high blood volume caused by pulmonary hypertension. Patients with sudden short breath, not sits flat, cough, sputum, or 1,10 bubble-like blood, scattered Asthma Liang Fei Ming-or wet-Music. ③ right heart failure: common in older, more notable expansion of the heart, atrial fibrillation, which are usually labor diminish, or had heart failure in the history of the Treasury. Prior heart disease pregnant women, patent ductus arteriosus, atrial septal defect, such as ventricular septal defect with pulmonary hypertension, often leads to right heart failure, pulmonary stenosis and tetralogy of Fallot, the right ventricular pressure overload, and more Performance for the right heart failure; aortic stenosis may be due to overloading and left ventricular pressure table to the left heart failure.

2. Infective endocarditis: Regardless of rheumatic heart disease or congenital heart disease can be complicated because of bacteremia and infective endocarditis. If not timely controlled can trigger heart failure and death.

3. Hypoxia and cyanosis: in the cyanotic congenital heart disease, which usually have hypoxia and cyanosis, pregnancy, low-resistance, cyanosis increase. Non-cyanotic type, left to right shunt congenital heart disease pregnant women, because of blood loss and blood pressure dropped and other reasons, can be caused by a temporary reverse triage, right-to-left shunt, which caused cyanosis and hypoxia.

4. Embolization: during pregnancy, blood in a hypercoagulable state, coupled with heart disease increased with the vein and the vein blood pressure Yuzhi, easy with Embolism. Thrombosis likely to come from the pelvis, cause pulmonary embolism, increased pressure on the pulmonary circulation, thereby stimulating pulmonary edema, or left to right shunt reversed for right-to-left shunt. If the cavity around the traffic congenital heart disease, thrombosis may be caused by defects around the artery embolization.
