Slide 1-

Heart disease with pregnancy Prof Uma Singh
Slide 2-

Incidence of heart disease Varies between 0.1 – 4.0 %, average 1% Mortality due to heart disease has decreased Devpd countries – maternal mortality due to heart disease has increased Pregnancy with heart disease has increased Devpd countries – rheumatic is decreasing Congenital heart disease with pregnancy is also increasing
Slide 3-

Hemodynamic changes in normal pregnancy
Slide 4-

Critical periods Changes start from as – 6weeks Max changes around –30 weeks Intra partum period Just after delivery Second week of puerperium
Slide 5-

Pregnancy changes mimic cardiac disease Symptoms – breathlessness, weakness, oedema, syncope Tachycardia Splitting of 1st hear sound Murmur – systolic , breast bruit Displacement of apex beat – upwards to left
Slide 6-

Symptoms of heart disease Progressive dyspnea or orthopnea Nocturnal cough Syncope Chest pain Hemoptysis
Slide 7-

Clinical findings of heart disease Cyanosis Clubbing of fingers Persistent neck vein distention Systolic murmur grade 3/6 or greater Diastolic murmur Cardiomegaly Persistent arrythmia Persistent split second sound Pulmonary hypertension
Slide 8-

Investigations ECG – cardiac arrhythmias, hypertrophy Echocardiography – cardiac status and structural anomalies X-ray chest – cardiomegaly, vascular prominence Cardiac catheterization - rarely
Slide 9-

NYHA (New York Heart Association) Functional grading of heart disease Grade I: No limitation of physical activity- asymptomatic with normal activity Grade II: Mild limitation of physical activity -Symptoms with normal physical activity Grade III: Marked limitation of physical activity -Symptoms with less than normal activity, comfortable at rest Grade IV: Severe limitation of physical activity- symptoms at rest
Slide 10-

Classification of Heart Disease according to etiology Congenital – non cynotic ( ASD, VSD, Pulm stenosis, coarctation of aorta), cyanotic (Fallots tetralogy, Eisenmenger’s syndrome) Rheumatic heart disease – MS, MR, AS, AR Cardiomyopathy Ischaemic heart disease Others – conduction defects, syphilitic, thyrotoxic, hypertensive,
Slide 11-

Classification of Heart Disease during pregnancy according to risk Low risk ( 0 – 1%) – ASD, VSD, PDA, MS-1,2, corrected FT Medium risk ( 5 – 15 %) – MS-3,4, MS with atrial fibrillation, AS, uncorrected FT High risk ( 25 – 50%) – PH, Eisenmengers Syndrome, aortic coarctation with valvular involvement, Marfans with aortic involvement
Slide 12-

Poor prognostic indicators h/o heart failure, ischaemic attack, stroke Arrhythmias, Base line NYHA class 3 and 4 MV area below 2cm sq, AV area below 1.5 Ejection fraction less than 40%
Slide 13-

Additional risk factors Anaemia Infections Hypertension Physical labour Weight gain Multiple pregnancy Caffein , alcohol intake Pain Drugs – tocolytic
Slide 14-

Effect of pregnancy on heart disease Worsening of cardiac status CCF, bacterial endocarditis, pulmonary edema, pulmonary embolism, rupture of aneurism No long term effect on basic defect
Slide 15-

Effect of heart disease on pregnancy Abortion Preterm labour IUGR Congenital heart disease in baby – 5% Intrauterine fetal demise
Slide 16-

Management Requires- High index of suspicion Timely diagnosis Effective management Team Approach- Obstetrician Cardiologist Anesthetist Neonatologist CTV surgeon Nursing Staff
Slide 17-

Preconceptional Counseling No pregnancy unless must esp in high risk types Maternal mortality varies directly with functional classification at pregnancy onset Optimal Medical/Surgical treatment pre-pregnancy Counselling- Maternal & Fetal risks Prognosis Social and cost considerations Hospital delivery- Preferable at tertiary care centre
Slide 18-

Medical termination of pregnancy Termination advised in early pregnancy in high risk group only – ( Primary pulmonary Ht, Eisenmenger syndrome, Coarctation of aorta, Marfan syndrome with dilated aortic root) Only in 1st trim, better before 8 weeks Suction evacuation preferred MTP also carries risk for life
Slide 19-

Antenatal care Clear counseling of risk and prognosis ANC every 2 weeks upto 30 weeks then weekly On each visit-note-pulse rate, BP, cough dyspnea, weight, anaemia, auscultate lung bases, re-evaluate functional grade Ensure treatment compliance Exclude fetal congenital anomaly by level-III USG and fetal ECHO at 20 weeks in maternal congenital heart disease Fetal monitoring
Slide 20-

Special Advice Rest, Avoid undue excitement/strain Diet/ Iron and vitamins Hygiene, dental care to prevent any infection Dietary salt restriction (4-6g/d) Avoid smoking, drugs – betamimetics Early diag and tmt of PIH, infections Therapeutic/prophylactic cardiac interventions as applicable- Benzathine Penicillin 12 lacs at 3 weeks - to prevent recurrence of rheumatic fever Diuretics, Beta Blockers, Digitalis, Anticoagulants Surgical treatment as applicable - balloon mitral valvotomy
Slide 21-

Indications for admission Elective admission- NYHA 1 – 2 weeks before EDD NYHA 2 – 28 to 30 weeks NYHA-III/IV- Irrespective of POG as soon as patient comes To Change from oral anticoagulants to heparin-early pregnancy, 36 weeks in patients on anticoagulant Emergency admission- Deterioration of functional grade Symptoms and signs of complications- Fever/ persistent cough/ basal crepts/ tachyarrhythias (P/R >100 min)/ JVP>2cm/Anaemia/ Infections/ PET/Abnormal weight gain /other medical disorders
Slide 22-

Labor and Management Institutional delivery Induction of Labor Only for obstetric indications Oxytocin preferred- Higher concentration with restricted fluid Intracervical foley instillation esp in congenital heart disease PGE2 Gel may be employed- Vasodilatation - use with caution
Slide 23-

Management in first stage of labor Confined to bed- propped up or semi recumbent Intermittent oxygen inhalation 5-6 l/min Sedation and analgesia- (Epidural, pethidine, tramadol) Cautious use of I.V. fluids (not >75ml/hr except in aortic stenosis and VSD) Stop anticoagulants Digitalise if in CHF,P.R.>110/ min, R/R >24/min
Slide 24-

Management in first stage of labor Diuretics in pulmonary congestion Deriphyllin if bronchospasm Prevention of infective endocarditis Cardiac monitoring and pulse oximetry ±pulmonary artery catheterisation- continuous haemodynamic monitoring Evaluation by Anaesthetist and cardiologist
Slide 25-

SABE Prophylaxis
Slide 26-

Management of second stage of labor Delivery in propped up position Avoid forceful bearing down Adequate pain relief-epidural/pudendal block avoid spinal/Saddle block Cut short second stage of labor- episiotomy, vacuum, forceps – not always must Strict Cardiovascular monitoring
Slide 27-

Third stage of labor- AMTSL-10 U oxytocin IMI Avoid bolus syntocinon/Ergometrine Propped Up, oxygen inhalation Furosemide I.V. 40 mg Pethidine/morphine (15mg) Watch for signs of CHF & Pul. Edema Treat PPH energetically
Slide 28-

First Hour After Delivery Propped up/sitting position, oxygen Watch for signs of pulm edema Sedation Antibiotics
Slide 29-

Indications for LSCS- Mainly obstetrical Coarctation of aorta Marfan syndrome with dilated root of aorta Prefer epidural anaesthesia Narcotic conduction analgesia/GA in Pulmonary hypertension and pts having intracardiac shunts
Slide 30-

Advice at time of discharge: Continue medical treatment Avoid infection Reassesment after 6 weeks or earlier if some complication occurs Iron supplementation Cardiological consultation for definitive management of heart disease
Slide 31-

Contraceptive advice at time of discharge: Contraception- Barrier, Progesterone – good option- DMPA, Norplant IUCD-Less preferred COC - contraindicated Sterilization- vasectomy-best Tubal ligation-Interval, puerperial can be done
