cardiology

Question 1

Fetal ECHO detection of disease

Answer 1

A fetal echo can diagnose CHD now as early as 16 to 18 weeks’ gestation, and as early as 10 weeks’ gestation if done via high-frequency transvaginal echocardiography.

It can also diagnose arrhythmias and hemodynamic changes to the fetal heart.

Question 2

Antibiotic prophylaxis for prosthetic cardiac valve

Answer 2

Any patient with a prosthetic cardiac valve or prosthetic material used for cardiac valve repair should receive antibiotic prophylaxis prior to any dental procedures. Oral amoxicillin in a single dose 30-60 minutes before the scheduled procedure is the first-line agent for antibiotic prophylaxis.
