Abstract
Both pectus excavatum (PE) and the preexcitation syndromes have been shown to be associated with mitral valve prolapse. This study was conducted prospectively to determine the association of preexcitation syndromes in patients with PE. Seventy-six patients under eighteen years of age, mean of five years, with PE, underwent cardiac examination, electrocardiography and echocardiography. Fifty-eight were males and eighteen were females. Thirty-five had a family history of PE. Nineteen had mitral valve prolapse and nine had scoliosis. Eight (11%) had electrocardiographic evidence of preexcitation: Wolff-Parkinson-White type in five, Lown-Ganong-Levine type in three, whereas five had paroxysmal supraventricular tachycardia. In addition, we had preexcitation in 22% of females, 7% of males, 11%/10% of patients with/without a family history of PE, 11%/10% of patients with/without scoliosis, 112/11% of patients with/without mitral valve prolapse, and 10%/11% of patients younger/older than eight years. This study indicates a high association of preexcitation syndrome in patients with PE, especially when female had PE. Its incidence was not particularly higher even in the presence of family history, scoliosis, mitral valve prolapse or in younger pediatric patients.
