Results of Valvulotomy for Valvular Pulmonary Stenosis with Intact Ventricular Septum

Abstract

The analysis deals primarily with follow-up studies of patients who have had a valvulotomy for valvular pulmonic stenosis with an intact ventricular septum. In addition to observations on the subjective improvement, hemograms, and arterial oxygen saturation, the cardiac findings have been analyzed in detail. The changes in the size of the heart have been studied in relation to the growth of the patient and, wherever possible, these changes have been correlated with

Pulmonary valve stenosis without ventricular septal defect: results of surgery.

“…The latter figure included the first cases to be operated upon in the world, and if these early severe cases were excluded his mortality would be 7%, a figure similar to the 8% of 86 cases from Johns Hopkins (Hosier, Pitts, and Taussig, 1956) (Table IV). (Brock, 1961;Hosier et al. 1956) ..…”

“…The closed transventricular approach, in which the valvotome and dilator were passed through the apex of the beating right ventricle, has been largely superseded, but not because of its immediate risk, which varies from zero in smaller groups of cases (Humphreys, Powers, Fitzpatrick, and Lanman, 1954;Gadboys, Kyle, and Glover, 1959;Dilley, Longmire, and Maloney, 1963) to the 12% of Brock's large series (Brock, 1961). The latter figure included the first cases to be operated upon in the world, and if these early severe cases were excluded his mortality would be 7%, a figure similar to the 8% of 86 cases from Johns Hopkins (Hosier, Pitts, and Taussig, 1956) (Table IV). (Brock, 1961;Hosier et al.…”

“…Campbell (1959) reported the incidence of subsequent incompetence to be 11 %, although other writers reported it after 20 to 40% of operations (Hosier et al, 1956;Hanson, Ikkos, Crafoord, and Ovenfors, 1958) ./ Closed (Hosier et al, 1956) 69 22 0 (Campbell, 1959) 64 11 5…”

Diseases of the Cardiovascular System (Surgery)

“…The transventricular pulmonary valvulotomy described by Brock (141) and by Sellors (142) has been almost universally adopted as the method of choice in the treatment of these cases. (148) have summarized the experience in our own clinic in the surgical treatment of 78 patients with valvular pulmonic stenosis with intact ventricular septum. The operative mortality was about 8 per cent.…”

Results of Surgery for Congenital Pulmonary Stenosis
