Ebstein's Disease : A Report of Five Cases

Clinical Study of Twenty-Three Cases of Ebstein's Anomaly of the Tricuspid Valve

“…Iii measuring the blood pressure, the diastolic end point was sometimes difficult to atscertaini, particularly if the patient was cyanotic or ill heart failure. Similar observations have been made by Blacket et al 9 and Kilby et al 13 In general, no specific observations were made regarding the neck veins. There was a definite presystolic pulsation of the neck vessels associated with tricuspid insufficiency in case 7, who was ill severe congestive failure.…”

Ebstein's Syndrome

“…Cardiac catheterization has been performed in nearly half of the cases reported. Serious arrhythmias were common during the procedure and at least six deaths have been reported (Baker et al, 1950;Schaede, 1951;Blacket et al, 1952;Campbell, 1953;.…”

Electrode catheters and the diagnosis of Ebstein's anomaly of the tricuspid valve.

“…Though cardiac catheterization and angiocardiography may be helpful and yield valuable information, in many patients no intracardiac investigations have been carried out because of repeated warnings about the dangers of these procedures in such patients (Baker, Brinton, and Channell, 1950;Engle et al, 1950;Schaede, 1951;Blacket et al, 1952;Campbell, 1953;Kjellberg et al, 1955;Brown, Heath, and Whitaker, 1956;Wood, 1956;Mayer, Nadas, and Ongley, 1957); in addition there is a lack of detailed knowledge about the haemodynamic effects peculiar to this lesion. While there is no doubt that catheterization carries a greater risk in these circumstances, increased experience of investigative techniques in general, plus improved methods of dealing with rapid paroxysmal tachycardia and cardiac arrest, have made it much less hazardous than it used to be.…”
