I also thank Dr Hartz for her kindness in sending me a copy of the manuscript before the meeting and for inviting me to discuss this report.
Our group has now done a total of more than 700 of these operations and a little more than 500 since 1990. After receiving the manuscript we analyzed 285 patients who had been operated on between April 1993 and December 1995. Nineteen of these patients died, for a total mortality of 6.6%. In the limited time available we were only able to extract complete hemodynamic data for 249 of these patients, and this group had a slightly higher mortality of 7.2%. We then divided this cohort, as you did, into two groups, those with a preoperative PVR greater than 1,100 dynes • s • cm-5 and those with a PVR less than this. Seventy-one patients had a PVR greater than 1,100 dynes • s • cm-5, with a mean of 1,433 dynes • s • cm-5. In this group the mortality was 12.6%, compared with 5% in those with a lower resistance. However, this did not achieve statistical significance. Thus, although I would agree that patients with a higher preoperative PVR tend toward being at greater risk, if the cause is thromboembolic, . . . [Full Text of this Article]
