Factors Determining In-Hospital or Late Survival after Aortic Valve Replacement: Conclusion

The p value became significant at 8.7 years, in contrast to a previous analysis in which actuarial survival was the same at six years. In addition, there was a significant difference in survival between patients with advanced age or advanced functional class when compared with people younger than 62 years of age or in class […]

Factors Determining In-Hospital or Late Survival after Aortic Valve Replacement: Outcome

Myocardial protection, even with the use of crystalloid cardioplegia, was not complete, as the most common cause of in-hospital mortality was either low’ cardiac output or myocardial infarction. This is particularly true in the initial experiences, when the recently introduced hyperka-lemic crystalloid cardioplegia was used as a single dose, even in those procedures necessitating prolonged […]

Factors Determining In-Hospital or Late Survival after Aortic Valve Replacement: Survival of Valve

Survival of Valve Intrinsic tissue failure compromised function of the bioprosthetic valve in 17 patients (8 percent or 17/224) (70 percent CL = 5.8, 9.9) at 32 to 91 months after implantation in patients 23 to 77 years of age (mean, 54.6 years) at the time of implantation. Actuarial surv ival from intrinsic valve tissue […]

Factors Determining In-Hospital or Late Survival after Aortic Valve Replacement: Late Mortality

Actuarial survival of patients, including in-hospital mortality, when plotted, depicted a significantly better survival at 8.7 years for patients who had undergone isolated AVR than those who had a concomitant procedure (p^O.OOl) (Fig 3). Moreover, even when patients with isolated AVR were compared with those whose concomitant procedure was solely one to three concomitant coronary […]

Factors Determining In-Hospital or Late Survival after Aortic Valve Replacement: Results

Causes of in-hospital mortality have been tabulated (Table 1). Univariate logistic regression analysis identified age over 60 years (p = 0.015) and advanced preoperative NYHA functional class (3 and 4) (p = 0.003) as incremental risk factors affecting inhospital survival. Incremental risk factors by multivariate analysis were age over 60 years (p = 0.038), advanced […]

Factors Determining In-Hospital or Late Survival after Aortic Valve Replacement: Collection of Data and Statistical Analyses

Collection of Data and Statistical Analyses Preliminary data on all patients was gathered retrospectively from patients’ hospital records and questioning patients. The condition of patients has been ascertained yearly since 1981. This was accomplished by examination of the patient by the cardiologist or cardiac surgeon (or both) and by telephone interview with the patient or […]

Factors Determining In-Hospital or Late Survival after Aortic Valve Replacement

To determine factors affecting in-hospital or late survival of patients following AVR, a retrospective analysis was undertaken in a group of patients undergoing AVR with a single type of valve substitute. The findings are the basis of this presentation. Demography Two hundred and forty patients underwent AVR between February 1977 and December 1983. There were […]
