| Quality of life (score) | Score computed with the "MacNew Heart Disease health-related quality of life instrument".The MacNew is a valuable tool for assessing and evaluating health related quality of life in heart disease patients. It consists of 27 questions, falling into 3 possible domains: physicial limitation capacity (13 questions), emotional domain (14 questions), social domain (13 questions), symptom related (5 questions). The time frame for the MacNew is the previous two weeks. Scoring of the MacNew is simple: one score in each domain and a global score (4 scores). The maximum possible score in any domain is 7 [high HRQL] and the minimum is 1 [poor HRQL].The global score is calculated as the average over all scored items unless one of the domains is completely missing. | Evaluated once by means of a phone contact performed in 2016, irrespective of the date the surgery was performed |
| Survival rate | Survival rate | Evaluated once by means of a phone contact performed in 2016, irrespective of the date the surgery was performed |
