P1792Delirium after transcatheter aortic valve implantation (TAVI) under general anaesthesia: incidence, predictors and relation to long-term survival

Background

Patients undergoing Transcatheter Aortic Valve Implantation (TAVI) are at risk of postoperative delirium (POD). Prospectively collected data on delirium after TAVI are scarce.

Purpose

Aim of this study is to report the incidence and risk factors of POD after TAVI under general anaesthesia. Also we assessed the relation of POD with clinical outcome and short- and long-term survival.

Methods

POD was assessed prospectively in all consecutive patients treated with TAVI in our centre between 2008 and 2017, according to the Diagnostic and Statistical Manual of Mental Disorder (DSM)-IV criteria. TAVI was performed under general anaesthesia in all patients. Outcome was reported according to the updated VARC2-criteria. Survival status was checked by consulting the Municipal Civil Registries.

Results

POD was observed in 16.5% (116/703) of all patients. Stroke and new onset of atrial fibrillation were more often observed in patients with POD (6.9% vs. 1.9%, p=0.007 and 12.1% vs. 5.1%, p=0.005, respectively). Independent preoperative predictors of POD were prior delirium (OR 2.56 [95% CI: 1.52–4.31], p<0.001), aortic valve area (AVA)<0.75 cm2 (OR 2.39 [1.53–3.74], p<0.001), age (1.08 [1.04–1.12], p<0.001) and BMI (0.94 [0.90–0.99], p=0.018). POD was the strongest independent predictor of long-term mortality (HR 1.91 [1.36–2.70], p<0.001) and was associated with impaired 30-day survival (92.2% vs. 96.8%, p=0.034) as well as 5-year survival (40.0% vs. 50.0%, p<0.001).

Survival: Delirium vs No Delirium

Conclusion

One-in-six patients suffered from POD after TAVI under general anaesthesia. Prior delirium and more calcified aortic valve were the strongest independent predictors of POD. POD was the strongest predictor of long-term mortality and was associated with impaired short- as well as long-term survival.

Acute myocardial infarction due to an acute type A aortic dissection involving the left main coronary artery

We report a case of anterior myocardial infarction due to a Stanford type A aortic dissection involving the left main trunk of the coronary artery. Acute myocardial infarction due to extension of an acute Stanford type A aortic dissection is an infrequent but devastating situation. In our case a spontaneous aortocoronary dissection involving the Valsalva sinus and the ascending aorta with a history of hypertension is the most plausible cause. Emergent aortic replacement and revascularisation was performed. (Neth Heart J 2007;15:263-4.).

Outcome and quality of life one year after percutaneous coronary interventions in octogenarians

BACKGROUND

While percutaneous coronary intervention (PCI) is increasingly being performed in octogenarians, little is known about the quality of life (QOL) one year after PCI. We assessed the one-year outcome and QOL after PCI.

METHODS

Outcome and QOL at one year were assessed in patients of 80 years and older who underwent PCI at our institution. We used the RAND-36 Health Survey to assess health-related QOL at follow-up. The EuroSCORE was used for reference risk assessment.

RESULTS

Ninety-eight patients (mean age 82.7+/-2.9 years; 60% female) underwent PCI. Acute PCI was performed in 36% of the patients. Canadian Cardiovascular Society (CCS) angina class before the procedure was class III for 28% and class IV for 64%. Of the patients, 98% were in the highest-risk group (additive EuroSCORE 6+). The overall PCI success rate was 94%. Mortality at one year was 19% (38% acute vs. 12% elective PCI). At followup, general health was rated as fairly good and better then before PCI (CCS I and II: 77%). RAND-36 scores for the mental component were better than scores for the physical component. Physical functioning (41+/-28) and role limitations caused by physical health problems (32+/-37) had the worst scores. The mental component vitality had the lowest (55+/-20) and mental health the highest (70+/-21) score. Social functioning was in general good (67+/-26).

CONCLUSION

Octogenarians have a high mortality risk following PCI, especially in acute PCI. In survivors QOL is acceptable with a better mental than physical score. In general, PCI in octogenarians has a positive effect on health perception, with less symptoms of angina pectoris. (Neth Heart J 2008;16:117-22.).

[Percutaneous closure of a perimembraneous ventricular septal defect: the first 4 patients in The Netherlands]

In four female patients, aged 30, 10, 8 and 2 years and 9 months (the latter with Down's syndrome), all with a perimembranous ventricular septal defect (VSD), percutaneous closure of the VSD was carried out using an Amplatzer endoprosthesis. These were the first 4 patients to undergo this procedure in The Netherlands. In 3 of the patients the procedure was without complications and complete occlusion of the defects was achieved. The last patient developed a left anterior hemiblock after implantation of the device and one week later an intermittent second degree atrioventricular block was detected, for which a pacemaker was implanted. A few days later the atrioventricular conduction time returned to normal. There was complete occlusion of the defect. Percutaneous closure of a perimembranous VSD using an Amplatzer prosthesis is a promising technique with good short-term results. In a selected group of patients this new technique can replace surgical treatment.

A 51-year-old man with palpitations had fast, broad and irregular QRS complexes on his ECG, due to atrial fibrillation and Wolff-Parkinson-White syndrome.

Symptomatic congenital complete absence of the left pericardium. Case report and review of the literature

A fully documented case of complete absence of the left pericardium in a 44-year-old male is presented. Complaints of acute chest pain were caused by strangulation of the heart between the pulmonary ligament and the diaphragm. Preoperative electrocardiogram, chest X-ray and echocardiography showed 'classic' signs as described in the literature. A CAT scan suggested absence of the left pericardium, the definitive diagnosis was made with the aid of thoracoscopy. This case of total absence of the left pericardium is the first documented one requiring thoracic surgery. The defect was closed through a left-lateral thoracotomy using an allograft of pig pericardium.
