Indications
- severe aortic valvular stenosis
- severe aortic insufficiency
- endocarditis not reponsive to medical therapy
Procedure
- mechanical valve vs bioprosthetic valve
- choice of valve for patients age 55-70 years is not clearcut & should be based on patient preferences[4]
- mortality benefit for mechanical valve vs bioprosthetic valve persists until age 55 years[21]
- percutaneous transcatheter aortic valve replacement (TAVR) may be alternative to surgery[3][5]
- no difference between TAVR & open surgery in death, stroke, or MI at 1 year in patients at low surgical risk[10]
- perioperative beta-blockade reduces incidence of postoperative atrial fibrillation[18]
- cardiac rehabilitation beneficial after cardiac valve surgery[26]
- functional class
- rhythm other than sinus rhythm
- preoperative atrial fibrillation associated with worse long-term outcomes[15]
- postoperative atrial fibrillation associated only with short-term complications[16]
- preoperative left ventricular systolic dysfunction
- aortic regurgitation
- concomitant surgical procedures
- previous bypass surgery
- emergency surgery
- coronary artery disease
- female gender
- concurrent mitral valve surgery
- hypertension
- depression may increase 1 year mortality[22]
Complications
- 4-24% in the elderly
- prosthetic valve degeneration
- structural valve deterioration less frequent after self-expanding TAVR than open surgery (2.2% vs 4.4%)[27]
- transcatheter aortic valve replacement (TAVR) for patients too frail for surgery[7]
- aortic valvular stenosis associated with worse prognosis than aortic insufficiency
- risk of cognitive impairment after CABG, PCI or cardiac valve replacement is uncertain[11]
- risk for thromboembolic events with bioprosthetic valve associated with reduced leaflet motion
- therapeutic warfarin restores leaflet motion in bioprosthetic aortic valve[13]
- risk for atrial fibrillation 14% after TAVR & 31% after surgical aortic valve replacement[25]
- cardiac arrhythmias
- prolonged ventilatory support requirements
- congestive heart failure
- perioperative myocardial infarction (3-8%)
- cerebrovascular events (5-11%)[9][19]
- radiographic evidence of ischemic stroke within 7 days of aortic valve replacement may be as high as 66%[19]
- surgical aortic valve replacement after ischemic stroke increases risk of recurrent stroke, especially within 3 months
- 15-fold within 3 months of ischemic stroke
- 4-fold within 3-12 months
- 2-fold if > 1 year [23]
- prosthesis-patient mismatch, a small surgical aortic valve orifice for a patient's size, is ssociated with increased mortality[24]
Notes
prognosis: long-term survival:
- patients > 80 years
- 1 year 91%
- 3 years 84%
- 5 years 76%
- patients > 90 years
- 1 year 81%
- 2 years 46%[9]
- no survival benefit of one prothetic heart valve type over another[8] *
- symptoms resolve in 43% of patients
- symptoms persist in remaining patients
- dyspnea in 43%
- 14% hospitalized with heart failure
- syncope in 4%
- 2% with angina[28]
- symptoms persist in remaining patients
Left ventricular function improves post-operatively.
Clinical & histological evidence of diastolic dysfunction persists for up to 8 years post-operatively.
Afternoon surgery rather than morning surgery is linked to better outcomes[20]
