Current Clinical Evidence on Rapid Deployment Aortic Valve Replacement: Sutureless Aortic Bioprostheses

Area of Science:

• Cardiology
• Cardiac Surgery
• Geriatrics

Background:

• Aortic stenosis is the most prevalent valvular heart disease in Western populations, primarily affecting individuals aged 65 and older due to age-related degeneration and calcification.
• Untreated symptomatic aortic stenosis carries a poor prognosis, with an average survival of 2 years and a 50% mortality rate within 2-3 years of symptom onset.
• Demographic shifts show an increasing number of elderly patients, particularly those over 80, requiring aortic valve replacement (AVR).

Purpose of the Study:

• To review the current landscape of aortic stenosis treatment, focusing on surgical aortic valve replacement (AVR).
• To highlight recent technological advancements in AVR, including transcatheter and rapid deployment techniques.
• To discuss the expanding indications for AVR in older and high-risk patient populations.

Main Methods:

• Review of current literature and clinical data on aortic stenosis prevalence, prognosis, and treatment outcomes.
• Analysis of trends in patient demographics and surgical interventions from databases like the Society of Thoracic Surgeons (STS).
• Discussion of emerging prosthetic valve technologies and surgical innovations.

Main Results:

• Surgical AVR remains the gold standard for treating aortic stenosis, significantly improving survival and quality of life.
• The proportion of patients over 80 undergoing AVR has doubled in the last two decades.
• The incidence of patients requiring AVR with concomitant coronary bypass surgery has increased fivefold.
• Transcatheter AVR has broadened treatment options to previously inoperable, high-risk patients.
• Rapid deployment AVR offers a novel surgical approach.

Conclusions:

• Aortic stenosis management is evolving, with increasing numbers of elderly and complex patients undergoing AVR.
• Technological advancements, including transcatheter and rapid deployment AVR, are expanding treatment accessibility and efficacy.
• Surgical AVR continues to be a vital intervention for improving outcomes in patients with aortic stenosis.
