Durability, Haemodynamic Performance, and Clinical Outcomes of the Carpentier Edwards PERIMOUNT Valve in the Indian Population

Key Result

The Carpentier Edwards PERIMOUNT valve demonstrated an estimated 5-year survival of 92.9% and a low structural valve deterioration rate of 2.38% following aortic valve replacement.

Study Design

Type

Observational (n=42)

Multicenter

Structured PICO

Population

42 adults (aged ≥18 years) undergoing aortic valve replacement (AVR) for aortic valve disease (85.72% aortic stenosis), mean age 67.42, 76.19% male, Indian cohort.

Intervention

Aortic valve replacement (AVR) with the bovine pericardial bio-prosthesis (Carpentier-Edwards PERIMOUNT, Model 2800TFX)

Outcome

Mortality and Major Adverse Cardiac and Cerebrovascular Events (MACCE), defined as readmission for heart failure, thromboembolism, infective endocarditis, or structural valve deterioration (SVD) at 5 yearscomposite

The Carpentier Edwards PERIMOUNT valve demonstrates excellent 5-year survival, sustained haemodynamic performance, and low rates of structural valve deterioration in an Indian population.

Limitations

Retrospective design carries a risk of selection bias and limits the ability to establish causal relationships.
Relatively small sample size reduces statistical power and may limit the generalisability of the results.
Follow-up duration of 5 years is relatively short for the assessment of structural valve deterioration.
Predominance of smaller valve sizes (19 mm) may have influenced the observed haemodynamic outcomes.
Low number of events limits the statistical power of survival analysis.

Abstract

Background: The Carpentier Edwards PERIMOUNT valve is widely used for aortic valve replacement (AVR) due to its favourable haemodynamic profile and durability. This study evaluated durability, haemodynamic performance, survival, and clinical outcomes following AVR using this valve. Methods: This single-centre retrospective observational study included 42 patients who underwent AVR with the Carpentier Edwards PERIMOUNT valve between January 2016 to December 2016. Ethical approval was obtained prior to study initiation. Patients were followed at mid-term (6-months) and long-term (5-years). Clinical status was assessed using New York Heart Association (NYHA) functional class, and echocardiographic parameters included effective orifice area (EOA), peak pressure gradient (PPG), mean pressure gradient (MPG), peak systolic velocity (PSV), and left ventricular ejection fraction (LVEF). Survival analysis was performed using the KaplanMeier method. Results: The mean age was 67.426.51 years, and 76.19 of patients were male. Calcificdegenerative aortic valve disease was the most common aetiology (59.52). Preoperatively, patients had severe valvular obstruction with a mean EOA of 1.30.6cm² and mean pressure gradient of 54.729.5mmHg. At 5-years, sustained haemodynamic improvement was observed, with EOA of 1.90.6cm² and persistently reduced gradients (PPG 24.05.0 mmHg, MPG 12.82.5 mmHg). Functional status improved significantly, with the majority of patients in NYHA class III during follow-up. Three deaths (7.14) occurred during the follow-up period. KaplanMeier analysis demonstrated an estimated 5-year survival of 92.86. Structural valve deterioration occurred in 2.38, requiring redo AVR. Conclusions: The Carpentier Edwards PERIMOUNT valve demonstrates excellent mid-to long-term survival, sustained haemodynamic performance and significant symptomatic improvement.
