ABSTRACT
OBJECTIVES:
To evaluate the impact of left ventricular (LV) chamber size on procedural and hospital outcomes of patients undergoing aortic valvuloplasty.BACKGROUND:
Balloon aortic valvuloplasty (BAV) is used as an integral step during transcatheter aortic valve implantation. Patients with small, thickened ventricles are thought to have more complications during and following BAV.METHODS:
Retrospective study of consecutive patients with severe, symptomatic calcific aortic stenosis who underwent retrograde BAV at Massachusetts General Hospital. We compared patients with left ventricular end-diastolic diameters (LVEDD) <4.0 cm (n = 31) to those with LVEDD ≥4.0 cm (n = 78). Baseline and procedural characteristics as well as clinical outcomes were compared. Multivariate logistic regression was used for the adjusted analysis.RESULTS:
Patients with smaller LV chamber size were mostly women (80.7% vs. 19.4%, P < 0.01) and had a smaller body surface area (BSA), (1.61 ± 0.20 m(2) vs. 1.79 ± 0.25 m(2) , P < 0.01). Patients with smaller LV chamber size had higher ejection fractions and thicker ventricles. Otherwise, baseline characteristics were similar. The intraprocedural composite of death, cardiopulmonary arrest, intubation, hemodynamic collapse, and tamponade was higher for patients with LVEDD < 4.0 cm (32.3% v. 11.5%, P = 0.01). Adjusting for age, gender, BSA, LV pressure, and New York Heart Association class, LVEDD < 4.0 cm remained an independent predictor of procedural (OR 5.1, 95% CI 1.4-18.2) and in-hospital complications (OR 3.8, 95% CI 1.2-11.6).CONCLUSIONS:
Compared to patients undergoing BAV with LVEDD ≥4.0 cm, those with smaller LV chambers had worse procedural and in-hospital outcomes.
