CAV3 and pulmonary vascular congestion: Thus, in both WT and Cav‐3 OE mice, TAC resulted in cardiac hypertrophy, indicated by a significant increase in heart weight:tibia length ratio (HW:TL; Figure 1f), and pulmonary congestion, a symptom of congestive heart failure, indicated by a significant increase in lung weight:tibia length ratio (LW:TL; Figure 1g); however, HW:TL following TAC was significantly smaller in Cav‐3 OE than in WT mice (Figure 1f).
