三尖瓣無法完全閉合，導致收縮期血流逆流至右心房，引起右心擴張及體循環鬱血。常伴隨肺動脈高壓或僧帽瓣疾病。
Restrictive cardiomyopathy and unclassified cardiomyopathy are also common in cats. Pleural effusion (modified transudate) is more common than pulmonary edema in feline CHF. Clopidogrel is recommended for ATE prevention in cats with moderate-to-severe cardiac disease.
常繼發於僧帽瓣疾病或肺動脈高壓

建議：限制輸液速率 (restricted rate)，避免容量過負荷
監測頻率：居家每日；回診時

需住院密切監控，若不治療可能發展為危及生命 (requires hospitalization and close monitoring)

用藥指引
⚠ 警訊症狀（立即回診）
環境調整
長期計畫：每 3-6 個月心臟超音波追蹤，終身用藥管理
限制活動
限制劇烈運動，允許短距離緩步散步 (leash walk for toileting)
期間：穩定後可漸進恢復，依心功能分級調整
取決於原發病因及嚴重度；繼發性三尖瓣閉鎖不全預後與原發疾病一致；晚期右心衰竭預後不良

詳細問診包括發病經過、用藥史、飲食與環境
CBC、生化全套、尿液分析
