A 65-year-old woman was admitted to our institution for recurrent episodes of right heart failure. She reported previous history of ischemic heart disease, chronic kidney disease, and paroxysmal atrial fibrillation (CHA2DS2-VASc score, 4) with bleeding events on vitamin K antagonist and novel oral anticoagulants (HAS-BLED score, 5).
Transthoracic and transesophageal echocardiogram (TEE) revealed a severe tricuspid regurgitation (TR) due to annular dilation. The right ventricle was moderately dilated with normal right systolic function (Figure 2A).
Due to high surgical risk, the patient was scheduled for percutaneous treatment of TR and simultaneous left atrial appendage (LAA) closure.
The procedure was performed under general anesthesia and TEE monitoring. First, transseptal access was performed without complications. After assessing the left atrial appendage (LAA) size and morphology, a 21 mm Watchman device (Boston Scientific) was deployed with successful LAA occlusion (Figures 1A-1D). Subsequently, the Watchman sheath was pulled to the right atrium and exchanged for a MitraClip XTR guiding catheter (Abbott Vascular). After careful imaging of the tricuspid valve and the origin of the regurgitant jet, an XTR clip was deployed between the anterior and septal leaflets close to the center of the valve with reduction of the TR from severe to mild (Figures 2A-2D).
LAA closure and MitraClip implantation in the tricuspid position in the same procedure is a feasible and safe option in patients with a high surgical risk suffering from severe symptomatic TR and bleeding complications under anticoagulant therapy.
