New rechristened rectangular Amplatzer PVL plug for transcatheter closure
In a recent study published in IHJ researchers tried a Single-center experience of transcatheter closure of mitral and aortic Paravalvular leaks using the new rechristened rectangular Amplatzer PVL plug.
Among 79 transcatheter PVL closures in 8 years, 16 patients received Amplatzer PVL plug. Crescentic shape on three-dimensional echocardiogram was the inclusion criterion. Exclusion criteria was (i) long-axis dimension of PVL exceeding 12 mm; (ii) non-availability of appropriate sized plug in shelf.
In crescentic leaks, Amplatzer PVL plug varying from 8-4 mm to 14-5 mm was preferred. The plug was chosen 1.2–2 times larger than the PVL and the device auto-oriented to the leak. The small 2 mm rim avoided mechanical interference.
Data collection included symptom class, cardiac rhythm, surgical details, type of prosthesis, ventricular ejection fraction, grade of pulmonary hypertension, blood tests for hemolysis and renal function. Residual PVL and valve function were evaluated on echocardiography on 1,6 and 12-month follow-up.
