Utilization of ultrasonic aspirator for combined aortic and mitral valve decalcification: a case study.

Mitral and aortic annular calcification is an age-related degenerative process that can result in severe mitral and/or aortic stenosis and/or regurgitation. Annular calcification not only increases the surgical complexity but also increases the risk of complications. In this case report, we present the innovative use of the Sonopet ultrasonic surgical aspirator for aortic and mitral annular decalcification in a patient with hypertrophic obstructive cardiomyopathy, mild aortic stenosis and moderate mitral regurgitation in the presence of mitral annular calcification (MAC) and aorto-mitral curtain calcification.

Aim: To measure the optimal anterior chamber pressure (ACP) for safe phacoemulsification using a new tube chamber system with internal pressure measurement function in the porcine eye.
Methods: The 20-gauge and 21-gauge straight tips with yellow and orange sleeves, respectively, were covered by a test chamber combined with a pressure sensor for measuring ACP. This was measured for 20s from 10s after starting aspiration in the linear mode using vacuum levels of 200 and 150 mm Hg with a 20-gauge tip, and 300 and 250 mm Hg with a 21-gauge tip.

Transaortic endarterectomy (TE) is an effective and durable method of restoring patency in the aorta afflicted with atherosclerotic disease, which most commonly affects the infrarenal aorta and common iliac artery. When the suprarenal aorta is involved, the disease is usually confined to the orifices of the visceral vessels without obstruction of the aortic lumen. In rare cases, dense, calcified, exophytic, and amorphous lesions causing severe luminal obstruction, termed coral reef atherosclerosis (CRA) of the suprarenal aorta, may occur.

Background: Resection of calcified meningiomas in the ventral thoracic spinal canal remains a formidable surgical challenge despite advances in technology and refined microsurgical techniques. These tumors, which account for a small percentage of spinal meningiomas, are characterized by their hardness, complicating safe resection and often resulting in worse outcomes than their noncalcified counterparts.
Observations: The authors present the case of a 68-year-old woman with a ventrally located ossified meningioma at the T9-10 level, successfully treated via a posterolateral transpedicular approach.
