RESUMEN
Aortic valve endocarditis can lead to secondary involvement of aorto-mitral curtain and the adjacent anterior mitral leaflet (AML). The secondary damage to AML is often caused by the infected jet of aortic regurgitation hitting the ventricular surface of the mitral leaflet, or by the pronounced bacterial vegetation that prolapses from the aortic valve into the left ventricular outflow tract. This is called 'kissing lesion'. We describe a patient with infective endocarditis of the aortic valve causing perforation of both noncoronary cusp of aortic valve and the AML, which is rare.

A middle-aged female patient, previously diagnosed with asthma, presented with a large spontaneous left pneumothorax. She had a history of nephrectomy for a ruptured renal angiomyolipoma (AML) with a postoperative spontaneous pneumothorax when she was an adolescent. High-resolution CT chest revealed multiple scattered thin-walled lung parenchyma cysts consistent with lymphangioleiomyomatosis (LAM). Hepatic AMLs and adenoma sebaceum skin lesions were also noted, consistent with an overall diagnosis of tuberous sclerosis. Her acute management included lung re-expansion via chest tube insertion, antibiotics for concurrent chest infection, nebulisation and chest physiotherapy. Since discharge, the patient had only occasional shortness of breath, relieved by bronchodilators. She is considering expanded immunisation as well as enrolment in a clinical trial. Her hepatic AMLs will be monitored via ultrasound for growth. LAM treatment is generally aimed at its complications with lung transplantation reserved for severe disease; however, hormonal therapy and the mTOR inhibitor aim at targeting systemic disease.
