A 46-year-old man presented with a complaint of effort dyspnea. On transthoracic echocardiography a circle appeared in LVOT. It was seen freely floating, disappearing in every systole and appearing again in diastole. Turbulence was seen inside the circle with color Doppler. Transesophageal echocardiography showed aortic cusps and their coaptation to be normal. Aortic root diameters were normal at the annulus, sinus of Valsalva, and sinotubular junction. There were no signs of dissection, infective endocarditis or abscess. But as the probe was advanced, left sinus of Valsalva was found to be prolapsed, and ruptured into LVOT.

The effect of malnutrition on outcomes after carotid artery stenting (CAS) is not well known. This study reports the relationship between malnutrition and post-procedure 30-day major adverse events (MAEs). A total of 978 patients hospitalized for CAS were enrolled in the study. Controlling nutritional status (CONUT) score, the nutritional risk index (NRI), and the prognostic nutritional index (PNI) were calculated. MAEs (myocardial infarction, stroke/transient ischemic attack and mortality) were compared. According to the CONUT score, NRI, and PNI, 9.4%, 41%, and 11.4% patients were moderately or severely malnourished, respectively; 74.8% were at least mildly malnourished by at least 1 score. Forty-seven patients (4.8%) had a post-procedure 30-day MAE. Continuous classifications of the indexes were independently associated with higher MAE. CONUT showed the highest predictive ability, whereas NRI had the lowest (C-index: CONUT, 0.701; NRI, 0.681; PNI, 0.688). According to categorical classification of indexes, only CONUT and PNI showed predictive ability for MAE. Malnutrition assessment could identify patients with CAS at elevated risk for MAE. CONUT, NRI, and PNI continuous scores were independent prognostic factors for the post-procedure 30-day MAE. According to our study, CONUT showed the highest predictive ability.
