BACKGROUND The composition of a diet can influence myocardial metabolism and development of left ventricular hypertrophy (LVH). The impact of a high-fat diet in chronic left ventricular volume overload (VO) causing eccentric LVH is unknown. This study examined the effects of chronic ingestion of a

In order to assess the sensitivity and specificity of the range-gated pulsed Doppler echocardiogram for the detection of aortic regurgitation, a study with use of this technique was carried out in 46 patients. They were classified into 3 groups: Group I was composed of 19 patients with a variety of

BACKGROUND The appetite-suppressant drug fenfluramine, usually given in combination with phentermine, has been reported to be associated with cardiac valvular regurgitation. Concern has been raised that the d-enantiomer of fenfluramine, dexfenfluramine, may also cause this problem. We were able to

OBJECTIVE Serotonin-releasing agents prescribed as weight-loss medications have been implicated as a cause of acquired aortic and mitral valve abnormalities. Sibutramine hydrochloride (MERIDIA) is a serotonin and norepinephrine reuptake inhibitor with proven efficacy of weight reduction. The purpose

BACKGROUND Second-generation TAVI prostheses may enhance the procedure reducing operative time and complications rate, maintaining adequate valve hemodynamic performance. We present our results with 2 new generation trans-catheter aortic valve (TAVI) prostheses in obese patients. METHODS A series of

Echocardiography is recommended for the detection of valvular regurgitation in asymptomatic users of anorexigens with a heart murmur. To determine the prevalence and diagnostic value of heart murmurs for valvular regurgitation, 223 patients receiving dexfenfluramine therapy for 6.9 months and 189

Bile duct injuries (BDI) tend to be more complex in laparoscopic than in open cholecystectomy procedures, and frequently involve young adults with benign pathologies. The ultimate consequence may be a liver transplantation (LT), making this situation one of the most rare transplant indications.

In 1997, the US Food and Drug Administration (FDA) reported valvular regurgitation (aortic regurgitation [AR] mild or greater and/or mitral regurgitation [MR] moderate or greater) in 32.8% of patients treated with anorexigens. This study sought to determine the natural history of valvular
