Vascular complications after percutaneous coronary intervention following hemostasis with the Mynx vascular closure device versus the AngioSeal vascular closure device.

Unlabelled: We investigated the prevalence of vascular complications after PCI following hemostasis in 190 patients (67% men and 33% women, mean age 64 years) treated with the AngioSeal vascular closure device (St. Jude Medical, Austin, Texas) versus 238 patients (67% men and 33% women, mean age 64 years) treated with the Mynx vascular closure device (AccessClosure, Mountain View, California).

Results: Death, myocardial infarction or stroke occurred in none of the 190 patients (0%) treated with the AngioSeal versus none of 238 patients (0%) treated with the Mynx.

Novel C-C bond cleavage under mild, neutral conditions: conversion of electron-deficient aryl alkyl ketones to aryl carboxylic esters.

A novel, unique way to cleave the carbon-carbon bond in aryl alkyl ketones under mild, neutral conditions is described. Treatment of aryl alkyl ketones in a refluxing mixture of N,N-dimethylformamide dimethyl acetal and methanol for 16 h provided aryl carboxylic esters. The scope and limitations of the reaction are discussed.
