Major Aortopulmonary Collateral Arteries and Their Effects on Perioperative Parameters and Mortality of Children with Tetralogy of Fallot: A Case-control Study.
Iran J Med Sci
December 2024
Neonatology Research Center, School of Medicine, Shiraz University of Medical Sciences, Shiraz, Iran.
Background: Inadequate pulmonary blood flow in tetralogy of Fallot (TOF) can lead to the development of major aortopulmonary collateral arteries (MAPCA), which interferes with surgical repair. The present study evaluated the features of MAPCAs among patients with TOF and their treatment approaches. Besides, perioperative parameters and mortality rates of our TOF patients with and without MAPCA were compared.

Percutaneous biopsy is the standard of care for breast lesions, except nipple lesions which are primarily biopsied by excision due to perceived risks of pain and bleeding. However, excisional biopsy of nipple lesion inevitably leads to disfigurement and possible loss of the nipple-areolar complex (NAC), highlighting the need for minimally invasive biopsy techniques. We present our experience of seven patients who underwent ultrasound-guided core biopsy or vacuum-assisted biopsy (VAB) for sampling of clinically occult nipple lesions.

Background: Treatment of residual mitral regurgitation (MR) with different percutaneous devices after transcatheter edge-to-edge repair (TEER) has been reported as an alternative option to reclipping or surgery. This review aims at describing the different transcatheter strategies available and their results when managing residual MR after TEER.
Methods: A literature search was undertaken across Pubmed, ScienceDirect, SciELO, DOAJ, and Cochrane library databases, to identify article reporting patients with post-TEER residual MR managed by a transcatheter approach that did not involve only the implantation of new clips.
Although the long-term outcomes of the surgical grafts are well defined and reported, the data regarding the mid-and long-term results of the balloon-expandable percutaneous valves in the native right ventricular outflow tract (RVOT) is limited. We retrospectively evaluated 42 patients who underwent PPVI (Sapien® XT valve) to native RVOT due to severe pulmonary regurgitation (PR) and/or moderate to severe pulmonary stenosis (PS) between August 2015 and November 2020. The median patient age at the time of PPVI was 13.

Mount Sinai Health System, New York, NY.
Objective: The aim of this study was to assess the effectiveness of non-invasive coronary computed tomography angiography (CTA) as an alternative to traditional invasive coronary angiography (ICA) for preoperative evaluation of low risk patients with an indication for non-emergent mitral surgery and to assess any difference in adverse outcomes from this strategy.
Methods: This was a retrospective cohort study from a single center with data collected from July 2014 - June 2020 for 1576 patients undergoing mitral valve surgery of all etiologies - excluding patients requiring coronary artery bypass surgery. We performed a 1:2 propensity score matching for patients evaluated with CT (n=345) to those evaluated with ICA (n=602).
