Preoperative intraaortic balloon pumping improves the results of complex coronary surgery; however, insertion may be harmful or contraindicated in severe and diffuse atherosclerosis of the descending aorta and peripheral arteries. We report our experience with 10 consecutive patients with severe peripheral atherosclerosis or distal abdominal aortic aneurysms, in whom a 7.5F intraaortic balloon catheter was inserted through the brachial artery. Intraaortic balloon pumping was maintained until hemodynamic stability was established; no complications or ischemia of the hand related to the intraaortic balloon pump occurred. Transbrachial intraaortic balloon pumping with a 7.5F catheter is as safe and effective as the transfemoral method in patients with unavailable femoral arteries.

Cardiology, Lower Bucks Hospital, Bristol, USA.
This case report presents a 37-year-old male with a complex medical history, including HIV, chronic methamphetamine and cocaine use, and an atrial septal defect, who developed severe pulmonary arterial hypertension (PAH), biventricular failure, and recurrent stroke. The patient was admitted with acute neurological deficits and respiratory failure, which rapidly progressed despite intensive management. Laboratory and imaging studies revealed severe cardiac dysfunction and elevated pulmonary vascular resistance.

Background: Transcatheter edge-to-edge mitral valve repair (M-TEER) using the MitraClip system is primarily performed using the transfemoral approach. However, when this approach is not feasible, the transjugular approach can be used as an alternative.
Case Summary: A 57-year-old man presented with heart failure and persistent New York Heart Association class IV symptoms, refractory to guideline-directed medical therapy, intravenous therapy, and intra-aortic balloon pumping.
Mechanical Circulatory Support for Acute Myocardial Infarction Cardiogenic Shock: Review and Recent Updates.
J Cardiothorac Vasc Anesth

Department of Anesthesiology, Perioperative and Pain Medicine, Brigham and Women's Hospital, Boston, MA.
Cardiogenic shock (CS) in acute myocardial infarction (AMI) is a life-threatening syndrome characterized by systemic hypoperfusion that can quickly progress to multiorgan failure and death. Various devices and configurations of mechanical circulatory support (MCS) exist to support patients, each with unique pathophysiological characteristics. The Intra-aortic balloon pump can improve coronary perfusion, decrease afterload, and indirectly augment cardiac output.

- Patients awaiting heart transplants often require colonoscopies due to bleeding or screening needs, but there's limited research on the safety of these procedures for individuals on inotropic medications or mechanical circulatory support.
- A study was conducted from 2015 to 2021 with 92 heart failure patients undergoing colonoscopy while on advanced heart failure therapies, such as inotropes or mechanical devices.
- Results indicated that the most common reason for colonoscopy was cancer screening, with significant findings including 8% of screening procedures revealing advanced adenomas and 17% of bleeding-related colonoscopies identifying sources needing intervention, but no major complications related to anesthesia were reported.
Surgical treatment experience of seven cases of Berry syndrome.
J Cardiothorac Surg
December 2024
Beijing Children's Hospital Capital Medical University Beijing, Beijing, China.
Objective: Berry syndrome is a group of rare congenital cardiac malformations including aortopulmonary window (APW), aortic origin of the right pulmonary artery (AORPA), interruption of the aortic arch (IAA), patent ductus arteriosus (PDA) (supplying the descending aorta) and intact ventricular septum. This paper will analyze the clinical data of 7 patients with Berry syndrome who underwent surgical treatment in our institution and discuss the one-stage surgical correction of Berry syndrome in combination with the literature.
Methods: From January 2013 to July 2024, a total of 7 children with Berry syndrome were admitted to the Cardiac Surgery Department of Beijing Children's Hospital.
