Neonatal Gerbode Defect Resulting in Cardiogenic Shock.
Ann Thorac Surg Short Rep
September 2023
Department of Surgery, Duke University Medical Center, Durham, North Carolina.
Congenital Gerbode defects, consisting of a deficiency in the membranous septum causing left ventricle-to-right atrium shunting, are rarely hemodynamically significant. Here, we present the case of a neonate with a large unrestrictive Gerbode defect, patent foramen ovale, patent ductus arteriosus, and pulmonary valve insufficiency resulting in a circular intracardiac shunt and cardiogenic shock. The patient was managed with venoarterial extracorporeal membrane oxygenation followed by neonatal Gerbode defect repair.

Department of Cardiovascular Surgery, Rinku General Medical Center, Osaka, Japan.
The mortality rate of postcardiotomy cardiogenic shock after cardiovascular surgery is quite high, and the only way to avoid this serious complication is to initiate a preemptive strategy during surgery. The Impella 5.5 device with the SmartAssist system (Abiomed) is mainly used to prevent or to treat cardiogenic shock in cardiac surgery, but it is not often used in aortic surgery.

Ann Thorac Surg Short Rep
December 2024
Duke University Medical Center, Durham, North Carolina.
Background: Direct mechanical ventricular actuation (DMVA) with the Anstadt cup is effective for non-blood-contacting biventricular support. Pneumatic regulation of a silicone device augments ventricular pump function. Vacuum attachment facilitates diastolic augmentation critical for biventricular support.

Ann Thorac Surg Short Rep
March 2024
Department of Cardiovascular Surgery, Shonan Kamakura General Hospital, Kamakura-shi, Kanagawa, Japan.
A 72-year-old man was diagnosed with posterior ventricular septal rupture after acute myocardial infarction with dissection in the posterior wall of the ventricular septum. On admission, cardiogenic shock was identified, and an Impella CP was inserted to improve his hemodynamics. Extended sandwich patch repair through the right ventricle with a Dacron patch was successfully performed, achieving an excellent postoperative course with stable hemodynamics.

Cardiovasc Diagn Ther
December 2024
Department of Cardiovascular Medicine, National Cerebral & Cardiovascular Center, Suita, Japan.
Background: The Society of Cardiovascular Angiography and Intervention (SCAI) has defined 5 stages of cardiogenic shock (CS). In patients with acute myocardial infarction (AMI) who initially present in stable hemodynamic condition (SCAI CS stage: A or B), CS stages could deteriorate despite therapeutic management. However, deterioration of SCAI CS stages after AMI remains to be fully characterized.
