Comparison of the short-term outcomes between Y-incision aortic annular enlargement and traditional aortic annular enlargement techniques.

Background: The short-term efficacy and safety of the Y-incision technique of aortic annular enlargement (AAE) has been established. We aimed to determine how the short-term outcomes of the Y-incision technique compared to traditional AAE techniques.

Methods: From February 2011 to June 2022, 380 patients at the University of Michigan Hospital underwent aortic valve replacement (AVR) with AAE using either traditional annular enlargement techniques (Traditional group, n=270), including Nicks [63% (171/270)], Manouguian [34% (91/270)], and others [3% (8/270)], or the Y-incision technique (Y-incision group, n=110).

How-I-Do-It: Aortic Annular Enlargement - Are the Nicks and Manouguian Obsolete?

The Y-incision aortic annular enlargement (AAE), first performed in August 2020, offers a safe and more effective alternative for management of a small aortic annulus/root without need for violation of the left ventricular outflow tract, mitral valve geometry, or left/right atria in both first-time aortic valve replacement (AVR) and reoperative AVR. In the first consecutive 119 patients with Y-incision AAE, the median age was 65 (59, 71), 67% female, 28% had previous cardiac surgery, and 2 cases had endocarditis. The preoperative mean gradient was 36 (30, 47), and the native aortic valve area was 0.

Late Outcomes of Konno-Rastan and Modified Konno for Left Ventricular Outflow Tract Obstruction.

Background: While early outcomes of the Konno-Rastan and modified Konno procedures are known, long-term outcomes remain undetermined. Our objective was to examine long-term clinical and echocardiographic outcomes.

Methods: Retrospective review was performed of patients undergoing Konno-Rastan and modified Konno for complex left ventricular outflow tract (LVOT) obstruction from January 1980 to January 2021.

Pulmonary Artery Sarcoma Complete Resection Facilitated by 3-Dimensional Printed Model.

Primary pulmonary artery sarcomas are rare tumors and are commonly misdiagnosed as pulmonary embolism. Primary pulmonary sarcomas demonstrate intraluminal growth into the vessel, rather than through the wall; require complete resection to enhance survival; and require complex surgical planning. The purpose of this case report is to describe an optimal team approach with multidisciplinary planning facilitated by a customized 3-dimensional model to guide intervention and enhance communication.

Intra-atrial Pulmonary Venous Conduit Leak in Criss-Cross Heart: Role of Three-Dimensional Modeling.

Three-dimensional (3D) modeling has become an invaluable tool for operative planning in the continually evolving complex field of adult congenital heart surgery. We present a case of an intra-atrial conduit leak after multiple repairs of common atrium and criss-cross morphology. 3D modeling was critical in preoperative evaluation and operative planning for complicated intracardiac anatomy after an uncommon initial approach to preserve a biventricular circulation.

Atlanto-Occipital Transarticular Screw Fixation for the Treatment of Traumatic Occipitocervical Instability in the Pediatric Population.

Background: Atlanto-occipital transarticular screw fixation (AOTSF) has rarely been reported for fixation of the craniovertebral junction (CVJ).

Methods: A retrospective chart review of all pediatric patients (less than 18 years of age) with an attempt of AOTSF for fixation of traumatic CVJ instability was conducted.

Results: A total of 4 patients (2 boys and 2 girls; ages 2, 3, 5, and 8 years) who suffered from acute traumatic CVJ instability managed during 2007-2018 underwent an attempted AOTSF.

Review of Operative Treatment of Delayed Presentation of Acute Cholecystitis.

Treatment of patients with delayed acute cholecystitis (AC) includes antibiotics and interval cholecystectomy based on proposed change at 72 hours from symptom onset to a chronic fibrotic phase with concern for increased complication rates. The purpose of our study was to compare the outcomes of patients undergoing laparoscopic cholecystectomy (LC) for AC before and after this golden 72-hour window. After institutional review board approval, a retrospective study was performed of patients presenting over two years with AC, who underwent LC during the index admission.

Endovascular retrieval of foreign body in persistent left-sided superior vena cava.

Endovascular retrieval of a foreign body is becoming an increasingly common procedure in the management of complications resulting from more frequent endovascular procedures. Many procedures are performed on a regular basis in assessment of vascular anatomy, endovascular-guided therapy, and catheter placement. This case report depicts a complication of a chemoport placement resulting in a foreign body.
