Enterococcus faecalis endocarditis resulting in annular rupture: a case report.

Enterococcus faecalis is the third most common organism to cause infective endocarditis and is associated with high rates of morbidity and mortality. E. faecalis infective endocarditis often presents with a subacute course and with nonspecific constitutional symptoms. Complications related to E. faecalis infective endocarditis are common and include embolic events, abscess formation and pseudoaneurysm formation. Contained annular rupture is a complication of E. faecalis infective endocarditis that, to the authors knowledge, has not been previously described in the literature. Herein, we present an unusual case of a 62-year-old male presenting with classical symptoms of E. faecalis infective endocarditis which resulted in an unusual complication of this condition, a contained annular rupture and the surgical management undertaken to correct this condition.

Enterococcus faecalis is the third most common organism to cause infection of the heart and heart valves and is associated with high rates of complications and death. Complications related to E. faecalis heart infections are common and include dislodging of infected material, abscess formation and injury to blood vessel walls. Contained rupture of the aortic valve annulus is a complication of E. faecalis infections that, to the authors knowledge, has not been previously described in the literature. Herein, we present an unusual case of a 62-year-old male presenting with classical symptoms of E. faecalis infection of the heart which resulted in an unusual complication of this condition, a contained annular rupture and the surgical management undertaken to correct this condition.

Mini-sternotomy versus full sternotomy for isolated aortic valve replacement: A single-center experience.

BACKGROUND: Minimally invasive approaches to isolated aortic valve replacement (AVR) are well-described and widely utilized. While there are numerous proposed benefits, there is limited literature describing significant morbidity or mortality benefits for minimally invasive isolated AVR resulting in hesitancy in its universal adoption. In this retrospective study, we compare the 5-year outcomes of patients undergoing isolated AVR via full sternotomy (FS) or mini-sternotomy (MS). METHODS: 756 patients underwent isolated AVR between 2014 and 2019. Propensity matching resulted in 142 matched pairs that received either FS or MS. The primary outcome was mortality during the follow-up period. Secondary outcomes included intraoperative variables and postoperative morbidity. RESULTS: Intraoperative variables including total operative, cardiopulmonary bypass, and aortic cross-clamp times did not differ significantly between groups. Postoperative mortality was similar between the matched groups with nonsignificant differences at 30 days (2.12% vs. 1.4%, p = .657), 1 year (4.9% vs. 2.1%, p = .0.223), and 5 years (7.5% vs. 3.5%, p = .174). Rates of postoperative morbidity were comparable between groups with no significant differences. CONCLUSION: This study examined the long-term outcomes of propensity-matched patients undergoing isolated AVR via FS or MS and identified no significant differences in outcomes over a 5-year follow-up period. The decision for surgical approach is multifactorial and should be decided on a case-by-case basis taking into consideration patient anatomy, surgeon experience, and comfort, as well as patient preference.

Aortic Valve Replacement: Is Minimally Invasive Really Better? A Contemporary Systematic Review and Meta-Analysis.

In recent years, minimally invasive cardiac surgery has increased in prevalence. There has been significant debate regarding the optimal approach to isolated aortic valve replacement between conventional midline sternotomy and minimally invasive approaches. We performed a systematic review of the contemporary literature comparing minimally invasive to full sternotomy aortic valve replacement. PubMed and Embase were systematically searched for articles published from 2010-2021. A total of 1215 studies were screened and 45 studies (148,606 patients total) met the inclusion criteria. This study found rates of in-hospital mortality were higher with full sternotomy than ministernotomy (P = 0.02). 30-day mortality was higher with full sternotomy compared to right anterior thoracotomy (P = 0.006). Renal complications were more common with full sternotomy versus ministernotomy (P < 0.00001) and right anterior thoracotomy (P < 0.0001). Rates of wound infections were greater with full sternotomy than ministernotomy (P = 0.02) and right anterior thoracotomy (P < 0.00001). Intensive care unit length of stay (P = 0.0001) and hospital length of stay (P < 0.0001) were shorter with ministernotomy compared to full sternotomy. This review found that minimally invasive approaches to isolated aortic valve replacement result in reduced early mortality and select measures of postoperative morbidity; however, long-term mortality is not significantly different based on surgical approach. An analysis of mortality alone is not sufficient for the selection of the optimal approach to isolated aortic valve replacement. Surgeon experience, individual patient characteristics, and preference require thorough consideration, and additional studies investigating quality of life measures will be imperative in identifying the optimal approach to isolated aortic valve replacement.

Surgical Repair of a Transannular Rupture During Transfemoral Transcatheter Aortic Valve Replacement.

Annular rupture is a rare but life-threatening complication of transcatheter aortic valve replacement (TAVR). Mortality rates are high if immediate intervention, most often necessitating surgical repair, is not performed. Herein, we describe an 87-year-old man who, after deployment of TAVR, experienced acute decompensation and required urgent conversion to a midline sternotomy to repair an aortic annular rupture. This case demonstrates an example of a rare but severe complication of TAVR. This report provides an in-depth description of the surgical approach to repair an aortic annular rupture and demonstrates the utility of performing minimally invasive procedures inside a hybrid operating room.
