Significance of Interstitial Lung Disease on Outcomes Following Cardiac Surgery.

Interstitial lung disease (ILD) is a known risk factor for noncardiac surgery due to acute pulmonary exacerbations but its impact after cardiac surgery is not known. We examined perioperative outcomes and risk factors for long-term survival in ILD patients who underwent cardiac surgery. From January 2002 to June 2017, 294 cardiac surgery patients with a previous ILD diagnosis, including 75 patients with idiopathic pulmonary fibrosis (IPF), were identified.

Impact of Prosthesis Size and Prosthesis-Patient Mismatch on Outcomes in Younger Female Patients Undergoing Aortic Valve Replacement.

The effects of patient-prosthesis mismatch (PPM) after surgical aortic valve replacement (SAVR) suggest worse outcomes with smaller valves. We assessed clinical outcomes of younger females undergoing SAVR, using small and large prostheses, and the incremental risk of PPM. Between January 2002 and June 2015, 451 younger (age ≤65 years) female patients underwent SAVR.

Decreased preoperative functional status is associated with increased mortality following coronary artery bypass graft surgery.

Objectives: Functional status prior to coronary artery bypass graft surgery may be a risk factor for post-operative adverse events. We sought to examine the association between functional status in the 3 months prior to coronary artery bypass graft surgery and subsequent 180 day mortality.

Design, Setting, And Participants: We performed a single center retrospective cohort study in 718 adults who received coronary artery bypass graft surgery from 2002 to 2014.

Current Readings: Single vs Bilateral Internal Mammary Artery in Coronary Artery Bypass Grafting.

There is strong retrospective data demonstrating that bilateral internal mammary artery (BIMA) grafting leads to better long-term survival as compared to left internal mammary artery grafting. However, this survival advantage was not corroborated by the interim results of the Arterial Revascularization Trial. Today, there are barriers to widespread adoption of BIMA grafting.

Outcomes of repeat mitral valve replacement in patients with prior mitral surgery: A benchmark for transcatheter approaches.

Objectives: With the emergence of transcatheter mitral valve-in-valve/ring replacement for deteriorated bioprostheses or failed repair, comparative clinical benchmarks for surgical repeat mitral valve replacement (re-MVR) are needed. We present in-hospital and survival outcomes of a 24-year experience with re-MVR.

Methods: From January 1992 to June 2015, 520 adult patients underwent re-MVR; 273 had undergone prior mitral valve repair (pMVP) and 247 had undergone prior MVR (pMVR).

Surgical pulmonary embolectomy and catheter-directed thrombolysis for treatment of submassive pulmonary embolism.

Background: Acute pulmonary embolism (PE) with preserved hemodynamics but right ventricular dysfunction, classified as submassive PE, carries a high risk of mortality. We report the results for patients who did not qualify for medical therapy and required treatment of submassive PE with surgical pulmonary embolectomy and catheter-directed thrombolysis (CDT).

Methods: Between October 1999 and May 2015, 133 submassive PE patients underwent treatment with pulmonary embolectomy (71) and CDT (62).

Novel fast-track recovery protocol for alternative access transcatheter aortic valve replacement: application to non-femoral approaches.

Objectives: Although the transfemoral approach for transcatheter aortic valve replacement is the preferred choice, alternative access remains indicated for inadequate iliofemoral vessels. We report the successful implementation of a novel fast-track (FT) protocol for patients undergoing alternative access transcatheter aortic valve replacement compared with conventional controls.

Methods: Between September 2014 and January 2017, 31 and 23 patients underwent alternative access transcatheter aortic valve replacement under FT and pre-fast-track (p-FT) protocols, respectively.

Severity of tricuspid regurgitation is associated with long-term mortality.

Objectives: To determine the association between intraoperative/presurgical grade of tricuspid regurgitation (TR) and mortality, and to determine whether surgical correction of TR correlated with an increased chance of survival compared with patients with uncorrected TR.

Methods: The grade of TR assessed by intraoperative transesophageal echocardiography (TEE) before surgical intervention was reviewed for 23,685 cardiac surgery patients between 1990 and 2014. Cox proportional hazard regression models were used to determine association between grade of TR and the primary endpoint of all-cause mortality.

Management of Reducible Ventral Hernias: Clinical Outcomes and Cost-effectiveness of Repair at Diagnosis Versus Watchful Waiting.

Objective: To compare long-term clinical and economic outcomes associated with 3 management strategies for reducible ventral hernia: repair at diagnosis (open or laparoscopic) and watchful waiting.

Background: There is variability in ventral hernia management. Recent data suggest watchful waiting is safe; however, long-term clinical and economic outcomes for different management strategies remain unknown.

Effectiveness and Safety of Transcatheter Aortic Valve Implantation for Aortic Stenosis in Patients With "Porcelain" Aorta.

Surgical aortic valve replacement (SAVR) in patients with porcelain aorta is considered a high-risk procedure. Hence, transcatheter aortic valve implantation (TAVI) is emerging as the intervention of choice. However, there is a paucity of data directly comparing TAVI with SAVR in patients with porcelain aorta.

Should the dilated ascending aorta be repaired at the time of bicuspid aortic valve replacement?

Objectives: Bicuspid aortic valve (BAV) is the most common congenital valvular abnormality and frequently presents with accelerated calcific aortic valve disease, requiring aortic valve replacement (AVR) and thoracic aortic aneurysm and dissection. Supporting evidence for Association Guidelines of aortic dimensions for aortic resection is sparse. We sought to determine whether concurrent repair of dilated or aneurysmal aortic disease during AVR in patients with BAV substantially improves morbidity and mortality outcomes.

Parsimonious assessment for reoperative aortic valve replacement; the deterrent effect of low left ventricular ejection fraction and renal impairment.

Background: Patient comorbidities play a pivotal role in the surgical outcomes of reoperative aortic valve replacement (re-AVR). Low left ventricular ejection fraction (LVEF) and renal insufficiency (Cr >2 mg/dL) are known independent surgical risk factors. Improved preoperative risk assessment can help determine the best therapeutic approach.

Outcomes of surgical and transcatheter aortic valve replacement in the octogenarians-surgery still the gold standard?

Background: Contemporary options for aortic valve replacement (AVR) include transcatheter and surgical approaches (TAVR and SAVR). As evidence accrues for TAVR in high and intermediate risk patients, some clinicians advocate that all patients aged over 80 years should only receive TAVR. Our aim was to investigate the utility of SAVR and minimally invasive AVR (mAVR) among octogenarians in the current era of TAVR.

The risk of reoperative cardiac surgery in radiation-induced valvular disease.

Objective: Mediastinal radiation therapy (MRT) increases the risk for adverse outcomes after cardiac surgery and is not incorporated in the Society of Thoracic Surgeons (STS) risk algorithm. We aimed to quantify the surgical risk conferred by MRT in patients undergoing primary and reoperative valvular operations.

Methods: A retrospective analysis of 261 consecutive patients with prior MRT who underwent valvular operations between January 2002 and May 2015.

Surgical outcomes of isolated tricuspid valve procedures: repair versus replacement.

Background: Isolated tricuspid valve (ITV) operations are infrequent and the decision to operate is controversial. We report a series of ITV operations to outline the current disease status requiring this uncommon procedure with an emphasis on the results of tricuspid valve repair (TVr) versus replacement (TVR).

Methods: Using our prospective cardiac surgery database, 57 patients who underwent ITV operations between 01/02-03/14 were identified.

Aortic Atheroma Increases the Risk of Long-Term Mortality in 20,000 Patients.

Background: The association between long-term survival and aortic atheroma in cardiac surgical patients has not been comprehensively investigated. In this study we determine the relation between grade of atheroma and the risk of long-term mortality in a retrospective cohort of more than 20,000 patients undergoing cardiac operation during a 20-year period.

Methods: We included 22,304 consecutive intraoperative transesophageal and epiaortic ultrasound examinations performed at Brigham and Women's Hospital between 1995 and 2014, with long-term follow-up.

Vancomycin Paste Does Not Reduce the Incidence of Deep Sternal Wound Infection After Cardiac Operations.

Background: Deep sternal wound infection (DSWI) is a devastating complication that increases morbidity and death in cardiac surgical patients. Vancomycin is often administered intravenously for antibiotic prophylaxis in cardiac operations. Many cardiac surgeons also apply vancomycin paste topically to the sternal edges.

Reoperative Surgical Aortic Valve Replacement Versus Transcatheter Valve-in-Valve Replacement for Degenerated Bioprosthetic Aortic Valves.

Background: Bioprosthetic aortic valve use has increased steadily according to The Society of Thoracic Surgeons (STS) database analyses. One of the momentums toward this trend is the future utilization of transcatheter valve-in-valve (TViV) techniques when bioprosthetic valves fail. We compared the results of reoperative TViV to surgical aortic valve replacement (SAVR) for degenerated bioprosthetic valves.

Should Moderate-to-Severe Tricuspid Regurgitation be Repaired During Reoperative Left-Sided Valve Procedures?

The risks vs benefits of tricuspid valve (TV) surgery in reoperative patients requiring left-sided valve surgery and moderate-to-severe tricuspid regurgitation is unclear. We compared patients with and without concomitant TV surgery. A total of 200 patients with moderate-to-severe TV regurgitation had reoperative left-sided valve procedures from January 2002 to April 2014; 75 with TV intervention (TVI) and 125 with no tricuspid intervention (TVN).

Surgical outcomes of infective endocarditis among intravenous drug users.

Background: With increasing prevalence of injected drug use in the United States, a growing number of intravenous drug users (IVDUs) are at risk for infective endocarditis (IE) that may require surgical intervention; however, few data exist about clinical outcomes of these individuals.

Methods: We evaluated consecutive adult patients undergoing surgery for active IE between 2002 and 2014 pooled from 2 prospective institutional databases. Death and valve-related events, including reinfection or heart valve reoperation, thromboembolism, and anticoagulation-related hemorrhage were evaluated.

Aortic Regurgitation With Markedly Reduced Left Ventricular Function Is Not a Contraindication for Aortic Valve Replacement.

Background: The current study assesses outcomes and risk factors for aortic valve replacement (AVR) for aortic regurgitation (AR) in the setting of markedly reduced left ventricular (LV) function compared with moderately reduced LV function and preserved LV function.

Methods: Between January 2002 and June 2013, 485 consecutive patients underwent AVR for severe AR. Overall, 37 of 485 patients (8%) had an LV ejection fraction (EF) less than or equal to 35% (low EF) with median of 30%; 141 of 485 patients (27%) had an LVEF of 36% to 50% (moderate) with median of 45%, and 307 of 485 patients (65%) had an LVEF greater than 50% (preserved) with median of 60%.

Are homografts superior to conventional prosthetic valves in the setting of infective endocarditis involving the aortic valve?

Background: Surgical dogma suggests that homografts should be used preferentially, compared with conventional xenograft or mechanical prostheses, in the setting of infective endocarditis (IE), because they have greater resistance to infection. However, comparative data that support this notion are limited.

Methods: From the prospective databases of 2 tertiary academic centers, we identified 304 consecutive adult patients (age ≥17 years) who underwent surgery for active IE involving the aortic valve (AV), in the period 2002 to 2014.
