BACKGROUND: Balloon pre-dilatation before transcatheter aortic valve replacement (TAVR) is performed at the discretion of the treating physician. Clinical data assessing the implications of this step on procedural outcomes are limited. METHODS: We conducted a retrospective analysis of 1164 consecutive TAVR patients in the Israeli multicenter TAVR registry (Sheba, Rabin, and Tel Aviv Medical Centers) between the years 2008 and 2014. Patients were divided to those who underwent balloon pre-dilation (n=1026) versus those who did not (n=138)...

A 70-year-old woman with a history of aortic valve replacement and coronary artery bypass grafting (CABG) was transferred to the authors' hospital for further management of a three-month fever of unknown origin. Computed tomography showed a huge mass in the ascending aorta with pseudoaneurysm. Blood β-D-glucan levels were significantly high, and blood culture showed the growth of Candida albicans. The fungus ball was excised surgically, together with aortic root replacement and CABG, followed by six-month postoperative anti-fungal therapy...

We report a rare case of prosthetic valve fungal endocarditis caused by Lichtheimia, a subspecies of the order Mucorales. The patient experienced complicated prosthetic valve endocarditis less than 2 months after uneventful coronary artery bypass grafting (CABG) and 2 aortic valve replacements. Ultimately surgical management required aortic root replacement and lifelong antimicrobial agents. We believe this is the first case of fungal endocarditis caused by Lichtheimia.

BACKGROUND: The risk of permanent pacemaker implantation (PPI) after cardiac valve replacement surgery is thought to be highest in the postoperative period. Long-term risks are uncertain. OBJECTIVE: The purpose of this study was to determine rates and timing of PPI after cardiac valve replacement surgery. METHODS: We compared PPI rates of patients undergoing aortic valve replacement (AVR; n = 111,674), mitral valve replacement (MVR; n = 18,402), AVR + MVR (n = 5166), AVR + MVR + tricuspid valve replacement (TVR; n = 114), or coronary artery bypass surgery (CABG) without valve replacement (n = 249,742)...

BACKGROUND: Transapical approach (TA) is an established access alternative to the transfemoral technique in patients undergoing transcatheter aortic valve replacement (TAVR) for treatment of symptomatic aortic valve stenosis. The impact of prior coronary artery bypass grafting (CABG) on clinical outcomes in patients undergoing TA-TAVR is not well defined. METHODS: A single center retrospective cohort analysis of 126 patients (male 41%, mean age 85.8 ± 6.1 years) who underwent TA balloon expandable TAVR (Edwards SAPIEN, SAPIEN XT or SAPIEN 3) was performed...

BACKGROUND: The best management strategy for patients with coronary disease and mild to moderate AS requires the clinician to consider the operative risks of isolated coronary artery bypass grafting (CABG) against the risks of untreated aortic stenosis (AS). METHODS: Between 2000 and 2014, isolated off-pump CABG (OPCAB) was performed in 2023 patients. Of these patients, 103 presented with mild or moderate AS (mean age 72.7±6.3 years; 23 females), 96 (93.2%) presented with mild AS and seven (6...

OBJECTIVES: The aim of this study was to assess how the introduction of transcatheter aortic valve replacement (TAVR) has changed clinical practice and outcome in patients who have previously undergone coronary artery bypass grafting (CABG). BACKGROUND: A significant proportion of patients admitted for aortic valve replacement have previously undergone CABG and are therefore at increased operative risk in case of redo surgery. METHODS: In-hospital outcome data were analyzed from patients with or without previous CABG undergoing isolated surgical aortic valve replacement or TAVR in Germany from 2007 to 2013...

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) is generally more expensive than surgical aortic valve replacement (SAVR) due to the high cost of the device. Our objective was to understand the patient and procedural drivers of cumulative healthcare costs during the index hospitalisation for these procedures. DESIGN: All patients undergoing TAVI, isolated SAVR or combined SAVR+coronary artery bypass grafting (CABG) at 7 hospitals in Ontario, Canada were identified during the fiscal year 2012-2013...

BACKGROUND: The use of rapid-deployment aortic valve replacement (RD-AVR) has burgeoned in recent years. There are few studies comparing RD-AVR to conventional aortic valve replacement (cAVR) and no studies where both were inserted via full sternotomy. As such, we reviewed our experience and compared the two approaches. METHODS: From 2008 to 2015, 597 patients underwent isolated aortic valve replacement ± coronary artery bypass grafting (CABG) at a single centre...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become an alternative procedure for treating aortic stenosis (AS) in patients with advanced age and severe comorbidities. Ischemic heart disease (IHD) is present with AS in 40-50% of patients with typical angina. Considering the high operative mortality and morbidity rates in these patients, hybrid TAVI and off-pump CABG (OPCAB) have become realistic treatment options. METHODS AND RESULTS: Between August 2014 and November 2015, 12 patients were evaluated for simultaneous TAVI and OPCAB...

History of prior coronary artery bypass surgery (CABG) is a frequent scenario encountered in patients with severe symptomatic aortic stenosis deemed inoperable and referred for transcatheter aortic valve replacement (TAVR). Aside from indices of frailty and other comorbidities, these patients remain at higher risk for peri-operative mortality and morbidity compared to their counterparts without prior CABG. Presence of concomitant peripheral arterial disease and patent left internal mammary artery (LIMA) graft pose further access related challenges...

INTRODUCTION: The need for permanent pacemaker implantation (PCM) following surgical aortic valve replacement (SAVR) is uncommon but can lead to increased hospital resource utilization. Using nationwide data, we sought to (1) identify hospital, patient, and procedure-level risk factors for PCM after SAVR and (2) determine incremental resource utilization. METHODS: We identified 659,692 patients from the Nationwide Inpatient Sample database who underwent SAVR with or without coronary artery bypass grafting (CABG), mitral valvuloplasty (MVr), or mitral valve replacement (MVR) between 1998 and 2009...

BACKGROUND: Aortic valve replacement (AVR) and/or coronary artery bypass grafting (CABG) make up the majority of cardiac surgery with increasing demand as the population ages. Accuracy of risk stratification is important, in predicting adverse outcomes and selecting modality of intervention, but has been rarely studied for the combined AVR+CABG operation. We compared the prognostic utility of EuroSCORE, EuroSCORE II and Society of Thoracic Surgeons' (STS) Score for AVR+CABG. METHODS: All patients (n=450) undergoing AVR+CABG at Auckland City Hospital during 2005-2012 with mean follow-up of 4...
