BACKGROUND: Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) may be less effective in small surgical valves because of patient/prosthesis mismatch. Bioprosthetic valve fracture (BVF) using a high-pressure balloon can be performed to facilitate VIV TAVR. METHODS AND RESULTS: We report data from 20 consecutive clinical cases in which BVF was successfully performed before or after VIV TAVR by inflation of a high-pressure balloon positioned across the valve ring during rapid ventricular pacing...

BACKGROUND: Valve-in-valve transcatheter aortic valve replacement is less effective in small surgical bioprostheses. We evaluated the feasibility of bioprosthetic valve fracture with a high-pressure balloon to facilitate valve-in-valve transcatheter aortic valve replacement. METHODS: In vitro bench testing on aortic tissue valves was performed on 19-mm and 21-mm Mitroflow (Sorin, Milan, Italy), Magna and Magna Ease (Edwards Lifesciences, Irvine, CA), Trifecta and Biocor Epic (St...

BACKGROUND: Outcomes after surgical pulmonary valve replacement (PVR) in patients with congenital cardiac disease are limited by long-term valve deterioration, which may be hastened by turbulent flow. The use of the Trifecta valve (St. Jude Medical, Little Canada, MN) at our institution (Duke University Medical Center, Durham, NC) appears to result in low postimplantation transvalvular gradients. This study was performed to compare the early transvalvular gradient associated with the Trifecta valve with that associated with two other valves commonly used for PVR...

In the last years, a general shift toward the use of surgical bioprosthetic aortic valves rather than mechanical valves with subsequent less use of anticoagulant therapy has been observed. However, bioprosthetic valves have limited durability. Reoperation, the current standard of care for these patients, carries a high surgical risk, especially because patients are elderly and with numerous comorbidities. Recently, transcatheter aortic valve replacement within a failed bioprosthetic valve (valve-in-valve procedure) has proven feasible...

BACKGROUND: The aim was to assess the incidence of prosthesis-patient mismatch (PPM) after mitral valve replacement (MVR) in patients receiving Biocor® porcine or mechanical valves, and to evaluate the effect of PPM on long-term survival. METHODS: All patients undergoing MVR between 2009 and 2013 received either mechanical or bioprosthetic valves (Biocor® porcine). PPM was defined as severe when the indexed effective ori-fice area was < 0.9 cm2/m2, moderate between 0...

Transcatheter "Valve-in-Valve" implantation (ViV) has shown promising results in high-risk patients suffering from structural valve deterioration (SVD) of a previously implanted heart valve bioprosthesis. We present a case of a 68-year-old woman with a history of three previous cardiac operations on the aortic and mitral valve. At the time of admission she was severely symptomatic due to a simultaneous SVD of a 23 mm aortic and of a 29 mm mitral St. Jude Biocor bioprosthesis. Because of the history of several cardiac operations and to her comorbidities, the patient was considered with an extremely high surgical risk profile and was therefore scheduled for double concomitant mitral and aortic ViV...

BACKGROUND AND AIM OF THE STUDY: Currently, there is no universal standard for sizing bioprosthetic aortic valves. Hence, a standardized comparison was performed to clarify this issue. METHODS: Every size of four commercially available bioprosthetic aortic valves marketed in the United States (Biocor Supra; Mosaic Ultra; Magna Ease; Mitroflow) was obtained. Subsequently, custom sizers were created that were accurate to 0.0025 mm to represent aortic roots 18 mm through 32 mm, and these were used to measure the external diameter of each valve...

OBJECTIVES: Pulmonary valve replacement (PVR) is performed to reduce right ventricular (RV) volume overload, resulting in improved ventricular function and clinical status. Significant pulmonary regurgitation (PR) after tetralogy of Fallot (TOF) repair could result in RV dysfunction, exercise intolerance, arrhythmia and sudden death. The present study was conducted to investigate the mid-term clinical outcomes of PVR after TOF repair. METHODS: Between 2001 and 2010, we retrospectively reviewed the outcomes of 131 (89 males and 42 females) PVRs with PR or pulmonary steno-insufficiency after TOF repair...

BACKGROUND AND AIM OF THE STUDY: The American College of Cardiology/American Heart Association (ACC/AHA) guidelines recommend a three-month administration of warfarin following bioprosthetic valve replacement (BVR). However, strong evidence supporting this recommendation is lacking, making process variation likely. METHODS: In the ANSWER Registry, a total of 386 patients who had received either Epic or Biocor BVRs between May 2007 and August 2008 at 40 centers was enrolled...

BACKGROUND: Pericardial bioprostheses have favorable echocardiographic hemodynamics in the aortic position compared with porcine valves; however, there are few data comparing clinical outcomes. Our objective was to assess the late results of the two valve types. METHODS: We reviewed 2,979 patients aged 65 years or older undergoing aortic valve replacement with pericardial (n=1,976) or porcine (n=1,003) prostheses between January 1993 and December 2007. The most common pericardial prostheses were Carpentier-Edwards Perimount and Mitroflow, and the most common porcine valves were Medtronic Mosaic, Carpentier-Edwards, Hancock modified orifice, and St...

OBJECTIVE: Patients who require aortic valve replacement are increasingly receiving biologic valves to avoid long-term anticoagulation. The thromboembolic risk of bioprosthetic valves is reportedly low. The study objective was to review the incidence of early valve thrombosis requiring reoperation in patients who received a bioprosthetic valve in the aortic position. METHODS: We reviewed all adult patients who had a biologic valve implanted in the aortic position at Mayo Clinic between January 1993 and July 2009...

BACKGROUND: The St Jude Medical Epic heart valve (St Jude Medical, Inc, St Paul, Minn) is a tricomposite glutaraldehyde-preserved porcine bioprosthesis. The St Jude Medical Biocor porcine bioprosthesis is the precursor valve to the St Jude Medical Epic valve. The Epic valve is identical to the Biocor valve except that it is treated with Linx AC ethanol-based calcium mitigation therapy. METHODS: The St Jude Medical Epic valve was implanted in 761 patients (mean age 73...

OBJECTIVE: The 20-year data from the ongoing long-term study of the St Jude Medical Biocor (St Jude Medical, St Paul, Minn) porcine bioprosthesis are reported. Earlier follow-ups have shown that the valve has excellent durability. After 20 years, will this continue to be true? METHODS: Data were obtained for 1712 patients who underwent valve replacement (1518 aortic valve replacements; 194 mitral valve replacements) with glutaraldehyde-preserved Biocor bioprostheses at Sahlgrenska University Hospital (Sweden) between 1983 and 2003...

The aims of the present study were to investigate in vivo Doppler-catheter discrepancies in aortic bileaflet mechanical and stented biologic valves and evaluate whether these can be predicted using Doppler echocardiography. Results of in vitro studies of bileaflet mechanical valves suggested overestimation using Doppler gradients. Findings in stented biologic valves were conflicting. Patients who underwent valve replacement with a St. Jude Medical mechanical (n = 14, size 19 to 29) or a St. Jude Medical Biocor (Biocor, n = 13, size 21 to 25) valve were included...
