BACKGROUND: Transcatheter aortic valve replacement (TAVR) is often associated with intraventricular conduction disturbances. We aimed to determine the association between implantation depth assessed by multidetector computed tomography (MDCT) and new-onset conduction abnormalities after TAVR. METHODS: Retrospective single-center study including patients consecutively submitted to TAVR, between August/2007 and October/2016, who underwent routine MDCT 3 months after the procedure...

BACKGROUND: The inflammatory process in aortic valvular stenosis persists after surgery to replace the valve in almost half of the patients. No association has been found to its persistence. The main objective of this study was to evaluate the inflammatory response in patients with aortic stenosis through the determination of several biomarkers in plasma measured before and after the valvular replacement and to seek an association with the type of prosthesis used. METHODS: This is an observational study with a follow up of 6 months in subjects with severe aortic stenosis...

BACKGROUND AND OBJECTIVES: The aim of the present study is to report the early and mid-term clinical and haemodynamic results of the St Jude Medical Regent 19-mm aortic mechanical prothesis (SJMR-19). MATERIALS AND METHODS: Between January 2002 and January 2012, 265 patients with aortic valve disease underwent AVR (Aortic Valve Replacement) with a SJMR-19 (St Jude Medical Regent Nr.19). There were 51 males. Mean age was 67.5±12.72years and mean body surface area (BSA) was 1...

AIM: Patient-prosthesis mismatch (PPM) is a common occurrence in aortic valve surgery. Even the discussions about the impact of this phenomenon on the results of aortic valve surgery, the management of this problem remain one of the main topics in this kind of surgery. One of the ways of a solution is aortic annulus enlargement. The main topic of this study is to evaluate the early and longterm results of this technique in our country. METHODS: During the period January 2010 -January 2015, 641 patients performed aortic valve surgery...

OBJECTIVE: The aim of the present study is to report the early and mid-term clinical and hemodynamic results of a prospective trial investigating the clinical performance of the St. Jude Medical Regent 17 mm (SJMR-17) versus St. Jude Medical Hemodynamic Plus 17 mm (SJMHP-17). MATERIALS AND METHODS: Between January 2000 and August 2013, 20 patients (Group I) with aortic valve (AV) stenosis underwent first time AV replacement with a SJMR-17 and nine patients (Group II) underwent AV replacement with a SJMHP-17...

Valve replacement is the standard surgical treatment of diseased valves that cannot be repaired. The main goal of replacement is to exchange the diseased valve with one that has the engineering and hemodynamics as close as possible to the disease free native valve. However due to mechanical and fluid dynamic constraints all prosthetic heart valves (PHVs) are smaller than normal and thus are inherently stenotic. This represents a challenge when it comes time to replace a valve. The correct valve with the correct and matching profile has to be selected before the procedure to avoid possible complications...

OBJECTIVE: We aimed to compare early and midterm clinical and hemodynamic outcomes of 17-mm vs. 19-mm St. Jude Medical Regent valves with concomitant aortic annulus enlargement. METHODS: Between 1999 and 2012, 20 patients (group 1) underwent first-time aortic valve replacement with a 17-mm St. Jude Medical Regent valve, and 35 patients (group 2) had a 19-mm valve and concomitant aortic annulus enlargement. The mean follow-up was 81 ± 37 months (range 20-110 months)...

The design of stentless valve prostheses is intended to achieve a more physiological flow pattern and superior hemodynamics in comparison to stented valves. First - generation stentless bioprosthesis were the Prima valve, the Freestyle valve and the Toronto stentless porcine valve. The second generation of stentless valves, as the Super stentless aortic porcine valve, need only one suture line. The Sorin Pericarbon Freedom and the Equine 3F heart Valve belong to the third generation of stentless valve pericardial bioprostheses...

Aneurysms of the sinus of Valsalva (ASVs) are rare. They can be congenital or acquired through infection, trauma, or degenerative diseases. They frequently co-occur with ventricular septal defects, aortic valve dysfunction, or other cardiac abnormalities. Although unruptured ASVs are usually asymptomatic, ruptured ASVs often cause symptoms similar to those of heart failure and produce a continuous, mechanical-sounding murmur. Transsternal or transesophageal echocardiography is usually effective in detecting ASVs...

Authors report the results of a retrospective study (January 1993-December 1996) concerning 56 patients. The aim of this study was to describe epidemiology, diagnosis, evolution and treatment of rheumatic fever during childhood in the Teaching Hospital of Brazzaville. The frequency of the disease was 1.17%. There were 36 girls and 20 boys (p = 0.02). The mean age was 10 years and 8 months. Past of sore throat and recurrences of acute rheumatic fever have been notified respectively in 27 (48.2%) and 11 cases (19...

OBJECTIVE: Partial left ventriculectomy (PLV) (also known as Batista's Procedure) is a surgical procedure for treatment of dilated cardiomyopathy when cardiac transplant is contraindicated. Mitral valve replacement is needed because of mitral regurgitation as a consequence of annulus enlargement and papillary muscle resection. Bleeding and arrythmias are the main complications. METHODS: We considered for this operation a 60-year-old male patient. He suffered from valvular dilating cardiomyopathy as a consequence of mitral and aortic valve regurgitation...

The obstruction of the mechanical valve prothesis (OMVP) is a serious complication. The treatment of this complication was classically surgical. Recently, the thrombolytic treatment was introduced as an alternative approach for patients with high perioperative risk and for those in whom the mechanism of the obstruction is a recently formed thrombus. The authors report four cases of OMVP treated by a thrombolytic agent (Streptokinase, SK, Streptase). Immediate success was obtained in all theses four cases. One late recurrence with fatal issue was noted...

HISTORY AND ADMISSION FINDINGS: At the age of 55 years a now 70-year-old man had his aortic valve replaced by a prosthetic (Björk-Shiley) valve, and 11 years later a VDD pacemaker had been implanted. 18 months before the latest admission he had been hospitalized for treatment of staphylococcal endocarditis involving the aortic prothesis. At that time thrombocytopenia developed during heparin administration, diagnosed clinically and with the heparin-induced platelet activity (HIPA) test as type II heparin induced thrombocytopenia...

The Carbomedics valve prosthesis is a second generation mechanical prosthesis with a double hemi-disc. This study analysed long-term morbidity and mortality associated with this prosthesis. Between 1987 and 1996, 397 prostheses were implanted, 306 aortic, 42 mitral and 26 double replacements (3 combining a Carbomedics aortic prothesis with a mitral valve from another type) in 370 patients with a mean age of 62 (range 4 to 88 years). The global operative mortality was 7.4%. A questionnaire sent to treating cardiologists, general practitioners and patients updated the prospective data base of the cardiac surgical department...

BACKGROUND: Risk evaluation comparing the minimally invasive and standard aortic valve operations has not been studied. METHODS: Four surgeons were randomly assigned to perform the minimally invasive (L-shaped sternotomy) (group 1) or the conventional (group 2) operation in 120 patients exclusively. RESULTS: In both groups (n = 60) a CarboMedics prothesis was implanted in 90% of patients. There was no significant difference in the cross-clamping period (group 1, 60 minutes; range, 35 to 116 minutes), in the duration of extracorporal circulation (group 1, 84 minutes; range, 51 to 179 minutes) or in the time from skin-to-skin (group 1, 195 minutes; range, 145 to 466 minutes)...

Twenty six of malfunctioning valve prosthesis (one patient with two prosthesis) operated between may 1977 and may 1980 at the National Institute of Cardiology of Mexico are revised. Seventeen prosthesis were implanted in the mitral position and 10 in the aortic position. A comparative study is male between the different types of prosthesis, especially between the duramater and the Björk prosthesis. Clinical diagnosis of malfunctioning prosthesis was made in all the patients; cardiac catherization was done in 20 patients...
