Surgical versus transcatheter aortic valve replacement in low-risk patients: A long-term propensity score-matched analysis.

BACKGROUND: Recent studies suggest the use of transcatheter aortic valve implantation (TAVI) as an alternative to surgical aortic valve replacement (SAVR) in lower risk populations, but real-world data are scarce. METHODS: Single-center retrospective study of patients undergoing SAVR (between June 2009 and July 2016, n = 682 patients) or TAVI (between June 2009 and July 2017, n = 400 patients). Low surgical risk was defined as EuroSCORE II (ES II) < 4% for single noncoronary artery bypass graft procedure. TAVI patients were propensity score-matched in a 1:1 ratio with SAVR patients, paired by age, New York Heart Association class, diabetes mellitus, chronic obstructive pulmonary disease, atrial fibrillation, creatinine clearance, and left ventricular ejection fraction < 50%. RESULTS: A total of 158 patients (79 SAVR and 79 TAVI) were matched (mean age 79 ± 6 years, 79 men). TAVI patients had a higher incidence of permanent pacemaker implantation (0% vs. 19%, p < 0.001) and more than mild paravalvular leak (4% vs. 18%, p = 0.009), but comparable rates of stroke, major or life-threatening bleeding, emergent cardiac surgery, new-onset atrial fibrillation, and need for renal replacement therapy. Hospital length-of-stay and 30-day mortality were similar. At a median follow-up of 4.5 years (IQR 3.0-6.9), treatment strategy did not influence all-cause mortality (HR 1.19, 95% CI 0.77-1.83, log rank p = 0.43) nor rehospitalization (crude subdistribution HR 1.56, 95% CI 0.71-3.41, p = 0.26). ES II remained the only independent predictor of long-term all-cause mortality (adjusted HR 1.40, 95% CI 1.04-1.90, p = 0.029). CONCLUSION: In this low surgical risk severe aortic stenosis population, we observed similar rates of 30-day and long-term all-cause mortality, despite higher rates of permanent pacemaker implantation and more than mild paravalvular leak in TAVI patients. The results of this small study suggest that both procedures are safe and effective in the short-term, while the Heart Team remains essential to assess both options on the long-term.

Complete surgical revascularization: Different definitions, same impact?

BACKGROUND: There are several different definitions of complete revascularization on coronary surgery across the literature. Despite the importance of this definition, there is no agreement on which one has the most impact. The aim of this study was to evaluate which definition of complete surgical revascularization correlates with early and late outcomes. METHODS: All consecutive patients submitted to isolated CABG from 2012 to 2016 with previous myocardial scintigraphy were evaluated. EXCLUSION CRITERIA: emergent procedures and previous cardiac surgery procedures. The population of 162 patients, follow-up complete in 100% patients; median 5.5; IQR: 4.4-6.9 years. Each and all of the 162 patients were classified as complying or not with the four different definitions: numerical, functional, anatomical conditional, and anatomical unconditional. Perioperative outcome: MACCE; long-term outcomes: survival and repeat revascularization. Univariable and multivariable analyses were developed to detect predictors of outcomes. RESULTS: Complete functional revascularization was a predictor of increased survival (HR: 0.47; CI 95: 0.226-0.969; p = .041). No other definitions showed effect on follow-up mortality. Age and cardiac dysfunction increased long-term mortality. The definition of complete revascularization did not have an impact on MACCE or the need for revascularization CONCLUSIONS: A uniformly accepted definition of complete coronary revascularization is lacking. This study raises awareness about the importance of viability guidance for CABG.

Cold Agglutinins and Cardiac Surgey: a Case Report.

Cold agglutinins (CA) are autoantibodies whose clinical significance depends upon titer and thermal amplitude. Patients, which undergo cardio-pulmonary bypass and especially hypothermic cardioplegia myocardial protection, represent a challenge regarding operative management, as tissue temperature should be maintained above the threshold of agglutination. We report on a case in which the presence of CA was discovered during elective aortic valve replacement surgery, and managed with normothermic cardiopulmonary bypass and continuous retrograde warm blood cardioplegia administration.

Dabigatran reversal with idarucizumab in a patient undergoing heart transplantation: first European report.

BACKGROUND: Dabigatran is a direct thrombin inhibitor with a favorable effectiveness and safety profile when compared to vitamin K antagonists, both in randomized trials and real world registries of atrial fibrillation patients. Yet, physicians' fear of high bleeding risk scenarios in daily clinical practice still precludes a more widespread use of oral anticoagulation. We hereby report a successful case of dabigatran reversal with the novel monoclonal antibody fragment idarucizumab in a patient undergoing heart transplantation. CASE PRESENTATION: A 45-year old male patient on dabigatran for atrial fibrillation thromboprophylaxis was enlisted for heart transplantation due to end-stage ischemic heart failure. Upon donor availability and suitability and following the last intake of the drug 12 h previously, activated partial thromboplastin time was measured and found to be elevated. After general anesthesia and before extracorporeal circulation, idarucizumab was administered as two boluses of 2.5 g. Orthotopic heart transplantation ensued under full heparinization and cardiopulmonary bypass. Total chest tube output was 1125 mL after 3 days and 4 units of fresh frozen plasma and one platelet pool were administered in the operating room without further need for blood products. The post-operative period was uneventful. CONCLUSIONS: Idarucizumab was associated with an effective hemostasis in the setting of heart transplantation. Dabigatran may be considered as an alternative to vitamin K antagonists in heart transplant candidates with an indication for oral anticoagulation.

Transcatheter tricuspid valve-in-valve replacement: one-year results : Alternative to surgery in high-risk patients.

Although rheumatic heart disease is becoming uncommon in industrialized countries, its global burden is still significant. We report the case of a 70-year-old male with rheumatic heart disease, who underwent 4 previous heart valve replacement surgeries, and presented to our hospital with refractory heart failure (NYHA functional class IV) due to severe stenosis of a previously implanted tricuspid bioprosthesis. The Heart Team deemed the patient as inoperable/high-risk for surgery. As an alternative, a transcatheter tricuspid valve-in-valve replacement was decided upon and later executed through the right femoral vein, with the insertion of an Edwards SAPIEN XT 29 no. (Edwards Lifesciences, Irvine, CA, USA) through the inferior vena cava, towards the RV, followed by direct implantation in the tricuspid bioprosthesis (valve-in-valve), under rapid pacing, without complications. A substantial clinical and echocardiographic improvement was noted after the procedure and the patient was subsequently discharged in NYHA functional class II. These favourable outcomes persisted through the 1-year follow-up period. This case report adds to the current body of evidence that tricuspid valve implantation stands as a viable and reliable alternative in the treatment of degenerated bioprosthesis in high-surgical-risk patients.

Trauma: An Unusual Cause of Endocarditis.

INTRODUCTION: Infective endocarditis (IE) remains a dangerous condition with considerable associated mortality. Usual risk factors for IE include the presence of a prosthetic heart valve, structural or congenital heart disease, intravenous drug use, and a recent history of invasive procedures. METHODS: The authors describe the case report of a patient with IE having trauma as an unusual risk factor. RESULTS: A 33-year old male patient was referred to our department due to infective endocarditis. The patient had a fever of unknown origin for 15 days before going to the emergency department. After admission it was identified by transthoracic echocardiography a 14mm posterior abscess of the aortic valve provoking major aortic regurgitation with moderate LV dysfunction. After careful evaluation of the clinical history it was found that the patient had a known bicuspid aortic valve with follow-up since the age of 14. All other usual risk factors for IE were excluded, including intravenous drug use and recent history of invasive procedures. The only relevant previous event was a traumatic haemathoma in his left jaw caused by a working accident with an iron beam in a construction site as the patient is a civil engineer. Vancomycin plus gentamicin were empirically started after blood cultures taken. The isolated infective agent was Staphylococcus lugdunensis methicillin sensitive and the antibiotherapy was de-escalated to flucloxacilin plus gentamicin. Due to cardiac dysfunction the patient was submitted to cardiac surgery on the fourth day of directed antibiotic therapy and a replacement of the aortic valve by a mechanical prosthetic valve and closure of the abscess with bovine pericardial patch was performed. The valve sent to microbiology evaluation showed the same infective provocative agent. The patient had a good clinical and laboratorial recovery completing the 42-day antibiotic scheme. After antibiotherapy period completion, echocardiography was repeated and the abscess found was larger then the previous one, presenting itself like an aortic pseudo aneurysm. The patient was resubmitted to surgery with re-closure of the initial abscess with autologous pericardial patch and replacement of the prosthetic mechanical valve for an undersized one. The patient was discharger clinically well, having a complete normal life at the moment. CONCLUSION: This clinical case illustrates trauma as an unusual cause of endocarditis and emphasizes the importance of a detailed clinical history.

Diagnostic Challenges in Chronic Constrictive Pericarditis.

INTRODUCTION: Chronic constrictive pericarditis (CCP) is a disease that has multiple possible causes and is associated with variable clinical findings, depending on its severity. It develops insidiously, and in many cases, particularly in developed countries, no antecedent diagnosis can be found. These cases are termed idiopathic. Tuberculosis is the leading cause of constrictive pericarditis in developing nations but represents only a small minority in developed countries. METHODS: Here the authors describe two different case reports where tuberculosis was the probable cause of CCP. RESULTS: A 21-year-old man born in Cape Verde living in Europe for 4 years and a 24-year-old man born in Guiné Bissau were both admitted due to intense precordial pain and syncope after exertion. Interestingly both had fatigability, dyspnea, chest discomfort and palpitations on exertion, as well as progressive involuntary weight loss and decubitus cough. On physical examination they had tachycardia, jaundice, cachexia, elevated jugular venous pressure, hepatomegaly and ascites. Both electrocardiograms showed prominent P waves and chest X-ray showed bilateral pulmonary interstitial infiltrates and enlargement of the right cavities. Analytically, elevated bilirubin, leukopenia and thrombocytopenia was also found in both. Echocardiography revealed findings, in both cases, compatible with CCP including less common signs as annulus reversus and annulus paradoxus. Thoraco-abdomino-pelvic CT from both patients revealed chronic liver disease with congestion, pleural effusion, pericardial calcifications, ascites and massive mediastinal and abdominal adenopathies. Blood cultures and IGRA test were negative. However, given the presumptive diagnosis of tuberculosis (TB), anti-TB therapy was started. Despite the diagnosis of "end-stage" CCP with very high operative risk multidisciplinary team decided after informed consent, to perform total anterior pericardiectomy, that occurred without complications. Pericardial and mediastinal biopsies, pericardial/pleural fluid cultures/ immune-phenotyping were inconclusive. Anti- tuberculosis therapy was maintained. After surgery, the patients had a remarkable clinical improvement (NYHA I) that persisted in 6- month follow-up. CONCLUSION: These two case reports illustrate that despite the markedly elevated operative risk of pericardiectomy in "end-stage" forms of disease after patients informed consent must be a considered option. The other point to consider is that, despite rare, tuberculosis still is a possible diagnosis to consider in CCP in Portugal.

Pulmonary Hypertension in Valvular Heart Disease Surgery: Risk and Prognosis.

INTRODUCTION: Left heart disease is the most common cause of pulmonary hypertension (PH), and when present is associated with higher surgical risk. OBJECTIVES: Analyze the effect of PH severity on morbidity, early and late mortality in patients with pulmonary artery systolic pressure (PASP) over 30mmHg that underwent valvular heart surgery. METHODS: Retrospective observational study including all patients with PH, defined as PASP>30 mmHg that underwent isolated valvular heart surgery, between 2007 and 2016. Exclusion criteria were: active endocarditis, congenital heart disease, transcatheter aortic valve implantation, reoperations and emergent surgery. The study population included 607 patients with a mean age of 69.6 years and a mean PASP of 52.5 mmHg. Mean follow-up for all-cause mortality was 4.4(0-11) years in 99.7% of patients. MACCE (Major Adverse Cardiac and Cerebrovascular event) was defined as at least one of the following: in-hospital mortality, stroke, post-operative myocardial infarction, severe arrhythmia or multiple organ failure. PASP was evaluated as a continuous variable. Simple and multivariable logistic regression was performed to evaluate the in-hospital mortality and MACCE. Cox regression was used for long term follow-up and one-sample log-rank test for comparison with age adjusted general population. RESULTS: The in-hospital mortality was 3.2% and PASP was an independent predictor on univariable analysis (OR:1.06; 95%CI:1.03- 1.09; p<0.001). On multivariable logistic regression PH remains an independent predictor of in- -hospital mortality (OR:1.08; 95%CI:1.04-1.12; p<0.001) in addition to age (OR:1.08; 95%CI:1.01-1.17; p=0.044). MACCE was observed in 11.4% and PASP was an independent predictor on univariable analysis (OR:1.03; 95%CI:1.01- 1.04; p<0.001). On multivariable logistic regression PASP remains an independent predictor of MACCE (OR:1.02; 95%CI:1.01-1.04; p=0.011) as well as hemodialysis (OR:7.16; 95%CI:1.73-29.63; p=0.007). The independent predictors of long term mortality were male gender (p=0.011), older age (p<0.001), higher body mass index (p=0.013), urgent surgery (p=0.027), pulmonary disease (p=0.042) and more than one valve procedure (p=0.004 for 2 valves and p=0.006 for 3 valves). PASP was not an independent predictor of long term mortality (p=0.142). Compared with an age adjusted general population, patients with PH had a significantly lower survival rate(p<0.001), more evident 4 years after the procedure. CONCLUSIONS: Higher PASP is a risk factor for in-hospital mortality and MACCE, but there was no significant impact on long term mortality.

Elective and urgent coronary surgery in octogenarians.

OBJECTIVES: To analyze the influence of surgical myocardial revascularization on early and late mortality in octogenarians and compare the survival rates with age adjusted general population. METHODS: Between 2007 and 2014, 182 octogenarian patients underwent elective or urgent coronary artery bypass grafting surgery. Logistic regression was performed to evaluate the in-hospital mortality predictors. The comparison of long term survival between our population and age adjusted general population was made using one-sample log-rank test. RESULTS: The in-hospital mortality was 4,4% and its predictors on univariable analysis were non sinus rhythm (p=0,001), acute coronary syndrome less than 7 days prior to surgery (p=0,021), ejection fraction less than 50% (p=0,04) and the need for conversion to on pump surgery (p=0,04). On multivariate logistic regression non sinus rhythm and acute myocardial infarction less than 7 days before surgery were independent predictors of in-hospital mortality. Follow-up at one-year showed survival rate of 86,2% and at five years 58,4%. There was no significant difference in survival rates between the study group and the age adjusted standard population (p=0,96). The group was divided in two groups: (1) complete revascularization and (2) incomplete revascularization. There was no significant difference in survival (p=0,32 and p=0,19, respectively) compared to the age adjusted standard population. CONCLUSIONS: Coronary artery bypass grafting in octogenarians is safe and has an important impact on long term survival, with five-year survival being similar to the age adjusted standard population.

Objetivos: Analisar o impacto da revascularização miocárdica cirúrgica na mortalidade precoce e tardia em octogená- rios e comparar a sobrevida com a população geral ajustada para a idade. Métodos: Entre 2007 e 2014, 182 octogenários foram submetidos a cirurgia de revascularização miocárdica eletiva ou urgente. Utilizou-se regressão logística para avaliar os preditores de mortalidade intra-hospitalar. A comparação da sobre- vivência a longo prazo entre a população em estudo e a população ajustada para a idade efetuou-se com o teste one sample log-rank. Resultados: A mortalidade intra-hospitalar foi 4,4% e os seus preditores, na análise univariável, foram ritmo não sinusal (p=0,001), síndrome coronário agudo menos de 7 dias antes da cirurgia (p=0,021), fração de ejeção menos de 50% (p=0,04) e conversão em cirurgia on pump (p=0,04). Na análise multivariada, o ritmo não sinusal e síndrome coronário agudo menos de 7 dias antes da cirurgia foram preditores independentes de mortalidade intra-hospitalar. No seguimento a um ano a sobrevivência foi de 86,2% e a cinco anos de 58,4%. Não se verificou diferença significativa na sobrevivência entre o grupo de estudo e a população geral ajustada para a idade (p=0,96). A população em estudo foi dividida em dois grupos: (1) revascula- rização completa e (2) revascularização incompleta. Não se verificou diferença significativa (p=0,32 e p=0,19, respetivamente) quando comparados com a população geral ajustada para a idade. Conclusão: A cirurgia de revascularização miocárdica em octogenários é segura e tem um importante impacto na sobrevida a longo prazo, com sobrevivência a cinco anos semelhante à população geral ajustada para a idade.

Aortic coarctation repair in the adult.

Aortic coarctation can be repaired surgically or percutaneously. The decision should be made according to the anatomy and location of the coarctation, age of the patient, presence of other cardiac lesions, and other anatomic determinants (extensive collaterals or aortic calcification). This article reviews the different therapeutic options available, explaining the differences between children and adults, describing different approaches to the same disease, exemplified by three cases of nonclassic surgical approach and one percutaneous treatment.

[SPCCTV and SPC Recommendations Related to the Waiting Times for Cardiac Surgery]. / Recomendações da Sociedade Portuguesa de Cirurgia Cardiotorácia e Vascular (SPCCTV) e da Sociedade Portuguesa de Cardiologia (SPC) sobre os Tempos de Espera para Cirurgia Cardíaca.

Appointed jointly by the Portuguese Society for Cardiothoracic and Vascular Surgery (SPCCTV) and by the Portuguese Society of Cardiology (SPC), the Working Group related to the Waiting Times for Cardiac Surgery was created with the aim of developing practical recommendations about clinically acceptable waiting times for the three critical phases of the care of adults with a cardiac disease that require surgery or an intervention: cardiology appointments; diagnostic process and invasive therapy. Cardiac surgery has its own characteristics, not comparable to other surgical specialties and, therefore, it is important to reduce its maximum waiting times and, also, increase the efficacy of the systems which are responsible to monitor and trace the patient. The information given in this document was based, mostly, in available clinical information. The methodology used to establish the criteria was based on studies regarding disease's natural history, clinical studies that compared medical treatment with intervention, retrospective and prospective analysis of patients included on a waiting list, and experts or working groups' opinions. After this first step, marked by this publication, the SPCCTV and the SPC PSC should be considered as natural interlocutors about this matter and they are committed to decisively contribute to the definition of operational strategies through the adaption of the clinical evidence with reality and with the available resources.

Cardiac magnetic resonance patterns of left ventricular remodeling in patients with severe aortic stenosis referred to surgical aortic valve replacement.

Left ventricular (LV) hypertrophy is a common finding in patients with severe aortic stenosis (AS). Cardiac magnetic resonance (CMR) is the gold-standard technique to evaluate LV remodeling. Our aim was to assess the prevalence and describe the patterns of LV adaptation in AS patients before and after surgical aortic valve replacement (AVR). Prospective study of 130 consecutive patients (71y [IQR 68-77y], 48% men) with severe AS, referred for surgical AVR. Patterns of LV remodeling were assessed by CMR. Besides normal LV ventricular structure, four other patterns were considered: concentric remodeling, concentric hypertrophy, eccentric hypertrophy, and adverse remodeling. At baseline CMR study: mean LV indexed mass: 81.8 ± 26.7 g/m2; mean end-diastolic LV indexed volume: 85.7 ± 23.1 mL/m2 and median geometric remodeling ratio: 0.96 g/mL [IQR 0.82-1.08 g/mL]. LV hypertrophy occurred in 49% of subjects (concentric 44%; eccentric 5%). Both normal LV structure and concentric remodeling had a prevalence of 25% among the cohort; one patient had an adverse remodeling pattern. Asymmetric LV wall thickening was present in 55% of the patients, with predominant septal involvement. AVR was performed in 119 patients. At 3-6 months after AVR, LV remodeling changed to: normal ventricular geometry in 60%, concentric remodeling in 27%, concentric hypertrophy in 10%, eccentric hypertrophy in 3% and adverse remodeling (one patient). Indexes of AS severity, LV systolic and diastolic function and NT-proBNP were significantly different among the distinct patterns of remodeling. Several distinct patterns of LV remodelling beyond concentric hypertrophy occur in patients with classical severe AS. Asymmetric hypertrophy is a common finding and LV response after AVR is diverse.

Procedural success in transaxillary transcatheter aortic valve implantation according to type of transcatheter heart valve: results from the multicenter TAXI registry.

BACKGROUND: Transaxillary (TAx) transcatheter aortic valve implantation (TAVI) is a preferred alternative access in patients ineligible for transfemoral TAVI. AIMS: This study used the Trans-AXillary Intervention (TAXI) registry to compare procedural success according to different types of transcatheter heart valves (THV). METHODS: For the TAXI registry anonymized data of patients treated with TAx-TAVI were collected from 18 centers. Acute procedural, early and 1-month clinical outcomes were adjudicated in accordance with standardized VARC-3 definitions. RESULTS: From 432 patients, 368 patients (85.3%, SE group) received self-expanding (SE) THV and 64 patients (14.8%, BE group) received balloon-expandable (BE) THV. Imaging revealed lower axillary artery diameters in the SE group (max/min diameter in mm: 8.4/6.6 vs 9.4/6.8 mm; p < 0.001/p = 0.04) but a higher proportion of axillary tortuosity in BE group (62/368, 23.6% vs 26/64, 42.6%; p = 0.004) with steeper aorta-left ventricle (LV) inflow (55° vs 51°; p = 0.002) and left ventricular outflow tract (LVOT)-LV inflow angles (40.0° vs 24.5°; 0.002). TAx-TAVI was more often conducted by right sided axillary artery in the BE group (33/368, 9.0% vs 17/64, 26.6%; p < 0.001). Device success was higher in the SE group (317/368, 86.1% vs 44/64, 68.8%, p = 0.0015). In logistic regression analysis, BE THV were a risk factor for vascular complications and axillary stent implantation. CONCLUSIONS: Both, SE and BE THV can be safely used in TAx-TAVI. However, SE THV were more often used and were associated with a higher rate of device success. While SE THV were associated with lower rates of vascular complications, BE THV were more often used in cases with challenging anatomical circumstances.

Understanding cardiac myxoma recurrence: a case report.

Recurrence of cardiac myxoma is a rare condition, observed in about 3% of patients in sporadic cases, although it is more frequent in familial ones. Several mechanisms have been proposed to explain such recurrence, and the importance of increased vascularization as a facilitating feature is the subject of debate. The authors report the case of a non-familial right atrial myxoma, unusual for both its histopathology and recurrence.

Marfan syndrome with ascending aortic aneurysm: value of cardiac computed tomography.

We report the case of a 40-year-old man with known Marfan syndrome who presented with severe aortic valve regurgitation secondary to significant aortic root dilatation. To rule out coronary artery disease and to evaluate the rest of the thoracic aorta before surgery, cardiac computed tomography (CT) was performed. A brief review of the literature shows how cardiac CT can, in selected cases, rule out coronary artery disease before non-coronary cardiothoracic surgery.

Repair of a gigantic ascending aortic pseudoaneurysm - A challenging approach.

Aortic pseudoaneurysms can be a potentially fatal, yet rare, complication of heart surgery. Surgery is indicated but is high risk during sternotomy. Therefore, careful planning is required. We report the case of a 57-year-old patient who underwent heart surgery twice in the past and who presented with an ascending aortic pseudoaneurysm. A successful repair of the pseudoaneurysm was performed under deep hypothermia, left ventricular apical venting, periods of circulatory arrest and endoaortic balloon occlusion.

Infective Endocarditis: A Prospective Registry Of Surgical Lesions.

INTRODUCTION: Infective endocarditis morbidity and mortality remains high. Surgery is performed in about half of endocarditis cases, being the ideal setting to evaluate endocarditis lesions. The aim of this study was to register and describe endocarditis lesions found during surgery; find predictors of morbidity and mortality and correlate lesions found in echocardiogram vs. surgery. MATERIALS AND METHODS: One hundred consecutive patients with endocarditis lesions seen during surgery were included between June 2014 and August 2018. Pathological lesions were coded prospectively using a coding form published by Pettersson et al. Other data were collected retrospectively. RESULTS: Prosthetic endocarditis accounted for 23% of cases. Embolic events had occurred in 41% of cases, mainly to the brain (22%). The most frequent lesions found in echocardiogram were vegetations (77%). Vegetations and valve integrity anomalies were the main lesions described during surgery (70% and 71% respectively). Invasion was present in 39% of patients. In-hospital mortality was 9%. In univariable analysis, predictors of early mortality included chronic kidney disease (P= .005), prosthetic valve endocarditis (P <.001), EuroSCORE II (P <.001) and valve integrity anomalies (P=.016). Predictors of embolic events included aortic valve vegetations seen during surgery (P= .026). Sensitivity and specificity of echocardiogram findings for identification of vegetations were 84% and 40%, for valve integrity anomalies 42% and 97% and for invasion 54% and 95%, respectively. CONCLUSIONS: Diversity of lesions found in endocarditis precludes obtaining significant predictors of morbidity or mortality with small numbers of patients. Echocardiogram lacks sensitivity for valve integrity anomalies and invasion but is highly specific.

Uncommon acquired Gerbode defect following extensive bicuspid aortic valve endocarditis.

Gerbode defect is a rare type of left ventricle to right atrium shunt. It is usually congenital in origin, but acquired cases are also described, mainly following infective endocarditis, valve replacement, trauma or acute myocardial infarction. We report a case of a 50-year-old man who suffered an extensive and complex infective endocarditis involving a bicuspid aortic valve, the mitral-aortic intervalvular fibrosa and the anterior leaflet of the mitral valve. After dual valve replacement and annular reconstruction, a shunt between the left ventricle and the right atrium--Gerbode defect, and a severe leak of the mitral prosthesis were detected. Reintervention was performed with successful shunt closure with an autologous pericardial patch and paravalvular leak correction. No major complications occurred denying the immediate post-surgery period and the follow-up at the first year was uneventful.
