RESUMO

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) has become standard therapy for aortic stenosis patients with intermediate or high operative risk. Treatment of patients with pre-existing mechanical mitral valve replacement (MVR) is challenging due to possible interference between the TAVI prosthesis and MVR. We present our single-center experience with this special patient cohort. METHODS: A total of 1960 patients underwent TAVI at our institution between 2009 and March 2018; of these, 16 patients had pre-existing mechanical MVR. Device success and adverse events were analyzed according to the Valve Academic Research Consortium (VARC)-2 criteria. Patients were followed for at least 12 months. RESULTS: Mean patient age was 81.5 ± 4.4 years. The patients had a mean logistic EuroScore of 37.1 ± 13.5% and STS score of 7.1 ± 3.2%. Successful valve deployment was achieved in all patients, peri-interventional stroke rate was 0.0%, and permanent pacemaker was implanted in 2 patients (12.5%). Two patients experienced major complications, with blockage of the MVR disc in 1 patient and annulus rupture in 1 patient. Hence, 30-day mortality was 12.5% and 1-year mortality was 25.0%. CONCLUSION: TAVI in patients with mechanical MVR is challenging and requires careful preparation and choice of TAVI device. Repositionable and retrievable devices seem to be a safer option.

RESUMO

OBJECTIVES: Although transcatheter aortic valve implantation was the treatment of choice in inoperable and high-risk patients, the effect of transcatheter aortic valve implantation relative to conventional aortic valve replacement via ministernotomy in patients with moderate surgical risk remains unclear. METHODS: We consecutively enrolled patients who underwent minimally invasive aortic valve replacements via ministernotomy (n = 1929), transapical (n = 607), and transfemoral (n = 1273) aortic valve implantations from a single center during the period from July 2009 to July 2017. Of those, we conducted a 1:1:1 propensity score matching according to 23 preoperative risk factors. RESULTS: We were able to find 177 triplets (n = 531). The median European System for Cardiac Operative Risk Evaluation II was 3.0% versus 3.4% versus 2.9%, and Society of Thoracic Surgeons Predicted Risk of Mortality was 3.2% versus 3.6% versus 3.4%, respectively. According to the Valve Academic Research Consortium 2 criteria, there were no significant periprocedural differences regarding 30-day mortality (2.3% minimally invasive aortic valve replacement vs 4.5% transapical transcatheter aortic valve implantation vs 1.7% transfemoral transcatheter aortic valve implantation, P = .34), stroke (1.1% minimally invasive aortic valve replacement vs 0.6% transapical transcatheter aortic valve implantation vs 1.7% transfemoral transcatheter aortic valve implantation, P = .84), or myocardial infarction (0.6% minimally invasive aortic valve replacement vs 0.0% transapical transcatheter aortic valve implantation vs 0.0% transfemoral transcatheter aortic valve implantation, P = .83). Both intensive care and hospitalization times were significantly longer in the transapical group. Regarding midterm survival, transapical transcatheter aortic valve implantation was associated with a tendency toward a less favorable outcome (hazard ratio, 1.48; 95% confidence interval, 0.95-2.31; P = .17) compared with minimally invasive aortic valve replacement. CONCLUSIONS: In this real-world propensity score-matched minimally invasive aortic valve replacement, transapical transcatheter aortic valve implantation, transfemoral transcatheter aortic valve implantation cohort of intermediate-risk patients, early mortality was not significantly different, whereas the rates of periprocedural complications were different depending on the approach. During follow-up, there was a tendency in the transapical transcatheter aortic valve implantation group toward a less favorable survival outcome, although there was no significant difference among the 3 groups.

RESUMO

Transapical transcatheter aortic valve implantation is a well-established alternative in patients at a high risk for conventional aortic valve replacement. We performed transapical transcatheter aortic valve implantation on an 83-year-old woman with symptomatic severe aortic stenosis. Intraoperative transoesophageal echocardiography (TOE) after transcatheter aortic valve implantation showed mild mitral regurgitation without intracardiac structural injury. In the intensive care unit, the patient gradually had haemodynamic instability; TOE revealed severe mitral regurgitation with A2 and A3 prolapse due to rupture of the posterior papillary muscle. To repair the mitral regurgitation, mitral valve replacement was performed. Preoperative TOE revealed posterior displacement of the left ventricle due to right ventricular dilatation. Computed tomography showed the insertion angle of the guidewire from the left ventricular apex to the aortic valve as 95.6° and a relatively sharp angle of guidewire through the aortic valve. In such a case, it is necessary to carefully perform the catheter procedures to prevent intracardiac structure injury; posterior papillary muscle is particularly crucial.

RESUMO

OBJECTIVES: Meta-analyses from observational and randomized studies have demonstrated benefits of off-pump surgery for hard and surrogate endpoints. In some of them, increased re-revascularization was noted in the off-pump groups, which could impact their long-term survival. Therefore, we analyzed the course of all patients undergoing isolated coronary surgery regarding the major cardiac and cerebrovascular event (MACCE) criteria. METHODS: A prospective register was taken from a high-volume off-pump center recording all anaortic off-pump (ANA), clampless off-pump (PAS-Port) and conventional (CONV) coronary artery bypass operations between July 2009 and June 2015. Propensity Score Matching was performed based on 28 preoperative risk variables. RESULTS: We identified 935 triplets (N = 2805). Compared with CONV, in-hospital mortality of both the ANA group (OR for ANA [95% CI] 0.25 [0.06; 0.83], P = 0.021), and the PAS-Port group was lower (OR for PAS-Port [95% CI] 0.50 [0.17; 1.32], P = 0.17). In the mid-term follow-up there were no significant differences between the groups regarding mortality (HR for ANA [95%-CI] 0.83 [0.55-1.26], P = 0.38; HR for PAS-Port [95%-CI] 1.06 [0.70-1.59], P = 0.79), incidence of stroke (HR for ANA 0.81 [0.43-1.53], P = 0.52; HR for PAS-Port 0.78 [0.41-1.50], P = 0.46), myocardial infarction (HR for ANA 0.53 [0.22-1.31], P = 0.17; HR for PAS-Port 0.78 [0.37-1.66], P = 0.52) or re-revascularization rate (HR for ANA 0.99 [0.67-1.44], P = 0.94; HR for PAS-Port 0.95 [0.65-1.38], P = 0.77). CONCLUSIONS: Both off-pump clampless techniques were associated with lower in-hospital mortality compared with conventional CABG. The mid-term course showed no difference with regard to the MACCE criteria between anaortic off-pump, clampless off-pump using PAS-Port and conventional CABG.

RESUMO

We performed transapical transcatheter aortic valve implantation on an 87-year-old woman with severe aortic valve stenosis. Because of the narrow left ventricular outflow tract, annular positioning of the prosthetic valve proved challenging. During positioning, the prosthetic valve was accidentally dislodged from the balloon catheter and dropped into the left ventricle. Attempted catheter retrieval was unsuccessful. We therefore converted to open surgery without delay. After aortotomy, to our surprise, the prosthesis could not be found, neither in the left ventricle nor in the ascending aorta. Transesophageal echocardiography failed to reveal the location of the missing prosthesis. Fluoroscopy finally displayed the prosthesis in the descending aorta at the level of the left atrium. We proceeded with aortic and mitral valve replacement and closed the sternum. Under fluoroscopic guidance, the prosthetic valve was secured to the wall of the abdominal aorta in an infrarenal position by dilatation with a balloon catheter. This case shows that we should be alert to septum hypertrophy or a narrow left ventricular outflow tract during transapical aortic valve implantation. In such anatomical situations, we recommend advancing the sheath of the application system directly below the annular plane and positioning the prosthesis from this point.

RESUMO

OBJECTIVES: The proportion of minimally invasive approaches is rising in cardiac surgery, in part driven by increasing patient demand. This study aimed to perform a risk-adjusted comparison of mortality, rate of stroke and perioperative morbidity of aortic valve replacement (AVR) conducted through either partial mini-sternotomy or conventional sternotomy. METHODS: Between July 2009 and July 2012, data from 984 consecutive patients undergoing isolated AVR were prospectively recorded. In 44.3% (n = 436), the less invasive partial mini-sternotomy was used. Propensity score matching was performed based on 15 preoperative risk factors to correct for selection bias. In-hospital mortality, stroke rate as well as other major complications in the minimally invasive group and conventional sternotomy group were compared in 404 matched patient pairs (total 808). RESULTS: In-hospital mortality and rate of postoperative intra-aortic balloon pump use were identical for propensity-matched patients, 1.0% (4 in each group). The rate of stroke [OR (95% confidence interval (CI)): 0.80 (0.22-2.98)], perioperative myocardial infarction [OR (95% CI): 2.00 (0.18-22.06)], low-output syndrome [OR (95% CI): 0.90 (0.37-2.22)], new onset of dialysis [OR (95% CI): 1.25 (0.49-3.17)] and re-exploration for bleeding [OR (95% CI): 0.88 (0.50-1.56)] were similar. Likewise, resource utilization (operation time, duration of stay in the intensive care unit and in-hospital stay) and valve selection (type and size) was not affected by the surgical approach either. CONCLUSIONS: AVR can be safely conducted through a partial mini-sternotomy. This approach is not associated with an increased rate of complications. However, wide CIs reflect the still prevailing statistical uncertainty in estimates, not excluding patient-relevant differences between approaches. Large trials, which also address end points, such as postoperative pain, duration of postoperative recovery and quality of life, are needed to clarify the role of minimally invasive AVR.

RESUMO

Primary cardiac tumors are rare with an incidence ranging from 0.001% to 0.03% in autopsy series. The prognosis of cardiac sarcomas remains poor because it proliferates rapidly and distant metastases are often found at diagnosis. A 47-year-old male complained of persistent cough. The chest roentgenogram was normal. Subsequent computed tomography revealed a mass in the right atrium. Echocardiography and magnetic resonance imaging confirmed also a right atrial mass (34 x 35 mm) infiltrating the atrial septum. The tumor was completely resected en bloc, including the anterior and lateral right atrial walls, the left atrial dome, and a large segment of the superior vena cava, and reconstructed the atria and superior vena cava with bovine pericardium. The tumor was histologically and immunohistochemically diagnosed as undifferentiated pleomorphic sarcoma. This type of cardiac sarcoma is very rare and usually found in the left atrium. Twenty-seven months after surgery, the patient is doing well without metastasis or local tumor recurrence.

RESUMO

Solitary fibrous tumor of the pleura is a rare mesenchymal tumor, representing less than 5% of all neoplasms associated with the pleura. A 57-year-old man had general malaise without chest symptoms for 1 month. A chest roentgenogram and computed tomography showed a giant mass in the left thorax. Although the tumor compressed the descending aorta and other mediastinal structures strongly, thereby shifting them to the right side, the patient had no symptoms except malaise. The tumor was successfully resected via two separate thoracotomies. The tumor was measured (20 cm × 19 cm × 15 cm) and weighed (2150 g). The tumor was histologically and immunohistochemically diagnosed as benign. Although SFT is benign, a long follow-up period is essential as even patients with complete resection are at risk of recurrence many years after surgery.

RESUMO

An isolated cleft of the mitral valve leaflet is rare cause of mitral regurgitation in adults. We report a successful minimally invasive mitral valve repair for severe mitral regurgitation caused by an isolated cleft of the anterior mitral leaflet. During the operation, we found a large cleft measuring 5×8 mm in the center of the anterior mitral leaflet. We closed the cleft directly and performed annuloplasty with a 30-mm Carpenter-Edwards Physio Ring (Edwards Lifesciences, Irvine, CA). The mitral valve is very well visualized with the video-assisted minimally invasive approach through the right chest.

RESUMO

Takayasu arteritis is an inflammatory disease that affects the aorta and its main branches. The dilation of the aortic root would cause aortic regurgitation (AR). We would demonstrate the dramatic change of the bioprosthesis implanted in the young woman with Takayasu arteritis, which has not been reported previously, and we believe that bioprosthesis should not be implanted easily in Takayasu arteritis.

RESUMO

OBJECTIVE: We assessed the efficacy of our newly modified technique, namely, less invasive quick replacement with rapid rewarming, for octogenarians undergoing emergency surgery for type A acute aortic dissection. METHODS: Forty-two patients with acute aortic dissection, whose average age was 81.7 +/- 2.3 years, were divided into two groups: group I consisted of 25 patients undergoing surgery with deep hypothermic circulatory arrest and selective cerebral perfusion; group II consisted of 17 recent patients who underwent less invasive quick replacement. In the latter technique, during open distal anastomosis with a rectal temperature of 28 degrees C without any cerebral perfusion, circulating blood in the cardiopulmonary bypass circuit was warmed to 40 degrees C accompanied by warming of the patient's body by a heating mat. As soon as the distal anastomosis was completed, rapid rewarming was initiated by 40 degrees C blood perfusion. RESULTS: The durations of cerebral protection (group I, 75.8 minutes, vs group II, 18.8 minutes), cardiopulmonary bypass (I, 201.2, vs II, 84.4 minutes), and overall operation (I, 425.6, vs II, 148.6 minutes) were significantly shorter in group II. In group I, 5 patients had complications of cerebral damage and 5 required re-exploration for bleeding, 7 had pneumonia, 6 required hemodialysis for renal failure, and the hospital mortality rate was 24% (6 patients). On the other hand, no such complications or mortality were observed in group II (P < .0291). Postoperative hospital stay was significantly shorter for the patients in group II than in group I (13.2 days vs 33.7 days; P < .0001). CONCLUSION: Less invasive quick replacement is safe and effective. It should be a standard surgical technique for octogenarians with type A acute aortic dissection.

RESUMO

OBJECTIVE: The number of octogenarians undergoing emergency surgery is increasing and may negate the impact of the beneficial advances. The aim of this study was to review octogenarians with type A acute aortic dissection and assess the prognosis. METHODS: Fifty-eight patients with acute aortic dissection, whose average age was 83.2 years, were divided into 2 groups: Group I comprised 30 patients who underwent emergency surgery, and group II comprised 28 patients who were treated conservatively. We compared the 2 groups in terms of mortality and morbidity. RESULTS: In group I, postoperative hospital mortality was 13.3% (4 patients). In group II, 17 patients (60.7%) died in the hospital. In group I, although emergency aortic replacement was successfully completed, 5 patients became bedridden after surgery and 2 patients died of pneumonia or stroke in the early stages of institutional care. Thirteen patients in group I died of malignancies, abdominal aortic rupture, traffic accident, heart failure, or late-stage senility in later phase. There was no difference in actuarial survivals at 5 years, which were 48.5% in group I and 35.4% in group II. CONCLUSION: Emergency surgery for octogenarians with acute aortic dissection showed acceptable mortality. However, families had to take responsibility for patients who experienced unconsciousness, had dementia, or became bedridden. It is important to have consensus between the family and surgeons about emergency surgical treatment for octogenarians.

RESUMO

A 64-year-old man was referred to our hospital due to dyspnea and fever. The chest computed tomogram revealed a 60-mm aneurysm of the brachiocephalic artery with mural thrombus. The aneurysm of the brachiocephalic artery and the right subclavian artery were exposed through only median sternotomy. Cardiopulmonary bypass with synchronized pulsatile perfusion was established with the ascending aorta and bi-caval cannulation. A mean arterial pressure was kept at between 60 and 70 mmHg with the unloaded beating heart. Mild hypothermia was induced (blood temperature 27 degrees C, nasopharyngeal temperature 32 degrees C). The brachiocephalic artery, right carotid artery, and right subclavian artery were clamped when nasopharyngeal temperature was 32 degrees C after decreasing blood temperature to 27 degrees C. After opening the aneurysm, the mural thrombus and calcified aneurysmal wall were removed. First, an ascending aorta to the right common carotid artery bypass was performed using a 16-8 mm Y- prosthetic graft with side-clamp forceps. After the anastomosis, the right side cerebral perfusion was restarted and the patient was rewarmed. Then the right subclavian artery was anastomosed in an end-to-end fashion. The duration of the right side cerebral circulatory arrest was 30 minutes. The patient left hospital seven days after the operation.

RESUMO

A 66-year-old man with acute fulminant myocarditis was supported by a left ventricular assist device (LVAD) for 22 days, and successfully recovered from severe heart failure. Prior to this, he was treated using percutaneous cardiopulmonary support (PCPS) for five days. However, cardiac function was not recovered, so we conducted implantation of the LVAD. It is essential to make an immediate decision regarding LVAD implantation to save patients with fulminant myocarditis.

RESUMO

An aortoesophageal fistula is uncommon, but almost always fatal. We report a case of an aortoesophageal fistula that developed after stent dilation for an esophageal stricture caused by benign esophagitis. As soon as esophageal hemorrhaging was identified by endoscopy, the patient was transferred to the operating theater; however, the uncontrollable and massive bleeding resulted in pulseless shock. The digestive surgeon put side-clamps on the descending aorta and esophagus and transferred the patient to our hospital. We identified an aortoesophageal fistula, 3.0 mm in diameter, in the descending aorta, and performed a graft replacement of the descending aorta and esophagectomy. It was immediately evident that the edge of the stent had been sticking into the aortic wall, which had caused the fistula. To our knowledge, this is the first report of successful surgical treatment of an aortoesophageal fistula caused by esophageal stent dilatation.

RESUMO

PURPOSE: The Starr-Edwards ball valve was first applied clinically in 1960. In our hospital, this valve has been used since 1963, and some patients have been followed up for 30 years or more. Based on our experience, therapeutic strategies included revalve replacement as a preventive procedure in the absence of valve-related complications. In this study, we investigated whether prophylactic reoperation after valve replacement with the Starr-Edwards ball valve is appropriate. PATIENTS AND METHODS: Of 58 patients in our institute who underwent mitral valve replacement with the Starr-Edwards ball valve, 12 underwent revalve replacement. Of these 12, the subjects of the present study were 4 patients who underwent prophylactic revalve replacement. RESULTS: The mean postoperative follow-up of the 4 patients was 31.0+/-3.7 years. There were no operative deaths or postoperative complications. On examination of the extirpated Starr-Edwards valves, cloth wear was observed in all 4 patients. Although there was no influence on the range of ball motion, they showed the entity of "thrombus/pannus." CONCLUSION: In this study, all of the patients showed cloth wear in the absence of complications. Therefore we consider that prophylactic reoperation after valve replacement with the Starr-Edwards valve should be performed to prevent complications.

RESUMO

BACKGROUND: The long-term outcome of medical treatment in patients with type B acute aortic dissection (BAD) was assessed and predictors of early in-hospital death were investigated, as well as the need for surgical intervention. METHODS AND RESULTS: In the past 11 years, 180 patients were admitted to hospital and medically treated at the time of onset. If the maximum diameter of the dissected aorta exceeded 60 mm, or rapid enlargement or vital organ ischemia were identified, early or elective surgery was performed. Emergency operation was required in 7 patients. Elective surgery was required for 31 patients (19.1%). The operation-free rate was 76.0% at 10 years. Actuarial survival rate was 89.4% at 5 years and 71.8% at 10 years. Multivariate analysis indicated that refractory hypertension (odds ratio (OR), 4.08, 95% confidence interval (CI), 3.06-21.44, p=0.0434) and rupture (OR 5.87, 95% CI, 2.21-9.12, p=0.0154) were predictors of early hospital mortality. The only significant predictor for elective surgery was a maximum diameter exceeding 40 mm at the time of onset (OR 13.4, 95% CI, 1.93-6.89, p=0.0003). CONCLUSIONS: Medical treatment for BAD produced good results. Strict control of blood pressure is important for patients with a dissected aortic diameter exceeding 40 mm at the time of onset.
