The increase of end-diastolic pressure reduces the possibility of a recovery and may cause severe pulmonary edema. In this study, we evaluate our results after implantation of VA-ECMO and Transapical Left Ventricular Vent (TLVV) as a bridge to recovery, heart transplantation or long-term left ventricular assit devices (LVAD). From 2011 to 2014, 24 consecutive patients with profound cardiogenic shock were supported by peripheral VA-ECMO as bridge to decision. In all cases, TLVV was implanted after a mean period of 12.2 ± 3.4 hours through a left mini-thoracotomy and connected to the venous inflow line of the VA-ECMO. Thirty-day mortality was 37.5% (9/24). In all patients, hemodynamics improved after TLVV implantation with an increased cardiac output, mixed venous saturation and a significant reduced heart filling pressures (p < .05). Recovery of the c...

The evolution of mechanical circulatory support suggests that current advanced cardiovascular life support protocols no longer represent the highest standard of care at competitive sporting events with large spectator numbers. Extracorporeal life support (ECLS) improves resuscitation strategies and offers a rescue therapy for refractory cardiac arrest that can no longer be ignored. We present our operational experience of an out-of-hospital ECLS cardiopulmonary resuscitation team at an international sporting event.

Papillary fibroelastoma (PFE) represents only 16% of the benign cardiac tumor and approximately 15% of these are located on tricuspid valve. Materials and Methods Over a period of 22 years (1999-2021) we observed 75 pts with cardiac tumors at our Center over 9650 pts operated on but only one case of a tricuspid valve PFE in a 69-year-old patient. Trans-thoracic echocardiography demonstrated a mobile mass (20 x 10 mm), adhering to the atrial side of the septal leaflet of the tricuspid valve of unknown origin. In consideration of the mobility of the mass and the consequent high embolic risk, surgical removal was made. Patient underwent surgery through a median sternotomy on CPBP. A "gelatinous" mass adhering to the tricuspid leaflet was found and completely removed. The postoperative course was uneventful. The pathological diagnosis was PFE. Conclusions. PFE of the tricuspid valve is rare entities being in most cases found incidentally. In our experience the incidence of this tumor in this location is 1/10000 cases of cardiac surgery. Although most patients are asymptomatic, surgical treatment is nevertheless recommended in consideration of the high embolic risk.

Left posterolateral thoracotomy with the outflow graft connected to the descending aorta with or without CPB. This approach is more frequently used in case of reoperations to avoid re-sternotomy. Minimally invasive left mini-thoracotomy (with or without CPB).

During approximately one month, the patient was treated with double pericardiocentesis for cardiac tamponade and the last of them was interrupted for the suspect of left ventricular puncture due to aspiration of arterial blood from the needle used for pericardiocentesis. Considering the suspect of infective pleuropericarditis and patient’s symptoms, a surgical drainage of the pericardial effusion was performed via right thoracotomy. The echocardiography and CT-scan performed after right thoracotomy showed only a mild pericardial effusion. Fifteen days later, the patient suffered from congestive heart failure and fever. The echocardiography and CT-scanning which were performed urgently, showed a large pseudoaneurysm (approx. 26 mm = 36 mm) of the apex of the left ventricle. Ventriculography confirmed the presence of the pseudoaneurysm in connection with the left ventricular apex. Exclusion of ...

Reoperation is challenging but conservative therapy is not effective. The aim of this study was to assess short- and midterm outcomes of patients reoperated on for Bentall-related endocarditis. METHODS Seventy-three patients with Bentall procedure-related endocarditis were recorded in the Italian registry. The mean age was 57 ± 14 years and 92% were men; preoperative comorbidities included hypertension (45%), diabetes (12%) and renal failure (11%). The logistic EuroSCORE was 25%; the EuroSCORE II was 8%. RESULTS Preoperatively, 12% of the patients were in septic shock; left ventricular-aortic discontinuity was present in 63% and mitral valve involvement occurred in 12%. The most common pathogens were Staphylococcus aureus (22%) and Streptococci (14%). Reoperations after a median interval of 30 months (1–221 months) included a repeat Bentall with a biocondui...

Echocardiography is an invaluable tool to optimize medical treatment and pump settings and also for troubleshooting residual heart failure. Little is known about the echocardiographic evaluation of hemodynamic status in HVAD patients. Right heart catheterization and Doppler echocardiography were performed in 35 HVAD patients. Echocardiography-estimated RAP (eRAP) was assessed using inferior vena cava diameter, hepatic venous flow analysis, and tricuspid E/e' ratio. Echocardiography-estimated LAP was assessed using E/A ratio, mitral E/e' ratio, and deceleration time. eRAP and estimated LAP significantly correlated with invasive RAP and LAP (respectively, r = 0.839, p < 0.001, and r = 0.889, p < 0.001) and accura...

Pump replacement for thrombosis is a high-risk procedure with a high perioperative mortality rate with possible recurrence. We aim to summarize our experience using a conservative approach with medical therapy. Methods We retrospectively reviewed records of patients who experienced pump thrombosis after LVAD implantation with HeartWare HVAD at our institution, from November 2010 to March 2016. Device thrombosis (DT) was divided into suspected (SDT) and confirmed (CDT). A conservative approach using thrombolysis and heparin was used in all patients. Results A total of 32 HeartWare HVAD pumps were implanted. Mean age was 59 ± 10 years and the mean time on mechanical support was 19.29 months (± 14.06). Pump thrombosis occurred in 7 patients (0.14 patients/year) after a mean time of 733 (231–1,606) days after LVAD implantation. Three out of 7 cases had t...

The patient initially started low-molecular-weight heparin therapy and then, after the onset of an ischemic stroke, switched to dabigatran etexilate (DE). The patient had progressive recovery of cardiac function for which the device was explanted. No thrombotic or bleeding events occurred during DE therapy.

Despite these advantages, LVADs are not free from risks. Among all adverse events (AE), pump thrombosis and bleeding, especially of the gastrointestinal (GI) tract, have been reported to occur with increasing frequency in some CF-LVADs. The INCOR LVAD system is a third-generation, continuous flow, axial pump with active magnetic levitation, avoiding the potential downsides of mechanical bearings. Methods The aim of this retrospective study was to review the Italian clinical experience with the INCOR LVAD and to determine the prevalence of GI bleeding and pump thrombosis. All patients implanted between January 2006 and May 2012 were considered eligible. Results The total population consisted of 42 patients. LVAD indication was BTT in 36 (86%) and DT in 6 (14%) patients; 31 patients (74%) were INTERMACS class 1 or 2. Mean support time was 52...

Acute fulminant myocarditis (AFM) may represent a life-threatening event, characterized by rapidly progressive cardiac compromise that ultimately leads to refractory cardiogenic shock or cardiac arrest. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides effective cardiocirculatory support in this circumstance, but few clinical series are available about early and long-term results. Data from a multicenter study group are reported which analyzed subjects affected by AFM and treated with VA-ECMO during a 5-year period. Method. From hospital databases, 57 patients with diagnoses of AFM treated with VA-ECMO in the past 5 years were found and analyzed. Mean age was 37.6 ± 11.8 years; 37 patients were women. At VA-ECMO implantation, cardiogenic shock was present in 38 patients, cardiac arrest in 12, and severe hemodynamic instability in 7. A peripheral approach was used with 47 patients, whereas 10 patients had a central implantation or other access. Results. Mean VA-ECMO support was 9.9 ± 19 days (range, 2 to 24 days). Cardiac recovery with ECMO weaning was achieved in 43 patients (75.5%), major complications were observed in 40 patients (70.1%), and survival to hospital discharge occurred in 41 patients (71.9%). After hospital discharge (median follow-up, 15 months) there were 2 late deaths. The 5-year actual survival was 65.2% ± 7.9%, with recurrent self-recovering myocarditis observed in 2 patients (at 6 and 12 months from the first AFM event), and 1 heart transplantation. Conclusions. Cardiopulmonary support with VA-ECMO provides an invaluable tool in the treatment of AFM, although major complications may characterize the hospital course. Long-term outcome appears favorable with rare episodes of recurrent myocarditis or cardiacrelated events.

We used a transeptal approach since 1975 at our Institution to obtain adequate exposure of mitral valve in 135 patients (48 males, 87 females, mean age 47.4 +/- 11.8, range 12-68). A mechanical valve (Bjork = 120; Sorin = 15) was implanted in mitral position. Associated procedures were performed in the 66% of the patients and most of them were tricuspid repair. About half of the patients were at the second or third cardiac operation after a previous closed heart mitral commissurotomy 15.15 +/- 5.6 years before. Exposure was excellent in the 95% of the cases. Hospital mortality was 12.6% and significantly major in patients at redo operation. Three patients with a concomitant aortic valve replacement required a definitive pace-marker implantation. A complete follow-up was possible in all patients who survived at operation. Actuarial survival rate at 10 years in 83% and at 20 years is 70%. Freedom from all event...

The use of left ventricular mechanical support devices has the potential to impart hemodynamic stability and to delay surgical treatment until such time as scar tissue forms around the defect, sufficient to hold a suture patch.From May 2004 through July 2007, 5 patients who were in cardiogenic shock as a consequence of acute posterior ventricular septal defect underwent early implantation of a transfemoral microaxial Impella® Recover® LP 5.0 Support System as mechanical support (bridge to surgery).The mean duration of support by the left ventricular assist device was 14.4 ± 6 days. No one died during assistance. The device reduced left-to-right shunting, systolic pulmonary artery pressure, central venous pressure, and pulmonary capillary wedge pressure. Liver, kidney, and lu...

Devicerelated infections remain the 'Achilles heel' of mechanical circulatory support and wound complications after VAD placement are a formidable challenge to surgeons. Up to 25% of deaths in VAD patients are due to systemic sepsis, which occurs in 11-26% of patients and bacteria that are common pathogens including Staphylococcus, Pseudomonas, Enterococcus, and Candida. Sepsis, infection of implanted pump components, and infections of percutaneous drivelines continue to limit survival. The Berlin Heart-EXCOR VAD is a para-corporeal pulsatile system that has been successful in patients with severe biventricular dysfunction. We report a case of a 35-year-old male suffering from a postischemic cardiomyopathy who received an EXCOR biventricular assist device as a bridge to transplant. During the assistance the patient developed concomitant methicillin-resistant Staphylococcus aureus infection of implanted pump components which was resistant to conventional therapy. The patient developed sepsis with splenic infarctions due to septic embolization which was successfully treated with a heart transplant. In some extreme cases of VAD infections, such as this, the only therapeutic option is transplantation or device replacement.
