In this case we briefly describe the case of an old woman presenting with acute exertional dyspnea due to hyperacute Sapien Valve thrombosis.

Transcatheter aortic valve implantation in patients with age ≤70 years: experience from two leading structural heart disease centers.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is emerging as an appealing management strategy for patients with severe aortic stenosis at intermediate, high or exceedingly high risk, but its risk-benefit profile in younger patients is less certain. We aimed to explore the outlook of patients aged 70 years or less and undergoing TAVI at 2 high-volume Italian institutions. METHODS: We retrospectively collected baseline, imaging, procedural and outcome features of patients with age ≤70 years in whom TAVI was attempted at participating centers between 2012 and 2021. Non-parametric tests and bootstrap resampling were used for inferential purposes. RESULTS: A total of 39 patients were included, out of >3000 screened with heart team involvement and >1500 receiving TAVI. Most common or relevant indications for TAVI reduced life expectancy (e.g. cardiogenic shock or severe left ventricular systolic dysfunction), chronic obstructive pulmonary disease, morbid obesity, active or recent extra-cardiac cancer, porcelain aorta, neurologic disability, cirrhosis, or prior surgical aortic valve replacement, as well as extreme cachexia, and Hutchinson-Gilford progeria. At least two contemporary high-risk features were present in most cases. Transapical access was used in 5 (12.8%) cases, and a sheathless approach in 15 (38.5%). A variety of devices were used, including both balloon- and self-expandable devices. Clinical outcomes were satisfactory, despite the high-risk profile, at both short- and mid-term, with no in-hospital death, and 5.1% (95% confidence interval 0-12.8%) mortality at a median follow-up of 15 months (minimum 1; maximum 85). Notably, no case of significant valve deterioration requiring reintervention occurred. CONCLUSIONS: In carefully selected patients with 70 years or less of age and prohibitive risk for surgery or reduced life expectancy, TAVI represents a safe option with a favorable mid-term survival and low rate of adverse events.

3D mitral annulus echocardiography assessment in patients affected by degenerative mitral regurgitation who underwent mitral valve repair with flexible band.

BACKGROUND: Degenerative mitral valve (MV) regurgitation (DMR) shows significative mitral annulus (MA) alterations; mitral valve repair (MVR) seeks to restore annular geometry and function, and the current use of flexible band seams to respect most annular mobility reducing parietal stress. Parameters of MV geometry obtained by 3D transesophageal echocardiography (3D-TTE) analysis are crucial for surgical planning and postoperative success. The aim of this study was to assess, by means of a dedicated software, the variations of MA geometry and function in patients affected by DMR compared to controls and after MVR with flexible band. METHODS: We enrolled 32 patients (cases) with severe DMR who underwent MVR using flexible band; we compare this group with 20 controls. The TEE with 3D MV images acquisition was performed in both groups and then analyzed in postprocessing by using a dedicated software. RESULTS: There were no anthropometrics differences between cases and controls, both presented normal left ventricular ejection fraction. DMR group showed a significant increase of annulus dimensional parameters (p = .001) and alteration of nonplanarity comparing to controls (p < .05). The annuloplasty with flexible band induces a considerable reduction of MV dimensions comparing to preoperative data and restores physiological mobility and nonplanarity. There were no statistical differences between postoperative DMR and controls data, except for nonplanarity parameters (p ~.05), maybe influenced by hemodynamic settings. CONCLUSIONS: MVR with annuloplasty using flexible band appears able to reinstate a more physiological anatomic conformation of the MA, without compromising its dynamic properties.

Prediction of right ventricular failure after left ventricular assist device implantation: role of vasodilator challenge.

AIMS: Pulmonary artery pulsatility index (PAPi) is an indicator of right ventricular (RV) function and an independent predictor of right ventricular failure (RVF) following left ventricular assist device (LVAD) implantation. Administration of vasodilator challenge during right heart catheterization (RHC) could reduce RV workload allowing a better assessment of its functional reserve. METHODS AND RESULTS: Patients undergoing LVAD implantation at our Institution between May 2013 and August 2021 were enrolled. Only patients who had undergone RHC and vasodilator challenge with sodium nitroprusside were analyzed. We collected all available clinical, instrumental, and haemodynamic parameters, at baseline and after nitroprusside infusion and evaluated potential associations with post-LVAD RVF. Of the 54 patients analyzed, 19 (35%) developed RVF after LVAD implantation. Fractional area change (FAC) (OR: 0.647, CI: 0.481-0.871; P = 0.004), pulmonary artery systolic pressure (PASP) (OR: 0.856, CI: 0.761-0.964; P = 0.010), and post-sodium nitroprusside (NTP) PAPi (OR: 0.218, CI: 0.073-0.653; P = 0.006) were independent predictors of post-LVAD RVF. The model combining FAC, PASP, and post-NTP PAPi demonstrated a predictive accuracy of 90.7%. Addition of post-NTP PAPi significantly increased the predictive accuracy of the European Registry for Patients with Mechanical Circulatory Support right-sided heart failure risk score [79.4 vs. 70.4%; area under the curve (AUC): 0.841 vs. 0.724, P = 0.022] and the CRITT score (79.6% vs. 74%; AUC: 0.861 vs. 0.767 P = 0.033). CONCLUSION: Post-NTP PAPi has observed to be an independent predictor of RVF following LVAD implantation. Dynamic assessment of PAPi using a vasodilator challenge may represent a method of testing RV functional reserve in candidates for LVAD implantation. Larger and prospective studies are needed to confirm this hypothesis.

A tricky electrocardiogram: cocaine induced Brugada type 2 phenocopy.

BACKGROUND: The pharmacological effects of cocaine have been associated with different types of cardiac dysrhythmias and with Brugada pattern on the ECG, but currently only type 1 pattern has been described. We report a case of a transient Brugada type 2 pattern in a young cocaine abuser. METHOD: We report the clinical presentation of a 32-year-old male with a history of cocaine abuse. RESULT: The treatment and the resolution of the acute phase have been described; moreover we discuss the pathophysiology of the Brugada phenocopy in this specificclinical setting. CONCLUSION: The clinical impact of our case report underscores the necessity of prompt physician awareness of any ECG abnormality besides myocardial infarction in patients with cocaine abuse, such as any Brugada pattern, which could lead to ominous ventricular arrhythmias.

Critical subaortic stenosis due to fibromuscular ridge in a 66-year-old woman: 2D-3D echocardiography findings.

Subvalvular aortic stenosis (SAS) can be either a fixed stenosis resulting from subaortic anatomical obstacle or a dynamic stenosis because of hypertrophic cardiomyopathy. Here, we report a patient with a rare subaortic circumferential fibromuscular tunnel who became unusually symptomatic in her sixth decade of life. Transthoracic and mostly transesophageal echocardiography with 3D application is the preferred diagnostic modality. Indications for surgery include symptoms and LVOT gradient of 50 mm Hg. Our purpose is an image focus on this infrequent case.

Asymptomatic Cardiac Metastases From Esophageal Cancer: A Case Report Of Ante-mortem Detection And Literature Review.

Metastatic spread to the heart from neoplasms is very rare, often silent and rarely gains clinical attention. Usually, it correlates with widespread metastatic disease and is suggestive of a poor prognosis. Most cardiac metastases (CM) are detected following post-mortem studies with only a handful reported antemortemly. Here, we report a case of an asymptomatic cardiac metastasis from esophageal carcinoma and a review of the literature. In late July 2014, a 73-year-old woman diagnosed with locally advanced esophageal squamous cell carcinoma was admitted to our institution. Cardiothoracic metastases were not detected at basal computed tomography (CT) scan. The patient was submitted to concurrent cisplatin and radiotherapy. Just before surgery, a CT scan revealed two metastases in the right ventricle and in the interventricular septum. Transthoracic echocardiography and an endomyocardial biopsy confirmed the diagnosis of squamous cell carcinoma from the esophageal origin. In February 2015, chemotherapy was started, but after two courses of gemcitabine, a pulmonary embolism and then a congestive heart failure caused death of the patient on April 2015. Reviewing the literature, 14 cases with an antemortem diagnosis of CM from esophageal cancer were reported. Our patient should be the fifteenth case with an uncommon presentation without symptoms or signs in the diagnosis. Our case highlights that patients should be evaluated using echocardiography for CM, even if asymptomatic.

The Role of Heart Team Approach in Penetrating Cardiac Trauma: Case Report and Review of the Literature.

Penetrating cardiac trauma has been increasing in clinical experience and is joined to important morbidity and mortality. A case of a 38-year-old female with history of postpartum depression was reported, admitted to our department for cardiac tamponade due to penetrating self-inflicted multiple stab wound of the chest complicated by rupture of anterior left ventricular wall and traumatic ventricular septal defect. Following the unstable hemodynamic instability, a combined therapeutic strategy was chosen: surgery and transcatheter implantation to correct free wall ventricle damage and traumatic ventricular septal defect, respectively.
