The transaortic Morrow procedure is the current gold standard for hypertrophic obstructive cardiomyopathy (HOCM) patients who are resistant to maximum drug therapy. It is controversial whether concomitant mitral valve intervention is necessary. Only a few centers apply for concomitant anterior mitral leaflet extension with a bovine or autologous pericardial patch to further decrease systolic anterior motion. Our aim is to assess the primeval outcomes of thoracoscopic transmitral myectomy with anterior mitral leaflet extension (TTM-AMLE) in symptomatic HOCM patients.
Between April 2019 and November 2020, 18 consecutive HOCM patients who underwent TTM-AMLE were enrolled in this study. Preoperative, postoperative, and follow-up outcomes were compared and statistically analyzed.
The mean age was (50.17 ± 6.18) years and 10 (55.56%) were males. 18 (100%) patients had mitral regurgitation preoperatively, and they all successfully underwent TTM-AMLE with a median cardiopulmonary bypass and aortic cross-clamp tm/s, p < .001) and the degree of mitral regurgitation (6.99 ± 4.47 cm
vs. 2.22 ± 1.51 cm
, p = .001) were significantly decreased, with a significant reduction in the proportion of systolic anterior motion (94.44% vs. 16.67%, p < .001).
The TTM-AMLE is a safe and effective surgical approach for selected patients with HOCM. In our series, it provides excellent relief of left ventricular outflow tract obstruction, while significantly eliminating mitral regurgitation. The early outcomes of TTM-AMLE are satisfactory, but further studies and longer follow-ups are awaited.

Invasive hemodynamics may provide a more nuanced assessment of cardiac function and risk phenotyping in patients undergoing cardiac surgery. The systemic pulse pressure (SPP) to central venous pressure (CVP) ratio represents an integrated index of right and left ventricular function and thus may demonstrate an association with valvular heart surgery outcomes. Selleckchem 4-Aminobutyric This study hypothesized that a low SPP/CVP ratio would be associated with mortality in valvular surgery patients.
This retrospective cohort study examined adult valvular surgery patients with preoperative right heart catheterization from 2007 through 2016 at a single tertiary medical center (n = 215). Associations between the SPP/CVP ratio and mortality were investigated with univariate and multivariate analyses.
Among 215 patients (age 69.7 ± 12.4 years; 55.8% male), 61 died (28.4%) over a median follow-up of 5.9 years. A SPP/CVP ratio <7.6 was associated with increased mortality (relative risk 1.70, 95% confidence interval [CI] 1.08-2.67, p = .019) and increased length of stay (11.56 ± 13.73 days vs. 7.93 ± 4.92 days, p = .016). It remained an independent predictor of mortality (adjusted odds ratio 3.99, 95% CI 1.47-11.45, p = .008) after adjusting for CVP, mean pulmonary artery pressure, aortic stenosis, tricuspid regurgitation, smoking status, diabetes mellitus, dialysis, and cross-clamp time.
A low SPP/CVP ratio was associated with worse outcomes in patients undergoing valvular heart surgery. This metric has potential utility in preoperative risk stratification to guide patient selection, prognosis, and surgical outcomes.

Late surgical start times have been associated with a multitude of adverse consequences such as increased cost, delay in treatment, increase in medical errors, and patient complications. From October 1, 2018 to September 30, 2019, 47% (67/144) of non-emergent cardiac cases in our institution had a late start by our institutional standard. Our objective was to decrease the percentage of late start non-emergent cardiac cases from 47% to 37% by October 2020.
All non-emergent cardiac surgical procedures as first start cases in a single institution were included in our study. Preintervention cardiac surgical cases were reviewed from October 1, 2018 to February 28, 2020 to determine key drivers contributing to late start times. A multidisciplinary team was formed and utilized A3 process and problem-solving strategies to address our objective. A multipronged intervention approach was used to address key drivers contributing to late start times.
All interventions were implemented in March 2020. Postintervention data was collected from March 1, 2020 to February 28, 2021, on all non-emergent cardiac surgical procedures. The percentage of non-emergent cardiac cases starting after 800 a.m. decreased to 27% (17/62). The decrease in late start cases translated into saving an average of 45min of operating room (OR) time (average cost savings of ~$5,000/case). Additionally, staff reported improved job satisfaction.
Delayed surgical case start times can have negative effects on patients, employees, and lead to increase costs of medical care. Our research has shown adherence to on-time surgical start can improve OR efficiency, decrease cost, and improve employee satisfaction.

Hemostatic disturbances with coronavirus disease 2019 (COVID-19) can predispose to tricuspid and right heart thrombi in very rare instances.
We describe a 29-year-old female patient without a previous cause of thrombosis who developed large tricuspid valve thrombus (TVT) and moderate-to-severe tricuspid regurgitation (TR) during the course of COVID-19 infection.
Persistant fever and tachycardia with thrombocytopenia and high d-dimer increased the index of suspicion. The diagnosis was made by bedside transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR). Surgery was performed for thrombectomy and tricuspid valve replacement with a tissue valve.
Detection of TVT in COVID-19 patients on the basis of high index of suspicion, bedside TTE and noninvasive CMR helps early surgical treatment and subsequent reduction of mortality and hospital stay.
Detection of TVT in COVID-19 patients on the basis of high index of suspicion, bedside TTE and noninvasive CMR helps early surgical treatment and subsequent reduction of mortality and hospital stay.A 12-year-old male child with atypical chest pain and fatigue since past 3 months underwent cardiac magnetic resonance (CMR) imaging for suspicious globular mobile mass detected in the left ventricle on a transthoracic echocardiography. CMR revealed peripheral vascular blush on the first pass perfusion images with centripetal progressive intensely bright enhancement on late gadolinium-enhanced images. Further confirmation and histological diagnosis of the tumor was made through transaortic aortic resection of the mass.
Routine use of central venous access is needed in children undergoing open heart surgery for pressure monitoring and inotrope infusion. We sought to evaluate the efficiency and safety of routine use of transthoracic intracardiac lines (ICLs) in patients undergoing cardiac surgery and to compare them to patients who have been previously treated with traditional central venous lines (non-ICLs).
Retrospective review of charts of all patients who underwent cardiac surgery and had an ICL inserted in the operating room. Case control matching was done with similar patient in which ICL was not inserted. Patients characteristics, diagnosis, operative, and intensive care datawere collected for each patient and analyzed.
A total number of 376 patient records were reviewed (198 ICL patientsand 178 non-ICL patients). Umbilical line and non-ICL durations were longer in the non-ICL group. ICL duration was the longest of all lines, averaging 12.87 ± 10.82 days. The necessity for multiple line insertions (˃2 insertions) was significantly higher in the non-ICL group, with a relative risk ratio of 3.24 (95% confidence interval 1.617-6.428). There was no statistical difference of infections rate and line complications between the two groups.
ICLs are safe in infants undergoing cardiac surgery and can be kept in place for a long period of time with a low rate of line complications and infection. Routine use of ICLs reduces the number of central venous catheter placement in this complex patient population.

The prevalence and impact of pulmonary embolism (PE) in patients with lead-related infective endocarditis undergoing transvenous lead extraction (TLE) are unknown.
Twenty-five consecutive patients with vegetations ≥10 mm at transoesophageal echocardiography were prospectively studied. Contrast-enhanced chest computed tomography (CT) was performed before (pre-TLE) and after (post-TLE) the lead extraction procedure.
Pre-TLE CT identified 18 patients (72%) with subclinical PE. The size of vegetations in patients with PE did not differ significantly from those without (median 20.0 mm [interquartile range 13.0-30.0] vs. 14.0 mm [6.0-18.0], p = 0.116). Complete TLE success was achieved in all patients with 3 (2-3) leads extracted per procedure. There were no postprocedure complications related to the presence of PE and no differences in terms of fluoroscopy time and need for advanced tools.In the group of positive pre-TLE CT, post-TLE scan confirmed the presence of silent PE in 14 patients (78%). There were no patients with new PE formation. Large vegetations (≥20 mm) tended to increase the risk of post-TLE subclinical PE (odds ratio 5.99 [95% confidence interval (CI) 0.93-38.6], p = 0.059).During a median 19.4 months follow-up, no re-infection of the implanted system was reported. Survival rates in patients with and without post-TLE PE were similar (hazard ratio 1.11 [95% CI 0.18-6.67], p = 0.909).
Subclinical PE detected by CT was common in patients undergoing TLE with lead-related infective endocarditis and vegetations but was not associated with the complexity of the procedure or adverse outcomes. TLE procedure seems safe and feasible even in patients with large vegetations.

Increasing evidence has suggested improved outcomes in atrial fibrillation (AF) patients with heart failure (HF) undergoing catheter ablation (CA) as compared to medical therapy. We sought to investigate the benefit of CA on outcomes of patients with AF and HF as compared to medical therapy.
A systematic review of PubMed, Embase, and Cochrane Central Register of Clinical Trials was performed for clinical studies evaluating the benefit of CA for patients with AF and HF. Primary endpoint was all-cause mortality. Secondary endpoints included atrial-arrhythmia recurrence and improvement in left ventricular ejection fraction (LVEF). Eight randomized controlled trials were included with a total of 2121 patients (mean age 65 ± 5 years; 72% male). Mean follow-up duration was 32.9 ± 14.5 months. All-cause mortality in patients who underwent CA was significantly lower than in the medical treatment group (8.8% vs. 13.5%, RR 0.65, 95%confidence interval [CI] 0.51-0.83, p = .0005).
