Abnormal mitral valve apparatus in a case of hypertrophic obstructive cardiomyopathy: Intraoperative transesophageal echocardiography.

We present a case where intraoperative transesophageal echocardiography played a crucial role in defining the etiology of LVOT obstruction that subsequently helped in deciding the surgical plan. PMID: 30052226 [PubMed - in process]

ConclusionsPatients with aortic stenosis most often develop symmetric hypertrophy; however, a small subset has asymmetric septal hypertrophy leading to left ventricular outflow tract obstruction. In cases of severe aortic stenosis, however, evidence of left ventricular outflow tract obstruction via both symptoms and echocardiographic findings may be minimized due to extremely high afterload on the left ventricle. Diagnosing a left ventricular outflow tract obstruction as the cause of hemodynamic instability during transcatheter aortic valve replacement, in the absence of abnormal findings on echocardiogram preoperatively, ...

HYPERTROPHIC CARDIOMYOPATHY (HCM) is a complex disease with highly variable phenotypes. The obstructive variant (hypertrophic obstructive cardiomyopathy [HOCM]) is characterized by impedance to systolic flow across the left ventricle outflow tract (LVOT).1,2 Although much emphasis is placed appropriately on LVOT gradients as a measure of the degree of obstruction, this clinical focus may miss deeper hydraulic complexity. The flow through the left ventricular cavity in HOCM often is distorted and multiple anatomical anomalies can coexist resulting in multiple gradients independent of the classic “dagger shaped” ...

This study’s purpose was to review non-cardiac surgery (NCS) in patients with hypertrophic obstructive cardiomyopathy (HOCM) to examine perioperative management and quantify postoperative mortality and worsening heart failure.

We report successful anesthetic management in a case of living donor liver transplantation with hypertrophic obstructive cardiomyopathy using ketamine, propofol, and fentanyl to avoid vasodilation by anesthetic agents. In addition, landiolol, phenylephrine, and low-dose dopamine were administered to prevent left ventricular outflow tract obstruction, and were found to be effective for improving acute hemodynamic changes during surgery. In the case of this patient, the combination of transesophageal echocardiography and a pulmonary artery catheter was beneficial for intraoperative hemodynamic monitoring. PMID: 24597212 ...

OBJECTIVES The purpose of this retrospective study was to analyse the pathogenesis and the treatment strategies of hypertrophic obstructive cardiomyopathy (HOCM) with the concomitant mitral valve abnormalities. METHODS Between October 1996 and December 2009, 76 patients with the HOCM underwent the ventricular septal myotomy–myectomy in Fuwai hospital. There were 51 males and 25 females aged between 6 and 68 years (mean: 37.18 ± 15.85 years) old. All the patients had left ventricular outflow tract (LVOT) obstruction with a resting or physically provoked gradient of ≥50 mmHg and the systolic anterior movemen...

Conclusions: Careful bedside examination with transthoracic echocardiography was useful in making diagnosis and in guiding appropriate therapy for this patient. Clinicians should be aware that systolic anterior motion of the mitral valve may present as unexplained sudden hypoxemia in the perioperative setting.
