However, severe cases may progress to cardiogenic shock (CS), requiring mechanical circulatory support (MCS). High-profile transvalvular pumps (HPTP), a form of percutaneous ventricular assist device, offer promising hemodynamic support in acute heart failure. This report explores HPTP use in SI-CM-related CS through two complex clinical cases. Case Summary: Two elderly female patients presented with severe CS secondary to apical-variant SI-CM. Case 1 involved a 67-year-old woman with sepsis, colonic perforation, and recurrent SI-CM, leading to profound low-output shock despite multiple vasopressors and inotropes. HPTP was implanted via the axillary artery, allowing for surgical management of intra-abdominal pathology and eventual cardiac recovery. Case 2 featured a 77-year-old woman with multifocal pneumonia, severe mitral regurgitation, and complete heart block. HPTP implantation stabilized her hemodynamics, facilitated extubation, and led to full recovery of ventricular function. Results: Both patients showed marked improvement in cardiac output and systemic perfusion following HPTP insertion. Echocardiograms post-device removal revealed normalization of left ventricular ejection fraction (55\u201364%). Hemodynamic data confirmed reduced pulmonary capillary wedge pressure and systemic vascular resistance. Conclusion: These cases highlight the potential of HPTP in managing SI-CM-related CS, especially when traditional therapies are inadequate or contraindicated. HPTP can rapidly restore hemodynamic stability and support myocardial recovery. While current data are limited, these observations underscore the need for broader investigation into the role of HPTP in this setting.<\/jats:p>","DOI":"10.3390\/jcm14093225","type":"journal-article","created":{"date-parts":[[2025,5,6]],"date-time":"2025-05-06T09:08:56Z","timestamp":1746522536000},"page":"3225","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High Profile Transvalvular Pump Assisted Recovery for Takotsubo Cardiomyopathy: A Case Series"],"prefix":"10.3390","volume":"14","author":[{"given":"Jordan","family":"Young","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Baylor Scott and White Health\u2014Temple, Temple, TX 76508, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"McGrade","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Baylor Scott and White Health\u2014Temple, Temple, TX 76508, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaime","family":"Hernandez-Montfort","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Baylor Scott and White Health\u2014Temple, Temple, TX 76508, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5841-9491","authenticated-orcid":false,"given":"Jerry","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Baylor Scott and White Health\u2014Temple, Temple, TX 76508, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e7","DOI":"10.1016\/j.jacc.2015.03.036","article-title":"2015 scai\/acc\/hfsa\/sts clinical expert consensus statement on the use of percutaneous mechanical circulatory support devices in cardiovascular care: Endorsed by the american heart assocation, the cardiological society of india, and sociedad latino americana de cardiologia intervencion; affirmation of value by the canadian association of interventional cardiology-association canadienne de cardiologie d\u2019intervention","volume":"65","author":"Rihal","year":"2015","journal-title":"J.
